About
Founded in Boston in 1928 and active across North America for nearly a century, Mass. Electric Construction Co. (MEC) is a heavy-industrial and infrastructure-grade electrical contractor with the engineering depth to execute projects most firms cannot staff or sequence. Facility managers and property owners overseeing complex, high-criticality assets — industrial plants, water treatment facilities, power generation sites, and large institutional campuses — will find MEC operating at a scale and technical tier well above typical commercial electrical contractors. As a Kiewit Infrastructure company and IBEW-signatory firm, MEC brings integrated design, engineering, and construction teams to every engagement, delivering greater cost and schedule certainty on power distribution, switchgear, panelboard and breaker installations, backup generator systems, and large-scale lighting retrofits. Their industrial electrical division handles heavy facilities including refineries, water treatment plants, and power generation infrastructure — making them a strong fit for Boston-area industrial and manufacturing campuses requiring multi-discipline coordination. MEC's demonstrated capability in strict shutdown and cutover execution — honed through decades of hospital and transit work in Greater Boston — translates directly to facility managers who cannot tolerate unplanned downtime during electrical upgrades or switchgear replacements. Their low-voltage and data infrastructure experience, developed through landmark projects like the Central Artery/Tunnel, positions them well for institutional and government facilities undergoing technology-driven electrical system modernization. With project reach spanning Boston and major metros across North America, MEC is particularly well-suited for multi-site owners and large general contractors managing federal, municipal, healthcare, or industrial portfolios that demand contractor financial stability, union labor, and engineering resources under one roof.
