Stuttgart 21
Chalice-shaped pillars for the new Stuttgart underground station
Most of the production processes required for building the unique shell roof in the Stuttgart 21 project were developed from scratch, thus extending building feasibility limits for extremely complex infrastructure projects combined with the highest architectural requirements on reinforced-concrete construction. The formwork is machined to maximum precision at Züblin Timber using CNC robots. The tool paths are derived directly from the model by means of a parametric interface. The reinforcement of each single chalice-shaped pillar comprises approx. 11,000 different rebar shapes, many of them...
