Agenda Item:
Update on the Water Resource Recovery Facility (WRRF) Disinfection and Digester Project.
Recommendation/Action(s):
Motion approving Change Orders 1-13 for the Disinfection and Digester Project at the Water Resource Recovery Facility (WRRF).
Summary:
A construction contract for this project was awarded to Rice Lake Construction Group on May 13, 2024. Work began shortly thereafter and is currently anticipated to be completed by mid-2027. As of the beginning of September 2025, approximately 1/3 of the construction contract has been completed ($28,390,528 of $83,741,911).
As of September 1st, 13 change orders have been approved for a net total of $19,310. This equates to 0.02% of the original contract amount. Mankato City Code allows the City Manager to approve change orders up to 5% of the original contract amount ($4,186,130) with a condition that such change orders be reported to the City Council. A tabulation of the 13 approved change order is attached.
The total project cost, including construction, contingencies and engineering, is just under $94 million. Initial project costs are proposed to be financed with a loan from the Public Facilities Authority (PFA) which will be repaid with a combination of State/Federal grants (approx. 50%) and local utility funds (approx. 50%). As can be seen in the attached Disinfection and Digestion Cost graph, the project is on schedule and within budget.
