The EOLE project, an extension of RER E to the west, includes a new station at La Défense. This underground station is built under the existing CNIT ERP. The station's interchange hall is located on level J, the tenth level below the Parvis de la Défense, 30 meters below the level of the Parvis.
The walls and ceilings of the connecting corridors of the emergency accesses and exits to the outside will be clad with a covering called "forme blanche". It is made from a solid-surface composite material. This process of curved shapes, invisibly fastened by inserts, is part of an innovative ATEx-certified system. VIRY is responsible for designing and installing "solid surface" ceiling cladding panels.
Also, following on from our SOADEF3 contract, SNCF Réseau has renewed its confidence in us by entrusting us with the wall cladding work on the 10th and 11th and final level under the station. In the CNIT station, with its underground architecture (30 m below the Parvis de la Défense), the project involved cladding the station's side walls in polished stainless steel sheet, using shaped, draped panels to create an undulating mirror effect.
Challenges to meet
The highly complex geometry of the Avonite panels. Using Tekla Live Link via Grasshopper was the key to the project's success.
From prototype to finished model, the 3D model was used to communicate both internally and externally. Exports were used for BIM synthesis. The Trimble Connect model was at the heart of the project. Daily exports were made to share with our various departments in a fragmented or global way. Trimble Connect was also used as a "3D assembly plan" for the installation of all structures.
