A001 - Council Action Form dated February 24, 2026
ITEM #:18 DATE:02-24-26 DEPT:W&PC SUBJECT:WATER POLLUTION CONTROL FACILITY NUTRIENT REDUCTION MODIFICATIONS PHASE 1 PROJECT - CHANGE ORDER #8 COUNCIL ACTION FORM BACKGROUND: On August 13, 2024, City Council awarded a contract to Woodruff Construction for modifications to the Water Pollution Control Facility (WPCF) in the amount of $53,370,000. These modifications are the first of two construction phases that will ultimately enable the facility to achieve the goals of the Iowa Nutrient Reduction Strategy. As is common with large construction contracts, this project has required multiple change orders. To date, seven change orders have been approved for a combined total reduction in the contract price of $157,234.77. Details regarding the scope and amounts of each change order are outlined below in Table 1. An eighth change order has been prepared and is ready for Council approval. It includes six individual changes to the construction documents. The most notable item is a cost difference credit for work that was previously approved under Change Order #6. In that change order, Council approved an allowance not to exceed $115,247.35 to relocate a water line that was found to be in a different location than anticipated. The work was done on a time-and-material basis that ultimately totaled only $79,597. Item 8c on this change order is to release the $35,650.35 that was not used. Item 8b on this change order is for changes to exterior door hardware. The style specified was not the style staff was anticipating. The engineer has agreed to provide a credit on their next invoice to offset the cost of the contract change ($5,499.33). Other items in this change order include: relocating an overhead door in the maintenance garage; adding an automatic door opener to the exterior door leading into the mud room; adding corner guards throughout the administration building; and substituting a different style of programmable logic controller. Combined, the total of all six items in Change Order No. 8 is an increase to the construction contract of $3,841.91. The additional offsetting credit from the engineer for the door hardware results in a net decrease to the overall project cost of $1,657.42. Table 1: Change Order Summary Change Order #1 Credit for Enviromix, fire alarms, canopy; reroute gate power circuit; expansion joint changes.

It should be noted that the SRF program is a reimbursement program, meaning that the City first spends the money, then the program reimburses for eligible expenses. This method ensures the City will only borrow for expenses the City Council has authorized and are necessary to complete the project, thus minimizing interest expense associated with the improvements. ALTERNATIVES: 1. Approve Change Order #8 to the contract with Woodruff Construction for the Water Pollution Control Facility Nutrient Reduction Modifications Phase 1 Project in the amount of $3,841.91. 2. Do not approve the change order. This would reject the recommended changes to the contract documents. CITY MANAGER'S RECOMMENDED ACTION: The proposed changes are to maintain and improve the reliability and function of the Water Pollution Control Plant Modifications. The consultant, contractor, and City staff have worked closely together to come up with reasonable, cost-effective recommendations. Therefore, it is the recommendation of the City Manager that the City Council adopt Alternative 1 as described above.
