McClure Engineering is an employee-owned mechanical, electrical, plumbing and fire protection engineering firm at 1000 Clark Avenue in downtown St. Louis. Its site claims more than 100 employees, over 30 professional engineers, registration in 30-plus states and upward of 7,000 completed projects, and it cites more than 70 years of experience without giving a founding year. Specialty groups cover lighting, commissioning, acoustics, audiovisual and security, and theater systems. Clients include universities, K-12 districts, hospitals, cultural institutions, food and pharmaceutical plants and critical facilities. On the Powell Hall Renovation and Expansion in St. Louis, the St. Louis Symphony Orchestra’s team list names McClure as MEP and fire protection engineer.
Nine markets, and why the specialty groups matter
McClure Engineering sorts its work by market before it sorts it by discipline, and the nine categories it names tell you what kind of buildings it is set up for: colleges and universities, food and pharmaceutical, commercial campus, critical facilities, cultural institutions, K-12 education, healthcare, industrial and government. Those are mostly campus and institutional owners with long equipment lifecycles, which is a different business from one-off commercial fit-out.
The four core services — mechanical, electrical, plumbing and fire protection — are the expected ones. The specialty list is where this firm differentiates, and it is longer than most MEP practices publish: lighting, commissioning, acoustics, short circuit coordination studies, audio-visual/data and security, and theatre systems. Short circuit coordination studies in particular are an electrical-safety deliverable that most owners have to procure separately. Theatre systems alongside acoustics explains how a mechanical and electrical firm ends up on concert hall work.
The published statistics, and what they do and don’t say
The about page carries a stats block worth reading precisely. More than 70 years of experience. 100% employee owned. More than 7,000 total projects. More than 900 total clients. More than 100 employees and counting. More than 30 professional engineers. More than ten LEED accredited professionals, plus a count of states the firm is registered in.
Note that “70+ years of experience” is not a founding year, and the firm does not publish one, so this listing records none. The 100-plus headcount places it in the 51 to 200 band, and the LEED accreditation count supports the sustainability positioning the firm also maintains as a dedicated page.
The practice is described in terms of stewardship of the built and natural environment, with the stated aim of turning complex engineering problems into solutions that are reliable and straightforward to operate and maintain — a bias toward serviceability that fits the campus and institutional client base. Three named values follow: ownership, which the firm calls its hallmark and frames as accountability for every task; partnerships, built on valuing client input to reduce risk; and integrity.
The office is at 1000 Clark Avenue in downtown St. Louis, on 314-645-6232, and the contact page goes to the trouble of explaining visitor parking at the rear of the building on Spruce Street between 10th and 11th, with a voucher available from reception. The firm publishes articles and technical papers, runs an active careers page seeking mechanical and electrical engineers and support staff, and links Facebook, Instagram, LinkedIn and a YouTube channel from its own site.
