This crossed-shaped exhibition gallery is 507m x 287m. The arches of the prestressed cable-arch structure span 47.5m and a height of 28.8m.  

Judge's comment:

As a result of ingenious and thoughtful structural engineering, this excellent cruciform exhibition gallery achieves a beautiful clarity and transparency in spite of its enormous scale.

The span of the tall and slender arches is up to 48m. This would normally demand relatively deep arch ribs to ensure stability against buckling. But here, the designers have introduced a tensioned cable system to provide the necessary stability to the steel ribs, enabling them to be only half a metre deep.

Furthermore, the three-dimensional nature of the arrangement reduces horizontal displacements substantially and facilitates bay-by-bay construction.

The judges were delighted with this scheme and impressed by the elegance of the detailing, as well as the clarity of the overall engineering solution.
