Eiffage and NGE has been awarded in consortium by Tisséo the contract to carry out the civil engineering works for the tunnels, stations and structures on new Line C of the Toulouse metro between the Laporte ancillary structure and Raynal station (lot 2). The total amount of the contract is worth almost EUR 590 million (Eiffage’s share: 65%; NGE’s share: 35%).The consortium, led by Eiffage through its subsidiary Eiffage Génie Civil, will be responsible for carrying out the studies and construction of a 8.416 kilometers tunnel, six stations, five related intersection structures and a specific tunnel connected to the maintenance area. The contract also encompasses construction of nine safety galleries connecting shafts to the tunnel.Various advanced new techniques will be used for the project, including two next-generation tunnel boring machines and fibre-reinforced concrete segments using less steel in 95% of the project, manufactured on its own by the consortium thanks to a new plant in the Toulouse area. Lastly, the Carasol® soil analysis technique, developed by Eiffage, will be implemented. This technique takes just two hours to analyze excavated materials rather than the 3-5 days with traditional methods, reducing temporary storage and thus trucks rotation.
