GOV'T ANSWER

2 1 6-Aug-25 RFI's 57 & 189 describe what is required in the Mission Planning Room and the Offices. It does not address the comm requirements of the Auditorium. The audience typically doesn’t need comm workstations under their seats. Can the 30qty comm workstations under the audience seats be removed and if not removed, what networks are required in the auditorium?

SHEET LV-201 COMM 30 qty workstations to remain, assume SIPR network; TCR to confirm in 65%

2 2 6-Aug-25 RFI 66 response states that all communications equipment including Patch Panels, switches, racks, and etc.

are to be USAF IT provided. Typically only switches and patchcords are USAF IT provided. Will contractor be required to provide and install all racks and patch panels required for the NIPR/SIPR/JWICS/SAP/and SIM Networks?

RFI #66 & #193 Response COMM RFI Log 1, #66 & #193 Response Revision; USAF IT shall provide the switches and patchboards as typical and all other components shall be provided by the contractor.

2 3 6-Aug-25 If Networks are not allowed to share single workstation outlet boxes there will be 5qty workstation outlet boxes at every location, one each for NIPR, SIPR, JWICS, SAP, and 2x SIM Networks. Can any of these networks be combined at the workstation outlet box to minimize the workstation footprint?

RFI #57, #189, & #191 Response COMM Combining workstation outlets must be approved by the TCR during the 65% design review.

2 4 6-Aug-25 There are 30qty floor box Quad receptacles shown under the audience seats of the auditorium. This seems excessive for an audience and would be a cost savings to remove or reduce them. Can the floor box Quad receptacles be reduced or removed from under the audience seats in the Auditorium?

Sheet E-301 ELECTRICAL See RFI Log 2, #1 above.

2 5 6-Aug-25 The responses to these RFI's contradict each other. Will lighting be required for the North, Devlin Drive, Parking lot?

2 21 7-Aug-25 RFI 70 regarding sustainability: GOV is asking DB Team to write a Div 1 spec section. Usually GOV edits and provides Div 1 sections for DB RFPs. The concern is that if all proposers edit their own version of this spec section, there will not be a common basis for bidding.

Response to RFI 70 with response provided in Amd. 03. Attachment 4, Appendix D, 35% Specs TOC

SUSTAINABLE DESIGN RFI Log 1, #70 Response remains unchanged. Current SOW shall be included as the basis of the Div 1 Specs.

FA485125B0001 2 OF 12

2 24 7-Aug-25 Please resolve the conflict between the responses to RFIs #37, #74 and # 75 answered with Amd. 03: All questions pertained to SOW 1.3.16.4 and 1.3.16.5, and wanted to confirm whether only the boundary walls of the secure spaces are required to have 50 STC rating (i.e., ICD 705 Wall A, Sound Group 4), or if the non-secure boundary walls of the Mission Planning Rooms are also required to have 50 STC rating, as SOW

1.3.16.5 calls for 50 STC Doors to these rooms, but does not specify 50 STC rated walls.

RFI # 37 response says the only 50 STC walls are the boundary walls.

RFI #74 and #75 responses indicate that both the perimeter walls for the classified area (74) and the partitions for the various offices, MPRs and Briefing Rooms inside the classified area and references ICD 705 Wall A, Sound Group.

Please provide clarification as follows: Identify each room (by Room Number) which requires 50 STC rated partitions/walls (all 4 walls) as well as 50 STC rated door, with the understanding that only the rooms walls which are also part of a secure boundary wall will be constructed to comply with ICD 705, Wall A, Sound Group 4. 50 STC partitions which are not part of a secure boundary do not need to meet other ICD criteria for boundary wall construction (e.g. gauge and stud spacing).

Am 3, RFI Responses for #37, #74 & #75, and SOW 1.3.16.4 and 1.3.16.5

ARCHITECTURAL RFI Log 1, #37 and 74 Response remain unchanged, in addition see above response to RFI Log , #22 and 23 RFI Log 1, #75 Response Revision: New partition walls for the various offices, MPRs, and Briefing Rooms are not required to be STC 50, Wall A, Sound Group 4.

2 25 7-Aug-25 Can an air-cooled chiller with a capacity greater than 40 tons be used on this project? SOW 1.4.42, Attachment 4, Appendix J Nellis-Creech Mechanical and Plumbing Requirements, Item 9f.

MECHANICAL Yes, The government requires all chillers to be air-cooled and water-cooled chillers are not allowed under Clark county regulations.

2 26 7-Aug-25 If a 4-pipe fan coil system is used in the HVAC building design, please confirm that the Server Rooms and Utility Room only need to be served by ductless DX split systems.

SOW 1.3.20.15, 1.3.20.16, and 1.4.42.29.3

MECHANICAL In the Server rooms ductless dx split system are to be redundant systems specific to these room requirements. In the Utility room a ductless dx split system can be used.

2 27 7-Aug-25 Based on the SOW 1.3.1.6.6 and RFI Response 151, this project is required to comply with the 21 minimum ATFP standards given in UFC 4-010-01 dated 12 December 2018 with Change 3, 24 May 2024. Standard 2 requires a zone of unobstructed space to extend 33ft from the outside edge of the existing building and additions. The intent of this space is to prohibit an aggressor from concealing packages or other items which might constitute a threat.

The existing CMU wall to the northwest of Existing Building 47 creates an enclosed area that is only accessible via a lockable gate to the adjacent sidewalk or from Building 47. There is a new break room in Building 47 and a shade area in the enclosed area, which will encourage foot traffic into the enclosed area.

Please confirm this area can be considered a space in which threats would be visually detected by building occupants per Section 3-3 of UFC 4-010-01, and that a lid spanning from the CMU walls to the project buildings would not be required as a physical barrier to keep threats from being tossed from beyond the CMU walls. Please confirm is it acceptable to only enclose site elements within the 33ft unobstructed space that provide opportunity for threat concealment, and no additional enclosures are required.

SOW 1.3.1.6.6 and RFI 151 Response. ATFP See RFI Log 2, #13 above.

2 28 7-Aug-25 Per the response to RFI 41, "New CMU site walls shall match the existing split-faced, honed and vented CMU as applicable. EIFS is not to be used on the new CMU walls. Per SOW 1.4.7.2 Existing exterior masonry walls shall be painted to match the new exterior masonry walls." On Sheet A-201, Key Note1 and Exterior Finish Schedule Note E-1 on the West Elevation identifies this wall as new (CMU) and says to paint to match existing. Please confirm whether the new exterior CMU walls building walls are required to be painted, or have exposed integral color as described in the RFI response cited above.

Response to RFI 41, SOW 1.4.7.2 and 35% Drawing A-201

ARCHITECTURAL The complete building shall be painted/repainted a matching color. Please are demolished for openings and require repair, the EIFS shall be repaired as required.. The larger new addition on on the west shall not receive EIFS.

Contractor may propose EIFS on the smaller new addition in the south

(RFI Log 1, #41 Clarification)

2 29 7-Aug-25 The SOW and 35% Concept Drawings specify the provision of 6" H raised access flooring to be provided for the Auditorium and Large Multi-Purpose Room; the access floor appears to be required to accommodate cabling and receptacles for power and data for Auditorium seating and Multi-Purpose Room cubicles.

On recent projects designed for ICD 705 compliance, access flooring has been eliminated from the design by security; it creates a vulnerability as another concealed space requiring regular inspection. Data has been routed to workstations via cable trays exposed below the ceiling to surface-mounted raceway at walls or to power poles, and at floors using an inspectable system like Connect Rac. Please respond to the following questions:

1. Confirm that the use of the proposed raised access flooring system has been vetted by the AO/SSM or other accrediting authority.

2. Confirm whether the raised access flooring can be deleted at the Auditorium, or must be provided as shown, as a surface-mounted distribution system will be too disruptive for the seating configuration.

3. Confirm whether the raised access flooring can be deleted at the large Multi-Purpose Room, as the power and data cabling can readily be routed to banks of cubicles from adjacent walls.

SOW 1.3.6.11, and Attachment 4, Appendix A 35% Concept Drawings A-201 and E-301

ARCHITECTURAL/TELECO

M/ ELECTRICAL

1. Final review of the design by the AO/SSM or other accrediting authority shall be completed with the 65% design

2. Raised access flooring at the Auditorium, shall not be deleted

3. Raised access flooring at the large Multi-Purpose Room shall not be deleted

The 35% design provided is a conceptual design. Contractor shall develop the 65%, 95% and 100% to maintain the same number of auditorium seats, workstations in the multi purpose room and square footage for the multi purpose room. Changes to the existing design shall meet all accessibility requirements, ICD 705 standards. If the design is modified for increased access under the floor contractor’s may propose a depressed slab, to minimize design changes due to the limited space inside the building addition for longer ramps to accommodate a 12” or 18” access floor at the interior and exterior. The cage requirements under the access flooring may be waived if space restrictions will only accommodate conduit installation.

Design coordination of this change with all disciplines shall be accounted for where the contractor proposes this change.

FA485125B0001 3 OF 12

2 30 7-Aug-25 Please reconsider the response to Amd 03 RFI 108 and height of access floor. Raising the height of the access floor to accommodate all of the below-floor utilities does not appear to be feasible, considering the additional space that would be required for a longer ramp while maintaining the same SF and quantity of seating. If additional clearance is required, it appears that a depressed slab may be needed to accommodate an access flooring system with adequate clearance. Please provide a specific direction for this issue, to ensure all bidders are estimating the same scope.

Response to Amd. 03, Comment 108 ARCHITECTURAL The 35% design provided is a conceptual design. Contractor shall develop the 65%, 95% and 100% to maintain the same number of auditorium seats, workstations in the multi purpose room and square footage for the multi purpose room. Changes to the existing design shall meet all accessibility requirements, ICD 705 standards. To minimize design changes due to the limited space inside the building addition for longer ramps to accommodate a 12” or 18” access floor at the i-terior and exterior, contractors may propose a depressed slab. The cage requirements under the access flooring may be waived if space restrictions will only accommodate conduit installation. Design coordination of this change with all disciplines shall be accounted for where the contractor proposes this change.

2 31 7-Aug-25 The referenced SOW section (and many others) describes STC criteria for the construction of the secure boundary of the ICD 705 spaces and references the Technical Specifications for Construction and Management of Sensitive Compartmented Information Facilities, Version 1.5.1 (ICD 705) in Appendix P.

Please clarify the acoustic testing requirements for the (2) secure building areas.

1. Will the acoustic testing be performed by the Government or will the work be included in the Contractor's scope?

2. If the testing is to be performed by the Contractor, may testing be performed by the D/B acoustic design consultant, or will an independent 3rd party testing agency be required?

3. Please confirm whether the instrumented acoustical testing may be performed per ICD 705, Chapter 9 Acoustic Protection, C. Acoustic Testing, 2.g) to Noise Isolation Class (NIC) Standards, with results to comply with NIC 40 for Sound Group 3 and NIC 45 for Sound Group 4 or whether the acoustic field testing is required to meet or exceed the STC (lab) value cited (i.e. 50 STC-rated wall shall achieve minimum 50 STC in field, not

NIC 45).

SOW 1.3.1.4 and Attachment 4, Appendix P

1. Acoustic testing shall be included in the Contractor's scope

2. An independent 3rd party testing agency would be required

3. Instrumented acoustical testing performed per ICD 705, Chapter 9 Acoustic Protection, C. Acoustic Testing, 2.g is a noted alternative but must be approved by the TCR in 65% design.

2 33 7-Aug-25 The Response to RFI 62 indicates: “a. New fiber will be installed from B47 to P6 through existing manhole duct system” – where is P6? How many fibers and type of FO cable?

Amd. 3, Response to RFI 62 COMM See RFI 2-33_P6 (Bldg 6) Location.png

B47 has 3 single mode fiber optic (SMFO) cables and 1 copper cable

99 CS does not see a reason for any more than that in Bldg 47, but Contractor is to confirm the existing fiber is adequate during design.

2 34 7-Aug-25 The Response to RFI 104 refers to MH 287A – please provide a plan which identifies the location of MH 287A?

Amd. 3, Response to RFI 104 COMM See P6, B47 and MH 287A locations.pdf

2 35 7-Aug-25 We noted that there are several missing Key Notes on the 35% Concept Drawings; please provide the missing notes for Drawings listed below:

2 36 7-Aug-25 The original building is a Type V construction with steel roof joists and wood stud interior partitions. If the new additions and the existing building are to be considered as a non-separated occupancy, the construction type would also be Type V. Should the construction type be changed from II-B to V? If so, would wood construction in the additions be acceptable?

GI002 35% Drawings Life Safety No, new wood construction is not permitted.

2 37 7-Aug-25 SOW states under "FLOORS" that "Colors and textures of each item must be selected by the government".

Will the government be providing standard finishes for all interior finishes to be used, or is this limited to flooring only? Will the design team need to provide any finish schemes for government approval?

SOW 1.4.13 INTERIORS Contractor is to propose the finishes for all interior finishes to be used and the government will approve the selections. The design team must provide color schemes for government review and approval. See SOW 1.8.2.5, 1.8.2.6

2 38 7-Aug-25 SOW states under "Interior Design Scheme" to "Provide a complete room finish and color schedule in the construction documents. Schedule shall be coordinated with the color board." Will color scheme be provided by government or is to be developed by design team?

SOW 1.8.2.5. INTERIORS Color scheme is to be developed by design team and submitted to the government for review and approval.

2 39 7-Aug-25 SOW references required "Color Boards". Confirm quantity of binders to be submitted to Government. SOW 1.8.2.6. INTERIORS Samples shall be installed on an 8-1/2"x11" foam core board.

2 44 7-Aug-25 Under the requirements for SEALED BID PACKAGE INSTRUCTIONS.

It calls for the requirement of providing a CD with bid items 1-7 burned onto the CD.

Subcontractors and Vendors submit their prices at the last minute. Trying to burn the CD with all 7 documents at the last minute will be problematic.

Items 1,2 and 4-7 can be burned onto the CD without any issue prior to bid day.

Would the government consider accepting items 1,2 and 4-7 burned onto the CD and item 3, the bid schedule, submitted handwritten on the provided bid schedule?

RFP - SEALED BID PACKAGE

INSTRUCTIONS

CONTRACTING The requirement for items 1-7 on CD remains.

2 45 7-Aug-25 It is our understanding that the reason the government is requesting the General Contractors to provide a CD with the Sealed Bid Packages, is to save the government the time of scanning Each General contractors bid packages into their system.

Would the government consider using an electronic submitting system such as PIEE or a DOD safe file rather than the CD?

Burning a CD on bid day will be very problematic.

With Vendors and subcontractors submitting their pricing closer to the bid submission time, burning the CD at the last minute could delay the process and eliminate some General contractors.

RFP - SEALED BID PACKAGE

INSTRUCTIONS

CONTRACTING There is no indication systems such as PIEE or DOD SAFE will be functional at the time bids are due. Contractors must conform to the CD requirement in accordance with Section L.

2 46 7-Aug-25 Per 1.3.10.2, 1.3.20.3 and 1.3.20.15 dedicated split systems with redundancy are required for the two comm rooms in B47. Based on the 35% HVAC drawings, 2 sets of heat pumps ( at 3 tons each) are being provided for each server room to meet these requirements. Based upon previous experience, three tons of cooling may not provide enough to accommodate the number of racks shown in the 35% drawings.

See below for our recommendation:

Due to the project being bid based upon low cost (without technical capability consideration), please confirm if the bid should be based upon the 35% drawings or the tonnage listed in the recommendations above.

If the bids are ultimately based upon the 35% drawings and the Contractor’s design calculations show that additional tonnage is required, please confirm there will be a cost adjustment opportunity at the conclusion of the first design deliverable?

SOW 1.3.10.2, 1.3.20.3, 1.3.20.15 MECH Contractor shall address the project based on the tonnage provided and is open to modifications if further design and calculations prove to require additional tonnage.

2 47 7-Aug-25 The 35% drawings do not show independent heating/cooling systems for either the Utility Room #28 or Fire Riser Room #28A, but the SOW states HVAC should be provided. It is our understanding that both the Utility Room and Fire Riser Room will require independent zone control. A potential solution would be to utilize ductless split systems (with condensing units mounted on pads in yard).

Please confirm if the contractor’s bid should include split systems to provide independent HVAC control in each room?

SOW 1.3.20.5 MECH Yes, split systems to provide independent HVAC control in each room can be proposed.

2 48 7-Aug-25 1.3.20.5 states to provide ventilation systems for the entire facility, including restrooms. The 35% drawings only states to reconnect new exhaust grilles to existing exhaust fans on roof. Also, existing exhaust fans are shown to remain for the new restrooms and janitor closet, but no new exhaust grille is shown for janitor closet.

Should the contractor bid for the replacement of existing exhaust systems including grilles, exhaust fan and ductwork, or bid as shown on 35% drawings?

SOW 1.3.20.5 MECH Contractor shall bid to replace the existing exhaust system to include grilles, exhaust fans and duct work per the SOW.

2 49 7-Aug-25 Due to several issues, it is likely that the life cycle cost analysis will show the proposed 35% design concept is NOT the most cost-effective option from an efficiency and constructability perspective.

To help solve these issues, it is our opinion that a 4-pipe HVAC system (with an air-cooled chiller and boiler) will be the best way to meet the building criteria and provide the best overall product to the Air Force.

However, this system will be more expensive from a first cost standpoint and is not able to be bid on with this solicitation format. Please provide clarification on how the contractor should bid on the Mechanical systems.

If contractors are directed to bid the project per the 35% design concept and the life cycle cost analysis shows a different system is required, please confirm that cost modifications will be available after the first design submission.

See list of issues below:

a. Per Appendix Y, the mechanical calculations included in the solicitation show the total cooling load for the building (excluding the two server rooms) to be 36.5 tons. However, the cooling load calculations appear to have been calculated at 106°F outdoor conditions, and not the 117°F requirement listed in the SOW. The total design cooling load for the building will be higher once it is calculated at 117°F, and most likely above 40 tons. Air-cooled packaged equipment is typically derated by 25% when operating in outdoor conditions of 115°, so the total delivered cooling will only be 30 tons for the designed units. Therefore, the 35% design concept will not work.

b. In addition, the new rooms in the building will be densely occupied and require a substantial amount of ventilation. This is not addressed in the 35% design drawing package, as equipment performance criteria for the listed "high performance" 20-ton HVAC units are not given.

Appendix A (pg.40), Appendix Y (pg.32- 83), and SOW 1.4.42.22

MECH The government acknowledges the defect in the provided 35% design and refers back to the SOW where the contractor shall design and provide a HVAC system to meet the facilities cooling requirement. During the design build process, the contractor shall design to 117 deg F per the Nellis IFS.

During the LCCA, the contractor may choose another system as long as it follows all applicable codes and standards.

2 49 c. The 35% design drawings state to route the supply and return ductwork to the roof of the building and then back down through the roof inside each HVAC zone. This will result in a large number of roof penetrations and still will be extremely difficult to fit ductwork and VAV boxes above the ceilings. It is unlikely that ceiling heights higher than 7’-6” will be achievable in most areas.

Contractor is to confirm the achievable heights in their 65% design. Ceiling heights must meet minimum allowable ceiling height per code.

2 50 7-Aug-25 The 35% drawings do not reference demand control ventilation methods. Due to high occupancy, this building would benefit from this design strategy. Please confirm if contractor shall bid demand control ventilation per ASHRAE 90.1?

Appendix A (pg.40) MECH Contractor shall follow all applicable codes, standards, and SOW.

2 51 7-Aug-25 Plumbing plans do not show any water/sewer requirements in the Fire Riser Room. It is typical to have a floor drain and a 4" sewer connection to a hub drain assembly for testing. Should this be provided?

Appendix A (pg.45) PLUMBING The 35% design provided is a conceptual design. Contractor shall update the design to meet code and IFS requirements. Contractor shall provide floor drain and a 4" sewer connection to a hub drain assembly for testing as required.

2 52 7-Aug-25 S200 Foundation Plan Notes 5.B “10mil moisture barrier” contradicts with the SOW 1.4.1.9.7 “15-mil ASTM E1745 Class A poly Sheeting”. Should 10 mil or 15 mil moisture barrier be provided?

S-200 and SOW 1.4.1.9.7 Structural 15 mil per Apx F and SOW.

2 53 7-Aug-25 Room DDS-1 shows an operable partition to be demolished. Is there an existing steel support beam/structure that needs to be demolished as well?

AD-101 Architectural/Structural Please see sheet S-201 in the 35% design drawings. Existing and new beams are indicated. Contractor is to confirm the structural calculations in their design.

2 54 7-Aug-25 Do not capture the slab on grad demo needed to install new plumbing fixtures and drains. Should we assume removal of the slab at these locations for the new fixtures and drains?

S-200 & PD102 Plumbing/Structural Contractor shall assume demo and removal of the slab where required to accommodate the new fixture and drain locations.

2 55 7-Aug-25 Geotechnical report requires the footing embedment depth to be 24". A-201 shows the finished grade 8" below the finished slab. S-301 requires at 1'-3" thick footing. To meet the 24" embedment requirement, the block stem wall will need to be 2 cmu courses below grade. If the finish grade elevation is reduced from 8" to 7" only 1 course of CMU will be needed below grade. Can the finished grade be reduced to 7" below slab?

Table 8 Geotechnical Report; A-201, S-

Structural/Architectural Foundation shall be designed IAW the results of the Geotechnical Report provided unless Contractor performs additional testing to validate their proposed design revisions.

2 56 7-Aug-25 Structural drawings were not provided for the retrofit that converted the CMU wall at Grid 3-D to Grid 3-J to steel framing. Will specifics about the steel framing at this wall line need to be determined though on-site measurements, or can additional information be provided?

S-200 and S-201 Structural All available as-builts have been provided. Contractor will need to field verify the specific steel framing requirements.

2 57 7-Aug-25 Request confirmation of the applicable Buy American Act. The interpretation of the applicable Buy American provision is FAR 52-225-9-Buy American-Construction Materials (Oct 2022), even though it is not included in the solicitation. Per FAR Part 25.401(a)(1), acquisitions set aside for small business are an exception to the applicability of FAR Part 25.4 Trade Agreements, therefore 52.225-11 Buy American-Construction Materials under Trade Agreements (Nov 2023) would not be applicable even though it is incorporated into the Contract.

It is also interpreted that FAR Clause 52.225-9 (Oct 2022) is read into the Contract via the Christian Doctrine, even though it is not expressly incorporated and as a result, 52.225-11 (Nov 2023) would not be applicable.

FAR Clauses Incorporated by Reference, pg 13 of 37 of the solicitation

Section H - Special Contract Requirements

FAR 52.225-9 is not applicable for contracts under $6,708,000. FAR 25.401(a)(1) exemption applies only to acquisition of trade agreements listed in FAR subpart 25.4.

2 58 7-Aug-25 E-101 Keynote 1 states that the transformer will be provided by the utility company, and the contractor is only responsible for providing the concrete pad. However, utility companies do not supply transformers at Nellis AFB. Should the contractor provide the transformer, or will it be government-furnished?

Appendix A (pg.50) ELECTRICAL Transformers will not be government furnished, but they must be submitted for government approval. The existing pad-mounted transformer will be demolished per SOW 1.3.13.4. See SOW 1.3.17 Electrical for the requirements of the new transformer that is to be provided by the contractor.

Additional clarification are provided in RFI Log 1.

2 59 7-Aug-25 If a transformer is to be provided does the government have a minimum impedance rating for the 500KVA transformer?

Appendix A (pg.50) ELECTRICAL See appendix H for requirements and RFI Log 1, #34 Response.

2 60 7-Aug-25 Are the primary feeders required to be 15KV MV105 Cu cable with 133% EPR insulation with 1/3 Cu concentric neutral with jacket? Or is Tape shields acceptable.

SOW 1.3.17.4 ELECTRICAL Tape Shields are not acceptable as they are not able to be grounded at both ends and cannot carry appreciable ground or neutral current. 1/3 concentric neutrals are able to be grounded at both ends and able to carry any grounding current up to its rating and/or any temp. fault current without damage while the upstream breaker takes the current offline.

It is base policy to ground the primary MV neutral at both ends as a safety measure.

2 61 7-Aug-25 Are the Main panel breakers required to be of the LSI type or are thermal magnetic breakers acceptable? Appendix A (pg.57) ELECTRICAL It is required that all breakers in the main service entrance panel be 100% rated including SPD and metering breakers. Use of 80% rated breakers is prohibited for all service entrance panels greater than 225A. Note that in many cases, LSI breakers are required to meet coordination requirements between main service entrance main breaker and the panel feeder breakers and between main service entrance panel feeder breakers and their downstream panels or major loads, usually the minimum ratio is 1.5 for proper coordination.

2 62 7-Aug-25 E-101 Keynotes 2 and 3 indicate that the fuse cutouts and feeders to and from the transformer are to be provided by the utility company. However, at Nellis AFB, the utility does not provide this equipment. Will these items be government-furnished, or is the contractor responsible for supplying them?

Appendix A (pg.50) ELECTRICAL See RFI Log 1, #30 Response

2 63 7-Aug-25 E-102 specifies dimmer switches for certain areas of the building; however, a dimmer switch is not shown in the auditorium. Would the government like a dimmer switch to be provided in the auditorium as well?

Appendix A (pg.51) ELECTRICAL See UFC 3-530-01 INTERIOR AND EXTERIORLIGHTING SYSTEMS, including design requirements of interior and exterior lighting systems and controls based on the Illuminating Engineering Society (IES) Lighting Library® and the Energy Policy Act of 2005.

Yes, provide dimmers in the Auditorium. See Section 3-5.2 Auditoriums of UFC 3-530-01 for the dimming requirements in the auditoriums.

2 64 7-Aug-25 E-301 illustrates the building's power plan. Is the contractor to assume each office receptacle is a workstation and has no more than 4 workstations per circuit ? Is the est. load of each workstation 300VA or more ?

Appendix A (pg.55) ELECTRICAL In most office areas, most receptacles are planned for workstations.

However, in every office, there must at least one or more general purpose receptacles such that every portion of an office must be reachable with vacuum sweeper with a 15ft cord from one of the GP receptacles.

Office areas must also have dedicated receptacles for floor mounted copiers and shredders as required by the user.

For standard workstations, a maximum of 4 receptacles per dedicated workstation circuit is required and that 300VA continuous load per duplex receptacle is also required in the load calculations. Workstation receptacle loads are considered to be dedicated appliance loads at 300VA each and do not follow the NEC general purpose receptacle rules.

For nonstandard workstations the continuous load is greater and the number of workstations per dedicated circuit is further restricted from 4 to 3 or 2.

2 65 7-Aug-25 Will outdoor disconnects require NEMA3R/12 or NEMA 3 rating or is NEMA 3R acceptable ? Appendix A (pg.55) ELECTRICAL See RFI Log 1, #83 Exterior panels shall be NEMA 3 or 3R/12 or 4.

2 66 7-Aug-25 Other than lighting controllers and dimmer switches, are there any other lighting room by room requirements?

Is a control panel needed be able to control each room in one location? Touch screen interface?
