Site supervision of the works of 1.300m of road tunnel under one of the most important street junctions of the city of Barcelona. Due to its construction in a consolidated urban area, it is necessary to excavate the tunnels taking into account the high presence of existing utilities and the need to reduce traffic alterations by executing a large number of traffic diversions. The tunnel passes under 4 old railway and metro tunnels, which requires the construction of extremely rigid provisional support methods to reduce possible movements (large diametre steel tubes filled with concrete).
