29 CFR § 10.3 - Coverage.
(ii) It is a contract for services covered by the Service Contract Act;
(iv) It is a contract entered into with the Federal Government in connection with Federal property or lands and related to offering services for Federal employees, their dependents, or the general public; and
(b) For contracts covered by the Service Contract Act or the Davis-Bacon Act, this part applies to prime contracts only at the thresholds specified in those statutes. For procurement contracts where workers' wages are governed by the Fair Labor Standards Act, this part applies when the prime contract exceeds the micro-purchase threshold, as defined in 41 U.S.C. 1902(a).
(c) This part only applies to contracts with the Federal Government requiring performance in whole or in part within the United States. If a contract with the Federal Government is to be performed in part within and in part outside the United States and is otherwise covered by the Executive Order and this part, the minimum wage requirements of the Order and this part would apply with respect to that part of the contract that is performed within the United States.
(d) This part does not apply to contracts for the manufacturing or furnishing of materials, supplies, articles, or equipment to the Federal Government that are subject to the Walsh-Healey Public Contracts Act, 41 U.S.C. 6501 et seq.
