Item:Approve Change Order #1 to the 2025 Sanitary Sewer Lining Program
COUNCIL ACTION REQUESTED
Council is requested to approve Change Order #1 to the 2025 Sanitary Sewer Lining Program which makes two
minor modifications to the project scope.
BACKGROUND INFORMATION
During final field preparations for CIPP lining, Hydro-Klean and City staff identified two modifications that will
enhance the project scope:
•Forest Street Sewer Segment –Adding an additional segment of 8-inch sanitary sewer lining on Forest
Street between 6th Street and 7th Street. This section was found to be in similar deteriorated condition
to adjacent segments already included in the project.
•Storm Sewer Transition Liner –Installing a transition liner at a sewer location where the pipe diameter
changes from 18 inches to 24 inches at a drainage structure.Without this transition liner, the lining
planned in this pipe may be compromised in quality.
FINANCIAL IMPACT
If approved by Council, the cost to add these enhancements to the project is $11,290.50.
This added cost still leaves the contract with sufficient contingency for other possible unforeseen costs within the
total $580,000 project budget.A change order summary is provided below:
