About
Operating since 1906, Electric Construction Company is one of South Dakota's largest and most experienced commercial electrical contractors, routinely fielding a workforce of 70 or more licensed electricians on projects across Sioux Falls and the surrounding region. That scale and longevity matter to facility managers and property owners who need a contractor capable of handling complex, fast-track builds without compromising schedule or code compliance. The company's core portfolio spans large commercial and industrial projects: hospitals, medical clinics, office buildings, retail stores, schools and universities, government facilities, correctional facilities, and industrial plants. Whether the scope involves power distribution upgrades, switchgear installation, panelboard replacement, or lighting system retrofits, Electric Construction's journeyman electricians train beyond state license minimums, and apprentices complete a full five-year nationally registered program — giving facility teams confidence in both quality and safety on every engagement. Beyond core electrical construction, Electric Construction maintains a dedicated service division specializing in high-voltage work, voice and data cabling, and fiber optic infrastructure, making them a single-source option for facility managers coordinating electrical and low-voltage scope on the same project. Their design-build capability adds further value for owners and general contractors who want early contractor involvement to optimize constructability and cost. New construction, complete building remodels, electrical upgrades, and ongoing service work are all in scope. With over a century of continuous operation in Sioux Falls, Electric Construction Company brings institutional knowledge of local utility requirements, NEC compliance expectations, and the specific demands of healthcare, institutional, and government facilities that newer contractors simply cannot match. Facility managers managing multi-building campuses or complex occupied renovations in the Sioux Falls metro will find a contractor with the workforce depth and project management discipline to deliver.
