Project - North-South Line Central Station, Amsterdam

North-South Line Central Station, Amsterdam

Project description

In the Dutch capitol Amsterdam, a new metro line is being realised, the North/South Line. Part of this metro line is an immersed tunnel under the existing Central Station. The existing foundation under the station was partly demolished and adjusted to make way for the immersed tunnel. This unique project was realized under very challenging circumstances and often in confined work spaces.

MH Poly advised on the design of the immersed tunnel under the Central Station and designed a guiding system for the safe transportation of immersed tunnel element under the Central Station in a very restricted area.
