71 North/South Metro connection in Amsterdam This project concerns the building of a new metro connection between the North and the South of Amsterdam. This project is partly underground, this metro line is even going under the CS of Amsterdam. The drill process starts at Amsterdam CS, in phases a concrete caisson is built and sinks deep in the ground. From there the tunneldrillmachine starts drilling. This caisson is calculated in ESA-Prima Win. The use of building phases was very important for building and sinking the caissons. The geometry is calculated with loads and building phases for variable sub soils. Short Description
