EXECUTIVE SUMMARY
The City of Alameda (City) issued a Request for Proposal (RFP) on November 13, 2015, for engineering design and construction support services for Cyclic Sewer Rehabilitation Project, Phase 13. Nute Engineering was selected as the most suitable firm to perform these services and was awarded the contract on July 20, 2016 (Exhibit 1). The contract allows for an annual extension for up to four additional years, with each extension coming before City Council for approval. On July 1, 2017, City Council authorized the first amendment to extend the term of the contract only for the design of Cyclic Sewer Rehabilitation Project, Phase 14 (Exhibit 2). On October 16, 2018, the City Council authorized the second amendment to agreement to extend the contract for engineering design and construction support for Cyclic Sewer Rehabilitation Project, Phase 16 (Exhibit 3). Staff is requesting a third amendment to the contract for engineering design and construction support services for Cyclic Sewer Rehabilitation Project, Phase 17 (Exhibit 4).
BACKGROUND
The City operates the local sanitary sewer collection system comprised of sewer pipes, pump stations, and other facilities. Some of this aging infrastructure has reached its life expectancy and requires rehabilitation. The work to be designed as part of this contract serves as Project Year 6 of the 20-Year Rehabilitation Program included in the City’s Sewer Master Plan (SMP), 2015. The SMP utilized information collected through maintenance, inspection, and monitoring activities to assess system condition and capacity. The results were used to identify and prioritize sewer system capital improvement needs in a 20-Year Rehabilitation Program structured to maintain compliance with the Consent Decree and be consistent with the City’s sewer rate structure.
Project Year 6 replaces approximately 3.2 miles of existing old and deteriorating sanitary sewer main. Completion of this work is required for compliance under the Final Consent Decree for Consolidated Case Nos. C09-00186-RS and C09-05684-RS, which requires the City to rehabilitate no less than 2.6 miles of sewer main and associated lower laterals and manholes per year, based on a cumulative total. This work is also consistent with and furthers the objectives of the City’s 2018 Sewer System Management Plan and adopted Capital Improvement Program.
DISCUSSION
A third amendment to the contract is needed for engineering design and construction support services for Cyclic Sewer Rehabilitation Project, Phase 17, consisting of approximately 3.2 miles of sewer main (Year 6 of the SMP). The cost for these services is $414,362. The location of the sanitary sewer mains in this project were prioritized for replacement based on condition and environmental consequences. The locations are as follows:
• Walnut Street, Clement Avenue to end
• Lincoln Avenue, between Walnut Street and Park Street
• Park Street, between Clinton Avenue and Central Avenue
• Park Avenue, between Central Avenue and Webb Avenue
• Eagle Avenue, between Broadway and Pearl Street
• Pearl Street, between Fernside Boulevard and Tilden Way
• Janis Court, Pearl Street to end
• Fernside Boulevard, between Cambridge Drive and Cornell Drive
• Fernside Boulevard, backyard of Harvard Drive to Moreland Drive
• Fremont Drive, between Northwood Drive and Fernside Boulevard
• Thompson Avenue, between Southwood Drive and High Street
• Haight Street, between Encinal Avenue and Santa Clara Avenue
• Jackson Street, between Court Street and Fountain Street
• Lincoln Avenue, between Versailles Avenue and Gibbons Drive
• Versailles Avenue, between Central Avenue and Lincoln Avenue
• Gibbons Drive, between backyard Santa Clara Avenue and Lincoln Avenue
• Santa Clara Avenue, between Versailles Avenue and Court Street
• Mound Street, between Jackson Street and Santa Clara Avenue
• Van Buren Street, between Versailles Avenue and Mound Street
• Van Buren Street, between Court Street and High Street
• Fountain Street, between Adams Street and Encinal Avenue
• East Shore Drive, between Liberty Avenue and Constance Circle
• Constant Circle, East Shore Drive to end
The principal goal of the sewer rehabilitation program is to improve the health and safety of the residents of the City by rehabilitating the sanitary sewer collection system, eliminating overflows, and reducing the amount of infiltration and inflow into the sewer system. It is expected that the Cyclic Sewer Rehabilitation Project, Phase 17, will be designed over Fiscal Year 2019-20 with construction starting in July 2020.
