Barcelona Metro Line 5: Horta-Vall d'Hebron

The project's features include the construction of the subway station caverns using lateral galleries, pile-driving operations used on a non-circular section, the construction of the station accesses using the traditional method of ramps in sections of up to 70 m, and a number of shafts of up to 60 m deep and 16 m in diameter in an urban area.

In addition, the interior installations and architecture were carried out simultaneously in three stations, along with their corresponding access points.
