Santee Cooper is South Carolina's state-owned electric and water utility and serves more than 150,000 residential and commercial customers in Berkeley, Georgetown and Horry counties. In order to meet the demands of a growing population, Santee Cooper is building a new $984 million coal-fired generation facility along the Great Pee Dee River near Pamplico, South Carolina.
WPC is providing a comprehensive geotechnical investigation for this 600-megawatt (MW) pulverized coal facility which is estimated to begin commercial operation in January of 2014. WPC will identify the geologic formations and develop the subsurface profiles of the site underlying the power blocks and other structures through the analysis of existing data, and performing soil test borings, cone penetration test (CPT) soundings, and dilatometer test (DMT) soundings as well as geophysical surveys.
Laboratory testing is used to characterize the soil properties in terms of strength, compressibility, and dynamic parameters such as shear modulus and damping. The data will be applied to the geotechnical evaluation and foundation recommendations. Laboratory testing takes place in WPC’s accredited laboratories.
WPC’s geotechnical engineering evaluation will provide foundation alternatives for structures located within the project and provide recommendations for the most suitable and cost-effective foundation system for each of the structures based on the settlement, bearing capacity, seismic analyses, and the specific performance requirements for the structures.
