What Overaa Construction does
Overaa Construction (legal entity C. Overaa & Co.) is a fifth-generation, family-owned general contractor and self-performing builder founded in 1907 by Norwegian immigrant Carl Overaa in Richmond, California, where it remains headquartered (with a South Bay office in San Jose). The company provides preconstruction, general contracting, collaborative delivery (including design-build and progressive design-build), and sustainable design & construction services across Northern California, executing significant scopes — structural concrete, foundations, carpentry, and finish work — with its own in-house craft teams rather than full subcontracting. Self-performing capability at this scale is described as uncommon among large commercial contractors and forms the operational core of the business.
The company serves 12+ vertical markets including K-12 and higher education, healthcare (OSHPD-regulated), water and wastewater infrastructure, transportation and public safety (fire stations, transit, airports, parking structures), industrial and logistics, energy, commercial, housing, concrete and seismic retrofitting, and cultural facilities. Notable customers include UC Berkeley, Sutter Health, Salinas Valley Health, FedEx, Genentech, Brentwood Union School District, Department of Energy/LLNL, City of Tracy, and Bay Area airports — predominantly public agencies, healthcare systems, universities, and select private enterprises. Bonding capacity of $1B supports projects in the $20M-$200M+ range.
Revenue is generated through project-based professional services: competitive public bidding and negotiated design-build contracts. Approximately 70% of work is delivered through collaborative methods with strategic design partners including Kitchell and DLR Group. Subcontractor engagement is systematized through the Building Connected platform with TradeTapp prequalification. The company is privately held with no external investors, parent entities, or subsidiaries disclosed, and has delivered over $15B in cumulative California infrastructure across its 119-year history.
