Expansion of underground network in Amsterdam; construction of north-south line
ARGE Saturn (DuraVermeer and Züblin)
The NordZuidLijn will be a new underground railline crossing Amsterdam from north to south.Amsterdam is situated at sea level, with many canals running through the city and historic sites that require protection. For these reasons, the lowering of the ground water during construction work must be carefully planned; this applies in particular during the building of the Rokin, Vijzelgracht and Ceintuurbaan stations in the city centre. Completion is expected to be in 2013.
KTZ and KTV series pumps lower the groundwater during construction work on the underground stations and tunnels. Multiple pumps are kept on standby or are in mobile use.
