Project information

Tunnel sections for the North-South Line

Strukton/Van Oord started by making room for the new North-South Line tunnel section, which will run directly under Amsterdam Central Station. As this section replaces part of the existing foundations of the station hall, the contractors have constructed an extra layer of steel piles that bear a large share of the load previously borne by the old foundations.

They then proceeded to excavate the trench for the new tunnel section leading under the station hall. This temporary enclosure was flooded and opened up to the nearby IJ, so that in July 2011, the contractors were able to transport the first section underwater to its location below the station and move it into position. The remaining three tunnel sections were then immersed in the IJ itself in the course of September and October 2012, resulting in a new underwater link between North Amsterdam and Amsterdam CS.

CS underground station

To ensure the North-South Line connects effectively to Amsterdam Central Station’s public transportation hub, Strukton/Van Oord are also working on the construction of a new underground station deep below the square in front of the station hall. The contractors started by erecting a roof structure over the building site, so that inconvenience for travellers in and around Amsterdam CS is kept to a minimum during construction and excavation work.
