Blach Construction Company

What Blach Construction Company does

Blach Construction Company is a privately held California general contractor founded in 1970 by Michael S. Blach and currently led by Chairman Mike Blach and President Dan Rogers (since 2017). The firm provides commercial building and construction management services through five integrated disciplines: Design-Build, Preconstruction, Virtual Design & Construction (VDC), Construction, and Prefabrication. It serves K-12 and higher education, housing (affordable, market-rate, senior, student), institutional (civic, cultural, healthcare, non-profit), mixed-use, and workplace (office, technology/lab) markets across California via three regional offices—San Jose (Bay Area headquarters), Monterey (Central Coast), and Orange County (Southern California, opened 2021).

The company's core technical differentiator is the Folia prefabricated building system, a proprietary turnkey solution developed jointly with Quattrocchi Kwok Architects (QKA) and GPLA structural engineers. Folia uses Division of State Architect (DSA) pre-checked designs to compress approval and delivery timelines on K-12 classroom projects. Supporting capabilities include an in-house VDC team using laser scanning, robotic layout, and BIM modeling; a dedicated in-house MEP coordination team; and structured employee development programs (Blach University, PE Boot Camp, Beyond Boot Camp). Noteworthy project outcomes include a 40,000 sq.ft. Folia classroom building at Cupertino High School delivered in nine months and 3.8 million hours worked without a lost workday over the decade ending 2020.

Blach generates revenue primarily through project-based general contracting on a competitive-bid and design-build basis with public agencies (school districts, municipalities) and private developers. Pricing is negotiated per project and not publicly disclosed. Projects are pursued through a regional enterprise field-sales model with dedicated business development directors and project executives; recent joint-venture activity (e.g., the 794,000 sq.ft. Gateway at Millbrae Station with Cahill Contractors) signals growing capacity for larger mixed-use pursuits. The firm is consistently ranked among California's top contractors by Engineering News-Record and has won multiple AGC of California Construction Safety Excellence Awards.
