29 CFR 4.132: Services and other items to be furnished under a single contract.

If the principal purpose of a contract is to furnish services through the use of service employees within the meaning of the Act, the contract to furnish such services is not removed from the Act's coverage merely because, as a matter of convenience in procurement, the service specifications are combined in a single contract document with specifications for the procurement of different or unrelated items. In such case, the Act would apply to service specifications but would not apply to any specifications subject to the Walsh-Healey Act or to the Davis-Bacon Act. With respect to contracts which contain separate specifications for the furnishing of services and construction activity, see § 4.116(c).
