After the application procedure, the employment of the PhD candidate could start in June 2018. For details regarding the PhD position, click here.

Koralm Railway Line connects: breakthrough in Untersammelsdorf


One of the most challenging structures of the Koralm Railway Line, the Untersammelsdorf Tunnel near St. Kanzian (Austria), was officially completed with the breakthrough of the top heading in late April.

The Untersammelsdorf Tunnel is the most complex of six tunnel structures and has a total length of 665 m and a maximum overburden of 30 m. Large parts of the tunnel were excavated adopting the cut-and-cover method, while in the portal areas the top-down construction method was used. A tunnel rescue site for emergency services is being built at the tunnel’s western portal.

Together with partners of ÖBB Infrastruktur AG, ILF Consulting Engineers has been working on the design of the tunnel structures in the “Mittlern–Althofen” section since 2006.

Drinking water transport continues to be ensured for Saudi Arabia


In early April 2018 the EPC contractor Mapa Construction and Trade Co. Inc. commissioned ILF Consulting Engineers to carry out the detailed design for the Rabigh-Jeddah/Makkah Water Transmission System in Saudi Arabia. It is one of the largest drinking water transmission systems ever tendered by the client and owner SWCC.

The overall system comprises two independent pipeline systems (Rabigh-Jeddah/Makkah and Rabigh-Mastorah) which are both supplied by the new Rabigh desalination plant. The total throughput amounts to 1.3 million m³/d and is transported from Rabigh to Makkah and Briman respectively via a 200 km long 80” twin line. In total 684 km of pipeline will be laid and 8 pump groups will be installed. 12 reservoir stations will be erected along the pipeline. The total storage capacity of the steel tanks in the different stations is 3177 m³.

ILF’s scope of work includes hydraulics and process, all stations and buildings including housing compounds for the future operating personnel, and the entire pipeline system. Furthermore ILF supports the EPC contractor in the design of the mechanical equipment, the commissioning of the transport system on site and prepares the operating manual for the overall system.



Kick-off for linking up Ghana and Burkina Faso

Groundbreaking ceremony for environmentally friendly electricity


After an intensive design and approval phase the groundbreaking ceremony for the GroAYinzersdorf Wind Farm (Lower Austria) took place in early April this year.

The EUR 17 million project is meant to supply 7,500 households with clean electricity as early as this year. The wind farm consists of three wind turbine facilities with a total of 9.9 MW and is an important step towards renewable energy and climate protection in Austria.

ILF Consulting Engineers was commissioned by WindLandKraft GmbH to carry out the design and project management services for the wind farm including roads and crane hardstand areas as well as cabling to the substation.


Switzerland’s largest pumped storage plant put into operation


After a construction period of approx. 10 years, the new Limmern pumped storage power plant (Switzerland) of “Kraftwerke Linth-Limmern AG” was commissioned with a ceremony at the end of March 2018.

With an output of 1,000 MW, the new power plant is the largest pumped storage power plant in Switzerland and has a height difference of 620 m. The dam, located at 2,470 m above sea level, is the highest dam in Europe.

For Switzerland and the international electricity industry, the power plant is a huge battery that can be used in an environmentally friendly way to stabilize the grid and to ensure peak coverage.

Together with partners, ILF Consulting Engineers had already been entrusted with the design of the underground facilities (powerhouse, transformer cavern, pressure tunnel, surge tank, access tunnel, energy discharge tunnel) in 2009.

ILF has no borders


Engineers Without Borders Austria is a non-profit association which has set itself the task of implementing projects in the field of technical development cooperation. The members and contributors are of different age groups and fields of study/professions. Everyone works on a voluntary basis. Since 2015 there is a regional group in the Tyrol with currently about 40 members, among them architects, civil engineers, physicists, psychologists, linguists and many more. The regional group is currently working on the “EduZapa” project, which aims to rehabilitate a school in rural, poverty-stricken Mexico. The first implementation phase took place in the summer of 2017, with a further phase being planned for 2018. This project is financed exclusively by donations.

ILF supported the association with a donation at the end of 2017 and now intends to work more closely together. In particular, ILF plans to contribute to the technical project and design by making in-house expertise available to the project team.

ILF continues to ensure clean drinking water in Saudi Arabia


Already in 2014 the National Water Company (NWC) commissioned ILF Consulting Engineers to provide design services for the “South Dhahran Residential Project” of the Saudi Aramco national oil company. Scope of services for this new “Residential Housing Complex” is to ensure the necessary water supply as well as wastewater treatment and disposal for the future 70,000 residents.

The project encompasses a seawater desalination plant (100,000 m³/day), a 20 km long drinking water supply pipeline and a 17 km long wastewater collector pipeline to the new wastewater treatment plant (70,000 m3/day). The project furthermore envisages reusing the treated sewage effluent (TSE) for irrigation purposes via a 17 km long pumping main. A new 10 km long transmission pipeline DN 1,200 for wastewater between an existing and the new wastewater treatment plant is included in the project.

After the feasibility study ILF also carried out the EPC tender of the mentioned system components, provided support during contract negotiations and compiled contract documents. Currently the project is in the implementation stage where ILF carries out design review and site supervision.

How the climate changes ILF


All over the world changes in the climate are observed resulting in conditions that are too hot, too wet, causing a rise in sea levels, and an increase in the number of extreme events, such as storms, floods, droughts or landslides. Given the ever increasing importance of the topic, ILF has now published a White Paper titled “Climate Change challenges and solutions in infrastructure planning and adaptation”, which gives an overview of the topic and outlines solutions to cope with the challenges involved.

Tunnelling works for northern tube of Koralmtunnel KAT2 completed


Together with partners, ILF Consulting Engineers has been involved in the site supervision of the Koralm tunnel KAT2 contract section on behalf of the Austrian Federal Railways (ÖBB) since 2010. After the start of the construction works in 2011 and the start of the TBM drive in 2013 the completion of the excavation works was celebrated on 18 Feb 2018. This means that over a period of 59 months of tunnelling some 17,145 m of tunnel were excavated for this contract section.

Forming part of the Baltic-Adriatic Axis, the Koralm tunnel shall, after its completion, contribute to significantly reducing travel times in passenger traffic and to improving the conditions for environmentally friendly railway freight traffic. The 32.9 km long single track railway tunnel was divided into three contract sections, with the 19 km KAT2 section being the longest one.

ILF is both in charge of the site supervision and of the technical management of the joint venture for the site supervision.

Light at the end of the tunnel – breakthrough of Eppenberg Tunnel


After an advance period of approximately one year, the Eppenberg Tunnel was broken through on February 2, 2018.

The Eppenberg Tunnel is part of the Swiss Federal Railway Line between Aarau and Olten which is being widened to four tracks. The tunnel was advanced with a mixed shield tunnel boring machine over a length of 2.6 km and will have a total length of 3.2 km long upon completion of the construction works. The Eppenberg Tunnel is scheduled to be put into operation by the end of 2020. It will provide a significant increase in capacity of the main artery from Zurich to Bern.

Together with partners, ILF Consulting Engineers was awarded a contract for the project works (basic design to construction design) and the site supervision works as part of an overall planning mandate for the 4-tracking of the Aarau–Olten railway line. In addition, the mandate comprises the railway technology works after completion of the civil works.
