About ZFA

Firm Profile

about-heritageFor more than 40 years, ZFA Structural Engineers has collaborated with public and private clients to help build better structures and facilities throughout California. With a commitment to excellence, we offer our clients innovative and practical design solutions for their projects and we deliver a high standard of client care.  ZFA serves clients from our five offices in San Francisco, Sacramento, Santa Rosa, and Silicon Valley- and our newest start-up office in Napa.

We have a staff of 60 dedicated employees with 36 structural engineers and 9 Professional Engineers. The firm is staff-owned and is both a Federal licensed and a California State licensed Small Business Enterprise (SBE).

Sustainable design is an important part of ZFA’s philosophy. The firm currently includes 11 LEED™ Accredited Professionals and contributes to the Structural Engineers Association of Northern California (SEAONC) Sustainable Design Committee. In addition, ZFA engineers use alternative building methods, such as structural insulated panels (SIP) and the Insulated Concrete Form (ICF) wall system on several building types.

ZFA brings engineering expertise to many sectors including: high-end residential, correctional, commercial, civic, fire stations, schools, wineries, maintenance, and hospitality and healthcare. We also have extensive experience with historic structures and a seismic retrofit practice.

ZFA principals commit to each project through completion with a proactive management approach and allow for ample engineering time to ensure that structural solutions are thoughtful and appropriate.

Projects begin with a series of pre-design meetings to establish goals, set reasonable schedules, identify deliverables, and design appropriate solutions based upon client goals. The involvement by our principal staff creates a collaborative environment and minimizes end-of-design changes. Throughout project design, principals and staff are on-call to assist with all aspects of design coordination. We firmly believe that responsiveness and continual collaboration are important throughout the process to ensure the project meets all the needs and goals of our clients.
