New 55 foot wide by 150 foot long by 25 foot deep boat slip cut into the bank of the St. John’s River. The walls of the new slip serve as the runway for a large 600 metric ton boat lift crane in addition to retaining the surrounding soils from entering the slip. Steel sheet piling was used for the walls of the slip and 24 inch square straight and battered precast concrete piling was used for the support of the boat lift crane and lateral stabilization of the sheet pile wall. Extensive consideration was given during the design to accommodate drainage piping, to maintain stability of the existing bulkhead along the River, to minimize the chance of construction sediment entering the River, and to maximize the protection of marine mammals during construction.
