About the company
Dubois & King Inc., a Vermont-based for-profit engineering and consulting firm, provides architectural and engineering design services, facility studies, and construction-phase support to federal agencies as a prime contractor (100% of recent awards), competing predominantly under total small business set-asides across a geographically concentrated New England footprint. The firm holds a $40 million GSA Public Buildings Service Region 1 multiple-award IDIQ (award date January 1, 2025, performance through June 30, 2030) and a $9.975 million Coast Guard District One architect-engineering IDIQ (award date October 25, 2022, completion October 24, 2026), both reserved for small businesses and anchoring most of its federal work in the Northeast.
Dubois & King's customer concentration is fragmented across civilian infrastructure and health agencies, with the General Services Administration Public Buildings Service Region 1 dominating by potential value ($40.3 million across 5 awards) and the Department of Veterans Affairs Veterans Integrated Service Network 1 placing the most awards by count (33 awards, $24.6 million combined potential value). The Army Corps of Engineers accounts for 54 awards but the portfolio summary does not quantify that volume's potential value. Across the top five customers by potential value (GSA, VA, Coast Guard, USDA Forest Service R9, and Interior Fish and Wildlife), these agencies represent 88% of the combined potential value. Recent representative work includes a $60,000 delivery order from GSA for design services at the Canaan Land Port of Entry in Canaan, Vermont (August 19, 2026), a $75,928.82 Coast Guard delivery order for a water treatment system study at USCG Station Jonesport, Maine (June 12, 2026), a $236,928.98 Coast Guard order for boat maintenance facility design in Woods Hole, Massachusetts (September 10, 2024), and a $445,238.11 VA emergency power distribution contract in Manchester, New Hampshire (May 26, 2022).
The vendor's work distribution across parent vehicles reflects deep roots in federal A/E IDIQs: five Army Corps of Engineers IDIQs (AG1644C060001, DACW5101D0012, DACW3399D0001, DACW5197D0023, and unnamed vehicles) carry the plurality of task orders, with the GSA Region 1 IDIQ and Coast Guard District One IDIQ as the primary civilian vehicles. Portfolio composition skews heavily toward engineering services (160 awards) and architectural services (11 awards) under PSC codes for general A/E and A/E landscaping and design work. Activity has contracted in recent years (seven awards in 2022 declining to three in 2024, then recovering to five in both 2025 and 2026), with only seven awards reaching ultimate completion in the next twenty-four months and facing recompete (combined potential value $682 thousand), creating limited near-term recompete exposure. The firm operates a minimal subcontract footprint (one sub-award recorded as of the source date).
