Structural changes taking place in buildings and structures due to the passage of time are a normal phenomenon. However, the building objects are also adversely affected by atmospheric conditions or violent natural phenomena. Every year, our surroundings are increasingly attacked by extreme weather phenomena such as: floods, hurricanes, heavy storms with rain or extreme heat. Such phenomena are natural elements of nature, however they significantly interfere in the technical condition of the building. They often cause measurable economic losses: flooding, cracks, construction displacements and even their total destruction. At the time of estimating losses, calculating the costs of repair, and then making decisions about the method of restoration, a helpful tool can be laser scanning: terrestrial, airborne or mobile, depending on the character of the object and the size of the disaster. The paper presents an identification of defects and hazards in structures based on the point cloud using the OptD method.
