HEAD f^T^T CITY ATTY. @& CITY MGR. U/"^ RECOMMENDED ACTION: Adopt Resolution No. 2008-225 accepting bids and awarding the contract to SOCAL Pacific Construction Corporation for the Vista/Carlsbad Interceptor Sewer, Reaches VC13-VC15 Manhole Rehabilitation, Project No. 3949. ITEM EXPLANATION: The Vista/Carlsbad (VIC) Interceptor Sewer was constructed in 1965 and is jointly-owned by the City of Vista and the City of Carlsbad. The alignment, approximately eight miles in length within the City of Carlsbad, extends from just west of the intersection of College Boulevard and Highway 78 to the Encina Water Pollution Control Facility (Encina). The V/C Interceptor Sewer is divided into reaches numbered VC1 through VC16. Reaches VC1 through VC11A have been replaced or rehabilitated in recent years, with the exception of the Buena Vista Force Main (Reach VC4), which is currently in design for replacement. The City has recently completed a study to investigate alternatives and develop a design concept to replace Reaches VC11B through VC15. The preferred design concept includes replacement of the trestle bridge across Agua Hedionda Lagoon with a new concrete bridge (VC11B), and construction of a new lift station approximately 50-feet east of the current facility with a new force main (VC12). The pipeline in Reaches VC13 through VC15 is in good condition but undersized for future flows. The preferred design for these lower reaches includes constructing a parallel gravity pipeline and continuing to utilize the existing Reaches VC13 through VC15. Together the parallel pipelines will provide capacity for the ultimate future flows. The existing gravity interceptor sewer will also maintain existing sewer connections. While the PVC lined pipeline was found to be in good condition, a total of 27 manholes in Reaches VC13 through VC15 are severely corroded and require immediate attention. In consideration of the significant environmental permitting and coordination issues for the bridge, lift station and new pipeline, construction of the new improvements is expected to occur no earlier than January 2010. The manhole rehabilitation portion of the project has, therefore, been separated into its own construction contract in an effort to expedite the improvements and eliminate the risk of a manhole failure. On May 6, 2008, through the adoption of Resolution No. 2008-130, the Carlsbad City Council approved plans and specifications and authorized the City Clerk to advertise to receive bids for the Vista/Carlsbad Interceptor Sewer, Reaches VC13-VC15 Manhole Rehabilitation, Project No. 3949.
