Below, a selection of some of the largest projects in execution.
Railway contracts in Romania (Romania). Rehabilitation of the Brasov railway line - Simeria section Sighisoara - Atel. Rehabilitation of the Brasov railway line - Simeria section Atel - Micasasa. Rehabilitation of the railway line between the border with Hungary - Curtici - Simeria (Romania) section 2B: Barzava - Ilteu. Rehabilitation of the railway line close to Hungary - Curtici - Simeria (Romania) section 3: Gurasada – Simeria.
Access to La Sagrera Station. The works consist of the execution of the access sections to the future La Sagrera Station and the two lines Villafranca-Maçanet and Vilanova-Mataró, which will be placed between screens in the lower level of the same, as well as the platform where the Madrid-Barcelona-French border high-speed line will be located, which is available over the previous ones. The layout of the commuter tracks is depressed at the entrance of the station and returns to ascend to the initial level at the exit of it, while the High Speed line would have a substantially horizontal layout.
Arterial railway network of Valladolid. East by-pass. Railway substructure and civil works. It has a total length of 17.5 km, with 2 branches in the initial section and two provisional links with the current route at the beginning and end of the section. A variant in Iberian gauge will be developed, mainly for the transport of merchandise, on which will be located a New Railway Complex, which will have access in international gauge. The layout in plan with design speed of 160 km / h, runs on the surface along its entire length except in 2 km in which the ground runs underground, being mostly false tunnel. The type section of the platform is suitable for a double track of Iberian gauge with an entree of 4.0 m, although in a zone of 6 km the platform is extended to accommodate a third track in UIC gauge, to be installed in the future. As for the structures, the variant has 1 viaduct, 5 underpasses, 8 overpasses and a pedestrian walkway. The most unique structure is the viaduct of "Los Tramposos", on the N-601 road, with a total length of 1,130.5 meters.
Track duplication of the R-3 commuter line (Barcelona). Parets del Vallés-La Garriga section. Track and electrification. Track duplication in a 16 km section including platform and track, structures (9 viaducts, 7 overpasses, 9 underpasses, 28 walls), drainage (19 culverts for drainage, ditches, collectors), electrification (catenary), railway installations, and restoration of affected services and easements.
> Metro and Metropolitan Infrastructures
Riyadh Metro. Lines 4, 5 and 6 (Saudi Arabia). The project includes the design and construction of lines 4 (yellow), 5 (green) and 6 (purple), which will have 25 stations for which 64.6 kilometers of subway tracks will be required, 29.8 kilometers of viaducts , 26.6 kilometers of underground roads and 8.2 kilometers of surface roads. For the construction of the three lines, two Tunnel Boring Machines of the type TBM (tunnel boring machine), of 9.77 meters in diameter, were used to excavate complete section tunnels. Dhafrah was the first tunnel boring machine to start operations and Sanah was the first to reach a station. Currently, 80% of the project's progress has been achieved, obtaining constructive milestones that are relevant to the proper development of the infrastructure.
Lima Metro. Line 2 and branch line 4 (Peru). The project includes the design, construction, financing, operation and maintenance of Line 2 of the Lima Metro and a branch of Line 4, which will reach the airport, for an amount of 3,900 million euros. Line 2 will have a length of 27 kilometers and will cover the east-west axis of Lima, from Ate to Callao. Once in operation, will serve more than 600,000 people a day, which will save up to ninety minutes on its journey. For its part, the branch line 4, which will link the Peruvian capital with the airport, will run along 8 kilometers of tunnel, from Faucett avenues to Nestor Gambetta.
Metro of Madrid (Spain). Maintenance. Maintenance actions consisting of replacement of track devices, substitution of support system and rail fixings, rail renewal, substitution of sleepers, track ripple, geometric corrections on the track in various lines in operation until 2025. The scope of this maintaining covers approximately 50% of the Madrid Metro Network.
Project to improve evacuation and ventilation conditions in the event of fire in the Sol underground train station (Madrid). The project includes a series of actions that will significantly improve safety conditions in the event of fire in the platform cavern at Sol Station. In the first phase, a physical sectorisation will be made between the platform cavern, tunnel and the station hall, technical rooms will be fitted out as evacuation exits and shelters for people, and new fire protection equipments will be added.
In a second phase, a new vertical evacuation shaft and new emergency/evacuation exits will be built (1 at street level, 3 on platforms, 1 in the gallery connecting Sol Suburban Station with Gran Vía Metro), together with the underground evacuation galleries connecting these new exits.
