鶹ƵWraps Up Phase Two of Louisville's Portland CSO Basin Project
Geotechnical general contractor 鶹ƵConstruction recently completed their second contract for Kentucky’s Louisville and Jefferson County Metropolitan Sewer District’s Waterway Improvements Now (WIN) program.
The WIN program was created as an aggressive response to a Federal Consent Decree to control sewer overflows and improve water quality in the Louisville metro area for its nearly 700,000 residents.
The first part of the WIN project, which must be in place by 2020, included the installation of multiple basins to retain a mixture of rainwater and sewage during heavy rain events that would gradually be released for treatment rather than overflowing the system and polluting waterways.
鶹Ƶwas contracted by general contractor Dugan & Meyers to install a 42-inch thick, 239-foot diameter concrete diaphragm wall to act as a temporary support of excavation (SOE) shaft.
The second part of Nicholson’s contract involved the installation of 232 vertical tiedowns to ensure that the basin’s structural foundation mat would resist uplift pressure.
“We worked closely with Dugan & Meyers and the owner’s engineer to develop a value-engineered design concept that resulted in significant cost and schedule savings to the project,” said John Wise, Senior Vice President, 鶹ƵConstruction. "We're very proud of the CSO work we've completed all over the country and this project is no exception."
Nicholson’s work wrapped up in early April. The overall WIN project will continue through 2024.
