Exfoliation: not the first thing that would come to mind when planning a summer vacation. Residents and vacation goers in Twain Harte, California became quite familiar with this geologic phenomenon when the dam at Twain Harte Lake was damaged in August of 2014 due to exfoliation of the granite dome that serves as the south abutment. Condor assisted the Twain Harte Lake Association in identifying the cause of the damage, designing repairs to the dam and south abutment, getting approval from the California Division of Safety of Dams (DSOD) for the repair, and managing the repair of the dam and abutment.
Condor is currently providing earthwork quality control and concrete testing services for the Eight Mile Road Grade Separation Project in North Stockton and the Sperry Road Extension near French Camp. The Eight Mile Road project consists of two overpasses and one underpass which will provide for continued traffic flow between Interstate 5 and Highway 99. The improvements provide three grade separations for two railroad lines that continue south through Stockton. Condor’s client is Psomas Construction Management and the project is funded by the City of Stockton and Measure K.
