Andreasturm Zurich
Images 1–3: Atelier Roman Keller, Zurich
The new 80 m high Andreasturm was built directly next to the tracks at the eastern end of Oerlikon station. The twenty-two-story high-rise is used for offices, supplemented by a restaurant and meeting rooms on the ground floor and the first floor.

The structure is designed as a classic skeleton construction in reinforced concrete. Vertical loads are transferred from the in-situ concrete flat slabs via precast columns and the two centrally located cores, which also ensure the horizontal stabilization of the building. Cast-in-place bored piles handle the load transfer into the subsoil.
Prestressed beam-and-slab floors span the large column-free spaces on the first floor and enable the 10 m cantilever over the ground floor.
The building’s proximity to the heavily used railway tracks requires elastic decoupling of the structure.
