DRTO 244370/244372 Repair and Dredge Ft Jefferson   4

Background
The solicitation is for the repairs to the Fort Jefferson Counterscarp and the dredging of Fort Jefferson Moat and Fingerslips at Garden Key Waterfront at Dry Tortugas National Park. The work involves repairing recently damaged areas of the counterscarp with new materials and methods to achieve a more durable structure, as well as dredging the slips and finger piers at the Garden Key Waterfront to allow for continued unobstructed recreational and park use of the dock and slips, and removal of significant filling of sand and silt material in the moat surrounding Fort Jefferson.

The exterior of Fort Jefferson includes two major features, the Scarp and the Counterscarp. The Scarp is the exterior face of Fort Jefferson. The Counterscarp is the seawall around Fort Jefferson which protects the Scarp from the ocean’s energy and forms a moat between the two.

Work Details
The work includes repairing recently damaged areas of the counterscarp with new materials and methods to achieve a more durable structure. This repair option will address the collapsed section and complete wall repairs with new material and techniques while matching the historic fabric. Materials and methods will be chosen based on durability and compatibility with the fort's historic features. Once repaired, revetment will be placed in select locations at the base of the walls to aid in hardening and prolonging the counterscarp's life from future wave energy and scour. Coral relocation planned to be performed by the Park prior to construction beginning.

The project also involves dredging of hurricane accumulated sand deposits at Fort Jefferson, including dredging of slips and finger piers at Garden Key Waterfront to allow for continued unobstructed recreational and park use of the dock and slips, as well as removal of significant filling of sand and silt material in the moat surrounding Fort Jefferson.
