Numerical Modelling

Geotechnical modelling of complex engineering projects supported by 50 years of professional experience

Numerical modelling of geotechnical problems is nowadays an essential tool for solving complicated geotechnical issues or routine assessments as well. Numerical analyses are often irreplaceable for delivering of recommendations and final conclusions. They are highly effective and economically favorable especially in the first phases of project allowing to set final hypothesis of geotechnical issues without financially and time-consuming procedures. For numerical calculations, we use several software systems developed by world-class companies. We usually apply Czech standards or Eurocode, but we also provide solutions in accordance with German, French or other standards, compatible with the clients’ requirements. Numerical modelling of complex geotechnical issues.
