Pile Driving Analyzer

Clients can avail from us Pile Driving Analyzer which is the most widely employed system for Dynamic Load Testing and Pile Driving Monitoring in the world. It assesses the capacity of several piles in a single day. The PDA also evaluates shaft integrity and investigates driving stresses and hammer energy during pile installation.

The driving hammer itself is used to perform PDA tests, or High Strain Dynamic Tests, on pilot or production piles. If necessary, it is possible to perform re-strike PDA tests even after the driving hammer is no longer on location, by using a drop weight (see examples) to impact the foundation.

The PDA calculates results from velocity and force signals obtained by sensors (accelerometers and strain transducers) attached to the pile. Sensors may be Smart (transmit data using Wireless Transmitters) or Traditional (transmit data via cable).

Pile Driving Analyzers include the PDA Software Suite, CAPWAPAR and GRLWEAP . CAPWAP analysis of PDA data is essential for a Dynamic Load Test. It provides the soil resistance distribution along the foundation and simulates a static load test. Extensive correlations between CAPWAP simulated and actual static load tests have proven the reliability of this method of determining pile capacity.
