Elevated Tank #7 Rehabilitation Engineering - Proposal
History
The Village of Orland Park requested proposals from Village pre-qualified engineering firms to perform an evaluation of Elevated Tank #7 and provide recommendations and oversight for upgrades and paint restoration. Elevated Tank #7 is a spheroid style tank with 300,000 gallon total capacity, located at 13600 Cherry Lane. It was built in 1977 by Chicago Bridge and Iron Works (CBI).

Staff recommends, based upon the condition of the tank, for it to be the second of seven towers for rehabilitation.
The proposals were required to include the following services in their price:
- a thorough evaluation of the tank noting deficiencies
- provide recommendations for improvements
- 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
- coordination and status meetings with village staff
The selected engineering firm will also be required to work with Village staff to coordinate the removal of all cellular, phone and radio equipment during the restoration process and the reinstallation of the communication equipment after all modifications and paint restorations are completed.
Within the bell (bottom portion of the tank) there is a very small room which is only able to house a portion of the electronic equipment for the Village-owned antennas and controls. The remaining equipment is in an unheated space, subject to temperature extremes. Current Village initiatives are exploring opportunities to incorporate new technologies inside the tank utilizing a combination of wireless and fiber optic technologies. The introduction of this technology would improve emergency communications, decrease dependency of outside carriers and provi...
