Metropolitan Railway Line of 47.8 km, connecting different areas of Barcelona with El Prat Airport. Four TBMs have been required for the excavation of the whole line. The tunnel is divided in two sections, one upper and one lower. Train will operate in both sections, after its final implementation.

CIVILSUB teams have participated in the construction of almost 7 km of the intermediate prestressed-concrete slab that separates the upper and lower tracks of the tunnel. We have also executed internal structures of ramps, walls, platforms, and technical rooms, facilities of BT and AT. For its implementation, four corbels formwork carriages have been used, as well as two monorails in order to fit prefabricated slabs and distributing the material. Upper and lower embedded via and civil works in station dwells have also been concreted by us.
