ILF embarks on new technologies to combat climate change


On November 30, 2017, Jens Kottsieper and Michel Kneller will be presenting a white paper on decentralized hydrogen production from renewable energy for the transport sector at the ÖGEW/DGMK Autumn Conference in Vienna, Austria.

In order to meet the climate objectives of the 2015 Paris Agreement to further reduce CO2 emissions, it will be necessary to increase the renewable energy share in the global energy mix. One potential solution would be to convert surplus renewable energy to hydrogen through a process of electrolysis, store it and make it available to the transport sector. Mr. Kottsieper and Mr. Kneller will also present key findings and lessons learned from the Demo4Grid project that is currently being implemented in Innsbruck, Austria.

You can have a look on the white paper here:

Brenner Railway Axis Extension: ILF continuing on track


The Schaftenau–Radfeld Junction in the Lower Inn Valley (Austria) forms part of the northern feeder line to the Brenner Base Tunnel. The upgrade of this section is part of four-tracking the line in the Lower Inn Valley.

With this project, the Austrian Federal Railways (ÖBB) and the Austrian Ministry for Transport, Innovation and Technology (BMVIT) intend to increase the line capacity and eliminate bottlenecks for the Brenner Base Tunnel to achieve full efficiency. In addition, the project will bring traffic relief for the Lower Inn Valley and reduce travel time, as design speeds of 230 km/h will be possible.

The line will have a total length of approx. 20.5 km including 11.7 km in mined and cut-and cover tunnels and 5.6 km in open-track sections. Furthermore, the project will include the construction of four trough structures with a length of 3.2 km.

ILF Consulting Engineers will be responsible for preparing the design documents for the preliminary authorization of the environmental impact assessment (EIA) pending legal permission for the mined tunnel near Angath. Together with partners, ILF will also be in charge of the cut-and-cover tunnels and trough structures.

ILF at the Hydro 2017 in Seville


ILF Consulting Engineers will be present at the HYDRO 2017 in Seville, Spain, from 9 to 11 October 2017.

Arlberg Tunnel Reopened to Traffic


After a construction period of three years the Arlberg Tunnel on the S16 Arlberg Road (Austria) was officially reopened to traffic.

Having a length of approx. 15.5 km, the longest road tunnel in Austria was equipped with 37 additional escape routes and another eight emergency lay-bys. In total ASFINAG invested EUR 154 million in the safety upgrade of the tunnel, and has applied state-of-the-art technologies (high-pressure water mist system, thermal scanner at both portals, AKUT system, etc.) in the tunnel.

ILF Consulting Engineers was entrusted with the project management and the supervision of the electromechanical installations and control systems.


ILF to provide design services for Nordbahn Wien


In July 2017 ÖBB-Infrastruktur AG commissioned ILF Consulting Engineers, together with partners, to provide permit application and EIA design services for the railway project Nordbahn Wien Süßenbrunn–Bernhardsthal in Austria.

Breakthrough of Stein and Lind Tunnels on the Koralm Railway Line


On 28.07.2017 the top heading breakthrough of the 2.1-km-long Stein Tunnel was celebrated after 12 months of construction. The Stein railway tunnel forms part of the St. Kanzian string of tunnels on the Carinthian side of the new Koralm railway line, which connects the cities of Graz and Klagenfurt (Austria). The breakthrough of the bench is scheduled to take place by the end of August.
The 0.5-km-long Lind Tunnel of the St. Kanzian string of tunnels had already been completed on 21.02.2017 after 8 months of excavation. The waterproof permanent linings, consisting of reinforced concrete, will be installed in the near future. Track construction will not go underway before the structural works for the St. Kanzian string of tunnels will be completed at the end of 2019. The section between Althofen on the Drava River and St. Kanzian is due to go into operation by 2022.

After completing the conceptual design, permit application design, and tender design services, ILF Consulting Engineers have been awarded a contract by the Austrian Federal Railway ÖBB in mid 2015, entrusting them with the construction design and on-site geotechnical monitoring services.
