DESCRIPTION OF WORK: The Biscayne Bay Coastal Wetlands (BBCW), Contract 5C covers the construction of Pump Stations S-710 and S-711, spreader systems, a seepage canal (C-711W), with associated berm, and the installation of a riser board assembly on the culvert located on the south bank of C-103, between S-710 and S-711, in the North Canal Wetland (NCW; the land south of C-103 being hydrated by S-710 and S-711). The riser board assembly will allow for water level management in the NCW. S-710 and S-711 are both 40 cfs pump stations located on the south bank of the C-103 that will pump water from C-103 and discharge it into the NCW through a dissipation/spreader basin and concrete-lined spreader channel for S-711 and a dissipation/spreader basin for S-710. C-711W (with the berm) will be located in the NCW, along the western boundary, to prevent NCW water from seeping to the west, onto private lands. C-711W will drain NCW seepage water to C-103, through a culvert, through the C-103 embankment. The pump stations 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, precast concrete, cast-in-place concrete, tremie concrete, flowable fill, 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. Florida Power & Light (FPL) will intercept, modify, and upgrade the existing overhead three-phase powerline at the intersection of SW 107th Avenue and 136th Street (south bank of Canal C-103 / Mowry Trail), to provide a new, overhead, three-phase powerline for Pump Stations S-710 and S-711. FPL will route the overhead powerline East along Canal (C)-103 (Princeton Trail), within the SFWMD 30-foot ROW, to the pump stations. The required run will be approximately 4,065 linear feet. FPL will provide and install overhead conductors, poles (approximate 27 poles), transformer(s), and other required hardware as shown on the contract plans, to provide a 277/480V, 60Hz, 250A service for S-711 and 277/480V, 60Hz, 250A service for S-710. 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. The performance period is approximately 1113 calendar days after Notice to Proceed (NTP). The Request for Proposal (RFP) will be issued on or about 14 June 2021 and proposals will be due on or about 14 July 2021. NAICS Code 237990, size standard $39.5 million. Magnitude of construction is between $15,000,000.00 and $25,000,000.00. THIS IS AN UNRESTRICTED ACQUISITION. ALL RESPONSIBLE OFFERORS ARE ENCOURAGED TO PARTICIPATE.
