In contrast to the neighbouring construction lot, H41 Sillschlucht-Pfons, the segments in construction lot H53 Pfons-Brenner cannot be manufactured directly on site. As such the segments, which in total will exceed 530,000 tonnes in weight, are being delivered by rail to the construction site.
The Max Bögl group of companies, from Sengenthal in Bavaria, was commissioned to produce more than 54,000 segments.
These will be installed by the two tunnel boring machines Wilma and Olga, which will begin driving north in September 2024, to produce the inner shell of the two main tunnels in construction lot H53 Pfons-Brenner. Each of the two TBMs will cover a distance of approximately 7.5 km in a northerly direction.
While the two tunnel boring machines are being assembled, the first segments reach the construction site in the municipality of Steinach am Brenner by train.
“Due to the limited space, we were unable to produce the segments directly on the construction site, as was the case in construction lot H41 Sillschlucht – Pfons. That’s why, together with the Max Bögl group of companies, we found an innovative solution to avoid transport on the road,” confirms Christoph Mellitzer, deputy construction manager of BBT SE for the Pfons-Brenner section.
