The extension of line 11 will connect the current Mairie des Lilas terminus to the RER station E Rosny-Bois-Perrier.
It will facilitate travel in eastern Paris, particularly in this sector of the Seine-Saint-Denis, and will serve many facilities along the route.
Six new stations serve the 5 cities covered by the extension: Les Lilas, Romainville, Noisy-le-Sec, Montreuil, Rosny-sous- Bois. The project also provides for the creation of a future maintenance workshop in Rosny-sous-Bois as well as a new centralized control point for the line at Bagnolet.
The technical complexities, especially at the interfaces between linear infrastructures, led to RATP’s choosing to adopt the BIM process for this project. The company inherits the design model to develop their execution studies and to restore the DOE model as well as the GMAO model, organized according to the RATP criteria.
