Foundation inspections are carried out following excavation but prior to pouring concrete to confirm that ground conditions and geotechnical properties are the same as those to which the foundations have been designed.
Foundation inspections might be carried out where ground conditions are particularly variable, where unexpected ground conditions have been encountered, where the bearing capacity is particularly critical and/ or where an inspection might result in less conservative foundation design/ construction.
Foundation inspections might include in-situ testing, e.g. hand shear vane or plate bearing testing.
A bearing capacity will normally be provided. Re-design of foundations is sometimes necessary/ recommended.
