Place the rig around the recognized pile point. Look at the precision of the point by comparing it with other reference points.

When driving via dense materials, open-ended piles may well form soil plugs which could make the pile act just like a shut close pile and boost the pile toe bearing capacity significantly.

Massive pile measurements can be used for wind turbines and pylons, river bridge foundations, bridge abutments and piers, maritime construction

Withdraw the tremie pipe within the borehole because the concrete degree rises. This can be to facilitate the flow of concrete. On the other hand, it can be crucial to notice that the tremie pipe would be to be embedded not below 3m underneath the concrete degree.
