This Dynamic Load Testing and Pile Driving Monitoring system is based on the High Strain Dynamic Load Tests method, also called the PDA test. The GPC PDA system also evaluates shaft integrity, driving stresses, and hammer energy when monitoring the pile-driving installation.

The GPC system comes with the N-GAPA software used for pile load analysis and signal matching.

It helps estimate the total bearing capacity of a pile or shaft and the resistance distribution along the shaft and at the toe. The GPC system monitors the pile on-site, and N_GAPA software is used for analysis afterward. N_GAPA has been proven to perform similarly and faster than CAPWAP.
