A consortium of Implenia (50%) and Demathieu Bard Construction (50%) has been awarded the contract by the Tisséo Public Transport Association of Greater Toulouse for Lot 3 of the future Line C of the Toulouse Metro. Line C is scheduled to run from Colomiers to Labège from the end of 2028. The project will last 57 months and has a total volume of EUR 331.4 million. Implenia's stake amounts to around EUR 166 million.Lot 3 comprises the excavation of 3,814 meters of tunnels under a densely populated urban area and civil engineering works for the construction of four underground stations at a depth of 24 to 39 meters and three ancillary structures. For tunnelling, the consortium proposed the "Variable Density Conveyor" method, an innovative solution to meet the challenges of the different soil conditions. The planning and implementation of the project is carried out using BIM (Building Information Modeling).In its offer, the consortium paid particular attention to sustainability: By using segments made of fibre-reinforced concrete, the CO2-Footprint of the project is kept as low as possible and the trees on the site are protected and preserved throughout the construction period. In addition, 98% of the excavated material is recycled.
