CITY COUNCIL AGENDA ITEM 6D STAFF ORIGINATOR: Diane Hankee PE, City Engineer MEETING DATE: July 27, 2020 TOPIC: Consider Resolution No. 20-86, Approving Change Order No. 1, Water Tower No. 3 Project VOTE REQUIRED: 3/5 INTRODUCTION Staff is requesting council approval of Change Order No. 1 (CO 1) for the Water Tower No. 3 Project. BACKGROUND On August 25, 2019, the City Council awarded the bid for the Water Tower No. 3 Project to Landmark Structures in the amount of $4,067,000.00. Construction of the project has been on- going since that time. The proposed CO 1 is to add a flowmeter on the altitude valve and includes associated electrical wiring and SCADA programming. The Minnesota Department of Health (MDH) required this flow meter to confirm proof of flow into the water tower whenever the chlorine feed system at the base of the tower is operating. MDH came-up with this requirement after the project had already bid. This work includes the electrical integration of the flow meter and the integrator’s work to update the City’s SCADA system. The system will monitor the chlorine feed pump if no proof of flow is confirmed from the flow meter. There was also a deduct on the project to reduce the size of the overflow pipe from a 16 inch to a 12 inch diameter. The net amount of Order No. 1 is in the amount $5,560.00. The Water Tower No. 3 Project contract with Landmark Structures with Change Order No. 1 would be increased to $4,072,560.00. The project is funded through the City’s trunk utility fund. The completion date for this project is August of 2021. RECOMMENDATION Staff is recommending approval of Resolution No. 20-86 for Change Order No. 1 in the amount of $5,560.00 for the Water Tower No. 3 Project. ATTACHMENTS 1. Resolution 20-86 2.
