Section 873.114 - Best value pool(a) Without regard to FAR 15.306(c), the contracting officer may determine the most highly rated proposals having the greatest likelihood of award based on the information or factors and subfactors in the solicitation. These vendors constitute the best value pool. This determination is within the sole discretion of the contracting officer. Competitive range determinations are not applicable to acquisitions under this part 873. (38 U.S.C. 8153 )(b) In planning an acquisition, the contracting officer may determine that the number of proposals that would otherwise be included in the best value pool is expected to exceed the number at which an efficient, timely, and economical competition can be conducted. In reaching such a conclusion, the contracting officer may consider such factors as the results of market research, historical data from previous acquisitions for similar services, and the resources available to conduct the source selection. Provided the solicitation notifies offerors that the best value pool can be limited for purposes of making an efficient, timely, and economical award, the contracting officer may limit the number of proposals in the best value pool to the greatest number that will permit an efficient competition among the proposals offering the greatest likelihood of award. The contracting officer may indicate in the solicitation the estimate of the greatest number of proposals that will be included in the best value pool. The contracting officer may limit the best value pool to a single offeror. (38 U.S.C. 8153 )(c) If the contracting officer determines that an offeror's proposal is no longer in the best value pool, the proposal shall no longer be considered for award. Written notice of this decision must be provided to unsuccessful offerors at the earliest practicable time. (38 U.S.C. 8153 )
