Purposes of PDA Test
1. to identify in conjunction with piling records, doubtful piles for investigation or static loading tests
2. to assess the structural integrity of a pile
3. to check the adequacy of the final set criterion as derived from a pile-driving formula
4. to check the consistency of hammer efficiency

Compliant with ASTM D4945-17
Standard Test Method for High-Strain Dynamic Testing of Deep Foundations
This dynamic test method covers the procedure for applying an axial impact force with a pile driving hammer or a large drop weight that will cause a relatively high strain at the top of an individual vertical or inclined deep foundation unit, and for measuring the subsequent force and velocity response of that deep foundation unit. |

The Pile Driving Analyzer (PDA) system is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world.
The PDA eighth generation (PDA-8G) acquires data from accelerometers and strain transducers attached to a pile or shaft so that High Strain Dynamic Tests (ASTM D4945) may be performed. The tests require the impact of a pile driving hammer or a suitable drop weight. |
