Honorable Mayor and Members of the City Council: BACKGROUND The five-year Capital Improvement Program (2001/2002 thru 2005/06) has identified PS-6 for wet well and pump replacement with an annual allocation budget amount of $500,000 per year. To date, $2,236,875 has been set aside for pump station renovation/replacement. The existing sanitary pump station S-6 was constructed in the 1960's and is located at the northeast corner of the intersection of the Arroyo Mocho and Alamo Canal, adjacent to the West Las Positas Boulevard over-crossing of Interstate 1-680. This pump station consists of a "metal can" dry well configuration pumping from an adjacent concrete wet well into a force main that runs northerly to the Dublin San Ramon Services District (DSRSD) treatment plant. All pumping and electrical systems, along with the pump station building, are in poor condition and the pumps are currently operating with capacity problems under dry weather and wet weather flow conditions. Specialty engineering services from a design consultant are needed to evaluate the existing operating criteria, capacities, and operational constraints in order to determine what is necessary to keep the existing pump station operational for the next 2-3 years until a new pump station can be designed and constructed. As part of this contract, the consultant will also develop a preliminary design report identifying various replacement pump station design alternatives and preliminary cost estimates for each. The design report will contain a recommendation to the City as to the preferred design alternative. Final construction plans and specifications for a replacement pump station are not included as part of this contract. After reviewing the alternative analysis/pre-design report that will be submitted by the consultant, staff will prepare a Budget Option Plan for the new S-6 pump station design and construction. Detailed plans and specifications of the selected alternative will then be prepared by a consultant under a separate contract for construction of the new S-6 pump station. Because of the specialized pump station renovation and engineering experience required for this project, a consulting firm is necessary to perform the condition assessment and alternative evaluations for the new pump station. Using the City's consultant database, and responding to letters of interest submitted by consultants, a total of sixteen firms were invited to submit proposals. Three (3) firms responded to our request. After review and evaluation of these proposals by City staff, BKF was determined to be the most qualified consultant. Parameters used for the evaluation of the proposals and interviews included presentation, project understanding, project approach, members of the project team and previous experience with similar projects. Previous work performed by BKF was verified to be satisfactory. Page 2 on
