 Summary:
 This paper covers the reconstruction of the chimney at the heating plant Visnjickabanja (municipality of Palilula, Belgrade) and restoration and reconstruction of the existing foundation of the chimney. The need for reconstruction emerged due to change of the raw material, i.e. the transition from fluid fuel (mazut) to natural gas. The existing chimney is self-contained, standing circular steel structure with external diameter of 1500mm, standing on the two-stepped foundation made of reinforced concrete. With the change of raw material there was the need for three separate chimney pipes, and because of that on demand of the investor, the project of supporting carrier with triangular cross section, with sides of length 3.0 m, was made. With the analysis of the existing foundation structure and based on the existing geotechnical elaborate, it was concluded that the foundation needs to be restored and repaired in terms of reinforcement and expansion.
