Tampere University (TAU) has implemented an extensive research program for soil testing in Finland. This research project aims firstly to collect data from high quality in-situ and laboratory tests to form a large database on soft Finnish clays. Secondly, the focus has been to derive CPTu correlations for the strength and deformation properties specific to Finnish clays. The collected database is used in this study to investigate the variability in CPTu borings made into soft Finnish clays, in order to evaluate the measurement uncertainty in CPTu tests. Four different clay sites, each containing three CPTu borings, were chosen from the database. The variability in measured cone tip resistance and pore pressure have been analyzed for each CPTu boring. The results show that the repeatability of the CPTu is very good and the obtained coefficient of variations (COV) for separate borings as well as each site are moderately low. This indicates low measurement uncertainty in measured CPTu data, when the tests are done with care.
