- Description
- The BBCW Contract 5A covers the construction of Pump Station S-705.� The S-705 pump station has a capacity of 100 cfs and is located on the L-31E Canal at the intersection with the C-102. S-705 will pump water into an L-31E Canal segment, south of C-102 and north of Military Canal.� The water in this segment will flow, through culverts, into wetlands east of the L-31E Levee.� S-705 will also feature a 72-inch culvert with a slide gate to pass flows for internal drainage. The pump station will have manatee protective barriers, trash racks, and dewatering features, complete with stop logs.� The slide gate at S-705 will be operated by an electric-motor actuator.� Controls will be located in a stand-alone, precast concrete building adjacent to the pump station structure.� The pumps and gate will have remote operation capability. Construction activities include installation of precast concrete, H-piles, king piles, sheet piles, concrete piles, precast concrete, cast-in-place concrete, tremie concrete, flowable fill, an HDPE culvert, a slide gate, precast, concrete, control buildings, pumps, pump platform, pump station controls, electrical work, lighting, lightning protection, fencing, excavation, backfilling, stockpiling, clearing and grubbing, grading, placement of topsoil, sodding, limerock road topping, riprap and bedding stone, installation of stilling wells, stilling well platforms, staff gauges and floating barriers. Additional construction activities may include dewatering, and installation of cofferdams. In-water construction utilizing divers will be necessary, because of dewatering difficulty due to the local geology and high conductivity of the underlying limestone. Soil borings indicate the presence of hard limestone within the project area.� Excavation of limestone may require large excavator with rock bucket.� Materials for embankment and backfill construction can be obtained from offsite sources provided by the Contractor and approved by the Contracting Officer or the Contractor can process the excavated material to meet the classification of satisfactory material for embankment fill and or select fill at no additional cost to the Government.�Contract does not allow blasting within the construction limits.
