Pile Driving Analyzer | PDA Test

This video visually explains the process of PDA test on piles.
Dynamic Load Testing or PDA testing, is a fast, reliable and cost effective method of evaluating foundation bearing capacity.
In addition to bearing capacity, Dynamic Load Testing provides information on resistance distribution (shaft resistance and end bearing) and evaluates the shape and integrity of the foundation element.
Accelerometers and strain transducers attached to the foundation measure force and velocity as the drop weight hits it. Instead of strain transducers, SSG may also use a force transducer, which speeds up the test and in certain cases may yield more accurate force measurements.
Dynamic Load Tests are standardized by ASTM D4945-12 Standard Test Method for High-Strain Dynamic Testing of Piles. The test may also be configured to meet the requirements of the Rapid Load Test standardASTM D7383 provided an adequate ram is available.
