     BACKGROUND OF INVENTION 
     Field of Invention 
     The present invention is directed toward improvements in mass timber building construction, and more particularly, the procurement, prefabrication and construction of multi-story mass timber buildings made from fire-protected laminated timber products, offering improved defense against the ravaging and destructive forces of fire. 
     Brief Description of the State of Knowledge in the Art 
     Over the past few decades, there has been a movement towards using engineering wood products (EWPs) based on young immature timber growth, for reasons of sustainability, and the fact that old mature timber is either not available or too expensive to meet current market demands in the wood-framed building industry. When using engineered wood products EWPs, it is possible to fabricate wood beams, panels and assemblies that can span great lengths and support great loads, while being manufactured from small, young and immature trees, such as Fir, Spruce and Pine. 
     Among the many different kinds of EWP innovations developed over the years, mass timber products have been receiving growing interest. This interest is due primarily on the capacity of certain mass timber products (e.g. cross-laminated timber or CLT) to replace structural steel and concrete in many applications, and allow architects to design and construct high-rise and multi-story buildings  1  from mass timber CLT, as illustrated in  FIG. 1A . 
     As shown in  FIG. 1B , conventional mass timber building products can be organized into two product categories comprising: (i) glued products, including glue laminated timber (GLT)  2 , structural composite lumber (SCL)  3 , and cross-laminated timber (CLT)  4 ; and (ii) non-glued products, including dowel laminated timber (DLT)  5 , nail laminated timber (NLT)  6 , cross nail laminated timber (CNLT)  7 , and interlocking cross laminated timber (ICLT)  8 . 
     For over 20 years, conventional CLT products have been widely used in Europe, and in recent years, CLT products have been gaining ground in North America. The reasons for this growing interest is that CLT technology enables architects to design and construct buildings having great height and the capacity to sustain great loads presented during Earthquakes and other natural disasters. The environmental and construction benefits of CLT make it a growth industry, with more manufacturing plants opening each year. 
     Cross-laminated timber (CLT) is a promising wood-based structural component and has potential to provide cost-effective building solutions for residential, commercial and institutional buildings as well as large industrial facilities. Market acceptance of CLT requires that it meet the applicable building code requirements. CLT elements are used in building systems in a similar manner to concrete slabs and solid wall elements, as well as those from heavy timber construction, by avoiding concealed spaces due to the use of massive timber elements, thus reducing the risk of fire spread beyond its point of origin. Moreover, CLT construction typically uses CLT panels for floor and load-bearing walls, which allow fire-rated compartmentalization, thus again reducing the risk of fire spread beyond its point of origin. 
     In general, each CLT panel is custom built to the designer&#39;s specification. CLT panel size is governed by the press which typically measures 15 m×3.5 m. Panel thickness depends on the intended load and span. The most CLT panels have common configurations of 3, 5 or 7 layers, with cumulative panel thicknesses between 60 mm and 250 mm. The cross lamination feature of CLT panels provides dimensional stability, strength and rigidity. This makes CLT a viable alternative to conventional wood-framing, concrete, masonry and steel in many applications. CLT panels can be used to construct an entire mass timber building, as both the lateral and vertical load resisting system, or for select elements such as the roof, floors or walls. The CLT panel as a structural panel element is also used as a superior industrial matting, bridging and retaining wall product that replaces heavy timbers, steel, and concrete. 
     Below are some reasons why CLT has the potential to redefine construction around the world:
         CLT panels can be produced in large size (up to 15 m×3.5 m and beyond), and fit together quickly on site making building construction much faster and easier.   For both large and small buildings, CLT panels connect together as a complete engineered wood building solution.   Each CLT panel is custom-made to suit the structural needs of the project and required appearance.   CLT panels are manufactured using the latest CNC machining technology to ensure high precision and eliminate site waste.   CLT panels are safe to erect, weighing only 20% as much as concrete.   CLT panels are safe to inhabit, being strong and flexible under load.   CLT is sustainable, as wood stores carbon to help our planet environmentally.   CLT panel construction out-performs conventional wood-framed construction in air-tightness, thermal insulation, internal moisture management, acoustic insulation and fire resistance.   For many building types, CLT construction systems out-perform steel and concrete on a basis of cost.   Also, CLT can be manufactured to customized dimensions and in varying panel sizes, while panel length is typically limited by transportation restrictions.

       FIG. 3  shows the various stages of processing supported within a conventional factory for producing cross-laminated timber (CLT) construction components. In general, a conventional CLT panel factory  12  comprises many stages including: a controlled drying stage  12 A for drying structural timber  12 B to a humidity of 12%+ or −2% or less and then visual or machine strength grading of boards; a finger jointing stage  12 C for producing finger-jointed laminations from graded boards or board sections; a lamination planing stage  12 D for planing and dimensioning finger-jointed laminations; a stacking and adhesive stage  12 E for applying adhesive to the planed laminations; a stacking, pressing and curing stage  12 F for pressing and curing the finger-jointed laminations with adhesive into a cross-laminated timber (CLT) piece using a hydraulic or vacuum process; a CNC fabrication stage  12 G for trimming the dimensions of the CLT element, including cutting widows, doorways and other apertures required by the design; and a packaging stage  12 H for packaging the CLT elements  121  for shipping to a building destination.

FIG. 5C  shows the conventional CLT panel  21  being lowered into position on a mass timber building being constructed, using the crane  20  shown in  FIG. 5A . 
     Conventional CLT Panel Technology Falls Significantly Short on Providing Fire Protection 
     Despite performing well in standard ASTM E119 structural fire performance tests, and offering great promise as a cost-effective building solution for residential, commercial and institutional buildings as well as large industrial facilities, conventional CLT panels and assemblies generally fall short on fire protection and safety and can only offer a Class-B fire-protection rating based on ASTM E84 test standards. Such low fire-protection ratings are because conventional raw CLT has high flame spread rate (FSR) and high smoke development (SD) characteristics when a CLT panel burns in the presence of fire, ultimately producing a thick layer of char  23 A from pyrolysis, as illustrated in the massive solid-wood CLT panel sample  23  shown in  FIG. 6A . This charring of a CLT panel  23  can slow down the fire and protect the inner core from heating, while keeping CLT panels structurally sound, so that CLT panels, having more layers of wood, will last longer in a fire. However, as all CLT buildings rely on its Class B char value, architects are forced to specify that every CLT column and CLT panel is made thick and wide enough in size, from built up layers of laminated timber, so that the CLT panels will support fire longer than steel beams and columns, much like a tree in a forest fire. This overdesign requirement with conventional CLT panels increases the cost of CLT construction. 
     Moreover, conventional raw CLT does not offer any defense against “flashover” during a building fire. A flashover is the near-simultaneous ignition of most of the directly exposed combustible material in an enclosed area. When certain organic materials are heated, they undergo thermal decomposition and release flammable gases. Flashover occurs when the majority of the exposed surfaces in a space are heated to their auto-ignition temperature and emit flammable gases. Flashover normally occurs at 500° C. (932° F.) or 590° C. (1,100° F.) for ordinary combustibles, and an incident heat flux at floor level of 20 kilowatts per square meter (2.5 hp/sq ft). Firemen know this fact about raw conventional CLT building materials, and therefore will not defend a burning mass timber CLC building unless they are attempting to save human lives because of the dangerous condition raw CLT building material presents. 
     Therefore, there is a great need in the art to raise the bar on the limited fire-protection that Class-B charring offers to CLT building materials, and provide true Class-A fire-protection for tenants, fireman, police, first responders, building owners and visitors, and raise the standards of safety for humans who live and work in affordable buildings constructed using sustainable renewable resources, such as cross-laminated timber (CLT), and other engineered timber products. 
     In effort to prevent fire destruction of mass timber buildings, it is essential to understand the nature of the fire cycle before understanding how flame retardants, inhibitors and extinguishers work to suppress and extinguish building fires. 
     In  FIG. 6B , the fire cycle  24  is graphically illustrated as having four essential components: (i) an ignition source (e.g., heat, incandescent material, a small flame); (ii) fuel material (e.g., wood, wax, fuel, etc.); (iii) oxygen; and (iv) free radicals (H+, OH−, O−)  25  associated with the combustion process. 
     In general, the ignition source can be any energy source (e.g. heat, incandescent material, a small flame, a spark, etc.). The function of the ignition source is to start the material to burn and decompose (pyrolysis), releasing flammable gases. If solid materials in the ignition source do not break down into gases, they remain in a condensed phase. During this condensed phase, the material will slowly smolder and, often, self-extinguish, especially if the material beings to “char,” meaning that the material creates a carbonated barrier between the flame and the underlying material. 
     In the gas phase, flammable gases released from the burning and decomposing material are mixed with oxygen, which is supplied from the ambient air. In the combustion zone, or the burning phase, fuel, oxygen and free radicals (i.e. H+, OH−, O−) combine to create chemical reactions  25  that produce visible flames to appear. The fire then becomes self-sustaining because, as it continues to burn the material, more flammable gases are released, feeding the combustion process. 
     In general, flame retardants, or fire inhabitants, act in three ways to stop the burning process, and consequently, can be classified by how these agents work to stop a burning flame. These three methods of flame retardation/inhibition/extinguishing are described below: 
     (i) Disrupting the combustion stage of a fire cycle, including avoiding or delaying “flashover,” or the burst of flames that engulfs a room and makes it much more difficult to escape; 
     (ii) Limiting the process of decomposition by physically insulating the available fuel sources from the material source with a fire-resisting “char” layer; and 
     (iii) Diluting the flammable gases and oxygen concentrations in the flame formation zone by emitting water, nitrogen or other inert gases. 
     One effective family of prior art clean fire inhibiting chemical (CFIC) liquid has been supplied by PT. Hartindo Chemicatamata Industri of Jakarta, Indonesia (a/k/a Hartindo Anti Fire Chemicals) for many years now, and used by many around the world in diverse anti-fire applications. Current chemical formulations marketed by Hartindo under AF11, AF21 and AF31 product designations, disrupt the combustion stage of the fire cycle by combining with the free radicals (H+, OH−, O−) that are produced during combustion. 
     Most prior art intumescent coatings, whether applied as paint or coatings on engineered wood products (EWPs), work differently from Hartindo&#39;s fire-inhibiting (anti-fire) chemicals, in that prior art intumescent coatings form a char layer when heated, acting as an insulating layer to the substrate of fuel source, to prevent the fuel source from burning. Prior art Pyrotite® magnesium-based cementitious coatings, as used in LP&#39;s FlameBlock® fire-rated OSB sheathing (i.e. sheeting), FlameBlock® I-Joists, and other FlameBlock® EWPs, release water when exposed to the heat of a fire, and thereby dilute the flammable gases and oxygen concentrations in the flame formation zone. 
     Another problem plaguing the mass timber market is that mass timber buildings are also vulnerable to mold and insects such as termites. 
     While various prior art methods have been proposed for providing fire-protection to engineered wood products (EWPs), such proposals have been generally inadequate, and there still exists a great need in the art for new and improved ways of providing EWPs with higher levels of fire protection, in the health and safety interests of building tenants and fireman. 
     Further, there is a growing demand for higher performance, fire-rated CLT building products for use in mass timber buildings in the single-family, multi-family and light commercial construction markets. 
     Also, there is a great need for better ways of designing and constructing high-rise and multi-story mass timber buildings that demonstrate improved defense against fire destruction, while overcoming the shortcomings and drawbacks of prior art methods and apparatus.

     DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS OF THE PRESENT INVENTION 
     Referring to the accompanying Drawings, like structures and elements shown throughout the figures thereof shall be indicated with like reference numerals. 
     Specification of Method of Designing and Constructing Multi-Story Mass Timber Buildings in Accordance with the Principles of the Present Invention so that Such Mass Timber Buildings Demonstrate Class-A Fire-Protection and Improved Resistance Against Fire Destruction 
       FIG. 7  describes the primary steps involved in the method of designing and constructing multi-story mass timber buildings in accordance with the principles of the present invention so that such mass timber building demonstrate Class-A fire-protection and resistance against fire destruction. As shown, the method comprises the two phases: an architectural design phase; and a building construction phase. 
     During the architectural design phase of a new multi-story mass timber building, the architect specifies the use of (i) Class-A fire-protected CLT building components, and (i) on-job-site Class-A fire-protected spray coating treatment of all raw/untreated and treated lumber using CFIC liquid after each completed section of the mass timber building, so as to ensure that a Class-A fire-protection coating is deposited or otherwise formed on the interior surface of all exposed wood surfaces within the mass timber building under construction. 
     As shown in  FIG. 7 , during the design phase, the building architect specifies the use of the on-job-site spray method and system of the present invention so that all (100%) of new construction lumber used on the building is Class-A fire-protected with a CFIC coating or film, to prevent fire ignition and flame spread in the building, during the construction phase, as well as after construction of the building is completed. According to the present invention, the building architect also specifies that factory-applied Class-A fire-protective CLT building components be used on exterior walls, exterior face of the roof, walls and floor sheathing, as it offers extra UV and moisture protection, against the natural elements. 
     During the prefabrication/production phase shown in  FIG. 7 , in a prefabricated mass timber building factory system supporting multiple production lines, as illustrated in  FIGS. 39A and 39B , prefabricated Class-A fire-protected mass timber building components are produced for use in constructing a pre-specified Class-A fire-protected mass timber building, managed and tracked using the system network  135  illustrated in  FIG. 41 . 
     During the construction phase shown in  FIG. 7 , the builder constructs the building in accordance with the architect&#39;s design specifications so as to provide a single-story or multi-story mass timber building having Class-A fire-protection and improved resistance against fire destruction. 
     In order to carry out the method described above, it will be helpful to describe several new and improved methods of producing Class-A fire-protected CLT and/or NLT building products in accordance with the principles of the present invention. Each of these improved Class-A fire-protected CLT/NLT building products can be used in the practice of the method described in  FIG. 7 , in combination with the practice of the method of spray-treating lumber and sheathing inside a prefabricated mass timber building under construction, as described in  FIGS. 39A through 45J , so as to construct and provide a prefabricated mass timber building with “double” Class-A fire-protection, having received in-factory and on-site Class-A fire-protection. 
     Specification of the Method of and Apparatus for Producing Class-A Fire-Protected Mass Timber Building Components in Accordance with the Principles of the Present Invention 
     While most fires start small, they often spread rapidly onto surrounding flammable surfaces. Before long, the phenomenon of flash over occurs, where superheated gases cause a whole room to erupt into flame within minutes. To prevent this dangerous event from occurring in a mass timber building, the present invention provides Class-A fire-protected mass timber building components, as shown in  FIGS. 8 through 19C , which bear multiple clear (i.e. transparent) surface coatings formed or other deposited by a number of processes including: 
     (i) dip-coating kiln dried timber pieces (i.e. timber laminations) in a clean fire inhibiting chemical (CFIC) liquid, preferably Hartindo AF21 Total Fire Inhibitor, developed by Hartindo Chemicatama Industri of Jakarta, Indonesia (commercially-available from Newstar Chemicals (M) SDN. BHD of Selangor Darul Ehsan, Malaysia http://newstarchemicals.com/products.html), then laminating these Class-A fire-protected timber laminations together (in different ways) to form mass timber building components in a particular configuration; and/or 
     (ii) spray coating a CFIC liquid (preferably Hartindo AF21 or AF31 Total Fire Inhibitor, and optionally containing a polymer, and anti-mold and anti-termite agents) over the exterior surfaces of the Class-A fire-protective mass timber building components; and optionally, 
     (iii) on-site spraying of the exterior wood surfaces of mass timber building components, with a CFIC liquid (e.g. preferably Hartindo AF31 Total Fire Inhibitor) after the (Class-A fire-protected) mass timber building components have been installed in a mass timber building architecture. 
     When so treated as taught and disclosed herein, these Class-A fire-protected mass timber building products will (i) prevent flames from spreading and flash over from occurring within a mass timber building, and (ii) confine a fire outbreak to the ignition source so that it can be readily extinguished, or allowed to go out by itself. 
     The preferred CFIC liquid for use in practicing the present invention is Hartindo AF21 Total Fire Inhibitor. The primary chemical constituents of Hartindo AF21 Total Fire Inhibitor include: monoammonium phosphate (MAP) (NH 4 H 2 PO 4 ); diammonium phosphate (DAP) (NH 4 ) 2 HPO 4 ; ammonium sulphate (NH 4 ) 2 SO 4 ; urea (CH 4 N 2 O); ammonium bromide (NH 4 Br); and tripotassium citrate C 6 H 5 K 3 O 7 . These chemicals are mixed together with water to form a clear aqueous solution that is environmentally-friendly (i.e. clean) non-toxic, but performs extremely well as a total fire inhibitor. In the presence of a flame, the chemical molecules in the CFIC-coating formed with Hartindo AF21 liquid on the surface of the fire-protected lumber, interferes with the free radicals (H+, OH−, O) involved in the free-radical chemical reactions within the combustion phase of a fire, and breaks these free-radical chemical reactions and extinguishes the fire&#39;s flames. 
     Specifying the Method of and System for Producing Class-A Fire-Protective Cross-Laminated Timber (CLT) Building Components According to the Present Invention 
       FIG. 8  shows a section of a three-ply Class-A fire-protected cross-laminated timber (CLT) panel produced in accordance with the principles of the present invention, offering 6 layers of Class-A fire-protection and defense against fire. Typically, Douglas Fir, Western Larch &amp; SPF Grade 2 are used to make CLT panels. Defects such as large knots and resin or bark pockets are removed from the timber used for the CLT production process, based on the strength and final visual quality. 
       FIG. 9  shows the flame spread and smoke development characteristics of Spruce Pine Fir (SPF) and Douglas Fir Class-A fire-protected lumber, after being dip-coated with clean fire inhibiting chemical (CFIC) liquid as generally shown in  FIGS. 10  and  10 A, and tested in accordance with ASTM E84 and UL 723 test standards. Based on these measured flame spread and smoke development indices for Spruce Pine Fir (SPF) and Douglas Fir Class-A fire-protected lumber, it is expected that CLT products of the present invention, when constructed using substantially the same kinds of lumber and treated in substantially the same manner using the CFIC liquid dip-coating methods disclosed in  FIGS. 10 and 10A  and described herein, will consistently produce flame spread index and smoke development index test results, entitling the CLT products according to the present invention to “Class-A fire-protected” status under ASTM E84 and UL 723 test standards. 
       FIG. 10  shows an automated factory system  30  for prefabricating mass timber buildings using Class-A fire-protected cross-laminated timber (CLT) products  49 ′ produced from production lines supported within the automated factory system. In the case of CLT panels, after the planning and dimensioning stage, the timber laminations are automatically dip-coated in clean fire inhibiting chemical (CFIC) liquid, then tunnel dried, and thereafter cross-stacked, glued, pressed and cured into Class-A fire-protected CLT panels  49 ′. The Class-A fire-protected CLT building components of the present invention can be used to build high-rise, low-rise, single apartment and multi-apartment mass timber buildings, in a manner well known in the art. 
     In accordance with the principles of the present invention, a three-ply Class-A fire-protected cross-laminated timber (CLT) panel  49 ′ bears six (6) surface coatings of clean fire inhibiting chemical (CFIC) liquid (e.g. Hartindo AF21 Total Fire Inhibitor). This set of CFIC surface coatings prevents flames from spreading by breaking the free radical chemical reaction within the combustion phase of fire, and confining the fire to the ignition source which can be readily extinguished, or go out by itself. When practicing the present invention, it is important that other fungicides, biocides, wood preservatives, and/or mildew agents are not added to the CFIC solution  37 H (i.e. Hartindo AF21) in the CFIC dip coating tank  37 B because it has been discovered that such agents will chemically interfere with and adversely effect the fire-inhibiting properties and characteristics of the Hartindo AF21 fire-inhibiting chemicals, proven by ASTM E84 flame spread test results. However, such agents can be added during the spray coating processes of the present invention, at the spray tunnel stage  43 , described in greater technical hereinbelow. 
     As shown in  FIG. 10 , the factory system  30  comprises a number of automated stages integrated together under automation and control, namely: a conveyor-chain transport mechanism  32  having various stages in the illustrative embodiment shown in  FIGS. 10A and 10B ; a controlled-drying stage  33  receiving short pieces of structural timber or lumber  31  from a supply warehouse maintained in or around the factory and drying them in a controlled manner well known in the art; a finger-jointing stage  34 , for processing short-length pieces of dried timber (i.e. lumber) and automatically fabricating extended-length finger-jointed pieces of timber, as output from this stage; a lamination planing stage  35  for planing finger-jointed pieces of timber (i.e. laminations) to produce finger-jointed timber laminations  36 ; an in-line CFIC liquid dip-coating stage  37 , as further detailed in  FIG. 10A , supporting an elongated dipping tank  37 B through which the chain-driven conveyor  32  transports the laminations  36  into the dipping tank  37 B and along its length while submerged under CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor)  37 K during dip-coating operations, to form a CFIC coating on the surfaces of the dip-coated laminations, and removing the CFIC-coated laminations from the dipping tank and transport it to the next stage along the production line; a drying tunnel stage  38 , for controllably drying the dip-coated laminations to a desired degree of moisture content; a cross-stacking and adhesive stage  39  for stacking timber laminations  36  and applying an adhesive coating to the finger-jointed timer laminations  36 ; a pressing and curing stage  40  where the stacked and glued finger-jointed laminations are stacked in a cross-directional manner, provided with adhesive coating, and then placed in a pressing machine where the adhesive is cured under pressure to produce a cross-laminated timber (CLT) panel, beam or other product; CNC trimming and fabrication stage  42  for trimming the cross-laminated timber (CLT) panels into CLT products  41 , and fabricating the CLT panels  49  to include apertures, and other interfaces and grooves formed therein; a spray tunnel  43  for spraying a clean fire inhibiting chemical (CFIC) liquid (with e.g. Hartindo AF21 or AF31), with polymer, mold/biocide and termite/DOT agents  44  over the surfaces of the worked CLT panel  49  to produce a coated CLT panel  49 ′ to be worked on by the CNC fabrication stage  42 ; a drying tunnel  45  for controllably drying the CLT panel to a particular moisture content (e.g. 12%+/−3%); a labeling stage  46  for applying a barcoded/RFID-tagged inspection checkpoint  47  to each CLT panel  49  produced on the production line; a packaging and wrapping stage  48  for packaging and wrapping CLT product  42 A; a chain-driven transport conveyor  32  for conveying the final barcoded/RFID-tagged CLT product  49 ′ along the next few stages of the production line. 
     As illustrated in  FIG. 10 , the controlled-drying stage  33  will include drying room with heaters that can be driven by electricity, natural or propane gas, or other combustible fuels which produce heat energy required to dry short-length lumber prior to the finger-joint wood processing stage. The boards are kiln dried to a moisture content of 12%+/−3%. Proper moisture content provides for proper adhesion and prevents dimensional variations and surface cracking. Some alternative embodiments, the controlled-drying stage  33  might be installed on the front end of the production line as shown in  FIG. 10 , and having input and output ports, with one stage of the conveyor-chain mechanism  32  passing through the heating chamber, from its input port to output port, allowing short-length lumber to be kiln-dried as it passes through the chamber along its conveyor mechanism. Other methods and apparatus can be used to realize this stage of the lumber production line of the present invention, provided that the desired degree of moisture within the wood is removed with heat or radiant energy at this stage of the process. 
     As illustrated in  FIG. 10 , the finger-jointing lumber processing stage  34  can be configured as generally disclosed in US Patent Application Publication Nos. US20070220825A1 and US20170138049A1, incorporated herein by reference. At this this finger jointing stage, boards are trimmed and finger jointed to obtain the desired lengths and quality of lumber. 
     In general, this stage involves robotic wood-working machinery, automation and programmable controls, well known in the finger-jointing wood art, and transforms multiple smaller-pieces of kiln-dried lumber into an extended-length piece of finger-jointed lumber, which is then planed and dimensioned during the next planning/dimensioning stage of the production line. An example of commercial equipment that may be adapted for the finger-jointing processing stage  34  may be the CRP 2500, CRP 2750 or CRP 3000 Finger Jointing System from Conception R.P., Inc., Quebec, Canada http://www.conceptionrp.com/finger-jointing-systems. 
     As illustrated in  FIG. 10 , the laminating planing stage  35  includes wood lamination planing equipment, such industrial band or rotary saws designed to cut, plane and dimension finger-jointed lumber pieces (i.e. laminations)  36  produced from the finger-jointing stage  34 , into finger-jointed timber laminations of a specified dimension and thickness. The lamination planing stage  35  can be realized using a band or radial saw as may be required to produce finger-jointed laminations. 
     As shown in  FIG. 10A , the CFIC liquid dip-coating stage  37  of the production line comprises a number of components integrated together, with suitable automation and controls, namely: a chain-driven conveyor subsystem  32  supporting several parallel sets of chain-driven transport rails  32 A 1 ,  32 A 2  and  32 A 3 , as shown, extending from the pressing and curing stage  40  towards a dipping tank  37 B, and then running inside and along the bottom of the dipping tank  37 B, and having the capacity of transporting finger-jointed timber laminations  36  having a length up to 30 or so feet. 
     In the illustrative embodiment, the dipping tank  37 B has a width dimension up to 32 or so feet to accommodate the width of the timber lamination  36  being transported on chain-driven conveyor rails  32 A 1 ,  32 A 2  and  32 A 3  mounted and running outside of and also within the dipping tank  37 B, as shown. As shown, the timber laminations  36  are supported upon the chain driven rails  32 A 1 ,  32 A 2  and  32 A 3  while the timber laminations  36  are transported through the dipping tank  37 B while fully immersed and submerged at least 6 inches deep in CFIC liquid  39 H contained in the dipping tank  37 B, moving lumber in and out of the dipping tank  39 B in just a few seconds during the CFIC dip-coating process of the present invention. Electrically-powered driven motors are provided for the purpose of driving the chain-driven conveyors  32 A 1 ,  32 A 2  and  32 A 3  under computer control to transport dip-coated timber laminations  36 ′ from stage to stage along the production line. A level sensor  37 F is used for real-time sensing and control of the liquid level of CFIC liquid  37 H in the dipping tank  37 B at any moment in time during production line operation. A reservoir tank  37 C is provided for containing a large volume or supply of made up CFIC liquid solution (e.g. Hartindo AF21 Total Fire Inhibitor). Also, a computer controller  37 G is used for controlling the conveyor subsystem  32 , and an electric pump  37 D for pumping CFIC liquid into the dipping tank  37 B to maintain a constant supply level during system operation in response to the liquid level measured by the level sensor  37 F and supplied to the control computer  37 G. 
     The dip-coating subsystem  37  may also include additional apparatus including, for example, liquid heaters, circulation pumps and controls for (i) maintaining the temperature of CFIC liquid solution in the dipping tank  37 B, and (ii) controlling the circulation of CFIC liquid around submerged timber  36  being transported through the dipping tank in a submerged manner during a CFIC coating process. Controlling such dip coating parameters may be used to control the amount and degree of absorption of CFIC liquid within the surface fibers of the CLT product, as it is rapidly transported through the dipping tank  37 B. Notably, the dip coating process allows for the rapid formation a surface coating, or surface barrier, on the surface of each piece of dipped timber  36 , and in the presence of a surfactant in the CFIC liquid in the dipping tank  37 B, shallow impregnation of CFIC liquid  37 H (e.g. Hartindo AF21) can occur into the surface fibers of each timber lamination  36  near atmospheric pressure (i.e. below 6 inches of liquid CFIC in the dipping tank  37 B). It is understood that drip pans may also be provided beyond the dipping tank  37 B, installed beneath the chain-driven conveyor subsystem  32  arranged between the dipping tank  37 B and the labeling and packaging stage  48 , so as to recover excess CFIC liquid dripping from the dip-coated lumber pieces and returning this recovered CFIC liquid to the dipping tank  37 B after appropriate filtering of the CFIC liquid if and as necessary. 
     As illustrated in  FIG. 10 , the stacking and adhesive application stage  39  can be realized using automated adhesive applicators well known in the art to apply a predetermined controlled amount of adhesive to each finger-jointed timber lamination  36  during the automated finger-jointing process. Each layer is sprayed with adhesive and the entire “sandwich” of stacked layers is then pressed vertically and horizontally in a large hydraulic press  40 . Typically, adhesives are waterproof and fire-resistant polyurethane; solvent-free and formaldehyde-free. 
     As illustrated in  FIG. 10 , the pressing and curing stage  40  can be realized using an automated pressing and curing machine well known in the art to apply a predetermined controlled amount of pressure to the timber laminations after they have been cross-configured, stacked, and placed into the machine for pressing and subsequent curing operations. 
     As illustrated in  FIG. 10 , fabricated assembled CLT panels  41  are cut to size, milled to spec, and finished as required using a Honegger CNC Panel Fabricator, or CNC bridge fabricator WMP240 by Weinmann, from Homag Machinery. The Honegger CNC Panel Fabricator supports a 4 head/5 axis CNC Fabricator capable of milling nearly any design specification.

Such technologies and machines can be used to implement many of the stages described above in the CLT panel production line of the present invention. https://www.ledinek.com/engineered-timber 
     As shown in  FIG. 10B , the fire, a blended liquid solution  43 B of fire-protection, moisture and UV protection, mold and termite agents is provided to the spray tunnel stage  43  deployed after CNC fabrication stage  42 . As shown, the spray tunnel stage  43  comprises: a storage tank  43 A for storing a large supply of moisture/fire/UV-protective liquid chemical  43 B; a spray tunnel  43 C for supporting an array of spray nozzles  43 D arranged about the conveyor rails, operably connected to a liquid pump  43 E connected to the storage tank  43 A under the controller  43 F, to provide a 360 degrees of spray coverage in the tunnel  43 , for spray-coating dip-coated CLT panels (e.g. elements) within a controlled plane of moisture/fire/UV-protection liquid sprayed to cover 100% of surfaces of such CLT panels  49  as they are being transported through the spray tunnel  43  at high-speed; and a drying tunnel stage  45  installed after the spray tunnel stage  43 , for quick drying of spray-coated Class-A fire-protected CLT panel  49 ′, as they move through the drying tunnel  45  towards the labeling and packaging stage  48  under the control of the controller  50 . In the preferred embodiment, the blended moisture/fire/UV/mold/termite protection liquid  43 B sprayed in the spray tunnel  43  is formulated as follows: 70% by volume Hartindo AF21 liquid (or Hartindo AF31); 10% by volume, polymer; 10% by volume, a biocide; and 10% by volume, termite agent, Disodium Octaborate Tetrahydrate (DOT). 
     As shown, the Class-A fire-protective CLT panels  49  are continuously feed through the spray tunnel stage  43  for spray coating a moisture/fire/UV-protective liquid coating over the entire surface as each dip-coated Class-A fire-protected CLT panel  49  is feed through the spray tunnel  43 . Then, the Class-A fire-protected CLT panel  49 ′ is quick-dried while being passed through the drying tunnel  45  disposed immediately after the spray tunnel  45 . This produces a Class-A fire-protective CLT product  49 ′ with a moisture/fire/UV/mold/termite protective coating as it exits the production line, improving the durability of the Class-A fire-protective CLT product when exposed to outdoor weather conditions during the construction phase. 
     In the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the Class-A fire-protected CLT panel interferes with the free radicals (H+, OH, O−) produced during the combustion phase of a fire, and breaks the fire&#39;s free-radical chemical reactions and extinguishes its flame. This is a primary fire suppression mechanism implemented by the CFIC-coatings deposited on wood surfaces in accordance with the principles of invention, disclosed and taught herein. 
     Method of Producing Class-A Fire-Protected Cross-Laminated Timber (CLT) Panels and Other Elements for Use in Class-A Fire-Protected Mass Timber Building Construction 
       FIGS. 11A, 11B and 11C  describe the high level steps carried out when practicing the method of producing Class-A fire-protected cross-laminated timber (CLT) panels  49 ′ for use in Class-A fire-protected mass timber building construction. 
     As indicated at Block A in  FIG. 11A , in an automated lumber factory, a high-speed Class-A fire-protected lumber production line is installed and operated, with a reservoir tank  37 B containing a large supply of clean fire inhibiting chemical (CFIC) liquid  37 H that is continuously supplied to the automated high-speed CFIC liquid dip-coating stage  37  of the lumber factory, installed before the adhesive application stage during CLT production in the factory. 
     As indicated at Block B in  FIG. 11A , a supply of untreated short-length lumber is loaded onto the conveyor-chain transport mechanism  32  installed along and between the stages of the production line. The term “short” is relative to the length of the timber product to be produced along the production line. 
     As indicated at Block C in  FIG. 11A , the untreated short-length lumber is loaded into the controlled-drying stage of the production line so to produce suitably dried short-length lumber for supply to the finger-jointing processing stage  34 . This stage can be performed by loading batches of short length lumber into the drying room or oven, whose temperature and humidity are strictly controlled using electric heaters and other equipment under computer control. Alternatively, short-length lumber pieces can be controllably dried by moving batches of short-length lumber through a drying tunnel-like chamber, through which chain-driven conveyor mechanism  32  passes, like other stages along the lumber production line of the present invention, while the temperature and humidity of the environment is controlled using electric-driven or gas-combusting space heaters under computer control in a manner well known in the art. The goal of this stage is to drive off moisture in the timber until it reaches 12% humidity, plus or minus 2% As indicated at Block D in  FIG. 11A , the controllably-dried short-length lumber is continuously supplied into the finger-jointing stage  34 , for producing pieces of extended-length finger-jointed timber (lumber)  36  in a highly automated manner. 
     As indicated at Block E in  FIG. 11B , pieces of extended length finger-jointed timber are planed and dimensioned into pieces of finger-jointed timber laminations  36 , and outputting the same onto the conveyor-chain transport mechanism  32 . 
     As indicated at Block F in  FIG. 11B , the planed and dimensioned finger-jointed timber laminations  36  are continuously transported and submerged through the dipping tank  37 B of the dip coating stage  37  for sufficient coating in CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor)  37 K, while being transported on the conveyor-chain transport mechanism  32 . 
     As indicated at Block G in  FIG. 11B , continuously removing the wet dip-coated timber lamination timber  36  as they are continuously removed from the dipping tank  39 B, and automatically move through the drying tunnel  38  at the subsequent stage along the production line. 
     In the illustrative embodiment, Hartindo AF21 Total Fire Inhibitor is used as the CFIC liquid solution  34 H to form the CFIC surface coating onto treated wood/lumber products produced on the production line of the factory described above. The surfactants in the Hartindo AF21 CFIC liquid enable its chemical molecules to impregnate ever so slightly the surface of the treated wood. This way, in the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the fire-protected lumber, interferes with the free radicals (H+, OH−, O−) of the chemical reaction produced within the combustion phase of a fire, and breaks the fire&#39;s chemical reaction and extinguishes its flame. This is a primary fire suppression mechanism deployed or rather implemented by the CFIC-coatings deposited on wood surfaces in accordance with the various principles of invention, disclosed and taught herein. 
     As indicated at Block H in  FIG. 11B , feeding the wet dip-coated Class-A fire protected timber laminations  36  through a drying tunnel  38  to rapidly dry dip-coated timber laminations  36  as they pass through, to produce Class-A fire-protected timber laminations  36 ′. 
     As indicated at Block I in  FIG. 11B , applying adhesive material to the Class-A fire-protected timber laminations  36 ′ produced during Block H, as they pass through the stacking and adhesive stage  39 , where the dip-coated timber laminations  36 ′ are cross-stacked according to cross-laminated stacking principles illustrated in  FIG. 2A , to form n layers of Class-A fire-protected timber laminations  36 ′ stacked together with applied adhesive on the laminations. 
     As indicated at Block J in  FIG. 11B , at the pressing &amp; curing stage  40 , pressing n-layers of Class-A fire-protected timber laminations  36 ′ together with applied adhesive on the laminations, and then curing the adhesively joined laminations to produce n-ply Class-A fire-protected cross-laminated timber (CLT) products  41 . 
     As indicated at Block K in  FIG. 11C , use CNC machining at CNC fabrication stage  42  to trim and form apertures in CLT panels  41  to produce fabricated Class-A fire-protected CLT panels  41 ′ with apertures, mounting holes, grooves and other surface features. 
     As indicated at Block L in  FIG. 11C , continuously feeding Class-A fire-protected CLT products through a spray coating tunnel  43 , spraying Class-A fire-protective CLT product  41  and depositing clean fire-inhibiting chemical (CFIC) liquid, and a moisture and UV (and optionally mold and termite) protection coating over the Class-A fire-protected CLT panels  41  while the CLT panel  41  is being passed through the spraying tunnel  43  in a high-speed manner. 
     As indicated at Block M in  FIG. 11C , continuously feeding the protective-coated Class-A fire-protected CLT products  44  through a drying tunnel  45  to rapidly dry the protective-coated Class-A fire-protected CLT products as they pass through the drying tunnel  45 . 
     As indicated at Block N in  FIG. 11C , labeling and packaging the Class-A fire-protective CLT products  49 ′ at the labeling and packaging stage  48 , and preparing for shipping to a destination. At the labeling stage  48 , a unique barcoded/RFID-tagged inspection checkpoint  300  is mounted on each Class-A fire-protective CLT products  49 ′ in a conspicuous manner, containing certifications of Class-A fire-protecting by CFIC liquid dip-coating and spray-coating operations, by particular technicians under particular supervisions, who certify as to the quality of services provided to the CLT building product/component  49 ′ on certain dates. Each barcoded/RFID-tag  182  will be encoded with an unique product identifier that relates to a mass timber building project, and customer, and identifies where all information for the CLT product  49 ′ is stored on the network database  113 C on the system network  135 . Such information on the barcode/RFID-tagged inspection checkpoint  300  will be uploaded and stored in the network database  113 A of the system network  135  to be described in greater detail hereinafter. 
     Specifying the Method of and System for Producing Class-A Fire-Protective Glue Laminated Timber (GLT) Building Components According to the Present Invention 
       FIG. 12  shows a section of a ten-ply (10-ply) Class-A fire-protected GLT beam produced in accordance with the principles of the present invention, offering 10 layers of Class-A fire-protection and defense against fire. Typically, Douglas Fir, Western Larch &amp; SPF Grade 2 are typically used for making GLT panels. Defects such as large knots and resin or bark pockets are removed from the timber used for the GLT production process, based on the strength and final visual quality. 
       FIG. 13  shows the flame spread and smoke development characteristics of Spruce Pine Fir (SPF) and Douglas Fir Class-A fire-protected lumber, after being dip-coated with clean fire inhibiting chemical (CFIC) liquid as generally shown in  FIGS. 14 and 14A , and tested in accordance with ASTM E84 and UL 723 test standards. Based on these measured flame spread and smoke development indices for Spruce Pine Fir (SPF) and Douglas Fir Class-A fire-protected lumber, it is expected that GLT products of the present invention, when constructed using substantially the same kinds of lumber and treated in substantially the same manner using the CFIC liquid dip-coating methods disclosed in  FIGS. 14 and 14A  and described herein, will consistently produce flame spread index and smoke development index test results, entitling the GLT products according to the present invention to “Class-A fire-protected” status under ASTM E84 and UL 723 test standards. 
       FIG. 14  shows an automated factory system  60  for prefabricating mass timber buildings using Class-A fire-protected glue-laminated timber (GLT) products  79 ′ produced from production lines supported within the automated factory system. In the case of GLT panels, after the planning and dimensioning stage, the timber laminations are automatically dip-coated in clean fire inhibiting chemical (CFIC) liquid, then tunnel dried, and thereafter stacked, glued, pressed and cured into Class-A fire-protected GLT beams, panels and other building products. The Class-A fire-protected GLT building components of the present invention  79 ′ can be used to build high-rise, low-rise, single apartment and multi-apartment mass timber buildings, in a manner well known in the art. 
     In accordance with the principles of the present invention, a ten-ply Class-A fire-protected glue laminated timber (GLT) panel  79 ′ bears ten (10) surface coatings of clean fire inhibiting chemical (CFIC) liquid (e.g. Hartindo AF21 Total Fire Inhibitor). This set of CFIC surface coatings prevents flames from spreading by breaking the free radical chemical reaction within the combustion phase of fire, and confining the fire to the ignition source which can be readily extinguished, or go out by itself. When practicing the present invention, it is important that other fungicides, biocides, wood preservatives, and/or mildew agents are not added to the CFIC solution  37 H (i.e. Hartindo AF21) in the CFIC dip coating tank  37 B because it has been discovered that such agents will chemically interfere with and adversely effect the fire-inhibiting properties and characteristics of the Hartindo AF21 fire-inhibiting chemicals, proven by ASTM E84 flame spread test results. However, such agents can be added during the spray coating processes of the present invention, at the spray tunnel stage  43 , described below. 
     As shown in  FIG. 14 , the factory  60  comprises a number of automated stages integrated together under automation and control, namely: a conveyor-chain transport mechanism  32  having various stages in the illustrative embodiment shown in  FIGS. 14A and 14B ; a controlled-drying stage  33  receiving short pieces of structural timber or lumber  31  from a supply warehouse maintained in or around the factory and drying them in a controlled manner well known in the art; a finger-jointing stage  34 , for processing short-length pieces of dried timber (i.e. lumber) and automatically fabricating extended-length finger-jointed pieces of timber, as output from this stage; a lamination planing stage  35  for planing finger-jointed pieces of timber (i.e. laminations) to produce finger-jointed timber laminations  36 ; an in-line CFIC liquid dip-coating stage  37 , as further detailed in  FIG. 14A , supporting an elongated dipping tank  37 B through which the chain-driven conveyor  32  transports the laminations  36  into the dipping tank  37 B and along its length while submerged under CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor)  37 K during dip-coating operations, to form a CFIC coating on the surfaces of the dip-coated laminations  36 ′, and removing the CFIC-coated laminations  36 ′ from the dipping tank and transport it to the next stage along the production line; a drying tunnel stage  38 , for controllably drying the dip-coated laminations  36 ′ to a desired degree of moisture content; an stacking and adhesive stage  39 ′ for stacking dip-coated finger-jointed timber laminations  36 ′ and applying an adhesive (e.g. glue) coating to the timer laminations  36 ′; a pressing and curing stage  40  where the stacked and glued finger-jointed laminations are stacked in a linear-directional (grains aligned) manner, provided with adhesive coating, and then placed in pressing machine where the adhesive is cured under pressure to produce a Class-A fire-protected glue-laminated timber (GLT) panel, beam or other product  79 ; a spray tunnel  43  for spraying a clean fire inhibiting chemical (CFIC) liquid (with blended polymer, and mold and terminate agents)  44  over the surfaces of the Class-A fire-protected GLT panel  79  to produce a coated Class-A fire-protected GLT panel  79 ′; a drying tunnel  45  for controllably drying the GLT panel to a particular moisture content (e.g. 12%+/−3%); a labeling and packaging stage  48  for applying a barcoded/RFID-tagged  300  to each Class-A fire-protected GLT panel  79 ′ produced on the production line; a chain-driven transport conveyor  32  for conveying the final barcoded/RFID-tagged GLT product  79 ′ along the next few stages of the production line. 
     As illustrated in  FIG. 14 , the controlled-drying stage  33  will include drying room with heaters that can be driven by electricity, natural or propane gas, or other combustible fuels which produce heat energy required to dry short-length lumber prior to the finger-joint wood processing stage. The boards are kiln dried to a moisture content of 12%+/−3%. Proper moisture content provides for proper adhesion and prevents dimensional variations and surface cracking. Some alternative embodiments, the controlled-drying stage  33  might be installed on the front end of the production line as shown in  FIG. 14 , and having input and output ports, with one stage of the conveyor-chain transport mechanism  32  passing through the heating chamber, from its input port to output port, allowing short-length lumber to be kiln-dried as it passes through the chamber along its conveyor mechanism. Other methods and apparatus can be used to realize this stage of the lumber production line of the present invention, provided that the desired degree of moisture within the wood is removed with heat or radiant energy at this stage of the process. 
     As illustrated in  FIG. 14 , the finger-jointing lumber processing stage  34  can be configured as generally disclosed in US Patent Application Publication Nos. US20070220825A1 and US20170138049A1, incorporated herein by reference. At this this finger jointing stage, boards are trimmed and finger jointed to obtain the desired lengths and quality of lumber. 
     In general, this stage involves robotic wood-working machinery, automation and programmable controls, well known in the finger-jointing wood art, and transforms multiple smaller-pieces of kiln-dried lumber into an extended-length piece of finger-jointed lumber, which is then planed and dimensioned during the next planning/dimensioning stage of the production line. An example of commercial equipment that may be adapted for the finger-jointing processing stage  34  may be the CRP 2500, CRP 2750 or CRP 3000 Finger Jointing System from Conception R.P., Inc., Quebec, Canada http://www.conceptionrp.com/finger-jointing-systems. 
     As illustrated in  FIG. 14 , the laminating planing stage  35  includes wood lamination planing equipment, such industrial band or rotary saws designed to cut, plane and dimension finger-jointed lumber pieces produced from the finger-jointing stage  34 , into finger-jointed timber laminations of a specified dimension and thickness. The lamination planing stage  35  can be realized using a band or radial saw as may be required to produce finger-jointed laminations. 
     As shown in  FIG. 14A , the CFIC liquid dip-coating stage  37  of the production line comprises a number of components integrated together, with suitable automation and controls, namely: a chain-driven conveyor subsystem  32  supporting several parallel sets of chain-driven transport rails  32 A 1 ,  32 A 2  and  32 A 3 , as shown, extending from the pressing and curing stage  40  towards a dipping tank  37 B, and then running inside and along the bottom of the dipping tank  37 B, and having the capacity of transporting finger-jointed timber laminations  36  having a length up to 30 or so feet. 
     In the illustrative embodiment, the dipping tank  37 B has a width dimension of 32 or so feet to accommodate the width of the timber laminations  36  being transported on chain-driven conveyor rails  32 A 1 ,  32 A 2  and  32 A 3  mounted and running outside of and also within the dipping tank  37 B, as shown. As shown, the timber laminations  36  are supported upon the chain driven rails  32 A 1 ,  32 A 2  and  32 A 3  while the timber laminations  36  are transported through the dipping tank  37 B while fully immersed and submerged at least 6 inches deep in CFIC liquid  37 H contained in the dipping tank  37 B, moving lumber in and out of the dipping tank  37 B in just a few seconds during the CFIC dip-coating process of the present invention. Electrically-powered driven motors are provided for the purpose of driving the chain-driven conveyors  32 A 1 ,  32 A 2  and  32 A 3  under computer control to transport timber laminations  36  from stage to stage along the production line. A level sensor  37 F is used for real-time sensing and control of the liquid level of CFIC liquid  37 H in the dipping tank  37 B at any moment in time during production line operation. A reservoir tank  37 C is provided for containing a large volume or supply of made up CFIC liquid solution (e.g. Hartindo AF21 Total Fire Inhibitor). Also, a computer controller  37 G is used for controlling the conveyor subsystem  32 , and an electric pump  37 D for pumping CFIC liquid into the dipping tank  37 B to maintain a constant supply level during system operation in response to the liquid level measured by the level sensor  37 F and supplied to the control computer  37 G. 
     The dip-coating subsystem  37  may also include additional apparatus including, for example, liquid heaters, circulation pumps and controls for (i) maintaining the temperature of CFIC liquid solution in the dipping tank  37 B, and (ii) controlling the circulation of CFIC liquid around submerged timber  36  being transported through the dipping tank in a submerged manner during a CFIC coating process. Controlling such dip coating parameters may be used to control the amount and degree of absorption of CFIC liquid within the surface fibers of the timber laminations  36 , as it is rapidly transported through the dipping tank  37 B. Notably, the dip coating process allows for the rapid formation a surface coating, or surface barrier, on the surface of each piece of dipped timber  36 , and in the presence of a surfactant in the CFIC liquid in the dipping tank  37 B, shallow impregnation of CFIC liquid  37 H (e.g. Hartindo AF21) can occur into the surface fibers of each timber lamination  36  near atmospheric pressure (i.e. below 6 inches of liquid CFIC in the dipping tank  37 B). It is understood that drip pans may also be provided beyond the dipping tank  37 B, installed beneath the chain-driven conveyor subsystem  32  arranged between the dipping tank  37 B and the labeling and packaging stage  48 , so as to recover excess CFIC liquid dripping from the dip-coated lumber pieces and returning this recovered CFIC liquid to the dipping tank  37 B after appropriate filtering of the CFIC liquid if and as necessary. 
     As illustrated in  FIG. 14 , the stacking and adhesive application stage  39 ′ can be realized using automated adhesive applicators well known in the art to apply a predetermined controlled amount of adhesive to each finger-jointed timber lamination  36  during the automated finger-jointing process. Each layer is sprayed with adhesive and the entire “sandwich” of stacked layers is then pressed vertically and horizontally in a large hydraulic press  40 . Typically, adhesives are waterproof and fire-resistant polyurethane; solvent-free and formaldehyde-free. 
     As illustrated in  FIG. 14 , the pressing and curing stage  40  can be realized using an automated pressing and curing machine well known in the art to apply a predetermined controlled amount of pressure to the timber laminations  36  after they have been stacked and placed into the machine for pressing and subsequent curing operations. 
     LEDINEK Engineering, do.o.o, of Hoce, Slovenia, offers complete turnkey production lines that can be modified for high-volume automated production of glue-laminated timber (GLT) beams. Such systems comprise: lamination planers; finger jointing machines; presses &amp; curing machines; and automation and controllers. Such technologies and machines can be used to implement many of the stages described above in the GLT panel production line of the present invention. 
     As shown in  FIG. 14B , the fire, moisture and UV protection, mold and termite agents is provided using the spray tunnel stage  43  deployed after the drying stage  38 . As shown, the spray tunnel stage  43  comprises: a storage tank  43 A for storing a large supply of moisture/fire/UV-protective liquid chemical  43 B; a spray tunnel  43 C for supporting an array of spray nozzles  43 D arranged about the conveyor rails, operably connected to a liquid pump  43 E connected to the storage tank  43 A under the controller, to provide a 360 degrees of spray coverage in the tunnel  43 , for spray-coating dip-coated GLT panels (e.g. elements)  79  within a controlled plane of moisture/fire/UV-protection liquid sprayed to cover 100% of surfaces of such GLT panel  79  as they are being transported through the spray tunnel  43  at high-speed; and a drying tunnel stage  45  installed after the spray tunnel stage  43 , for quick drying of spray-coated Class-A fire-protected GLT panel  79 ′, as they move through the drying tunnel  45  towards the labeling and packaging stage  48  under the control of the controller. In the preferred embodiment, the moisture/fire/UV protection liquid  43 B sprayed in the spray tunnel  43  is formulated as follows: 70% by volume Hartindo AF21 liquid (or Hartindo AF31 liquid); 10% by volume, polymer; 10% by volume, a biocide; and 10% by volume, termite agent, Disodium Octaborate Tetrahydrate (DOT). 
     As shown, the Class-A fire-protective GLT panels  79  are continuously feed through the spray tunnel stage  43  for spray coating a moisture/fire/UV-protective liquid coating  43 B over the entire surface as each Class-A fire-protected GLT panel  79  is feed through the spray tunnel  43 . Then, the Class-A fire-protected GLT panel  41  is quick-dried while being passed through the drying tunnel  45  disposed immediately after the spray tunnel  45 . This produces a Class-A fire-protective GLT product  79 ′ with a moisture//fire/UV protective coating as it exits the production line, improving the durability of the Class-A fire-protective GLT product  79 ′ when exposed to outdoor weather conditions during the construction phase. 
     In the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the Class-A fire-protected GLT panel interferes with the free radicals (H+, OH−, O−) produced during the combustion phase of a fire, and breaks the fire&#39;s free-radical chemical reactions and extinguishes its flame. This is a primary fire suppression mechanism implemented by the CFIC-coatings deposited on wood surfaces in accordance with the principles of invention, disclosed and taught herein. 
     Method of Producing Class-A Fire-Protected Glue-Laminated Timber (GLT) Panels and Other Elements for Use in Fire-Protected Mass Timber Building Construction 
       FIGS. 15A, 15B and 15C  describe the high level steps carried out when practicing the method of producing Class-A fire-protected glue-laminated timber (GLT) panels  79 ′ for use in Class-A fire-protected mass timber building construction. 
     As indicated at Block A in  FIG. 15A , in an automated lumber factory, a high-speed Class-A fire-protected lumber production line is installed and operated, with a reservoir tank  37 B containing a large supply of clean fire inhibiting chemical (CFIC) liquid  37 H that is continuously supplied to the automated high-speed CFIC liquid dip-coating stage  37  of the lumber factory, installed before the adhesive application stage during GLT production in the factory. 
     As indicated at Block B in  FIG. 15A , a supply of untreated short-length lumber is loaded onto the conveyor-chain transport mechanism  32  installed along and between the stages of the production line. The term “short” is relative to the length of the timber product to be produced along the production line. 
     As indicated at Block C in  FIG. 15A , the untreated short-length lumber is loaded into the controlled-drying stage of the production line so to produce suitably dried short-length lumber for supply to the finger-jointing processing stage  34 . This stage can be performed by loading batches of short length lumber into the drying room or oven, whose temperature and humidity are strictly controlled using electric heaters and other equipment under computer control. Alternatively, short-length lumber pieces can be controllably dried by moving batches of short-length lumber through a drying tunnel-like chamber, through which chain-driven conveyor mechanism  32  passes, like other stages along the lumber production line of the present invention, while the temperature and humidity of the environment is controlled using electric-driven or gas-combusting space heaters under computer control in a manner well known in the art. The goal of this stage is to drive off moisture in the timber until it reaches 12% humidity, plus or minus 2%. 
     As indicated at Block D in  FIG. 15A , the controllably-dried short-length lumber is continuously supplied into the finger-jointing stage  34 , for producing pieces of extended-length finger-jointed timber laminations (lumber pieces)  36  in a highly automated manner. 
     As indicated at Block E in  FIG. 15B , pieces of extended length finger-jointed timber are planed and dimensioned into pieces of finger-jointed timber laminations  36 , and outputting the same onto the conveyor-chain transport mechanism  32 . 
     As indicated at Block F in  FIG. 15B , the planed and dimensioned finger-jointed timber laminations  36  are continuously transported and submerged through the dipping tank  37 B of the dip coating stage  37  for sufficient coating in CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor)  37 H, while being transported on the conveyor-chain transport mechanism  32 . 
     As indicated at Block G in  FIG. 15B , continuously removing the wet dip-coated timber laminations  36  are continuously removed from the dipping tank  39 B. 
     In the illustrative embodiment, Hartindo AF21 Total Fire Inhibitor is used as the CFIC liquid solution  34 H to form the CFIC surface coating onto treated wood/lumber products produced on the production line of the factory described above. The surfactant in the Hartindo AF21 CFIC liquid enables its chemical molecules to break the surface tension and allow chemical molecules to impregnate ever so slightly the surface of the treated wood. This way, in the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the fire-protected lumber, interferes with the free radicals (H+, OH−, O−) of the chemical reaction produced within the combustion phase of a fire, and breaks the fire&#39;s chemical reaction and extinguishes its flame. This is a primary fire suppression mechanism deployed or rather implemented by the CFIC-coatings deposited on wood surfaces in accordance with the various principles of invention, disclosed and taught herein. 
     As indicated at Block H in  FIG. 15B , the wet dip-coated Class-A fire protected timber laminations  36  are continuously feed through a drying tunnel  38  to rapidly dry dip-coated timber laminations  36  as they pass through, to produce Class-A fire-protected timber laminations  36 ′. 
     As indicated at Block I in  FIG. 15B , adhesive material is applied to the Class-A fire-protected timber laminations  36 ′ produced during Block H, as they pass through the stacking and adhesive stage  39 . 
     As indicated at Block J in  FIG. 15B , n-layers of Class-A fire-protected timber laminations  36 ′ are stacked together, in an end-to-end manner, with applied adhesive on the laminations, and then the stack is pressed together and cured to produce n-ply Class-A fire-protected glue-laminated timber (GLT) products  79 . 
     As indicated at Block K in  FIG. 15C , the Class-A fire-protected CLT products  79  are continuously feed through a spray coating tunnel  43 , spraying Class-A fire-protective GLT product  79  and depositing clean fire-inhibiting chemical (CFIC) liquid, and a moisture and UV protection coating over the Class-A fire-protected GLT panels  79  while the GLT panel is being passed through the spraying tunnel  43  in a high-speed manner. 
     As indicated at Block L in  FIG. 15C , the protective-coated Class-A fire-protected GLT products  79 ′ is continuously feed through a drying tunnel  45  to rapidly dry the protective-coated Class-A fire-protected GLT products  79 ′ as they pass through the drying tunnel  45 . 
     As indicated at Block M in  FIG. 15C , the Class-A fire-protective CLT products  79 ′ are labeled and packaged at the labeling and packaging stage  48 , and prepared for shipping to a destination. At the labeling stage  48 , a unique barcoded/RFID-tagged inspection checkpoint  300  is mounted on each Class-A fire-protective GLT products  79 ′ in a conspicuous manner, containing certifications of Class-A fire-protecting by CFIC liquid dip-coating and spray-coating operations, by particular technicians under particular supervisions, who certify as to the quality of services provided to the CLT building product/component  79 ′ on certain dates. Each barcoded/RFID-tag will encoded an unique product identifier that relates to a mass timber building project, and the customer, and identifies where all information for the Class-A fire-protected GLT product  79 ′ is stored on the network database  113 C on the system network  135 . Such information encoded at the barcode/RFID-tagged inspection checkpoint  300  will be uploaded and stored in the network database  113 A of the system network  135  to be described in greater detail hereinafter. 
     Specifying the Method of and System for Producing Class-A Fire-Protective Nail-Laminated Timber (NLT) Building Components According to the Present Invention 
       FIG. 16  shows a section of multi-ply Class-A fire-protected NLT panel  89 ′ produced in accordance with the principles of the present invention, offering 6 layers of Class-A fire-protection and defense against fire. Typically, Douglas Fir, Western Larch &amp; SPF Grade 2 are typically used for making Class-A fire-protected NLT panels  89 ′. Defects such as large knots and resin or bark pockets are removed from the timber used for the NLT production process, based on the strength and final visual quality. 
       FIG. 17  shows the flame spread and smoke development characteristics of Spruce Pine Fir (SPF) and Douglas Fir Class-A fire-protected lumber, after being dip-coated with clean fire inhibiting chemical (CFIC) liquid as generally shown in  FIGS. 10 and 10A , and tested in accordance with ASTM E84 and UL 723 test standards. Based on these measured flame spread and smoke development indices for Spruce Pine Fir (SPF) and Douglas Fir Class-A fire-protected lumber, it is expected that NLT products of the present invention, when constructed using substantially the same kinds of lumber and treated in substantially the same manner using the CFIC liquid dip-coating methods disclosed in  FIGS. 18 and 18A  and described herein, will consistently produce flame spread index and smoke development index test results, entitling the NLT products according to the present invention to “Class-A fire-protected” status under ASTM E84 and UL 723 test standards. 
       FIG. 18  shows an automated factory system  80  for prefabricating mass timber buildings using Class-A fire-protected nail-laminated timber (NLT) products  89 ′ produced from production lines supported within the automated factory system. In the case of NLT panels, after the planning and dimensioning stage, the timber laminations are automatically dip-coated in clean fire inhibiting chemical (CFIC) liquid, then tunnel dried, and thereafter stacked and nailed into Class-A fire-protected NLT panels. The Class-A fire-protected NLT building components of the present invention can be used to build high-rise, low-rise, single apartment and multi-apartment mass timber buildings, in a manner well known in the art. 
     In accordance with the principles of the present invention, a multi-ply Class-A fire-protected nail-laminated timber (NLT) panel  89 ′ bears multiple surface coatings of clean fire inhibiting chemical (CFIC) liquid (e.g. Hartindo AF21 Total Fire Inhibitor). This set of CFIC surface coatings prevents flames from spreading by breaking the free radical chemical reaction within the combustion phase of fire, and confining the fire to the ignition source which can be readily extinguished, or go out by itself. When practicing the present invention, it is important that other fungicides, biocides, wood preservatives, and/or mildew agents are not added to the CFIC solution  37 H (i.e. Hartindo AF21) in the CFIC dip coating tank  37 B because it has been discovered that such agents will chemically interfere with and adversely effect the fire-inhibiting properties and characteristics of the Hartindo AF21 fire-inhibiting chemicals, proven by ASTM E84 flame spread test results. However, such agents can be added during the spray coating processes of the present invention, at the spray tunnel stage  43 , described in greater detail below. 
       FIG. 18  shows an automated factory system  80  for producing Class-A fire-protected nail-laminated timber (NLT) panels, beams, and other products in a high volume manner. As shown in  FIG. 18 , the factory  80  comprises a number of automated stages integrated together under automation and control, namely: a multi-stage conveyor-chain mechanism  32  having numerous primary stages in the illustrative embodiment shown in  FIGS. 18A and 18B ; a controlled-drying stage  33  receiving short pieces of structural timber or lumber  31  from a supply warehouse maintained in or around the factory and drying them in a controlled manner well known in the art (e.g. Douglas Fir, Western Larch &amp; SPF Grade 2 is typically used for making CLT panels); a finger-jointing stage  34 , for processing short-length pieces of dried timber (i.e. lumber) and automatically fabricating extended-length finger-jointed pieces of timber, as output from this stage; a lamination planing stage  35  for planing finger-jointed pieces of timber (i.e. laminations) to produce finger-jointed timber laminations  36 ; an in-line CFIC liquid dip-coating stage  37 , as further detailed in  FIG. 18A , supporting an elongated dipping tank  37 B through which the chain-driven conveyor  32  transports the laminations  36  into the dipping tank  37 B and along its length while submerged under CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor)  37 K during dip-coating operations, to form a CFIC coating on the surfaces of the dip-coated laminations, and removing the CFIC-coated laminations from the dipping tank and transport it to the next stage along the production line; a drying tunnel stage  38 , for controllably drying the dip-coated laminations to a desired degree of moisture content; a stacking and nailing stage  39 ″ for stacking timber laminations and driving nails into the finger-jointed timer laminations  36 ′ to produce a nail-laminated timber (NLT) panel, beam or other product  89 ; a spray tunnel  43  for spraying a clean fire inhibiting chemical (CFIC) liquid (blended with liquid polymer, and mold/biocide and termite/DOT agents)  44  over the surfaces of the Class-A fire-protected NLT panel  89  to produce a spray-coated Class-A fire-protected NLT panel  89 ′; a drying tunnel  45  for controllably drying the Class-A fire-protected NLT panel  89 ′ to a particular moisture content (e.g. 12%+/−3%); and a labeling and package stage  46  for applying a barcoded/RFID-tagged  300  to each Class-A fire-protected NLT panel  89 ′ produced on the production line. 
     As illustrated in  FIG. 18 , the controlled-drying stage  33  will include drying room with heaters that can be driven by electricity, natural or propane gas, or other combustible fuels which produce heat energy required to dry short-length lumber prior to the finger-joint wood processing stage. The boards are kiln dried to a moisture content of 12%+/−3%. Proper moisture content provides for proper adhesion and prevents dimensional variations and surface cracking. Some alternative embodiments, the controlled-drying stage  33  might be installed on the front end of the production line as shown in  FIG. 18 , and having input and output ports, with one stage of the conveyor-chain mechanism  32  passing through the heating chamber, from its input port to output port, allowing short-length lumber to be kiln-dried as it passes through the chamber along its conveyor mechanism. Other methods and apparatus can be used to realize this stage of the lumber production line of the present invention, provided that the desired degree of moisture within the wood is removed with heat or radiant energy at this stage of the process. 
     As illustrated in  FIG. 18 , the finger-jointing lumber processing stage  34  can be configured as generally disclosed in US Patent Application Publication Nos. US20070220825A1 and US20170138049A1, incorporated herein by reference. At this this finger jointing stage, boards are trimmed and finger jointed to obtain the desired lengths and quality of lumber. 
     In general, this stage involves robotic wood-working machinery, automation and programmable controls, well known in the finger-jointing wood art, and transforms multiple smaller-pieces of kiln-dried lumber into an extended-length piece of finger-jointed lumber, which is then planed and dimensioned during the next planning/dimensioning stage of the production line. An example of commercial equipment that may be adapted for the finger-jointing processing stage  34  may be the CRP 2500, CRP 2750 or CRP 3000 Finger Jointing System from Conception R.P., Inc., Quebec, Canada http://www.conceptionrp.com/finger-jointing-systems. 
     As illustrated in  FIG. 18 , the laminating planing stage  35  includes wood lamination planing equipment, such industrial band or rotary saws designed to cut, plane and dimension finger-jointed lumber pieces produced from the finger-jointing stage  34 , into finger-jointed timber laminations of a specified dimension and thickness. The lamination planing stage  35  can be realized using a band or radial saw as may be required to produce finger-jointed laminations. 
     As shown in  FIG. 18A , the CFIC liquid dip-coating stage  37  of the production line comprises a number of components integrated together, with suitable automation and controls, namely: a chain-driven conveyor subsystem  32  supporting several parallel sets of chain-driven transport rails  32 A 1 ,  32 A 2  and  32 A 3 , as shown, extending towards a dipping tank  37 B, and then running inside and along the bottom of the dipping tank  37 B, and having the capacity of transporting finger-jointed timber laminations  36  having a length up to 30 or so feet. 
     In the illustrative embodiment, the dipping tank  37 B has a width dimension of 32 or so feet to accommodate the width of the finger-jointed timber laminations  36  being transported on chain-driven conveyor rails  32 A 1 ,  32 A 2  and  32 A 3  mounted and running outside of and also within the dipping tank  37 B, as shown. As shown, the timber laminations  36  are supported upon the chain driven rails  32 A 1 ,  32 A 2  and  32 A 3  while the timber laminations  36  are transported through the dipping tank  37 B while fully immersed and submerged at least 6 inches deep in CFIC liquid  37 H contained in the dipping tank  37 B, moving lumber in and out of the dipping tank  39 B in just a few seconds during the CFIC dip-coating process of the present invention. Electrically-powered driven motors are provided for the purpose of driving the chain-driven conveyors  32 A 1 ,  32 A 2  and  32 A 3  under computer control to transport timber laminations  36  from stage to stage along the production line. A level sensor  37 F is used for real-time sensing and control of the liquid level of CFIC liquid  37 H in the dipping tank  37 B at any moment in time during production line operation. A reservoir tank  37 C is provided for containing a large volume or supply of made up CFIC liquid solution (e.g. Hartindo AF21 Total Fire Inhibitor). Also, a computer controller  37 G is used for controlling the conveyor subsystem  32 , and an electric pump  37 D for pumping CFIC liquid into the dipping tank  37 B to maintain a constant supply level during system operation in response to the liquid level measured by the level sensor  37 F and supplied to the control computer  37 G. 
     The dip-coating subsystem  37  may also include additional apparatus including, for example, liquid heaters, circulation pumps and controls for (i) maintaining the temperature of CFIC liquid solution in the dipping tank  37 B, and (ii) controlling the circulation of CFIC liquid around submerged timber  36  being transported through the dipping tank in a submerged manner during a CFIC coating process. Controlling such dip coating parameters may be used to control the amount and degree of absorption of CFIC liquid within the surface fibers of the finger-jointed timber laminations  36 , as it is rapidly transported through the dipping tank  37 B. Notably, the dip coating process allows for the rapid formation a surface coating, or surface barrier, on the surface of each piece of dipped timber  36 , and in the presence of a surfactant in the CFIC liquid in the dipping tank  37 B, shallow impregnation of CFIC liquid  37 H (e.g. Hartindo AF21) can occur into the surface fibers of each timber lamination  36  near atmospheric pressure (i.e. below 6 inches of liquid CFIC in the dipping tank  37 B). It is understood that drip pans may also be provided beyond the dipping tank  37 B, installed beneath the chain-driven conveyor subsystem  32  arranged between the dipping tank  37 B and the labeling and packaging stage  48 , so as to recover excess CFIC liquid dripping from the dip-coated lumber pieces and returning this recovered CFIC liquid to the dipping tank  37 B after appropriate filtering of the CFIC liquid if and as necessary. 
     As illustrated in  FIG. 18 , the stacking and nailing stage  39 ″ can be realized using automated nail gun system well known in the art. 
     LEDINEK Engineering, do.o.o, of Hoce, Slovenia, offers complete turnkey production lines which can be modified for high-volume automated production of nail-laminated timber (NLT) panels. Such systems comprise: lamination planers; finger jointing machines; and automation and controllers. Such technologies and machines can be used to implement many of the stages described above in the NLT beam production line of the present invention. 
     As shown in  FIG. 18B , the fire, moisture and UV protection, mold and termite agents is provided using the spray tunnel stage  43  deployed after the drying stage  38 . As shown, the spray tunnel stage  43  comprises: a storage tank  43 A for storing a large supply of blended moisture/fire/UV-protective liquid chemical  43 B; a spray tunnel  43 C for supporting an array of spray nozzles  43 D arranged about the conveyor rails, operably connected to a liquid pump  43 E connected to the storage tank  43 A under the controller, to provide a 360 degrees of spray coverage in the tunnel  43 , for spray-coating Class-A fire-protected panels (e.g. elements)  89  within a controlled plane of moisture/fire/UV-protection liquid sprayed to cover 100% of the surfaces as they are being transported through the spray tunnel  43  at high-speed; and a drying tunnel stage  45  installed after the spray tunnel stage  43 , for quick drying of spray-coated Class-A fire-protected NLT panel  89 ′, as they move through the drying tunnel  45  towards the labeling and packaging stage  48  under the control of the controller  50 . In the preferred embodiment, the moisture/fire/UV protection liquid  43 B sprayed in the spray tunnel  43  is formulated as follows: 70% by volume Hartindo AF21 liquid (or Hartindo AF31 liquid); 10% by volume, polymer; 10% by volume, a biocide; and 10% by volume, termite agent, Disodium Octaborate Tetrahydrate (DOT). 
     As shown, the Class-A fire-protective CLT panels  89  are continuously feed through the spray tunnel stage  43  for spray coating a moisture/fire/UV-protective liquid coating  43 B over the entire surface as each Class-A fire-protected NLT beam or panel  89  is feed through the spray tunnel  43 . Then, the Class-A fire-protected NLT beam  89 ′ is quick-dried while being passed through the drying tunnel  45  disposed immediately after the spray tunnel  45 . This produces a Class-A fire-protective NLT product ′ 89  with a moisture/fire/UV protective coating as it exits the production line, improving the durability of the Class-A fire-protective NLT product when exposed to outdoor weather conditions during the construction phase. 
     In the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the Class-A fire-protected NLT panel  89 ′ interferes with the free radicals (H+, OH−, O−) produced during the combustion phase of a fire, and breaks the fire&#39;s free-radical chemical reactions and extinguishes its flame. This is a primary fire suppression mechanism implemented by the CFIC-coatings deposited on wood surfaces in accordance with the principles of invention, disclosed and taught herein. 
     Method of Producing Class-A Fire-Protected Nail-Laminated Timber (NLT) Panels and Other Elements for Use in Class-A Fire-Protected Mass Timber Building Construction 
       FIGS. 19A, 19B and 19C  describe the high level steps carried out when practicing the method of producing Class-A fire-protected nail-laminated timber (NLT) panels  89 ′ for use in Class-A fire-protected mass timber building construction. 
     As indicated at Block A in  FIG. 19A , in an automated lumber factory, a high-speed Class-A fire-protected lumber production line is installed and operated, with a reservoir tank  37 B containing a large supply of clean fire inhibiting chemical (CFIC) liquid  37 H that is continuously supplied to the automated high-speed CFIC liquid dip-coating stage  37  of the lumber factory, installed before the stacking and nailing stage  39 ″ during NLT production in the factory. 
     As indicated at Block B in  FIG. 19A , a supply of untreated short-length lumber is loaded onto the conveyor-chain transport mechanism  32  installed along and between the stages of the production line. The term “short” is relative to the length of the timber product to be produced along the production line. 
     As indicated at Block C in  FIG. 19A , the untreated short-length lumber is loaded into the controlled-drying stage of the production line so to produce suitably dried short-length lumber for supply to the finger-jointing processing stage  34 . This stage can be performed by loading batches of short length lumber into the drying room or oven, whose temperature and humidity are strictly controlled using electric heaters and other equipment under computer control. Alternatively, short-length lumber pieces can be controllably dried by moving batches of short-length lumber through a drying tunnel-like chamber, through which chain-driven conveyor mechanism  32  passes, like other stages along the lumber production line of the present invention, while the temperature and humidity of the environment is controlled using electric-driven or gas-combusting space heaters under computer control in a manner well known in the art. The goal of this stage is to drive off moisture in the timber until it reaches 12% humidity, plus or minus 2% As indicated at Block D in  FIG. 19A , the controllably-dried short-length lumber is continuously supplied into the finger-jointing stage  34 , for producing pieces of extended-length finger-jointed timber (lumber)  36  in a highly automated manner. 
     As indicated at Block E in  FIG. 19B , pieces of extended length finger-jointed timber are planed and dimensioned into pieces of finger-jointed timber laminations  36 , and outputting the same onto the conveyor-chain transport mechanism  32 . 
     As indicated at Block F in  FIG. 19B , the planed and dimensioned finger-jointed timber laminations  36  are continuously transported and submerged through the dipping tank  37 B of the dip coating stage  37  for sufficient coating in CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor)  37 H, while being transported on the conveyor-chain transport mechanism  32 . 
     As indicated at Block G in  FIG. 19B , continuously removing the wet dip-coated timber laminations  36 ′ are continuously removed from the dipping tank  39 B, and automatically move through the drying tunnel  38  at the subsequent stage along the production line. 
     In the illustrative embodiment, Hartindo AF21 Total Fire Inhibitor is used as the CFIC liquid solution  37 H to form the CFIC surface coating onto treated wood/lumber products produced on the production line of the factory described above. The surfactants in the Hartindo AF21 CFIC liquid helps to break the surface tension and allow its chemical molecules to impregnate ever so slightly the surface of the treated wood. This way, in the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the fire-protected lumber, interferes with the free radicals (H+, OH−, O−) of the chemical reaction produced within the combustion phase of a fire, and breaks the fire&#39;s chemical reaction and extinguishes its flame. This is a primary fire suppression mechanism deployed or rather implemented by the CFIC-coatings deposited on wood surfaces in accordance with the various principles of invention, disclosed and taught herein. 
     As indicated at Block H in  FIG. 19B , feeding the wet dip-coated Class-A fire protected timber laminations  36  through a drying tunnel  38  to rapidly dry dip-coated timber laminations  36  as they pass through, to produce Class-A fire-protected timber laminations  36 ′. 
     As indicated at Block I in  FIG. 19B , n-layers of Class-A fire-protected timber laminations  36  are stacked and automatically nailed together with nails driven between the lamination  36 , to produce n-ply Class-A fire-protected nail-laminated timber (NLT) products  89 . 
     As indicated at Block J in  FIG. 19B , the Class-A fire-protected NLT products  89  are continuously feed through a spray coating tunnel  43  and coated with clean fire-inhibiting chemical (CFIC) liquid and a moisture and UV protection coating (and optionally mold/biocide and termite/DOT) agents) over the Class-A fire-protected NLT products  89 ′. 
     As indicated at Block K in  FIG. 19C , the protective-coated Class-A fire-protected NLT products  89 ′ are continuously feed through a drying tunnel  45  to rapidly dry the protective-coated Class-A fire-protected NLT products  89 ′ as they pass through the drying tunnel  45 . 
     As indicated at Block L in  FIG. 19C , the Class-A fire-protective NLT products  89 ′ are labeled and packaged at the labeling and packaging stage  48 , and prepared for shipping to a destination. 
     At the labeling stage  48 , a unique barcoded/RFID-tagged inspection checkpoint  300  is mounted on each Class-A fire-protective NLT products  89 ′ in a conspicuous manner, containing certifications of Class-A fire-protecting by CFIC liquid dip-coating and spray-coating operations, by particular technicians under particular supervisions, who certify as to the quality of services provided to the NLT building product/component  89 ′ on certain dates. Each barcoded/RFID-tag will be encoded a unique product identifier that relates to a mass timber building project, and the customer, and identifies where all information for the NLT product  89 ′ is stored on the network database  113 C on the system network  135 . Such information on the barcode/RFID-tagged inspection checkpoint  300  will be uploaded and stored in the network database  113 A of the system network  135  to be described in greater detail hereinafter.

The system  101  includes a spray nozzle assembly  101 D that connected to the spray pump  101 C by way of a flexible  101 E for use in spraying CFIC liquid over wood surfaces of a mass timber building. 
     As shown in  FIG. 23B , the GPS-tracked mobile anti-fire liquid spraying system  101  of  FIG. 23A  comprises a number of subcomponents, namely: a GPS-tracked and remotely-monitored CFIC liquid spray control subsystem  101 F; a micro-computing platform or subsystem  101 G interfaced with the GPS-tracked and remotely-monitored AF chemical liquid spray control subsystem  101 F by way of a system bus  101 I; and a wireless communication subsystem  101 H interfaced to the micro-computing platform  101 G via the system bus  201 . As configured, the GPS-tracked mobile CFIC liquid spraying system  2101  enables and supports (i) the remote monitoring of the spraying of CFIC liquid from the system  101  when located at specific GPS-indexed location coordinates, and (ii) the logging of all such GPS-indexed spray application operations, and recording the data transactions thereof within a local database maintained within the micro-computing platform  101 G, as well as in the remote network database  9 C 1  maintained at the data center  110  of the system network  109 .

     In the preferred embodiment, the CFIC liquid is preferably Hartindo AF31 Total Fire Inhibitor, developed by Hartindo Chemicatama Industri of Jakarta, Indonesia, and commercially-available from Newstar Chemicals (M) SDN. BHD of Selangor Darul Ehsan, Malaysia, http://newstarchemicals.com/products.html. When so treated, combustible products will prevent flames from spreading, and confine fire to the ignition source which can be readily extinguished, or go out by itself. In the presence of a flame, the chemical molecules in both dry and wet coatings, formed with Hartindo AF31 liquid, interferes with the free radicals (H+, OH−, O) involved in the free-radical chemical reactions within the combustion phase of a fire, and breaks these free-radical chemical reactions and extinguishes the fire&#39;s flames. 
     In general, any commercially-grade airless liquid spraying system may be used and adapted to construct the GPS-tracked mobile system  101  for spraying Class-A fire-protective liquid coatings on mass timber building construction sites, and practice the method and system of the present invention, with excellent results. Many different kinds of commercial spray coating systems may be used to practice the present invention, and each may employ an electric motor or air-compressor to drive its liquid pump. For purposes of illustration only, the following commercial spray systems are identified as follows: the Xtreme XL™ Electric Airless Spray System available from Graco, Inc. of Minneapolis, Minn.; and the Binks MX412 Air-Assisted/Compressor-Driven Airless Spray System from Carlisle Fluid Technologies, of Scottsdale, Ariz. 
     Countless on-site locations will exist having various sizes and configurations requiring the on-job-site spray-based fire-protection method of the present invention.  FIG. 24A  illustrates a first job-site of multi-apartment mass timber building under construction which has undergone clean fire inhibiting chemical spray coating treatment in accordance with the principles of the present invention.  FIG. 24B  illustrates a second job-site of multi-apartment mass timber building under construction which has undergone clean fire inhibiting chemical spray coating treatment in accordance with the principles of the present invention. 
     The on-job-site spray method and system involves spraying a clean fire inhibiting chemical (CFIC) liquid on all new construction lumber and sheathing to prevent fire ignition and flame spread. The method also recommends spraying exterior walls or the exterior face of the roof, wall and floor sheathing with CFIC liquid. The method further recommends that factory-applied fire-protective lumber be used on exterior walls, and fire-protected sheathing be used on the exterior face of the roof, wall and floor sheathing, as it offers extra UV and moisture protection. As disclosed herein, there are many different options available to architects and builders to meet such requirements within the scope and spirit of the present invention disclosed herein. 
     In the illustrative embodiment, Hartindo AF31 Total Fire Inhibitor (from Hartindo Chemicatama Industri of Jakarta, Indonesia http://hartindo.co.id, or its distributor Newstar Chemicals of Malaysia) is used as the CFIC liquid  101 C to spray-deposit the CFIC surface coating onto treated wood/lumber and sheathing products inside the mass timber building under construction. A liquid dye of a preferred color from Sun Chemical Corporation http://www.sunchemical.com can be added to Hartindo AF31 liquid to help the spray technicians visually track where CFIC liquid has been sprayed on wood surfaces during the method of treatment. The clinging agent in this CFIC liquid formulation (i.e. Hartindo AF31 liquid) enables its chemical molecules to cling to the surface of the CFIC-coated wood so that it is quick to defend and break the combustion phase of fires (i.e. interfere with the free radicals driving combustion) during construction and before drywall and sprinklers can offer any defense against fire. However, a polymer liquid binder, available from many manufacturers (e.g. BASF, Polycarb, Inc.) can be added as additional cling agent to Hartindo AF31 liquid, in a proportion of 1-10% by volume to 99-90% Hartindo AF31 liquid, so as to improve the cling factor of the CFIC liquid when being sprayed in high humidity job-site environments. Alternatively, liquid DecTan Chemical from Hartindo Chemicatama Industri, which contains a mixture of vinyl acrylic copolymer and tannic acid, can be used a cling agent as well when mixed the same proportions, as well as an additional UV and moisture defense on exterior applications. These proportions can be adjusted as required to achieve the cling factor required in any given building environment where the spray coating method of the present invention is being practiced. This way, in the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the fire-protected lumber, interfere with the chemical reactions involving the free radicals (H+, OH−, O−) produced during the combustion phase of a fire, and break the fire&#39;s chemical reaction and extinguish its flame. This is a primary fire suppression mechanism deployed or rather implemented by the CFIC-coatings deposited on wood surfaces in accordance with the various principles of invention, disclosed and taught herein. 
     Specification of Method of Producing Multi-Story Mass Timber Buildings Having Class-A Fire-Protection and Improved Resistance Against Fire Destruction 
       FIGS. 25A, 25B and 25C , taken together, set forth a high-level for chart describing the steps carried out when practicing the method of producing multi-story mass timber buildings having improved fire resistance rating and protection against fire destruction. The method comprises a series of steps described below which effectively results in the coating of substantially all exposed interior wood surfaces of the raw untreated as well as fire-treated lumber and sheathing used during the construction phase of the mass timber building, to protect and defend its wood, lumber and sheathing from ravage of fire and prevent total destruction by fire. The method recommends use of the Class-A fire-protected mass timber building components shown and described herein for use in mass timber building structures. 
     The spray-coating fire-treatment process of the present invention may be carried out as follows. Spray-coating technicians (i) appear on the new construction job-site after each floor (i.e. mass timber building section) has been constructed with wood framing and sheathing; (ii) spray liquid CFIC solution over substantially all of the exposed interior surfaces of the wood, lumber and sheathing used in the completed mass timber building section; and then (iii) certify that each such mass timber building section has been properly spray-coat protected with CFIC liquid chemicals in accordance with the principles of the present invention. Details of this method will be described in greater detail below in a step-by-step manner. 
     As indicated at Block A in  FIG. 25A , the first step of the method involves fire-protection spray-coating technician to receives a request from a builder to spray a clean fire inhibiting chemical (CFIC) liquid coating over substantially all exposed interior surfaces of the untreated and/or treated wood lumber and sheathing used to construct a completed wood-framed section of a building under construction at a particular site location. This order could come in the form of a written work order, and email message, or other form of communication, with appropriate documentation. 
     As indicated at Block B in  FIG. 25A , the second step of the method involves the fire-protection spray-coating technician (i) receiving building construction specifications from the builder, architect and/or building owner, (ii) analyzing same to determine the square footage of clean fire inhibiting chemical (CFIC) liquid coating to be spray applied to the interior surfaces of the wood-frame building, (iii) computing the quantity of clean fire inhibiting chemical material required to do the spray job satisfactorily, and (iv) generating a price quote for the spray job and sending the quote to the builder for review and approval. 
     As indicated at Block C in  FIG. 25A , the third step of the method involves, after the builder accepts the price quote, the builder orders the clean fire-protection spray team to begin performing the on-site wood coating spray job in accordance with the building construction schedule. 
     As indicated at Block D in  FIG. 25A , the fourth step of the method involves, after the builder completes each completed section of wood framing with wood sheathing installed, but before any wallboard has been installed, the spray technician (i) procures a supply of clean fire-protection chemicals (CFIC) liquid solution, (ii) fills the reservoir tank of an airless liquid spraying system with the supply of CFIC liquid, and (iii) then uses a spray gun to spray CFIC liquid in the reservoir tank, over all exposed interior wood surfaces of the completed section of the mass timber building under construction.  FIGS. 49 and 50  show an air-less liquid spraying system  101  for spraying CFIC liquid over all exposed interior surfaces of lumber and wood sheathing used in a completed section of the mass timber building under construction, so as to form a Class-A fire-protective coating over such treated surfaces. 
     As indicated at Block A in  FIG. 25C , the first stage of this step involves procuring water-based CFIC liquid for on-job-site spray-treatment of raw untreated and treated lumber and sheathing used inside a mass timber building. In the preferred embodiment, Hartindo AF31 from Hartindo Chemicatama Industri (and available from its distributor Newstar Chemical of Malaysia) is used as the CFIC liquid employed by the method of the present invention. Hartindo AF31 CFIC is an environmentally-friendly water-based, biodegradable and non-toxic solution that is non-ozone depleting and does not require cleanup procedures after usage. Hartindo AF31 CFIC is also effective for all classes of fires: involving solid, carbonaceous materials; flammable fuels, thinners, etc.; gas, electricity fires, and energy fires; and metal fire and oxidizing fires. 
     As indicated at Block B in  FIG. 25C , the second stage of this step involves filling the tank of the air-less liquid spraying system  101  with the procured supply of CFIC liquid. 
     As indicated at Block C in  FIG. 25C , the third stage of this step involves using the spray nozzle gun  103  of the air-less liquid spraying system  101  as shown in  FIGS. 16 and 17 , to a spray apply a uniform coating of liquid clean fire inhibiting chemical (CFIC) liquid over all of the interior surfaces of the completed section of mass timber building being spray treated during the construction phase of the building, in accordance with the principles of the present invention. In the illustrative embodiment, the liquid CIFC (i.e. Hartindo AF31) is applied at a rate (i.e. coating coverage density) of about 590 square feet per gallon, although it is understood that this rate may vary from illustrative embodiment, to illustrative embodiment. 
     The CFIC liquid used in the present invention clings to the wood on which it is sprayed, and its molecules combine with the (H+, OH−, O−) free radicals in the presence of fire, during combustion, to eliminate this leg of the fire triangle so that fire cannot exist in the presence of such a CFIC based coating. 
       FIGS. 24A and 24B  shows a few illustrative examples of building construction job site locations where the spray-based fire protective method of the present invention might be practiced with excellent results. It is understood that such examples are merely illustrative, and no way limiting with regard to the present invention. 
     As indicated at Block E in  FIG. 25B , during the fifth step of the method, when the completed section of the building has been spray coated with clean fire inhibiting chemical (CFIC) liquid, the completed building section is certified and marked as certified for visual inspection and insurance documentation purposes, preferably using barcoded/RFID-tagged inspection checkpoints  300  shown in  FIGS. 24A, 24B, 36 and 37 , and the system network  100  described in  FIGS. 28 through 38 . 
     Alternatively, such marking of completed sprayed building sections can involving posting a spray-coating checkboard, with a seal or certificate using an indelible ink, with date, job ID #, sprayer #, and other information related to specific spray-coat fire-protection job that have been certified as a completed at that mass timber building section. Preferably, the architectural plans for the building, as well as building schematics used on the job site, will have building section identification numbers or codes, which will be used on the certificate of completion stamped onto the spray-coated fire-protected sheathing and lumber on the job site. Typically, the on-job-site spray project information sheet will contain numerous basic information items, including, for example: Date; Customer Name; Weather Description and Temperature; Building Address; Customer Address: Customer Supervisor; Units of Part of the Building Sprayed; Sprayer Used; Spray Technician Supervisor; and Notes. 
     As part of the certification process, an on-job-site spray project information sheet is maintained in the network database system  113 A, supported on the system network  100 , using the system network  100  and mobile application  120  described in  FIGS. 28 through 38 . Photographic and video recordings can also be made and stored in a database as part of the certification program, as will be described in greater detail below. 
     As indicated at Block F in  FIG. 25B , during sixth step of the method, as each section of the mass timber building is constructed according to the construction schedule, the spray coating team continues to spray coat the completed section, and certify and mark as certified each such completed spray coated section of the building under construction, using barcoded/RFID-tagged inspection checkpoints  300 , shown in  FIGS. 24A, 24B, 36 and 37 , and the system network  100  described in  FIGS. 28 through 38 . 
     As indicated at Block G in  FIG. 25B , during the seventh step of the method, when all sections of the building under construction have been completely spray coated with clean fire inhibiting chemical (CFIC) materials, suppressing fire ignition and suppression by capturing free radicals (H+, OH−, O−) during the combustion phase, and certified as such, the spray technicians remove the spray equipment from the building, and the builder proceeds to the next stages of construction and completes the building construction according to architectural and building plans and specifications. 
     As indicated at Block H in  FIG. 25B , during the eighth step of the method, the spray technician then issues a certificate of completion with respect to the application of clean fire-protection chemicals to all exposed wood surfaces on the interior of the mass timber building during its construction phase, thereby protecting the building from risk of total destruction by fire. Preferably, the certificate of completion should bear the seal and signature of a professional engineer (PE) and the building architect who have been overseeing and inspecting the building construction project. 
       FIG. 27  shows the flame spread and smoke development characteristics of Spruce Pine Fir (SPF) and Douglas Fir species of Class-A fire-protected lumber, after being spray-coated with clean fire inhibiting chemical (CFIC) liquid as generally shown in  FIGS. 22A and 22B , and tested in accordance with ASTM E84 and UL 723 test standards. Based on these measured flame spread and smoke development indices for Spruce Pine Fir (SPF) and Douglas Fir species of lumber, it is expected that on-site sprayed mass timber surfaces, when constructed using substantially the same kinds of lumber and treated in substantially the same manner using the CFIC liquid dip-coating methods disclosed in  FIGS. 22A and 22B  and described herein, will consistently produce flame spread index and smoke development index test results that will entitle CFIC-liquid sprayed mass timber surfaces (e.g. associated CLT, GLT and NLT products) to “Class-A fire-protected” status under ASTM E84 and UL 723 test standards. 
     Advantages and Benefits of the On-Job-Site Method of Mass Timber Treatment and Fire-Protection by Way of Spray Coating of CFIC Liquid Over the Surface of Exposed Interior and Exterior Wood Used in Mass Timber Buildings 
     The on-site spray coating method of the present invention described above involves the use of CFIC liquid having the property of clinging onto the surface of the wood to which it is applied during on-job-site spray-coating operations, and then inhibiting the ignition of a fire and its progression by interfering with the free-radicals (H+, OH−, O−) involved in the combustion phase of any fire. Hartindo AF31 liquid fire inhibitor meets these design requirements. 
     In general, CFIC liquids that may be used to practice the on-site fire-protection method of the present invention suppresses fire by breaking free radical (H+, OH−, O−) chemical reactions occurring within the combustion phase of fire, quickly and effectively suppressing fire in a most effective manner, while satisfying strict design requirements during the construction phase of a mass timber building construction project. At the same time, the spray-based method of wood treatment and fire-protection will not degrade the strength of the wood materials (i.e. Modulus of Elasticity (MOE) and the Modulus of Rupture (MOR)) when treated with the CFIC-based liquid spray chemicals applied during the method of treatment. 
     The on-site wood lumber/sheathing spraying method of the present invention overcomes the many problems associated with pressure-treated fire retardant treated (FRT) lumber, namely: “acid hydrolysis” also known as “acid catalyzed dehydration” caused by FRT chemicals; significant losses in the Modulus of Elasticity (MOE), the Modulus of Rupture (MOR) and impact resistance of pressure-treated wood. 
     Internet-Based Cloud-Based System for Verifying and Documenting Class-A Fire-Protection Treatment of a Wood-Framed Building Using On-Site Spraying of a Clean Fire Inhibiting Chemical (CFIC) Liquid 
       FIG. 28  shows Internet-based (i.e. cloud-based) system  100  for verifying and documenting Class-A fire-protection treatment of a mass timber building using on-site spraying of a clean fire inhibiting chemical (CFIC) liquid, as described in  FIGS. 49 through 54 , comprising: (i) a data center  110  with web servers  111 , application servers  112  and database servers  113 , with SMS servers  114  and email message servers  115 , each operably connected to the TCP/IP infrastructure  114  of the Internet  116  for supporting a web-based site for hosting images/videos of certificates of completion  119  stamped or printed on spray-treated wood surfaces, at registered inspection checkpoints, often with other certification documents; and (ii) mobile computing systems  117  ( 117 A,  117 B,  117 C) (e.g. smart-phones such as the Apple iPhone and Samsung Android phone) with either a mobile application  120  installed, and a web-browser application, as discussed further hereinafter. 
     In the preferred embodiment, each mobile computing system  117  is configured for: (i) capturing digital photographs and video recordings of completed spray-treated wood-framed sections with barcoded/RFID-tagged certificates of inspection  300  posted in buildings under construction  118  ( 118 A,  118 B,  118 C), as illustrated in  FIGS. 51A and 51B , upon completion of the on-site fire-protection spray process at specific building sections; (ii) recording notes and averments by the spray technicians who applied the CFIC liquid spray and supervisors who supervised the same; and (iii) uploading such time-date-stamped digital audio-video (AV) recordings and  121  to the servers  111 ,  112 ,  113  in the data center  110 , providing documented evidence of barcoded/RFID-tagged certificates of inspection (at inspection checkpoints)  300  stamped/printed or otherwise posted on the surfaces of sprayed wood surfaces, for each fire-protection spray-treatment project, so that insurance companies, builders, and other stakeholders (who are registered users of the system) can access and review such on-site spray completion certifications during and after the construction phase of a mass timber building, for various purposes. 
     As shown in  FIG. 28 , the system network  100  also includes a GPS satellite system  170  for transmitting GPS reference signals transmitted from a constellation of GPS satellites deployed in orbit around the Earth, to GPS transceivers installed aboard each GPS-tracking mobile image capturing and computing system  117 , as part of the illustrative embodiments. From the GPS signals it receives, each GPS transceiver is capable of computing in real-time the GPS location of its host system, in terms of longitude and latitude. In the case of the Empire State Building in NYC, N.Y., its GPS location is specified as: N40° 44.9064′, W073° 59.0735′; and in number only format, as: 40.748440, −73.984559, with the first number indicating latitude, and the second number representing longitude (the minus sign indicates “west”). 
       FIG. 29A  shows the mobile client computing system  117  ( 117 A,  117 B,  117 C) deployed on the system network  100  shown in  FIG. 28 , supporting the mobile application  120  installed on each mobile computing system  117 . The purpose of the mobile application  120  is to provide the mobile computing system  117  with a convenient tool for tracking and managing projects involving on-site clean fire inhibiting chemical (CFIC) liquid spray treatment of mass timber buildings during the construction phase, and the logistics associated therewith, to ensure the provision of Class-A fire-protection of all exposed interior wood surfaces in the mass timber building. All stakeholders (e.g. building owners, architects, builders, property insurance underwriters, local fire departments and firemen, and others such as project coordinators, spray technicians, site superintendents, site spray managers and others who are involved in the logistics, management and application of CFIC liquid spray onto and over all exposed interior surfaces of the building) will benefit from the system network  100  and its deployed mobile application  120 , and the services it supports across the enterprise. 
     Using the custom-designed mobile application  120 , property/building owners, architects, builders, insurance companies and other stakeholders can (i) track the progress being made while a mass timber building is being spray-treated with CFIC liquid during the construction project schedule, and (ii) review all collected pdf documents, digital images and audio-video recordings collected as visual evidence of “certificates of completion” by trained personnel, at predetermined inspection checkpoints in the mass timber building, during the course of the construction project. 
     The purpose of such digital evidence, collected on-site at each inspection checkpoint and remotely stored in the network database  113 A, is to verify and document proper application of CFIC liquid spray to each indexed inspection checkpoint designated at the commencement of the Project, and located throughout the interior of the mass timber building to ensure that 100% of all exposed interior surfaces within the mass timber building have been provided with Class-A fire-protection. 
     Preferably, each inspection checkpoint  300  will be identified by Project ID # with a unique coding to identify the Building #, Floor #, Section #, and optionally Panel # at which the inspection checkpoint is located, and where certificates of completion (for the specified section) will be stamped, signed and AV-recorded, and actual wood samples sprayed with CFIC liquid at the time of the certified spray application are AV-recorded and collected and archived for verification and documentation purposes. The AV-recording of certifications made at each registered inspection checkpoint  300  in the mass timber building should help to ensure that Class-A fire-protected wood-samples will be available in the future in the event there might be a need to investigate the Class-A fire-protection spray treatment process.

     In general, the system network  100  will be realized as an industrial-strength, carrier-class Internet-based network of object-oriented system design, deployed over a global data packet-switched communication network comprising numerous computing systems and networking components, as shown. As such, the information network of the present invention is often referred to herein as the “system” or “system network”. The Internet-based system network  100  can be implemented using any object-oriented integrated development environment (IDE) such as for example: the Java Platform, Enterprise Edition, or Java EE (formerly J2EE); Websphere IDE by IBM; Weblogic IDE by BEA; a non-Java IDE such as Microsoft&#39;s .NET IDE; or other suitably configured development and deployment environment well known in the art. Preferably, although not necessary, the entire system of the present invention would be designed according to object-oriented systems engineering (OOSE) methods using UML-based modeling tools such as ROSE by Rational Software, Inc. using an industry-standard Rational Unified Process (RUP) or Enterprise Unified Process (EUP), both well known in the art.

       FIG. 29A  shows the mobile computing system  117  ( 117 A,  117 B,  117 C) used in the system network  100  shown in  FIG. 28 , supporting the mobile application  120  installed on each registered mobile computing system  117 . The purpose of the mobile application  120  is to provide a convenient tool for tracking and managing projects involving on-site clean fire inhibiting chemical (CFIC) liquid spray treatment of mass timber buildings during the construction phase, to ensure Class-A fire-protection of the interior exposed wood surfaces of the building.

The memory interface  202 , the one or more processors  204  and/or the peripherals interface  206  can be separate components or can be integrated in one or more integrated circuits. The various components in the mobile device can be coupled by one or more communication buses or signal lines. Sensors, devices, and subsystems can be coupled to the peripherals interface  206  to facilitate multiple functionalities. For example, a motion sensor  210 , a light sensor  212 , and a proximity sensor  214  can be coupled to the peripherals interface  206  to facilitate the orientation, lighting, and proximity functions. Other sensors  216  can also be connected to the peripherals interface  206 , such as a positioning system (e.g. GPS receiver), a temperature sensor, a biometric sensor, a gyroscope, or other sensing device, to facilitate related functionalities. A camera subsystem  220  and an optical sensor  222 , e.g. a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, can be utilized to facilitate camera functions, such as recording photographs and video clips. Communication functions can be facilitated through one or more wireless communication subsystems  224 , which can include radio frequency receivers and transmitters and/or optical (e.g. infrared) receivers and transmitters. The specific design and implementation of the communication subsystem  224  can depend on the communication network(s) over which the mobile device is intended to operate. For example, the mobile device  117  may include communication subsystems  224  designed to operate over a GSM network, a GPRS network, an EDGE network, a Wi-Fi or WiMax network, and a Bluetooth™ network. In particular, the wireless communication subsystems  224  may include hosting protocols such that the device  117  may be configured as a base station for other wireless devices.

The one or more buttons (not shown) can include an up/down button for volume control of the speaker  228  and/or the microphone  230 . Such buttons and controls can be implemented as a hardware objects, or touch-screen graphical interface objects, touched and controlled by the system user. Additional features of mobile smartphone device  117  can be found in U.S. Pat. No. 8,631,358 incorporated herein by reference in its entirety. 
     Specification of Network Database Supported on the System Network of the Present Invention 
       FIG. 30  shows an exemplary schema  124  for the network database  113 A supported by the system network  100  shown in  FIG. 28 . Each primary enterprise object is schematically represented as an object in the schema and represented in the data records created and maintained in the network database. As shown, the schema  124  includes objects such as, for example: Users of the system (e.g. property owners, builders, spray technicians, insurance companies, etc); Real Property; Orders For On-Site Class-A Fire-Protection Liquid Spray Treatment; Clean Fire Inhibiting Chemical (CFIC) Liquid Supplies; Construction Project; and Mobile CFIC Liquid Spraying Systems. Each of these objects have further attributes specified by other sub-objects indicated in  FIG. 30 . 
     Using Mobile Computing Devices Deployed on the System Network to Verify and Document CFIC Liquid Spray Certifications Made at Each Barcoded/RFID-Tagged Inspection Checkpoint Specified Throughout the Mass Timber Building being Spray-Treated to Provide Class-A Fire Protection 
       FIG. 31  shows a schematic map indicating the bar-coded/RFID-tagged inspection checkpoints  300  assigned to specific locations throughout a mass timber building, by a spray project administrator, prior to the commencement of a project requiring the spraying of all interior wood surfaces thereof with CFIC liquid so as to provide Class-A fire-protection thereto. In this example, the building has two floors, and each floor has several sections requiring spray-treatment with CFIC liquid, to provide Class-A fire-protection, in accordance with the principles of the present invention. 
     In general, this map will be created at the commencement of each project for a specified mass timber building under construction, and its data structure will be stored in the network database  113 A for the created project, to enable the organized capture of barcoded/RFID-tagged certifications  300 , verifications and related documentation after spraying each completed mass timber section of the building under construction. 
     Each section of the mass timber building will be provided with at least one GPS-specified barcoded/RFID-tagged inspection checkpoint  300  (e.g. bearing certificates of spraying and inspection by spray technicians and site supervisors printed on a thin flexible plastic sheet, on which a barcode symbol/RFID-tag are mounted) indicated at  300  on the map. The map should clearly show the building/floor/section-specific locations of the barcoded/RFID-tagged inspection checkpoints  300 , shown in  FIGS. 24A, 24B and 36 , on the floor plan of the mass timber building, where the bar-coded/RFID-tagged inspection checkpoints  300  will be mounted on spray-treated wood surfaces, at the completion of spray-treating each section of the mass timber building, and subsequently signed by the spray technician and spray supervisor, and possibly the building site superintendent, and thereafter digitally photographed and video-recorded with the individuals involved in each such event being verified and documented using the system network of the present invention  100  and its deployed mobile applications  120 . 
     At each barcoded/RFID-tagged inspection checkpoint  300 , the spray technician and/or site supervisor uses his mobile computing device  117  to read the bar code symbol and/or RFID tag at the inspection checkpoint, to automatically (or semi-automatically) open the project storage location on the network database  113 A, and then capture and record digital images and AV-recordings of signed spray certifications and verifications by the spray technicians and/or site supervisor, and upload them to the network database  113 A using the mobile computing device  117  and mobile application  120 , in the case where native mobile applications have been deployed. The mobile application  120  will also capture the GPS coordinates of the mobile computing device  117 , and enter these coordinates into the project file/folder in the network database  113 A, for verification purposes. The mobile application  120  can also capture the IP address of the user&#39;s mobile computing device (e.g. Apple iPhone) and record such address information as well. Preferably, at each barcoded inspection checkpoint  300 , a set of four bar-coded Class-A fire-protect test boards  301 , and a pair of bar-coded UV-protected storage sleeve  302 A and  302 B, each adapted to store two test boards  301  after CFIC liquid has been spray thereupon to impart Class-A fire protection. One set of sprayed test sample boards will be provided to the building owner, or its professional engineer, to be held in custody for evidentiary purposes. The other set will go to spray contracting firm, typically its laboratory, for post-spray testing purposes, and also to hold for custodial reasons. Digital images of these spray-treated test boards  301  should also be captured and uploaded to the network database  113 A in the project folder under the specific inspection checkpoint at which the sprayed test samples where made, at a specific time and date, and GPS-location. Thereafter, these sprayed test boards  301  can be stored in their respective bar-coded storage sleeves  302 A,  302 B and provided to their respective parties. After such sprayed test samples have been made, and documented, it may desired for the spray contracting firm to send its sprayed test boards  301  to a scientific and engineering laboratory and conduct some tests to ensure that the highest possible scientific and engineering standards have been attained during the on-site spray treatment process, associated with each and every on-site mass timber building fire-protection spray process. Laboratory technicians may also use the mobile application  120  and system network  100  to add any information they might have regarding the their testing of sprayed test boards  301  produced at each barcoded inspection checkpoint in the project. 
     Once all certifications and verifications have been made by the spray technician and his site supervisor, and digital photographic and AV-recording documentation (i.e. evidence) has been captured and uploaded to the network database  113 A under the building-specific project, at a GPS-specified/barcoded inspection checkpoint  300 , the spray technician will resume spraying other sections of the mass timber building requiring spray treatment with CFIC liquid. 
     When using the system network of the present invention  100 , each certification and verification made by the spray technician and site supervisor at the barcoded inspection checkpoint, and captured and recorded in the network database  113 A using the user&#39;s mobile computing device  117  (e.g. Apple iPad), should include a legal declaration that a specific CFIC liquid formulation (e.g. Hartindo AF31 anti-fire liquid) has been applied to the sprayed wood surfaces of the completed section of this specific mass timber building at a particular time and date, and in an active concentration sprayed onto the wood surfaces so as to provide the sprayed wood surfaces with Class-A fire-protected characteristics, as independently tested by a particular licensed engineering testing organization, which should be identified and incorporated therein by reference.

     Specification of Method of Verifying and Documenting On-Site Spray-Applied Class-A Fire-Protection Over Mass Timber Buildings During Construction Using the On-Site Wood-Frame CFIC Liquid Spraying System 
       FIGS. 34A and 34B  describe a method of verifying and documenting on-site spray-applied Class-A fire-protection over mass timber buildings during construction using the on-site wood-frame CFIC liquid spraying system  100  shown in  FIGS. 22A through 23C . A description of this method is appropriate at this juncture. 
     As indicated at Block A in  FIG. 34A , after a builder completes each predetermined section of a mass timber building where wood-framing has been constructed and (plywood or OSB) sheathing installed, but before any wallboard has been installed, the spray technician uses an airless liquid spraying system  101  filled with clean fire inhibiting chemical (CFIC) liquid to spray the CFIC liquid over all exposed interior wood surfaces in the completed section of the mass timber building. 
     As indicated at Block B in  FIG. 34A , when the completed section of the mass timber building is spray coated with CFIC liquid, the completed mass timber building section is certified and marked as certified, with a barcoded/RFID-tagged inspection checkpoint  300  (with certificates of spraying and inspection) mounted at checkpoint locations in the completed section of the building, then certified and verified with signatures by the spray applicator and on-site spray supervisor manager (and optionally building site superintendent), and digitally documented by scanning and data capturing photos and/or audio-video recordings of the signed inspection checkpoints/events  300 , as shown in  FIGS. 24A and 24B  and  FIG. 36 , and using the mobile application  120  for uploading the captured documents to the barcoded-project folder in the network database  113 A on the system network  100 , for subsequent visual inspection and insurance documentation purposes, as shown  FIG. 28 . 
     As indicated at Block C in  FIG. 34A , as each section of the mass timber building is constructed according to the construction schedule, the spray coating team continues to spray coat the completed section with CFIC liquid (e.g. Hartindo AF31), and certify and mark, using barcoded/RFID-tagged certificates of inspection (at inspection checkpoints)  300 , each such completed spray coated section  118  ( 118 A,  118 B,  118 C) of the building under construction. 
     As indicated at Block D in  FIG. 34B , when the spray project is completed, the spray technician and supervisor then issue a time/date stamped “certificate of completion” certifying that clean fire inhibiting chemical (CFIC) liquid spray has been applied to all exposed interior wood surfaces on the interior of the mass timber building during its construction phase, thereby providing the sprayed mass timber building with Class-A fire-protection and defense against risk of total destruction by fire. 
     As indicated at Block E in  FIG. 34B , before applying gypsum board and/or other wall board covering over the fire-protected spray-coated mass timber building section  118 , the mobile application  120  on mobile computing device  117  is used to capture and collect digital photographs and/or videos showing certificates of inspection at inspection checkpoints  300  posted on spray-coated fire-protected sheathing and/or lumber used in the wood framing of each completed building section, as visual evidence and job-site completion documentation, required or desired by insurance companies and/or government building departments and/or safety agencies. Preferably, each completed section of the mass timber building should be assigned a section number by the builder, and if not by the builder, then by the spray application administrator, so that each certificate of completion, stamped on the wood surface of each section of the mass timber building, and signed and dated by the on-site CFIC liquid spray applicator and on-site manager, will be digitally captured as images and/or AV recordings, and then uploaded to the system network database under the project ID number for project verification and documentation purposes. 
     As indicated at Block F in  FIG. 34B , uploading captured digital photographs and videos collected during Block E to the centralized network database  113 A on the system network  100 , maintained by the fire-protection spray coating technician company, or its agent, as a valued-added service provided for the benefit of the property/building owner, builder, architect, home-owner and/or insurance companies involved in the building construction project. 
     As indicated at Block G in  FIG. 34B , archiving all photographic and video records collected during Block E and uploading to the centralized web-based information server  111  at Block F for best practice and legal compliance purposes. 
     As indicated at Block H in  FIG. 34A , when all sections of the building under construction have been completely spray coated with CFIC liquid, and certified as such, the spray technicians remove the spray equipment from the building, and the builder proceeds to the next stages of construction and completes the building construction according to architectural and building specifications and plans. 
     By virtue of the Web-based system network  100  described above, it is now possible for professional fire-protection specialists to visually document the spraying of CFIC liquid over all exposed interior wood-surfaces of a mass timber building under construction so as to achieve Class-A fire-protection. After certifying with signatures, the proper on-site spray application of CFIC liquid, and Class-A fire-protection treatment of the mass timber building, these professional fire-protection specialists can capture and upload digital photographs and AV-recordings of certificates and related stamps, markings and signatures to a centralized website (e.g. system network database  113 A). At such a centralize website hosted on by servers  111 ,  112  and  113 , such uploaded and archived digital spray-project documents can be reviewed and downloaded when needed by architects, insurance companies, their inspectors, building owners, governmental officials, fire marshals and others who have a stake or interest in the matter of building fire-protection compliance and authentication. This remotely accessible facility, supported by the system network  100  provides a valuable and useful service to property/building owners, insurance underwriters, financial institutions (e.g. banks), and others who have great stakes in ensuring that particular mass timber buildings have been properly Class-A fire-protected using the spray-treatment methods of the present invention described in great detail hereinabove. 
     Specification of an Exemplary Embodiment of the System Network of the Present Invention Used During the Management of the Logistical Operations and Certifications Made and Documented During Class-A Fire-Protection Spray Treatment of Mass Timber Buildings During the Construction Phase 
     The system network  100  of the present invention has been described in great detail above in connection with ways in which to verify and document the CFIC liquid spray treatment of mass timber buildings on job sites during the construction phase, so that the various stakeholders will have remote access to a secure database  113 A containing photographic and audio-visual recording documentation, relating to certifications, verifications and documentation of each CFIC liquid spray project managed using the system network  100  of the present invention. However, when practicing the present invention, it is understood there will be many different ways to implement the useful concepts embraced by such inventions, when deploying and using a system network  100  to manage such operations across any enterprise of local, national or global scope. To help teach those with ordinary skill in the art to practice the present invention, an illustrative embodiment will be described at this juncture with reference to  FIGS. 32 through 37 . 
       FIG. 35A  shows architectural floor plans for a mass timber building scheduled to be sprayed with CFIC liquid to provide exposed interior surfaces with Class-A fire-protection. These floor plans will be uploaded and stored in the network database  113 A in the document folder/directory of the project.  FIG. 35B  shows architectural floor plans for an exemplary mass timber building, with a section marked up by the builder (indicated in dark thick lines), and scheduled to be sprayed with CFIC liquid to provide Class-A fire-protection.  FIG. 35C  shows marked-up architectural floor plans indicating a completed section that has been sprayed with CFIC liquid to provide exposed interior surfaces with Class-A fire-protection. All such marked-up floor plans will also be stored in the network database  113 A as part of the project&#39;s document package, as will be explained in greater detail herein below. 
     On the exemplary system network  100 , the following stakeholders can use the mobile application  120  (or web-browser equivalent) during a spray project on a building construction site, for the indicated purposes:
         Project Coordinator—To initiate the project and track progress of the projects   CFIC Supply Chain Manager—To start the chain of custody for the supply of CFIC materials in shipping CFIC totes (i.e. CFIC liquid concentrate in totes for diluting with water at job sites, or CFIC dry power in totes for mixing with water at job sites)   Site Spray Manager—To continue the chain of custody and electronically notify the site spray technician where they need to spray and then review to see if it has been sprayed   Site Spray Technicians—To continue the chain of custody and indicate sprayed areas   Spray Administrator Management—To review progress of the projects   Building Owners (i.e. Customers or site superintendent)—To continue the chain of custody and to order the spray contractor to spray parts or sections of their buildings   Insurance companies—To review real time progress on when their insured buildings are protected.   Fire fighters—To check if a building fire, to which they are responding, has been defended from fire using CFIC liquid spray treatment disclosed and taught herein.       

     The system network  100  and its distribution of mobile computing devices  117  (running mobile application  120  or web-browser equivalents) will have the capability to list all spray projects linked to the user, wherein each project contains numerous project details and information of different relevance to different stakeholders. In the illustrative embodiment, all projects will be searchable by customer name then project name. The building owners (often referred to as the “customer” with respect to the spray contractor) will only be able to access their projects, not the projects of others which will be maintained confidential on the system network  100 . The mobile application  120  will be able to send push-notifications where required, and users will choose what notifications they want to receive. For example, the customer&#39;s insurance company will have the option to only be notified when a portion of the building has been sprayed, or when only an entire floor has been sprayed. 
     Upon creating a new project on the system network  100 , the spray project coordinator will use the mobile application  120  to add various information items regarding the project, in the network database  113 A, including, for example: Customer Name (e.g. Building Owner Name); Project Name; Site Address; Superintendent&#39;s name and title, mobile number, email address; number of buildings associated with the project. 
     The mobile application  120  will then start with building  1  or building A, and prompt the user for the following information: Identify Building Type—by choosing a type from a drop down menu (i.e. apartment, townhouse, house, etc). If the Building Type is an apartment, then the user will be asked to describe the building (i.e.  3 ,  4  or  5  stories, square footage, total number of suites). 
     Mobile application  120  has the capability to import one or more pdf documents of each floor plan of the building into the project folder on the network database  113 A, as shown in  FIG. 28A . At this stage, the mobile application  120  will ask the user to import one or more pdf document(s) of the floor plan of each floor in the building, and will ask to identify the building, floor, and provide other information for subsequent use and marking. In particular, the application servers  112  will support advanced pdf document processing software enabling the users to index imported building floor plans to indicate the precise location where barcoded/RFID-tagged inspection checkpoints  300  (with integrated certificates of spraying, certificates of inspection) shown be posted during the project, as shown in  FIG. 30  for purposes of illustration. 
     The mobile application  120  will also request from the spray project coordinator, a Project Start Date when spray technicians should be begin spraying, in coordination with the construction schedule. Once the project has been created, the mobile application  120  will automatically send a push notification to: CFIC supply manager; building site coordinator; and spray administrators. Each user will be invited to project, with certain rights and privileges as determined and set by the spray project administrator (i.e. fire-protection provider administrator). 
     When the CFIC totes are ready to be filled or shipped, the mobile application  120  will prompt the CFIC Supply Manager user for various items of information relating to CFIC material required on certain building sites, in connection with specific projects. The user will navigate to the project on the mobile application  120 , and will store the CFIC tote information that multiple CFIC totes are required per project. For purposes of the present invention, the term “tote” shall mean any device fashioned to contain and hold a predetermined quantity of CFIC material, whether in dry power form, or concentrated liquid form, and may include bags, containers, bottles, or any other type of vessel capable of perform functions of containment and carrying. Estimates of CFIC material, based on the size of the building spray job, can be calculated using tables and other knowledge possessed by the CFIC supply chain manager, and may be automated using AI-based processes. In an illustrative embodiment, the user will select one of the following buttons; Add a CFIC Tote; Ship A CFIC Tote. If the user selects “add a CFIC tote” then they will be prompted for the following; the date (chosen from a calendar), the CFIC tote number, the size of the CFIC tote, dye (yes or no) mold protection (yes or no). If the user wants to “ship a CFIC tote”, then the user navigates to the project and selects the “ship a CFIC tote” button and chooses the CFIC tote the user wants to ship from a drop-down menu. The user will then pick a date from a calendar. The user will have to enter the ship date and the arrival date and name of the shipping carrier. 
     Once the CFIC Tote arrives at building job-site, the building site supervisor will log into the system network via the mobile application  120 , and perform the following system network operations. The building site supervisor (i.e. customer) will navigate to the project on the mobile application  120 , and sign off that the CFIC tote has arrived at the job site, with its locks intact and that CFIC tote has not been tampered. The site supervisor will use his/her finger to sign this confirmation in the mobile application  120 . 
     When the building owner (i.e. customer) wants to request a completed portion or section of a mass timber building to be sprayed-treated with CFIC liquid, the Building site supervisor will perform the following system network operations. The building site supervisor use the mobile application  120  to navigate to their project and enter the portion of their building they want sprayed with CFIC liquid. The building site supervisor will indicate the date the request was made, building number, the floor and the suites they want sprayed and date they want it sprayed. The mobile application  120  will send a notification via the mobile application  120  to the project coordinator, to let them know the request has been made. The spray project coordinator will use the mobile application  120  to either accept the requested spray date, or propose a new spray date to the building site supervisor. If the spray project coordinator (i.e. fire protection provider) accepts the proposed spray date, then a confirmation will be sent to the building site superintendent via the system network using the mobile application  120 . 
     Once the spray contractors (i.e. fire protection providers) arrive on-site of the building and are ready to spray CFIC liquid as requested, the site spray technician will perform the following operations in the system network  100  using the mobile application  120 . The site spray technician will mix a CFIC tote (e.g. by adding water to a tote contain CFIC liquid concentrate, or by adding water to the tote containing AAF31 powder and dye, if the project requires dye). If the project requires mold protection, then that will be added at the time the CFIC tote is mixed on site), and the spray technicians will sign in to the mobile application  120 , navigate to the project page, and click on “on-site CFIC tote preparation”. The spray technicians will choose the CFIC tote number from the drop-down list (previously created by the CFIC supply manager) and then enter the date, by clicking on a calendar date. The spray technicians will indicate if they have added dye, and or mold protection to the CFIC material. 
     When the spray date arrives, the building site superintendent will do a walk through of the intended spray area (i.e. floor plan) and inspect to make sure the area is ready to spray all exposed interior wood surfaces with CFIC liquid. The building site superintendent will attach an RFID tag and/or bar code symbol at each inspection checkpoint  300  marked on the floor plans of the mass timber building to be spray-treated with CFIC liquid spray, indicated by X marks in  FIG. 35B , and labeled with reference number  300 . The RFID tag and/or bar code symbol applied to the flexible substrate of each inspection checkpoint  300  will be encoded with a unique code identifier that is marked on the floor plan shown in  FIG. 35B , and uniquely associated with the project, and added to the network database  113 A on the system network  100 . 
     Preferably, the spray site superintendent will mount a barcoded/RFID-encoded inspection checkpoint  300  (bearing a certificate of spraying by the spray technician and a certificate of inspection by the spray supervisor and optionally the building site supervisor, printed on a thin flexible plastic sheet, on which a barcode symbol/RFID-tag are mounted) to (i) the entry door header of each room in each unit including the entrance to the unit, as illustrated in  FIG. 36  and also (ii) a stud located at every 10′ on one side of the hallway. Expectedly, the location of each barcoded/RFID-tagged inspection checkpoint  300  in any given project will vary. However, placement of such inspection checkpoints  300  should be selected to ensure that inspection is sufficient granular in resolution to not overlook significant areas of a sprayed mass timber building section under inspection. 
     Each barcoded/RFID-tagged inspection checkpoint  300  will include a bar code symbol and RFID tag  182  that has a unique project/inspection-checkpoint identifier (e.g. an alphanumeric character string) encoded into the symbology used in the barcode symbol and RFID tag identifier, and this project/inspection-checkpoint identifier will be used to identify subfolders or subdirectories where collection data, information and documents are stored in the project folder on the network database  113 A, maintained on the system network  100 . The project/inspection-checkpoint identifier will be read during each scan/read of the barcoded/RFID-tag inspection checkpoint  300 , and used by the mobile application to access the appropriate inspection checkpoint folder in the project folder where all such certifications of spraying, inspection and oversight, and photos, and videos are stored and archived for posterity. 
     At the beginning of each spray session, the spray technician will log into the system network  100  using the mobile application  120 , then navigate to the project page, select his name from a drop down or scrolling list, and indicate when he started spraying by clicking on a date and hour, minutes, seconds. The spray technician may also need to scan his barcoded ID card using the mobile application  120  for proper authentication and/or authorization purposes. He may also choose to record the presence of other members of his spray crew using the mobile application and their barcoded user ID cards and network ID numbers. The spray technician will then proceed to spray each assigned section of the building, and after spraying each mass timber building section, the spray technician will approach the barcoded/RFID-tagged inspection checkpoint  300  in the spray area, and read, sign and date the certification of spraying on the checkpoint substrate, mounted on the header surface illustrated in  FIG. 36 . The spray technician should diligently read, sign and date each and every certificate of spraying at the inspection checkpoint  300 , and treated as a condition of professionalism, duty, and employment, given the responsibility being entrusted to the individual with such operations. 
     At the end of the day, the spray technician will log into the system network  100 , if already logged out, using the mobile application  120 , and indicate the time when he finished spraying and indicate which suites on the floor plan pdf were sprayed with CFIC liquid. This will be done by drawing on his mobile computing device  117  (e.g. Apple iPad or Apple iPhone), by shading the PDF of the floor plan, over the appropriate suites and hallways, as shown in  FIG. 35C , which were in fact sprayed with CFIC liquid during his work session that date. This is the same floor plan that was previously loaded on the mobile application  120  by the customer/building owner, as shown in  FIG. 35A , but with the spray technicians markings (e.g. shading) added to the floor plan to indicate sections which have been spray treated with CFIC liquid. 
     At the end of each day or during the course of the day, the spray site superintendent will review the CFIC liquid spraying work performed on the job site that date, to ensure that the spray work has been completed properly. 
     The spray supervisor will visit each checkpoint  300 , and read, sign and date the certificate of inspection at the inspection checkpoint  300  after performing a diligent inspection at and around the checkpoint where spraying occurred earlier that day. At each barcoded/RFID-tagged inspection checkpoint  300  on the plan, the spray site supervisor will also scan each and every barcoded/RFID-tag inspection checkpoint  300 , and confirm with the system network  100  that the spray work at each inspection checkpoint has been completed properly. This process will involve displaying GUI screens on the mobile application  120  and checking off all suites/units and hallways have been completed and sprayed with CFIC liquid, and uploading such information to the project folder on the network database  113 A on the system network  100 . The process can also include capturing digital photos and AV-recordings of the site in the vicinity of each barcoded/RFID-tagged inspection checkpoint, verifying and documenting the certifications at each inspection checkpoint signed by the spray-technician after CFIC liquid spraying, and then uploading these captured digital photos and AV recordings to the project under the inspection checkpoint ID #, within the network database  113 A maintained by the system network  100 . 
     Also, it is desired that the building site superintendent visits each inspection checkpoint  300  and reads, signs and dates the certificate of inspection/oversight on the job site on that date. The building site superintendent should also use the mobile application  120  to capture digital images and videos of this certificate and competed inspection checkpoint  300 , and surrounding areas treated with CFIC liquid by the spray technician. Images and video recordings of the spray technician and supervisor can be included at each and every barcoded/RFID-tagged inspection checkpoint  300  and uploaded to the project folder, under the barcoded/RFID-tagged inspect checkpoints  300  assigned to the project. 
     The above steps above will be repeated every time the spray crew arrives at the building site until the project is complete. 
     Each time a CFIC tote is mixed at the job site by the spray technician, he/she will spray six 1-foot long 2×4&#39;s test boards ( 301 A,  301 B) covering all sides (e.g.  3  sprayed test boards for spray administrator and 3 sprayed test boards for the customer). The sample test boards  301  will be marked with the tote number. Alternatively, CFIC liquid sprayed test boards  301  can be made at or near barcode/RFID-tagged inspection checkpoints  300  in the building, and marked with the barcode/RFID ID number, and date they were sprayed. The fact that these sample test boards  301  were created will be recorded using the mobile application  120  in either the CFIC tote supply record section of each project, or under a barcode symbol/RFID-tag ID section of the project. Digital images and videos of these sprayed test boards  301  can be captured and uploaded to project folder in the network database  113 A maintained on the system network  100 . 
     At the completion of the project, the spray site superintendent will check the box that the project is complete. The spray site superintendent will request the building project superintendent to sign that the project has been completed, and such documentation will be made part of the project files stored in the network database  113 A on the system network  100 . A physical certificate of completion document can be signed and dated and scanned into pdf format and stored in the project file in the network database  113 A, using the mobile application  120  deployed on the system network  100 . Once the project has been completed, the system network  100  will send a notification to the local fire department, the insurance underwriting company, the building owner (i.e. customer), and the spray project coordinator. The system network will automatically organize all documents, data and information collected during the course of the project, and compile for presentation to various parties including the building owner, and property insurance underwriters. 
     The site spray technician will then collect all the sprayed samples  301 A,  301 B stored in barcoded storage sleeves  302 A,  302 B and deliver the first set of test samples  301 A to the building site superintendent or the building&#39;s architect, while providing the second set of the sprayed test samples  301 B to the spray supervisor to transport and archive in storage, as part of the fire protection provider&#39;s legal and business records.

     Method of Qualifying a Mass Timber Building for Reduced Property Insurance Based on Verified and Documented Spray-Based Clean Fire Inhibiting Chemical (CFIC) Liquid Treatment of all Exposed Interior Wood Surfaces of the Mass Timber Building During the Construction Phase Thereof 
       FIG. 38  shows the high-level steps required to practice the method of qualifying a mass timber building for reduced property insurance based on verified and documented spray-based clean fire inhibiting chemical (CFIC) liquid treatment of all of the exposed interior surfaces of the mass timber building, after each completed section. 
     As indicated at Block A in  FIG. 38 , a clean fire inhibiting chemical (CFIC) liquid is sprayed all over all interior surfaces of each completed sections of a mass timber building to provide Class-A fire-protection, as described above in  FIGS. 25A and 25B , using the GPS-tracked mobile clean fire-inhibiting chemical (CFIC) liquid spraying system  101 , as shown in  FIGS. 22A, 22B, 23A and 23B . 
     As indicated at Block B in  FIG. 38 , the spray-based Class-A fire-protection treatment process is verified and documented by capturing (i) GPS-coordinates and time/date stamping data generated by the GPS-tracked CFIC liquid spraying system  101  deployed on the system network  100 , and (ii) digital images and audio-video (AV) recordings of certificates of completion/inspection  181  stamped on completed sections after spray treatment, as illustrated in  FIGS. 24A and 24B , using the mobile application  120  on mobile computing device  117 . 
     As indicated at Block C in  FIG. 38 , the collected on-site spray treatment verification data is wirelessly transmitted to a central network database  113 A on the system network  100  to update its network database  113 A. 
     As indicated at Block E in  FIG. 38 , a company underwriting property insurance for the mass timber building accesses the central network database  113 A on the system network  100 , to verify the database records maintained for each mass timber building that has undergone spray-based Class-A fire protection treatment, to qualify the building owner for lower property insurance premiums, based on the verified Class-A fire-protection status of the sprayed-treated mass timber building. 
     As indicated at Block E in  FIG. 38 , upon the outbreak of a fire in the insured mass timber building/property, the local fire departments instantly and remotely assess the central network database  113 A using a mobile application  120  installed on mobile computing device  117 , so as to quickly determine Class-A fire-protected status of the mass timber building by virtue of CFIC liquid spray treatment of the mass timber building during the construction phase, and inform fireman tasked with fighting the fire that the mass timber building has been treated with Class-A fire-protection defense against fire.

     Specification of System Architecture of an Exemplary Mobile Smartphone System Deployed on the System Network of the Present Invention 
       FIG. 42A  shows an exemplary mobile the mobile client computing system (e.g. client device)  137  that is deployed on the system network  135  and supporting the many services offered by system network servers of the present invention. As shown in  FIG. 42B , the mobile computing device  137  ( 137 ′) can include a memory interface  202 , one or more data processors, image processors and/or central processing units  204 , and a peripherals interface  206 . The memory interface  202 , the one or more processors  204  and/or the peripherals interface  206  can be separate components or can be integrated in one or more integrated circuits. The various components in the mobile device can be coupled by one or more communication buses or signal lines. Sensors, devices, and subsystems can be coupled to the peripherals interface  206  to facilitate multiple functionalities. For example, a motion sensor  210 , a light sensor  212 , and a proximity sensor  214  can be coupled to the peripherals interface  206  to facilitate the orientation, lighting, and proximity functions. Other sensors  216  can also be connected to the peripherals interface  206 , such as a positioning system (e.g. GPS receiver), a temperature sensor, a biometric sensor, a gyroscope, or other sensing device, to facilitate related functionalities. A camera subsystem  220  and an optical sensor  222 , e.g. a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, can be utilized to facilitate camera functions, such as recording photographs and video clips. Communication functions can be facilitated through one or more wireless communication subsystems  224 , which can include radio frequency receivers and transmitters and/or optical (e.g. infrared) receivers and transmitters. The specific design and implementation of the communication subsystem  224  can depend on the communication network(s) over which the mobile device is intended to operate. For example, the mobile device  137  may include communication subsystems  224  designed to operate over a GSM network, a GPRS network, an EDGE network, a Wi-Fi or WiMax network, and a Bluetooth™ network. In particular, the wireless communication subsystems  224  may include hosting protocols such that the device  137  may be configured as a base station for other wireless devices. An audio subsystem  226  can be coupled to a speaker  228  and a microphone  230  to facilitate voice-enabled functions, such as voice recognition, voice replication, digital recording, and telephony functions. The I/O subsystem  240  can include a touch screen controller  242  and/or other input controller(s)  244 . The touch-screen controller  242  can be coupled to a touch screen  246 . The touch screen  246  and touch screen controller  242  can, for example, detect contact and movement or break thereof using any of a plurality of touch sensitivity technologies, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with the touch screen  246 . The other input controller(s)  244  can be coupled to other input/control devices  248 , such as one or more buttons, rocker switches, thumb-wheel, infrared port, USB port, and/or a pointer device such as a stylus. The one or more buttons (not shown) can include an up/down button for volume control of the speaker  228  and/or the microphone  230 . Such buttons and controls can be implemented as a hardware objects, or touch-screen graphical interface objects, touched and controlled by the system user. Additional features of mobile smartphone device  137  can be found in U.S. Pat. No. 8,631,358 incorporated herein by reference in its entirety. 
     Different Ways of Implementing the Mobile Client Machines and Devices on the System Network of the Present Invention 
     In one illustrative embodiment, the enterprise-level system network  135  is realized as a robust suite of hosted services delivered to Web-based client subsystems  137  using an application service provider (ASP) model. In this embodiment, the Web-enabled mobile application  153  can be realized using a web-browser application running on the operating system (OS) (e.g. Linux, Application IOS, etc) of a mobile computing device  137  to support online modes of system operation, only. However, it is understood that some or all of the services provided by the system network  135  can be accessed using Java clients, or a native client application, running on the operating system of a client computing device, to support both online and limited off-line modes of system operation. In such embodiments, the native mobile application  153  would have access to local memory (e.g. a local RDBMS) on the client device  137 , accessible during off-line modes of operation to enable consumers to use certain or many of the system functions supported by the system network during off-line/off-network modes of operation. It is also possible to store in the local RDBMS of the mobile computing device  137  most if not all relevant data collected by the mobile application for any particular fire-protection spray project, and to automatically synchronize the dataset for user&#39;s projects against the master datasets maintained in the system network database  148 A, within the data center  145  shown in  FIG. 41 . This way, when using an native application, during off-line modes of operation, the user will be able to access and review relevant information regarding any building spray project, and make necessary decisions, even while off-line (i.e. not having access to the system network). 
     As shown and described herein, the system network  135  has been designed for several different kinds of user roles including, for example, but not limited to: (i) building purchasers, builders, and architects who might or will have the authority to place or make purchase orders online to commence a Class-A fire-protected mass timber building project; and (ii) prefabrication building project administrators and technicians registered on the system network. Depending on which role, for which the user requests registration, the system network will request different sets of registration information, including name of user, address, contact information, information about mass timber buildings, builders, architects, etc. In the case of a web-based responsive application on the mobile computing device  137 , once a user has successfully registered with the system network, the system network will automatically serve a native client GUI, or an HTML5 GUI, adapted for the registered user. Thereafter, when the user logs into the system network, using his/her account name and password, the system network will automatically generate and serve GUI screens described below for the role that the user has been registered with the system network. 
     In the illustrative embodiment, the client-side of the system network  135  can be realized as mobile web-browser application, or as a native application, each having a “responsive-design” and adapted to run on any client computing device (e.g. iPhone, iPad, Android or other Web-enabled computing device)  137  and designed for use by anyone interested in managing, overseeing and/or monitoring on-site CFIC liquid spray projects involving owners of specific mass timber buildings seeking Class-A fire-protection. 
     Specification of Database Schema for System Network Database Supported on the System Network of the Present Invention 
     As shown in  FIG. 43 , the schema  154  includes objects such as, for example: users of the system (e.g. property owners, builders, insurance companies, etc); real property on which the building will be constructed (if known at the time of ordering); orders for custom or pre-specified prefabricated mass timber building; and construction project. Each of these objects have further attributes specified by other sub-objects indicated in  FIG. 43 , including, for example: project ID; raw lumber; CFIC liquid; CFIC liquid dip coating systems; Class-A fire-protected wood-framed components; and ISO-shipping containers.

     In one illustrative embodiment, the mobile application  153  and/or digital camera systems can be used to review digital images and audio-video (AV) recordings taken of CFIC liquid dipped-coated wood pieces along the production line, relating to prefabricated mass timber building components being fabricated, and uploaded to the system network database  148 A under the project ID # of the prefabricated building project. All captured documents and evidence of CFIC liquid dip-coated wood can be uploaded, logged and time/date-stamped and stored into the project-specific document folder maintained on the system network database  148 A of the system network  135  using document capture, time/date-stamping and cataloguing capabilities. 
     Alternatively, Class-A fire-protected lumber, and/or engineered wood products (EWPs), that are dip-coated in CFIC liquid, will be used to construct prefabricated Class-A fire-protected mass timber building components (e.g. wall panels, floor panels, roof panels, and stair assemblies). Once constructed in the factory on the production line, a barcoded/RFID-tagged inspection label  400  is applied to each and every prefabricated Class-A fire-protected mass timber building component produced on the production line  131 . Each barcoded/RFID-tagged inspection label  400  will include a bar code symbol and RFID tag that has a unique building-component identifier (e.g. an alphanumeric character string) encoded into the symbology used in the barcode symbol and RFID tag identifier, and this building-component identifier will be used to identify subfolders or subdirectories where collection data, information and documents are stored in a building-component subfolder (indexed with the building-component identifier), in the building-project folder on the network database  113 A, maintained on the system network  100 . The building-component identifier will be read during each scan/read of the barcoded/RFID-tag label  400 , and used by the mobile application  153  to access the appropriate building-component subfolder in the building project folder where all such certifications of dip-coating, inspection and oversight, and photos, and videos are stored and archived for posterity. 
     The mobile application  153  has access to all services supported in the mobile computing device  137  (e.g. Apple iPhone or iPad) as the case may be, for verifying and documenting the CFIC liquid spray treatment of each and every completed Class-A fire-protected mass timber building fabricated in the factory. Such documentation should include capturing and uploading digital images and AV-recordings of certificates of CFIC liquid dip-coating stamped and verified along the production line involved the fabrication process.

       FIG. 46  describes the primary steps involved in carrying out the method of operating a just-in-time prefabricated mass timber building factory system  130 , supporting multiple production lines  131 , as illustrated in  FIGS. 39A and 39B , for producing prefabricated Class-A fire-protected mass timber building components, as needed to construct pre-fabricated Class-A fire-protected mass timber buildings ordered online using the mobile application  153  described herein. 
     As indicated at Block A in  FIG. 46 , in response to a purchase order (PO) received at the factory system  130  for a customized or specified mass timber building, the factory system automatically generates a prefabricated mass timber building project for the order placed by a customer using the mobile application  153  installed and running on mobile computing system  137 A,  137 B, or through an equivalent website. 
     As indicated at Block B in  FIG. 46 , the factory system  130  analyzes the customized or specified mass timber building into its wood-framed components, and creates bill of materials (BOM) for the wood-building project. 
     As indicated at Block C in  FIG. 46 , the system  130  determines the type and quantity of raw wood and/or engineered wood product (EWP)  141  required to make each wood-framed component required by the mass timber building project. 
     As indicated at Block D in  FIG. 46 , the system  130  determines the supply clean fire inhibiting chemical (CFIC) liquid  142  required to dip-coat and treat wood and/or engineered wood product (EWP) for each wood-framed component required by the mass timber building. 
     As indicated at Block E in  FIG. 46 , the system  130  automatically dip-coats the wood and/or the EWPs in a high-speed dipping tank installed along a production line, as shown in the  FIG. 10A , each containing a controlled supply of CFIC liquid for dip-coating wood pieces at atmospheric pressure, to produce Class-A fire-protected wood required to fabricate Class-A fire-protected wood-framed components for the mass timber building, specified by the placed purchase order. 
     As indicated at Block F in  FIG. 46 , the system produces the Class-A fire-protected wood-framed components required to construct the ordered mass timber building. 
     As indicated at Block G in  FIG. 46 , a barcoded/RFID-tagged inspection label (with a code symbol and/or RFID tag)  400  is applied to each produced Class-A fire-protected mass timber building component  132 A,  132 B,  132 C,  132 D,  132 E produced for the ordered mass timber building. 
     As indicated at Block H in  FIG. 46 , each symbol coded/RFID-tagged Class-A fire-protected wood-framed component  132 A,  132 B,  132 C,  132 D,  132 E is loaded into an ISO-shipping container  136  assigned to the mass timber building project. 
     As indicated at Block I in  FIG. 46 , the ISO-shipping container  136  is delivered to the location where the mass timber building is to be constructed. Thereafter, construction of the Class-A fire-protected prefabricated mass timber building begins at the construction site. 
     In the event the purchaser of the prefabricated mass timber building requested on-site application of Class-A fire-protection spray treatment, using CFIC liquid (i.e. Hartindo AF31), a professional fire-protection spray treatment (provider) team will use the system network  100  shown in  FIG. 28  to apply, certify, verify and document the Class-A fire protection liquid spray process as described in detail above, in synchronism with the prefabricated builder&#39;s schedule. As each predesignated section of the mass timber building is constructed by assembling pre-fabricated Class-A fire-protected mass timber building components (e.g. wall panels, floor and roof truss panels, stair components, etc.), the spray technicians will spray treat all exposed interior surface of the completed section of the mass timber building, and certify, verify and document the spray treatment using the mobile application  153  using mobile computing devices  137  and services supported by the system network  100 . Once completed, the prefabricated Class-A fire-protected mass timber building will be double-protected with Class-A fire-protection, providing the building owner with many benefits, including potentially lower property insurance premiums, in view of the fact that significant risk of total destruction by fire has been significantly reduced or otherwise minimized. 
     By virtue of the JIT factory system  130 , it is now possible to produce, as needed, a custom or pre-specified mass timber building made from Class-A fire-protected mass timber building components, thereby minimizing inventory and cost of manufacture, and improving the quality and precision of prefabricated Class-A fire-protected prefabricated mass timber buildings. 
     Method of Qualifying Mass Timber Building for Reduced Property Insurance Based on Verified and Documented Clean Fire Inhibiting Chemical (CFIC) Liquid Dip-Coating of Wood Pieces During Fabrication of Class-A Fire-Protected Mass Timber Building Components for Prefabricated Mass Timber Buildings 
       FIG. 47  shows the high-level steps required to practice the method of qualifying a mass timber building for reduced property insurance based on verified and documented dip-coating of all wood pieces in clean fire inhibiting chemical (CFIC) liquid prior to the fabrication of Class-A fire-protected wood building components for used in constructing prefabricated Class-A fire-protected mass timber buildings. 
     As indicated at Block A in  FIG. 47 , dip-coating all wood in a clean fire inhibiting chemical (CFIC) liquid during the fabrication of Class-A fire-protected mass timber building components for constructing an ordered prefabricated building within a prefabricated mass timber building factory  130 . 
     As indicated at Block B in  FIG. 47 , verifying and documenting the CFIC liquid dip-coating and Class-A fire protection treatment of all wood pieces used to construct mass timber building components for the prefabricated Class-A fire-protected mass timber building, by capturing time/date stamping data, and digital images and videos of certificates of CFIC liquid dip-coating within the factory  130 . 
     As indicated at Block C in  FIG. 47 , the factory-collected Class-A fire-protection treatment verification data is wirelessly transmitted to a central network database  148 A on the system network  135  to update the central network database  148 A. 
     As indicated at Block E in  FIG. 47 , a company underwriting property insurance for the mass timber building accesses the central network database  148 A on the system network  135 , to verify the database records maintained for each mass timber building that has undergone spray-based Class-A fire protection treatment, to qualify the building owner for lower property insurance premiums, based on the verified Class-A fire-protection status of the sprayed-treated mass timber building. 
     As indicated at Block E in  FIG. 47 , upon the outbreak of a fire in the insured mass timber building/property, the local fire departments instantly and remotely assess the central network database  148 A using a mobile application  153 , so as to quickly determine Class-A fire-protected status of the mass timber building by virtue of CFIC liquid spray treatment of the mass timber building during the construction phase, and inform fireman tasked with fighting the fire that the mass timber building has been treated with Class-A fire-protection defense against fire. 
     Specifying the Method of and System for Producing Class-A Fire-Protective Cross-Laminated Timber (CLT) Building Components with UV/Moisture/Termite-Protection According to the Principles of the Present Invention 
       FIG. 48  shows a section of a Class-A fire-protected three-ply (3-ply) cross laminated timber (CLT) panel  249  provided with an added layer of UV/moisture/termite protection provided over a Class-A fire-protection layer, produced using the automated Class-A fire-protected prefabricated mass timber panel factory system  230  of the present invention illustrated in  FIGS. 50 through 51C . Typically, Douglas Fir, Western Larch &amp; SPF Grade 2 are used to make CLT panels. Defects such as large knots and resin or bark pockets are removed from the timber used for the CLT production process, based on the strength and final visual quality. 
       FIG. 49  shows flame spread and smoke development characteristics of Spruce Pine Fir (SPF) and Douglas Fir (DF) Class-A fire-protected lumber after being spray-coated with clean fire inhibiting chemical (CFIC) liquid (e.g. Hartindo AF21 Anti-Fire Chemical) as generally shown and illustrated in  FIGS. 50 and 51C , and tested in accordance with ASTM E84 and UL 723 test standards. 
       FIG. 50  shows an automated prefabricated building factory system  230  for producing Class-A fire-protected wood and mass timber buildings including Class-A fire-protected cross-laminated timber (CLT) products, Class-A fire-protected mass timber panels, and Class-A fire-protected wood-framed panels  249 , and depicted in other embodiments as  132  ( 132 A- 132 E) as shown in  FIGS. 39A and 39B . 
     As illustrated in  FIGS. 50 through 53C , this factory system  230  employs a first spraying stage  239  for robotically spraying CFIC liquid over prefabricated mass timber building panels, and a second spraying stage  241  for robotically spray a UV-light/moisture/termite-protective liquid coating over the Class-A fire-protection applied using the first spraying stage  339 . 
     Preferably, both stages  239  and  241  support the use of color and hyperspectral machine vision systems  239 K and  241 K capable of detecting and programmed to detect the application of CFIC liquid applied onto wood surfaces during the CFIC liquid spraying stage  239  and UV/moisture/termite-protective liquid spray applied during the second spraying stage  241 , and adjusting the controls at each stage to ensure that complete and adequate liquid coverage is applied over 100% of the wood surfaces at the speeds of operation supported by the factory system. In the illustrative embodiment, the machine vision systems can be realized using the In-Sight VC200 machine vision system or Insight 7000 machine vision system, in combination with automated barcode data capture systems, and application software suitably configured, commercially available from Cognex Corporation, Natick Mass., USA. Cognex offers powerful vision tools and industrial identification products for reliable performance and easy deployment into the automation equipment and factory environments taught in the present Patent Specification. Application software can be properly programmed and deployed to support automatic inspection of (i) CFIC liquid robotically sprayed over the wood surfaces of each prefabricated mass timber (and wood-framed) building panel is achieved during production, and (ii) automatic inspection of UV/moisture/termite-protective liquid robotically sprayed over the CFIC liquid coated wood surfaces of each prefabricated mass timber (and wood-framed) building panel. Without tedious software development, the software algorithm will train itself on a set of known good samples (e.g. CFIC liquid coated panels, and UV/moisture/termite-protective liquid coated panels) so as to create its reference models. The inspection process and algorithms will use such reference models to automatically identify and report defective spray patterns, as well as acceptable ones that have passed rigorous test standards. 
     As shown in  FIG. 50 , the automated factory system  230  comprises a number of automated stages integrated together under an automation and control subsystem  250 , namely: conveyor-chain transport mechanism  232  having various stages along the production line within the automated factory system; a controlled-drying stage  233  receiving short pieces of structural timber or lumber  231  from a supply warehouse maintained in or around the factory and drying them in a controlled manner well known in the art; a finger-jointing stage  234  for processing short-length pieces of dried timber (i.e. lumber) and automatically fabricating extended-length finger-jointed pieces of timber, as output from this stage; a lamination planing stage  235  for planing finger-jointed pieces of timber (i.e. laminations) to produce finger-jointed timber laminations  236 ; a cross-stacking and adhesive stage  236  for stacking timber laminations and applying an adhesive coating to the finger-jointed timer laminations; a pressing and curing stage  237  where the stacked and glued finger-jointed laminations are stacked in a cross-directional manner, provided with adhesive coating, and then placed in a pressing machine where the adhesive is cured under pressure to produce a cross-laminated timber (CLT) panel, beam or other product; CNC-driven trimming and fabrication stage  238  for trimming the cross-laminated timber (CLT) panels into CLT products, and fabricating the CLT panels to include apertures, and other interfaces and grooves formed therein, using CNC fabrication machinery; a tagging stage  238 A for applying a barcoded/RFID-tagged inspection checkpoint  400  affixed to each prefabricated CLT panel  249  being produced on the production line, and registering and documenting all subsequent fire-protection, UV-light, moisture and termite protection operations applied to the prefabricated panel being produced along the production line within the automated factory system  230 , including capturing video recordings of fabrication operations (e.g. certificates of spraying, inspection documents including video and other data captured by the production line machine vision systems  239 K,  241 K, and related verifications), within a network database  148 A maintained on the network; an automated wood moisture content measuring stage  238 B using preferably a non-contact type electronic moisture measuring instrument (e.g. PCE-PMI 1 Moisture Meter Instrument from PCE Americas, Inc., Jupiter, Florida) to electrically measure the moisture content of the prefabricated wood panel with a depth of penetration of about 20-40 mm, at certain predetermined locations around the mass timber panel, and automatically recording these moisture measurements (expressed in % water content) in the network database  148 A maintained on the network, and indexed to the barcoded panel identifier, and determine that the measured moisture content is less than 19% (or other predetermined threshold) before authorizing the prefabricated mass timber panel to the next stage for spraying with CFIC liquid for Class-A fire-protection, and rejecting the mass timber panel for spraying if the measured moisture content exceeds 19% (or other predetermined threshold); CFIC liquid spraying stage  239  supporting the robotic spraying of CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor) during Class-A fire-protection spraying operations on prefabricated panels  249 , to form a CFIC coating on the surfaces of the prefabricated mass timber building panel along the production line; a laminar air flow knife blower and drying tunnel stage  240 , for controllably drying the Class-A fire protected prefabricated wood building panel with CFIC liquid; a spray tunnel  241  for spraying a clean fire inhibiting chemical (CFIC) liquid (with e.g. Hartindo AF21 or AF31), with polymer, mold/biocide and termite/DOT agents over the surfaces of the worked CLT panel  249  to produce a coated CLT panel; a laminar air flow knife blower and drying tunnel stage  242  for quickly air drying the UV/moisture/termite-protected Class-A fire-protected CLT panel  249 ; and a labeling and packaging stage  243  for packaging and wrapping the final CLT product and preparing for shipping to a destination location or storage location. 
     As illustrated in  FIG. 50 , the finger-jointing lumber processing stage  234  can be configured as generally disclosed in US Patent Application Publication Nos. US20070220825A1 and US20170138049A1, incorporated herein by reference. At this this finger jointing stage, boards are trimmed and finger jointed to obtain the desired lengths and quality of lumber. In general, this stage involves robotic wood-working machinery, automation and programmable controls, well known in the finger-jointing wood art, and transforms multiple smaller-pieces of kiln-dried lumber into an extended-length piece of finger-jointed lumber, which is then planed and dimensioned during the next planning/dimensioning stage of the production line. An example of commercial equipment that may be adapted for the finger-jointing processing stage  234  may be the CRP 2500, CRP 2750 or CRP 3000 Finger Jointing System from Conception R.P., Inc., Quebec, Canada http://www.conceptionrp.com/finger-jointing-systems. 
     As illustrated in  FIG. 50 , the laminating planing stage  235  includes wood lamination planing equipment, such industrial band or rotary saws designed to cut, plane and dimension finger-jointed lumber pieces (i.e. laminations)  236  produced from the finger-jointing stage  234 , into finger-jointed timber laminations of a specified dimension and thickness. The lamination planing stage  235  can be realized using a band or radial saw as may be required to produce finger-jointed laminations. 
     As illustrated in  FIG. 50 , the stacking and adhesive application stage  239  can be realized using automated adhesive applicators well known in the art to apply a predetermined controlled amount of adhesive to each finger-jointed timber lamination  36  during the automated finger-jointing process. Each layer is sprayed with adhesive and the entire “sandwich” of stacked layers is then pressed vertically and horizontally in a large hydraulic press  40 . Typically, adhesives are waterproof and made from fire-resistant polyurethane, and essentially free of solvents and formaldehyde. 
     As illustrated in  FIG. 50 , the pressing and curing stage  237  can be realized using an automated pressing and curing machine well known in the art to apply a predetermined controlled amount of pressure to the timber laminations after they have been cross-configured, stacked, and placed into the machine for pressing and subsequent curing operations. 
     As illustrated in  FIG. 50 , prefabricated CLT panels  238  are cut to size, milled to spec, and finished as required using a Honegger CNC Panel Fabricator, or CNC bridge fabricator WMP240 by Weinmann, from Homag Machinery. The Honegger CNC Panel Fabricator supports a 4-head/5-axis CNC Fabricator capable of milling nearly any design specification.

     As shown in  FIG. 50 , the automated factory system  330  employs (i) a first robotically-controlled CFIC liquid spray-coating stage  339  installed and deployed along an automated production line for application of CFIC liquid spray according to the principles of the present invention, and (ii) a second independent spraying stage  341  for spray applying a polymer-based UV light and moisture-protective coating containing a biocide (e.g. for exterminating termites) sprayed over the Class-A fire-protection layer that has been applied using the robotically-controlled CFIC liquid spray-coating stage  341 . This two-stage prefabricated mass timber treatment process of the present invention, supported within automated factory system  230 , enables the fire inhibiting chemistry of the first stage to work independently of the UV/moisture-protective and biocidial chemistry of the second stage, and thereby delivering the protective functions each is designed to provide to the prefabricated mass timber panels (i.e. prefabricated wood-framed building panels), without the occurrence of adverse chemical interactions effecting protective the required and desired performance.

Preferably, each robotic spraying system  239 A,  239 ′ and  239 B,  239 B′ is supported by a high-resolution/high-definition (HD) color system  239 K that is interfaced with the automation and control subsystem  239 E, for guiding spraying operations performed on prefabricated mass timber panels, and providing visual feedback during such automated CFIC liquid spraying operations, to achieve and maintain the highest standards in quality control. Using such color machine vision systems for collecting video data of the spraying operations, it is possible to provide additional guidance as required to achieve predetermined standards of quality control along the production line. Using such color machine vision systems for collecting video data of the spraying operations, it is possible to provide additional guidance as required to achieve predetermined standards of quality control along the production line. 
     In the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the Class-A fire-protected CLT panel  249  interferes with the free radicals (H+, OH, O−) produced during the combustion phase of a fire, and breaks the fire&#39;s free-radical chemical reactions and extinguishes its flame. This is a primary fire suppression mechanism implemented by the CFIC-coatings deposited on wood surfaces in accordance with the principles of invention, disclosed and taught herein.

       FIG. 50D  shows the automated drying tunnel stage  242  shown in  FIG. 50 , comprising the deployment of (i) a laminar airflow scraping/wiping blowing instrument  242 A, and (ii) a heat-generating air-flow drying tunnel system  242 B for achieving quick drying of wet prefabricated Class-A fire-protected mass timber panels just sprayed with UV/moisture/termite-protection liquid during the factory-applied Class-A fire-protection stage implemented along the production lines of the automated factory system shown in  FIG. 50 . As shown in  FIG. 50D , a system controller  240 A 2  is provided to generate and supply control signals to control the operation of the laminar air flow blower  240 A and air-flow drying tunnel  240 B mounted along the conveyor of the production line. During factory operation, the system controller  242 A controls the air knife blower  242 A and drying tunnel  242 B as prefabricated wood building panels are transported along the conveyor system on the production line of the factory. 
     In the illustrative embodiment shown in  FIG. 50 , a blended liquid solution of fire-protection, moisture-protection, UV-protection, mold/termite-protection (e.g. biocidial agent) is mixed as a liquid solution that is stored in a reservoir and supplied to the spraying tunnel stage  241  for application over prefabricated Class-A fire-protected mass timber (or wood-framed) panels. As shown in  FIGS. 50C ,  50 C 1 ,  50 C 2  and  50 D, the spray tunnel stage  241  comprises: a storage reservoir  241 A 10  for storing a large supply of moisture/fire/UV-protective liquid chemical for treating the wood material of the prefabricated panel  249 ; a spray tunnel  241 A,  241 A′,  241 B,  241 B′ for supporting an array of spray nozzles arranged about the conveyor rails  242 C, operably connected to a liquid pump connected to the storage tank under the controller  250 , to provide a 360 degrees of spray coverage in the tunnel for spray-coating Class-A fire-protected CLT within moisture/fire/UV-protection liquid sprayed to cover 100% of surfaces of such CLT panels as they are being transported through the spray tunnel  241 ; and a drying tunnel stage  242  installed after the spray tunnel stage  241  for quick air drying of spray-coated Class-A fire-protected CLT panels, as they move through the drying tunnel  242  towards the labeling and packaging stage  243  under the control of the controller  250 . 
     In the preferred embodiment, the blended moisture/fire/UV/mold/termite protection liquid  241 B 9  sprayed in the spray tunnel  241  is formulated as follows: 70% by volume Hartindo AF21 liquid (or Hartindo AF31); 10% by volume, polymer; 10% by volume, a biocide; and 10% by volume, termite agent, Disodium Octaborate Tetrahydrate (DOT). It is understood, however, that other formulations may be used with acceptable results. 
     As shown, the Class-A fire-protected CLT panels  249  are fed through the spray tunnel stage  242  for spray coating with a moisture/fire/UV-protective liquid coating over the entire surface as each spray-coated Class-A fire-protected CLT panel is fed through the spray tunnel  241  for a second stage of UV/moisture/termite-protection. Then, the Class-A fire-protected CLT panel is quick-dried while being passed through the drying tunnel  242  disposed immediately after the spraying tunnel  242 . This produces a Class-A fire-protective CLT product  249  with a moisture/fire/UV/mold/termite protective coating as it exits the production line, improving the durability of the Class-A fire-protective CLT product when exposed to outdoor weather conditions during and after the construction phase.

During the prefabrication process, intelligence and evidence of fire-protection, UV/moisture protection and termite protection are automatically collected on each prefabricated panel and linked to the barcoded/RFID-tagged checkpoint  400 , is stored in a central network database  148  maintained at the data center  145 . The method will be detailed below with reference to  FIGS. 50A through 50D . 
     As indicated at Block A in  FIG. 51A , a high-speed fire-protected lumber production line is installed and operated in the automated prefabricated mass timber panel factory system  230 . As shown in  FIG. 50A , the production line is provided with a reservoir tank  239 A 10  with a large supply of clean fire-inhibiting chemical (CFIC) liquid that is continuously supplied to the automated in-line CFIC liquid spray coating stage  239  of the mass timber factory  230  installed along the production line. 
     As indicated at Block B in  FIG. 51A , a supply of untreated short-length timber is loaded onto the conveyor-chain transport mechanism  232  installed along the production line. 
     As indicated at Block C in  FIG. 51A , the untreated short-length lumber is loaded into the controlled drying stage of the production line so to produce suitably dried short-length lumber for supply to the finger-jointing processing stage  234 . 
     As indicated at Block D in  FIG. 51A , controllably-dried short-length lumber is supplied into the finger-jointing processing stage  234 , for producing extended-length finger-jointed timber pieces. 
     As indicated at Block E in  FIG. 51B , pieces of extended length finger-jointed timber are planed into pieces of finger-jointed timber laminations, which are output onto the conveyor-chain transport mechanism. 
     As indicated at Block F in  FIG. 51B , adhesive material is applied to the Class-A fire-protected timber laminations produced during Block H, as they pass through the adhesive application stage. 
     As indicated at Block G in  FIG. 51B , at the pressing &amp; curing stage, n-layers of timber laminations are pressed together with applied adhesive between the laminations, and then the adhesively joined laminations are allowed to cure under pressure to produce n-ply mass timber (e.g. CLT, GLT) products. 
     As indicated at Block H in  FIG. 51B , apertures in CLT panels are trimmed and formed using CNC machines to produce prefabricated mass timber panels. 
     As indicated at Block I in  FIG. 51B , clean fire inhibiting chemical (CFIC) liquid is sprayed over all the exterior surfaces of the prefabricated mass timber panel to produce a Class-A fire-protected mass timber panel. 
     As indicated at Block J in  FIG. 51C , the Class-A fire protected mass timber panel is passed through a drying tunnel  240  with a laminar air flow knife blowing device  240 A and/or heating elements  240 B to accelerate air-drying of the CFIC liquid sprayed all over the prefabricated mass timber panel. 
     As indicated at Block K in  FIG. 51C , the Class-A fire-protected mass timber panel is fed through a spray coating tunnel  241  and a liquid biocidial polymer with UV and moisture protection are deposited in the form of a coating sprayed all over the Class-A fire-protected mass timber panel  249 . 
     As indicated at Block L in  FIG. 51C , the protective-coated Class-A fire-protected mass timber panel is transported through a drying tunnel  242  to rapidly air dry the UV light, moisture and termite protected Class-A fire-protected mass timber panel as it is passed through the drying tunnel  242 . 
     As indicated at Block M in  FIG. 51C , the UV/moisture/termite-protected Class-A fire-protected mass timber panel  249  is labeled, packaged and prepared for shipping to a destination. The barcoded/RFID-tagged inspection checkpoint  400  remains affixed to the prefabricated panel  249  providing immediate access to all documentation, certifications and verifications relating to the fire, UV, moisture and termite protection provided to the building construction panel (e.g. certificates of spraying, inspection documents including video and other data captured by the production line machine vision systems  239 K,  241 K, and related verifications), and stored in the central database  148 A maintained on the network. Whenever fire insurance risk managers and fire risk engineers require information about the Class-A fire-protected mass timber panels  249  produced along the production lines of the factory system  330 , for whatever purpose at hand, all that is needed is to read the barcode/RFID-tag  400  on the panel to access the network database  148 A to access and review supporting documentation collected during fabrication. 
     Specifying a Second Method of and System for Producing Class-A Fire-Protective Cross-Laminated Timber (CLT) Building Components with UV/Moisture/Termite-Protection According to the Principles of the Present Invention 
       FIG. 52  shows a section of UV/moisture/termite-protected and Class-A fire-protected three-ply (3-ply) cross-laminated timber (CLT) panel  349  produced using the automated Class-A fire-protected prefabricated mass timber panel factory system  330  of the present invention. As illustrated in  FIGS. 54 through 55C , this factory system  330  employs a first curtain-coating stage  339  for CFIC liquid spray application, and a second spraying stage  341  for robotically spray a UV-light/moisture/termite-protective liquid coating over the Class-A fire-protection applied using the curtain-coating stage  339 . 
     Preferably, both stages  339  and  341  support the use of color and hyperspectral machine vision systems  339 K and  341 K capable of detecting and programmed to detect the application of CFIC liquid applied onto wood surfaces during the curtain-coating stage  339 , and the application of UV/moisture/termite-protective liquid spray applied onto CFIC liquid coated surfaces during the spraying stage  341 , and adjusting the controls at each stage to ensure that complete and adequate liquid coverage is applied over 100% of the wood surfaces at the speeds of operation supported by the factory system. In the illustrative embodiment, the machine vision systems can be realized using the In-Sight VC200 machine vision system or Insight 7000 machine vision system, in combination with automated barcode data capture systems, and application software suitably configured, commercially available from Cognex Corporation, Natick Mass., USA. Cognex offers powerful vision tools and industrial identification products for reliable performance and easy deployment into the automation equipment and factory environments taught in the present Patent Specification. Application software can be properly programmed and deployed to support automatic inspection of (i) CFIC liquid robotically sprayed over the wood surfaces of each prefabricated mass timber (and wood-framed) building panel is achieved during production, and (ii) automatic inspection of UV/moisture/termite-protective liquid robotically sprayed over the CFIC liquid coated wood surfaces of each prefabricated mass timber (and wood-framed) building panel. Without tedious software development, the software algorithm will train itself on a set of known good samples (e.g. CFIC liquid coated panels, and UV/moisture/termite-protective liquid coated panels) so as to create its reference models. The inspection process and algorithms will use such reference models to automatically identify and report defective spray patterns, as well as acceptable ones that have passed rigorous test standards. 
       FIG. 53  shows flame spread and smoke development characteristics of Spruce Pine Fir (SPF) and douglas Fir Class-A fire-protected lumber, after being spray-coated with clean fire inhibiting chemical (CFIC) liquid as generally shown and illustrated in  FIGS. 52 through 52C , and tested in accordance with ASTM E84 and UL 723 test standards. 
     As shown in  FIG. 54 , the automated factory system comprises a number of automated stages integrated together under automation and control, namely: conveyor-chain transport mechanism  332  having various stages; a controlled-drying stage  333  receiving short pieces of structural timber or lumber  331  from a supply warehouse maintained in or around the factory and drying them in a controlled manner well known in the art; a finger-jointing stage  334 , for processing short-length pieces of dried timber (i.e. lumber) and automatically fabricating extended-length finger-jointed pieces of timber, as output from this stage; a lamination planing stage  335  for planing finger-jointed pieces of timber (i.e. laminations) to produce finger-jointed timber laminations  336 ; a cross-stacking and adhesive stage  336  for stacking timber laminations and applying an adhesive coating to the finger-jointed timer laminations; a pressing and curing stage  337  where the stacked and glued finger-jointed laminations are stacked in a cross-directional manner, provided with adhesive coating, and then placed in a pressing machine where the adhesive is cured under pressure to produce a cross-laminated timber (CLT) panel, beam or other product; CNC trimming and fabrication stage  338  for trimming the cross-laminated timber (CLT) panels into CLT products, and fabricating the CLT panels to include apertures, and other interfaces and grooves formed therein using CNC fabrication machines; a tagging stage  338 A for applying a barcoded/RFID-tagged inspection checkpoint  400  affixed to each prefabricated CLT panel  349  being produced on the production line, and registering and documenting all subsequent fire-protection, UV-light, moisture and termite protection operations (i.e. liquid spraying operations) applied to the prefabricated panel  349  being produced along the production line within the automated factory system  330 , including capturing video recordings of fabrication operations (e.g. certificates of spraying, inspection documents including video and other data captured by the production line machine vision systems  339 K,  341 K, and related verifications), and storing these documents within a network database  148 A maintained on the network; an automated wood moisture content measuring stage  338 B using preferably a non-contact type electronic moisture measuring instrument (e.g. PCE-PMI 1 Moisture Meter Instrument from PCE Americas, Inc., Jupiter, Florida) to electrically measure the moisture content of the prefabricated wood panel with a depth of penetration of about 20-40 mm, at certain predetermined locations around the mass timber panel, and automatically recording these moisture measurements (expressed in % water content) in the network database  148 A maintained on the network, and indexed to the barcoded panel identifier, and determine that the measured moisture content is less than 19% (or other predetermined threshold) before authorizing the prefabricated mass timber panel to the next stage for spraying with CFIC liquid for Class-A fire-protection, and rejecting the mass timber panel for spraying if the measured moisture content exceeds 19% (or other predetermined threshold); a CFIC liquid spraying stage  339  supporting the robotic spraying of CFIC liquid (e.g. Hartindo AF21 Total Fire Inhibitor) during Class-A fire-protection spraying operations, to form a CFIC coating on the surfaces of the prefabricated mass timber building panel along the production line; a laminar air flow blowing knife and drying tunnel stage  340 , for controllably drying the Class-A fire-protected prefabricated wood building panel with CFIC liquid; a liquid spraying tunnel stage  341  for spraying a clean fire inhibiting chemical (CFIC) liquid (with e.g. Hartindo AF21 or AF31), with liquid polymer, mold/biocide and termite/DOT agents, sprayed over the surfaces of the worked CLT panel  349  to produce a coated Class-A fire-protected CLT panel; a laminar air flow knife blowing and air drying tunnel stage  342  for quickly air drying the UV/moisture/termite-protected Class-A fire-protected CLT panel  349 ; and a labeling and packaging stage  343  for packaging and wrapping CLT product  349  and preparing for shipping to a destination location, or storage location. 
     As illustrated in  FIG. 54 , the finger-jointing lumber processing stage  334  can be configured as generally disclosed in US Patent Application Publication Nos. US20070220825A1 and US20170138049A1, incorporated herein by reference. At this this finger jointing stage, boards are trimmed and finger jointed to obtain the desired lengths and quality of lumber. 
     In general, this stage involves robotic wood-working machinery, automation and programmable controls, well known in the finger-jointing wood art, and transforms multiple smaller-pieces of kiln-dried lumber into an extended-length piece of finger-jointed lumber, which is then planed and dimensioned during the next planning/dimensioning stage of the production line. An example of commercial equipment that may be adapted for the finger-jointing processing stage  334  may be the CRP 2500, CRP 2750 or CRP 3000 Finger Jointing System from Conception R.P., Inc., Quebec, Canada http://www.conceptionrp.com/finger-jointing-systems. 
     As illustrated in  FIG. 54 , the laminating planing stage  335  includes wood lamination planing equipment, such industrial band or rotary saws designed to cut, plane and dimension finger-jointed lumber pieces (i.e. laminations)  336  produced from the finger-jointing stage  334 , into finger-jointed timber laminations of a specified dimension and thickness. The lamination planing stage  335  can be realized using a band or radial saw as may be required to produce finger-jointed laminations. 
     As illustrated in  FIG. 54 , the stacking and adhesive application stage  339  can be realized using automated adhesive applicators well known in the art to apply a predetermined controlled amount of adhesive to each finger-jointed timber lamination  331  during the automated finger-jointing process. Each layer is sprayed with adhesive and the entire “sandwich” of stacked layers is then pressed vertically and horizontally in a large hydraulic press. Typically, adhesives are waterproof, based on fire-resistant polyurethane, and are substantially free of solvents and formaldehyde. 
     As illustrated in  FIG. 54 , the pressing and curing stage  337  can be realized using an automated pressing and curing machine well known in the art to apply a predetermined controlled amount of pressure to the timber laminations after they have been cross-configured, stacked, and placed into the machine for pressing and subsequent curing operations. 
     As illustrated in  FIG. 54 , fabricated assembled CLT panels  338  are cut to size, milled to spec, and finished as required using a Honegger CNC Panel Fabricator, or CNC bridge fabricator WMP240 by Weinmann, from Homag Machinery. The Honegger CNC Panel Fabricator supports a 4-head/5-axis CNC Fabricator capable of milling nearly any design specification.

As shown in  FIG. 54D , a system controller  342 A 2  is provided to generate and supply control signals to control the operation of the laminar air flow blower  342 A, and air-flow (or radiant) drying tunnel  342 B mounted along the conveyor of the production line. 
     In the illustrative embodiment of the present invention, a blended liquid solution of fire-protection, moisture protection, UV light protection, and mold and termite protection agents (e.g. biocidial agents) is supplied to the spraying tunnel stage  341 , and serves as the “UV/moisture/termite-protection liquid” that is sprayed from the spray nozzles of the spraying stations deployed along the production lines of the automated factory of the present invention. As shown in  FIGS. 54C ,  54 C 1 ,  54 C 2  and  54 D, the liquid spraying tunnel stage  341  comprises: a storage tank for storing a large supply of UV/moisture/termite-protective liquid chemical  341 A 10 ; a liquid spraying tunnel  341  supporting an array of spray nozzles  341 A 7  supported by the robotic arm, and operably connected to a liquid pump connected to the storage tank  341 A 10  under the controller  350 , to provide 360 degrees of spray coverage for spray-coating Class-A fire-protected CLT panels with UV/moisture/fire/termite-protection liquid sprayed to cover 100% of surfaces of such CLT panels as they are being transported through the spray tunnel  341 ; and an air drying tunnel stage  342  installed after the spraying tunnel stage  341  for quick drying of spray-coated Class-A fire-protected CLT panel, as they move through the air drying tunnel  342  towards the labeling and packaging stage  343  under the control of the controller  350 . 
     In the preferred embodiment, the blended moisture/fire/UV/mold/termite-protection liquid  341 A 10  sprayed in the spray tunnel  341  is formulated as follows: 70% by volume Hartindo AF21 liquid (or Hartindo AF31); 10% by volume, polymer; 10% by volume, a biocide; and 10% by volume, termite agent, Disodium Octaborate Tetrahydrate (DOT). 
     As shown, the Class-A fire-protective CLT panels  349  are continuously feed through the spray tunnel stage  342  for spray coating a UV/moisture/fire-protective liquid coating over the entire surface as each spray-coated Class-A fire-protected CLT panel is fed through the spray tunnel  341  for a second stage of UV/moisture/termite-protection. Then, the Class-A fire-protected CLT panel  349  is quick-dried while being passed through the drying tunnel  342  disposed immediately after the spray tunnel  342 . This produces a Class-A fire-protective CLT product with a moisture/fire/UV/mold/termite protective coating as it exits the production line, improving the durability of the Class-A fire-protective CLT product when exposed to outdoor weather conditions during the construction phase. 
     In the presence of a flame, the chemical molecules in the CFIC-coating on the surface of the Class-A fire-protected CLT panel  349  interferes with the free radicals (H+, OH, O−) produced during the combustion phase of a fire, and breaks the fire&#39;s free-radical chemical reactions and extinguishes its flame. This is a primary fire suppression mechanism implemented by the CFIC-coatings deposited on wood surfaces in accordance with the principles of invention, disclosed and taught herein. 
       FIGS. 55A, 55B and 55C  describes the high level steps carried out when practicing the method of producing UV/moisture/termite-protected and Class-A fire-protected cross-laminated timber (CLT) products in the automated Class-A fire-treated CLT factory illustrated in  FIGS. 54, 54A ,  54 A 1 ,  54 A 2 ,  54 B,  54 C,  54 C 1 ,  54 C 2  and  54 D. During the prefabrication process, intelligence and evidence of fire-protection and UV/moisture/termite-protection are automatically collected on each prefabricated panel and linked to the barcoded/RFID-tagged checkpoint  400 , is stored in a central network database  148  maintained at the data center  145 . The method will be detailed below with reference to  FIGS. 54 through 55D . 
     As indicated at Block A in  FIG. 55A , a fire-protected lumber production line is installed in an automated prefabricated mass timber panel factory system  330 , and the production line is provided with a reservoir tank  339 D supplying a large supply of clean fire-inhibiting chemical (CFIC) liquid  3391  to the automated CFIC liquid curtain-coating stage  339  of the mass timber factory, shown in  FIG. 54A . 
     As indicated at Block B in  FIG. 55A , a supply of untreated short-length timber is loaded onto the conveyor-chain transport mechanism  339 A,  339 B installed along the production line. 
     As indicated at Block C in  FIG. 55A , the untreated short-length lumber is loaded into the controlled drying stage  333  of the production line so to produce suitably dried short-length lumber for supply to the finger-jointing processing stage  334 . 
     As indicated at Block D in  FIG. 55A , a controllably-dried short-length lumber is supplied into the finger-jointing processing stage  334 , producing extended-length finger-jointed timber pieces. 
     As indicated at Block E in  FIG. 55B , pieces of extended length finger-jointed timber are planed into pieces of finger-jointed timber laminations, and output onto the conveyor-chain transport mechanism  332 . 
     As indicated at Block F in  FIG. 55B , adhesive material is applied to the Class-A fire-protected timber laminations produced during Block H, as they pass through the adhesive application and stacking stage  336 . 
     As indicated at Block G in  FIG. 55B , at the pressing &amp; curing stage  337 , n-layers of timber laminations are pressed together with applied adhesive between the laminations, and then the adhesively joined laminations are cured to produce n-ply mass timber (CLT, GLT, NLT) products. 
     As indicated at Block H in  FIG. 55B , the mass timber panel is trimmed and apertures are formed to produce a prefabricated mass timber panel. 
     As indicated at Block I in  FIG. 55B , clean fire inhibiting chemical (CFIC) liquid is sprayed over all the exterior surfaces of the mass timber panel to produce class-a fire protected mass timber panel. 
     As indicated at Block J in  FIG. 55C , Class-A fire-protected mass timber panel is passed through a drying tunnel  340  preceded by a laminar air flow knife device  340 A, and followed by heating elements  340 B to accelerate drying of the CFIC liquid sprayed over the prefabricated mass timber panel. 
     As indicated at Block K in  FIG. 55C , Class-A fire-protected mass timber panels are fed through a spray coating tunnel  341  and a liquid biocide agent (for termites) mixed with UV light and moisture protection (e.g. liquid polymer) is deposited in the form of a liquid coating spray-applied over the Class-A fire-protected mass timber panel. 
     As indicated at Block L in  FIG. 55C , the UV/moisture/termite-protected Class-A fire-protected mass timber panel is transported through a drying tunnel  342  to rapidly air dry the UV-light, moisture and termite protective-coated Class-A fire-protected mass timber panel as it passes through the drying tunnel  342 . 
     As indicated at Block M in  FIG. 55C , the Class-A fire-protected mass timber panel with UV/moisture/termite-protection and a barcoded/RFID-tagged inspection checkpoint  400 , is labeled, packaged and prepared for shipping to a destination. The barcoded/RFID-tagged inspection checkpoint  400  remains affixed to the prefabricated mass timber panel  249  providing stakeholders with immediate access to all documentation, certifications and verifications relating to the fire, UV, moisture and termite protection provided to the prefabricated mass timber building construction panel (e.g. video/photographic recordings of certificates of spraying, inspection documents including video and other data captured by the production line machine vision systems  239 K,  241 K, and related verifications) and stored in the central database  148 A maintained on the network. Whenever fire insurance risk managers and fire risk engineers require information about the Class-A fire-protected mass timber panels  349  produced along the production lines of the factory system  330 , for whatever purpose at hand, all that is needed is to read the barcode/RFID-tag  400  on the panel to access the network database  148 A to access and review supporting documentation collected during fabrication. This new functionality represents a significant contribution to and advancement in the manufacturing of prefabricated mass timber (and wood-framed) building panels, and Class-A fire-protected prefabricated mass timber and wood-framed buildings to be constructed therefrom on construction sites remotely managed from a central location using advanced communication networks. 
     Modifications to the Present Invention which Readily Come to Mind 
     The illustrative embodiments disclose the use of clean fire inhibiting chemicals (CFIC) from Hartindo Chemicatama Industri, particular Hartindo AAF21 and AAF31 and Dectan chemical, for applying and forming CFIC-coatings to the surface of wood, lumber, and timber, and other engineering wood products. However, it is understood that alternative CFIC liquids will be known and available to those with ordinary skill in the art to practice the various methods of Class-A fire-protection according to the principles of the present invention. 
     These and other variations and modifications will come to mind in view of the present invention disclosure. 
     While the illustrative embodiments included primarily mass timber buildings and building components, it is understood that all such methods and apparatus of the present invention can be readily applied to prefabricated wood-framed buildings disclosed and taught in Applicant&#39;s other pending US patent applications including: Ser. No. 15/829,914 filed 2 Dec. 2017; Ser. No. 15/866,451 filed 9 Jan. 2018; Ser. No. 15/866,454 filed 9 Jan. 2018; Ser. No. 15/866,456 filed 9 Jan. 2018; Ser. No. 15/874,874 filed 18 Jan. 2018; Ser. No. 15/921,617 filed 14 Mar. 2018; and Ser. No. 15/952,183 filed 12 Apr. 2018; each said pending US patent application being incorporated herein by reference in its entirety as if fully set forth herein. 
     While the on-site applied spray of CFIC liquid was shown for newly constructed prefabricated Class-A fire-protected mass timber buildings, it is understood that this method of Class-A fire-protection treatment also can be practiced on older buildings having: (i) open unfinished attic spaces disposed above roof-trusses with open, unfinished ceiling surfaces, wall and floor surfaces, where bare interior wood surfaces are exposed and at high-risk to fire; and (ii) open unfinished basement spaces, where wall panels are open, exposed and at high-risk to fire. In such environments, the Class-A fire-protection spray-treatment method of the present invention can be practiced with excellent results. 
     While several methods have been disclosed for providing Class-A fire-protection to the spray-treated surfaces of mass timber building components, such as CLT, NLT and GLT, it is understood that the same methods can be practiced for the purpose of reducing charring of mass timber building components in a mass timber building. Such methods will involve applying to exteriorly exposed surfaces of mass timber building component, a clean fire inhibiting chemical (CFIC) liquid so as to form an added layer of CFIC providing Class-A fire-protection to the sprayed surface. Then, in the presence of a fire in the mass timber building, the layer(s) of the CFIC coating will interfere with the free radical chemical reactions in the combustion phase of the fire, thereby preventing significantly less charring of timber on the exterior surfaces of the sprayed mass timber building components. Spray-applied as well as brush-applied methods can be used to apply a coating of clean fire inhibiting chemical (CFIC) liquid to the exteriorly exposed surfaces of mass timber building component in accordance with the principles of the present invention. Such methods can offer great value is reducing damage to mass-timber buildings in the event of building fires because repairing char damage to mass timber building components is almost impossible in most instances without replacing fire-damaged mass-building components, which can be time-consuming, complex, and very expensive. 
     Also, it is understood that there will be a great need to apply the fire-protection spray methods of the present invention, disclosed in Applicant&#39;s pending U.S. patent application Ser. No. 15/866,451, and incorporated herein by reference in its entirety, to protect mass timber buildings from wild fires by automatically spraying water-based environmentally clean fire inhibiting chemical (CFIC) liquid over the exterior surfaces of the building, surrounding ground surfaces, shrubs, decking and the like, prior to wild fires reaching such buildings. 
     While several modifications to the illustrative embodiments have been described above, it is understood that various other modifications to the illustrative embodiment of the present invention will readily occur to persons with ordinary skill in the art. All such modifications and variations are deemed to be within the scope and spirit of the present invention as defined by the accompanying Claims to Invention.
