This is a $6,119,056.00 firm fixed price definitive contract awarded by the National Park Service (NPS), a civilian agency, to Jay Cashman Inc. for the replacement of two failed plugs (dams) at Cape Sable in Everglades National Park in Florida. The objective is to reconstruct the failed dams on the East Cape Canal Extension and Homestead Canal with minimal impact on the natural conditions. The work includes establishing a staging area, mobilizing personnel and equipment, clearing vegetation, removing the existing failed sheet pile wall dams, and replacing them with 100-foot plugs contained by sheet piling or geotubes. Recreational components like floating docks and walking paths will also be constructed. This contract does not have a set-aside designation.

TAS recovery ever pmis #152464 - replace two failed plugs (dams) at cape sable (east cape and homestead canal dams). The objective of the project is to reconstruct the failed dams on the east cape canal extension and homestead canal with minimum impact on the natural conditions. Currently, the failed dams allow seawater to cyclically flush into and out of the park on a daily basis in response to normal fluctuations in tide elevations. The following are the general work elements: 1) establishment of a permitted landside staging area in the florida keys or elsewhere on the west or east coasts of florida for the staging, loading and movement of equipment and materials to be used in construction. 2) mobilization of personnel, equipment and materials to the offshore and canal staging areas. 3) limited clearing of vegetation in the immediate work site areas and trimming of mangrove trees and other vegetation along the canal banks as required accessing the work sites. 4) the removal of two (2) existing failed sheet pile wall dams on the east cape canal extension and homestead canals. Existing sheet pile wall dams are to be completely removed or cut off at the bottom of the canal just above the MUD line and removed from the park. 5) the failed dams are to be replaced with plugs of back fill 100 feet in length and contained by either new sheet piling or geotubes at the ends of the plugs. Upstream and downstream areas adjacent to the end plug containments are to be protected by a graded RIP RAP system. 6) downstream and upstream erosion protection using riprap is proposed for both DAM sites to prevent bank erosion in the areas immediately downstream of the DAM containment system. 7) recreational components will constructed at each DAM site to consist of a pile restrained floating dock and landing area for canoes and kayaks. A hardened walking path consisting of a concrete in filled geoweb underlain by geotextile fabric is to be constructed across each fill plug to provide portage for canoeist, kayakers, fisherman and others visiting the area. 8) miscellaneous improvements including channel markers, mooring buoys and other signage are to be constructed for the project. The project will be constructed under a single prime contract.
