71 -DI <br />REPORT <br />To the Honorable Mayor and City Council <br />From the City Manager <br />July 14, 2003 <br />Subject <br />Award of Contract — 2002 -2003 Asphalt Rubber Chip Seal Project. <br />Engineering File No. 806 -02 <br />Recommendation <br />Approve the Contract Documents and award the contract for the 2002 -2003 Asphalt <br />Rubberized Chip Seal Project to the lowest responsible bidder, Western States <br />Surfacing Inc. of Modesto, California, for their low bid of $498,954.68. <br />Background <br />This year's project is a continuation of the "Cape Seal" Program, and targeted again for <br />the lower traffic volume /residential streets. Because this "cape seal" method is done in <br />two separate procedures, it calls for two separate contracts (i.e., chip seal and slurry <br />seal). By breaking this project into two separate contracts, the work will be coordinated <br />directly with the contractor performing each specialty item, thus eliminating the prime <br />contractor's mark -up, usually associated with subcontractors. With the City directly <br />coordinating the specialty contractors, we should be able to achieve a better quality <br />project as well. <br />Advance preparation work is necessary prior to the start of the Asphalt Rubberized Chip <br />Seal Project. This work involves sealing cracks and leveling the existing surface with a <br />thin layer of asphalt to smooth out the depressions, ruts, and raveling, typical of badly <br />deteriorated streets. This preparation work is currently being performed by the City's <br />Public Works Services Street Maintenance Section, and will be completed as <br />scheduled before the Asphalt Rubberized Chip Seal Project begins. Once the Asphalt <br />Rubberized Chip Seal Project is finished, the Slurry Seal Project will begin <br />approximately two weeks later, which will then complete the "Chip Seal" resurfacing <br />method. <br />The stages of construction for the project are as follows: <br />Removing the roadway striping and covering the manhole, valve box, and <br />other utility boxes. <br />2. Application of the rubberized chip. <br />Total construction time for the 2002 -2003 Asphalt Rubberized Chip Seal Project is <br />fourteen (14) calendar days. <br />Page 1 of 2 <br />
