FCC Construcción has completed the boring of the Bolaños tunnels (Verín-Ourense), on the Madrid-Galicia High-Speed Line. The works entail the execution of two parallel single-track tunnels, each 6.7 km long on the line.
With an average excavation performance of 19.40 linear metres per day in the first tunnel, the work took 11.5 months to complete. The boring of the second tunnel saw an average excavation performance of 24.32 linear metres per day, resulting in a completion term of 9.5 months. Therefore, there was a two month reduction with regards to the time invested in the first tunnel.
FCC Construcción has built over 99 km of AVE in Galicia, undertaking unique projects such as the Bolaños Tunnel or the Vigo-Das Maceiras Tunnel with a length of 8.5 km.
