Pöyry awarded engineering services assignment for expansion of Lausanne railway station, Switzerland

Swiss Federal Railways (SBB) has appointed Pöyry, as part of the engineering consortium 4G, for the “Galette – Bâtiment Voyageur” (passenger building) main lot at Lausanne station. Pöyry is deploying expertise from across departments including civil engineering, railway engineering and buildings divisions to help implement the large scale project.

To cater for increasing passenger numbers on the route between Lausanne and Geneva, the railway stations in Lausanne, Geneva and Renens will be completely renovated. In Lausanne, the new expanded station will be completed in 2025.

The main lot of this large scale project covers the entire current railway station. The central components are the widening and extension of the platform, expansion of the underpasses and shopping floor below them, the tunnel beneath the historic station building and reconstruction of the building at the southern end of the station. Pöyry will play a crucial role as part of the engineering consortium 4G in the construction project, its tendering and execution. The planning work starts in September 2016, execution is from 2018 and commissioning is envisaged for 2025.

“Pöyry’s experience in the project planning and implementation of the Löwenstrasse station in Zurich, in which we played a leading role, will benefit this project. We are pleased to bring in our cross-disciplinary expertise and contribute to the success of this complex major inner-city project,” says Martin Bachmann, manager of Pöyry’s Buildings Division in Switzerland.

The Galette – Bâtiment Voyageur lot is a particularly demanding mandate, involving the carrying out of a highly complex construction project during normal operations. The planned shifting of the historic protected hall roof, which must be retained and lifted, will be particularly challenging for the engineers. Building Information Modelling (BIM) will be used as part of the project. Thanks to BIM – still a relatively new procedure in Switzerland – the coordination effort between the owners and the companies involved can be significantly reduced.

The value of the order is not disclosed. The order has been recognised within the Regional Operations Business Group order stock in Q3/2016.
