The Atlanta Falcons have released the latest timelapse video of construction work on the Mercedes-Benz Stadium as it nears completion.
Earlier this month, the HOK-designed Mercedes-Benz Stadium’s one-of-a-kind roof was closed for the first time.
The stadium’s roof is made up of 27,500 tons of steel, 3,500 tons of which make up the roof petals.
The roof may appear to rotate open but it’s an optical illusion. The roof opens by the movement of eight “petals” that slide open in a straight line.
Each of the moving petals cantilever approximately 200 feet inwards towards the centre of the stadium and provide a roof covering when the petals are in the closed position.
The moveable petal structures are powered by eight mechanised “bogies” which drive the petals along an inner rail and are attached to the outer uplift rail by six roller mechanisms.
In the closed position the petals lock together to form a water tight seal. Each petal structure is clad with air-inflated ETFE pillows.
ETFE is a highly durable, lightweight fabric that is translucent, allowing for a light filled stadium, even when moveable petals are in the closed position.
Mercedes-Benz Stadium is designed with functionality and flexibility in mind. The seating capacity can be expanded to up to 75,000 to play host to a potential future Super Bowl or FIFA World Cup, or to up to 83,000 for other events such as the NCAA Final Four.
Alternatively, by utilising an innovative mechanised curtaining system for the stadium’s mid and upper bowls, capacity for events like family shows, concerts and Atlanta United (MLS) games can be reduced to optimise the appropriate event setting.
