- Synopsis:
-
The course deepens the knowledge from the previous course ZS1. It covers design principles, risks associated with the foundation of structures, deeper design of flat foundations, deeper design of deep foundations, negative casing friction of drilled piles, grouting (calculations and execution), construction pits, improvement of foundation soils.
