Abstract:

About the building works on the metroline U5 in Berlin-Mitte

In March 2012 preliminary building works on the metroline U5 in Berlin-Mitte started with the construction of the first diaphragm walls. This metroline intends to close the gap between the existing metro stations Brandenburger Tor and Alexanderplatz. The new rout section will improve the accessibility of main destinations around Museumsinsel, Straße Unter den Linden and of the government quarter for tourists as well as for citizens of Berlin. Furthermore it offers a direct connection from the aforementioned places of interests to the central railway station.
Structural remains and foundations of past epochs, poorly graded sands, zones of marly till, stones as well as a high groundwater level of around 3 m u gsf form the underground conditions of the project area. The glacial subsoil, which is typical for the galcial valley of Berlin, poses a great challenge for planning and execution of construction pits and tunnel excavation.
Spree and Spreekanal at both sides of the Museumsinsel as well as buildings, historical foundations and the Humboldtforum, which is already under construction, have to be crossed underground by the metroline. Furthermore construction pits, accomplished before, but not deballasted and excavated at the moment of undercutting have to be crossed as well as fault lines around retrieved anchors and sheet piles
