Metro station at Amsterdam CS

In the centre of Amsterdam, under Amsterdam Central Station (the building is a national monument), work is being carried out on a metro station and part of the North/South metro line. One unique innovation in this project is the pre-dredged trench under the station yard, which has created a temporary canal under Amsterdam Central Station.

Project

Onderwater Techniek Nederland (OTN) did all the diving work for this pre-dredged trench. Amongst other things, OTN removed the old wooden piles, assisted during the earthworks by making inspection dives, took soundings, spray-cleaned the sheetpile wall and poured underwater concrete. OTN also carried out construction work underwater, performed various welding jobs and the OTN divers assisted when the tunnel element was being immersed under the station.
