Tuan and Robinson Structural Engineers

What Tuan and Robinson Structural Engineers does

Tuan and Robinson Structural Engineers, Inc. (TRSE) is a privately held structural engineering consulting firm founded in 1999 by Eugene Tuan and Alan Robinson and headquartered at 444 Spear Street in San Francisco, California. The firm delivers structural engineering services for new building design, seismic retrofit and rehabilitation, historic renovation, deep excavation shoring, building underpinning, specialty retaining walls, and temporary construction support structures across Northern California. Its work spans wood, steel, concrete, and masonry construction, with documented projects ranging from minor residential additions to a 17-story high-rise seismic retrofit in downtown San Francisco, and including complex shoring engagements adjacent to operating hospitals, university research facilities, and BART transit infrastructure.

The firm's underlying technology stack is conventional for a small structural consultancy: industry-standard AutoCAD and Revit for drafting and documentation, paired with structural calculations and computer analysis. TRSE's service catalog is organized into seven discrete offerings: core structural engineering consulting, seismic retrofit design, excavation shoring design, underpinning design, temporary construction support structures, specialty retaining wall design, and ancillary consultation services including Probable Maximum Loss (PML) reports, peer review, and plan check. The firm holds Disadvantaged Business Enterprise (DBE), San Francisco Small Business Enterprise, and California Small Business certifications, which provide procurement advantages on publicly funded and OSHPD-regulated projects.

TRSE operates as a project-based professional services consultancy, billing clients through quote-driven fees tied to project scope and complexity rather than disclosed hourly rates. Its customer base spans architectural firms, contractors, developers, and government and institutional clients including UC Davis, Stanford, Marin General Hospital, El Camino Hospital, Lawrence Berkeley National Laboratory, the San Francisco Public Utilities Commission, the Presidio Trust, and the National Park Service. The firm is actively recruiting a Project Manager and Entry Level Staff Engineer as of 2025, consistent with its stated 25-year operating history and headcount in the 15-20 range.
