The paper presents tests results of the geotechnical conditions for foundation of the building D of University of Agriculture in Kraków, 116 Balicka Street, which were made because of its planned extension by two adjacent buildings – from the north (A) and south (B). The study showed that the building D is built on a 0.6 m width concrete continuous footing without offsets, within the layer of silty sand. Foundation of both newly designed buildings on continuous footings of 0.60 m width at a depth of 1.20 m (building B) and 1.40 m (building A) in a layer of silty sands was proposed. The calculations showed a high load-bearing capacity of the ground. For design purposes it is proposed to use the ultimate resistance obtained from calculations made according to Eurocode 7.
