Witteveen+Bos has been involved in work on Amsterdam's new North/South metro line since mid-1994. The decision to build the underground line was taken by the client, the City of Amsterdam, on 27 November 1996. Construction began in 2003 following a period of detailed preparations. The line is due to go into service in autumn 2017.
A consultancy called Adviesbureau Noord/Zuidlijn V.O.F. was established in 1994. At that time it was a collaborative venture of Witteveen+Bos and Weger Architecten- en Ingenieursbureau (which later became part of Royal Haskoning). The consultancy subcontracted some work to Ingenieurs Bureau Amsterdam (IBA) and DB International. With Witteveen+Bos as its lead member, the consultancy advises the City of Amsterdam and is responsible in the North/South Line project for the planning study, design, contract preparation, engineering and supervision of work. Adviesbureau Noord/Zuidlijn V.O.F. is now a joint consultancy of Witteveen+Bos and Royal Haskoning.
Numerous developments have occurred since this complex project started. Some have attracted media attention. Communication on the project is handled by a central communication department of the City of Amsterdam’s North/South Line Office. The communication arrangements were agreed in the past with the parties concerned. For the latest news and background information about the project we refer you to the website of the North/South Line, which is in Dutch.
From an engineering point of view, the construction of an underground metro line in Amsterdam's historic inner city is highly challenging, not least because boring must take place in weak clay and because some stations are situated more than 30 metres below ground. The need for innovative and reliable solutions is ever-present. Witteveen+Bos is proud of its contribution to this unique project.
