3. 1.0 INTRODUCTION Pile cutting or Cut off Pile   refers to the process of trimming or levelling the upper part of foundation piles, either to a predetermined elevation or to remove damaged portions. This procedure is crucial in ensuring that the pile head is prepared to receive structural connections or to fit into other parts of the foundation system, such as pile caps or beams

4. 2.0 PILE CUTTING PROCEDURE 2.1 Excavation Pile Cap to Cut off Level Formation Before excavation , the pile cap area shall be marked on the ground after conducting a survey work (Control points and As-built drawing) The excavation work carry out by using a machineries such as excavator and backhoe, the manual excavation is also require to remove the earth/soil in between the pile group. After excavation , the pit levels & pile cut off level shall be verified for correctness to the drawings and recorded.
