The winning of European Orders such as the Brenner Base Tunnel and the Turin-Lyons High-speed Railway link has allowed Vicenzetto to consolidate its experience in probes, such as depth boring (up to 1200 m) using wire-line and double and triple-wall core barrels. The strong intervention to integrate the project design of the Tunnel Variation and the Bologna-Florence HS line has further expanded knowledge of consolidated techniques for the core boring of soft rocks such as scaly clays, marbles and argillites.
