The step is performed on both beaten & drilled piles to verify the load-bearing capacity of the piles. The design means that a free-falling weight is released from a certain height. Sensors are mounted on the pole. When the weight hits the pile, a shock wave occurs which goes down into the tip of the pile and turns. In the reflex formed from the shock wave, the sensors can pick up the signal and verify a load. When PDA measurement is performed, it is often done in a range of about 10-25% of the total amount of piles.
