About
Founded in 1928 and backed by nearly a century of large-scale electrical contracting experience, Mass Electric Construction Co. (MEC) delivers heavy industrial, transportation, and power delivery projects across North America — including complex work in Honolulu, HI. As a Kiewit company and proud IBEW signatory, MEC brings integrated design, engineering, and construction teams to every engagement, offering facility managers and property owners a single accountable partner for the full project lifecycle. In Honolulu's demanding commercial and industrial market, MEC is positioned to execute power distribution upgrades, switchgear installation, panelboard replacements, and large-scale generator systems for industrial facilities, government campuses, institutional buildings, and healthcare complexes. Their proven capability in mission-critical shutdown and cutover sequencing — refined over decades of hospital and transit work — translates directly to occupied commercial facilities where power continuity is non-negotiable. MEC's power delivery division handles transmission, substation construction, and underground cable systems, making them a credible choice for utility-scale and on-site distribution infrastructure on Hawaii's unique grid environment. Their industrial electrical portfolio spans water treatment facilities, refineries, and heavy manufacturing — project types that demand rigorous NEC compliance, three-phase power expertise, and precision coordination with other trades. With a national footprint and the engineering depth of a century-old firm, MEC offers Honolulu facility managers and general contractors the rare combination of local execution capability and enterprise-grade project controls. For owners managing large institutional campuses, government facilities, or complex industrial sites in Hawaii, MEC represents a contractor equipped to handle both the scale and the technical complexity that most regional firms cannot match.
