Description of Work: The project work includes the removal of the existing concrete cap of the bulkhead walls, installation of new steel sheet pile bulkhead walls with cast-in-place concrete cap and precast concrete wall panel cap, site grading, and mechanical/plumbing/electrical equipment replacements and additions, and storm water outfall pipe extensions. The work also includes the removal and replacement of the asphalt/concrete pavement, timber guide and mooring piles, floating docks and aluminum ramps (where indicated on the plans), and modification of the fixed docks. The overall project site components encompass work to done within and around the four marina basins (Whitewater Bay, Florida Bay, Visitor Center Bay, and Maintenance Marina Bay) located at the Flamingo Marina in the Everglades National Park. Shallow draft barges or similar is authorized, with approval by the Government, for use so long as dredging of the basins is not required, at no additional cost to the Government. Specific project components include the following items and incidental related work: The new sheet pile bulkhead wall systems are comprised of a total of approximately 3,900 linear feet. The installation of the sheet pile walls is offset 22 inches from the existing bulkhead walls for Whitewater Bay, Florida Bay, and Maintenance Marina Bay; and offset 22.5 inches from the existing bulkhead walls for Visitor Center Bay. The offset dimension is measured from the exterior face of the existing soldier piles to the centerline of the sheet piles. Flowable fill will be placed between the two wall systems. The precast concrete wall panel cap will overhang the sheet pile walls and tied into cast-in-place concrete cap, resulting in both wall systems being encompassed. The placement of the wall systems must not extend through the canal plug between Whitewater Bay and Florida Bay, and the structural canopy in Maintenance Marina Bay. The floating docks and aluminum ramps affected by the placement of the new wall systems (indicated on the plans) will be removed, stored, and reinstalled in approximately the same location. The affected docks will also include the removal and replacement of the timber guide and mooring piles. The fixed docks will remain in place with only the affected portions to be removed, modified, and reinstalled. Areas that involve work for the floating and fixed docks are located in Whitewater Bay and Florida Bay. The replacement of all the floating docks (indicated on the plans) must be replaced with aluminum floating docks and are identified as Option A of the project. The mechanical/plumbing/electrical equipment replacements and additions for Whitewater Bay, Florida Bay, and Maintenance Marina Bay will include the removal and replacement of utility pedestals, boat off-loading sewage pumps, fuel dispensers, electrical (circuit breaker) panels, plumbing and wiring/conduits for the equipment, sewage shore ties, and equipment housekeeping pads. The mechanical/plumbing/electrical equipment replacements and additions will also include the removal of the makeshift water stations on the east side of the Marina Store and the installation of a packaged utility wastewater pumping station (grinder pump) at the south wall of the Maintenance Marina Bay.
