Brenner Base Tunnel company, BBT SE, awarded a EUR 966 million contract for the largest construction lot for the Brenner Base Tunnel in Austria, the Pfons-Brenner section.
The consortium is formed by Porr Bau, G. Hinteregger & Söhne Baugesellschaft (Porr subsidiary), Società Italiana per Condotte d’Acqua and Itinera.
The award came after several bidders had presented appeals to the Austrian administrative court, which were however rejected and the consortium headed by Porr was confirmed as awardee.
The stretch includes the construction of 37 km of main tubes between Pfons and the Brenner pass, about nine km of exploratory tunnel and the emergency stop in St. Jodok. The two main tubes will be built using tunnel boring machines. The other stretches will be built by blasting. Construction is expected to last six years.
