D.C. Mun. Regs. tit. 27, § 1630
1630.1 The contracting officer shall notify each offeror whose proposal is determined to be unacceptable before award unless disclosure might prejudice the best interests of the District.
1630.2 If the proposal evaluation period for a solicitation is expected to exceed thirty (30) days, or when a limited number of offerors have been selected as being within the competitive range, the contracting officer, upon determining that a proposal is unacceptable, shall promptly notify the offeror.
1630.3 The contracting officer shall award a contract with reasonable promptness to the successful offeror by transmitting written notice of the award to that offeror.
1630.4 Promptly after the award of each contact, the contracting officer shall notify unsuccessful offerors in writing, unless pre-award notice was given.
1630.5 If a contract is awarded on a basis other than price alone, the contracting officer shall provide a debriefing for any unsuccessful offeror that submits a written request for debriefing, unless the Director determines that to do so is not in the best interests of the District.
1630.6 If a debriefing is held, debriefing information shall include the District's evaluation of the significant weak or deficient factors in the proposal. However, point-by-point comparisons with other offerors' proposals shall not be made.
1630.7 Debriefing shall not reveal the relative merits or technical standing of competitors or the evaluation scoring.
