In the scope of this paper the design of the foundation for a 17-storey hotel with an adjacent 4-storey office building is presented. The subsoil comprises of limestone with caverns and residual soils as a result of the leaching of gypsum and anhydrite. To ensure the serviceability of the foundation, soil improvement by means of compaction grouting has been carried out in the leaching zone. The results of geotechnical and geodetic measurements, which are carried out to monitor the performance of the foundation, are presented.
