(ANSA) - TURIN, NOV 26 - The construction site opens in France where, from mid-2022, 23 kilometers of the double-tube maxi-tunnel of the new Turin-Lyon railway will be excavated, which will measure 57.5 in total. This morning, the group of companies that awarded the work (the agent Vinci Construction GrandProjects, Dodin Campenon Bernard, Vinci Constructions France TPLyon, WeBuild) set up shop in La Praz, in the municipality of Saint André in Maurienne. Preliminary acts include the formal commitment of companies to comply with the Mission 5 protocol "which strengthens and systematises the supervision of safety at work" in infrastructure construction sites.
In the excavation site, three milling machines will be used and the traditional method will be used in the geologically more complex sections.
The safety site of Praz will also be built, the communication branches every 333 meters between the tunnels, the technical rooms, the niches and the galleries for exercise and safety.
In total, approximately 65 months of work are planned for an amount of € 1.43 billion and a commitment of over 1,000 workers.
6 French municipalities are concerned.
In the next few days, the construction site for the section of the tunnel between the French entrance portal at Saint-Julien-Montdenis and Saint-Martin-la-Porte will also be started, headed by the grouping led by Implenia Suisse.
