Pembroke Pump Station - Hallandale, Fla.
To alleviate periodic flooding to local neighborhoods in Pembroke Park and the City of Hallandale, the Florida Department of Transportation issued a request to construct the Pembroke Pump Station. Kiewit Southern Co., a subsidiary of Kiewit Corporation, was awarded the $11 million project to design and construct a new storm-water pump station.
The team constructed an at-grade precast panel pump station, four 40-cubic-feet-per-second pumps with 30-inch-diameter expansion joints, back-flow gates and butterfly valves that are connected to a 64-inch-diameter steel header pipe. The scope of work also included an electrical distribution system and motor control center with an 800-kilowat backup generator to allow three of the pumps to operate in case of a power failure; and a remote telemetry unit control system designed to communicate to the City of Hallandale's monitoring station.
The team installed 1,100 feet of 84-inch-diameter gravity line, 1,200 feet of 64-inch-diameter dip force main, 500 feet of 88-inch-diameter microtunnels and a 64-inch-diameter dissipater outfall. Major quantities included 60,000 cubic yards of canal dredging, 5,000 feet of channel excavation, 2,000 feet of cast-in-place gravity wall and 200 feet of precast box culvert.
Kiewit maintained a superior safety record with more than 37,000 hours worked without an OSHA recordable or public liability incident despite a variety of difficult work situations, including microtunneling under a major interstate, as well as excavation and structure work adjacent to a commuter and freight rail line carrying 20 loads per day.
