Groundwater level is at approx. 3 m below ground surface.

Technical Data

Construction of 2 building pits for the new buildings of the faculty Mathematics and for Modeling- and Simulation Research at the Technical University of Berlin.
The lot „Ground Engineering“ contains the following essential work:
• Sheet pile approx. 6,000 m²
• Strand anchors approx. 300 Stück
• DSV-Invert approx. 7,000 m²

Furthermore the work includes:
• work planning
• minimal earthwork (work levels, advance excavation, disposal etc.)

Main excavation work and drainage were tendered and awarded in a separate lot.

Difficulties arise from:
• Inner-city location
• additional, not precisely defined interfaces to the lot „earthwork“
• insufficient planning lead time (missing approval for detailed design, incomplete tendering or rather no tendered services
