The resolution authorizes the Mayor to increase the existing $40,175.00 contract amount by$10,000.00 for a maximum of$50,175.00 for the work that is necessary to complete the project, and the City Clerk to attest. BACKGROUND: On November 7, 2005, the City Council authorized a $40,175.00 contract with Entler Excavating Co., Inc., to remove and replace a failed section of water main and a non-functioning valve in the water main feeding the South Shores area. The water main is located in the median in U.S. Route 51 just north of Southside Drive. The project began in December 2005, and is currently on hold until spring for final landscape restoration to be completed. Added project costs were incurred as a result of a difficulty in precisely locating the water main due to its significant depth and the necessity of replacing more damaged water main than originally expected. Although the project is not completed, the final cost is expected to be less than $10,000 over the original amount approved by Council. The additional excavation work and increased pipe replacement quantities were not anticipated, were consistent with the project, and in the best interest of the City in order to complete the project. POTENTIAL OBJECTION: There are no known objections to this resolution.
