Laughlin AFB T-1 Sunshades Site Visit Questions and Answers Solicitation FA309919RA003 Question: Is Solicitation FA309919RA003 just to include the cost of the “infrastructure” for the T-1 Sunshades or is it to also include the cost to design and build the “T-1 Sunshades”?

Answer: The design for this project has already been completed. This solicitation is for the construction of the real property infrastructure and equipment installation of the T-1 Sunshades.

Question: Standard Form 1442 only provides for one (1) cost line item and it is fairly well noted as “utility infrastructure”. Will additional cost line items be added to itemize cost for the remaining work?

Answer: Regarding materials, there are two portions of funding that are separate: utility infrastructure (what the Contractor sees in the RFP) and equipment (already has been funded by another Government organization). Regarding labor, this construction contract will ensure that the Contractor is responsible for installing both the utility infrastructure (what the Contractor is bidding for here) and equipment (already been paid for by another Government organization).
