As part of the ongoing Vestfoldbanen railway upgrade scheme, the state-owned Norwegian railway infrastructure company Bane NOR is constructing 10 km of new double-track railway between Drammen and Kobbervikdalen.

In 2018, ILF was hired by the Norwegian contractor Veidekke Entreprenør AS as the designer of the most technically challenging section of this project: a 290 m long tunnel mined in difficult geology below the groundwater table – the Soil Tunnel. ILF prepared the tender design, supported Veidekke during the Competitive Dialogue competition, and developed the conceptual design as well as the detailed design of the soil tunnel. This includes a BIM model that is integrated into a combined model of all of the works within the contract.
ILF staff from our offices in Austria and Norway attended the breakthrough ceremony for the Soil tunnel top heading together with more than 200 other guests.

ILF is proud to be part of such a remarkable and prestigious project.
