48 C.F.R. § 22.1015
If the Department of Labor discovers and determines, whether before or after a contract award, that a contracting officer made an erroneous determination that the Service Contract Labor Standards statute did not apply to a particular acquisition or failed to include an appropriate wage determination in a covered contract, the contracting officer, within 30 days of notification by the Department of Labor, shall include in the contract the clause at 52.222-41 and any applicable wage determination issued by the Administrator. If the contract is subject to 41 U.S.C. 6707(f) , the Administrator may require retroactive application of that wage determination. The contracting officer shall equitably adjust the contract price to reflect any changed cost of performance resulting from incorporating a wage determination or revision.
