(c) The following procedure applies when contracting by negotiation:

(1) If a project wage determination will or does expire before contract award, the contracting officer shall request a new wage determination from the Department of Labor. If necessary, the contracting officer shall delay award while the new determination is obtained and processed.

(2) The contracting officer need not delay opening and reviewing proposals or discussing them with the offerors while a new determination for the primary site of the work is being obtained. The contracting officer shall request offerors to extend the period for acceptance of any proposal if that period expires or may expire before receipt and full processing of the new determination.

(3) If the new determination for the primary site of the work changes any wage rates, the contracting officer shall amend the solicitation to incorporate the new determination, and furnish the wage rate information to all prospective offerors that were sent a solicitation if the closing date for receipt of proposals has not yet occurred, or to all offerors that have not been eliminated from the competition if the closing date has passed. All offerors to whom wage rate information has been furnished shall be given reasonable opportunity to amend their proposals.

(4) If the new determination for the primary site of the work does not change any wage rates, the contracting officer shall amend the solicitation to include the number and date of the new determination and award the contract.
