On the 14/02/2023 the official inspection of the second TBM for the H41 Sill Gorge-Pfons construction lot of the Brenner Base Tunnel took place at Herrenknecht AG in Schwanau (D). The single-shield TBM (diameter 10.37m, length 160 m, weight 1,440 t) will be named Ida. The name was chosen by the pupils of the St.Peter-Ellbögen primary school, which is also located in the project area of this construction.
The TBM, will be dismantled piece by piece and transported to the west assembly chamber in Ahrental, south of Innsbruck where its "twin sister" Lilia is currently being assembled in the east assembly cavern. In Spring 2023 the machine will be launched southwards for its approximately 8.3 km-long excavation of the west main tunnel. The boundary of this construction lot extends into the municipal area of Navis. For further information in the tunnelbuilder archives on the BBT project please click here, at/16 and it/103.
