Our professional staff has worked on many small and large projects. A few of the projects that our staff has been involved are listed below:

RESIDENTIAL PROJECTS

Miles Drive, Santa Clara 
Client: Property Owner
Project Description: The project consisted of foundation repair of an existing two-story wood-framed building at the subject site. The foundation of the house has experienced excessive settlement and cracks were visible.

A Geotechnical study performed consisting of drilling four holes, obtaining soil samples and performing geotechnical laboratory testing on the collected soil samples. In a geotechnical report, both the cause of cracking and settlement and several mitigation options were discussed. Recommendations for the most cost-effective option was also provided.

Belbrook Way, Atherton 
Client: Property Owner
Project Description: The project consisted of an addition to the existing building.

A Geotechnical study performed consisting of drilling four holes, obtaining soil samples and performing geotechnical laboratory testing on the collected soil samples. In a geotechnical report, several foundation options were discussed and recommendations for the most cost-effective option was provided.

Pullman Avenue, Belmont
Client: Property Owner
Project Description: The project consisted of retaining wall repair at the subject site. The existing retaining wall  has experienced excessive deformation.

A Geotechnical study performed consisting of drilling three holes, obtaining soil samples and performing geotechnical laboratory testing on the collected soil samples. In a geotechnical report several repair options were discussed and recommendations for the most cost-effective option was also provided.

College Avenue, Palo Alto 
Client: Property Owner
Project Description: The project consisted of backfilling of an existing excavation in a basement and provide drainage recommendations.

A site visit was performed and a recommendation letter consists of several feasible backfill methods was provided.

Yosemite Avenue, Mantica
Client: Property Owner
Project Description: The project consisted of construction of a one-story office building at the subject site. 

A Geotechnical study performed consisting of drilling three holes, obtaining soil samples and performing geotechnical laboratory testing on the collected soil samples. In a geotechnical report several foundation options were discussed and recommendations for the most cost-effective option was also provided.

PUBLIC PROJECTS

Sunol Valley Water Treatment Plant Improvements Project 
Client: San Francisco Public Utilities Commission (SFPUC)
Project Description: Design a new water treatment plant and 346-foot diameter treated water storage reservoir. The project was one of the largest and most complex undertaken by SFPUC in several years.

Geotechnical studies performed addressing issues related to Faulting, Groundwater, Earthwork requirements, Slope stability, Liquefaction, Corrosion potential of pipes, Pavement design, and Foundation design.

Walnut Creek-San Ramon Valley Tunnel/Pipeline
Client: East Bay Municipal Utility District
Project Description: As part of EBMUD's San Ramon Valley Water Master Plan, which extends from Walnut Creek to Stone Valley Road in Danville, a new 69-inch diameter water pipeline is planned to extend between Danville Pumping Plant and an existing 84-inch diameter pipeline under North California Boulevard near the Walnut Creek BART station. 


A final geotechnical study was performed to develop design recommendations.  The final report included geologic and geotechnical conclusions and recommendations related to tunnel design, trench design, geoseismic hazards, seismic design parameters, earthwork, and dewatering. The conclusions and recommendations presented in the report were based on the extensive drilling and laboratory testing performed specifically for this project during the study to provide refinement for geotechnical conclusions and recommendations.
