| The installation of a double helix stair with a height of 9,50m in the front court of the KPMG branch office in Munich (architects: Steidle & Partner) belongs to one of the technically most elaborated works of Olafur Eliasson. The shape of the stair derived from the spherical surface of a bowl. The spiral stair was designed to stand on the ground on only point without support or stilts. The axle tube was made out of several cutted and bented steel segements with a diameter of 32,4cm and a wall thickness up to 6,5cm (!). These segments were welded together in the workshop. Experts warned against the danger of vibrations and oscillations that could arise from several people going up and down the stairs. Thus, we had to look for a possibility how to reduce these vibrations. After long months of planning and testing and due to the team work of many experts and professionals we finally achieved our goal by installing an unique and invisible damping system into the bented tube. After that, the wooden stairs and the handrails made out of stainless steel were installed on the tube. | |
