What United Engineers & Constructors does
United Engineers & Constructors (United) is a private, US-incorporated engineering, procurement, and construction (EPC) firm founded in 1905 and headquartered in Mt. Laurel, New Jersey, with regional offices in Charlotte (NC), Milford (MA), Schaumburg (IL), and Kincardine (Ontario). The company delivers integrated project solutions across the full power-generation lifecycle—planning, design, engineering, procurement, construction, maintenance, modification, and decommissioning—for nuclear utilities, conventional generation operators, and distributed energy resource developers. Its core offerings are organized around three service categories: Nuclear Services (major component replacement, SMR support, outage services, and decommissioning), Power Generation Services (combined-cycle gas, coal environmental retrofits, water/wastewater), and Distributed Energy Resources Services (battery storage, solar, hydrogen, EV charging, microgrids). The company maintains specialized capabilities through its wholly-owned subsidiary Imperia Engineering Partners, which operates a materials engineering laboratory for failure analysis and corrosion assessment.
United generates revenue primarily through professional services contracts—project-based EPC engagements, master services agreements, and long-term engineer-of-choice (EOC) alliances—priced via custom quotes rather than published tiers. Customer relationships are concentrated among large North American investor-owned utilities and nuclear fleet operators, including Bruce Power, Duke Energy, DTE Energy, Tennessee Valley Authority, Luminant/Vistra, Southern Company, Arizona Public Service, We Energies, Alliant Energy, Southern California Edison, and PSE&G. Strategic nuclear component-replacement work is delivered through consortium-style joint ventures: SGRT (with Framatome and Aecon) and Shoreline Power (with AtkinsRéalis and Aecon) on Bruce Power units 3-8, and the Steam Generating Team with Framatome for TVA Watts Bar Unit 2. In January 2025, Aecon Group Inc. acquired United from affiliates of CriticalPoint Capital to scale its nuclear and power-generation footprint across North America.
