Client, ÖBB-Infrastruktur AG has awarded the Hochtief/Implenia/Thyssen JV the contract to build the Gloggnitz Tunnel in Austria. The total contract volume for the “SBT 1.1 Tunnel Gloggnitz” JV is some €457M.
The future east portal of the 27.3km long Semmering Base Tunnel (SBT) is situated on the edge of the city of Gloggnitz in southern Lower Austria. The SBT 1.1 Tunnel Gloggnitz contract section is around 7.4km in length and will be driven from two sides – both from Gloggnitz and via the intermediate access in Göstritz – using NATM. The JV will build two parallel, single-track tunnel tubes with 16 cross passages at maximum intervals of 500m.
Due to the challenging geology and to ensure optimal logistics, an approximate 1,000m access tunnel will also be driven. Furthermore, two 260m deep shafts – with the caverns required for construction operations – will be created at the end of the tunnel. Completion of the Gloggnitz Tunnel is scheduled for 2024.
The Semmering Base Tunnel is one of the most important infrastructure projects in the heart of Europe. The mega rail tunnel between Gloggnitz and Mürzzuschlag is located on one of Europe’s most important traffic corridors – the Baltic-Adriatic Corridor – which runs from Gdansk (Poland) to Ravenna (Italy) and connects important economic areas and ports between the Baltic and the Adriatic.
Commissioning is planned for 2026.
