Projects
Selected work, organized by structure type. More than 1,000 numbered engagements since 1989 — these are representative.
Cofferdams & Deep Excavation Support
Sheet pile and braced cofferdams — in water and on land — and the deep excavation support that makes major construction possible. This is the core of the practice.






Major Bridges
Temporary structures, bracing, jacking, and excavation support for bridge construction and seismic retrofit — including multiple engagements on the Golden Gate and Bay bridges.





Retaining & Soil Nail Walls
Permanent and temporary retaining systems — soldier pile, tieback, raker-supported, and soil nail walls.






Underpinning
Supporting existing structures during adjacent excavation — shoring, jacking piers, and underpinning pits.




Micropiles & Specialty Foundations
Micropile design and installation, plus specialty foundation work — including the JC Decaux kiosk program in San Francisco.




Seawalls & Coastal Protection
Sheet pile seawalls and coastal structures built to last — the Bolinas seawall has required zero maintenance since 2014.


LiDAR As-Built Documentation
High-precision LiDAR scanning (Leica RTC360, BLK2GO) grounds the engineering in field reality — accurate as-built data for design and construction.
