HOCHTIEF Infrastructure wins EUR 140 million Koralmbahn contract in Austria

Joint venture to build Granitz Valley tunnels / HOCHTIEF has 50 percent share in joint venture

(PresseBox) (Essen, ) Together with Implenia Österreich, HOCHTIEF Infrastructure Austria has signed a 01/26/2015 contract to build the Granitz Valley tunnel chain. The client is ÖBB-Infrastruktur AG. The tunnel project mainly comprises constructing an around six-kilometer section of the future Koralmbahn railway. The contract is worth some EUR 140 million, 50 percent of which goes to HOCHTIEF Infrastructure Austria. Work is due to be completed in about five years' time at the beginning of 2020. Final completion of the Koralmbahn railway is planned for 2023.

Apart from the precisest possible analysis of the geological conditions and construction handling details, the bid planning also focused on construction logistics and safety. Overall the contract for the shell construction of the tunnel chain entails cut-and-cover building at the portals and in the Granitz Valley, as well as landscaping and accompanying hydraulic engineering at the Granitz Valley enclosure.

As part of the Koralmbahn railway, the Granitz valley tunnel chain runs between Lavant Valley and Jaun Valley and comprises the Deutsch Grutschen Tunnel (2.6 km), the 600-meter-long Granitz Valley enclosure, and the Langer Berg Tunnel (2.9 km). Like the Koralm Tunnel it will be built as a double-tube tunnel system. The cut-and-cover method will be used to build the rail track in the Granitz Valley area.
