Brenner Basistunnel (BBT SE) has launched a EUR 855 million Europe-wide tender for the construction of Pfons – Brenner stretch (lot H53). The tender will be closed on 16th May 2022.
The contract will be awarded using the MEAT (most economically advantageous tender) criterion and in addition to the price, quality-base criteria are involved in the bid evaluation, too.
The tendered contract comprises the excavation of the two main tunnel tubes northwards up to the border to the H41 construction lot and southwards up to the state border at the Brenner Pass. The exploratory tunnel is being excavated up to the state border.
A total of 25.2 km of main tunnels are to be excavated, of which approximately 15.2 km using a TBM and 10 km by blasting. In addition to this, 1.3 km of exploratory tunnel are to be excavated. The cross-connecting passages, with a total length of 2.3 km, will also be excavated. Besides this, several works regarding the inner lining will be carried out.
If the tender procedure proceeds according to plan, the contract of the Pfons-Brenner construction lot will be awarded within 2022. The construction period of the tendered works is estimated at 69 months (almost six years).
The newly tendered construction lot is situated between the townships of Pfons to the north and Gries am Brenner to the south. With Pfons – Brenner stretch (H53) and Hochstegen (H52), two new and different construction lots have been designed. Both stretches were part of the former construction lot Pfons – Brenner (H51).
Besides the Sill Gorge construction lot (H41), the Pfons – Brenner (H53) is still one of the biggest stretches in the Austrian project area.
As of January 2022, on the Brenner Base Tunnel project 4 main construction lots are under construction which include the Mules 2-3 and Isarco River Underpass, in Italian project area, while Sill Gorge, Sill Gorge – Pfons on the Austrian territory.
In total, the Brenner Base Tunnel system will include about 230 km of tunnels. Currently, 149 km have already been excavated of which 53 km main tunnels, 55 km are exploratory tunnels and 41 km are other types of tunnel works such as access tunnels or logistic tunnels.
