Demand for flights and the range of destinations to which people want to fly has been increasing constantly and is predicted to continue to grow considerably in the coming years.
Airports in Europe, particularly the larger hubs, already suffer from great capacity constraints which lead to late arrivals and less security and safety. Due to its central location and connection point between the European and the Asian continent- Istanbul (Turkey) is the ideal location for a new mega hub in Europe.
The proposed new airport will be located 40km from Istanbul city and is well linked to the existing road and transport network with its own cargo port for goods.
A completely new flexible master plan for the site was developed, with two runways each 4000m long for the new Airbus A380, a cargo airport, a tower and a main terminal strategically located to anticipate and enable future expansion with two satellite terminals to accommodate up to 50 Mio. passenger per year.
The satellites can be reached by automated people mover (transit system) or via walking through an underground shopping mall which connects the satellites to the main terminal.
The main terminal itself is split into two parts: Level 1 accommodates the departure level with check-in, security check, duty free zone and the gates. The ground floor houses the arrival with customs, baggage hall, arrival hall and administration.
For airports a wide spanning structure is important to allow maximized column-free areas for the big internal infrastructure. Therefore a shell construction was developed and found in hyperbolic parabolic shells (HP) which can span 42m. Although the form is anticlastic double curved one shell can be built out of only straight lines. The entire roof of the main terminal consists of 102 HP shells out of steel. As they are all equal in size each shell can be assembled as a modular system on the ground and then lifted up and positioned with a crane.
To solve the daylight issue in this large footprint the canopies are cut back at their highest point where structurally they are not needed. These emerged gaps, opening up towards the sky are cladded with glass and allow natural daylight as well as natural ventilation to come through and create an exciting incidence of light and shadow.
