<br /> <br />REPORT <br /> <br />To the Honorable Mayor and City Council <br />From the City Manager <br /> <br />June 26, 2000 <br /> <br />Subject <br />Advertisement for Bids for the 1999-2000 Slurry Seal Project <br />Engineering File No. 806-02 <br /> <br />Recommendation <br />Adopt a resolution approving the Contract Documents entitled, "Contract Documents for <br />the 1999-2000 Slurry Seal Project", and authorize the advertisement for bids. <br /> <br />Background <br />In 1994 and 1995, the City introduced the Pavement Management System (PMS), <br />which is a data base of existing roadway conditions of all Redwood City streets and <br />roadways. The PMS System keeps and calculates the Pavement Condition Index <br />(PCI), which is the basis of selecting streets for our continuous roadway improvements <br /> <br />The City updated the PMS database in late 1999. Due to the results of the new PMS, <br />the staff recognized that the City should apply the following treatment to the roadway <br />system as part of the routine yearly roadway maintenance and rehabilitation program: <br /> <br />1. Maintenance treatment (Slurry Seal) for streets that are in good condition (PCI of <br />70-90). This treatment maintains and improves the existing condition of the <br />roadway with significantly low costs compared to doing street overlay. <br /> <br />2. Thin overlay/cape seal for streets in fair condition (PCI of 50-70) to prevent <br />further deterioration. <br /> <br />3. Thick asphalt overlay for deteriorated streets with PCI of 25-50. <br /> <br />The slurry seal, thin overlay, and thick overlay are done in three separate procedures, <br />the staff decided to call for three separate contracts. By breaking the roadway <br />maintanace and rehabilitation program into three separate contracts, the work will be <br />coordinated directly with the contractor performing each specialty item, thus eliminating <br />the prime contractor's mark-up usually associated with subcontractors. With the City <br />directly coordinating the specialty contractors, allowing them do what they do best, we <br />should be able to achieve a better quality project as well. <br /> <br />This year's Slurry Seal Project targeted the residential/arterial streets in the Redwood <br />Shores area, and major arterial roadways in the City's downtown area. <br /> <br />. ~..-. . .._~ .lr <br />
