Please confirm that the only 50 STC-rated walls are the boundary walls of the (2) ICD 705 secure suites, and that none on the rooms inside the secure secure suites require 50 STC separation from each other (for example, MPR-Large to Office-1). SOW 1.3.6.5 indicates to provide 50 STC doors to mid-size mission planning rooms (as well to the secure boundary openings), but 1.3.6.4 only requires 50 STC walls for the secure boundary. If there are additional spaces within the suites that require acoustical separation, please identify rooms and define the acoustic rating required.

SOW 1.3.6.4 and 1.3.6.5 ICD 705 / USER Correct. The only 50 STC-rated walls are the boundary walls.

38 17-Jul-25

Existing Roof Conditions: The existing (and new) roof above the secure suite areas are considered to be the "true ceiling" which is required to meet the same 50 STC performance as the secure boundary walls; per as-built drawings provided, we know the existing roof was replaced in 2003, but the drawings only describe 90 MIL EPDM membrane over R-30 insulation - there is no mention of a coverboard as part of the assembly, and the set does not include any roof details. It is unclear whether this roof assembly, which is indicated to be repaired/reused will meet the 50 STC requirement. Can the Government provide the shop drawings for the roof replacment project, so we can determine the acoustical performance of the roof? If not, provide direction for acoustical mitigation.

The design-build construction solicitation currently employs sealed bidding under FAR Part 14.

Given the substantial design effort anticipated (e.g., analyzing the 35% design, running preliminary calculations, and validating SCIF requirements) necessary to develop pricing and considering the expected level of interest from industry, could the Government explain its rationale or internal analysis for choosing sealed bidding instead of using FAR Part 15 and the mandatory two-phase design-build procedures authorized by 10 U.S.C. § 3241 and outlined in FAR Subpart 36.3?

Solicitation (SF 1442) CONTRACTING

FAR 6.401 (a) states Contracting Officers shall solicit sealed bids using procedures at FAR Part 14 if the conditions identified are met. The conditions at FAR 6.401 were met: Time permits the solicitation, submission, and evaluation of sealed bids; award will be made on the basis of price;

the SOW provided is comprehensive, negating the necessity for Discussions; and there is reasonable expectation of receiving more than one sealed bid.

86 17-Jul-25

If the Government concluded that the two-phase design-build procedures were not required, can you describe how the current FAR Part 14 approach (which prohibits technical discussions, clarifications, and price-realism evaluations) will mitigate key performance risks (design assumptions, SCIF security compliance, unrealistically low pricing) and ensure award of the most advantageous contract?

Solicitation (SF 1442) CONTRACTING

To further mitigate risk to the government, Offerors were provided an opportunity to view the site and ask technical questions and/or address ambiguities during this RFI process that would otherwise prohibit designing and proposing to the Statement of Work as provided. Any bid may be rejected if the Contracting Officer determines the bid is unreasonable as to price, or the prices for any line items are materially unbalanced. Awardee must also conform to the Invitiation for Bid, and be considered responsible in accordance with FAR 9.104-1. An offeror who does not meet the general standards of FAR 9.104-1 may be considered ineligible for award.
