The term ‘over excavation’ refers to excavation that goes beyond that which is required for the formation of a below ground structure.

This might be necessary for example if the ground conditions at the level that the below-ground structure will be constructed do not have sufficient stability or load-bearing capacity to support that structure. In this case the excavation must be taken to a deeper, more stable level, the unsuitable material removed, the ground at the lower level may need to be treated to ensure it has suitable load-bearing capacity, then the excavation back-filled to the required level with suitable compacted fill.
