Two tunnels of 4,800m length each. The Fire Extinguishing Design was prepared in accordance with ERGOSE / EX.288601 / 17.02.2017 which requires a fire extinguishing network with fire hoses per 100m of 400 lt / min supply and simultaneous operation of 2 fire hoses. The network is common to both tunnels with simultaneous loop operation. Consideration was given to the creation of two separate pumping stations (instead of one) in each exterior service building, to ensure supply from two sources for safety reasons and to minimize pump gauge height.
