Mark III Construction
Who we are:
Mark III is a full-service construction company comprised of three complementary business units: M3 MEP, M3 Service, and M3 Components. We support projects from initial concept through long-term maintenance, with specialized expertise in healthcare, higher education, industrial, life science, and technology markets.
Our integrated, big-picture approach allows us to self-perform electrical, HVAC, plumbing, process piping, prefabrication, and MEP design. By consolidating these services under one organization, clients benefit from reduced profit layers, minimized scope gaps, and simplified project schedules—working with a single, accountable partner rather than multiple consultants and subcontractors.
Headquartered in Sacramento, California, Mark III operates throughout California and Nevada. Our state-of-the-art manufacturing facility serves as a centralized hub supporting five core trades: HVAC, mechanical piping, plumbing, electrical, and metal-stud framing. To support our continued growth, we will be relocating from our current combined 62,000 square feet of office and operational space to a new 340,000-square-foot headquarters at 2031 Optisolar Lane, with the move planned for completion by the end of Q2 2026.
