Press Review Investor Information 28 October 2010 KORALM TUNNEL: STRABAG WINS AUSTRIA’S LARGEST CONSTRUCTION CONTRACT ■ Main section of Koralm railway between Graz and Klagenfurt ■ Contract value € 570 million ■ Construction period between 2011 and 2018 Vienna, 28 October 2010 Today, Thursday, ÖBB Infrastruktur AG and Austrian construction group STRABAG signed the contract for the construction of the Koralm Tunnel. A consortium under STRABAG’s technical and commercial leadership will begin work in early 2011 in order to complete construction on the main section by late 2018. With a value of € 570 million, it is the largest construction contract ever awarded in Austria. “We are currently finishing work on the Gotthard Base Tunnel in Switzerland. It is wonderful that we now have the opportunity to again deploy our decades of expertise in tunnelling in our home country of Austria,” says Hans Peter Haselsteiner, CEO of STRABAG SE. The Koralm Tunnel is the main section of the new Koralm railway link to be built between Graz and Klagenfurt and represents an important section of the Baltic-Adriatic axis of TEN Corridor No. 23 between Gdańsk, Warsaw, Vienna and Bologna. Upon completion, the Koralm Tunnel will be 32.5 km long, making it the longest railway tunnel in Austria and one of the longest in the world. STRABAG, working together with Jäger Bau GmbH, will construct two parallel, single-track bores with a length of 20 km each using two tunnel boring machines with a diameter of 9.9 m. The 8.5 million tonnes of excavated material will be used to produce 1.0 million m³ of concrete for the inner lining of the tunnel. The work represents a particular technical challenge as the only access possibility to the underground construction site is through a 60 m access shaft near Deutschlandsberg in southern Styria. STRABAG company STRABAG AG Construction volume € 570 million STRABAG share 85 % Order backlog Q4 / 2010 Segment Special Divisions & Concessions Construction period Early 2011 – late 2018 Client ÖBB Infrastruktur AG STRABAG SE is one of Europe’s leading construction groups. With some 75,500 employees, STRABAG generated a construction output volume of € 13.0 billion in the 2009 financial year. As a result, STRABAG is listed in the Fortune Global 500 list as one of the largest companies worldwide. From its core markets of Austria and Germany, STRABAG is present via its numerous subsidiaries in all countries of Eastern and South-East Europe, in selected markets in Western Europe and on the Arabian Peninsula. STRABAG’s activities span the entire construction industry (Building Construction and Civil Engineering, Transportation Infrastructures, Special Ground Engineering and Tunnelling) and cover the entire value-added chain in the field of construction.

ÖBB-PORR Slab Track System for the Koralm Railway — World of PORR
World of PORR 168/2016 PORR Updates ÖBB-PORR slab track system for the Koralm railway Success with our own technology The Austrian Federal Railways (ÖBB) continue to rely on the railway construction expertise of PORR Bau GmbH. Under its leadership, 3276m of railway line will be installed using the “ÖBB-PORR elastically supported slab system”. Construction work on the slab tracks of line 1 in the Hengsberg Tunnel and the Weitendorf FW12 underpass, Different types of ÖBB-PORR track support slabs Oberbau 66.03 section has started on 5 February 2016. Line Image: PORR AG 2 was built also under the leadership of PORR Bau GmbH in 2010 as a slab track and has been operational since December 2010. The following concrete and surface works will be carried out for ÖBB: Line 1 slab tracks Track cover with load bearing sound-absorbing slabs Switch in slab tracks Light mass-spring system in the Weitendorf FW12 underpass Load distribution slabs Pre-ballasting on the connecting line The main construction work on the slab tracks will be carried out over a 7 week period from 11 July to 26 August 2016 during which time the tracks will be closed. The work will mainly be carried out on rails in shifts. This construction work is a part of the new Koralm Railway Line project between Graz and Klagenfurt. Construction of the Koralm Railway Line began in 1999. The new 130km-long line will be completed in 2023. The rail journey from Graz to ÖBB-Porr slab tracks with load bearing sound-absorbing slabs Klagenfurt will then only take 45 minutes, with trains reaching Image: PORR AG speeds of up to 230km/h.

Koralm Tunnel
KORALM TUNNEL – DEVELOPMENT OF TUNNEL SYSTEM DESIGN AND SAFETY CONCEPT Christof Neumann, Florian Diernhofer, ILF Consulting Engineers, Austria Gerhard Harer, Josef Koinig, OEBB Infrastruktur Bau AG 1 ABSTRACT The 32.8-km-long Koralm tunnel requires additional measures to guarantee a sufficient safety level. The methodology applied to define safety measures for this very long tunnel is on the one hand based on a set of guidelines and on the other hand based on the specific boundary conditions of this tunnel. These tunnel-specific conditions are considered by establishing customized safety targets. As a result of an investigation into the construction and operating phase, the tunnel system was determined to consist of two single-tube tunnels, an emergency station, no crossover and cross- passages every 500 m. The emergency station in the centre of the tunnel, which incorporates various considerations, was designed to accommodate staggered platforms and a refuge room with a length of 800 m. With a view to the incident management strategy to be adopted, characteristic operating scenarios were analysed to realistically reflect the sequence of events in case of an emergency. 2 THE KORALM TUNNEL PROJECT The Koralm tunnel is one of the key elements of the Koralm high-capacity railway line, which connects the cities of Graz and Klagenfurt in the south of Austria. The Koralm railway line is part of the Baltic-Adriatic Axis, which represents the easternmost crossing of the Alps and links several Eastern European countries Koralm line with Koralm tunnel and Vienna with southern Austria and northern Italy. The Koralm line is a 130- km-long high-capacity railway line engineered for a design speed of 200 km/h.
