APPROVAL OF CAPITAL PROJECT AMENDMENT FOR BRADLEY CREEK SEWER JUNCTION BOX REPLACEMENT AND ADOPTION OF BUDGET ORDINANCE AMENDMENT 2008-80 Interim County Engineer Dennis Ihnat reported that the Bradley Creek sewer junction box replacement capital project ordinance was approved by the District on August 13, 2007 with the contractor, T.A. Loving, beginning the work on the site in mid-September. During the course of the work, it was discovered that the original 24 inch effluent line that connects the junction manhole to the pump station is defective and needs to be replaced. This line replacement was not in the original scope of work per Change Order #4. Additionally, a new interconnect for the Northeast Interceptor flow management, new force main sample taps, and a new connection for the odor control vent pipe to the junction box are required as a result of the reconfiguration of the incoming force mains to the junction box. At the District's request, T.A. Loving has submitted estimated cost for these items. The cost to install the new effluent line and other needed upgrades is $239,500. This figure also includes the cost of the revised bypass pumping that is needed to complete the additional work. NEW HANOVER COUNTY WATER AND SEWER DISTRICT BOOK 3 REGULAR MEETING, JANUARY 22, 2008 PAGE 270 This additional work is critical to ensuring a quality project with regards to upgrading the County's lines and manholes at the pump station, returning the station to a normal operating mode so the City can complete all the required pump station upgrades required by the Special Order of Consent and ensuring safe and effective operation of this critical infrastructure link in the Northeast Interceptor system. Timely completion of this project will assist the City in completing the required work so the Northeast Interceptor moratorium and Special Order of Consent can be removed. Staff is requesting the District Board approve the capital project amendment for the Bradley Creek Sewer Junction and adopt the Budget Ordinance Amendment 2008-80 in the amount of $239,500.
