A new video has been released by Atlanta Mercedes Benz Stadium displaying -for the first time- the closure of the stadium’s exceptional Hi-Tech retractile aperture-like roof. The 8 huge ETFE-clad panels that make up the roof resemble the petals of a flower. They glide on tracks to meet eventually at one point in the center, closing up the whole thing. The process of opening and closing, which is much similar to a camera lens aperture, is expected to take about 8 minutes upon its effective operation.
Although the roof is entirely constructed, according to the Atlanta Journal Constitution, the system has not been programmed yet, and so the roof will remain closed during the inaugural match between the NFL’s Atlanta Falcons and Arizona Cardinals on the 26th of August.
360 Architecture firm (acquired by HOK in 2015) designed the stadium to host a variety of sports and music events like the Super Bowl and the NCAA Final Four concerts. The project, that was first publicized near the beginning of 2015, has an area of 2 million square feet with a cost nearing $1.5 billion.
Check out the following construction time span and drone filming videos of the project:
