Description
The Biscayne Bay Coastal Wetlands (BBCW), Contract 5B covers the construction of Pump Station S-703, a spreader system, and two recreational sites. The S-703 pump station has a capacity of 50 cfs and is located at the intersection of the C-102 and L-31E Canal. S-703 will pump water from the L-31E Canal/C-102 into wetlands, east of the L-31E Levee and north of the C-102, via a dissipation/spreader basin and an earthen spreader canal. The two recreational sites will be located east of the L-31E Levee and north of the C-102, near Biscayne Bay. Work will include construction of a shelter with information kiosk, and two tent sites/pads. The pump station will have manatee protective barriers, trash racks, and dewatering features, complete with stop logs. Controls will be located in a stand-alone, precast concrete building adjacent to the pump station structure. The pumps will have remote operation capability. Construction activities include installation of precast concrete, H-piles, king piles, sheet piles, concrete piles, cast-in-place concrete, tremie concrete, flowable fill, control building, 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. FP&L will provide 3-Phase, 277/480V service for S-703 by way of a new 3-Phase, OHE powerline to S-703, coming from pump station S-705 to the south, and from the west side of L-31E Canal. Also, in coordination with the South Florida Water Management District (SFWMD), FP&L will relocate the 1-Phase, OHE powerline, serving spillway S-21A, as it is currently in interference with project features. The relocated 1-Phase, OHE powerline will be installed in locations where it will not interfere with construction features/activities. This work will be complete before this contract is awarded. 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. PROPOSAL REQUIREMENTS : AWARD WILL BE MADE TO THE OFFEROR WHO SUBMITS THE LOWEST PRICED, TECHNICALLY ACCEPTABLE (LPTA) PROPOSAL. PROPOSALS WILL BE EVAULATED BASED ON TECHNICAL ACCEPTABILITY (DEMONSTRATED EXPERIENCE AND PAST PERFORMANCE) AND PRICE.
