What Intermech does

Intermech, Inc. is a specialty mechanical and industrial contracting company headquartered in Richland, Washington, with additional offices in Idaho Falls and Meridian, Idaho. The company operates as a wholly-owned subsidiary of EMCOR Group, Inc. (NYSE: EME), one of 80+ operating companies within EMCOR's portfolio. Founded in the early 1980s to support commercial nuclear power plant construction, Intermech has built a service portfolio spanning HVAC construction, process piping, building concrete, scaffolding, and specialty fabrication and erection, along with a service and maintenance division (American Chiller Service, or ACS) acquired in 2024 to extend HVAC service capabilities throughout Idaho.

The company's technical platform is anchored by a Quality Assurance Program established around ASME NQA-1 in the early 1980s, regularly audited by commercial nuclear customers and government nuclear site operators. Intermech holds multiple ASME code stamps ('U', 'PP', National Board 'R'), complies with 10 CFR 50 Appendix B, 10 CFR 830, NRC Regulatory Guide 1.28 Rev 4, and DOE O 414.1D, and is qualified for NUPIC-audited sites. Capabilities include in-house BIM modeling for constructability reviews, a modern pipe fabrication facility, and both field and shop fabrication services. Welder qualifications span ASME BPVC Section IX and ASNT SNT-TC-1A non-destructive examination standards.

Intermech generates revenue through project-based contracting delivered directly to enterprise and government clients in heavy industrial, energy, life sciences, and government (DOE/DOD) segments. The company operates as either a prime contractor or specialty subcontractor depending on client needs, providing pre-construction, project management, fabrication, installation, and ongoing service and maintenance. Named customers span Washington River Protection Services, Central Plateau Cleanup Company, Energy Northwest, Framatome, Idaho National Laboratory, Chobani, JR Simplot, and Idaho Falls Power, with additional confidential data center work. Pricing is quote-based and tailored to individual project requirements, with no publicly disclosed pricing, revenue, or backlog.
