Overview

Situated in the alpine destination of Vals, Switzerland, the new building for the 7132 Hotel is set to be the world’s tallest hotel and also the tallest building in western Europe. The luxury hotel features 107 rooms and suites, as well as restaurants, a ballroom, gallery, library, gym, pool and business facilities. With a maximum of four rooms per floor, 7132 Hotel offers guests panoramic views of the Valser Valley and Swiss scenery. The hotel tower’s narrow profile and reflective glass façade helps its tall structure blend within its alpine surroundings.

We are providing structural design services to Morphosis Architects for this unique, high-rise hotel.

Highlights

  • Due to the proposed slender profile of the tower, we collaborated with the project wind tunnel consultant, RWDI, to evaluate the performance of the tower for a variety of height scenarios under wind events anticipated in the mountain valley.
  • The resulting structural system consists of a supercore, extending the height of the tower and enclosing vertical transportation systems and MEP services and back-of-house spaces. The supercore will be constructed with high-strength concrete and high-strength reinforcing steel. Located at the top of the tower, a tuned mass damper device will provide motion control during extreme wind events.
  • The guestrooms facing the valley will have a column-free perimeter, featuring floor-to-ceiling glass windows, accomplished by suspending the floor slabs from the supercore and a centrally located spine wall.
  • Additional challenges with the mountain-valley environment include the top rock and soil layers composed of sediment and moraine layers unsuitable to support the weight of the tower.
  • We collaborated with Langan International to engineer a foundation system including a deep-drilled, pier foundation system through the bedrock beneath the surface soil.
