AGENDA DESCRIPTION Construction and installation of the North Louisville Interceptor Sewer is proceeding on schedule. The contractor has installed sewer line from the Wastewater Treatment Plant to South Boulder Road. The original bid specifications specified that South Boulder Road was to be crossed with open cut construction and temporary roadways was to be installed adjacent to the current South Boulder Road. The project bid in early 1986 identified a jack and bore whereby the pipe would be pushed under the road and no disruption of traffic would occur . Due to the high cost on the original bid, the City eliminated this more expensive item of work from the rebid project . Because favorable bids were received on the rebid project , the City asked the contractor to evaluate additional costs to jack and bore the South Boulder Road crossing rather than open cut it. The purpose for this type of construction versus open cut, is that it provides much greater safety to the motoring public and exposes the contractor and the City to much less liability. Jack and bore of the South Boulder Road crossing would also eliminate the inconvenience and disruption to traffic that is inherent in an open construction with temporary roadway repairs. The contractor submitted to the City a Change Order identifying an additional $3095.00 in project cost in order to cross South Boulder Road with a jack and bore operation versus a open cut technique.
