Semiramis V-Zug, Zug

The project

For the Tech Cluster Zug, researchers from the group of ETH architecture professors built together with Müller Illien Landscape Architects, TS3 and other partners. a planted architectural sculpture. The 22.5 meter high structure consists of five geometrically complex wooden shells, which - slightly offset from each other - are supported by eight slender steel columns.

The construction

Always in sync, four suspended robot arms pick up their assigned assigned to them, perform a high-precision dance and finally place the panels in the panels in the room according to the computer design. Once the machines have placed their four panels next to each other and then bonded them together at the ends with the TS3 casting resin without without pressing pressure. In this way, between 51 and 88 of such wooden panels are joined together to form a wooden shell. The TS3 system is mainly used for the construction of floor slabs, but also enables structures such as structures such as Semiramis.

The challenges

The slender and tall structure is lushly planted with large shrubs and trees, giving it a stately and thus has a considerable dead weight. At the same time, it provides a large attack surface for the wind. Thanks to the advantageous round shape of the shells, it is guided around the structure.
