Various problems in geotechnical Engineering can be investigated by the program GEO Tools. The original version of the program GEO Tools in GEOTEC Office was developed by Prof. M. Kany, Prof. M. El Gendy and Dr. A. El Gendy to calculate the settlement and bearing capacity of single pile or pile wall according to DIN 4014 (edition 03/1990) and to draw the results in diagrams according to the German Code.

After the death of Prof. Kany, Prof. M. El Gendy and Dr. A. El Gendy further developed the program to meet the needs of practice. The development includes the interpolation between the table values of standards DIN 4014 and EA-Piles, the expansion of the user interface for data input, and additions to the printed output. User friendly interface for defining data or present results is also developed. Furthermore, many changes were carried out to the graphical output. The tables in the text output were also redesigned. The concrete design of the pile cross-section according to different standards was integrated into the program.
