This paper presents the application of geoelectrical tomography with a Wenner electrode array to characterize the subsurface conditions at the site of a planned commercial building in Kakanj. The geoelectrical surveys provided insight into the distribution of soil electrical resistivity, enabling the identification of layers with differing physical and mechanical properties. Most electrical resistivity values were below 700 ?m, suggesting the presence of saturated fine sediments and clays. However, in the central part of the profile, at a depth of 10?15 meters, an anomaly exceeding 10,000 ?m was detected, potentially indicating solid rock masses, concrete structures, or unconsolidated material. The results provide a valuable basis for foundation design. Supplementary investigations, including exploratory drilling and laboratory testing, are recommended to better define foundation conditions and reduce geotechnical risks.
