Key Info

Rapid load test on prototype drilled piers

R+C was the structural and geotechnical engineer for the much-needed housing addition. The infill housing consists of three new mid-rise suite-style dormitory buildings that accommodate 884 beds. Each unit is 60,000 sf. A fourth, equal-sized building provides 40 apartments. Two dining facilities were demolished and landscaped central courtyards were built over 10,000 sf of renovated basement support areas. The project was designed to LEED Silver standards.Savings from the Ground UpGeotechnical services included directing the performance of a rapid load test (using PLT equipment) on prototype drilled piers to simulate their response under earthquake loading. R+C used the test results to develop criteria for drilled pier capacity and stiffnesses in collaboration with our structural engineers. The tests led to foundation cost savings in the hundred thousands

Gyimah Kasali

Project Manager/Geotechnical Engineer

Gyimah has been with R+C for over 35 years and leads the geotechnical department. He brings a philosophy of effective 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 geotechnical issues arise that require an immediate response.

Gyimah has provided engineering and management on most of the firm's major projects. He routinely leads projects that involve marginal, landfill and other difficult sites; evaluation of liquefaction potential of sites and studies of environmental and earthquake-induced hazards; and analysis of soil-structure interaction problems. He served as principal geotechnical engineer on the California Academy of Sciences, de Young Museum, UC San Francisco's Ray and Dagmar Dolby Regeneration Medicine Building, the new Stanford Hospital, and the Lucile Packard Children's Hospital expansion. Gyimah is also a noted speaker who has lectured on performance-based design along the West Coast for the Earthquake Engineering Research Institute.

Gyimah is currently serving as a member of BSSC Provisions Update Committee (PUC) for the NEHRP 2020 Provisions, Engineering Design Review Team (EDRT) for the City of San Francisco Department of Building Inspection, and the Advisory Committee on Structural Safety of Department of Veterans Affairs (VA) Facilities.

Leavening peerless structural engineering skill with humor, philosophy, people skills and, above all, a consummate understanding of San Francisco's permitting process, [Alan] saw this project through.
