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 Sec. 4.116(c).
