Mercedes-Benz Stadium, Atlanta, Georgia, United States of America
Mercedes-Benz Stadium is a new 72,000-seat stadium being built in Atlanta, Georgia, US. The new stadium will host sporting events, such as National Football League and Major League Soccer games, and concerts.
Being developed by Georgia World Congress Center Authority, the $1.4bn new stadium will replace the Georgia Dome as the NFL Falcons' new home.
Construction on the stadium began in May 2014 and is scheduled for completion in June 2017.
Mercedes-Benz Stadium design details
With a built-up area of two million ft², the stadium is designed to be easily reconfigured to accommodate NFL and MSL games.
It features a retractable roof in the shape of a camera lens, which can be opened in less than ten minutes. The design of the roof is inspired by the shape of a falcon's wing, and consists of three-layered ethylene tetrafluoroethylene (ETFE) cushions cantilevered on eight retractable petals.
The roof opens to allow natural sunlight to enter the stadium, and closes to protect players and the audience during adverse weather conditions.
The stadium's façade will also feature ETFE materials, including a single ETFE skin supported by a cable net system.
Construction of the roof requires 135,000ft² of triple-layered ETFE pillows, an air inflation system and 165,000ft² of vertical single-layered ETFE film. ETFE was chosen for the roof due to its durability, aesthetic and sustainability.
The ETFE film is also UV-transparent, protecting it from being structurally weakened or discoloured from exposure to UV. The surface of the film is inert in nature, allowing it to resist airborne pollutants, dust and chemicals.
Facilities and technology used at the new stadium
The interior of the Mercedes-Benz stadium features a variety of seating options, including 190 luxury suites and 7,600 club seats. The stadium also features 24 bars and restaurants, including a technology lounge and a 100-yard bar.
The stadium will feature digital media platforms, including the world's largest 360° HD video halo board, which will provide targeted programmable content to fans.
The halo board features an LED display spanning 64,000ft². With a height of 58ft and a circumference of 1,075ft, the board will provide supplementary camera views and digital content for fans.
In addition to the halo display, the stadium will feature 12 other LED displays, which will provide live video and replays in club areas, and perimeter displays.
The stadium was designed by tvsDesign in collaboration with HOK, Goode Van Slyke Architecture and Stanley Beaman & Sears, while Buro Happold provided engineering services.
HHRM joint venture (JV) has been awarded a contract to manage the construction of the stadium. The JV comprises Holder Construction Co., Hunt Construction Group, H.J. Russell & Co. and C.D. Moody Construction Co.

The halo display of the stadium was designed by Daktronics. Heery is responsible for providing construction owner representative services. Reeves Young provided multiple heavy civil services for the project.
Sustainable features of Mercedes-Benz stadium
The developers aim to achieve a LEED platinum rating for the project. The stadium will feature a number of sustainable features, including high-efficiency water fixtures that reduce sanitary water consumption by 40%.
LED lighting will reduce the stadium's energy and maintenance costs. In addition, light fittings will be used as way-finding devices and colour-changing LEDs will be used to illuminate the stadium's façade.
