What Gayner Engineers does

Gayner Engineers is a San Francisco-based mechanical, electrical, plumbing (MEP), fire protection, and high-performance building design consulting firm founded in 1941. The firm operates as a private, independently-held professional services company with 51-100 employees, certified as a Minority Business Enterprise (MBE) by the NMSDC and as a Small Business Enterprise (SBE) under NAICS. Its service portfolio spans eight core disciplines: mechanical, electrical, plumbing, fire protection, lighting, control systems, energy modeling, and commissioning services. The firm is MBE/SBE-certified and staffs only experienced engineers (3-15 years tenure required), supporting an in-house, human-deliverable consulting model with no software or AI product surface.

The firm's client base is concentrated in California's institutional market — principally Stanford University, the University of California system (Berkeley, Merced, Santa Cruz, UCSF), Lawrence Berkeley National Laboratory, Washington Hospital Healthcare System, SF General Hospital, and Genentech — with one out-of-state engagement (Oklahoma Medical Research Foundation). Projects are characterized by technical complexity: OSHPD 1 healthcare facilities with base-isolation seismic systems (e.g., Washington Hospital Morris Hyman Pavilion, $338M, 223,000 sq.ft.), LEED Gold-certified clean rooms and vivariums (LBNL Molecular Foundry, UCSF Cardiovascular Research Building with 35,000 sq.ft. vivarium), and fast-track biotech construction delivered via Integrated Project Delivery (Stanford Lucas Center, ChEM-H/IoN). Repeat engagement patterns at Stanford and UC institutions indicate deep, durable client relationships built over decades.

Gayner Engineers generates revenue exclusively through project-based professional services fees on MEP design and commissioning engagements, procured via RFP and direct relationship with enterprise and government clients across the western United States. Pricing is quote-based and project-specific, with no disclosed subscription, product, or licensing revenue. Go-to-market is enterprise field sales targeting institutions rather than marketing-driven demand generation. The firm maintains an active careers pipeline and full benefits package (100% employer-paid medical/dental/vision, 401(k) match, performance bonus), signaling ongoing capacity build. No acquisitions, partnerships, funding rounds, parent companies, or geographic diversification beyond one out-of-state project have been disclosed in the available material.
