Contractor RFI questions & Government Response Aug 28 2018

Q1: Volume 1 of 3 of the specifications appears to be missing on FBO. I would assume that is where the bidding instructions reside. Would you be able to provide or post that?

A1: The Working Drawings are considered Volume 1 of 3 (attachment 4 of the solicitation).

Q2: Is there a project key for projnet for the above listed project?

A2: The Project Solicitation and all associated documents were provided on FBO. Neither the Base CE nor Contracting office utilizes Projnet for Contract Management communication.

Q3: Will you please confirm that the 'Schedule of Prices' in Item 17 of the SF1442 refers to the AF Form 3052 and therefore AF Form 3052 is required with the bid in addition to the Schedule of Bid Items with lump sum?

A3: The Schedule of Prices in Item 17 of the SF1442 does not refer to the AF3052, however, the AF3052 IS REQUIRED to be submitted with the bid in addition to the Bid Schedule (attachment 9).

Q4: Will the vertical lift modules be part of the construction scope?

A4: NO-the Vertical Storage Lift Units will not be part of this project. The Vertical Storage Lift Units are considered equipment and will be purchased and installed by the Government within a separate contract.
