BACKGROUND The existing Walnut Street Interceptor was constructed circa 1970. It is a 48 -inch diameter gravity sewer main that conveys the flows from the west side of U.S. Highway 101 to the Maple Street Pump Station located east of the highway. All wastewater generated west of U.S. Highway 101 is carried through this single pipeline to the Maple Street Pump Station and subsequently pumped into the South Bayside System Authority's (SBSA) conveyance system for treatment at the SBSA's wastewater plant. The Walnut Street Sewer Interceptor Project is necessary to ensure the reliability of the wastewater collection system. This existing pipeline will remain in service and a new pipeline will be constructed to improve the reliability the sewer system. Council awarded the preliminary engineering design for the project on August 23, 2010 to RMC Water and Environment of San Jose, CA. The consultant completed the evaluation of the alignment options, trenchless crossing alternatives and probable construction cost. The results of the evaluation were summarized in a technical memorandum. ANALYSIS In September 2013, staff solicited Requests for Proposal (RFP) from sixteen civil engineering consultants. Based on review of the proposals and interviews with firms, Kennedy /Jenks Consultants was deemed to be the best qualified firm for this project as their staff and project team demonstrated the most " trenchless" design /technology experience and provided an effective labor of effort to complete the project.
