In order to construct the Fuller Creek Regional Pumping Station, Civil Constructors, Inc. hired WHA to design a circular cofferdam. The eighty-one-foot diameter cofferdam was forty feet deep, utilizing PZ 27 sheet piling and had two 2’-6” square concrete waler rings. The two concrete waler rings were constructed when excavation reached the bottom of the concrete rings. Dewatering wells were also placed outside of the cofferdam to help keep the water level to a minimum for reduced pressure.
