Evaluating the subground properties during the initial stage of a construction of building is important in order to estimate the suitability of soil quality to the tech-nical requirements of bearing capacity, resistance to stress, and strength. This study presented the evaluation of the geotechnical properties of soil intended for the construction of Max IV facility of Lund University, performed in field-work and laboratory. The in situ methods included drilling boreholes, core sampling and assessment, crosshole mea-surements, and borehole logging. The laboratory-based measurements were performed at Swedish Geotechnical Institute and combined seismic measurements of drill cores, determination of the uniaxial compressive strength (UCS), and examination of material property: sieve analysis and natural moisture content. UCS was evaluated with regard to velocities of elastic P-waves. The synchronous light test by X-ray diffraction was performed for qualitative analysis of mineral composition of samples. The study applied integrated approach of the diverse geophysical methods to solve practical tasks on the evaluation of foun-dation strength and geotechnical parameters. This study demonstrated the benefits of integrated seismic and geo-physical methods applied to soil exploration in civil engi-neering for testing quality of foundation materials.
