What Bay City Mechanical does
Bay City Mechanical is a privately held, California-based design-build mechanical engineering firm founded in 1991 by Helge Theiss-Nyland. The company designs, installs, and services HVAC, plumbing and hydronic piping, architectural sheet metal, and building automation systems for commercial, institutional, and high-rise residential construction projects, operating from four offices across California (Richmond headquarters, Sacramento, San Francisco, and Vista) and serving clients statewide. Core service lines are Design Engineering & BIM, Mechanical HVAC, Architectural Sheet Metal, Plumbing & Hydronic Piping, Building Automation, and BCM Service (preventive maintenance and repair).
The technical stack centers on Building Information Modeling (BIM) for coordinated 3D design, in-house sheet metal fabrication, hydronic piping systems including certified City Multi-Zone installations, and building automation controls integration. As a signatory to Sheet Metal Workers' Local 104 Union, BCM draws on a unionized skilled-trade workforce. Its demonstrated portfolio spans LEED Platinum and Gold projects (Urban School, 855 Brannan, EmeryStation West, 1000 Gateway Blvd, 520 Almanor) and high-visibility institutional clients including UC Berkeley, UC San Diego, Hyatt Regency San Francisco, El Camino Women's Health Hospital, Docker, NASDAQ Entrepreneurial Center, VacaValley Medical, Brown & Toland, and Hillsdale Mall.
BCM's business model combines project-based design-build revenue (fixed-price contracts secured through competitive bidding and relationship-based development with general contractors, owners, architects, and engineers) with recurring service and maintenance contracts through the BCM Service sub-brand. Pricing is custom per project scope; no public pricing exists. The company remains founder-controlled with no disclosed external investors or parent company, and an executive team led by CEO/Founder Helge Theiss-Nyland, President Chad Olson, CFO Emmanuel Akuaku, and COO Bobbie Amos.
