Nibbi Brothers General Contractors

What Nibbi Brothers General Contractors does

Nibbi Brothers General Contractors is a privately held, third-generation family-owned general contractor founded in 1950 and headquartered in San Francisco, operating a secondary office in Oakland. The firm builds complex urban construction projects across the San Francisco Bay Area, serving developers, public agencies, nonprofit affordable housing organizations, healthcare systems, and educational institutions. Its project portfolio spans multi-family and mixed-use residential (market-rate and affordable), commercial and civic buildings, education facilities, seismic and historic retrofits, waterfront work, and community-based developments. The majority of revenue, disclosed as exceeding $450 million annually, is generated through negotiated contracts with repeat clients rather than competitive bidding.

The company's service stack is structured around four core capabilities: Preconstruction & Estimating, Virtual Design Construction (VDC) and Building Information Modeling (BIM), full Construction Services using collaborative delivery models (Progressive Design-Build, IPD, Lean), and a Quality Assurance/Quality Control function. It has two wholly-owned self-perform divisions—Nibbi Concrete (formed 2005) for structural concrete work and Nibbi SPS (formed 2020) for production framing and carpentry employing over 100 skilled field workers—and a NibbiPrefab division for modular and prefabricated construction. Technology integrations include BIM/VDC 3D design environments, OpenSpace for daily site documentation, TradeTapp by BuildingConnected for subcontractor prequalification, and the Firmus AI tool used since 2022 for constructability reviews on more than 15 projects.

Nibbi is led by Bob Nibbi (President and CEO, Stanford-trained construction engineer, third generation) and Mike Nibbi (Director of Strategy and Culture), with Larry Nibbi serving as Chairman. Operations are run by COO Greg Narvick (with Nibbi since 1998, promoted to COO in 2020) and CFO Raj Choudhary (with Nibbi since 1994). The company markets through direct enterprise relationships, a community engagement and workforce development function, and earned media, with notable clients including Kaiser Permanente, Equity Residential, EAH Housing, Mercy Housing California, TNDC, Satellite Affordable Housing Associates, and the Native American Health Center. Its safety program has earned continuous Construction Employers Association Excellence in Safety awards since 2003 and CAL/OSHA VPP Construction recognition.
