Main GPC Review software screen

The program window is divided into 4 parts:
- Left Panel: Pile information
- Middle Top Panel: Waveforms: F-V, Fi, WU/D, or Vi waveforms.
- Middle Bottom Panel: Blow parameters and results
- Right Panel: Vertical plots
  - RU: Resistance plot.
  - STR: Stresses plot
  - EMX: transferred energy and hammer stroke heights.
  - RBD: Pile rebound estimate (at top and toe of pile)
  - ENV: Envelopes along the pile lengths:
    1. Tension stresses within the first 2L/c per CASE method
    2. Tension stresses per N_GAPA signal matching program.
    3. Compression stresses per N_GAPA signal matching program.
    4. Skin friction (side resistances) per N_GAPA signal matching progra

N_GAPA signal match analysis software􀀃

It is the analysis software for dynamic pile testing,

Comparable to and better than CAPWAP*.
Estimates
- Total bearing capacity of a pile or shaft
- Resistance distribution along the shaft and at the toe.
It is easy to use and super-fast.
Works in REAL TIME

N_GAPA and CAPWAP results are the same

On the right are test results using the GPC system with CAPWAP vs. GPC

Results with N-GAPA using the same pile simultaneously.
The results show a strong correlation between N_GAPA and CAPWAP* analysis software.
