(b) The following procedure applies when contracting by sealed bidding:

(1) If a project wage determination for the primary site of the work expires before bid opening, or if it appears before bid opening that a project wage determination may expire before award, the contracting officer shall request a new determination early enough to ensure its receipt before bid opening. If necessary, the contracting officer shall postpone the bid opening date to allow a reasonable time to obtain the determination, amend the solicitation to incorporate the new determination, and permit bidders to amend their bids. If the new determination does not change the wage rates and would not warrant amended bids, the contracting officer shall amend the solicitation to include the number and date of the new determination.

(2) If a project wage determination for the primary site of the work expires after bid opening but before award, the contracting officer shall request an extension of the project wage determination expiration date from the Administrator, Wage and Hour Division. The request for extension shall be supported by a written finding, which shall include a brief statement of factual support, that the extension is necessary and proper in the public interest to prevent injustice or undue hardship or to avoid serious impairment of the conduct of Government business. If necessary, the contracting officer shall delay award to permit either receipt of the extension or receipt and processing of a new determination. If the request is granted, the contracting officer shall award the contract and modify it to apply the extended expiration date to the already incorporated project wage determination. (See 43.103(b)(1).) If the request is denied, the Administrator will proceed to issue a new project wage determination. Upon receipt, the contracting officer shall process the new determination as follows:

(i) If If the new determination for the primary site of the work changes any wage rates for classifications to be used in the contract, the contracting officer may cancel the solicitation only in accordance with 14.404-1. Otherwise the contracting officer shall award the contract and incorporate the new determination to be effective on the date of contract award. The contracting officer shall equitably adjust the contract price for any increased or decreased cost of performance resulting from any changed wage rates.

(ii) If the new determination for the primary site of the work does not change any wage rates, the contracting officer shall award the contract and modify it to include the number and date of the new determination. (See 43.103(b)(1).)
