Tunnels & Caverns


Tunnel Design &
Tunnel Engineering

Rapid urban develo­pment and the need to protect the environment make it necessary to build more traffic routes and indus­trial plants underground.

For the success of a project, it is critical to choose a techni­cally safe construction method that is still econo­mi­cally viable. ILF has the technical know-how and long-standing project experience to provide clients with profes­sional advice on appro­priate construction methods.

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