About this agency
GSA Office of Administrative Services is a civilian sub-agency within the General Services Administration that procures facilities, information technology infrastructure, and operational support services for GSA regional operations and administrative functions. The Office has awarded 689 federal contracts since 2008, with combined potential value of $259.8 million and $158.9 million obligated to date. Contract award volume has declined materially over the past five years — 29 awards in 2022, 27 in 2023, 21 in 2024, 10 in 2025, and 6 year-to-date in 2026 — indicating a downward trend in procurement activity.
Competition among prime contractors is highly fragmented. Over the last five years, the top five primes by award count hold 27 percent of recent awards; Xerox Corporation leads with 9 awards worth $2 million in combined potential value, followed by Canon U.s.a., Inc. and Corporate Interiors Inc. with 5 awards each. By potential value, the top five cover only 3 percent of combined value over the window, with Consec Solutions Inc. ($2.4 million across 2 awards) and Xerox Corporation ($2 million across 9 awards) as the largest individual contractors. The remaining 194 prime contractors awarded are spread across the portfolio with minimal concentration. Among the 199 distinct primes, 88 percent of awards carry no set-aside designation. Small-business awards comprise 8 percent of volume (58 awards), with smaller shares of 8(a) sole source (1 percent, 6 awards), woman-owned small business (0 percent, 3 awards), and scattered individual awards in competitive 8(a), HUBZone, and economically disadvantaged woman-owned small business sole source categories.
Recent contract opportunities reflect GSA IT and facilities infrastructure needs. The most recently posted solicitation, Region 8 ROB RIC HVAC Support Services (47QACB26R0004), was issued as a 100 percent small-business set-aside on a competitive basis with a due date of September 22, 2026. A related Request for Information (RFI1835325) sought vendor interest in HVAC and hardware maintenance support for the Region 8 Regional Information Center as market research prior to the formal solicitation, with RFI due date September 10, 2026.
