The project is conceived to have International scale and presence when approached from landside and airside. The flat roof form makes the landside and airside elevations of equal importance and avoids contemporary cliches for airport roofs.
The terminal is orientated by the need for the apron to serve both the existing and future runways and for arriving and departing aircraft from both runways to have easy access to both domestic and International airbridges. Thus the linear pier is perpendicular to the existing runway system and the main terminal building enjoys an axial relationship with approach road from Ankara.
The simple building form is given interest by the visibilty of the interior elements through totally transparent sides and the introduction of daylight through a perforated roof system. The glazed elevations of the building have a reverse incline which both increases visibility into the building by reducing reflections and improves the solar shading afforded by the projecting roof. The area of wall glazing permitted by thermal regulations is maximised by using low emmissivity double glazed units. A proportion of the glazed units are provided with integral sun protection which reduce solar gains to a level which can be managed by mechanical systems.
The steel roof structure is conceived of as a large table supported on steel pilons at 36m centers and propped by vertical wind trusses at 6m centers around the perimeter of the building. The 300cm x 150cm frameless glazed units are hung form trusses by cantilevered cast stainless steel arms. All floors are concrete and supported on a 12m x 12m grid which is totally independent of the steel pilons which pass through it. The large pilons in the center of the building are 3m x 3m in plan and well as bracing the building against lateral wind loads are the vertical distribution for the mechanical and electrical services. All primary plant and equipment is located in the basement to be both discrete and have efficient distribution routes.
A particular feature of the proposal was the walk through check in arrangement where each desk has its own baggage belt so that passengers walk between desk through to departures without having to turn back through other people queueing to check in. This arrangement maximises passenger flow rates.
