A. They will have to enter through the Pearl Harbor Gate, and be announced 2 hours prior to their arrival.

7. Q. We assume this project may have unannounced ramp freezes, can you explain how much downtime we should include in our assumptions for one work week? On average, how many hours and how many stoppages per week should we expect and build into our estimate?

A. As long as your personnel are inside the building, they can continue working. Assume

3 ramp freezes per week, 1 hour each.

8. Q. Will anything be brought into the warehouse portion of the building that would be considered secretive (and require us to stop work for an extended period)?

A. No.

9. Q. Please confirm the intention is to replace UH-3 in the 2nd floor Mechanical room

(not 1st floor mechanical room as referenced in the SOW).

A. Yes, SOW says "Replace 5 unit heaters:...Mezzanine and 1st floor Mechanical Rooms

(UH-3)"

10. Q. Will any work be required to be done during off hours?

11. Q. The SOW calls to replace the (DH-3) door heaters at the two ramp doors. Please confirm that door heaters for the other doors (DH-1) and (DH-2) are not required to be replaced.

A. ALL door heaters (DH-1: quantity 2, DH-2: quantity 4, DH-3: quantity 4), including their fans ARE required to be replaced. The SOW will be revised accordingly.

12. Q. If we are replacing the existing gas-fired unit heaters with and infrared system, the infrared heaters will uses the concrete floor as a heat sink and as long the doors are not left open a lot in the winter, the DH-1 and DH-2 may not be necessary.

A. All door heaters are necessary.

13. Q. Is the scope of work for DH-3 replacement limited to just an equipment replacement? Are we reusing the existing duct and grilles, or are we to replace the whole assembly?

A. Reuse all the existing duct and grilles.

A. Yes, SOW says “…and 1st floor Mechanical Rooms (UH-3).”

15. Q. For the R6 insulated ceiling tiles, will insulating the ceiling with loose insulation batts be acceptable or it is desired to have an insulated ceiling tile that provides the

R6 insulation.

A. The latter: insulated ceiling tiles that provides the R6 insulation.

16. Q. It is not mentioned in the SOW, however, if we are replacing the heat tracing, that piping should also be provided with new insulation and aluminum jacketing. Is this to be included?

A. PoP = 180 days. The SOW will be revised accordingly.

19. Q. Please provide Mechanical As-Built Drawings for Building 1900.

A. Done.

20. Q. Please confirm that the Drawings provided with Amendment 0001 accurately reflect the existing building. The concern is the arrangement of the 2nd floor and the

Question: Please advise if the Owner will provide CAD files (drawings) and Word files (specifications) for the Contractor’s use in generating the required Design

Documents.

A. USAF does not have the original CAD drawings of this building. We do have very basic floor plans created by enlisted airmen and will provide those.

A. No, replace the ceiling grids.

23. Q. Please provide a schedule or list showing all mechanical equipment items to be replaced. Per discussions during pre-proposal site visit, the specific quantities required for new/replacement “high bay heaters” and “door heaters” is unclear.

A. See answers to questions 9 and 11. Also, in SOW: “High bay:...Replace high bay heaters (UH-1 and -2) with a gas infrared heating system”

24. Q. Since this is a “replacement-in-kind” project, may ALL existing conduit and wire be reused and extend final connections as necessary?

Boxes?

41. Q. Are the building’s original Arch/Struct drawings available? Building construction has a large impact on the Chiller sizing. For example, a roof replacement with an insulated roof may make the chiller over-sized at this point.

A. See answers to question 21.
