Worksite management on the project to extend FGC lines in Terrassa

Project summary

The project to extend a line of the Ferrocarrils de la Generalitat de Catalunya (FGC) urban rail network involved building three new stations – UPC‑Vallparadís,a RENFE interchange and Can Roca – linked by two 4 km‑long one‑way tunnels.

Project details

This contract covered the second phase of the extension project and essentially consisted of the construction of two tunnels, an interchange station, the interior structure of the northern part of the Can Roca station, the train depot, track laying and the electrification of the line.

Each of the two tunnels was created using a tunnel boring machine excavating 3,100 m. They are circular one-way tunnels with an interior diameter of 6 m, each measuring 3,150 m long.

The contract also included the redevelopment of the area affected by the work: a local park, Parc del Nord, and Avinguda del Parlament.

A working shaft was also created for tunnel operation and to be used as a train depot.

The interchange station contains an 80 m-long platform and an underground passageway connecting to the RENFE Terrassa Estació del Nord station.

The first phase of the project covered the construction of the UPC‑Vallparadís and Can Roca stations, while the second phase of work was the construction of the other stations, as well as the tunnels, interchange station, interior structure in the northern part of the Can Roca station and train depot, plus track laying and the electrification of the line. Each of the tunnels was built using a tunnel boring machine, which dug 3,100 m. Each tunnel has an interior diameter of 6 m. A working shaft was created for tunnel operation and to be used as a train depot. In addition to the RENFE interchange station, diaphragm wall boxes were created for the crossroads of the park south of the UPC station with the area where the tunnels connect with the existing headshunt at the Rambla d’Egara station. Emergency exits in Avinguda de l’Abat Marcet, Torrent Monner, and Rambla d’Egara and shafts for compensation grouting were also all built.
