The Saluda Dam impounds Lake Murray, which is one of the largest lakes on the east coast of the United States. The Dam is an earthen embankment completed in 1930 as part of a 206-Mv hydroelectric facility and is thereby under jurisdiction of the Federal Energy Regulatory Commission (FERC). A coal fired electric facility (McMeekin Station) is also located near the downstream toe of the Dam. In response to a directive from the FERC, the client initiated an engineering remedial design for dynamic seismic loading conditions. The selected remedial design consists of constructing a combination of Roller Compacted Concrete (RCC) and rockfill berms along the downstream toe of the existing Dam. Terracon was selected by the design team to support the field and laboratory quality control testing of RCC and rockfill berms. Terracon was also contracted by the client to support the geotechnical instrumentation procurement, installation and data acquisition system.
