Harbor Wastewater Replacement Tunnel for the City of Charleston

Harbor Wastewater Replacement Tunnel for the City of Charleston

Charleston, South Carolina

Stiver Engineering was retained to provide structural design through a contractor with two caisson designs for the City of Charleston, South Carolina. We designed the reinforced concrete structures to be poured in lifts and sunk into the earth until the cutting edge of the caisson reached the design elevation. Our engineers also provided the client with a braking system design that could be activated if the caisson had difficulty stopping at the design elevation.

The two caissons were constructed on Plum Island, and Stiver Engineering provided both mechanical and structural plans to the contractor for construction.
