United Group Services

What United Group Services does

United Group Services is a privately held, full-service industrial construction contractor founded in 1982 and headquartered in Louisville, Kentucky, with a regional office in Cincinnati, Ohio. The firm was founded as a process piping contractor and has expanded its service portfolio to encompass ASME "R," "U," and "PP" code work; design-assist via laser scanning and construction layout; segregated carbon and stainless steel fabrication including a sanitary clean room; commercial and industrial HVAC delivered through its IMECH subsidiary; structural steel; rigging and millwright; insulation and scaffolding; and ongoing plant maintenance. It serves 13 industrial verticals — air/gas separation, alternative fuels (notably renewable natural gas), automotive, chemical processing, consumer products, food and beverage, pharmaceutical/biotech, plastics, power generation, pulp and paper, refinery/petrochemical, steel and foundry, and data centers — for enterprise clients such as Nucor, Procter & Gamble, LG&E, AK Steel, Honda, and International Paper.

The company operates a mobile craft workforce across the continental United States (251–500 employees), augmented by wholly-owned subsidiaries that deepen its operating model: the Elite Welding Academy (founded 2007) supplies skilled welders to mitigate the industry trades shortage, IMECH handles HVAC, and Core Crew provides workforce solutions. United Group Services monetizes primarily through project-based professional services (competitive bids on multi-million-dollar industrial construction projects, often with high prefabrication content — 98% on the Okeechobee RNG facility) supplemented by recurring managed-service plant maintenance contracts. Long-tenured anchor relationships (20+ years with Nucor, since 1986 with Procter & Gamble) and recent executive hires (CHRO 2024, VP of Safety 2025, Director of Corporate Client Development 2023) suggest an active growth and professionalization phase.
