Description
Construction of the Indian Creek Dr. (SR A1A) Improvements from south of 25th Street to 41st Street. Indian Creek Dr. (SR A1A) is a Florida Department of Transportation (FDOT) roadway and as such construction of this project complies with all applicable FDOT manuals, memorandums and guidelines including a Pump Station with three (3) 14,000 GPM pumps, water treatment and backup bi-fuel generator. This work includes earthwork, raising the elevation of the roads within the project limits to minimum crown elevation of 3.7 feet North American Vertical Datum of 1988 (NAVD) and transitioning into crossing streets; harmonization of all adjacent properties, installation of a new 72” diameter drainage system, yard drains and/or driveway trench drains. The triplex pump station includes three (3) Flygt PL7040, 460V Flygt submersible axial pumps controlled by variable frequency drives and Flygt’s Multi Smart control panel aligned for SCADA control. The 400kw Kohler backup generator is bi-fuel type (NG & Diesel) with Auto transfer switch to ensure power reliance. Water quality is ensured by EcoSense filtration system located in three (3) filtration structures and a fixed trash rack; discharge is via a dissipator box into Lake Pancoast. The work included a tie-back stabilization of the previously installed pre-cast structures to house the pumps via Concrete Pile and Beams to prevent settlement under operational load adjacent to the water way.
