In thesis we dealed with BIM implementation in the project of sewage system in the area of Prlekija, more precisely in the area of Podgorci. Using Autodesk software – Urbano Canalis, a 3D BIM model was created. The subject of the project is gravity-pressure municipal sewerage with pumping stations located along the local and municipal roads and in the area of the planned sidewalks, which are part of the second project. At the same time with the construction of the sewage system, the existing water supply system will be reconstructed.
