Gyimah Kasali
Gyimah has been with R&C for 29 years and leads the geotechnical department. He brings a philosophy of strong communication and excellent customer service to all of his projects. These traits have resulted in long-term relationships with clients such as UC San Francisco and the SLAC National Accelerator Laboratory, who call upon Gyimah when immediate geotechnical issues arise.
During his career, Gyimah has performed engineering and managerial services on many of the firm’s major projects. He routinely manages projects that involve marginal, landfill and other difficult sites; construction observation of shallow and deep foundations and excavations; evaluation of liquefaction potential of sites and studies of environmental and earthquake-induced hazards; and analysis of soil-structure interaction problems. He serves as principal geotechnical engineer on the California Academy of Sciences, UC San Francisco’s Institute for Regeneration Medicine, the new Stanford Hospital, and the Lucile Packard Children’s Hospital expansion. Gyimah is also a noted speaker who has recently lectured throughout the West Coast for the Earthquake Engineering Research Institute.
