October Luncheon Meeting

The ASCE Louisville Branch will be hosting the October 2024 meeting on Thursday, October 10th at the University of Louisville Club (UClub). At this month's meeting Brandon Flaherty (MSD), Mike Rudisell (HDR), and Nick Ulliman (Ulliman Schutte) will present Collaborative and Innovative Design for the 1,900-MGD Paddy’s Run Flood Pump Station.

Presentation Description: Ulliman Schutte and HDR are cooperatively designing and constructing the new Paddy’s Run Flood Pump Station for Louisville MSD using Progressive Design-Build project delivery. The project is currently under construction and will be completed in 2027. Progressive Design-Build delivery is being utilized to foster collaboration between the Owner, Engineer, and Contractor; expedite an aggressive schedule; and promote innovation. Louisville MSD is replacing the existing station with an upgraded facility to be able to pump a maximum flow of 1,900 MGD to protect the community when the Ohio River reaches flood stage. The pump station layout was designed with a unique opposite/offset configuration to reduce overall footprint and minimize impact to the levee system. Also, construction of a deep diaphragm wall system will provide seepage “cut-off” and furnish the building with its permanent foundation system to meet current USACE standards. Further, all required electrical, mechanical, and instrumentation will allow the automated operation of the new flood pumps including integration into MSD's SCADA system. There were several tools used during design including physical modeling, CFD analysis, and virtual reality. Physical models were constructed in a laboratory at a 12:1 scale to verify the design concept for both the intake/wet well and the discharge pipe/siphon head recovery system. A CFD model analysis was used in the design of the pump station’s discharge basin to quantify the maximum hydrodynamic forces and optimize the design of the structural pile foundation system.
