In 2007, Cantsink was hired to provide support for the foundation of a three-story addition to downtown Savannah’s Ralph Mark Gilbert Civil Rights Museum.
The original building is a former bank built in 1914 to serve the African-American community. The renovated structure was opened as the Civil Rights Museum in 1996.
The contractor, Collins Construction Services, hired Cantsink to provide foundation support for the addition and soil testing was conducted by Whitaker Laboratory, Inc., a geotechnical engineering firm, to determine the level of support needed to stabilize the structure.
Concern for the existing structure, helical piles were recommended in lieu of traditional pile driving systems that cause vibration.
Because of the limited space required for helical pier installation, the work proceeded concurrently with excavation, saving valuable construction time in volatile coastal weather conditions.
