Resolution to Approve Amendment No. 1 to the Professional Services Agreement with OHM Advisors for General Civil Engineering and Surveying Services (Additional $900,000.00 for a Contract Total of $1,650,000.00)
Memorandum
This resolution requests approval of Amendment No. 1 to the professional services agreement for General Civil Engineering and Surveying Services with OHM Advisors (OHM). City Council approved a professional services agreement for $750,000.00 with OHM on August 7, 2023, as part of Resolution No. R-23-277.
Under the current contract, OHM has provided engineering services for a variety of projects. They have demonstrated themselves to be experienced in a wide range of disciplines, and they are responsive and cost effective in meeting the diverse needs on complex engineering tasks.
At the City’s request, OHM was commissioned by the University of Michigan (UofM) to evaluate impacts to the City’s sanitary sewer system as a result of the proposed UofM dorm developments in south campus. Results from this effort indicated a relief sewer will be needed to accommodate the flows from the proposed dorms. This sewer project will also benefit the City as a whole, adding sewer capacity for future growth within the sewer shed. The City created a capital project for this effort, titled the High-Level Trunkline Sewer Capacity Improvements Project.
OHM has completed their preliminary design efforts and, after evaluating several alternatives, a proposed route for the relief sewer was selected along First Street from Washington Street to Miller Avenue. The engineering design for this project must now commence in order to coincide with the expedited timeline of the first phase of the dorm project (August 2026).
Due to the expedited schedule, issuing a Request for Proposal for this design work is not feasible within the required timeframe. Considering OHM’s extensive knowledge of the project and the sanitary sewer analysis already performed, staff is recommended extending the existing contract with OHM to perform these design services. OHM has done similar work for the City in the past, and staff is comfortable with their knowledge and expertise.
UofM, who is funding 100% of the design and construction of the project, agrees with using OHM to design the project. A cost sharing agreement with UofM is in the process of being formalized and will be submitted to Council when it has been finalized.
OHM complies with the City’s Non-Discrimination and Living Wage ordinances.
Budget/Fiscal Impact: The proposed amendment will be for use on the High-Level Trunkline Sewer Capacity Improvements Project, which will be fully funded by the University of Michigan. The costs will be incurred by the Sewage Disposal System Capital Budget and reimbursed by the University of Michigan.
