Hunt Construction Group, Inc.


Cardinals Stadium, completed in 2006, is the home of the National Football League's Arizona Cardinals and the annual Fiesta Bowl. The stadium features a retractable roof that is supported by two parallel 700-foot-long "super trusses" weighing approximately 11 million pounds. The trusses are supported by 160-foot-tall "super columns."


WJE designed and installed a state-of-the-art instrumentation and monitoring system to achieve the project objectives. Key elements included the following:

Installation of more than eighty strain gages, displacement gages, and thermocouples on the trusses during construction and monitoring of data collected from four networked data acquisition units

Wireless collection of survey data for sixty-eight monitoring points as measured by two remote survey stations during the roof lift

Utilization of a local area wireless network to connect six data acquisition systems for broadcast of acquired data to lift participants

Implementation of a centralized database collection system to allow access and management of data for multiple users simultaneously

Development of software capable of processing and graphing real-time and historical data in a user-friendly interface
