About Mark III Construction
Mark III Construction exists to lead the evolution of construction and expose the world to a new way to build. Founded in 1976, the company has grown from a single-trade electrical contractor into a full-service MEP (Mechanical, Electrical, and Plumbing) construction powerhouse serving California and Nevada. Through their "Power of One" approach, Mark III self-performs electrical, HVAC, plumbing, process piping, underground utilities, prefabrication, and MEP design - eliminating profit layers, scope gaps, and scheduling complexity that plague traditional multi-subcontractor projects.
Headquartered in Sacramento with offices in Sparks, Nevada, Mark III operates three complementary business units: M3 MEP for construction projects, M3 Service for 24/7 emergency and preventative maintenance, and M3 Components for manufacturing and industrialized construction solutions. Their state-of-the-art 62,000-square-foot manufacturing facility serves as a centralized hub supporting five core trades, with plans to relocate to a new 340,000-square-foot headquarters at McClellan Park by Q2 2026. The company specializes in healthcare, higher education, industrial, life science, and technology markets, and was named ENR California's Specialty Contractor of the Year in 2019.
