ILF designs tunnel and open-track section for railway line

more

As part of the new railway line between Köstendorf and Salzburg, an efficient connection will be built as an addition to the 150-year-old existing line. The 21.3 km long railway line is being planned by ILF within the framework of two joint ventures (open-track section and tunnel), with the 16.5 km long Flachgau tunnel comprising the key element.

The open-track section before and after the tunnel has a total length of 4.3 km and crosses the Fischach tubular bridge which has a span of approx. 42 m.
The planned Flachgau tunnel will have two single-track tunnel tubes. The design services will be carried out using the BIM method and shall, in addition to the early service phases, also include the option for the tender and construction design together with the geotech­nical engineering on site as well as the maintenance planning. This tunnel, which will be constructed and advanced under­neath the existing line using the New Austrian tunneling method (NATM), a tunnel boring machine (TBM), the cut-and-cover method and box jacking, is a very challenging assignment with complex planning and design works.

ILF looks forward to developing this demanding project.

Expansion of wastewater treatment plant Frankfurt/Main (GER)

more

The Stadt­ent­wäs­serung Frankfurt am Main (SEF, https://www.stadtentwaesserung-frankfurt.de/) entrusted ILF Consulting Engineers together with a German partner to plan, execute and implement the expansion of the Niederrad Waste­water Treatment Plant (WWTP).

The Niederrad WWTP is currently reaching its maximum design capacity of 1.35 million PE. The expansion is therefore urgently required in order to be prepared for future develo­p­ments in the constantly growing Frankfurt area. For this reason, the number of secondary aeration tanks (with a volumetric capacity of 7,200 m³ each) will be increased from 8 to 10, and the number of secondary sedimen­tation tanks (with a volumetric capacity of 1,875 m³ each) will be increased from 32 to 40. The project comprises the smooth integration of these new tanks, as well as the associated mecha­nical, electrical and SCADA equipment, into the existing plant while maintaining conti­nuous plant operation and compliance with effluent requirements.

Additio­nally part of the assignment are the re-routing of existing pipework and the construction of an access road.

ILF will be involved in all eight service phases of this project, which are in accordance with the German Official Scale of Fees for Services by Archi­tects and Engineers (HOAI), including the building permission appli­cation as well as construction super­vision and commis­sioning. The completion is scheduled for February 2027.

ILF and GEV sign MOU for hydrogen project

more

ILF Consulting Engineers and Global Energy Ventures (GEV) have signed a Memorandum of Under­standing (MOU) to identify and develop green hydrogen projects in Europe and Australia that include a compressed hydrogen (C‑H2) generation and trans­por­tation solution, offering a valuable addition of marine trans­por­tation to the H2 value chain.

ILF will design the upstream infra­st­ructure from the producer to the export or loading facility and the downstream infra­st­ructure from the import or unloading facility to the consumer, while GEV will cover the port-to-port trans­por­tation of hydrogen using compressed gaseous hydrogen ships. For projects that involve importing hydrogen from regional markets in close proximity to Europe, such as the Middle East and North Africa region, GEV has identified an oppor­tunity to leverage offshore loading capacity and develop a compressed gaseous hydrogen solution for the offshore wind industry. Thus, a fleet of vessels could provide an offshore loading and transport solution for areas where an subsea cable or pipeline on seabed is not suitable.

Jens Kottsieper, ILF Business Develo­pment Manager, commented, „The trans­por­tation of large volumes of gas is an issue that ILF has been involved with for over 50 years. We are pleased to be able to complement our pipeline expertise with GEV’s expertise in the cost-effective transport of hydrogen by ship. Working with GEV will allow us to provide our customers with even more compre­hensive advice on their trans­por­tation issues in order to develop a solution that meets their specific needs.”

„Scaling up Green Hydrogen in Europe”

more

Date and time:
February 26, 2021
11:00 AM — 12:00 PM (CET) / 10:00 AM — 11:00 AM (GMT)

Green hydrogen is incre­a­singly seen as an indis­pensable part of the Energy Transition. Ambitious targets for producing it have been set for the mid-2020s and 2030.

Many projects and use cases are proposed, but how is an industry that currently only operates at the level of tens of MW going to reach GW-scale quickly – and effici­ently – enough? Will access to cheap energy at the boundaries of and/or outside Europe help to make green hydrogen compe­titive in the mid to long term, even taking the need to transport hydrogen into account?

ILF, Dentons  and Operis have produced a white paper on Scaling up Green Hydrogen in Europe. In it, we look across the hydrogen value chain and consider both the physical and contractual/regulatory infra­st­ructure that will be needed to make the vision of a hydrogen economy a reality. We consider how to match supply and demand for hydrogen; suggest possible models for financing hydrogen projects and trading their output; and review the role of public financial support and other policy inter­ven­tions. We are optimistic about the prospects, but also realistic about some of the challenges facing this new industry.

We will be launching the white paper at the online seminar.

After a brief presen­tation of our conclu­sions, a panel of industry experts who are engaged in commercial hydrogen projects will debate the issues and share insights from their own experience.

Speakers from ILF, Dentons and Operis will be joined by:

  • Julia Prescot, Chief Strategy Officer and Co-Founder at Meridiam Infra­st­ructure, Member of the UK National Infra­st­ructure Commission
  • Roland Schulze, Managerial Adviser on Low Carbon Techno­logies, European Investment Bank
  • Marinus Tabak, Plant Manager, RWE

Please click the „Register now” button below if you would like to attend the cost-free online seminar, or to receive a copy of the white paper when it is released.

We look forward to meeting you virtually and to an interesting discussion. Please do not hesitate to contact ILF if you have any questions.

ILF still active at Vestfoldbanen railway tunnel project

more

As part of the ongoing Vestfold­banen railway upgrade scheme, state-owned Norwegian railway infra­st­ructure company Bane NOR is building 10 km of new double-track railway between Drammen and Kobbervikdalen.
In 2018, ILF Consulting Engineers was hired by the Norwegian contractor Veidekke Entre­prenør AS as the designer of the most techni­cally challenging section of the project, a 290 m‑long tunnel mined in difficult geology below the ground­water table. The excavation commences in low cohesion glacio­fluvial deposits and progres­sively transi­tions into full face rock excavation. Extensive ground impro­vement works in the form of jet-grouting will be executed from the surface in advance of the tunnelling works.

Norway has a long tradition of rock tunnelling, however large span soil tunnels are not common in the country. ILF is able to bring expertise and success on similar tunnel designs to this project.

Initially, ILF prepared the Tender Design and supported Veidekke during the Compe­titive Dialogue compe­tition. After the EPC Contract was awarded to Veidekke in October 2019, ILF developed the Concept Design to later carry on with the Detailed Design, which is currently underway and includes a BIM model which is then integrated into a combined model of all the works within the contract.

Operation & safety eqpt.for Germany’s longest bi-direction tunnel

more

The 3.6 km long Kramer Tunnel will be the longest two-way tunnel in Germany. It is primarily meant to relieve through traffic in downtown Garmisch-Parten­kirchen and towards Grainau/Eibsee and the federal border at Griesen. In 2020, the Staat­liche Bauamt Weilheim contracted ILF Consulting Engineers to carry out the following design phases: 5 to 9 (among others, prepa­ration of tender documents, contract awarding and site super­vision) for the instal­lation of the operation and safety equipment.

The Kramer tunnel will predo­mi­nantly be constructed as a mined tunnel. Furthermore, the tunnel will have two opera­tions buildings outside and a cavern inside the tunnel with a 26 m high exhaust air chimney. The tunnel is planned with cross passages acces­sible to pedestrians and vehicles as escape routes. More than 1,300 LED lights will ensure that necessary lighting is provided in the Kramer Tunnel. 16 jet fans (55 kW each), and 2 exhaust air fans (420 kW each) ensure that the required venti­lation concept is implemented.

Since 2017 ILF has been success­fully involved in the Kramer tunnel project, carrying out tunnelling and road design services, prepa­ration of tender documents and risk analysis as well as the first three design phases for the operation and safety equipment.

A revolution in reporting

more

On account of the growing complexity of day-to-day project work, the demands on reporting are incre­asing signi­fi­cantly. Due to the lack of automated processes, classic reporting is prone to errors, only partially up to date and time consuming as well.

By imple­menting analy­tical software solutions such as MS Power BI, the great potential of infor­mation management can also be used for reporting. The aim is to visualize project-specific data both quanti­ta­tively and quali­ta­tively, and in a struc­tured and descriptive manner. These project cockpits are used for quality assurance and also for project coordi­nation and control.
For the project, 2. S‑Bahn-Stamm­strecke München (2nd Munich S‑Bahn Main Line), the Client, Deutsche Bahn, requested quality assurance for BIM in the design phase for various disci­plines. In the course of the general BIM coordi­nation, ILF Consulting Engineers developed the quality assurance process by means of MS Power BI. In a multi-stage procedure, the quality of the individual technical models was evaluated and presented in a report. After the client’s approval, a uniform workflow, an inter­di­sci­plinary template and a project-specific user guide were developed.

For the project, this consti­tutes a new standard of quality assurance, which has been imple­mented for the first time with such profes­sio­nalism and which will be a yardstick for future projects.

Grafing–Großkarolinenfeld section of Northern Feeder Line to BBT

more

The Northern Feeder Line forms part of the Trans-European Scandi­navian-Mediter­ranean Corridor, which stretches from the South of Finland to the island of Malta. The current project is located along the Munich–Verona axis and is a component of the Northern Feeder Line to the Brenner Base Tunnel.

DB Netz AG has recently commis­sioned ILF Consulting Engineers, as part of a joint venture, to provide design services for the route selection process involving public parti­ci­pation for the planned Grafing–Großkarolinenfeld project area. The Grafing–Großkarolinenfeld section will consist of a new twin-track high-speed line running from Grafing station to an area south of Tunten­hausen. As part of this joint venture, ILF has also been involved in the Großkarolinenfeld–Schaftenau section in Austria since 2016. This section is located next to the Grafing–Großkarolinenfeld section.

The electrified twin-track high-speed line shall provide greater capacities for rail traffic and contribute to relieving traffic on the existing Munich–Innsbruck railway line. Facili­tating train speeds of up to 230 km/h, the new line is furthermore advan­ta­geous for passengers traveling long distances. The Grafing–Großkarolinenfeld section has a length of approx. 23 km and a maximum longi­tu­dinal gradient of 12.5 ‰. The entire processing of the project has been done using BIM, starting from the early design stages.

Core elements of the design contract include develo­pment of feasible route alter­na­tives, environ­mental inves­ti­ga­tions and inter­di­sci­plinary route selection, as well as perfor­mance of a compre­hensive baseline survey and a project area analysis. The design works will be accom­panied by extensive citizen participation.

TuRisMo reduces the risk in road tunnels

more

With the imple­men­tation of EU Directive 2004/54/EC, tunnel safety became a central aspect in the design and operation of road tunnels. By doing so, Austria intro­duced a perfor­mance-based approach to tunnel safety. The Austrian tunnel risk analysis model (TuRisMo) is defined in the Austrian guideline RVS 09.03.11, which describes one of the first methods for analyzing and assessing road tunnel safety in a quanti­tative manner.

TuRisMo combines different metho­dical elements for analyzing a tunnel system in its entirety and follows a holistic approach. The use of TuRisMo offers the possi­bility of quanti­ta­tively recording and assessing almost all decisive factors influ­encing tunnel safety. This contri­butes to ensuring that invest­ments for tunnel safety are used as cost effici­ently as possible.

Combining infrastructures: H2 pipelines in cable routes

more

For the large-scale distri­bution of hydrogen in Germany, the Fachverband der Netzbe­treiber (FNB) – the German Association of Network Operators – proposes to make modifi­ca­tions to the existing natural gas network as well as to a number of new construction projects.

A compa­rison of FNB’s proposed hydrogen network with under­ground cable projects in Germany shows that the routes for the direct current trans­mission lines, which are already in the planning stage, could be meaning­fully used to complete the planned H2 pipeline network. In addition, this could increase the H2 transport capacities in a North–South direction to appro­xi­mately 10 GWh/h.

In an initial study conducted by ILF Consulting Engineers, it became apparent that pipe laying is techni­cally feasible within a large part of the route for the power trans­mission lines, with only a few sections leading to increased planning and construction costs. For the smallest part of the routes, a small-scale re-routing of the H2 pipeline is likely to be advisable for economic reasons. The next steps shall be the exami­nation of the general condi­tions, especially with regard to the project’s chances of receiving authority approval and a detailed consi­de­ration of the technical feasibility.
