The first section of the new Grand Paris Express metro line will be executed by setec tpi. The south-western section of the new line 15 which, at its completion, will run 360° around Paris, extends from Pont-de-Sèvres to Villejuif. It comprises 12km of new tunnel, 8 new stations and 13 emergency access shafts.
The future automatic metro will run at an average speed of 60 km/h (stops included) with a maximum speed of 100km/h. It will transport 1,000 passengers per train every 90s in rush hours.
- The 12kms are executed entirely underground with TBM up to a depth of 60m with an inner diameter of 8.70m (external diameter of 10m) that incorporates the two tracks.
- In advance of the tunnel boring works, the soil stabilisation using injections of a significant number of underground quarries is required. Specially in the limestones layer right above the tunnel section.
The 8 underground stations are designed to host 108m long trains, with a width of between 25m and 30m depending of the number of users and a depth from 25m to 55m. This depth, quite significant at some points of the alignment, is justified by the need to avoid the aforementioned underground limestone quarries. The excavation of the station is undertaken with the help of 70m deep and 1.80m thick diaphragm walls, executed prior to the start of the earthworks.
The interior design of the stations meets the highest standard specifications in terms of functionality, safety and operational quality in order to provide the highest quality output both to our client and the final users of the projects.

setec tpi leads the Design & Construction Joint Venture. setec tpi provides with all the services ranged in the French MOP law (Maîtrise d’Ouvrage Publique), from the start of the scheme design to the commissioning. In a summary:
- At the design stages: scheme design (AVP), detail design (PRO) and preparation of the ITT/RFP dossier for the construction stage (ACT)
- At the construction stages: VISA (verification of construction execution documents), approved for construction design (DET) and the construction management, steering, coordination and commissioning phases (AOR and OPC)
setec tpi provided the aforementioned services for the civil engineering infrastructures as well as for the building engineering elements and the operational design of the stations and the emergency exit shafts (power, plumbing, smoke extraction, …).
