01 General Requirements

3. Please verify that the government will furnish all CAD files that are associated with the current bid drawings. We will utilize them to complete the overall design.

A. Yes. The government will furnish all CAD files that are associated with the current bid drawings.

4. Please verify that the basis of design shall be followed as closely as possible. In other words please verify that a CMU, Brick Veneer, Standing Seam Metal Roof is the required exterior construction type. On past projects competitors were permitted to construct pre cast non‐conventional structures that did not follow the SOW or bid drawing intent. It would make it very difficult for the government to compare apples to apples.

A. Yes. The basis of design shall be followed as closely as possible i.e., CMU, Brick Veneer, Standing Seam Metal Roof is the required exterior construction type.

5. Is the 144r available for this project? If so will it be distributed with an update?

A. See attached 144r.

6. Will a Life Safety Analysis be required of the contractors design team?

A. No. A Life Safety Analysis will NOT be required of the contractors design team.

22 Plumbing

7. The plumbing specification in the project solicitation is not downloadable. Will a plumbing specification be provided in a solicitation update?

A. See attached Plumbing spec, UFGS 22 00 00 Plumbing, General Purpose.

23 HVAC

8. The ERV appears to be quite large and may not fit in the mezzanine space. Will a value engineered HVAC system be acceptable if it meets current scope, Fort Benning, and Energy Code requirements?

A. Yes. A value engineered HVAC system WILL be acceptable if it meets current scope, Fort Benning, and Energy Code requirements.

26 Electrical

9. Will a lightning protection system with UL‐Master Label be required for the latrine annex?

28 Electronic Safety and Security

10. Will FA or MNS systems be required for this facility? None are shown in the SOW or bid drawings.

A. No. An FA or MNS systems will NOT be required for this facility.

11. Attached please find the dimensions of the HVAC unit to be placed on the mezzanine. Given the size of the unit, it will need to be set prior to installing roof trusses or a structural opening large enough to install the unit will need to be considered. The unit has a ten (10) to twelve (12) week lead time after shop drawing approval. This will add barriers to the ability to complete the project in 180 days. Plus, once installed the 4x4 removable ceiling will not be adequate for future equipment removal/replacement.

a. Should we proceed as shown?

A. A value engineered HVAC system WILL be acceptable if it meets current performance‐based scope, Fort Benning, and Energy Code requirements.
