PURPOSE:
To obtain City Council approval to attain a professional engineering services agreement with Engineering Enterprises, Inc., Sugar Grove, IL (EEI) for the design and construction observation of the Indian Trail Elevated Tank Site Improvements project for the Water Production Division.
BACKGROUND:
The 1.5 million gallon Indian Trail Elevated Tank, located at 1325 West Indian Trail, provides potable water distribution system pressure and storage capacity.

The recoating of the tank was completed in summer/fall 2014, and the contractor is currently demobilizing from the site.

Unfortunately, the site is small and performing the tank recoating work at the same time as the numerous site improvements would have proved inefficient, costly, and potentially unsafe. The specialized painting contractor necessary to perform the blasting and painting work would not have been knowledgeable with the site improvement work and vice versa. Thus, it became apparent that splitting the work up into two separate projects was not only necessary, but also prudent.
As the painting work has been completed, the desig...
