SOLICITATION W50S6Y-24-B-0002 Repair Hanger B1001 (MTX) Set 04 Q&A

03 April 2024 Advantor’s design RFIs:

1. Where else can Advantor put Panel Enclosures besides Rooms 117A & 168 (Com Rooms)?

Otherwise, there will be a large amount of wiring that will need conveyance to these Rooms and the exis�ng conduit may not be of adequate size. (Example, each Card Reader is a 22/6 cable, each HSS is a 22/6 cable, ML and ES are 18/2) A-E Response: All Conduits for security shall be new. No exis�ng conduit shall be used. Conduit sizing shall be done per NEC. Wiring from each door must be done using combo cable as indicated in drawings T-205, T-206, and T-393. Per informa�on provided by Advantor, each Access control panel should support four doors. The General Contractor may suggest a varia�on once under contract, and A-E will evaluate. Bid as shown in drawings and specifica�on.

2. Is there a requirement for IVA (Immediate visual assessment) for the LOD protec�ng the aircra�? If so, the exis�ng CCTV does not provide the required needs, cameras will have to be added.

A-E Response: The Government Security Force to confirm if IVA is required for the LOD. Also, refer to the new camera loca�ons in sheets TY-101, TY-102, and TY-104. The design does not rely on any exis�ng cameras in the Hangar Bay.

3. Will Push Bars (Door ACS) be preinstalled and have a �e-in provided for Advantor to connect?

A-E Response: Contractor means and methods. Advantor to coordinate with the General Contractor.

4. Area A Door 113B just has an ES and no CR on the design, yet it has a symbol C that specifies a CR entry. Is there a CR on this door or is it just an Emergency Exit Door?

A-E Response: Door 113B is an Emergency Exit Door only. A revision for TY-101 will be provided in a forthcoming Amendment.

5. Is IDS required in any of the other offices or entry ways besides the Hangar Bay Area?

A-E Response: IDS only required in Hangar Area as shown in drawings.

General Ques�ons

6. Please reference drawing G-103 phasing plan. I believe there will be a big issue with this plan as far ac demo, and comple�on of phase 1 areas.

Phase #1 Which is on both ends of the building has new panelboards, busways, panel feeders, cable tray and systems in each of these. The problem is these feeders, and busway start out of room 148 which is in phase 3. Also, the cable trays and systems start out of the main It room.

There is no way to complete phase 1 without disturbing phases 2 and 3 so please explain how we are to demo, and finish phase #1, when everything starts from the beginning in phase 2 and

3. I’m sure this is also affec�ng other trades as well

A-E Response: The three phases need to be completed in order. When work in other phase areas of the building must occur in order to complete the phase currently being worked on, the Contractor shall coordinate access with the Government. Specifica�on 01 14 00, para. 1.2.b details the requirements for detailing the Contractors ini�al plan for construc�on phasing by submi�ng a Construc�on Phasing Plan which shall also detail areas where temporary work access will be necessary to account for the access concerns men�oned in the ques�on above.

The Government will review and approve the plan and coordinate Contractor access when needed as construc�on progresses. Proposed varia�ons to the phasing plan shown on Sheet G- 103 and will be considered by the Government during the pre-construc�on submital phase.

Note. Paragraph 1.2.b also men�ons areas not currently turned over to the contractor shall remain in opera�on. “In opera�on” includes power, HVAC, water/sanitary and telecommunica�ons services. Provide temporary services if the main building systems service must be isolated from the affected area. U�lity cutovers and temporary access to other phase areas shall be requested from the Government for approval NET 15 days prior (Ref. para.1.2.c and 1.3.5). Off-regular hours work for certain tasks may be scheduled with the Government.

Addi�onal provisions for working around occupied areas are in paragraph 1.3.4.

7. One other major ques�on regarding drawing E-007 riser. It calls for us to add one new conduit and wire from each new 1500 KVA transformer to each of the exis�ng main switchboards. Since these exis�ng switchboards are located approximately 30’ inside the building and I assume fed underground, how are we to maintain equal consistency with wires? Do the floors need to be dug up and equipment removed, or can this be ran underground up to the building and then overhead through the exis�ng building to the switchboards?

A-E Response: During demoli�on protect exis�ng transformer secondary cables. Megger test exis�ng cables prior to re-termina�ng at new transformers. Report results to engineer.

Reterminate exis�ng cables at new transformers and adjust circuit breaker trip se�ngs to 1550 amps. Drawings will be revised to reflect in a forthcoming Amendment.

8. P-110A shows a new High Pressure Nitrogen Gas Drop being installed. However there doesn’t seem to be anything within plans or specifica�ons addressing what type of piping required, fi�ngs or how this line will need to terminate within the wheel & Tire Shop. Please provide this informa�on required for pricing.

A-E Response: Nitrogen Pressure Drop is for �res per the FRD. Refer to updated Specifica�on 22 00 00 for piping and fi�ngs in forthcoming Amendment.

9. Per sec�on 1.3.5.4 of spec sec�on 09 67 23.15 and .16 it required the prep and coa�ng applica�on must be cer�fied to SSPC QP8. Only 7 or 8 companies in the na�on have this cer�fica�on and 2-3 only do steel work. We can provide cer�fica�ons from the manufacturer for installa�on and knowledge/prac�ces of proper prep of substrate. With this being said, will this cer�fica�on be required?

A-E Response: Refer to prior RFI response Set 03 Q#9 & 10

10. In hangar 101, 102 on the RCP the structure states to be EXP. On the finish schedule shows no work to be done, but on the finish legend EXP shall receive Dryfall paint. Please advise?

A-E Response: Refer to revised sheet I-601, Finish schedule in a forthcoming Amendment. Areas noted with EXP for Ceiling in the schedule shall receive EXP finish as called out in the Finish Legend.

11. Page A-132-A, the RCP, shows a one-hour sha� wall ceiling, buted up to the mezzanine 10” joists. This is at +/- 8’AFF. In the past, a system such as this required smoke/fire dampers and special sleeves on conduits and pipes. Ques�on--- Will the sha� wall be the finished ceiling?

What type of access will the other trades have?

A-E Response: Fire dampers, and fire rated pipe sleeves and conduits are to be provided for any penetra�ons through sha� wall ceiling system. Refer to MEP drawings for these condi�ons.

The underside of the sha� wall ceiling type B2 is intended to serve as the finished ceiling for rooms 103, 108, 111, 112, and 113a.

12. As shown on drawings E-010, E-011, E-012, E-013, are the 400 Hz 150A receptacles needing to be Class 1 Division 2?

13. Will there be a FOD walk each day throughout the dura�on of the project?

Gov Response: Refer to Sec 01000, Item 20, Cleanup/Disposal of debris & Fill of SF1442, the Contractor shall keep the site clean.

14. As shown on drawing E-005, the class1 division 2 will be in the area up to 18” above the floor and within 5’ around each plane, but will the areas outside these be unclassified or be specified as something else?

A-E Response: Refer to sheet E-005 and applicable codes and standards including but not limited to the UFC’s and NEC. Sheet E-005 tags adjacent spaces with applicable hazardous classifica�on ra�ngs.

15. As far as li�s in the hangars, will there be any restric�ons on what type of li�s will be allowed? (type and fuel) Gov Response: Eco friendly preferred, Electric/Propane, No other restrictions.

16. The exis�ng bird ne�ng in the hangar areas, will this be removed prior to work be completed in the areas or will we be working around these?

A-E Response: Refer to keynote D38 on demo RCP’s: Temporarily remove exis�ng bird ne�ng for installa�on of new fan.

17. The conduits feeding the 800A buss ducts and the power converter associated with the 400 Hz system, will this be required to be ran in aluminum conduit or will steel conduit suffice?

A-E Response: U�lize rigid aluminum conduits for these applica�ons.

18. Is there any specific badging/training that will be needed and if so, what would be the cost/ hours needed to get the badging completed?

KO Response: Form 2 is required for Base access, follow those instructions. Follow Sec 00700 and 01000 for any training requirements. No cost to submit Form 2s

27. Specifica�ons and scope of work calls for a phased replacement of exis�ng conven�onal fire alarm in 1st floor only to a new code compliant addressable system and connect exis�ng devises on 2nd floor to the new system. The exis�ng fire alarm is integrated in all phased areas and work will have to be done in 1 phase, covering all areas. With a new system, we recommend that all devices, including the 2nd floor, is replaced to ensure warranty and UL lis�ng combability.

MCS recommends a new No�fier panel with voice evacua�on no�fica�on and a base specified transceiver for bass wide communica�on to be installed using a “Hot swap” method to reduce any fire alarm down�me. The system will be installed in 1 phase only and cover all areas.

A-E Response: Bid as shown on drawings and specifica�ons.

28. Please clarify the quantities of 12 strand OM4 cables as noted on the riser drawing. 4X12F- Is this 4 OM4 fiber optic cables? Also there is a 5X12F. Should we assume there is 4 OM4 MM and 5 OM4 MM fiber routing from the 1st floor comm rooms to the 2nd floor comm room?

A-E Response: 4X12F = 4 OM4 cables. 12 Strand Mul�mode Fiber is equivalent to one OM4 Cable. (Each cable should have 12 strands)

29. Are all existing block wall penetrations at removed ductwork required to be infilled as per detail

A1/S-401 (note they can only be identified on drawing MD110a, MD110b, MD110c, and MD110d)?

A-E Response: Yes, all penetra�ons at removed ductwork (that isn’t being reused or modified) will need to be infilled. Refer to forthcoming Amendment structural sheets where this is addressed.
