PROJECT SUMMARY
Designed and undertaken by the developer Société du Grand Paris, the Grand Paris Express project commenced in 2010. It is expected to entail some twenty years of works, mostly underground. This new transport system, which will include up to 200 km of automatic lines, will encompass 68 new stations and as many districts: as part of the construction of the Grand Paris Express, four metro lines will be extended (4, 11, 12 and 14) and four new lines created (15, 16, 17 and 18).
Key challenges:
- guaranteeing the robustness and durability of the structure
- ensuring the safety of users in the stations and metro trains
- guaranteeing reliable risk management of potential damage to existing buildings during a major underground infrastructure project of this magnitude.
