Project Description

This impressive multifunctional centre is located to the west of the Swiss capital, Bern, and has 60 shops and boutiques, a multiplex cinema, 10 restaurants, a pool, spa and fitness areas, a hotel, a conference centre and a senior citizen home, etc.

Project Requirements

This complex extends across a motorway, so an existing highway tunnel had to be extended as part of the project. The technical, time and economic requirements were high.
A lot of different parts of the complex needed different system solutions, e.g. basement, parking areas, storage and logistics areas, sanitary and pool areas, the steel structure, façade elements, the roof and so on.
