Dynamic Pile Test (PDA)


This test provides the strains and accelerations present within a pile during driving operations. Strain and acceleration data from the test can describe the pile driving stresses and compression, transferred energy and the contribution of shaft friction and toe resistance to the load bearing capacity. Driving records are immediately available to assist in optimizing foundation installation through accurate selection of final driving depth. This method can be used for prefabricated piles, cast-in-place piles, steel piles, timber piles and even composite piles.
