(a) If an offeror’s proposal is eliminated or otherwise removed from the competitive range, no further revisions to that offeror’s proposal shall be accepted or considered.

(b) The contracting officer may request or allow proposal revisions to clarify and document understandings reached during negotiations. At the conclusion of discussions, each offeror still in the competitive range shall be given an opportunity to submit a final proposal revision. The contracting officer is required to establish a common cut-off date only for receipt of final proposal revisions. Requests for final proposal revisions shall advise offerors that the final proposal revisions shall be in writing and that the Government intends to make award without obtaining further revisions.
