About Capitol Boiler Works Inc.
Capitol Boiler Works Inc., a Springfield, Virginia–based HVAC and mechanical systems contractor, operates as a for-profit limited liability company providing boiler maintenance, repair, installation, and chilled water system services to federal facilities as a prime contractor on purchase orders and small IDIQs (99% of recent awards). The vendor competes full-and-open; no set-aside designations appear in recent awards.
Capitol Boiler Works has maintained federal contracting relationships since 2001, with a core capability portfolio centered on boiler systems, heating and cooling infrastructure, and facility mechanical maintenance. Concrete recent work includes a $135,755 steam boiler project at Federal Correctional Complex Petersburg (January 2026, ultimate completion September 2026), a $71,685 boiler controls installation at the same facility (February 2026, ultimate completion September 2026), a $25,510 chilled water pump replacement at the Smithsonian Institution's Museum Support Center in Suitland, Maryland (July 2025, ultimate completion December 2025), and a $35,875 chilled water coil replacement on a Smithsonian air handling unit (February 2025, ultimate completion April 2025). All work is performed at the customer facility location with firm fixed-price terms.
Customer concentration is fragmented across 34 distinct federal agencies, with the top five accounting for 39% of awards by count and 48% by potential value. The Department of Justice Bureau of Prisons Federal Correctional Complex Petersburg dominates both volume and dollars (13 awards, $682 thousand combined potential value), followed by the Smithsonian Institution (25 awards, $443 thousand), the Department of Justice Drug Enforcement Administration (5 awards, $243 thousand), the Department of Agriculture Agricultural Research Service (7 awards, $120 thousand), and the Department of Justice Federal Bureau of Investigation (8 awards, $103 thousand). The vendor places task orders on the GSA Multiple Award Schedule (4 task orders) and several Army and Navy IDIQs with minimal volume per vehicle.
Activity has accelerated modestly in 2025 and 2026 (five and seven awards respectively) after a period of lower baseline (two awards per year in 2020–2022), though the dollar magnitude per award remains small—typically $9,000 to $72,000 on recent purchase orders. Two awards carrying $207 thousand combined potential value complete in the next twenty-four months. The vendor subcontracts on boiler preventive maintenance services to Emcor Government Services under a Federal Bureau of Investigations facilities engineering contract at the Central Records Complex in Winchester, Virginia (base year and option year one, both 2025). The award portfolio concentrates in NAICS 541110 (Plumbing, Heating, and Air-Conditioning Contractors — 111 awards) and PSC codes for boiler maintenance and industrial boilers (52 awards combined), indicating a narrow, repeatable service model focused on federal facility infrastructure rather than new-construction or broad mechanical contracting.
