Replacement of Raiffeisenbank, Gebenstorf

The project

Raiffeisenbank Wasserschloss held an architectural competition for a new replacement building for its Gebenstorf site. From several architectural proposals, Merlo Architekten AG emerged as the winner with their design of a light-flooded concept. The architectural requirements placed high demands on the supporting structure, which is only conceivable with a skeleton construction. In order to achieve a fast and shortened construction time, the architectural concept was realized as a TS3 supporting structure in skeleton construction and a column grid of 6.5m x 5.3m.

The construction method

Skeleton construction is one of the most suitable construction methods for such projects. However, this construction method relies on beams in timber construction. To be able to build without beams, Vögeli Ingenieure opted for the TS3 system. A concrete access zone consisting of a staircase, elevator shaft and technical rooms helps to reinforce the building. In the interior, there are no load-bearing walls at all. A total of 882m2 of cross-laminated timber panels were used, which are rigidly connected to each other using 240 linear meters of TS3 joints.

The challenges

Noise and traffic obstructions had to be prevented as far as possible, which was ensured by the short construction time of the TS3 load-bearing structure. The interlocking of the construction of the load-bearing structure and the setting of the outer walls were planned by Vögeli Holzbau and are part of the fabrication and assembly work, in the sense of a just-in-time process.
