The Sinking of the Amsterdam Metroby David Halperin, Freelance Writer; Amster, The Netherlands,
Serial Information: Civil Engineering—ASCE, 1975, Vol. 45, Issue 9, Pg. 92-95
Document Type: Feature article
Subway construction was not practical in Amsterdam, The Netherlands, until this new placement technique. Most of the buildings in Amsterdam rest on old, untreated wooden piles that would deteriorate if the high water level were lowered for most conventional subway construction methods. Therefore, the tunnel segments for Amsterdam's new Metro are constructed on the surface and then allowed to settle into their submerged final position with aid of hydraulic excavation by water jets and slurry pumps.
