Mark III Construction is going big in McClellan Park, locking in a combined manufacturing and office campus that will serve as its new Sacramento-area headquarters. The family-owned firm is taking over more than 300,000 square feet of industrial space and says the move will pull its prefabrication, MEP assembly and modular production lines under one roof to shorten field schedules and scale up factory-built components.
According to CoStar, the deal is a 10-year, seven-month lease covering about 320,000 square feet across four bays, with roughly 34,000 square feet of office space. In a separate company announcement, Mark III described the campus as a 340,000-square-foot advanced manufacturing facility with a 34,000-square-foot office component that will turn out finished modular pods, prefabricated MEP systems and componentized wall panels. The square footage tallies do not match exactly, but either way it is a major step up for the Sacramento-based firm.
Where the campus sits
The new headquarters is identified as Building 783 at 2031 Optisolar Lane in McClellan Park, a master-planned business park northeast of downtown Sacramento. McClellan Park highlights its rail, runway and freeway access along with incentive programs for tenants, a combination that has made the former air base a magnet for industrial users. Listings for 2031 Optisolar Lane on Showcase.com show large bay footprints, dozens of dock positions and hundreds of parking stalls, all features that line up neatly with Mark III’s fabrication and distribution needs. Brokers and property managers of record handled marketing and lease negotiations for the property.
What it means for construction
The move doubles down on industrialized construction, the strategy of designing and manufacturing big chunks of a building off site so crews can assemble faster in the field with less labor. “This move represents a key step in M3’s mission to lead the evolution of construction,” Mark III said in its announcement. Industry outlets that picked up the release note that the model can shorten schedules and improve quality on complex projects, according to coverage from Constructionowners.com.
Local roots and next steps
Mark III started in 1976 as a local electrical subcontractor and has grown over five decades into a firm that handles MEP construction, service and components, according to company history shared on Howickltd.com. CoStar reported that a firm move-in date was not disclosed, and brokers say the larger campus will give Mark III room to chase bigger, time-sensitive projects across the Western U.S., positioning the company to supply factory-built systems to a wider range of owners and contractors.
