TRC Worldwide Engineering, Inc. provided precast concrete engineering services for this multi-purpose facility. The University of Phoenix Stadium was designed with the ability to host football, basketball, soccer, concerts, consumer shows, motorsports, rodeos and corporate events. The primary tenants include NFL's Arizona Cardinals and the Annual Tostitos Fiesta Bowl. The 63,400-seat stadium (expandable to 72,200) opened on August 1, 2006 after three years of construction.
The stadium was the first in North America with both a retractable roof and retractable field. There are six levels in the stadium: the field (or service) level; the main concourse, the club level, the suite level; the upper concourse and the mechanical level.
The amount of concrete used on the stadium is equal to 900 miles of sidewalk, the distance between Phoenix and San Francisco.
