The €590m (US$633.9m) Lot 2 contract for Line C, between the Laporte ancillary structure and Raynal station, comprises construction of an 8.4km tunnel, six stations, five intersection structures and a tunnel connected to the maintenance area. The contract, awarded by Tisséo, the public transport authority for greater Toulouse, also includes construction of nine safety galleries connecting shafts to the tunnel.
Eiffage has a 65% share in the consortium and NGE 35%.
The companies say innovative techniques will be used for the project, including two “next-generation” TBMs and, in 95% of the project, fibre-reinforced concrete segments using less steel. The consortium will also use Effiage’s Carasol soil analysis technique, which takes just two hours to analyse excavated materials rather than the 3–5 days with traditional methods, reducing temporary storage and thus rotation of lorries.
As part of its environmental commitments, the consortium aims to recover nearly 90% of the excavated material. It has also given undertakings to reduce the project’s carbon footprint through the use of primarily renewable energy, clean vehicles, eco-designed installations.
The project will start this spring. Handover of the infrastructure is scheduled for late 2025 and the new line will be commissioned in 2028.
As reported yesterday by Tunnels & Tunnelling, the contract for Lot 3 of Toulouse Metro’s Line C was won by an Implenia/Demathieu Bard Construction joint venture. Lot 3 includes building 3.8km of tunnel, as well as four underground stations at a depth of 24-39m, and three ancillary structures.
