Abstract
The problem of facade destruction is particularly acute in the historical center of St. Petersburg. Due to the uniqueness and cultural value of buildings in this area, the preservation and restoration of facades are priorities for city authorities and experts. In their work the authors suggest using 3D scanning to obtain more accurate data on the condition of facades. This method provides performing a detailed three-dimensional model of a building. It significantly reduces the time and cost of monitoring, and allows one’s to assess the facades state. To evaluate the effectiveness of the proposed approach, we conducted the experimental research on the case study of one of the historical and cultural buildings of St. Petersburg – the Apartment House of A.L. Lishnevsky. The results of the study demonstrated that 3D-scanning technologies provide operational control of the damage and accident rate of facades. Also they can facilitate the conservation and restoration of buildings located in the historical centre of St. Petersburg.
