GSA is responsible for two acquisition regulations.
The Federal Acquisition Regulation (FAR) was established to codify uniform policies for acquisition of supplies and services by executive agencies. It is issued and maintained jointly, pursuant to the Office of Federal Procurement Policy (OFPP) Reauthorization Act, under the statutory authorities granted to the Secretary of Defense, Administrator of General Services and the Administrator, National Aeronautics and Space Administration. Statutory authorities to issue and revise the FAR have been delegated to the Procurement Executives in Department of Defense (DoD), GSA and National Aeronautics and Space Administration (NASA).
The Federal Acquisition Policy Division writes and revises the FAR to implement laws, executive orders, other agency regulations, and governmentwide policies. The Division coordinates with the Office Federal Procurement Policy, other agencies, and various stakeholders in a highly collaborative and deliberative process to support the maintenance of the FAR and fulfill public policy objectives.
Information on FAR cases currently under development is available in the Open FAR Case Status Report.
The GSA Acquisition Regulation System consists of:
The General Services Office of Acquisition Policy (OAP) writes and updates both the GSAR and the GSA Acquisition Handbook. OAP is the sole office responsible for issuing GSA acquisition policy.
