This temporary sheet piling is already 15′-0″ into the ground and currently stands more than 50 feet in the air.  The piling will be driven completely into the ground to serve as a temporary cofferdam for a new concrete structure that will be part of an underground coal handling system.  CSA was responsible for the design of the sheet piling, ring beams, and wall supports for this project.   The structure is being built in Pasadena, TX by Continental Construction.
