Title
Elevated Tank #6 & Tank #4 Rehabilitation Engineering - Proposal
History
The Village of Orland Park requested proposals from Village pre-qualified engineering firms to perform an evaluation of Elevated Tank #6 and Tank #4 to provide recommendations for upgrades and paint restoration.
Elevated Tank #6 is a spheroid style tank with a 750,000-gallon total capacity, located at 9701 W. 131st Street. It was built in 1995 by Chicago Bridge and Iron Works (CBI). The tank has not been painted since it was put in service. Elevated Tank #4 is a spheroid style tank with a 300,000-gallon capacity, located at 14605 S. 88th Avenue. It was built in 1971 by CBI.
Both tanks will be rehabilitated in 2022. The proposals were required to include the following services in their price:
- a thorough evaluation of the tank noting deficiencies;
- recommendations for improvements;
- costs for improvements;
- construction and rehabilitation schedule;
- evaluation, recommendation, and provision of a cost estimate for a combination railing and antenna mounting system;
- separation of electrical services; and
- 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 of Tank #4 (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, decreas...
