McCrady, City Manager ,, 1 <br /> Richard G. Marley, P.E., Director o Public Works <br /> � �� , <br /> SUBJECT: Concrete Pavement Improvements: <br /> West Main Street—Diamond Grinding/Patching <br /> North Taylor Avenue—Diamond Grinding/Patching <br /> City Project 09-11 <br /> SUMMARY RECOMMENDATION: <br /> It is recommended that the City Council approve the attached resolution awarding the contract for <br /> Concrete Pavement Improvements, City Project 09-11, to Kinney Contractors, Inc., as the lowest, <br /> responsible bidder in the amount of$582,357.50, and that the Mayor be authorized to execute the <br /> contract, and the City Clerk to attest. <br /> BACKGROUND: <br /> Prior Council Action <br /> The Concrete Pavement Improvement Project is an annual street improvement project for the City. <br /> Project Description <br /> The project consists of concrete patching, installing dowel bars, repairing cracks, and other necessary <br /> pa�ement repairs prior to diamond grinding on West Main Street between Victoria Place and Wyckles <br /> Road and on North Taylor Avenue between King Street and Grand Avenue. West Main and North <br /> Taylor are concrete streets with faulted joints and deteriorating pavement. The proposed repairs will <br /> replace damaged sections of concrete and strengthen the remaining sections with added reinforcement. <br /> The concluding treatment will be grinding off up to '/z" of the surface to restore the pavement to a <br /> smooth condition which will reduce the damage caused by traffic impacts to the faulted joints and <br /> cracks. Diamond grinding is a common pavement treatment that uses a series of diamond tipped saws <br /> to remove a small amount of the pa�ement surface in order to smooth out bumps and faults. <br /> Alternate Bid <br /> Diamond grinding on Taylor Avenue was proposed as an alternate bid due to concern with the <br /> estimated project cost. It was determined that this portion of the work could be completed at another <br /> time if costs exceeded the funding allocated for the work. <br /> Page � 1 <br />
