Pile Driving Analyzer (PDA) System
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

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.
