New Nuremberg-Ingolstadt Railway Line

ILF's engineering services encompassed the project management of the entire route (approx. 74 km). ILF was also in charge of the design services (from detailed design to construction design) and construction supervision for the central section (approx. 18.4 km).

The Nuremberg-Ingolstadt high-speed line, with a design speed of 300 km/h and a maximum longitudinal gradient of 20‰, was constructed between 1998 and 2009 as a twin-track line for mixed traffic (ICE passenger and freight trains) with a slab track system.

ILF's design services started in 1991 with the production of the preliminary design and the detailed and permit application design for the central section. This section has three mined tunnels (total length some 15.6 km, as well as excavation cross sections exceeding 120 m²), with trafficable rescue adits and shafts (total length more than 10 km), regional and overtaking station at Kinding, as well as 9 bridges including any necessary road relocation.

ILF provided the basic design and technical tender documents for the design and build contracts as well as the construction design for the excavation of all mined tunnels, adits and shafts of the route (approx. 31 % tunnels).
Furthermore, ILF prepared the permit application design for modifications of previously approved design as well as the permit application design for fire and disaster control.

In a joint venture headed by ILF, construction supervision was carried out for the central section in the course of the construction works. In addition to the geotechnical documentation, karst control measures were planned and supervised.

The project management (in a joint venture) of the entire route included technical and crisis management, document control and quality management, as well as contract management for the entire route.
