PORR consortium has recently signed an order for the construction of Austria’s largest tunnel project. The confirmation of the order for the construction project was signed on Friday, August 10th 2018, by the representatives of the PORR consortium, consisting of PORR, Hinteregger (the subsidiary PORR acquired last year), as well as joint venture partners from Italy and the CEO of the European Brenner Basetunnel project company.
“We are exceptionally proud to have received the tender for Austria’s largest tunnel project to date. The 18km-long ‘Pfons-Brenner’ lot presents a genuine challenge in view of the complex geology and the restricted space available”, said PORR CEO Karl-Heinz Strauss. The CEO further added, “You can only be charged with a construction project in the region of EUR 1 bn if you have the right skills and expertise – perfectly in line with the PORR philosophy”.
According to a recent media release by PORR, the construction phase for lot H51 involves building two main tunnel tubes between Pfons and Brenner, around nine kilometres of exploratory shafts, and the emergency zone at St. Jodok. The two main, single-track tunnel tubes will primarily be driven with tunnel boring machines (TBMs) with an excavation diameter of 10.37 m – this means that a stretch of up to 30 metres can be driven per day and per TBM. The excavation of the exploratory tunnel will be excavated by drill & blast method and secured with shotcrete. The entire lot will be supplied via a single access tunnel.
The construction team includes PORR Bau GmbH, G. Hinteregger & Söhne Baugesellschaft m.b.H., Società Italiana per Condotte d’Acqua S.p.A., Itinera S.p.A.
PORR’s tunnelling experience includes driving more than 600 km of tunnels and the Group has already built an exploratory and access tunnel for the Brenner Basetunnel.
