GPC

The PDA system from Piletest
with N_GAPA signal matching software 

Overview

​

The GPC system is the Pile Driving Analysis - PDA from Piletest.  

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

PDA tests are carried out by driving a hammer on pilot or production piles to take advantage of its high-strain impact while monitoring the pile with an accelerometer and a strain gauge. It is often recommended that re-strike PDA tests be performed. These are the fundamental aspects of the PDA test method. A drop weight can impact the pile if no driving hammer is available on the site.

N_GAPA

A software that is 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 proven to be similar to and better than CAPWAP.

  • N_GAPA can do real-time analysis at the test site during the pile installation.

  • N_GAPA - Complementary to GPC with no extra cost.

GPC PDA system advantages 

  • Easy to use

    • Single bolt per sensor on the pile on Comboducer 

    • Comboducer - One sensor includes an Accelerometer + Strain-gauge 

    • Results analysis can be done on-site using the easy-to-operate N_GAPA software.

​

  • Complementary signal analysis software - N_GAPA

    • Proven to be equal to and better than CAPWAP

    • Real-time signal analysis as you hammer the pile

​

  • Industry Standard 

    • ​It is proven to have the same performance/results as CAPWAP compared to the same pile.

    • Compliant with ASTM D4945 and EN ISO-22477-4

Comboducer - One sensor includes Accelerometer + Strain-gauge
Easier and Faster to install on the pile or shaft.

  • All included 

    • GPC connects to any PC via wireless WiFi. It will also connect to future computers, while embedded systems quickly become outdated. The complete software suite runs on any PC.

    • Software suite includes 

      • GPC Acquisition — For collecting the sensor data and presenting real-time driving plots

      • GPC Review — Reporting of test results and capable of automatic signal matching

      • N_GAPA—An Automatic Pile Analysis software for signal matching analysis. It has been proven to be faster and equal to CAPWAP.​
