(Public Works 602)
Body
To: Honorable Mayor and Members of the City Council
From: David L. Rudat, Interim City Manager
EXECUTIVE SUMMARY
The City issued a Request for Proposal 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. A second amendment to the contract is needed for engineering design and construction support services for Cyclic Sewer Rehabilitation Project, Phase 16 (Exhibit 3).
BACKGROUND
The City of Alameda 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 5 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 5 replaces approximately 2.9 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 2017 Sewer System Management Plan and adopted Capital Improvement Program.
On July 1, 2017, the City Council authorized the first amendment to agreement to extend the term of the contract only for the design of cyclic sewer rehabilitation project, phase 14 (Exhibit 2).
DISCUSSION
A second amendment to the contract is needed for engineering design and construction support services for cyclic sewer rehabilitation project, phase 16, consisting of approximately 2.9 miles of sewer main (Year 5 of the SMP). The budget for these services is $394,390. 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:
• 9th Street, between Pacific Avenue and Buena Vista Avenue
• Bay Street, between Pacific Avenue and end
• Centennial Avenue, end to end
• Clement Avenue, between Schiller Street and Lafayette Street
• Taylor Avenue and Fourth Street
• Bay Street easement sewer
• Mariner Square Loop easement sewer
• Grand Street, between Fortmann Way and end
• Grand Street and Shoreline Drive
• Lafayette Street, between Alameda Avenue and Clinton Avenue
• Lincoln Avenue, between Eighth Street and St. Charles Street
• Mariner Square Loop, between Mariner Square Loop and Webster Street
• Pacific Avenue, between Webster Street and Constitution Way
• Robert Crown Memorial State Beach
• San Antonio Avenue, between St. Charles Street and end
• San Antonio Avenue, between Morton Street and Chestnut Street
• Sand Beach Place, between Sand Beach Road and Harbor Light Road
• Santa Clara Avenue, between Paru Street and Lafayette Street
• Santa Clara Avenue, between Morton Street and Benton Street
• Taylor Avenue and Eighth Street
The principal goal of the sewer rehabilitation program is to improve the health and safety of the residents of Alameda 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 16, will be designed over Fiscal Year 2018/2019 with construction starting in July 2019.
