PDA Test

HIGH STRAIN DYNAMIC PILE TESTING (PDA TEST)

PDA Testing utilizes the Pile Driving Analyzer@ (PDA) and is based on the theory of Stress Wave Propagation on Piles (CASE Method). Force (strain) and velocity (acceleration) measurements taken near the top of a pile during impact provide the necessary information to determine:

  • Activated bearing capacity
  • Hammer performance
  • Maximum driving stresses
  • Pile integrity

PDA Testing can be used on all types of piles, such as concrete piles, bored piles, steel piles and so on. For large diameter bored piles, 4 pairs of strain transducers and accelerometers are used. Many piles can be tested in a day resulting in lower cost.

Results such as pile integrity can be evaluated on site and would allow the engineer to accept or reject the pile immediately. Actual driving stresses and hammer performance data obtained during pile monitoring can reduce pile damage. Piles no longer need to be overdriven, resulting in lower foundation cost.

 

BENEFITS:

  • Tests deep foundation integrity & capacity quickly, reliably and economically
  • Most widely employed system for Dynamic Load Testing and Pile Monitoring in the world
  • Conforms to ASTM D4945
