A consortium comprising PORR and its subsidiary Hinteregger has secured a contract worth nearly €966m to build an 18km section of the Brenner Base Tunnel in Austria.
The 64km-long Brenner Base Tunnel (BBT) is a railway tunnel that is currently under construction, and will connect Austria and Italy.
As part of the contract, the PORR-Hinteregger consortium will be responsible for building the lot H51 Pfons-Brenner section in collaboration with Italian joint venture partners Società Italiana per Condotte d’Acqua and Itinera.
PORR CEO Karl-Heinz Strauss said: “The scope of the project, the changeable geological conditions and the limited space constraints of the construction site all represent considerable challenges.
“On highly demanding, large-scale projects such as the ‘Green Line’ metro in Doha, we have proven that we are capable of mastering exceptionally complex tasks within the promised time and quality, and on budget.
“This certainly worked in our favour in the award process for the Brenner Base Tunnel.”
The scope of this contract involves construction of two main tunnel tubes between Pfons and Brenner, nearly 9km of exploratory shafts, as well as an emergency stop and transfer point at St. Jodok.
The two main single-track tunnel tubes will be driven with tunnel-boring machines with an excavation diameter of 10.37m. A stretch of up to 30m is expected to be driven per day and per tunnel-boring machine.
Exploratory shaft excavation will be carried out with the drill & blast method and secured with shotcrete. The full lot will be delivered through a single-access shaft.
Construction work is expected to begin this year and be completed by 2024.
