File Number: 24-033 through this contract. The required efforts to collaborate with sister agencies owning utilities within the project vicinity led to the decision to divide the project into two phases. Phase 1 focused on the design and construction of the SE Line, a project that was completed in January 2023. Instead of replacing the SE Line, it was rehabilitated using a PVC lining of the pipe’s interior, a strategic measure that eliminated the need for excavating potentially contaminated soil that minimized any harmful or negative environmental effects from disturbing potentially contaminated soil and mitigating significant disposal costs related to the same. Moving forward, Phase 2 will concentrate on the Davis Street Manhole Replacement. This phase involves replacing the sanitary sewer manhole on Davis Street situated adjacent to the WPCP. This phase also includes the realignment of a 30-inch by 33-inch diameter sewer pipe entering the plant from the manhole. These sewer lines are essential for transporting influent to the plant headworks for treatment prior to discharge. Analysis On April 20, 2020, by Resolution No. 2020-035, the City Council approved a consulting services agreement with Lee & Ro for the design of the Secondary Effluent Line Replacement and Davis Street Manhole Replacement project. The agreement also granted the authority for amendments, with a maximum limit of 15% of the original agreement amount. However, various challenges, including disruptions caused by the COVID-19 pandemic, significant staff turnover and less-than-optimal collaboration from sister agencies with facilities within the project site led to extensive extensions of the contract term. This extension has resulted in increased costs to both the City and the consultant. Initially intended for the rehabilitation of the Davis Street Manhole, a detailed analysis during the design phase revealed that replacement was necessary due to severe deterioration, bringing the manhole to the brink of failure. This shift in the repair strategy required collaboration with sister agencies that owned utilities in the vicinity. To bring this project phase to successful completion, staff recommends that the City Council authorize an increase to the change order cap from 15% to 40%, which is approximately $90,495. Upon City Council approval of the increase, Lee & Ro will be able to sustain its engagement on the project, successfully conclude the design phase and offer construction support for the Davis Street Manhole Replacement. Lee & Ro’s expertise and in-depth understanding of the project’s challenges uniquely position it to navigate the complexities efficiently and bring the project to its successful conclusion. Failure to approve the increase to the amendment cap may impede the expeditious completion of the project, posing a risk to its timely completion and consequent failure of the manhole structure.
