Rehabilitation Improvement for the Levee at Edinburg Pump Station

The work for this project generally consists of construction of levee improvements, including earthen embankment and concrete floodwalls, and associated ramps. The major construction efforts include, but are not limited to, preparing right-of-way, removing/stockpiling existing excavated material, levee widening, erosion control, demolition, installing two new sections of floodwall with bollard walls, drilled pier floodwall foundations, installing cement-bentonite slurry cutoff wall, steel sheet piling, installation of drainage blanket/chimney drain, completing construction of an existing gatewell structure, backfilling and grading of levee embankment material, installing aggregate roadway surface, riprap, removal and replacement of chain link fencing, and revegetation. Drilled piers shall be installed 30 inch in diameter and 60'-9" in length. Full depth temporary casing shall be used for all drilled piers. The contractor/subcontractor performing the drilled pier work shall have successful completion of at least three (3) separate foundation projects within the last five (5) years with drilled piers of similar size (diameter and depth) and installation difficulty to those shown in the Contract Drawings, and with similar subsurface geotechnical conditions (e.g., groundwater levels, soil classification and consistency, etc.). Cement-bentonite slurry cutoff wall shall be installed 3 feet wide, 30 feet deep, for a length of 170 feet. The contractor/subcontractor performing the slurry wall shall have successfully installed a minimum area of million (1,000,000) square feet of cement-bentonite slurry cutoff wall, including at least two projects within the last five (5) years with similar depths, lengths, and subsurface conditions.
