FCC Construcción and Convensa have been winners of several Foundation Caminos 2023 Awards.

The Albert Serratosa City and Territory award in its 5th edition has been awarded to the project: Remodeling of Plaza España (Madrid). In turn, Segovia Aqueduct Award for Public Works and Environment given by College of Civil Engineers: High Speed Galicia  has been given for the construction of the infrastructure corresponding to the Bolaños tunnels, Vilariño-Campobecerros Vía Izquierda section.

The reform project of the Plaza de España in Madrid had the objective of recovering the square as a place to stay, civic and active; reducing motorized road traffic and increasing pedestrian spaces; increasing the spatial continuity between the square and its surroundings and connecting its green areas, especially with the Plaza de Oriente, the Sabatini Gardens, the Parque del Oeste and the Temple of Debod as well as with Madrid Río.

With the project, the continuity of these magnificent public spaces previously segregated due to the infrastructures built in the 1960s has been recovered. In addition, universal accessibility and environmental improvement have been guaranteed through the protection and increase of vegetation, and coordination with sustainable mobility systems.

This is the largest urban regeneration project developed in Europe in the last year.

The construction of the infrastructure corresponding to the Bolaños tunnels, Vilariño-Campobecerros section involved the construction of two parallel single-track tunnels of the Madrid-Galicia High-Speed Line, with a length of 6.7 kilometers each.

With average excavation yields in the first tunnel of 19.40 linear meters per day, it has been completed in 11.5 months. The drilling of the second tunnel has had an average excavation performance of 24.32 linear meters per day, which has meant complying with a 9.5-month execution period. All this has led to a reduction of two months with respect to the time invested in the first tunnel.

For the execution of the tunnels, an R+D+i solution was implemented based on the application of a stabilization system in highly unstable geological terrain. The excavation diameter is 9,900 mm and the useful section is 60.27 m². The tunnel lining was carried out using precast segments 370 mm thick and 1,600 mm long.
