Hazards Resulting from Improper Building Drainage System By the Use of BIM


This article studies hazards arising from the improper use of dewatering methods to prevent underground parts of a building. The analyses were carried out on the example of a residential building with an underground garage. Groundwater began to appear in the underground garage, after the building was used for several years. Some protections were deployed to limit the ingress of water into the building, which proved to be ineffective. Improper use of the wells to lower the groundwater level around the building led to visible scratches on the external walls and foundation slab. The article applied building information modelling (BIM) to provide information about the analysed building and to analyse further the possible hazards arising from the drainage methods used.
