McClure Company

What McClure Company does

McClure Company is a privately held, full-service mechanical construction, engineering, and energy services firm headquartered in Harrisburg, Pennsylvania, with five additional offices across Pennsylvania (State College, Warrendale/Pittsburgh, Wilkes-Barre, Williamsport) and Westminster, Maryland. Founded in 1953, the company employs 251-500 people and operates as a wholly owned subsidiary of Sojitz Corporation, a Japanese conglomerate, integrated into Sojitz's Energy Solutions segment under the KATI growth model. The company designs, installs, fabricates, and services mechanical systems — HVAC, plumbing, boilers, chillers, sheet metal, high-purity and process piping, modular skid assemblies, and pressure vessels — across K-12 education, higher education, healthcare, government, industrial, oil & gas, pharmaceutical, and power generation sectors.

The underlying technology stack centers on Building Information Modeling (BIM) and Virtual Design & Construction (VDC), supported by AutoCAD MEP, AutoCAD MEP REVIT, Navis Works Manage, Fabrication CAD MEP, Autodesk Construction Cloud, Stratus Fabrication, FARO 3D scanner, Trimble Robotic Total Station, and Resolve VR Model Review. A 22,000 sq. ft. semi-automated fabrication shop in Harrisburg produces piping assemblies from 1/4\" to 78\" in diameter. The company holds ASME \"S,\" \"U,\" and \"R\" code stamps for pressure vessels and is NAESCO-accredited as an Energy Service Company, offering performance contracting (ESPC/GESA), guaranteed energy savings agreements, energy audits, commissioning, and renewable energy integration (solar, geothermal, biomass).

Revenue is generated through four streams: project-based mechanical construction (one-time), Energy Savings Performance Contracting and ESCO services (managed services), maintenance and 24/7 service agreements (recurring), and energy audits/engineering consulting (professional services). Pricing is project-specific and quote-based; multi-year contracts are common. Go-to-market is direct enterprise field sales across six regional offices, augmented by cooperative purchasing program registrations (COSTARS, TIPS, Sourcewell, Equalis Group, Keystone Purchasing Network, GSA) that enable public-sector procurement without competitive bidding. Notable project execution includes over $35M for Penn State University, $55.6M for Penn State Health Lancaster Medical Center, $43M for Penn State Health Hampden Medical Center, $33.7M for Mifflin County School District's solar array, $31M+ for Mount Nittany Medical Center, and cumulative $180M in measured and verified energy savings delivered to clients.
