Initial work has included drilling a number of wells for use in pumping groundwater away from the site while the manhole, more than 20 deep, is reconstructed.
Over the last year, the Kentucky Transportation Cabinet has been negotiating with T&C Contracting, prime contractor on the $13.4 million Kentucky 2121/Southtown Boulevard widening project, and the Owensboro Regional Water Resource Agency to complete repairs to the site along the boulevard’s intersection with Goetz Drive.
Ongoing lane restrictions, sanitary sewage diversion and city street closures resulting from the manhole failure have inconvenienced motorists, residents and businesses.
“The existing manhole failed after new connections were made causing the need to bypass the entire manhole with pumping through above-ground piping. The contractor rebuilt the manhole and it collapsed again, bringing work to a halt,” said Kevin McClearn, Chief District Engineer of Department of Highways District 2, Madisonville.
But after negotiations, the contractor is back to work with a new design and a new agreement that utilizes Ted Lolley & Associates, Vector Engineering, and Johnson, Depp and Quisenberry for design and geotech services. The arrangement is similar to a “design-build” project that allows engineers to match construction design to actual conditions as on-site work progresses. Funding provided by the Transportation Cabinet is on a “cost-plus” basis.
T & C Contracting of Louisville is the prime contractor on the $13.4 million project. The Kentucky 2121/Southtown Boulevard widening project included reconstruction and extensive utility work along a 1.8-mile section of Southtown Boulevard from Kentucky 2698/Carter Road to U.S. 431/Frederica Street. Completion had been expected in June 2013.The contractor and KYTC engineers have as a goal the completion of the manhole repair by the end of 2014.
