Circular Economy: ILF provides EPCM services


ILF is respon­sible for providing EPCM services for Synthos’ project to expand the production capacity for InVento products. The EPCM services which ILF is providing include the design, bidding and procu­rement processes and construction management for the project. ILF’s tasks also include the creation of a 3D model of the project for all phases and disciplines.

Rafał Blankiewicz, Managing Director of ILF Consulting Engineers Polska, on EPCM projects: “Our company has experience in managing invest­ments in the EPCM model. We success­fully completed our first project using this formula in Poland between 2007 and 2010, at a time when the model was still quite unknown.”

ILF has completed the building permit design for the construction of the second production line at Synthos and has obtained the building permit. In the near future, ILF will recommend the contractors for the individual purchase packages and will begin the process of taking over the construction site. The new production line is scheduled to be completed in the first half of 2023.

InVento is an ecolo­gical product used in thermal insulation, manufac­tured using an ecolo­gical geopo­lymer additive which acts as a factor reducing the heat transfer coeffi­cient and thus improving the thermal insulation properties of final building products. InVento products are charac­te­rized by full recyc­la­bility and contain 30% recycled content coming from post-consumer waste in their formula.

Design works for Northern Feeder Line of Brenner Base Tunnel


Together with one of ÖBB Infra­struktur AG’s and DB Netz AG’s partners, ILF has been commis­sioned with a new project as part of the four-track upgrade of the Northern Feeder Line of the Brenner Base Tunnel. This project comprises the route design and project planning works needed for the submission of the environ­mental impact statement (in Austria) and the conceptual design (in Germany) for the Kirnstein–Schaftenau cross-border section. The approx. 13 km long cross-border Laiming Tunnel is the core element of this upgraded section.

In addition to the Laiming Tunnel, the respective adjacent open-track sections and the associated traffic facilities are also being designed. All of the design services will be carried out using the BIM method and the scope of these design services can also be extended to include the detailed design phase (in Austria) and the basic design phase (in Germany).

Having already been involved in the previous design phases for this section, in parti­cular in the route selection procedure, ILF is pleased to be able to continue working on this complex project in the further design phases.

The section being upgraded forms part of the Northern Feeder Line of the Brenner Base Tunnel, which will be the longest railway tunnel in the world when it is completed. Thus it consti­tutes an indis­pensable part of the Scandinavian–Mediterranean Corridor (Scan–Med Corridor) from Stockholm to Naples – the most important North–South railway link in Europe.
