The ATLNext Central Passenger Terminal Complex transformed the arrivals and departures areas of Hartsfield–Jackson Atlanta International Airport with two large ETFE canopies. The structures shelter eight traffic lanes as well as bus lanes and passenger waiting areas, providing protection from sun and rain while creating a distinctive entrance to the domestic terminal.
Each canopy measures approximately 265 metres in length. Together, they comprise around 32,000 square metres of pressurized, double-layer ETFE cushions mounted on a curved framework made from approximately 3,500 tonnes of steel. The lightweight and translucent material allows natural daylight to reach the areas below while reducing solar heat gain.
PFEIFER Structures was responsible for the fabrication and installation of approximately 345,500 square feet of ETFE cushions. The accurately manufactured cushions were adapted to the long, curved geometry of the two steel structures and securely connected to the supporting framework. The low weight of the ETFE enclosure reduces the loads on the large-span steel structure compared with conventional glazing.
Thousands of computer-controlled LED fixtures illuminate the ETFE cushions from within. The lighting system can display changing colours and patterns, transforming the canopies into a highly visible architectural landmark at night.
The North Canopy was completed in 2018, followed by the South Canopy in 2019. The staged installation allowed airport and roadway operations to continue throughout construction.
