What engineers say
Dr. Peter K. Robertson
Professor Emeritus, Geotechnical Engineering
“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.”CPeT-IT
Andreas Giannakogiorgos
Senior Principal Geotechnical Engineer at Tetra Tech Coffey
“It is an absolute pleasure to use Geologismiki’s software for my everyday geotechnical work. Far more important than the superb quality and value for money is the technical support, the constantly updating process and additional tools installed.”CLiq
Dr. Jonathan D. Bray
Faculty Chair in Earthquake Engineering Excellence, UCB
“An intuitive, powerful tool for examining CPT results in practice, research, and education; enhanced by incorporating Peter Robertson’s extensive CPT knowledge.”CPeT-IT
Ron Ebelhar
Senior Principal at Terracon Consultants
“CPeT-IT is by far the best application I’ve found for analyses of Cone Penetration Test (CPT) data. The user interface for data input is easy to learn, and the variety of outputs and ability to customize reports is very powerful.”CPeT-IT
03 / Licensing
The right fit for your practice.
All GeoLogismiki licenses are subscription based.
Renews every year
Subscription license
An active subscription for one year, renewed annually to keep using the software.
Renews after 5 years
Premium license
Comes with 5 years of active subscription, so renewal is only needed after 5 years of use.
License types
Node-locked license
Tied to a single computer, for the engineer who runs the software on their own workstation.
Floating license
Not tied to one computer. It can be used on different machines, and one license key can hold many license seats, so a team can share the software with as many people working at once as there are seats.
