Flow Analysis and Design of Sixth Avenue Sewer Project March 5, 2013 Page 1 of 3 DATE: March 5, 2013 TO: Honorable Mayor and City Council FROM: Tom Tait, Public Works Services Director Ken Herman, Deputy Public Works Services Director Prepared by: Mark Rynkiewicz, Associate Civil Engineer SUBJECT: AUTHORIZE AND DIRECT THE CITY MANAGER TO EXECUTE A PROFESSIONAL SERVICES AGREEMENT WITH CIVILTEC ENGINEERING INC. FOR FLOW ANALYSIS AND DESIGN OF SIXTH AVENUE SEWER PROJECT IN THE AMOUNT OF $23,320 Recommendation: Approve SUMMARY The Public Works Services Department recently solicited proposals for a Professional Services Agreement (PSA) for flow analysis and design of a 10-inch sewer pipe on Sixth Avenue. Following a review and evaluation of the proposals received, Civiltec Engineering Inc. was determined to have the best proposal. Therefore, it is recommended that the City Council authorize the City Manager to execute a PSA with Civiltec Engineering Inc. for the flow analysis and design of a 10-inch sewer pipe on Sixth Avenue in the amount of $23,320. BACKGROUND The City’s Sewer Master Plan Update addresses the needs of the City’s sewer system through the calendar year 2026 and establishes the maintenance and improvement framework the City uses to make decisions on future operational goals and capital improvement projects. As part of the Sewer Master Plan Update, hydraulic modeling of the City’s sewer system was performed to determine the performance of the sanitary sewer system and the results were analyzed for average day flows, peak flows, and wet weather flows. The results of this modeling identified the sewer pipe at Sixth Avenue between Verner Circle and Live Oak Avenue to be flowing above capacity and to be deficient for peak estimated flows (Exhibit A). This assessment has been confirmed by the City’s sewer maintenance personnel. The Sewer Master Plan recommends that the sewer pipe in Flow Analysis and Design of Sixth Avenue Sewer Project March 5, 2013 Page 2 of 3 this section be replaced with a larger pipe in order to increase the capacity of the pipe and eliminate the possibility of a sewer backup. The Sewer Master Plan Update recommends that design of a sewer pipe project be scheduled in one fiscal year and the construction of the project be done in the following fiscal year. This is done to ensure that sufficient funds are available in the Sewer System Reserve Fund. As a result, construction of the 10-inch sewer pipe is scheduled to be completed in Fiscal Year 2013-14. DISCUSSION Request for Proposals were sent to various firms known to be experts in sewer design and analysis for this project. Request for proposals were sent to five sewer design firms, and advertised in the local newspaper. A total of two proposals were received, reviewed, evaluated, and ranked by staff with the following results: Consultant Location Proposal Rating Fee 1. Civiltec Engineering Monrovia 97% $ 23,320 2. SA Associates Arcadia 74% $ 58,000 In accordance with the Arcadia Municipal Code, the evaluation of proposals was based on demonstrated competence and qualifications necessary for the satisfactory performance of the professional services required to be performed at fair and reasonable prices. Based on this review and interviews with both firms, Civiltec Engineering Inc. was considered the most qualified to do the work because they demonstrated specific experience in providing similar services to other municipalities with their cost significantly below other competitors. Therefore, it is recommended that the City Council authorize the City Manager to enter into a PSA with Civiltec Engineering Inc. for the flow analysis and design of a 10-inch sewer pipe on Sixth Avenue in the amount of $23,320. FISCAL IMPACT The proposed cost of the design and analysis will be $23,320. Funds in the amount of $50,000 have been budgeted in the Fiscal Year 2012-13 Capital Improvement Program for the design of a 10-inch sewer pipe on Sixth Avenue.
