The main “Access to la Sagrera” works contract has been complemented by the track installation contract, which covers the full scope of works required to bring the high-speed tracks through La Sagrera into service, as well as the contract for the architectural works and systems in the train technical servicing area (Phases A and B).
Valladolid Railway Network. East Section. Civil and track work. Spain. This project comprises a total of 17.5 kilometres, with two branches at the initial section and two temporary connections to the existing line at both ends. A Iberian-gauge bypass mainly for freight transport will be constructed, where a new Railway Complex will be located. The section includes one viaduct, five underpasses, eight overpasses and a pedestrian footbridge. The most unique distinctive structure is the Los Tramposos Viaduct, with a total length of 1,130 metres.
Construction works for the freight yard of the railway complex and its connection to the Valladolid rail arterial network (Spain). Execution of the freight terminal of the railway complex of the new arterial network. It includes a set of tracks for train arrival, departure and formation, as well as a loading/unloading area consisting of a 750‑metre‑long concrete slab.
Double‑tracking of the Barcelona R‑3 suburban line. Parets del Vallès – La Garriga section. Track and electrification works. Double‑tracking of a 16‑kilometre section, including the construction of the trackbed and track, structures (9 viaducts, 7 overpasses, 9 underpasses, 28 retaining walls), drainage works (19 drainage structures, ditches, collectors), electrification (masts, overhead contact line, etc.), railway systems on the trackbed, and the reinstatement of affected easements and services.
Undergrounding of the R2 suburban line of Renfe in Montcada i Reixac (Vallès Occidental, Barcelona, Spain). The project includes the construction of the municipality’s new station and will represent an unprecedent urban and railway transformation, given the diversity and technical and construction complexity involved.
Comprehensive remodelling of Fuente de San Luis Station for the implementation of standard‑gauge track (Valencia, Spain). The project includes the renewal of the mixed‑gauge superstructure or its adaptation to this gauge where it is not yet present on the main line and in much of the track yard. It also includes works for the creation of new trackbed to extend siding tracks or connect existing tracks, as well as the upgrading of drainage, electrification, railway systems, utilities and easements, and auxiliary installations to suit the station’s new track layout.
New Sant Feliu de Llobregat Station and railway integration in Sant Feliu de Llobregat. The works include the outfitting of the interior of the infrastructure designed for the new underground station, as well as the construction of a new surface access building and the urban development of its surrounding access areas. The project also includes the implementation of civil protection and safety systems for the new station and the access tunnel.

The extension comprises 1,747 metres in which the alignment crosses over the existing Metro Line 8 and beneath two motorways. The tunnel is constructed using mined methods (Madrid Method) and between diaphragm walls. In addition, the existing T1–T2–T3 station is being expanded to convert it into an interchange between Lines 5 and 8.
> Metro and Metropolitan Infrastructures. International.
