PORR and Rhomberg Bahntechnik secure follow-up contract for Koralm Tunnel

Vienna, 20.07.2021 – The consortium of PORR and Rhomberg Bahntechnik has won the tender for the Koralm Tunnel follow-up contract “GU2-TA”. PORR is in charge of the commercial management, with Rhomberg Bahntechnik as the technical lead. The infrastructure project is set to open by the end of 2025. The contract is worth around EUR 110m.

“We will now be able to play a decisive role through to the ultimate project completion of what is our largest stand-alone construction site, a site at which we have been heavily involved since the shell works – that is a great achievement and underlines our wide-ranging expertise in railway construction”, said PORR CEO, Karl-Heinz Strauss.

Following the construction and commissioning of the Slab Track Austria system, the consortium is now responsible for all additional construction measures until the full opening of the 33 km stretch of the major ÖBB rail project between Carinthia and Styria. The scope of the project includes all cabling, telecommunications, energy, security and safety technology, machinery, and other related construction services like tunnelling and metal engineering.

Bundled railway expertise for a crucial infrastructure project

As with the first contract, both partners will rely on bundling their specialist expertise and experience in order to deliver the complex project on time and on budget: “Already with the first lot we took on tasks like supplying the catenary bases as well as manufacturing and operating the temporary systems and structures. We will now benefit from this when installing the rail technology and fittings”, said Robert Kumpusch, Managing Director of Rhomberg Bahntechnik GmbH. “This meant that when we were preparing the offer for the corresponding lot, it was easy to achieve synergies with other tasks and naturally also to secure economic benefits”.

Once completed, the Koralm railway will cut travel time between Graz and Klagenfurt from almost three hours to just 45 minutes. As many as 256 high-speed trains will use the line each day, reaching speeds of up to 250 km/h.
