6. Question: Who is responsible for removing the existing alarms or are they to remain in place? If new alarms are to be provided, what do they connect to?

Answer: The contractor removes alarms for spaces being remodeled. See Drawing ED100, flag notes 5, 6 and 14.

7. Question: What is to be done with the restroom floors as they connect to raised flooring? It also calls for tile so is the intent to lay tile over the raised flooring?

Answer: Restroom floors shall be kept separate from the Raised Access Flooring. Tile only occurs on the Restroom Floor structure. Provide a transition strip between Restroom floor finish and adjacent floor finish as specified.

8. Question: What is the detail for floor drains within raised flooring as the floor can't be sloped to the drain?

Answer: Locate the floor drains below the raised floor. The purpose of these floor drains are for the condensate drainage for the portable AC units. These units are for emergency use only. When the unit is in use, the drain line is to be routed to the floor drain through an open floor tile. Provide flexible drain line from portable unit with sufficient length to route below raised floor.

9. Question: The waste piping will need to be installed under the floor at each level. Will we have access during normal business or will it need to be scheduled on nights or weekends?

Answer: Shutting down rest rooms in occupied areas will require work outside of core business hours.

10. Question: Where is the fin tube heaters water piping and is it accessible during normal business hours.

Answer: Piping is located in the ceiling of the floor below. If the space is unoccupied assume core business hours, however if occupied, than the time may be during core business hours but if the mission requires other than normal duty time than the contractor will bid accordingly.

11. Question: It was discussed the south dock is shut down and would need to use the J dock which is substantially further. Please advise

Answer: South dock should be reopened before the start of this contract. It should be reopened before 1 Nov 20.

12. Question: Room 2F1 Communications Closet. Is the alarm to remain active? If so, who is responsible for rerouting cables to alternate communication closet? If it will be done under a separate contract, will it be complete prior to award?

Answer: The rerouting of the cabling is part of this contract. The alarm can be turned off each day while the contractor works to relocate the server and wiring. Reference sheets 58 & 59.

13. Question: What is to be done with the fire alarm control panel in BF24?

Answer: Panel shall remain in place and shall be protected throughout construction.

14. Question: The current fire sprinkler heads in the hallways are white concealed and there are chrome semi recessed in the rooms. Please advise if you want to keep the style in each location or should they all be concealed?

Answer: Provide white concealed heads.

15. Question: What is to be done with the existing electrical panel in 2F18 as it's not shown on the prints?

Answer: Record drawings and field notes do not indicate an electrical panel in 2F18. Remove panel and associated feeder or relocate panel to Room 2F22H. If the panel is removed, active circuits remaining after construction will need to be transferred to the nearest panel board with adequate capacity. Coordinate with Contracting Officer Representative (COR) prior to performing work. COR will be Dave Lott.

16. Question: Is the freight elevator near the south dock operational as there is a sign that says it doesn't work?

However, it was being used. Please advise

Answer: The freight elevator shall be available for use during this contract.

17. Question: Is there contact information for the person that is in charge of keys and cylinders for this project so we can find out information on the existing key and lock manufacture. This is referring to specs, page 5 section

2.3.6 and 2.3.8.

Answer: Please coordinate with CE project manager during construction. We will work with the base locksmith.

18. Question: Reference Drawings, sheet E-402, Note #1. Does the project have a separate shielding specification?

Often there is a shielding-specific section detailing project requirements, etc.

Answer: There is no shielding spec. Comply with MIL-STD 188-125-1.

19. Question: Reference Drawings, sheet E-402, Note #1. Armag includes shielding effectiveness testing IAW MIL-STD-188-125-2. “-2” is used for mobile applications while “-1” is used for fixed. I had interpreted this installation as fixed (in its final configuration). Is there a reason why it should be considered mobile?

Answer: No. Use the fixed standard.

20. Question: Reference Drawings, sheet E-402, Note #1. Armag includes shielding effectiveness (SE) testing but does not seem to include PCI testing of the HEMP electrical filters. Both forms of testing would be needed to meet the requirements of the MIL-STD. The SE and PCI testing are Appendix A and Appendix B, respectively of the Standard. Are you aware of any reason why PCI testing would not be included?

Answer: No. Include PCI testing to meet the MIL-STD

21. Question: Reference Drawings, sheet E-402, Note #1. Armag notes that SE testing is included but does not specify if the testing is “Acceptance” or “Verification” or both. Each type is completed with slightly different objectives in mind, per the Standard. I assume they mean Acceptance. Acceptance, in this case, would generally be completed at the factory while Verification would be completed onsite, after installation is completed and the system is operations. Acceptance would be needed, at minimum, but Verification is often required as well and is good practice. We can perform both but it is not certain what the expectation is here. Same goes for PCI testing – there is Acceptance and Verification.

Answer: Provide both acceptance and verification testing.

22. Question: Reference Drawings, sheet E-402, Note #1. Armag notes that WG-F12 waveguides are included for fiber. From our experience, these types of waveguides are used for higher-performing applications than is required per MIL-STD-188-125. Can you confirm that the performance range required here is consistent with MIL-STD-188- 125 and nothing else?

Answer: There are no HEMP requirements in addition to complying with the MIL-STD.

22. Question: Reference Drawings, sheet E-402, Note #1. Armag includes a ¼” steel exterior. This thickness of steel would not be necessary to meet only the MIL-STD-188-125 shielding requirement and could add unnecessary weight if not needed. Do you know if there are other reasons why ¼” thick steel may be included? Is there a ballistics requirement for this?

Answer: No.

23. Question: Reference Drawings, sheet E-402, Note #1. Understand the enclosure is to be “weatherproof”. Are there specific requirements of standards for this? Will testing need to be performed to validate operate-through certain environmental conditions?

Answer: “Weatherproof” requires an outdoor enclosure suitable for installation at the project location. Testing shall be as required by the MIL-STD.

24. Question: Reference Drawings, sheet E-402, Note #1. Does the enclosure need to be provided with any specific structural or seismic certifications?

Answer: Coordinate with building code and UFC documents for installed location.

25. Question: Confirm that the Power Filters listed on Drawing Sheet 47 of 64, Flag Note 1, are to be HEMP power filters. We would like confirmation that these should be compliant to MIL-STD-188-125-1 requirements as pricing for non-HEMP filters can vary significantly.

Answer: HEMP power filters are required.

26. Question: Assuming the filters listed in the above reference are to perform to HEMP standards, does the government require Acceptance PCI testing per MIL-STD-188-125-1?

Answer: Yes.

27. Question: Assuming the HEMP protected generator shelter is to be performed under MIL-STD requirements, should on-site Acceptance Shield Effectiveness testing, as defined by MIL-STD-188-125-1, be considered a requirement? The intent of this test is to ensure HEMP Critical assemblies such as RF doors, WBCs and removable panels continue to meet minimum thresholds after shipping.

Answer: Yes.

28. Question: Attachment 3, Section 1.2.2 states: “Provide each generator set with power equal to the sum of service load plus the machine's efficiency loss and associated ancillary equipment loads. Rated output capacity shall also consider engine and/or generator oversizing required to meet requirements in paragraph Engine-Generator Parameter Schedule.”

In the Engine-Generator Parameter Schedule, 1.2.1, the section for service load states “See Drawings.” The defined service load for the HEMP protected generator is not summarized in the drawings. Please define this parameter or indicate where it is located in the drawing package, for accurate system sizing. It is our assumption that this is the sum load of Panel 2F22HH on drawing E-502.

Answer: The service load is the sum of the loads on Panel HEMP. Generator shall be 60kW per Drawing E-402, Flag Note 3.

29. Question: It is our assumption that HEMP power and signal filters will be required at the input (Panel HEMP) and output (Panel 2F22HH). Based on these tables: the incoming power will be 3 Phase 4 Wire 208/120V, 200A.

Output power will be 3 Phase 4 Wire, 225A. Please verify.

Answer: Input and output circuits are 200 Amp. Additional output circuits are required per Drawing E-402.

Conductors are increased in size for voltage drop.

30. Question: During the site visit we observed an outbuilding currently installed in the area indicated for installation of this structure. Is it the intent of the contract to place the HEMP protected generator in this location and to remove the shed?

Answer: Locate west of the shed. Coordinate exact location with Government per 1/S-202.

31. Question: Is the desired installation location capable of supporting the structure (weight, vibration, etc.). Is it the intent of the contract to pour a concrete foundation prior to installation?

Answer: See Drawing S-202.

32. Question: Are there any requirements for the addition of HEMP protection on the LOAD being connected to the generator?

Answer: No.

33. Question: Do the conduits connecting the HEMP shelter to existing structures need to be HEMP protected (ex.

continuously welded)?

Answer: No.

34. Question: Does the transfer switch require HEMP protection?

Answer: No. The transfer switch is located within the HEMP-protected enclosure.

35. Question: Which drawings indicate the generator and ATS dimensions?

Answer: Dimensions are not indicated on drawings. Coordinate with equipment suppliers.

36. Question: The solicitation states the that "The space will be classified Top Secret Collateral". Is there a requirement for the prime contractor to have a top-secret facility clearance for this project?

Answer: No

37. Question: Will all rooms be vacated before construction begins?

Answer: yes, assume space will be vacant.

38. Question: Is there any need to phase this project?

Answer: Not necessary.

39. Question: Will the contractor have to demolish the existing furniture?

Answer: Refer to sheet G-001, General Note 15 which states the following: “All furniture not in contract (N.I.C.)

unless otherwise noted, shown dashed. Government will remove and store existing furniture before construction work begins. Systems furniture and files cabinets are to be removed prior to 1 Oct 20.

40. Question: Does the Government already have a contract in place to supply new furniture?
