FAR 15.5—Subpart 15.5

Definition.

FAR 15.501 is a short definitional provision in the negotiated procurement subpart. It does not create a new substantive rule; instead, it tells readers that the term “day,” as used in this subpart, has the meaning given in FAR 33.101. Its purpose is to ensure consistent counting of time periods wherever the subpart uses deadlines, response periods, or other time-based requirements. In practice, this means contracting officers, offerors, and contractors must look to FAR 33.101 for the controlling definition rather than assuming that “day” means a calendar day, business day, or some other measure. This cross-reference matters because time calculations can affect proposal submissions, discussions, notices, and other procedural rights and obligations under Part 15. The section is brief, but it is important because misunderstanding the definition of “day” can lead to missed deadlines, disputes over timeliness, or procedural errors in source selection actions.

Applicability.

FAR 15.502 explains when the source-selection and proposal-related procedures in Subpart 15.5 apply. It states that the subpart governs competitive proposals under FAR 6.102(b) and also applies to acquisitions using a combination of competitive procedures under FAR 6.102(c). The section also points contracting officers to specific procedures in FAR 15.504, 15.506, 15.507, 15.508, and 15.509 and says those procedures should be followed, with reasonable modification, for sole-source acquisitions and for the limited acquisition situations described in FAR 6.102(d)(1) and (2). In practice, this section is a scope-and-cross-reference rule: it tells agencies when the formal proposal process framework is mandatory, and when it should be adapted rather than ignored. For contractors, it signals that even noncompetitive or special acquisition methods may still use many of the same proposal-handling and debriefing-related procedures. For contracting officers, it is a reminder to apply the right level of process based on the acquisition method and to preserve fairness, documentation, and consistency.

Notifications to unsuccessful offerors.

FAR 15.503 governs when and how contracting officers must notify unsuccessful offerors during negotiated procurements. It covers two major stages: preaward notices when an offeror is excluded from the competitive range or otherwise eliminated, and special preaward notices for certain small business programs, including small business set-asides, HUBZone, service-disabled veteran-owned small business, and women-owned small business procedures. It also covers postaward notices to unsuccessful offerors in the competitive range, including the timing of the notice, the required contents, and the limits on what information may be disclosed. In addition, it addresses when postaward information must be provided upon request in simplified acquisitions and to offerors previously given a preaward exclusion notice. The section exists to promote transparency, preserve fairness in source selection, and give unsuccessful offerors enough information to understand the outcome without revealing protected source selection or proprietary information. In practice, it helps contracting officers manage debriefing-related communications, protect confidential business information, and comply with statutory notice requirements tied to negotiated procurements and certain small business programs.

Award to successful offeror.

FAR 15.504 explains how a contracting officer formally makes award to the successful offeror after source selection. It covers the basic method of award delivery, when the award document must be signed by both parties, how to handle awards for less than all items when some items are withheld for later award, and what must appear on the first page of the award document when the government does not use OF 307, SF 26, or SF 33. In practice, this section is about making the award legally clear and administratively complete so there is no doubt about what the government accepted, what the contractor agreed to, and whether any additional items may still be awarded later within the proposal acceptance period. It also protects both sides when the award terms differ from the offeror’s latest signed proposal or written amendments by requiring explicit contractor assent. For contracting officers, this section is a checklist for award execution and documentation; for contractors, it signals when a signature is required and when the award may still be incomplete because some items are being held for possible later award.

Preaward debriefing of offerors.

FAR 15.505 explains when and how an offeror may receive a preaward debriefing after being excluded from the competitive range or otherwise removed from the competition before award. It covers the 3-day deadline for requesting the debriefing, the offeror’s option to delay the debriefing until after award, the effect of that choice on protest timeliness, and the rule that an offeror is entitled to only one debriefing per proposal. The section also addresses the contracting officer’s duty to make every effort to debrief promptly, the limited ability to delay or refuse a debriefing for compelling Government reasons, and the requirement to document any delay in the contract file. It specifies acceptable debriefing formats, who should chair and support the session, the minimum content that must be provided, and the information that must not be disclosed. Finally, it requires an official summary of the debriefing to be placed in the contract file. In practice, this section is important because it balances transparency for unsuccessful offerors with protection of source selection integrity and other offerors’ proprietary information, while also affecting protest rights and deadlines.

Postaward debriefing of offerors.

FAR 15.506 explains how postaward debriefings work for offerors after a contract award. It covers who is entitled to a debriefing, the 3-day written request deadline after award notice, the preferred timing for the debriefing, what happens when an offeror requested a postaward debriefing instead of a preaward debriefing, and how delayed debriefings or untimely requests affect protest timeliness. It also addresses the acceptable formats for debriefings, who should chair and support them, the minimum information the Government must provide, the limits on what may not be disclosed, and the requirement to place an official summary in the contract file. In practice, this section is important because a debriefing is often the first formal explanation an unsuccessful offeror receives about why it lost and how the award decision was made. It also matters because debriefing timing can affect the window for filing a bid protest, so both offerors and contracting officers must track dates carefully and understand when a debriefing is timely, delayed, or merely accommodated. The rule balances transparency and fairness against the need to protect source selection integrity, proprietary information, and other protected data.

Protests against award.

FAR 15.507 addresses how protests against award are handled in negotiated acquisitions and what information must be shared if a protest leads the agency to redo the competition within one year after award. It ties award protests to the procedures in FAR part 33 and encourages agencies to use agency protest procedures that include the alternative dispute resolution provisions of Executive Order 12979 for both preaward and postaward protests. The section also covers two specific corrective-action scenarios after a protest: issuing a new solicitation on the protested award, or issuing a new request for revised proposals. In those cases, it requires the contracting officer to provide certain information to the appropriate parties, including debriefing information about the successful offeror’s proposal and other nonproprietary information that would have been given to the original offerors. In practice, this section is about fairness, transparency, and maintaining competition integrity when an award is challenged and the agency decides to reopen the acquisition.

Discovery of mistakes.

FAR 15.508 addresses what happens when a contractor discovers a mistake in its proposal only after award has already been made. The section is very short, but it points to an important remedial process: the mistake must be handled substantially under the same procedures used for mistakes in bids at FAR 14.407-4. In practice, this means the contracting officer and contractor must treat the issue as a post-award mistake claim, with careful review of the facts, the timing of the discovery, the nature of the error, and the evidence supporting the alleged mistake. The section exists to provide a fair mechanism for correcting or resolving genuine proposal mistakes without undermining the integrity of the award process. It matters because post-award mistakes can affect price, performance obligations, and contract administration, and they often require a formal record showing whether relief is appropriate and what form it should take.

Forms.

FAR 15.509 explains which contract award forms may be used for negotiated procurements when the Government and contractor will both sign a single award document. It specifically addresses Optional Form (OF) 307, Contract Award; Standard Form (SF) 26, Award/Contract; and SF 33, Solicitation, Offer and Award, and it also tells contracting officers what to do if they do not use one of those forms. The section’s purpose is to ensure the award document clearly reflects the agreement and the award in a format suitable for bilateral signature, while avoiding form-related errors that can create ambiguity or administrative problems. In practice, this means the contracting officer must choose an appropriate form for the award method, use SF 26 correctly by leaving block 18 unused in negotiated procurements, and include the OF 307 agreement-and-award language in any alternate award document. For contractors, the section matters because it affects how the final contract is executed, what document controls the award, and whether the signature process properly captures the parties’ agreement.
