BG in charge of two segments of the project for the metro lines m2 and m3 in Lausanne

17.02.2020

The General Department for Mobility and Roads of the Vaud Canton has entrusted to our engineering office the segments 3 and 4 of operation 2 for the m2-m3 metro development project in Lausanne. BG is the lead of the Davel Consortium, in which also take part the engineering offices Emch&Berger (Lausanne branch) and Stucky, as well as the architecture office CCHE.

Our tasks regard the civil engineering and architectural services for the Beaulieau, Casernes, Plaines-du-Loup and Blécherette stations of the new m3 metro line, as well as the three tunnels that connect them (from tender project to commissioning). This flagship project is part of the Strong Axis (Axes Forts) project for the development of public transports in Lausanne, which is composed of 5 operations and managed by the Vaud Canton, the Lausanne City and the tl (Lausanne's public transport operator).

Already with a long experience on this project

The BG Group is already involved in the same project with the studies of electromechanical equipment, automation and rolling stock (within the Consortium SyMeo and EQUI, in association with Egis).

We have also been asked in 2018 to do an expert review in the plan approval process of operation 1 for the construction of a new tunnel of the m2 line between Grancy and Lausanne Flon stations and for the construction of a new m2 Lausanne-Gare station.

Moreover, BG performed since 2009 studies on earlier phases of this project. The objective was to evaluate a metro solution in comparison to a surface tram and then design a tender project, which was delivered in 2011.

From phased improvements to project review

The preliminary project was then improved in the next phase, between 2012 and 2014, also by BG within the Consortium Paragraph. The project was further optimized by BG, this time unaccompanied, in 2016 (Grancy-Flon tunnel) and in 2018 (Flon-Casernes tunnel). Finally, we did the design review of the final design of operation 1 (the first stage of the m3 line between Grancy and Flon) in 2019.

BG is very proud for having this new assignment, which extends from 2020 to 2027, until commissioning.
