Full-service MEP and prefab contractor across California and Nevada
Mark III operates three integrated business units—MEP, Service, and Components—executing mechanical, electrical, plumbing, and prefabrication work across healthcare, e-commerce, food/beverage, commercial, and education. The tech stack is heavy on Autodesk (Revit, BIM 360), Procore, and Trimble, with active hiring concentrated in construction trades rather than software engineering—a profile consistent with a contractor scaling execution and on-site delivery rather than pursuing digital transformation.
Mark III Construction is a full-service contractor headquartered in Sacramento, California, and founded in 1976.

Licensed across California and Nevada, Mark III serves healthcare, commercial, e-commerce, food/beverage, and education clients. Current initiatives include relocation to new headquarters, development of prefabrication methods, and a shift toward proactive maintenance—alongside active pressure to simplify project schedules and reduce profit layers.
