What DuBois & King, Inc. does

DuBois & King, Inc. is a multidisciplinary civil engineering consulting firm headquartered in Randolph, Vermont, founded in 1962 and operating across the New England and broader Northeast United States. The firm delivers integrated planning, engineering, and construction-phase services through seven core service areas: Civil + Survey, Construction Phase Services, Environmental Services, MEP + S (Mechanical, Electrical, Plumbing + Structural), Planning Services, Transportation Services, and Water + Dams + Hydro. Its technology foundation centers on Building Information Modeling (BIM) for design communication and structural analysis tools covering steel, concrete, timber, and masonry, augmented by specialized capabilities in FERC Part 12D dam inspections, NEPA permitting, and wastewater process design.

The firm serves nine primary market verticals — Municipal, Federal, State, Healthcare, Education, Electric Utilities, Commercial, Agriculture, and Housing — with public-sector work (municipal infrastructure, federal/state projects) representing the dominant demand base alongside institutional clients in healthcare and education. Pricing is project-based and negotiated through public bidding processes for government work and direct engagement for private clients; specific fee structures are not publicly disclosed. D&K is 100% employee-owned through an Employee Stock Ownership Plan (ESOP), with all governance vested in an internal management team and Board of Directors composed exclusively of D&K professionals.

DuBois & King's go-to-market is relationship-driven professional services sales, supported by project case studies on its website, organic social media presence (LinkedIn, Facebook, Instagram), and community engagement. In May 2026, the firm acquired DeWolfe Engineering Associates for an undisclosed amount, signaling an M&A-led capacity expansion strategy alongside its organic service-line and vertical diversification. The firm employs 101-250 people and maintains long-tenured client relationships, including 25+ years with Gifford Health Care and decades with Central Vermont Medical Center.
