     BACKGROUND OF INVENTION 
     Field of Invention 
     The present invention relates to improvements in methods of and apparatus for collecting intelligence and various forms of information relating to the condition of wood-framed and mass timber buildings under construction, including early detection and response to fire outbreaks and arson attacks. 
     Brief Description of the State of Knowledge in the Art 
     Before arriving on the scene of fire inside a wood-framed or mass timber building under construction, fire fighters and early responders search quickly for early technical information that will help the Fire Chief decide on whether to incur serious risks in attempting to save a burning wood-framed building under construction. A seasoned Fire Chief will attempt to determine the behavior of the building fire and whether or not it is struggling to generate combustion gasses that collect in the floor ceiling assemblies of the building construction, to achieve flash over conditions when the entire building will become quickly engulfed in fire. 
     While a few vendors, such as Pillar Technologies, NYC, currently offer wireless sensors for installation in buildings under construction, these systems fail to collect the necessary intelligence that might help fire chiefs make the necessary decisions in response to a building fire, such as sending firefighters into a burning building under construction, or allowing it to burn and defending neighboring buildings. 
     In view of the above shortcomings and drawbacks, significant improvements are needed in the field of wood-frame and mass timber building construction, including information collection, analysis and response to fire outbreaks and arson attacks, while overcoming the shortcomings and drawbacks of prior art apparatus and methodologies.

     DETAILED DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS OF THE PRESENT INVENTION 
     Referring to the figures in the accompanying Drawings, the illustrative embodiments of the system and will be described in great detail, wherein like elements will be indicated using like reference numerals. 
     Overview on the Early Building Fire-Outbreak and Arson-Attack Detection and Elimination System of the Present Invention 
       FIG. 1  shows a wood-framed building under construction, in which the early building fire-outbreak/arson-attack detection and elimination system of the present invention shown in  FIGS. 3 through 25  is embodied. In general, this system  1  will include some basic high level components to construct a global infrastructure, within which to integrate various subsystems which will be described hereinafter. These basic high level components include: a global navigation satellite system (GHSS)  170  with a RTK (real-time kinematic) reference station(s)  171  for high-resolution GPS positioning, a cellular phone and SMS messaging system  114 , a wireless internet gateway  10 , and one or more thermally-imaging drone docking and charging airport  14  mounted above the ground surface, as shown. 
       FIG. 2  describes the primary steps involved in practicing the method of defending a wood-framed and mass timber buildings under construction using early fire-outbreak/arson-attack detection and elimination system of the present invention. 
     As shown in  FIG. 2 , the method comprises the following steps: (a) defending completed wood-framed or mass timber building sections using clean fire inhibiting chemical (CFIC) liquid spray methods on construction job sites, providing Class-A fire-protection to all defended wood; (b) installing a wireless passive infra-red (PIR) thermal-imaging fire outbreak and arson-attack sensor network  13 N within each defended wood building section in the wood building  111 A,  111 B being defended under construction; (c) deploying thermally-imaging drone aircraft vehicles  20  outside of the wood building under construction for automated deployment and capturing and transmission of thermal images of the building when a fire breaks out or arson strikes, for use by local fire department and chiefs when called to the scene of a fire or arson strike to the wood framed building; (d) deploying AI-guided and/or VR-guided thermal-imaging fire seeking and suppressing robots  40  for automated early elimination of fire detected in wood building sections of the wood building under construction; and (e) deploying AI-guided and/or VR-guided flying thermal-imaging fire seeking and suppressing drone aircraft  60  for automated early elimination of fire detected in wood building sections of the wood building under construction. 
     Once this system is installed, the follow method is practiced in accordance with the spirit of the present invention to defend wood-framed and mass timber buildings under construction using automated thermal-imaging network  13 N, and AI and VR-guided fire seeking and suppressing robot and drone systems. 
     As shown in  FIG. 36 , the method comprises: (a) using a wireless thermal imaging fire outbreak sensor network, in combination with roaming thermal-imaging fire seeking robots, to detect and locate a fire outbreak or arson attack in a wood-framed building under construction; (b) in response to automated detection of fire outbreak or arson attack by the wireless fire outbreak sensor network or roaming thermal imaging fire seeking robots, automatically generating a fire suppression command to an AI-guided or VR-guided thermal-imaging fire seeking and suppressing robots and drone vehicles; and (c) sending fire surveillance command to thermally-imaging drone aircraft so that thermal images the wood-framed building are automatically captured and this collected intelligence of thermal maps of the wood-frame building are provided to local fire department and chief called to the scene of the fire, to assist in real-time decision support on how best to respond to the particular building fire at hand. 
     This novel approach and plan for early detection and elimination of fire outbreaks and arson strikes within wood-framed and mass timber buildings is designed to work well in wood-framed and mass timber buildings in which all interior wood has been prior defended using Class-A fire-protection spray methods disclosed in Applicant&#39;s copending U.S. patent application Ser. No. 15/829,914 filed Dec. 2, 2017, incorporated herein by reference in its entirety. This novel approach to detecting and responding quickly to fire outbreaks and arson strikes will be appreciated by those skilled in the art of fighting fires in wood-framed buildings, and who understand that time is of the essence when responding to such fire outbreaks and arson strikes, due to the nature of modern wood materials and engineered wood products. 
     Typically, conventional fighting practices are not sufficiently responsive, and fire-fighting forces are not able to arrive on the scene quickly enough to eliminate fire outbreaks by arson strikes against wood-framed and mass timber building construction projects. In contrast, the approach taught by the present invention will enable a new level of responsiveness and allow construction companies, managers, and local fire departments to work with unprecedented level of efficiency and automation to detect and eliminate fires before they allowed to grow and consume the entire wood-framed building, which often times cost as high as a billion or more dollars. Expectedly, the present invention should provide significant improvements in the way fire outbreaks and arson strikes in wood-framed and mass timber buildings will be detected and eliminated during the construction phase of the building process so as to significantly reduce losses and save human lives. 
       FIG. 3A  illustrates the method of and system for the present invention for on-job-site spray-coating clean fire inhibiting liquid chemical (CFIC) liquid over all exposed interior surfaces of raw as well as fire-treated lumber and sheathing used in a completed section of a wood-framed building during its construction phase, disclosed in U.S. patent Ser. No. 15/874,874 filed Jan. 18, 2018, Ser. No. 15/866,456 filed Jan. 9, 2018, Ser. No. 15/866,454 filed Jan. 9, 2018, and Ser. No. 15/829,914 filed Dec. 2, 2017, wherein each said US patent application is incorporated herein by reference. As shown, a GPS-tracked mobile clean fire-inhibiting chemical (CFIC) liquid spraying system  101 , and the system network illustrated in  FIG. 8 , are used to apply and document the spraying of a thin CFIC film or coating over all exposed interior wood surfaces, and thereby provide Class-A fire-protection over all lumber and sheathing used in the wood-framed building construction, along with a complete chain of evidence and documentation to qualify the owner of the Class-A fire-protected wood-framed building for lower fire insurance premiums, and provide local fire departments with valuable building information when fighting fires that may break out in such Class-A fire-protected wood-framed buildings.

     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 wood-framed 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. 51A  illustrates a first job-site of multi-apartment wood-framed building under construction prepared and ready for clean fire inhibiting chemical spray coating treatment in accordance with the principles of the present invention.  FIG. 51B  illustrates a second job-site of multi-apartment wood-framed building under construction prepared and ready for 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 wood-framed 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.

     As indicated at Block A in  FIG. 11A , after a builder completes each predetermined section of a wood-framed 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 wood-framed building. 
     As indicated at Block B in  FIG. 11A , when the completed section of the wood-framed building is spray coated with CFIC liquid, the completed wood-framed building section is certified and marked as certified, with a posted barcoded/RFID-tagged certification of inspection  300  (at inspection checkpoints), then certified and verified with signatures by the spray applicator and on-site manager, and digitally documented by scanning and data capturing as shown in  FIGS. 51A and 51B , and uploading to the system network server  113 A, for subsequent visual inspection and insurance documentation purposes. 
     As indicated at Block C in  FIG. 11A , as each section of the wood-framed 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  300  at posted inspection checkpoints, 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. 11B , the spray technician then issues a time/date stamped “certificate of completion” with respect to the application of clean fire inhibiting chemical (CFIC) liquid to all exposed wood surfaces on the interior of the wood-framed building during its construction phase, thereby providing the wood-framed building with Class-A fire-protection and defense against risk of total destruction by fire. 
     As indicated at Block E in  FIG. 11B , before applying gypsum board and/or other wall board covering over the fire-protected spray-coated wood-framed building section  118 , the mobile application  120  on mobile computing device  117  is used to capture and collect digital photographs and/or videos showing barcoded/RFID-tagged inspection checkpoints  300  (with integrated signed certificates of spraying and inspection) posted on spray-coated fire-protected sheathing and/or lumber used in the wood framing of each completed building section as shown in  FIGS. 13 and 14 , and signed by the spray technicians and spray supervisor, 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 wood-framed 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 wood-framed 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. 11B , 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. 11B , archiving all photographic and video records collected during Block F and uploading to the centralized web-based information server  111  at Block G for best practice and legal compliance purposes. 
     As indicated at Block H in  FIG. 11A , 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 (i) visually document the spraying of CFIC liquid over all exposed interior wood-surfaces of a wood-framed building under construction so as to achieve Class-A fire-protection, and (ii) after certifying with signatures, the proper on-site spray application of CFIC liquid, and Class-A fire-protection treatment of the wood-framed building, to 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 which such uploaded and archived digital 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  of the present invention, 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 wood-framed 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 Wood-Framed 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 wood-framed 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. 12A through 14 . 
       FIG. 12A  is a schematic representation of an architectural floor plans for a wood-framed building scheduled to be sprayed with CFIC liquid to provide exposed interior surfaces with Class-A fire-protection. 
       FIG. 12B  is a schematic representation of architectural floor plans for a wood-framed building, with a section marked up by the builder, and scheduled to be sprayed with CFIC liquid to provide Class-A fire-protection. 
       FIG. 12C  is a schematic representation of 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. 
       FIG. 12A  shows architectural floor plans for a wood-framed 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. 12B  shows architectural floor plans for an exemplary wood-framed 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. 12C  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 will be supported and use the mobile application  120  (or web-browser equivalent) during a spray project on a building construction site for the following 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 (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. 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. 62A . 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, etc.) shown be posted during the project, as shown in  FIGS. 62 and 63 , 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 liquid 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 wood-framed 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 protector 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 wood-framed building to be spray-treated with CFIC liquid spray, indicated in  FIG. 13 . Each RFID tag and/or bar code symbol will be encoded with an unique code identifier that is marked on the floor plan, and uniquely associated with the project, and added to the network database  113 A on the system network. 
     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. 13 , 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 wood-framed building section under inspection. 
     As illustrated in  FIG. 14 , rich barcoded/RFID-tagged inspection checkpoint  300  will include a bar code symbol and RFID tag 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 wood-framed 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  FIGS. 13 and 14 . 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. 
       FIG. 13  shows a wood-framed door panel showing the studs and header above a doorway, on which the barcoded/RFID-tag encoded inspection checkpoint of the present invention  300 , realized on a piece of thin flexible plastic material and supporting a barcode symbol and RFID-tag encoded to the spray project at hand, and bearing printed certifications by a spray technician and spray supervisor, and optionally by the building site superintendent shown in greater detail in  FIG. 14 . 
       FIG. 14  shows the barcoded/RFID-tag encoded inspection checkpoint shown in  FIG. 13 , with integrated certifications by spray technician liquid and spray supervisor, and optionally, the building site superintendent. 
     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, 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, but with the spray technicians markings 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 visit each checkpoint and read, sign and date the certificate of inspection/oversight by the building superintendent 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, 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 (3 for spray administrator and 3 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. The spray technician will certify that he has provided the first set of sprayed test samples in storage sleeves to the building site superintendent, and the second set of sprayed test samples to the spray site superintendent. The building site superintendent will sign that he has received the sprayed test samples in their barcoded storage sleeves. The second set of sprayed test samples can be shipped to the fire protection provider&#39;s warehouse for archival purposes. 
     Method of Qualifying a Wood-Framed 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 Wood-Framed Building During the Construction Phase Thereof 
       FIG. 15  describes the method of qualifying real property for reduced property insurance, based on verified on-site spraying of the exposed interior surfaces of wood-frame buildings with clean fire inhibiting chemical (CFIC) liquid during the construction stage of the building, using the system network of the present invention. 
       FIG. 15  shows the high-level steps required to practice the method of qualifying a wood-framed 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 wood-framed building, after each completed section. 
     As indicated at Block A in  FIG. 15 , a clean fire inhibiting chemical (CFIC) liquid is sprayed all over all interior surfaces of each completed sections of a wood-framed building to provide Class-A fire-protection, as described above in  FIGS. 3 through 13 , using the GPS-tracked/GSM-linked mobile clean fire-inhibiting chemical (CFIC) liquid spraying system  101 , shown in  FIGS. 3 through 13 . 
     As indicated at Block B in  FIG. 15 , 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 spray system  101  deployed on the system network, and (ii) digital images, and audio-video (AV) recordings of barcoded/RFID-tagged certificates of inspection  300  posted on completed sections after spray treatment, as illustrated in  FIGS. 3 and 13 , and  FIGS. 13 and 14 , using the mobile application  120  on mobile computing device  120 . 
     As indicated at Block C in  FIG. 15 , the collected on-site spray treatment verification data is wirelessly transmitted to a central network database  113 A on the system network to update the central network database on the system network  109 . 
     As indicated at Block E in  FIG. 15 , a company underwriting property insurance for the wood-framed building accesses the central network database  113 A on the system network, to verify the database records maintained for each wood-framed 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 wood-framed building. 
     As indicated at Block E in  FIG. 15 , upon the outbreak of a fire in the insured wood-framed building/property, the local fire departments instantly and remotely assess the central network database  113 A using a mobile application  120 , so as to quickly determine Class-A fire-protected status of the wood-framed building by virtue of CFIC liquid spray treatment of the wood-framed building during the construction phase, and inform fireman tasked with fighting the fire that the wood-framed building has been treated with Class-A fire-protection defense against fire. 
     Specification of the Network Architecture of the System Network of the Present Invention 
     As shown in  FIG. 8 , the Internet-based system network  1  is shown comprising various system components, including an cellular phone and SMS messaging systems  114 , and one or more industrial-strength data centers  110 , preferably mirrored with each other and running Border Gateway Protocol (BGP) between its router gateways, and each data center  110  comprising: a cluster of communication servers  112  for supporting http and other TCP/IP based communication protocols on the Internet; cluster of application servers  17 ; a cluster of email processing servers  115 ; cluster of SMS servers  114 ; and a cluster of RDBMS servers  113  configured within an distributed file storage and retrieval ecosystem/system, and interfaced around the TCP/IP infrastructure of the Internet  116  well known in the art.

     Specification of Database Schema for the Database Component Used on the System Network of the Present Invention 
     During the design and development of the system network, a data schema will be created for the object-oriented system-engineered (DOSE) software component thereof, for execution on a client-server architecture. In general, the software component of the system network will consist of classes, and these classes can be organized into frameworks or libraries that support the generation of graphical interface objects within GUI screens, control objects within the application or middle layer of the enterprise-level application, and enterprise or database objects represented within the system database (RDBMS)  113 . Preferably, the RDBMS will be structured according to a database schema comprising enterprise objects, represented within the system database (e.g. RDBMS), and including, for example: building owner; building manager; building insurer; system user ID; building ID, building location; building property value; vehicle ID for unmanned VR-guided fire fighting robot system; vehicle ID for identifying each unmanned thermal imaging aircraft system deployed on the system network; client device ID for identifying each VR-enabled building navigation and control device deployed on the system network; client workstation ID for identifying each VR-enabled computer workstation deployed on the system network for remotely controlling one or more deployed unmanned VR-guided fire thermal imaging aircraft systems; client workstation ID for identifying each VR-enabled computer workstation deployed on the system network for remotely controlling one or more unmanned VR-guided fire fighting robot systems; and many other objects used to model the many different aspects of the system being developed. 
     These objects and the database schema will be used and reflected in a set of object-oriented software modules developed for the system. Each software module contains classes (written in an object-oriented programming language) supporting the system network of the present invention including, for example, the user registration module, unmanned VR-enabled fire fighting system registration module, remote VR-enabled control-station registration module, hand-held building navigation/inspection system registration module, user account management module, log-in module, settings module, contacts module, search module, data synchronization module, help module, and many other modules supporting the selection, delivery and monitoring of building-related services supported on the system network of the present invention. 
     Different Ways of Implementing the Client Machines and Devices on the System Network of the Present Invention 
     In one illustrative embodiment, the enterprise-level system network of the present invention is supported by a robust suite of hosted services delivered to (i) Web-based client subsystems  117  using an application service provider (ASP) model, and also to (ii) unmanned VR-guided thermal imaging aircraft systems  20 , (iii) unmanned/flying AI/VR-guided fire fighting robotic systems  40 , and (iv) remotely-situated VR-enabled control-stations  80  for remotely controlling unmanned VR-guided fire fighting robot and drone systems as well as unmanned VR-guided thermal imaging aircraft systems  20 , described above. 
     In this embodiment, the Web-enabled mobile clients  117  can be realized using a web-browser application running on the operating system (OS) of a computing device (e.g. Linux, Application IOS, etc), to support online modes of system operation. It is understood, however, that some or all of the services provided by the system network can be accessed using Java clients, or a native client application running on the operating system (OS) of a client computing device to support both online and limited off-line modes of system operation.

As shown, the mobile device can include a memory interface, 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. One or more communication buses or signal lines can couple the various components in the mobile device. 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  8 B,  8 C is intended to operate. For example, a mobile device  100  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 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.

     Specification of the Wireless Network of Passive Infra-Red (PIR) Thermal-Imaging Fire Outbreak and Arson Attack Sensor Network Deployed in Each Class-A Fire-Protected and Defended Section of a Wood-Framed and Mass Timber Building 
       FIG. 20A  shows the wireless network of passive infra-red (PIR) thermal-imaging fire outbreak and arson attack sensor network  13 N of the present invention deployed in a wood-framed or mass timber buildings under construction. As shown in  FIGS. 20B, 20C and 20D , each PIR thermal imaging sensor  13  comprise; various components arranged and configured about a microprocessor and flash memory (i.e. control subsystem), including: one or more passive infra-red (PIR) thermal-imaging sensors connected together with suitable IR optics to project IR signal reception field of view (FOV) before the IR receiving array; a GPS antenna; a GPS signal receiver; voltage regulator; an Xbee antenna; an Xbee radio transceiver; a voltage regulator; an external power connector; a charge controller; a battery; thermistors; a power switch; a voltage regulator; external and internal temperature sensors; power and status indicator LEDs; programming ports; a digital/video camera; and other environment sensors adapted for collecting and assessing building intelligence, in accordance with the spirit of the present invention. In the illustrative embodiment, the fire outbreak detection system has a computing platform, network-connectivity (i.e. IP Address), and is provided with native application software installed on the system as client application software designed to communicate over the system network and cooperate with application server software running on the application servers of the system network, thereby fully enabling the functions and services supported by the system, as described above. In the illustrative embodiment, a wireless mess network is implemented using conventional IEEE 802.15.4-based networking technologies to interconnect these wireless subsystems into subnetworks and connect these subnetworks to the internet infrastructure of the system of the present invention. 
       FIGS. 20CA ,  20 C 2  and  20 C 3  show three different variable optics field that can be supported for motion detection and thermal-imaging within the wireless PIR thermal imaging sensor  13  of the present invention shown in  FIG. 20B . 
     FIG.  20 C 1  illustrates the long-range optics supported within the wireless PIR thermal-imaging fire-outbreak and arson-attack sensing module of  FIG. 20B , along with GPS-tracking and GPS/time/date-stamping, for monitoring narrow areas including corridors for thermal activity and motion. 
     FIG.  20 C 2  illustrates the curtain optics supported within wireless PIR thermal-imaging fire-outbreak and arson-attack sensing module of  FIG. 20B , along with GPS-tracking and GPS/time/date-stamping, for monitoring possible intrusion locations for thermal activity and motion. 
     FIG.  20 C 3  illustrates the area optics supported within the wireless PIR thermal-imaging fire-outbreak and arson-attack sensing module of  FIG. 20B , along with GPS-tracking and GPS/time/date-stamping, for monitoring particular areas with specific ranges for thermal activity and motion. 
     Preferably, the optics of the motion and thermal activity sensor  13  is constructed so that the installer can easily select the desired IR optics for the specific motion sensing application at hand—e.g. by selecting a manual externally located optics selector switch provided on the sensor housing, to configure a specific optics arrangement for the sensor in a specific completed section of the wood-framed building. However, in the alternative, several different sensors can be manufactured, each having different IR optics for a specific thermal and motion sensing application at hand, which are selected for use during the installation process. In general, installation of thermal-imaging motion sensors is an ongoing and incremental process as Class-A fire-protection spraying is performed throughout the entire building. As this fire protection process continues, so too does the extension of the wireless thermal-imaging and motion sensing network  13 N of the present invention, with the addition of a few additional sensors as each additional section of the building is defended with Class-A fire-protection liquid spray treatment, as described in  FIGS. 2 through 13 . As this wireless sensor network is extended, additional wireless network routers will be added to extend the range of the wireless network. 
     Preferably, the optical bandwidth of the IR sensing array used in the thermal and motion sensor  13  of the present invention will be adequate to perform thermal activity analysis operations be simple motion detection, required of any PIR-based motion sensor. Specifically, thermal sensing in the range of the sensor should be similar to the array sensors installed in forward-looking infrared (FLIR) cameras, as well as those of other thermal imaging cameras, use detection of infrared radiation, typically emitted from a heat source (thermal radiation) such as fire, to create an image assembled for video output and other image processing operations to generate signals for use in early fire detection and elimination system of the present invention. 
     In a less preferred embodiment, one can adapt and modify a PIR motion sensor such as the Honeywell Viewguard PIR Motion Detector (Item Nos. 033435 and 033434) or similar PIR sensor product, to produce the GPS-tracking PIR thermal-imaging motion sensor  13  that outputs the GPS coordinates of the installed sensor and time and data stamping information with thermal image(s) that triggered the specific threshold motion detection algorithms used to detect motion and/or suspicious thermal activity, within the image processing capabilities of the sensor. This motion triggering information will be provided to the surveillance and fire security information servers maintained on the system network  1  for automatically generating and issuing the necessary commands to (i) deployed thermal-imaging drone systems  20 , (ii) deployed thermal-imaging fire seeking and suppressing robot systems  40 , and (iii) deployed thermal-imaging fire seeking and suppressing drone aircraft vehicles  60 . 
     In general, most streams of digital intelligence captured by the wireless PIR thermal-imaging FLIR sensor network will be time and data stamped, as well as GPS-indexed by a local GPS receiver within the sensing module, so that the time and source of origin of each data package is recorded within the system database. The GPS referencing system supporting the system transmits GPS signals from satellites to the Earth&#39;s surface, and local GPS receivers located on each networked device or machine on the system network receive the GPS signals and compute locally GPS coordinates indicating the location of the networked device within the GPS referencing system. 
     When practicing the wireless network of the present invention, any low power wireless networking protocol of sufficient bandwidth can be used. In one illustrative embodiment, a Zigbee® wireless network would be deployed inside the wood-framed or mass timber building under construction, so as to build a wireless internetwork of a set of wireless PIR thermal-imaging fire outbreak detection systems deployed as a wireless subnetwork deployed within the building under construction. While Zigbee® technology, using the IEEE 802.15.1 standard, is illustrated in this schematic drawing, it is understood that any variety of wireless networking protocols including Zigbee®, WIFI and other wireless protocols can be used to practice various aspects of the present invention. Notably, Zigbee® offers low-power, redundancy and low cost which will be preferred in many, but certainly not all applications of the present invention. In connection therewith, it is understood that those skilled in the art will know how to make use of various conventional networking technologies to interconnect the various wireless subsystems and systems of the present invention, with the internet infrastructure employed by the system of the present invention.

     Modifications of the Illustrative Embodiments of the Present Invention 
     The present invention has been described in great detail with reference to the above illustrative embodiments. It is understood, however, that numerous modifications will readily occur to those with ordinary skill in the art having had the benefit of reading the present disclosure. 
     The illustrative embodiments disclose the use of clean fire inhibiting chemicals (CFIC) from Hartindo Chemicatama Industri, particular Hartindo AAF21 and AAF31 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. 
     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. 
     These and all other 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.
