The present paper focuses on the re-evaluation of archive engineering geological data of sic core drillings at one of the new metro stations of Budapest (Kálvin square, metro line 4). More than 1000 data of total coring length of more than 210 meters were used for statistical calculations. The data set includes index of plasticity, skewness, void ratio, water content, dry and water saturated bulk density, relative humidity, angle of friction, cohesion and compressive strength. Based on the data set the engineering geological description of sediments was reevaluated, and sand, clay, silt and bentonite-rich horizons were identified. Three new crosssections were prepared. Statistical analyses proved that there is an increase in cohesion and density of clays and silts with depth, indicating the role of consolidation.
