About SOHA

SOHA Engineers is one of the leading structural engineering firms in California, with offices in San Francisco and Oakland, California. SOHA professionals are dedicated to implementing and maintaining a creative and cost-effective approach to project delivery and award-winning structural design in a team environment.
For nearly four decades, SOHA has been providing a full spectrum of services, including seismic design of new buildings and structures, seismic evaluation and rehabilitation of existing structures and bridges, historical renovation, shoring and underpinning design, seismic evaluation and reports, plan checking, and peer review. We have engineered some of the most significant projects in the Bay Area, including numerous projects at the San Francisco International Airport, the new Children’s Center at Yerba Buena Gardens in San Francisco, the Chabot Observatory and Science Center in Oakland, the new east span of the San Francisco-Oakland Bay Bridge, and the Sacramento River Bridge at Rio Vista.

Our main focus is to provide the highest level of service to ensure the delivery of a successful project. SOHA maintains an exemplary record for completing projects on time. Meeting budget and scheduling requirements are the direct result of our sustained project management, value engineering, cost control, and quality control efforts, all of which SOHA routinely employs through each phase of every project.

SOHA has special expertise in seismic design and rehabilitation of commercial, government, transportation, and institutional facilities (including schools, community centers, prisons, and office buildings) in accordance with the latest codes and regulations in California. We also have extensive experience as a prime consultant to lead multi-discipline consultant teams and to effectively plan, execute and manage complex, multi-faced projects under tight budgetary constraints and demanding schedules.

SOHA is a minority-owned business enterprise (and DBE Certified) dedicated to maintaining an integrated staff and providing equal opportunity for both minority and women employees. Our staff actively participates in community and professional organizations.
