What the agency is buying and why it matters
The Architect of the Capitol is seeking information from contractors for a potential Single Award Task Order Contract (SATOC) for mechanical and HVAC construction work. This includes repairs, alterations, and renovations at facilities within the Capitol Complex in Washington, DC.
The planned contract could be valued up to $250 million over one base year and nine option years. This is a significant opportunity for firms specializing in mechanical and HVAC services, as it covers a broad range of potential projects, such as air handling modifications, recording studio ventilation, and building heating system replacements.
Key dates and what happens at the deadline
Your capabilities package must be submitted by August 7, 2026, at 5:00 PM Eastern Time. This is a Sources Sought announcement, not a request for proposal, so no contract will be awarded directly from this submission.
The agency expects to issue a formal solicitation around November or December 2026. Responding to this RFI helps the Architect of the Capitol understand the market and may inform the final solicitation.
Who this opportunity suits
This opportunity is best suited for firms with strong experience in mechanical and HVAC construction, repair, alteration, and renovation projects. The primary NAICS code for this procurement is 238220 (Plumbing, Heating, and Air-Conditioning Contractors).
However, individual task orders may also involve NAICS codes such as 236220 (Commercial and Institutional Building Construction), 237110 (Water and Sewer Line and Related Structures Construction), 238110 (Poured Concrete Foundation and Structure Contractor), and 238210 (Electrical Contractors and Other Wiring Installation Contractors). Firms with a broad construction capability that includes significant mechanical/HVAC expertise will find this relevant.
