Principal-in-Charge for the geotechnical and seismic investigations and recommendations for expansion.

Principal-in-Charge for the Centennial Drive Overpass-Geotechnical investigation of slope failure endangering integrity of the overpass structure. Investigations included drilling, pump tests, and comprehensive strength tests, as well as analysis of the concrete overpass structure. Subsequently designed the slope modifications, including drainage measures and preformed the construction overview of slope stabilization measures.

Principal-in-Charge for the comprehensive evaluation of the geology, groundwater, and material strength properties to determine the causes of continued creep and failure of the slopes of the hillside areas of UC Berkeley Campus; including airphoto analysis, geologic mapping, installation and monitoring of piezometers and pump wells and conducting pump tests to assess local and semi-regional permeabilities of different strata, installation and monitoring of slope indicators, development of groundwater topography, identification of zones of low permeability and potential instability.

Principal-in-Charge for geotechnical investigations for grading and construction of Botanical Garden parking area.
