SNCF Réseau has awarded VINCI Construction – through its subsidiaries VINCI Construction France (lead company), VINCI Construction Grands Projets, Dodin Campenon Bernard, Soletanche Bachy France and Botte Fondations, in a joint venture with Spie Batignolles TPCI and Spie Fondations – the contract to build the new La Défense station and the adjacent tunnels.
The works entrusted to the joint venture are amounting to EUR 496m. They are part of the extension of RER line E towards the west of Paris (Eole). The works will start in the summer of 2016 and will continue for 61 months.
The operation covers building the new La Défense station under the CNIT dome, a highly technical project that entails building an underground cathedral while supporting the existing structures and ensuring operational continuity of the site. The company will also be building one kilometre of tunnels, a 40m-deep and 15m-diameter shaft and a large number of underground pedestrian corridors enabling connections between the RER E and A lines, the L and U lines of the Transilien and the T2 Tramway.
