What STRUCTUS does

STRUCTUS, Inc. is a privately held consulting structural engineering firm headquartered in San Francisco, founded in 1987. The firm provides structural analysis, design, seismic evaluation, and retrofit services for buildings and special infrastructure, with particular technical differentiation in base isolation systems and viscous damper energy dissipation technologies used in seismic protection. Its service portfolio spans new building design, transportation structures, water and wastewater facilities, piers and waterfront structures, seismic retrofit and historic preservation, peer review and plan checking, and structural special inspection.

The firm operates almost exclusively with public-sector clients across the San Francisco Bay Area, including the City and County of San Francisco, San Francisco Unified School District, BART, SFMTA, San Francisco Public Utilities Commission, San Francisco International Airport, the Port of San Francisco, and San Francisco General Hospital. Notable landmark assignments include the San Francisco Opera House Seismic Retrofit and the Kagoshima Air Terminal Seismic Retrofit in Japan. STRUCTUS holds CUCP-certified DBE, San Francisco CMD-certified small LBE, and OSHPD plan check certifications that grant access to set-aside and regulated public contracts.

The business model is professional services on a project-fee basis, with work secured through direct engagement, joint ventures with peer firms (Degenkolb Engineers, Forell/Elsesser Engineers, Middlebrook + Louie), and government procurement processes. The firm employs 11–50 staff led by five principals with combined experience exceeding 150 years, including a Ph.D.-credentialed earthquake engineering specialist. Revenue is not publicly disclosed and the company has not raised external institutional capital.

Broad incumbents

• Simpson Gumpertz & Heger (SGH): National structural engineering consulting firm with deep expertise in structural analysis, retrofit, and failure investigation. Competes for complex seismic and institutional work but operates at much larger scale and broader geography.
• Arup: Global engineering consultancy with a leading seismic and structural engineering practice and a San Francisco office. Competes for high-profile seismic retrofits and public-sector work; broader multi-discipline capability differentiates it from STRUCTUS.
• KPFF Consulting Engineers: Large U.S. structural and civil engineering consulting firm with a strong California presence and seismic practice. Competes for similar public-sector and institutional RFPs but offers broader multi-discipline services and significantly more capacity.
• Wiss, Janney, Elstner Associates (WJE): National engineering firm specializing in structural investigation, repair, and rehabilitation of existing and historic structures. Highly comparable in seismic retrofit and preservation work, but larger and more diversified geographically.

Direct peers

• Forell/Elsesser Engineers: San Francisco–based structural engineering consulting firm with a strong seismic retrofit and historic preservation practice. Directly comparable in service mix, geography, and seismic expertise, and an existing JV partner of STRUCTUS.
• Degenkolb Engineers: San Francisco structural engineering firm nationally recognized for seismic design and earthquake engineering. Comparable in target clients (hospitals, schools, public infrastructure), seismic niche, and JV partnership pattern with STRUCTUS.
• Holmes Structures: San Francisco structural engineering firm with a strong seismic and new-building design practice. Direct peer in scale, geography, and client mix (developers, institutions, public agencies) competing for similar regional RFPs.
• Tipping Structural Engineers: Berkeley-based structural engineering firm recognized for seismic innovation, performance-based design, and mass timber. Highly comparable technical niche, Bay Area geography, and emphasis on advanced seismic systems.
• Middlebrook + Louie: San Francisco structural engineering firm serving civic, educational, and mixed-use developments. Comparable in service mix, Bay Area geography, and small-firm positioning; STRUCTUS's listed JV partner on projects such as the Fillmore Heritage Center.

Regional players

• Buehler & Buehler Structural Engineers: California structural engineering firm with a public-sector and institutional practice. Comparable in service offering and California focus but more Sacramento-centric; competes indirectly for similar public-infrastructure scopes.
