Natural History Museum, Basel

In order to remedy the lack of space for the Basel Natural History Museum and the Basel-Stadt State Archives, a new building almost 200 metres long is being constructed at Basel St. Johann railway station.

The location in the city centre between the SBB and BVB railway tracks and the construction process place high demands on the monitoring of the surrounding buildings and infrastructure. The 19 metre deep excavation pit is being constructed in a two-stage process. Firstly, there is a bored pile wall, which is anchored back with three prestressed anchor layers. Secondly, due to the groundwater, a sheet pile wall will be vibrated into the deep area of the pile wall.
