The aim of the study is to develop new methods for environmental construction monitoring. A drone will be used to provide images of the perimeter actually used and information about the impairments caused. In addition, the study deals with the environmentally friendly implementation of demolitions and new constructions of facilities in connection with the 2017 Ski World Championships. The aim of the work is to ensure that the legal requirements for environmental protection are complied with in construction projects. During the construction phase, the greatest possible protection of nature and landscape, soil and water will be ensured. Special attention will be paid to the alpine habitats.
