Walter, Director of Public Work s Prepared By :Manny Guzman, Engineer II I SUBJECT : JOHNSON, SOUTHWOOD AND VETERANS HALL (VETS) SEWE R LINER, SPECIFICATION NO . 91052 RECOMMENDATION S 1.Approve Plans and Specifications for the Johnson, Southwood, and Vets Sewer Liner Project , Specification No . 91052 . 2.Authorize staff to advertise for bids and authorize the City Manager to award the contract if th e lowest responsible bid for the Johnson, Southwood, and Vets Sewer Liner Project is within th e Engineer's Estimate of $268,000 . DISCUSSIO N Backgroun d Replacement of sewage collection pipes is an ongoing program to replace aging and deterioratin g infrastructure . This program has several objectives : 1) Ensure reliable removal of waste ; 2) Reduc e the need for emergency repairs ; 3) Reduce the need for preventive maintenance ; and 4) Ensur e uninterrupted sewage flow without health hazard or effluent leakage . This project will be rehabilitating existing sewer pipes in two locations . The first location extend s from the parking lot of the San Luis Obispo Veterans Hall down to the intersection of Palm an d Grove . The second location extends from Johnson Avenue down to the railroad tracks . All existin g pipes have been videotaped and identified by City staff as being at the end of its useful life an d candidates for the cure-in-place pipe (CIPP) polyester lining . Several advantages exist by using the CIPP in lieu of traditional open trench replacement methods . CIPP lining of the existing pipe will result in a reduced construction period as compared t o traditional open trench replacement construction, and it will be less disruptive to traffic, residents , and businesses . The proposed project will line 2,819 feet of existing sewer pipe . Also included in this project is the rehabilitation of fifteen sewer manholes . Manholes will b e rehabilitated with a polyurethane elastomer that will repair and protect the existing structures fro m the corrosive environment of the sewer system . Experience and Reference Requirement s The CIPP installation process for sewerline rehabilitation has many advantages in this situation an d it requires a contractor with specific experience and expertise to complete this work . A contracto r with limited CIPP installation experience could damage the sewer system, cause sewage spills, an d increase public inconvenience during the installation process . Johnson, Southwood, and Vets Sewer Liner Project, Specification No . 91052 Page 2 For these reasons, staff is planning to request the contractors to submit references documenting thei r experience . To comply with a recent legal decision, staff will be using a responsibility review t o determine that experience requirements have been met . Public Works staff will be working with th e City Attorney's office to ensure proper protocols are used . Staff is requesting the Director of Publi c Works be authorized to complete responsibility / qualification hearings in order to determine if th e lowest responsive bid was submitted by a responsible contractor capable of completing thi s specialized work . The hearings will allow any contractor initially determined by the projec t manager to not have the necessary experience, to provide information to the Director as to why thei r experience is adequate before a final recommendation for award is made . CONCURRENCE S This project is exempt from environmental review since it is a maintenance and replacement projec t and a Notice of Exemption has been filed through the Community Development Department . FISCAL IMPAC T This project is identified in the 2011-13 Financial Plan, Appendix B, on page 3-92 as part of th e approved projects pending construction and the 2011-12 project list .
