Midfield Terminal at Abu Dhabi International Airport is set to open in 2019. Construction began on this project, designed by Kohn Pederson Fox Associates (KPF), over 6 years ago. When complete, the Midfield Terminal will be one of the largest buildings in the world, at 700,000m². At its largest point, the terminal’s roof span will be almost twice the size of Heathrow’s Terminal 5.
The standout architectural feature of the Midfield Terminal is its curved roof, which has been designed to flow effortlessly into 18 steel arches. When complete, the curvature of the roof will produce a wave-like ripple effect, which in-turn will give the impression that the roof is floating, rather than standing on its arches.
The terminal’s roof–covering 300,000m² in total–is a massive undertaking. The building was designed by Kohn Pedersen Fox Associates, and is representative of the surrounding desert landscape. The roof design employs complex curved geometry including tight convex and concave radii. These require careful design and skilled installation to maintain the architectural intent. This roof system can only be achieved using Kingzip Infiniti. Kingzip Infiniti is a site manufactured complex roofing system that has been tailored to meet the visual, weatherability, structural, fire and acoustic requirements of the client. It is Kingspan's largest area single roofing contract, to date.
In 2016, Abu Dhabi airport handled 24.5 million passengers. In 2019, when the Midfield Terminal opens, the airport will have an updated capacity of 45 million. This gargantuan increase in capacity will have an irrevocable impact upon the city of Abu Dhabi, where architectural innovation is already beginning to take off.
