CNIT station, La Défense, France

The construction of the new La Défense station west of Paris will ultimately reduce commuting time and improve daily life for hundreds of thousands of Paris-area residents. The complex structure is located under the iconic CNIT dome.

The highly technical project covers construction of the new La Défense station under the CNIT dome, and consists in building the equivalent of an underground cathedral while supporting the existing structures and ensuring operational continuity of the site. The CNIT offices, shops and hotel must continue to function normally throughout the duration of the works.

Apart from underpinning the CNIT itself, the project calls for building one kilometre of tunnels, a 40-metre, 15-metre diameter shaft and a large number of underground pedestrian corridors to enable passengers to connect between the RER E and RER A lines, the Transilien L and U lines and T2 Tramway line.

The €496 million works contract awarded to the VINCI Construction joint venture via its subsidiaries VINCI Construction France (lead company), VINCI Construction Grands Projets, Dodin Campenon Bernard, Soletanche Bachy France and Botte Fondations, together with Spie Batignolles TPCI and Spie Fondations, is part of the RER Line E extension west of Paris (Eole). Work got under way in the summer of 2016 and will take 61 months to complete. The project will call for 700 people at peak activity and account for four million hours of work, including 300,000 hours earmarked for work integration jobs.

This project confirms VINCI Construction’s major project management capabilities and its underground works and foundation construction expertise.
