CONTRACTOR Q&A’s

Replace DHW North Check Valves

Q&A No. 1: We are contacting you to request clarification regarding the bid bond, as in the SF 1449 the bid bond is not required, however in page 16 of the solicitation the bid bond is required to be mailed before the response due date. Would you please clarify if the bid bond required for this project?

Answer No. 1: As clearly stated on page 1 of the SF1442 section 12a bonds are not required.

Additionally, please refer to section 4.5 Clause 52.228-13 Alternative payment protections starting on page 35.
