Kuwait International Airport (Terminal 2)

Kuwait International Airport is currently being consistently expanded to make the emirate a new air hub in the Gulf region. For the terminal building (T2) designed by Foster + Partners, Werner Sobek was commissioned with the structural engineering of the main supporting structure, the facade engineering and Building Information Modelling, BIM.

BIM for Complex Mega-Projects

The new terminal has an edge length of almost 1.2 km and a clear height of up to 25 m. Its supporting structure consists of the main structure made of reinforced concrete, a shell structure made of steel and reinforced concrete, the steel trusses, a secondary roof structure and the facade. The main reinforced concrete structure is characterised by elements borrowed from bridge construction – main hollow columns whose dimensions and loads are comparable to bridge piers and building cores.

320,000 m² roof area without expansion joints

The roof area of the terminal measures 320,000 m². In addition to its size, the new building is characterised above all by the complexity of the roof structure: It spans up to 145 m and cantilevers up to 50 m, providing a naturally shaded entrance area and a spacious and flexible interior. Despite its large scale, the roof had to be designed without expansion joints, which had extensive implications for the dimensioning and calculation of all components.

A roof structure is a statically highly indeterminate system. The interaction between the different components is therefore very complex; every change in the stiffness of one element has a significant influence on the static load of other components. Therefore, the challenging design of could only be realised with the help of complex digital methods and tools.
