Brenner Basis Tunnel Construction Lot (Mules 2-3)
3TI is responsible for the Health and Safety Management during construction of the Brenner Basis Tunnel (lot “Mules 2-3”). This lot is the final part of the BBT, on Italian territory stretching from Mules town to the Italian border (Bolzano area). The BBT consists of two-tubes each equipped with a single track, linked every 333 m by connecting side tunnels. The BBT is characterized by the “exploratory tunnel” running from one end to the other between the two main tunnels and situated about 12 m below them. The excavation of the two main tunnels (40,3 km), and the exploratory tunnel (14,7 km), will be carried out using traditional methods (drill and blast) and mechanical methods (TBM).
