Mr. Lam participated in 5 toll bridge seismic retrofit contracts which resulted in significant advancement in the state-of-practice in geotechnical engineering for design of major long-span bridges. Mr. Lam authored the Foundation Design Section of ATC-32 and the FHWA Guidelines on "Seismic Design of Highway Bridge Foundations". He has lectured in many states on FHWA workshops on seismic design of bridge foundations. He is also leading the effort, in two NCEER/FHWA contracts to upgrade seismic design and retrofit guidelines for bridges. Prior to forming Earth Mechanics, Inc., he worked almost exclusively on design of large foundation systems for offshore structures and gained a reputation within the offshore industry as a soil-structure-interaction and foundation design expert, especially on seismic issues.

Bridges Retrofit and Design, Statewide: Led the geotechnical team for the Carquinez, Richmond-San Rafael approaches, Vincent Thomas and Coronado bridge seismic retrofit contracts. Involved with the rebuilding of the collapsed I-10 bridges following the Northridge earthquake

New Oakland-Bay Bridge, East Span: Leading the effort to integrate specialized geologic, geophysics, rock mechanics, ground motion and dynamic response techniques in the design of the new Bay Bridge, east span.

Existing West Span Bay Bridge-Bike Path Feasibility: Participating in a project to study the feasibility for modifying the existing west span of the Bay Bridge to include bike paths on the existing suspension bridge between the Yerba Buena Island and San Francisco. The prime designer is CH2M HILL on this project.

New Benicia-Martinez Bridge: Lead geotechnical engineer in the T.Y. Lin-CH2M HILL contract to design for the new Benicia-Martinez (a segmental concrete bridge) at the Benicia-Martinez Strait to increase existing traffic capacity.

Arizona State Wide Seismic Mapping: Lead geotechnical engineer and the scope included aerial survey, fault trenching, leading the GPI effort on compiling the statewide maps on geologic and highway systems and probabilistic seismic risk analysis modeling and development of acceleration coefficient maps.
