North-South Line Immersed tunnel CS

Project description

A major challenge for the realization of the North/South metro line station “Centraal Station,” is its passage with the historic railway station. The platforms for the metro station are located directly under the railway station. The boundary conditions for the design of this station were very stringent since the railway station had to remain in full service during construction in terms of train operation and maintaining the traveller flows. In realizing this passage, a combination of the wall-roof method and the immersed tunnel technique is used. In this way parallel construction was possible and the construction activities at the railway station could be limited.

Scope of Work

The consultancy services included:

  • Technical studies after building pit concept to construct immersion pit
  • Pre-design, final design, tender design and detailed design
  • Tender documentation and consultation
  • Contract management and supervision
  • Alliance steering group management for the construction of the innovative building pit walls
