LDA provided design, construction engineering, and resident project representative services for upgrades to a water booster pumping station for the Knoxville Utilities Board. The booster pumping station upgrade included the addition of a 125 horsepower, 2000 gallons per minute, pump to an existing booster station with three 2,100 gpm (100 horsepower) pumps and a 75 horsepower pump (which was replaced by the new 125 horsepower pump).
The project included necessary piping and valves to replace the existing pump, new electrical switchgear to drive all 4 pumps, new instrumentation, and a new SCADA panel with a PLC to control the pump operations. Since the pump station could not be totally taken out of service, a temporary electrical service and motor starter was designed to maintain operation of one of the larger existing pumps while the new MCC was installed.
Due to the requirement for the new MCC, code requirements necessitated the expansion of the existing building to maintain clearances between the MCC and mechanical equipment. KUB also requested that a new bridge crane be installed to assist in moving pumps and motors in and out of the building. The existing structure housing the equipment was constructed in a manner that did not allow for expansion. LDA specified a pre-fabricated metal building that was constructed around the existing structure, which was them removed after the new building was at a point where the equipment could be protected from the weather.
Due to the complexity of the project with respect to scheduling and construction issues, the closest coordination between KUB, LDA, and the contractor was necessary to make the project a success.
