Conversion of Lausanne railway station: Coordination of 30 digital models

Project overview

As part of the project Léman 2030, SBB (Swiss Federal Railways) is upgrading the capacity of Lausanne station. To do this, the railway tracks are being rebuilt, and the platforms are being extended to a length of 420 metres. New underpasses will be built to make it easier for passengers to access the platforms. At the same time, the station square will be completely redeveloped and a large underground connection will be created between rail, metro and bus. Both projects will be realised within an extremely complex framework of existing transport carriers and infrastructure systems, preferably without interruption to ongoing operations. Basler & Hofmann is responsible for overall BIM coordination between all 20 involved project partners, with around 30 models divided up by subsection, contractor and construction phase. Particularly when it comes to the complex planning of the construction phases, an approach based on BIM really proves its worth.
