What McClure Engineering does
McClure Engineering is a privately held mechanical and electrical consulting engineering firm headquartered in St. Louis, Missouri, founded in 1953 and operating regionally in the Midwest United States with 101-250 employees. The firm delivers building systems engineering services across four core disciplines — mechanical, electrical, plumbing, and fire protection — supplemented by six specialty practices: lighting design, commissioning, acoustics, short circuit coordination studies, audio-visual/data and security systems, and theater systems design.
The firm's technical work is grounded in established engineering simulation tools, including SoundPlan for environmental noise and acoustic modeling and IES Virtual Environment 2017 for building energy simulation that accounts for conductive, convective, and radiant heat transfer. Notable proprietary delivery capabilities include custom audience blower system design for outdoor theaters (e.g., a 12-fan mixed-flow jet diffuser array delivering 150,000+ CFM at the MUNY) and integrated theatrical systems combining DMX/RDM lighting control with architectural lighting and AV. The company serves nine vertical segments — colleges and universities, K-12, healthcare, cultural institutions, government, commercial campus, critical facilities, food and pharma, and industrial — with a client roster spanning institutions such as Washington University in St. Louis, the MUNY, St. Louis Art Museum, Ritz-Carlton, Missouri Botanical Garden, and Wells Fargo.
McClure operates a project-based professional services revenue model, billing on fixed fees or time-and-materials depending on scope. Go-to-market is sales-led and relationship-based, with work sourced through direct engagement with building owners, architect specifications (e.g., HOK, H3 Studio, The Johnson Studio, Powers Bowersox Associates), general contractor partnerships, and repeat institutional clients. A core commercial relationship with Ameren Missouri's BizSavers program positions the firm as a preferred vendor for utility-incentivized energy efficiency projects, having helped clients earn documented incentives exceeding $300,000 across the Principia Simon Fieldhouse and St. Louis Art Museum projects. Marketing relies on thought leadership articles in industry publications, an active LinkedIn presence, and sustained employer-brand recognition (13 consecutive years on the St. Louis Post-Dispatch Top Workplaces list).
