Main Acquisition software screen

  • Four (4) different graphs on one screen

  • Fi, VZi, F&V, WU&D, presented in L/c scale

  • Live capacity plot, presenting soil resistance per each blow

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.
