BKI was contracted by the Jefferson Parish Council to design and provide construction administration for a new 4,600-cfs storm drainage pumping station on Duncan Canal at the Lake Pontchartrain levee in Kenner, Louisiana. BKI designed the concrete sump and pile-supported pump foundation; steel-grate trash racks and screen cleaners; four 1,000-cfs diesel-powered horizontal pumps; two 300-cfs direct-drive electric powered vertical-lift storm pumps; formed concrete discharge tubes; and the pump house superstructure, including an overhead travelling crane, a diesel fuel storage system, a vacuum pump priming system, emergency generators, and concrete floodwalls and levees. As part of the design process, BKI's engineers analyzed lateral loads on floodwalls from storm surges and on the pump station structure from hurricane velocity winds. BKI also provided construction administration and full-time resident inspection services during construction.
