A competition was held to find an economical solution for the roofing of the existing artificial ice rink and cycling track that could be realized within a short construction period (7 months including foundation work).
The delicate supporting structure, consisting of four main columns and eight cable-braced air columns, is spanned only by a thin membrane made of translucent polyester fabric, which is anchored to the foundations at the edge via masts with cables. The membrane is part of the load-bearing primary structure and not just a space-enclosing shell. The different degrees of translucency of the radial membrane reinforcements at the high points present the force curve in an appealing way.
