Summary
Machine-generated summaryHelen Sähköverkko Oy is procuring the excavation and construction of a rock tunnel about 4.2 km long for a future 400 kV cable connection between Sörnäinen and Vanhakaupunki in Helsinki. The tunnel has a cross-section of about 25 m2 and runs mainly at depths of 20 to 53 metres below sea level. Vertical shafts will be built at both ends, at the Hanasaari energy block in Sörnäinen, where the soil above rock is about 20 m thick and contains contaminated soil, and on exposed rock in Vanhakaupunki. Excavation proceeds via two existing access tunnels. The works include building both shafts to ground level, temporary and permanent retaining structures, and around five pump stations, aiming for a largely maintenance-free facility.
