EME

Emcor Group, Inc.

A U.S. specialty contractor behind big electrical and mechanical projects—data centers, high-tech factories, and commercial buildings—plus ongoing maintenance, HVAC retrofits, and industrial work like refinery turnarounds and specialty welding. Its roots go back to 1966, when it started as the Jamaica Water Supply Company, a New York water utility that grew into the sprawling JWP Inc. before emerging from a 1990s restructuring under the name EMCOR—a brand hinting at electrical and mechanical construction.
