Swietelsky Tunnelbau GmbH & Co KG from Salzburg have secured the EUR 102.18 million contract, excluding VAT, for the construction work of the Hochstegen Lot H52, on the Austrian side of the BBT project. A total of approximately 2.6 km of main tunnels towards Brenner will be excavated as well as 0.6 km of interconnecting tunnels, five cross-passages and 1.2 km of exploratory tunnel southwards. Work to complete the crossover point (2.5 km) at the southern Wolf hub is also planned. However, the main focus of the construction lot is the excavation of the exploratory tunnel southwards through the so-called Hochstegen formation. This is carried out in the area under the protection of waterproofing injections and stabilisation taking place during the excavation progress.
