The project concerns arranging the exploratory tunnel for geological prospecting, excavated with a Æ 6.20m-TBM (plant displacement and construction of the road platform), and excavating 22 interchange niches, 8 of which intended for plant equipment during the construction of the base tunnel, distributed along 7 km of the tunnel-length.
The intervention also includes building a driveway, to prepare for the work’s execution, and installing the first phase coating along the entire tunnel development.
Commissioned by TELT (Tunnel Euralpin Lyon Turin), the project will be carried out by Webuild in an association of companies.
