48 C.F.R. § 501.104 – Applicability.

(a) General. The GSAR applies to contracts for suppliers or services, including construction.
(b) Acquisition of leasehold interests in real property. Part 570 establishes rules for the acquisition of leasehold interests in real property. Other provisions of 48 CFR chapter 5 (GSAR) do not apply to leases of real property unless specifically cross-reference in part 570.
(c) Relationship to state. Some GSAR rules implement and interpret laws and other authorities affecting procurement. A GSAR rule specifically directed by statute has the force and effect of law.
