Make It Move

We engineered the world’s first domed sports stadium, the Astrodome, and set in motion a new era in sports venues. Nearly 50 years later, we’re doing it again—literally.

The Arizona Cardinals are a long way from their original home in Chicago. And their new stadium in Glendale, a satellite of Phoenix, has gone way beyond anything else in the National Football League (NFL). As the design engineer Larry Griffis (President of our Structural Engineering Group) explains, “It has taken technology to another level” – “transporter” technology, that is.

Inaugurated for the 2006 NFL season, Arizona Cardinals Stadium is the most structurally kinetic stadium in the country—and our third (with more on the way). Its retractable roof opens and closes, while the playing field sits in a 234-foot wide by 400-foot long tray that can be rolled outdoors during the off-season to maintain the natural grass turf. The combination of retractable roof and movable field is a first. And there are others.

Designed to resemble a barrel cactus, the $450-million, 65,000-seat stadium’s geometry dictated a sloping roof—another first for a retractable roof. We accomplished this with a bi-parting, twin panel design. The panels meet above the 50-yard line, at the peak of the roof’s arc, courtesy of wheeled transporters riding on crane rails. The roof assembly’s sideline trusses are nearly 700 feet long, making them the longest clear span of any retractable roof. And then there was the roof lift, the heaviest on record in North America.

All in all, the structure masters the most complex kinetic design of any stadium built in America to date.
