Metro

SYSTRA is present at all phases on the Grand Paris Express, Europe’s biggest infrastructure project. Numerous areas of expertise of the Group are mobilised for this site set to transform the transport offer in the Greater Paris region.

The Grand Paris Express consists of four new automatic metro lines built in the Greater Paris region. With almost 200km of new lines and 68 stations, this new network aims to double the capacity of the Paris metro and link the city’s suburbs.

With 90% of inhabitants living less than 2km from a station, this unprecedented and modern transport offer will be accessible to the greatest number of people and will transport more than 2 million passengers per day.

SYSTRA is mobilised on a very large scope of responsibilities to accompany the Société du Grand Paris (SGP), the government agency responsible for the Grand Paris Expressn, at all phases of the project : since 2011 on design phases, till the completion of the network expected in 2030. There are 250 SYSTRA colleagues working daily to make this project a reality, 25% of whom are women. What is referred to as the ‘worksite of the century’ is also the first transport infrastructure project of this size for which the stations are entirely modelled using the BIM (Building information modelling) method, allowing the use of 3D models and including on the same platform all the design information and next, the operation and structures maintenance information.

The teams have been working together with SGP at their offices in Saint-Denis, as well as at the base sites with local public works companies. The tunnel boring machine (TBM) Steffie-Orbival, launched in 2018 from the Champigny base site on section 2 of Line 15 South, is the first machine to have completed its course out of a total of 21 TBMs to simultaneously dig the 170km of tunnels necessary for the projet.

The creation of the Greater Paris metropolis also mobilise SYSTRA on other assignments with various clients such as RATP, the state-owned public transport operator in Paris, and ADP Group (Aéroports de Paris). In civil engineering as in systems, SYSTRA is leading:
