Architect of the Capitol

The Architect of the Capitol, a legislative-branch independent agency, procures facilities management, capital construction, and building operations services to manage approximately 18.4 million square feet of congressional building space across over 50 structures and 570 acres in Washington, D.C. The agency operates outside standard federal acquisition regulation (FAR) authority but applies comparable competitive and best-value procedures through its Contracting Manual.

Contract activity at the Architect of the Capitol is minimal by recent standards. The agency awarded 10 contracts between 2010 and 2015, with the most recent award closed on June 29, 2015—over 11 years ago. The portfolio generated $522 thousand in combined award potential value, of which $521 thousand has been obligated. Award cadence shows 2 contracts in 2010, 1 in 2012, 1 in 2013, 5 in 2014, and 1 in 2015. All 10 awards were issued unrestricted, with no set-aside designations. Eight distinct prime contractors were awarded across the portfolio. The agency currently shows no recent contract awards recorded against active files.

Current solicitation activity, however, is robust and signals material procurement intent through 2026–2027. The Architect of the Capitol posted a definitive Solicitation (AOCACB26R0052) due October 29, 2026, for a Management Capacity Study valued at consulting services under Firm-Fixed Price terms to evaluate governance and management capacity supporting a multi-billion-dollar capital construction program. The agency also released a pre-solicitation notice for a Single-Award Task Order Contract (SATOC) Indefinite Delivery/Indefinite Quantity (IDIQ) for Mechanical/HVAC construction work with an estimated ceiling of $250 million, one base year, and nine one-year option periods; Step One issuance was scheduled for late September 2026, with Step Two in November or December 2026. Additional pre-solicitation activity includes sources-sought for Automatic Door Operator inspection and maintenance services (due October 8, 2026) and campus-wide waste collection and disposal services (due October 9, 2026). The agency separately issued a Firm-Fixed Price solicitation for Renewable Energy Certificates (REC) (AOCACB26R0073, amended twice, with quotation due September 16, 2026 at 6:00 PM Eastern Time) to support Capitol Power Plant compliance with the Energy Independence and Security Act of 2007's 7.5 percent renewable-energy requirement. No set-asides are applied to any current opportunity.

The Architect of the Capitol manages and maintains the U.S. Capitol, the Capitol Visitor Center, the Senate Office Buildings, the House Office Buildings, the Supreme Court Building, the Library of Congress, the U.S. Botanic Garden, and the Capitol Grounds
