FAR and DFARS › FAR Part 17: Special Contracting Methods › Subpart 17.8
FAR 17.805 Solicitation provision and contract clauses.
The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.
In plain English
This section tells contracting officers which reverse auction provisions and clauses to include in solicitations and contracts. It matters to contractors because it determines when reverse auction terms will appear in the solicitation or contract you are bidding on or performing. The section itself imposes duties on the contracting officer, not on contractors.
Applies to: Contracting officers using reverse auctions in solicitations and contracts
