EXPRESSION OF INTENT: Three undulating steel waves - the structural frame of a new museum - have taken shape on a hillside just outside Berne, Switzerland. Local contractor Zwahlen Mayr has topped out the $5M steelwork for what is to be a centre celebrating the work of painter Paul Klee. It has been designed by engineer Arup and Italian architect Renzo Piano. Each of the three vaults comprises a series of inclined arches. These are fabricated from 1.5m deep box section beams which are designed to take bending as well as compression forces.
The museum 'grows' out of the hill, with arches rising from the ground at the back of the building to reach a height of 65m at the front.
