To better meet the needs of GSA’s customer agencies, a deviation to FAR Part 51.1 has been approved to expand the authority of contractors to use GSA sources of supply placed on a time-and-materials (T&M)/labor-hour (LH) basis. Federal Government contracting officers have been authorized to give all GSA contractors access to the Federal Supply Schedule (FSS) and GSA Global Supply Programs when deemed appropriate for fulfillment of their agency requirements. Please note that the FSS Program is inclusive of those Schedules managed by the Department of Veterans Affairs.
