The method of anchoring was to shot-pin a 2x4 to the concrete and nail a 2x4 on top of the pinned 2x4, an angle brace was then nailed to the side of the top 2x4.  This method was done approximately every 8\u2019-10\u2019.  See attached photo. \nThe work was self-performed by PBG, so all liability was solely held by PBG.\nWindy day with gusts in excess of 40mph.\nThe temporary fence was constructed between two adjacent buildings that create a wind tunnel affect, The fence was reconstructed with additional bracing and utilizing concrete stakes drilled into the sidewalk, How will you ensure that all temporary fencing is securely anchored to existing structures and that it will be sufficient to withstand high wind conditions or other circumstances that could result in dislodging it?\n01 56 29 Temporary Protective Walkways, Pre-Construction, Proposal, nan, nan, \tHave temporary protective walkways been identified as necessary during the development of the project's proposal?\n01 56 29 Temporary Protective Walkways, Pre-Construction, Budget, nan, nan, \tDid you ensure to have enough money in the project's budget to build covered walkways, if required?\n01 56 29 Temporary Protective Walkways, Pre-Construction, Budget, nan, nan, \tDid you include money in the budget for replacement/reconstructions costs that may arise from removing the temporary protective walkway?\n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, nan, \tDid you review the AHJ requirements that need to be followed regarding protective walkways?\n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, Requirements/Guidelines:\n\nLet\u2019s talk about when pedestrian walkways are required.  In the past this has been kind of grey area, but you must start with your main CC Building Inspector.  It\u2019s better to ask them out of the gates what they want to see, in lieu of getting a notice of violation days before your walkway needs to be constructed.  If your building permit is under IBC 2006, refer to Section 3306 page 538 of the IBC 2006 Book.  Table 3306.1 will give you the requirement guidelines to follow.  This table is also important to review during bid time.  Make sure we get enough money in the budget for covered walkways if required under Table 3306.1. \n\nPermitting:\n\nEncroachment Permit:  You must apply with CC Civil Engineer Department for this permit.  A traffic control plan must accompany your application (Contact Superior Traffic Services for documents).  This plan shows where you intend on temporarily diverting pedestrian traffic in order to install the scaffold system.  Don\u2019t start installation until this permit is in hand.  Also required is 3 Engineered stamped copies of the scaffold drawings and structural calculations.\n\nTraditionally you would receive a one month permit for the sidewalk closure.  However, in recent months, the Civil Department is issuing permits in 6 month intervals.  Most of the time your scaffold system will be required for a large majority of the construction project and the Civil Department wants to have input for that duration.  Upon disassembly of the scaffold system, Civil will now require a final inspection to insure the contractor has not damaged the sidewalk/curb/asphalt/etc.  Be sure to capture R&R cost for the inevitable damage.\n\nBuilding Permit:  You will also need a Building Permit through CC Development Services Building Division.

So here goes, you must inform the Engineer that generates the scaffold drawings that he/she needs to include as much information on the drawings as possible.    Rule of thumb:  The onsite building inspector should be able to look at the drawings and inspect every square inch of the system based on a super detailed drawing.  What does this detail include?  This is just a start, but the following information must be on the plans:\n\nICC-ES Report Numbers for Concrete Anchors (Use Hilti QuickBolt KB-TZ per ESR-1917 which is IBC 2006 compliant)\nGeneral Structural notes and material callouts: plywood, aluminum size, bolts, screws, clips etc.\n All connection points must have detail blowups (ex. Joist, Du-Al Bms, Outer legs, Ledgers, etc.)\nAll framing member sizes, thickness and gauges shall be clearly identified on plans.\n\nIn regards to the structural calculations, the following at a minimum must be provided:\n\nUniform loads, moment/shear for joist and stringers.\nTributary area, plywood load, joist load, wind uplift resistance.\nSill design and calculations.\nAll material specifications.\n\nOnce you have received the Building Division Permit you must contact your onsite building inspector for an inspection after scaffold installation is complete.  Make sure you have installed the system per the approved plans.\n\nSummary:\n\nReview Section 33 of 2006 IBC Code Book.\nTalk with your onsite inspector if you think a covered walkway may be needed.\nHave the scaffold company generate a super detailed set of plans.  Contact CC Structural Reviewers for permit acceptance criteria (see contact below)\nSchedule a meeting with CC review team prior to submitting to ensure plan compliance.\nImmediately apply for Encroachment and Building Permits once plans and structural calculations are completed.\nOnce Permits are received, install scaffold system and call for CC Building Inspection.\nMaintain the system for structural integrity and safety items.\nOnce the scaffolding is no longer needed per CC, dismantle, call Civil for inspection and close out both permits., \tDid you include a traffic control plan and the necessary number of copies of stamped drawings when applying for an Encroachment Permit required for the protective walkway scaffold system?\n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, nan, \tDid you ensure that the Engineer or Subcontractor that designed the temporary protective walkway provided as much information as possible on the drawings being submitted for permits to the AHJ? \n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, nan, \tDo you have an approved permit before erecting the temporary protective walkway?\n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, nan, \tHave you asked the AHJ Inspector what they would like to see be built as a protective walkway?\n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, nan, \tDid you schedule the final inspection from the AHJ to ensure that there was no damage done to either the existing sidewalk, curb, asphalt,", "doc_id": "21f6c15e-b857-4d1a-89af-42f42cf018ab", "embedding": null, "doc_hash": "5def0368845274d9aa66b07010240dd33a9eeb16ff748fec5648e7b7724aa617", "extra_info": null, "node_info": {"start": 3350, "end": 7353}, "relationships": {"1": "156b72e7-39f7-4575-9d7a-72cb373ed099", "2": "7f2b61df-113c-4458-8a17-2e9acb69e3eb", "3": "3f19ab44-1c6a-4174-8cf4-2711956ce6c9"}}, "__type__": "1"}, "3f19ab44-1c6a-4174-8cf4-2711956ce6c9": {"__data__": {"text": "nan, \tDid you ensure that the Engineer or Subcontractor that designed the temporary protective walkway provided as much information as possible on the drawings being submitted for permits to the AHJ? \n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, nan, \tDo you have an approved permit before erecting the temporary protective walkway?\n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, nan, \tHave you asked the AHJ Inspector what they would like to see be built as a protective walkway?\n01 56 29 Temporary Protective Walkways, Permits and Inspections, nan, nan, nan, \tDid you schedule the final inspection from the AHJ to ensure that there was no damage done to either the existing sidewalk, curb, asphalt, etc. when the temporary protective walkway was removed?\n02 00 00 Existing Conditions, Construction, nan, During the excavation of a mat foundation the earthwork contractor hit a high voltage Nevada Power Conduit bank on site.

The all-thread was assumed to be sufficiently anchored to the pan deck above the finished ceiling but became unsecured and fell through the ceiling narrowly missing a Mumfresh employee.  There were numerous hangers, metal studs, and construction debris left in the ceiling after demolition.  These items were not removed because they were deemed either safe or there was no apparent reason for their removal.  During demolition operations, any type of hanger, metal stud, or construction debris that is not directly supporting the new construction or existing utilities/infrastructure should be removed to prevent such objects/materials from becoming a struck-by hazard. , Excess materials should be removed and not abandoned above the finished ceiling. , \tDid you remove excess or unnecessary materials (e.g., hangers, metal studs, construction debris) that are not directly supporting the new construction or existing utilities/infrastructure to avoid such objects from falling and becoming a struck-by hazard?\n03 00 00 Concrete, Construction, nan, The F-Number System is the American Concrete Institute and Canadian Standards Association standard for the specification and measurement of a concrete floor flatness and levelness.

In many cases, the contract documents will call for the contractor to measure the flatness of a concrete floor placement to a specific F-Number specification.  During the course of the project, it may happen that the owner or owner\u2019s rep gives approval to skip the measurement of the concrete floor.  This is not acceptable.  If the contract documents call for the concrete floor to be measured against the F-Number system than PBG must measure the floor regardless of any decisions made to the contrary during the course of the project.  We have been burned during the post construction/warranty phase when this is not done.  If there is a problem with the floor after construction, the owner expects PBG to resolve the issue and points at the requirement in the contract document to emphasize why it is PBG\u2019s responsibility.  The argument that the specification was waived during construction has not been enough to alleviate PBG\u2019s responsibility in this case.  Concrete floors that are required by the contract documents to be measured against the F-Number System have not been measured based on Owner, Owner Rep, and PBG team decisions during the course of the project.  This decision has come back as an issue for us during post construction., If the contract documents call for the concrete floor to be measured for flatness than measure the floor for flatness regardless of decisions made by he Owner during the course of construction., \tWas the concrete floor measured for flatness and levelness using the American Concrete Institute's F-Number system to meet contract specifications?  This should be done regardless of the Owner or Owner Representative's wishes to not do this.\n03 00 00 Concrete, Construction, nan, During construction of the restaurant venues we had problems achieving concrete floor flatness / levelness due to the abundance of utility stub ups.  The concrete slabs were poured using a laser level to establish grade pads at approximately 10\u2019 by 10\u2019 intervals.  We then used a hand screed between these pads.  This method of placement left us with incorrect finish elevations and a floor flatness / levelness not within tolerances.  The most problematic areas occurred around utility stub ups., By boxing out and cutting down the utilities we were able to cap them 1\u201d below the concrete finished surface.  Our hand screed method was more effective without the numerous obstructions.  This solution would also give us the option of using a laser screed to achieve a more precise slab.  A second benefit of boxing out and capping the utilities is they are now protected from equipment traffic.  In areas where we didn\u2019t use this method we had to replace / fix most of the stub ups due to equipment damage.  By boxing and capping we could have saved the time and cost of repairs, Were the utility stub ups boxed up and capped 1 inch below the concrete finish surface to allow for a laser screed to be used which would result in a more precise flat/level slab?\n03 00 00 Concrete, Construction, nan,  There are two sequences for incorporating upturned beams into a project schedule.  One sequence is to keep the area of the upturned beam shored until re-shores are no longer required for subsequent deck pours at which time you would form, pour and stress the upturned beam.

Did you review them with all Foremen and trade workers?\n03 00 00 Concrete, Project Startup, Constructability Review, By default, structural concrete specifications typically call for concrete tests to meet both a 28-day break and a minimum strength (ex. 4000 psi) requirement.  In many cases this minimum required strength can be met with a 12 to 14 day break.  Even so, we are still unable to obtain a 3rd party final inspection since the break does not meet the 28-day specification requirement.  While this is typically not an issue in other markets, on some of the fast tracked, shorter duration projects that PBG does, waiting the additional time for the last structural pour to meet the 28-day break requirement and then submitting the 3rd party final test results to the county may delay obtaining the CofO.  28-day break specification requirement for structural concrete may cause schedule issues on fast track, shorter duration projects., Determine if this is an issue at the beginning of the project and work with the Architect to modify the structural concrete specifications to require a 12 or 14 day break provided that the test still meets the minimum strength requirement., \tTo avoid delays, can the 28-day break and minimum strength requirement typically called for in the structural concrete specifications be modified by the Architect at the beginning of the project for a 12- or 14-day break instead?\n03 00 00 Concrete, Buyout, nan, On the tower at Aliante there is an 18\u201d concrete projection that extends beyond the EIFS / Glazing system (Building Envelope).

Since, typically, a spiral staircase is part of a much larger structural package; the structural steel subcontractor may simply include a number for it in their bid and assume they can find a subcontractor that makes stringers after they get the job.  The problem is that there are only a few companies that fabricate spiral staircase stringers.\n\nPBG ran into this issue on the RIO Voodoo Lounge project.  The solution we found is a steel fabrication company in Niagara Falls, Canada named Hodgson Custom Rolling, Inc (Hodgson).  Hodgson is a fabrication shop that is heavily involved in rolling, forming, and bending steel plate and is known for fabricating stringer components and handrails.  They are part of a very small niche of companies that offer this specialty service and may be a useful resource to PBG on future projects.\n\nMore detailed information describing Hodgson Custom Rolling, Inc. is attached to this bulletin.\n\nPROBLEM\n\nThere are few steel fabricators that are able to handle the specialized fabrication involved with spiral staircase stringers.\nMany structural steel subcontractors may under estimate the difficulty of finding a fabricator that can make spiral staircase stringers when bidding the project, PBG found a fabricator in Niagara Falls, Canada that specializes in spiral staircase stringer and handrail fabrication.

The wood sub-top was MDF with Melamine applied to the top surface (trade name \u201cKortron\u201d) the troughs were inserted into openings that were cut into the sub-top. The edges of these cut openings were not sealed. When the edges were exposed to water the wood started to swell causing a warping affect in-turn causing the stone top to crack and lift. We know water was the source of the problem and we also know that ice is being used in these trough (see photo #7) but we could not figure out where the large quaintly of water was coming from that would cause the top to fail so quickly. We decided to do some early morning investigation about 2:00 a.m. to watch how the in-house cleaning staff cleans the Buffet; this is where we found our water source.

There must be stainless steel framing applied to the trough cut-out edges (see photo #17). The stainless steel framing must be applied with silicone to add an extra barrier between the wood edge and the stainless steel. There should also be a good solid bead of silicone applied around the trough where it meets the stone also sneeze guard base plates should be imbedded in silicone to keep water from entering through the screw holes.(see photo #18). The cut-out inside corners of the stone top should be rounded and not straight cut, this process should help the stone from cracking from the corners, \tIs marine grade plywood being used as the sub-top of the buffet/salad bar?

During Super Bowl weekend, managers in the semi-private dining room were throwing prizes (shirts, etc.) to patrons on the balcony.  A man on the balcony hit a wooden panel beneath the railing with his knee while lunging for a prize; causing the panel to come loose.  The panel fell 8' to the floor below and hit a manager above the eye; requiring the manager to receive a number of stitches.  The wooden panels, in a stainless steel frame, were originally shown fastened to the frames with a mechanical fastener on the shop drawings.  The Owner requested an alternate fastening method that would allow the panels to be easily removed when worn, so PBG, at the Owner\u2019s request, used silicone to fasten the panels into the frames.  In the future, to avoid any similar incidents, all such decorative panels within guardrails that will be used in public areas must be fastened with a mechanical fastener or weld.\n\nPROBLEM\n\nThe fastening method for the decorative panels within the guardrails on the balcony at the RIO All American Grill was changed from mechanical fasteners (shown on the shop drawings) to silicone at the request of the Owner.

We sent through an RFI asking if the walls needed to be rated, but the architect thought that because the walls were on the roof, they would be considered exterior and therefore non-rated.  We sent through another RFI to confirm that no walls were rated and after further review by the architect the response came back that the elevator machine rooms and the framed portion of the elevator shafts would need to have two hour rated walls and a 1 \u00bd hour rated ceiling.  We built the walls according to the RFI response, but the response was only partially accurate.  The walls and ceiling that frame the top of the stair towers on the roof also needed to be rated., Our lesson learned is to review with the architect in detail what rooms need to be protected in case of a fire.  In our case, it was decided to rate the elevator machine rooms, elevator shafts, stair towers, and emergency electrical room so that in the case of a fire or explosion the integrity of those rooms would be maintained.  RFI responses addressing fire ratings should include confirmation from the architect and life safety consultant, \tDid you review with the architect, and the life safety consultant, in detail what rooms need to be protected in case of a fire, including elevator machine rooms, elevator shafts, stair towers, and emergency electrical rooms? \n07 00 00 Thermal and Moisture Protection, Pre-Installation, Constructability Review, At WMC, the designer did not want to waterproof the top deck of the garage.

While the official cause is still being debated it appears that excessive moisture trying to escape the Densglass / EIFS product may have reacted with acrylic components of the EIFS and left a surface contaminant.  Fortunately, this problem is not present on PBG\u2019s Convention Expansion project which uses a framed exterior rather than a panelized system.  The magnitude of this problem, including removal and new prep, could be significant.\n\nThe current suggested solution going forward is that Dow Corning 790 (and primer \u201cP\u201d) be used in place of the GE Silicone on any project with Dryvit EIFS.  As a rule, any project with substantial caulking packages should have CDC involved as a consultant to review the system.  CDC should also be used to observe the initiation of the caulking pull test to make sure that there are not any issues and that the test is conducted correctly. \n\nSecondly, PBG standard process is to buyout the caulking package underneath the EIFS subcontractor.  This places the responsibility for success on a single subcontractor and eliminates any finger pointing issues if there is a problem with either the caulk or the EIFS.  The EIFS subcontractor can\u2019t blame the caulker and vice versa.  PBG also requires that all EIFS subcontractors be bonded so that we are covered if there is ever a problem on a PBG project.\n\nPROBLEM\n\nThere is a product problem with GE Silicon sealant and Dryvit coating at Caesars Palace Tower.

These gates were large and then to add to the problem the owner decided that they wanted one of the gates clad so that you couldn\u2019t see through it, Make sure that all gates are engineered prior to pouring concrete. You need to look closely at the gate post footing because it is most likely next to a CMU wall and the footing for the gate post will interfere with the footing for the CMU wall.\n\nSuggestions: \n\n1.) You may want to have the gate engineered as a solid gate just in case the Owner/ Architect decides that they don't want to see through it. The wind load on a solid gate is very large and the post and footing for a non solid gate WILL NOT work if this gate is changed to a solid gate.\n\n2.) It has been suggested to embed weldable rebar in the adjacent CMU or Concrete wall. This rebar can be welded to the back of the gate post to help with deflection.

Our door submittal went in for review and was approved without comments for the guestroom connecting doors. It was later discovered that the life safety report differed from the drawings and indicated that the connecting doors needed to be 45min.  The architect argued that two 20min. doors would be adequate to maintain the 1 hour fire separation; however, the life safety engineer did not. It was decided in the end to change out all the 20min. doors to 45min. doors, Our lesson learned is that two 20min. doors do not have the same fire rating as a 45min. door.  Additionally, both connecting doors need to be 45min. doors because one of the two doors could be left open by a guest.

The distance from the edge of slab to the backside of the exterior CW system varied from approx 5\u2019-12\u2019which made it impossible to use a traditional edge of slab firesafing assembly.  Each floor was a separate smoke zone based on the smoke control plans and therefore could not communicate with each other.  After much discussion with the City inspectors and plans checkers they decided that the interior walls that were adjacent to this void area needed to be rated and have TOW firesafing to get the rating from floor to ceiling and isolate the void space from the smoke zones.  This involved approx 300LF of shaft wall and TOW firesafing and a drawings revision to the permit set of plans before the city would sign off on the walls in the field., Verify and understand all voids that occur as a result from exterior cladding geometry and how it affects the smoke control system and fire ratings.

They had already installed most of the run of pipe the day before and had just a few more fittings to install at the \u201cHigh\u201d end of the underground on that morning. The area of the pipe that was freshly glued was approximately 30 ft. away from where the incident causing the explosion occurred.\n\nAbout an hour and \u00bd after they glued the last fitting, a plumber began cutting metal studs with a cutting torch near the \u201cLow\u201d end of the run of pipe (2% slope).  Sparks flew into a 2\u201d inch riser for a floor sink in the run of pipe where, apparently, the vapor from the glue had settled.  The sparks ignited the fumes and created a very large explosion. The pipe consisted of schedule 40 thicknesses and, even where the couplings were attached, was shattered into pieces of approximately \u00bd inch in size.  There were also 6 open ends of pipe throughout the run with no caps installed and even where the pipe had a \u201cY\u201d fitting it blew out at the 90 on every fitting installed. Fortunately, no one was injured even though people were working in very close proximity to the blast.\n\nThis type of explosion is rumored to have happened once before on a job with a 10\u201d inch line and the Clark County Fire Department apparently made a statement at that occurrence that they had never seen this happen before either!\n\nPROBLEM\n\nGlue fumes that accumulate inside a new piping run have the potential to ignite and cause a large explosion, Keep new plumbing area clear of any open flame/sparks until pipe glue has had sufficient time to dry and fumes have dissipated.  Always wear safety glasses when in new piping area to protect eyes in the event of an explosion, \tIs the area surrounding a newly installed pipe free and clear of any open flame/sparks and have the pipe glue fumes been given sufficient time to dissipate?

Zone \u2018D\u2019 requires ALL MEP installation to be seismic restrained.  Based on this designation the cost for the Seismic bracing for plumbing and mechanical was projected at $1.75M.  Additionally the building was not designed for Zone \u2018D\u2019 and it would have been impossible to meet the Zone \u2018D\u2019 requirements without redesign of the system which would have created a schedule delay.  After researching the issue Hansen discovered that the project was actually located in Zone \u2018C\u2019 per the Structural drawings, this reduced the cost to $350,000 and no re-design would need to occur., Seismic restraints have been a code requirement since the adoption of UBC 2000.  At that time the code was not being enforced since the building department did not have the expertise to inspect the system.  The 2006 code added language that a Third Party Consultant could inspect the seismic restraints on the Building Department\u2019s behalf which created the following change: MEP contractors are responsible for the design and certification of the system including the hiring of the third party inspectors (typically same as seismic design engineer).  In the Las Vegas Valley, Encore was the first property to have this code enforced and Aliante was second.\n\nCriteria:\n\nCheck structural plan for seismic zone, 90% of Las Vegas area is Zone \u2018C\u2019 and Hospitals are typically Zone \u2018D\u2019.  Per code MEP engineers need to designate the seismic Zone as \u2018D\u2019 until the Structural engineer designates the actual zone on his drawings (review that these are coordinated).   \nZone C requires only the duct and HVAC equipment associated with life safety systems to be braced.\nZone C requires bracing for all piping for hazardous products such as gas, medical gas, fuel etc. that is 2 \u00bd\u201d and larger; piping in boiler, mechanical equipment and refrigeration mechanical rooms that is 1 \u00bc\u201d or larger; Any piping that could sway into HVAC life safety duct or equipment.  See page 3.2, Seismic Restraint Manual by SMACNA.  To save money request design engineers keep gas piping smaller than 2 \u00bd\u201d when possible.\nSeismic restraint systems should be designed by a registered seismic or mechanical engineer.  Seismic Systems should be installed per these stamped approved drawings and a letter of compliance issued by the engineer after work is complete.\nRestraints shown on engineered drawings that are not installed should be brought to the attention of the design engineer to be excluded from being required.\nDetails of components required and attachment to structure should be provided by seismic engineer and can be found in SMACNA Seismic Restraint Manual.\nTypical restraints consist of  \u00bc\u201d cable attached to structure at approximately a 45 degree angle from duct or pipe to structure above.  See details in SMACNA Seismic Manual Chapter 4 and Chapter 7 for size requirements.  Restraints can also be angle iron attached to structural member horizontally, see SMACNA Seismic manual Chapter 7 for cable or angle requirements.  All above typical restraints should be shown on engineered plans, specific to project.\nTypical bracing should have minimum (2) transverse braces and one longitudinal brace per duct or pipe run.

Bracing installed 24\u201d from elbows transversely can be considered adequate for longitudinal bracing.\nWhen in Zone D systems need to be designed at inception with seismic bracing in mind. The design should incorporate one layer of MEP routing pressed up tight under deck with a single layer below, any additional layers of MEP would not be able to be constructed because of the amount of coordination around the seismic restraints.  Additional items would need to be routed on roof. \n \n\nExceptions for seismic bracing typically required for Zone \u2018C\u2019 are as follows:\n\n\u00b7 Hangers that are less than 12\u201d in length from attachment to structure to bottom of pipe or top of duct attachment (duct hanger must be attached within 2\u201d of top of duct with 2 each  #10 screws).\n\n\u00b7 Walls including gypsum board non bearing can be used as a transverse brace for duct or pipe which pass thru.\n\n\u00b7 Square duct that has a cross sectional area of less than 6 square feet, for example 35\u201dx24\u201d would be less than 3\u2019x2\u2019 or 6 square feet.\n\n\u00b7 Round duct less than 28\u201d does not require bracing.\n\n\u00b7 Fan coils, fans, small equipment weighing less than 75lbs and is connected to duct without flex connection.\n\n\u00b7 Roof duct less than 12\u201d above roof structure.\n\n\u00b7 Any system not part of life safety HVAC systems. \n\nThe above information is a brief overview of what should be reflected on the engineered seismic restraint documents for further information consult SMACNA Seismic Restraint Manual.

The owner did not want an access panel in the face of the tub deck and expected to be able to pull the tubs up and out of the tub deck to work on them.  As this had been done in Clark County, which was the direction we proceeded with.   Later, the city inspectors had concerns that if we did not install an access panel, we would not meet electrical code requirements for access, Our solution was to caulk in the stone pieces that were in front of the motor access instead of grouting them in.  This allowed the caulking to be cut and the stone removed to gain access to the motors.  As it turned out, two of our motors malfunctioned while we were under warranty and access had to be gained to them.

Health Department expressed some concern about this issue.\n\nInitial Observation\n\nWe found several floor sinks (56) showing heavy signs of rust at the bottom of the sink (see photos #1, #2, #3 and #4).Some sinks showed more wear than others and most of the sinks did not have the strainer inside of it. See photo.\n\nBackground\n\nBombard Mechanical were the installers and Josam Company were the suppliers of the floor sinks. Josam Floor Sinks Series #49340, 49360 and 49580 were installed. The Josam Floor Sink comes standard with a cast iron body, grate and aluminum dome strainer. All cast iron parts are coated with a high-gloss, baked acid-resistant powder coat epoxy. The thickness of this coating is 1.8-2.2 mils.\n\nInvestigation\n\nWhen investigating this issue we researched all possible causes that may have contributed to the failure of the finish.\n\n# 1- Type of cleaners used to clean the tile floor.\n\n# 2 \u2013 The type of cleaners used to clean the equipment.\n\n# 3 \u2013 What the cleaning staff uses to clean the sinks.\n\n# 4 \u2013 What type of chemicals and food stuff makes its way to the sink.\n\nWe also investigated other Station Casino properties to see what type of floor sinks were used and if they showed the same type of wear.\n\nIt was noted that at GVR (Quality Mechanical) and at Red Rock (Hansen Mechanical) the floor sinks showed very little signs of rust or wear to them (see photo #5). We also noticed the floor sinks had a thicker porcelain finish and all the strainers were in place.\n\nTwo floor sinks were removed to under go testing to find out what caused the finish to fail. One sink went to Josam Company and the other sink went to an independent company hired by PBG., Bombard has replaced all the floor sinks (see photos #6 and #7). The new sinks were supplied by Zurn LC series FD2375 (see photo #8) and comes with a porcelain finish not a powder coated finish. The test results have not come back yet, but we feel that the porcelain finish is the key to resolving this issue and we also believe that the strainer must be in place to help protect the finish. We did find a cleaner named Grease strip that is used to clean the equipment, on the back warning label it states, \u201cThis product will etch aluminum and should not be use on painted surfaces\u201d. This cleaner is also being tested to see if it is part of the reason the finish is failing.\n\nLesson Learned: \nDo not use Josam Floor Sinks on our projects (or floor sinks with out a porcelain finish), \tHave you ensured that the floor sinks have a porcelain finish, and not a power coated finish, to prevent rusting and deterioration that may be caused by cleaning chemicals?\n23 00 00 Heating, Ventilating, and Air Conditioning (HVAC), Procurement, nan, Typically, when dealing with control systems, pneumatic tubing or wiring is used to determine the duct static pressure and the building pressure.

The provided material specifications do not appear to match the product being utilized and do not comply with the requirements of Chapter 6 of the UMC. In summary, the flame spread rating must not be more than 25 and a smoke-developed rating of not more than 50., Most buildings are now utilizing electronic sensors; however, in this case, pneumatic tubing was used and the determination from the Clark County Building Department is that it is acceptable to use. The attached letters and documentation were used to prove that this product satisfies the requirements of 2000 UMC Section 602.2 and therefore may be installed exposed within ducts or plenums, \tHave you ensured that no pneumatic tubing is being installed within the open-air plenums above the ceilings?\n23 00 00 Heating, Ventilating, and Air Conditioning (HVAC), Buyout, nan, Our chillers were not pre-charged with the required refrigerant. After scheduling the chillers start-up, we were notified that due to shortages of this refrigerant nationally, our shipment was extended 3 weeks. We have tried to work with York to get this expedited but they are not able to meet our schedule, Fortunately, we can get the refrigerant from a local source that has immediate availability. Unfortunately, it will cost us approximately $2.00/lb for a handling fee, which equates to roughly $17,000. Once our scheduled refrigerant from York arrives, we would then turn it over to the local supplier, \tHave you considered during buyout to have the chillers be pre-charged with refrigerant at the factory instead of charging them on site to avoid any potential delays (consider the additional weight in shipping and the hazardous waste transportation)?\n23 00 00 Heating, Ventilating, and Air Conditioning (HVAC), Procurement, nan, Some Variable Air Volume (VAV) and Fan Coil (FC) units in the property did not have proper access because they were too high above the ceiling. In addition to this problem, the owner\u2019s representatives eliminated all catwalk systems in the property during the VE process., Always consider the access requirements needed for mechanical units above the ceilings and coordinate with time. To help with this process PBG took the lead in the coordination effort.  \n\nA spreadsheet was created to ensure that all the VAVs and FCs were looked at (see attachment #1). The spreadsheet lists all the units and compares their elevations with the ceiling elevation at that particular location. This helped the team determine the problem areas and find a solution.

In some scenarios the solution was to lower or raise the units a little. In other locations there was an obstruction so the units were adjusted horizontally to avoid the framing for a soffit or high wall. This we also moved a few units to get them closer to hard lid access panels. In areas specific to the restaurant row (example Italian Restaurant and Buffet), catwalk were added because the ceiling design conditions did not allow for access panels. This was due mostly to the high end finishes and design patterns. In these areas the catwalks served a double purpose because they also provided access to the grease ducts. In other areas where there were high end ceiling finishes (example Center Bar) and the units could not be relocated out side of that area the diffusers were changed from fixed diffusers to removable diffusers so they could be used as access panels. As we moved from area to area a solution that best fits each situation was used to provide proper access.\n\n            Like all other coordination efforts, it is best to start as early as possible. In some areas of Aliante Station Casino, rework could have been avoided if this was coordinated earlier. In other areas, the units could have been relocated outside of the venue that have high finish ceiling but the duct work and diffuser could have still been located in the venue itself. Keep the catwalks systems if needed and push for your mechanical and framing subcontractor to take lead in this coordination effort., \tHave you proactively coordinated proper access requirements for all mechanical components above the ceilings throughout the property?\n23 00 00 Heating, Ventilating, and Air Conditioning (HVAC), Procurement, nan, Aliante Station included two front of house wine rooms in its higher end restaurants and we encountered some mechanical issues during the startup stage of construction.  The problems were actually caused by the late addition of the wine rooms, post design phase, but didn\u2019t surface until we tried to startup the system.\n\nTraditional wine cooler design would provide a local air conditioning unit, similar to what are utilized in computer equipment rooms.  These types of units are used because they have the ability to control humidity.  Liebert is a common manufacturer.   The problem with this method is these units are large in size so they usually require their own equipment room.  Second, these units produce cool air through a refrigerant system.  However they require condenser water, which is 75 to 90 degrees, to cool the refrigerant compressors.  We not only didn\u2019t have a space to house large units but Aliante\u2019s mechanical systems used chilled water, which is 42 to 52 degrees, Ideas:\nAchieving higher temperature water was not easily solved.  We could have used domestic cold water as it gave us the required temperature but our plumbing design didn\u2019t have a cold water return system.  Any water used in the units would be continually run down the drain. \n\nA second option was to incorporate a thermostatic mixing valve and independent pump into the system in order to create a secondary water loop at a higher temperature range.  This idea did not come without its own problems.  The units have their own internal thermostatic valve that operates by reading the refrigerant compressor pressure.  When required pressure is achieved the valve closes.  The closed valve gives the independent pump nowhere to pump to; this in turn causes it to overheat/overload.

Because the independent pump is not operational when the valve opens requiring water, it doesn't get any so it trips the building emergency management system alarms for non working equipment.  If you remove the units internal valves there is too much flow to the unit and the refrigerant compressor freezes. \n\nThe pump issue could be solved in one of two ways:\n\n1.      Install multiple units on one pump, this way there is always a unit requiring flow and the pumps flow of water is not stopped.\n\n2.      Give each unit its own loop as originally planned and remove its internal thermostatic valve, but regulate and slow the flow with a multispeed pump.\n\nSolutions:\nWe solved the sized issue by using multiple units and hanging them in an adjacent back of house plenum space.\n\nWe used the second option listed above to achieve the required water temperature range.\n\nLesson learned:\nWine coolers are a sensitive install.  It took considerable time to diagnose and solve this problem.  The additional time need would have been a bigger issue had we not had time at the back end of the schedule.  In our scenario procurement of the proper equipment would have given us plenty of time to dial in the start up and controlled temperature.  For future projects the sooner these units are planned for during the design phase the better they can be accommodated. \n\nAdditional Equipment Note:\n\nLiebert now makes a fan coil unit with DX refrigerant backup.  It runs just like a standard FCU at 42 degree chilled water.  If the buildings chilled water system fail, the units flow can still be maintained on emergency power.  If the system is not producing new chilled water the loop temperature will gradually rise.  The unit senses this rise and when it hits approximately 65 degree water, the unit trips into the DX mode and continues running.  When the buildings chilled water system is repaired the unit reverts back to the FCU mode, \tHave localized air conditioning units required for wine rooms been planned to ensure that the suitable equipment is procured and properly installed?\n26 00 00 Electrical, Procurement, nan, At WMC III we installed (2) line ups of 12,470V switch gear to serve as the primary power distribution for the building and parking garage.  Per NPCo plans each line up of gear needed to have a contractor installed precast RS-82 pull box underneath the meter section of the switchgear to make the final terminations.  The boxes were orientated/installed per the approved NPCo plans and matched the (E) primary power distribution for the previous buildings.  The NPCo inspector said that the boxes were orientated improperly per their standards and didn\u2019t care what the plans showed or what was done previously and he wasn\u2019t going to sign off on the underground until the boxes were rotated 90 degrees.  There were several meetings with NPCo to get this issue resolved so that no rework was needed.  They agreed after a few meetings to install them with the configuration in the field because that is the way it was shown on their plans and their own designers didn\u2019t follow their standards.

There were additional requirements for these generators because they were inside the building, F/S dampers were required to open to provide combustion air for the generators.  F/S dampers were needed because the generator room was required to be rated.  The dampers were tied into the generator via control wire so when it started up they would open and when it shut down they closed.\n\nInsulation on the large exhaust muffler was required to reduce heat gain in the room, \tHave you verified if the emergency generators will require dampers if they will be installed inside an enclosed rated space?\n26 00 00 Electrical, Procurement, nan, Artic Room-The Artic Room is a room where a guest can indulge themselves with a cold experience, where the floors are heated and there is an ice bowl which is filled with ice for a cold body rub down and snow falls from the ceiling.\n\nComplaint\nCustomers are complaining about being shocked when opening door from inside the Artic Room.\n\nBackground\nDesigns for Leisure were the Design Builder of the Artic Room and Carbonic was the suppliers and installers on the heat mat.\n\nInvestigation\nThe request for an investigation came after six written complaints about being shocked were submitted to Caesars Palace.\n\nWhen the Artic Room was tested using a voltage meter a reading of 12-60 volts was taken directly from the floor.  We placed one lead from the voltmeter on the door handle and the other lead was placed on the tile floor this would give us a voltage reading. Upon further investigation it was found that voltage was only present where water laid. The dry areas would show a negative reading on the voltmeter.\n\nAll electrical connections where checked through-out the Artic Room no problems were found.\n\nThe Carbonic Heat Mat was found to be the problem (see photos # 1 and # 2). When investigating the heat mat it was found that this mat can not be use in a wet environment. When Designs for Leisure was asked why they installed this heating mat in a wet room their response was that this room was never intended to be a wet room. If this was the case why did they waterproof the floor and install a drain in the middle of the room? The heat mat was installed to help melt the snow and ice, so it would not build-up on the floor and bench. When melting occurs you get water. Designs for Leisure were not very cooperative through-out this investigation and Carbonic the supplier of the heat mat went out of business., All Carbonic Heat Mats were replaced through-out the Spa.

All emergency electrical rooms must be 2 hr rated, have panic hardware on the doors, and the door to the emergency electrical room must swing out.\n\nDoors and frames can obviously be either non-rated or rated. If the doors and frames are non-rated but have rated labels on them, the CCBD will require these to be taken off. If the doors and frames are rated, they must be labeled with appropriate rating on both the door and frame.\n\nPROBLEM\nThe architect never showed 1 hr and 2 hr ratings on electrical rooms and emergency electrical rooms, respectively. The CCBD will not allow this and requires the above stated. Labels were not part of the specification and were not required., Although the architect never showed these ratings, we were able to escape the perils of the CCBD by installing the proper rating on these rooms and also having installed the labels on the doors and frames. This is a good lesson to learn when bidding out a project for both the drywall and door subcontractors, \tHave you verified during buyout that the doors and frames located in electrical rooms and emergency electrical rooms are rated doors (1-hour and 2-hour respectively)?

There are two options; move all of the utilities (sewer, gas, water, etc.) or the CCBD has allowed us use a NEMA 3R Can (approximate cost is $200). This is an exterior weather tight can on the interior. The better solution is to use the NEMA 3R can and avoid having to install drip pans or relocating the utilities. However, this is only acceptable if you have a head clearance of 7\u2019 or 8\u2019.\n\nAlso, any emergency feeder (power) running through and electrical room or IDF room must be protected using a sprinkler system above it.   \n\nPROBLEM\nWe installed an electrical panel with foreign objects over head and did not have protection over the emergency feeders, We were able to eliminate the need to relocate the utilities by installing a NEMA 3R Can. This helped tremendously on schedule and cost of the job and is the better option.

See below for cross-section of bar and lights specified by the designer, This is an item that will never get coordinated between the architect, lighting designer and soda/liquor/beer vendor.\n\nOnce dimensioned shop drawings have been received along with lighting specifications you can determine available clearances beneath the bar.  In this case the lights were 5\u201d deep and were pushed to the back of the under counter surface.  In addition to the lights there are several items that will not be shown on drawings but will need to be accounted for when determining the bar layout.  The items include:  beer tower with supply hose, scupper drain line and soda and liquor guns.  Typically these items are owner supplied and can be hard to gather information on.  As you can see from the sketch below, the beer tower and soda/liquor guns both overlapped with the under counter light.       \n\nSolution:\nThe lights were re-ordered in a different kind of fixture that has a greater thickness but is only 2-3/8\u201d in depth.  This provided adequate clearance for both installation and maintenance of the fixture around the adjacent beer and liquor equipment., \tHave you coordinated the electrical drawing clearances of lights beneath the bar with other bar equipment (beer tower with supply hose, scupper drain line and soda and liquor guns, etc.) to avoid any interferences?\n28 46 00 Fire Detection and Alarm, Procurement, nan, Smoke detector locations do not match location on drawings.\n\nBackground\nBombard Electric was the installer of all the smoke detectors and Simplex installed the fire alarm panel. The type of senor that was installed is Zero velocity sensor which are more sensitive then regular duct detectors.\n\nWhen a smoke alarm is activated the fire alarm panel will display the identification address of the smoke detector activated. On the wall next to the fire alarm panel is a set of drawing showing the location of all the smoke detectors. The Engineering dept. and Security Dept. have Three minutes to locate and physically identify the smoke detector that was activated before the Fire Dept. responds to the alarm.  \n\nInvestigation\nWhen investigating this issue it was found that the drawing that show the locations of all the smoke detectors did not show the correct locations. Simplex was called out to investigate their addresses on the fire alarm panel. Simplex could not find anything wrong with the panel. To illustrate the problem Wally Jensen manually activated a smoke alarm, the panel displayed the identification number Simplex found the location on the drawings which was the back of kitchen in the buffet. We then went to the location and found no activated alarm at this point the engineering and security staff is now in a race against time to find the activated detector. Wally then showed Simplex were the smoke alarm was, it was down the hall about 100 feet away from were the drawing showed it was, The resolution of this issue was found to be in the drawings. The drawing that were handed over to Santa Fe were the original drawings and not the as built.

PBG asked the designers to provide location and general requirements for all the components but the design team would not provide that information., Ask for a complete design of this room early in the project. In most occasions the design team will avoid at all cost to create a complete design on this room. If they do not provide this then do the following:\n\nRead the FCC requirements found in your Life Safety Report (see attachment #1).\nCreate a list of all the components in that room. Include electrical, low voltage, fire suppression, conveying systems, millwork, and furniture as you will need to coordinate all of these.\nObtain cut sheets from the subcontractors, designers, and owner for all the components needed.\nObtain an accurate floor plan of the FCC room with dimensions.\nUsing the floor plan and the equipment specifications assign locations to all the components and create a sketch. Be sure to go on a field walk and coordinate with the superintendent for this area. Check wall types and check if any troughs are needed. \nSend the complete sketch for your life safety consultant, and subcontractors for their review and input. Make corrections as necessary.\nSend a final sketch to the design team and owner for their review (see attachment #2).\nHave the architect approve the drawing and issue electronic drawings for formal distribution and construction (see attachment #3).\nA separate procurement list for this room and constant field walks are highly recommended, \tIs the design for the Fire Command Center complete?  If not, can the requirements be found in the Life Safety Report?  What are the components necessary for it (include electrical, low voltage, fire suppression, conveying systems, millwork, and furniture)?  Can you obtain cut sheets from the subcontractors, designers, and owner for all the components needed?  Is there a floor plan with dimensions for the FCC available?  Can it be used to generate a sketch of the FCC and assign locations to all the components (check wall types and check if any troughs are needed)?   Have you sent the complete sketch to the life safety consultant and subcontractors for their review and input?  Is the Architect able to review, approve and distribute the final sketch?\n28 46 00 Fire Detection and Alarm, Permits and Inspections, nan, The 2006 International Fire Code, section 611 states that any building not meeting the criteria set forth within this code section regarding radio coverage shall provide an approved two way fire communication repeater system.  When this code was adopted by the North Las Vegas Fire Department it was expanded to include all emergency services.  The purpose of this radio amplification system is to provide reliable radio communication for emergency service responders.  We are currently looking into what other area jurisdictions have adopted this along with any specific amendments., System Design:\nThe system is required to be in a 2 hour rated enclosure so running conduit underground to its final termination point eliminates the added work of rating overhead conduit runs. \n\nWhen the conduit comes up from underground you will need to provide a rated system such as the attached 3M product used in this situation.

Since all runs must be completely enclosed in wrap they become very bulky and hard to fit into wall cavities and tight runs.\n\nElectrical boxes should be specified as NEMA 4 and need to be oversized to allow for the equipment heat to dissipate within the box.  Since the boxes are oversized, make sure the owner/architect clearly defines box locations and allows enough room for these cabinets.\n\nThe system is designed to support two frequencies:  700 & 800 MHz.  The fire department uses an 800 MHz frequency while the police department currently uses a 700 MHz frequency.

This needs to include all elements of installation such as type of conduit, fiber, cabinet specifications, etc.  See attached for what was used in this scenario.\n\nConstruction:\n\u00b7 If the system designer is also going to install, check that they are licensed to do work in this area.  In our scenario the system was designed by McIntosh Communications.  However because they are not a licensed contractor pulling the permit and installation were preformed by our electrical subcontractor (Bombard).\n\n\u00b7 The selected subcontractor may need specialized training from the supplier to install the equipment.  In our situation Bombard had not previously installed this type of system so a McIntosh representative was present during installation for guidance.\n\n\u00b7 As part of the system, the owner is required to provide the fire department with portable radios in fire command.  Criteria for the radios are set forth in the attached guidelines.\n\n\u00b7 The emergency services radio frequencies require an FCC license.  The license is obtained by the property owner and must be submitted well in advance of final testing.\n\n\u00b7 During final inspection by the fire department, the owner needs to supply a maintenance contract with an authorized maintenance company.\n\n\u00b7 Check specifications to see if it specifically calls out for rigid conduit.  If it does make sure subs do not run EMT unless an Engineering Judgment is received and approved., \tHave you ensured that the permit application for the first response emergency system (radio repeater) includes all the elements necessary for the installation, including the type of conduit, fiber, and cabinet?
