Implenia wins another major contract in Austria

Implenia is technical lead in consortium that has won contract for Granitztal tunnel system | Contract worth around CHF 168 million (Implenia's share 50%) | Proof of international tunnelling unit's strength | Another success in Group's infrastructure business development in Europe

Dietlikon, 17 December 2014 – The 130 kilometre-long Koralmbahn line is currently the largest expansion project within the Austrian rail network. When completed in 2023 it will provide the first ever direct link between the major centres of Graz and Klagenfurt. It will form part of the "Adriatic-Baltic" axis – an international corridor stretching from Bologna to Danzig. ÖBB-Infrastruktur AG, the company responsible for the contract, has commissioned a consortium consisting of Implenia and Hochtief Infrastructure to build the 7.8 kilometre section between St. Andrä and Aich. Implenia is the technical lead for the construction of the new line, which is twin-track along its entire length.

The contract is worth around CHF 168 million (around EUR 140 million; Implenia's share: 50%). Most of the section requires tunnelling, and the core element is the 6.3 kilometre Granitztal tunnel system. This involves trenchless subsurface construction of the Deutsch-Grutschen tunnel (approx. 2.5 kilometres) and the Langer Berg tunnel (approx. 2.9 kilometres). The section between these two tunnels (approx. 0.6 kilometres) will use conventional open construction techniques, and will include a bridge over the Granitzbach stream. The work also includes hydraulic engineering, landscaping, road building, pipeline construction and materials installation. Construction is due to begin in the first quarter 2015. Completion is scheduled for April 2020.

Back at the start of 2014 a consortium consisting of Implenia and Austrian company Swietelsky secured a contract worth around EUR 623 million (around CHF 770 million, Implenia's share: 50%) to build part of the 27.3 kilometre "Semmering Base Tunnel" (SBTn). Winning the Granitztal contract emphasizes the strength of Implenia's international tunnelling unit. The contract marks a major success in the group's strategy to expand its infrastructure business in Europe.
