The master developer implemented several geotechnical mitigation measures to address the presence of loose sand fill, which is susceptible to cyclic densification and liquefaction, as well as the presence of highly compressible clay (Bay Mud) underlying the site. The mitigation measures include dynamic compaction to densify the sand fill, along with the implementation of a wick drain and surcharge program to pre-consolidate the Bay Mud.
Rockridge Geotechnical (RG) reviewed the performance of the mitigation measures and provided input on the wick drain and surcharge program. RG also performed a supplemental geotechnical investigation to confirm subsurface conditions following the implementation of mitigation measures and to develop design-level geotechnical recommendations.
RG provided consultation during the final design and construction permit application. RG is currently providing geotechnical observation and testing services during the construction of the project.
