We are conducting construction site supervision for the “Basque Country High‐Speed Rail. GipuzkoanBranch. Hernialde Zizurkil Section2” that is a part of the branch managed by the Basque Government. This project involves site construction supervision of the complete infrastructure through to termination of the deck (laying and compacting of the under‐ballast layer), in suitable condition to take the superstructure which will enable operation The work to be executed is 5.87 km in length, of which more than 85% (5.14 km) runs through tunnels (Anoeta Tunnel 1.39 km, Asteasu Tunnel 2.6 km Ugarte cut‐and‐cover tunnel 268 m and Zizurkil Tunnel 879 m).
The section also includes 3 viaducts with a total length of 498 m, of which the longest, at 404 m, is the Asteasu bridge. The orientation of the rail line is mostly South‐North.The infrastructure is designed for mixed traffic, with a running speed for passenger units of 250 km/h.
