Geotechnics and Tunneling: ILF’s part in the Woodsmith Project


ILF is proud to be part of the Woodsmith Project – as a design consultant, working for Strabag’s UK branch to deliver the project for their client Anglo American.

The project in the Woodsmith Mine (ENG) comprises a 37-km-long Material Transport System (MTS) tunnel with a diameter of 4.7 m as well as associated caverns and venti­lation shafts. Mined polyhalite will be trans­ported through this tunnel, in an environ­mentally friendly manner, via conveyor belts under­neath the North York Moors National Park, directly to the materials handling facility in Wilton for further processing. The polyhalite obtained will be used as fertilizer.

ILF has been providing detailed design services for the “Ladycross” steel lining shaft and the associated secant pile shaft in the same location.
In addition, ILF has carried out a CAT III check of the “Lockwood Beck” steel lining shaft design, parts of the MTS tunnel as well as the primary and secondary lining of the sprayed concrete lining tunnels.

ILF to deliver services for the longest offshore gas pipeline in


NNPC (Nigerian National Petroleum Corpo­ration), Nigeria and ONHYM (Office National Des Hydro­car­bures et Des Mines), Morrocco, are progressing with the plans for their mega-project Nigeria–Morocco Gas Pipeline (NMGP). The NMGP, an onshore and offshore gas pipeline crossing the land and waters of 16 countries along the Atlantic coast, shall bring Nigerian gas to North Africa and further to Spain for the European market. The pipeline will not only supply the local markets with reliable energy, it will also support indus­trial and economic develo­pment, create a compe­titive regional power market and benefit all West African countries and their economies.

ILF and DORIS Engineering are delighted to carry out the Project Management Consul­tancy services for the FEED Phase II of this project. ILF and DORIS can make use of their combined expertise and provide funda­mental support to the clients in the delivery of this strate­gi­cally important project.

The PMC services cover the Onshore and Offshore Pipeline and Compressor Station Engineering, the Engineering Surveys, the Environ­mental & Social Impact Assessment (ESIA) and Land Acqui­sition Studies (LAS) and the Project Imple­men­tation Framework. The project explores the potential for using renewable energy resources to power the pipeline and reduce the project’s carbon footprint.

“With ILF having already been part of the Feasi­bility Phase and FEED Phase I of this world-scale project, the award of Phase II to us demons­trates the confi­dence that our long-term clients ONHYM and NNPC have in our Project Management Excel­lence and Relia­bility in delivering world class projects,” said Carles Giro, Area Manager Indus­trial Plants of ILF.

When completed, the over 6,000 km long gas pipeline will be the longest offshore pipeline in the world and the second longest pipeline ever. It has a planned diameter of 48″ offshore and 56″ onshore, with a planned throughput of 30BCMa.
The project coinci­deswith the “Decade of Gas Master Plan” that Nigeria’s President Muhammadu Buhari launched in 2020. On the Moroccan side, this landmark project is part of the South–South coope­ration upheld by King Mohammed VI.

On behalf of the Swiss Federal Roads Office, FEDRO, ILF took the lead in the local site super­vision in an engineering consortium for completing the works at the Belchen rehabi­li­tation tunnel.

The project includes the connection of 11 cross passages to the existing central tube, two service tunnels between the existing and new portal control stations, two crossing passages for the emergency services at the tunnel entrance, a smoke partition wall and an access ramp to the isolated construction site.
The excavation works with a 13.97 diameter TBM taking place at the same time as the struc­tural construction works for the 3.2 km long tunnel were very complex with regard to logistics, design, planning and construction.



Update for one of the most spectacular airports


The Airports Authority of India (AAI) has appointed ILF to carry out a feasi­bility study for the develo­pment and upgradation of Agatti Airport.

This airport is the gateway to the Lakshadweep islands and is the only airport off the West Coast of India. The runway is to undergo a change in design and is to be extended to enable Airbus A320 operation. The terminal building, the apron, the runway end safety area (RESA) system and the taxiway are also to be upgraded for passenger flights. The upgradation of this airport is a challenge due to its special location, the required recla­mation of land and the non-availa­bility of local construction materials and labor.

Along with the feasi­bility study, ILF is also performing the surveying works and environ­mental studies for this project in which environment protection – e.g. marine and wildlife activities such as coral reef rehabi­li­tation – will play a key role.

Gas: Reduction of emissions at compressor stations


Gas Connect Austria GmbH contracted ILF to carry out a feasi­bility study for the reduction of emissions at one of their compressor stations.

In the consi­dered station, three gas compressor units, each with a mecha­nical shaft power of approx. 11 MW, are installed. Each compressor unit is driven by a gas turbine. For the feasi­bility study, two approaches were inves­ti­gated and compared from both an economic and technical point of view. Furthermore, the time required for the imple­men­tation of each approach as well as the potential of each approach for reducing emissions were evaluated.

The scope of the recon­struction work and the amount of investment required for each of the two approaches differs.

One approach would entail repla­cement of one of the gas turbine driven compressor units with a larger electri­cally driven gas compressor unit, capable of covering the entire basic supply of the station. The remaining two gas compressor units would conse­quently only be used when needed, enabling CO2 emissions to be reduced by 95% and methane emissions to be reduced by 88%.

The other approach would not entail any major recon­struction works, but would still reduce emissions from the existing plant. Great potential for savings was disco­vered related to process vent gas. On the basis of these findings, ILF elabo­rated a solution for the reduction of emissions. When the gas compressor units are switched off, the natural gas remaining in the compressor lines is blown out into the atmos­phere; therefore by re-compressing and re-feeding this process vent gas into the gas grid, methane emissions could be reduced by 80%.

2nd Gotthard Road Tunnel – ILF awarded design services contract


As part of IG Nuovo Gottardo, ILF has won a contract for further design works for the 2nd Gotthard road tunnel, the construction of which is scheduled to be completed in 2032. ASTRA, the Federal Roads Office, has extended the existing design services contract until the 2nd tube of the Gotthard road tunnel is opened to traffic.

The new main tube will be excavated using one TBM starting at each portal. The tunnel will be constructed using two shield machines as well as segmental lining. The excavation diameter will be 12.26 m. The northern section of the 2nd Gotthard road tunnel will have an excavated length of a little less than 8 km, and the southern section will have a length of a little more than 8 km. The inner lining of the main tube will be installed in the rear section simul­ta­ne­ously to the excavation works taking place in the front section. While the TBMs will excavate the last few kilometers towards the breakthrough, the struc­tural works for the tube will be completed in the area of the portals. In the course of the design works, the experience gained during projects such as the Belchen Rehabi­li­tation Tunnel could be used to the advantage of the client.

The scope of work rendered by ILF, as part of the IG, comprises the design services for two large under­ground control centers and a total of 67 cross-connec­tions, some with sub-stations and some with expanded tunnel roof sections accom­mo­dating stations for longi­tu­dinal ventilation.

Within the IG, ILF takes on the role of partial project manager for under­ground struc­tures as well as for the TBM northern section and the mined cross connec­tions and for the main works for the under­ground control centers. In addition, ILF is currently in the process of completing the design works for the northern external facilities – the realiz­ation of which is scheduled for mid 2022.

In 2017, ILF was commis­sioned by ÖBB Infra­struktur AG as part of the consortium “Northern Railway Line Team” (Austria) to prepare planning documents for the environ­mental impact assessment (EIA) submission.
Works related to the Southern section of the line were commis­sioned in autumn 2021. With the contract, an option for further tendering and detailed planning was also awarded.

The project “Upgrade of the Northern Railway Line on the Wien Süßenbrunn–Bernhardsthal Section” comprises the section from Wien Süßen­brunn (at km 11.900) to the state border next to Bernhardsthal (at km 77.993). The Northern Railway Line, which shall be upgraded over a length of around 66 km, connects 17 stations is being Austria’s oldest railway line (opened in 1838). The upgrade of the line will increase the speed at which trains can travel, from 120 or 140 km/h to 160 or 200 km/h, and will enable the struc­tural facilities to meet state-of-the-art standards.

From a railway engineering and permit appli­cation point of view, the line has been divided into two sections (the Northern and the Southern section).
Permission for the Southern section was received in autumn 2021; and permission for the Northern section is expected to be applied for in spring 2022.

The entirety of the line (both the Northern and the Southern section) forms part of the “European Railway Traffic Management System (ERTMS) Corridor E: Dresden–Prague–Vienna/Budapest–Constanţa” as well as the priority projects “PP 22: Athens–Sofia–Budapest–Vienna–Prague–Dresden/Nuremberg” and “PP 23: Gdansk–Warsaw–Brno/Bratislava–Vienna”. Furthermore, the line is part of the Rail Freight Corridors 5 and 7 and the TEN‑T Core Network.


Water: ILF as PMC for „The Green Riyadh Project” (KSA)


The Royal Commission for Riyadh City in Saudi Arabia (RCRC) selected ILF as the Project Management Consultant (PMC) for the 1,700,000 m3/day TSE trans­mission network.
This network will provide irrigation water for one of the most ambitious urban greening projects in the world. Green Riyadh is one of Riyadh’s four mega projects launched by the Custodian of the Two Holy Mosques, HM King Salman bin Abdul-Aziz Al-Saud, at the beginning of 2019.

7.5 million trees will be planted in all city features, facilities, and provinces, multi­plying green spaces per capita share. All these plants will be irrigated by a network using only recycled waste­water, which is currently wasted. 83 native tree species that can survive Riyadh’s environment were selected for this project. The greening initiative will improve air quality and reduce tempe­ra­tures (up to 8–15 °C in the shade) in one of the hottest capital cities on the planet. Conse­quently, the initiative will encourage Riyadh’s citizens to follow a healthy lifestyle and ultimately transform Riyadh into one of the world’s leading cities, following the strategic goals of the Kingdom’s Vision 2030.

The objective is to support the Green Riyadh initiative by estab­li­shing a complex and strategic recycled water network with a daily capacity of 1,700,000 m3 (approx. 400 Olympic pools). ILF will perform design review, procu­rement super­vision, construction super­vision and overall project management for three different lots in order to bring treated water from the city’s major waste water treatment plants to its final destinations.

By supporting the Green Riyadh initiative, ILF will not only contribute to the Kingdom’s long-term vision, but our teams will also work at the core of ILF’s very own mission statement, “improving quality of life.”

Hydropower: ILF partner in Hydro4U


Hydro4U is an EU project funded under the Horizon 2020 research and innovation program. In this project, ILF and 12 other partners from eight countries are working together under the coordi­nation of the Technical University of Munich to develop solutions which boost sustainable small-scale hydro­power in Central Asia. Two pioneering hydro­power types shall be imple­mented in demons­tration plants in Kazakhstan and Uzbekistan.

To this day, small-scale hydro­power remains largely unharnessed in Central Asia. Yet there is great potential to transfer European small-scale hydro­power schemes to Central Asian regions. So far there are only few European reference projects in this region as they tend to be consi­derably more expensive than those of Asian competitors.

The Hydro4U project will now adjust two innovative techno­logies developed in Europe to the requi­re­ments in Central Asia. The aim of this project is keeping the costs as low as possible through concept simpli­fi­cation, modula­riz­ation and standar­di­z­ation without compro­mising efficiency. At the same time, the project also focuses on key aspects such as sustaina­bility, environ­mental compa­ti­bility and social acceptance.
In the course of the Hydro4U project two eco-friendly demo hydro­power plants will be installed and assessed: one low-head plant with a capacity of up to 500 kW in Kazakhstan and one medium-head plant with a capacity of approx. 2 MW in Uzbekistan.

Project duration: 06/2021–05/2026

Countries involved: Austria, Belgium, Germany, Kyrgyzstan, Spain, Sri Lanka, Switz­erland, Uzbekistan
