This paper describes how a geotechnical database may be generated from the information system (IS) of a geotechnical consulting company established in compliance with the ISO 9001, ISO 17025 QMS standards and Eurocode 7. The application of these principles is illustrated using a geotechnical consulting company Geokon of Zagreb, Croatia as an example. An overview of Geokon’s geotechnical data management system is presented by describing the  procedures for data input, maintenance, use, expansion and upgrade. Included in this paper are relevant flow charts and a hierarchy of both geotechnical databases and other databases.
