Client: Rutherford & Chekene as performed for UC Davis
Location: Davis, California
Period of Performance: 2003
Project Description: The intent of proposed work was to construct soil-cement columns to
strengthen weak and potentially liquefiable soils beneath the to-be-constructed building
foundation in order to substantially reduce the risk of earthquake induced ground movement
sufficient to result in foundation failure. The soil-cement column elements are expected to
resist ground movement in shear, and steel pile inserts were incorporated to provide a high level
of assurance of column continuity, strength and "ductility" in shear.
Task: ADH provided observation of installation activities and representative sampling for
the construction of over 200 36-inch diameter soil-cement columns to depths up to 40-feet below
ground surface as part of a foundation stabilization program located at University of California,
Davis campus in Davis, California. Observation and reporting procedures were performed in
accordance with the requirements specified by Rutherford & Chekene.
