Bauer has said that it expects to complete special foundations work for a deep basement on a new office complex in Munich, Germany this month.
The 7,500m2 Karl development, which was designed by UK-based architect David Chipperfield, features a two level basement formed by Bauer using an anchored wall.
Before starting work on the new foundations, Bauer had to bore out 380 locations to 10m depth to remove old foundations and installed a dewatering system to manage groundwater during the project. The contractor had to deal with obstructions from the previous use of the site including old sheet pile walls and buried steel girders.
The basement wall was formed using mixed in place techniques and the 550mm diameter columns were formed to 15m depth. The wall has been secured with four layers of anchors, which are between 15m and 21m long, to allow the wall to take the high loads expected from the development.
