In an effort to broaden its experience, FERPI in 2000 began a new activity within the sector of civil engineering and mining, particularly focused on interior works, with the execution of access tunnels for mines and also tunnels for highways and high-speed trains.

In the mining sector, FERPI has abundant experience in the construction of sloping tunnels with a 60 square meters section and over 3,000 meters length. In the field of public works, drilling of road tunnels can reach a 110 square meters section with lengths of up to 1,000 meters.
