McCluskey,Public Works Director Prepared by: Daniel Van Beveren, Civil Engineer-Dug SUBJECT: Street Reconstruction/Resurfacing—Fall 2001 Specification No. 90012C CAO RECOMMENDATION: 1. Approve plans and specifications for"Street Reconstruction/Resurfacing—Fall 2001". 2. Authorize staff to advertise for bids. 3. Authorize the CAO to award the contract if the lowest responsible bid is within the engineer's estimate of$1,250,000. 4. Authorize the transfer of $614,707 from the South Higuera Street Rehabilitation project account to the 1999/2001 Street Reconstruction/Resurfacing account. DISCUSSION The City's Pavement Management Plan (PMP) was adopted by the City Council on April 14, 1998. The key elements of the PMP are the establishment of eight principal areas within the city, and a maintenance plan in which each of these eight areas will receive maintenance over an eight-year period. Streets located in the central downtown area are not part of this rotation because they require maintenance more frequently. This project reflects required major pavement work in Area 4. Earlier this year, Chec Engineering Consultants, Inc., a private consulting firm specializing in pavement design and deflection testing, was awarded a contract for engineering services. They performed structural testing of selected City streets primarily located in pavement areas 4 and 5. The streets tested were those that had already been selected for rehabilitation based on the City's Pavement Management Plan (PMP), which utilizes the computer program MicroPaver. Chec Engineering Consultants, Inc. conducted the tests using the dynaflect method, a nondestructive testing method of determining a street's structural integrity. As part of its contract with the city, Chec Engineering Consultants, Inc. issued its findings in a report, "Deflection Testing/Analysis Structural Pavement Recommendations," in which test results and design recommendations are presented. CAO recommendation item #4 listed above is the transfer of $614,707 from the South Higuera Rehabilitation project account into the 99/01 Street Reconstruction/Resurfacing account. Prior to advertising for bids,the South Higuera project received a transfer of$925,000 from the 99/01 Street Reconstruction/Resurfacing account. Because the lowest bid on the South Higuera Rehabilitation project was considerably lower than the engineer's estimate, $614,707 can be transferred back into the 99/01 Street Reconstruction/Resurfacing account and will not be needed for the South Higuera Rehabilitation project. Utilization of this money for major pavement work in Area 4 is consistent with the City's adopted Pavement Management Plan.
