Tunnels and caverns

Tunnels and caverns

The rapid development of our settlement areas and the protection of our environment make it necessary to build more traffic routes and industrial plants underground. This avoids impacts created by additional buildings and structures above ground.

A decisive factor for the success of a project is choosing a technically safe construction method and ensuring the greatest possible economic efficiency at the same time.

ILF has, for more than three decades, been entrusted with engineering services for outstanding projects. All in all ILF has been involved in the design and implementation of more than 1,000 km of tunnel structures.

Highlights

Fields of expertise:

  • Road and railway tunnels
