Mercedes-Benz Stadium officials say that the one-of-a-kind retractable roof on Atlanta’s $1.5 billion sports venue is finished, about 11 months after the building opened to the public.

Officials announced that the general public will be able to see the roof in action on Sunday (July 29) before the National Football League’s Atlanta Falcons take the field for practice.

Mercedes-Benz Stadium

Mercedes-Benz Stadium officials say that the one-of-a-kind retractable roof on Atlanta’s $1.5 billion sports venue is finished, about 11 months after the building opened to the public.

The roof is supposed to open and close in an aperture motion, fully automated, in 12 minutes, and was a feat that caused multiple construction delays. As a result of those delays, the roof wasn’t completely ready by August 2017, when the stadium saw its first event. In fact, the roof was only open for three events over the past year—one Falcons game and two Major League Soccer Atlanta United games.

The Roof

The petaled roof caused multiple construction delays throughout the last year of construction, pushing the stadium’s opening date from March 1, to June 1, to July 30, to finally Aug. 26.

From the start, officials noted that structure of the roof is the first of its kind and consists of eight metal panels—or petals—that are to open simultaneously in around 10 minutes. It was designed by international architecture and engineering firm HOK (St. Louis, Missouri), in collaboration with tvsdesign, Goode Van Slyke Architecture and Stanley Beaman & Sears.

“Our roof is one of the marquee design elements of our stadium,” said Scott Jenkins, the stadium’s general manager and chairman of the Green Sports Alliance.

“Inspired by the oculus in the ancient Roman Pantheon, the eight-petal roof opens and closes like the aperture of a camera and is a major shift from the kinetic roofs of past sports facilities. The petals are clad with clear ETFE fabric so that even in the closed position you have natural light coming through and the sensation of an open-air stadium.”

Underneath the ETFE are eight 200-foot-long, 500-ton panels that are set on top of bogies, or mechanisms that sit along separate, motorized tracks, which are attached to the 18,000-ton fixed portion of the roof. When the roof opens, all petals move along their tracks simultaneously and give the illusion that they’re rotating like a camera lens.
