Two large adjacent exhibition halls connected under an 81m span roof. The total construction area of the exhibition centre whole project is approx 445,000 m2

Judge's comment:

This enormous development comprises four huge buildings, each of which contains two large clear span exhibition halls 162m long and 81m wide.

The impressive roof structure of each hall is supported by 81m span steel cable catenaries in an elegant and logical arrangement which is repeated many times over to achieve the extraordinary scale of this project.

The apparent simplicity of the appearance hides a great deal of complexity in the structural behaviour. The judges noted the degree of care taken by the designers to deal with this complexity without compromising the architectural clarity of the scheme, and still achieve noteworthy economic and sustainability targets.
