- Remote Transmitter/Receiver Facilities
Burns & McDonnell provided project management, architectural, civil, structural, electrical and mechanical design services for the development of two new remote transmitter/receiver (RTR) facilities in the South Airfield at O'Hare International Airport. The multidisciplined project for the O'Hare Modernization Program includes four antenna towers and an equipment shelter at each site. The facilities supplement the air and ground communications between aircraft and the Air Traffic Control Tower. Approximately 8.5 miles of new 12-strand single mode fiber optic cable was installed through existing and new duct bank infrastructure to provide connectivity between the tower and the RTR facilities. The project also included the construction of approximately 4,000 linear feet of new reinforced concrete-encased and jacked steel casing duct bank. All cable installation and duct bank construction was designed for completion in active airfield conditions with no impact to airport operations.
A large drainage ditch, approximately 30 feet deep, between the RTR R site and the ATCT, was to be backfilled after the duct banks were complete. In order to install the duct bank across the ditch at an elevation that would not be excessively deep and difficult to maintain, concrete foundations were installed in the ditch side slopes and an 80-foot structural steel casing was built across the span, above the flood plain elevation. The design also had to account for thermal expansion of the casing before backfilling.
