Technical information for assembly
3.9.1
Foundation
The foundation must reliably transfer existing loads into the subsoil.
Therefore ensure the following points before each assembly job:
Evidence showing the load bearing capacity of the foundation
Evidence showing the load bearing capacity of the subsoil
Since the load capacity of the subsoil is often very difficult to estimate,
a specialist soil investigator should be called on if there is even the
slightest doubt, in particular for high/complicated superstructures.
The following points must be taken into account when assessing the
subsoil:
Permissible maximum ground pressure
Predicted
settlement
Predicted groundwater levels
Predicted thawing and frost processes
Construction activities expected in direct proximity to the installation
site
Steel plates and concrete can be used as load distributing base supports.
The foundation must be horizontal. The ground pressure data includes no
safety factors
