CPeT-IT v.2.0 – CPT interpretation software

Your one tool for CPT interpretation & presentation

” GeoLogismiki have produced an excellent CPT interpretation software package that is easy to use and provides the user with colourful plots and detailed output of a wide range of geotechnical parameters. CPeT-IT is excellent value for money and is highly recommended for anyone that is using CPTU results. “

– Dr. Peter Robertson, Gregg Drilling and Testing, Inc.

CPeT-IT is an easy to use yet detailed software package for the interpretation of Cone Penetration Test (CPTu) data. CPeT-IT is the result of a collaborative effort with Gregg Drilling Inc., a leading company in geotechnical site investigation and cone penetration testing (CPT) and Professor Peter Robertson, co-author of the comprehensive text book on the CPT. We strongly believe that CPeT-IT should belong to your arsenal as your CPT interpretation software.

CPeT-IT takes Cone Penetration Test raw data and performs basic interpretation in terms of Soil Behaviour Type (SBT) and various other geotechnical parameters using the current published correlations based on the comprehensive review by Lunne, Robertson and Powell (1997), as well as recent updates by Professor Robertson.

The cone penetration test (piezocone CPTU) test is one of the most versatile tools for soil exploration in existence today. The piezocone and associated pushing equipment provide continuous measurements, excellent repeatability and is cost-effective. Throughout the last few decades, considerable knowledge regarding the use and interpretation of the CPTU has accumulated in the geotechnical community. CPeT-IT makes use of this knowledge and provides a fast, easy to use tool for Geotechnical Engineers to interpret and plot CPTU data.

File Converters

Below you may find download links to some converters for the most commonly used data formats. The converters will read the input data files and create .cor files that can easily be imported into CPeT-IT.

Hogentogler digital sounding file converter

You may download a simple software to convert Hogentogler sounding files to .cor files so you may easily import them in CPeT-IT. The Hogentogler file structure is the one generated from the Hogentogler EFCS4 computer system.

GeoExplorer Gorilla sounding file converter

You may download a simple software to convert Gorilla sounding files (v.7.1 specs) from GeoExplorer to .txt files so you may easily import them in CPeT-IT. The converter will export penetration data (depth, qc, fs and u2) as well as any dissipation test included in the file.

Geotech/Geoprobe CPT sounding file converter

You may download a simple software to convert Geotech/Geoprobe CPT sounding files to .txt files so you may easily import them in CPeT-IT. The converter will export penetration data (depth, qc, fs and u2).

You may contact us if you need support for importing different file structures to CPeT-IT.

  • CPeT-IT has been tested on IBM compatible machines using Windows® 2000, XP, Vista and 7 operating system
  • CPeT-IT uses about 2.0 MB of disk space
  • CPeT-IT requires GDI+ library (included in Windows® XP) which can be freely downloaded.
  • A 17” monitor is recommended for better performance.

This webinar provides worked examples of CPT-based liquefaction analyses using the software CPeT-IT v.2.0. Presenter of the webinar is Dr. Peter K. Robertson, Technical Adviser at Gregg Drilling and Professor Emeritus at the University of Alberta. To view the webinar click the here.

Another webinar we strongly suggest you to watch is the one on CPTu dissipation tests. This webinar is focused on providing an overview on pore pressure dissipation tests using the CPTu – from theory to practice with some worked examples using CPeT-IT.
