Question 1 (Q1): Please confirm whether Solicitation W9123826QA031 requires a bid bond with the quote or performance and payment bonds after award. We did not identify a specific bonding requirement in the current solicitation and want to confirm before proceeding with pricing.

Answer 1 (A): The bonding requirement was not included in solicitation because it is not required for this Supply with Installation (Service) type contract.

Q2: Is there an engineers estimate for this project?

A2: There is no engineering estimate to state a contract Magnitude value range statement, because this is a Service contract.

Q3: Prefabricated Restroom Building Please provide the basis-of-design manufacturer/model, floor plan, or approved equivalent for the required prefabricated concrete restroom/shower building. If no specific manufacturer/model is required, please confirm that the Contractor is responsible for selecting and furnishing a building that meets the Performance Work Statement (PWS).

Please also clarify whether the stated 26 ft x 30 ft footprint is an approximate size, maximum size, or required footprint, and whether the minimum of four individual unisex restroom/shower combinations is the exact configuration required for bidding.

A3: Yes, contractor is responsible for selecting and furnishing building that meets PWS requirements. The 20X30 is the required footprint with 4 unisex bathrooms per PWS paragraph
