With the attendance of Maria Lorenzatto, godmother of the tunnel, along with the various authorities and companies involved, a groundbreaking ceremony was held for Lot H52 Hochstegen on 4 May 2022. The excavation process for Lot H52 Hochstegen of the East main tube in the south direction has now officially commenced with a blast in the eastern main tunnel.<\/p>\n
As a part of the former lot H51 Pfons-Brenner, Lot H52 Hochstegen, in the territory of the municipality of Steinach am Brenner in the Wipptal valley in Tyrol was subject to a re-planning. More quickly and efficiently advancement of the works will be able by redistribution of the works, with a separate tender and the commencement of work on Lot H52 Hochstegen at the BBT project.<\/p>\n
Locating in a fault zone characterized by a particularly complex geological context: over a stretch of around 500 m, aquifer layers of carbonate rock predominate, Lot H52 Hochstegen was granted to the company Swietelsky Tunnelbau GmbH & Co KG. The boring of this section in a southerly direction, through the so-called Hochstegen zone, must therefore be carried out after stabilization and sealing injections.<\/p>\n
The excavation process of 151 km of the 230 km long BBT tunnel system has been completed now, which covers nearly two-thirds of the entire length, while at present, works are being executed in 5 adjacent construction lots. On 19\/05\/2022 a breakthrough is expected between the Eisack riverbed and Mules sites.<\/p>\n
