Title
Authorizing the City Manager to execute a Change Order with McDonald Municipal and Industrial for the Surface Water Treatment Plant Emergency Generator in the amount of $58,800 for the installation of the temporary generator at the Surface Water Treatment Plant.
Summary
As has been noted on previous City Council items, the Surface Water Treatment Plant and Lake Pump Station currently do not have backup power supply in the event of an extended power failure as was experienced from February 15, 2021 to February 17, 2021. This creates a significant risk for the City’s Public Water System as the plant produces most of the water that is used within the City. Due to this risk and the need to make the City's water system more resilient in the event of an emergency, the City Council approved a professional services agreement with Gupta and Associates, Inc. on September 22, 2020 to design the emergency generator power system.
As the generator for the Surface Water Treatment Plant has a long lead time of an estimated 34 weeks from time of order, City Council approved the rental of a temporary generator for the Surface Water Treatment Plant at the December 14th City Council meeting to provide emergency power until the permanent generator can be installed.
In order to facilitate the installation of the temporary generator, we will need to install a manual transfer switch and procedures for how to transfer power if needed to the temporary generator if we lose power at the facility. After reviewing the red-line drawings to hook up the temporary generator, it was determined that the best course of action was to have McDonald Municipal and Industrial perform the work as they were already familiar with the switchgear and are already mobilized to the site.
As the temporary generators and the related installation will bring this project over the original budget, if there isn't savings in other areas to fund the difference, a future budget amendment will be needed.
