Elevated Tank #5 Rehabilitation Engineering - Proposals
History
The Village of Orland Park requested proposals from qualified engineering firms to perform an evaluation of Elevated Tank #5 and provide recommendations and oversight for upgrades and paint restoration.

It was the expectation of Public Works that the selected firm will include the following in their proposal price:

- provide costs for improvements
- provide construction and rehabilitation schedule
- evaluate, recommend and provide a cost estimate for a combination railing and antenna mounting system
- separation of electrical services
- provide a minimum of three (3) exterior paint schemes incorporating the Village’s new logo and branding
- coordination and status meetings with village staff
Below are more detail of the improvements and oversight requested of the firms.
