STUDY OF THE TECHNICAL CONDITION OF THE HISTORICAL BUILDING-LIGHTHOUSE “ANIVA” LOCATED IN THE SAKHALIN REGION
Currently, many historical buildings have not been inspected and there is no reliable information about the technical condition of such objects. Very often, the inspection of the technical condition of structures is estimated only from the outside and does not determine the protective properties of building materials and the internal parts of the building, this is especially important for historical buildings. Therefore, before builders make any design decisions, it is necessary to understand the current state of the object. Several methods can be used to examine it. For example, to find old project documentation, according to which it was possible to study everything indirectly. However, such information will not be reliable, therefore, the complex historical building-lighthouse “Aniva” was taken as a basis, which had to be inspected on site. Lighthouse “Aniva”-an architectural structure with an interesting, complex shape, digital technologies were used for the examination. The article presents data on the survey of this historic building, erected in 1938, as well as the technologies for measuring the parameters of the building when examining the technical condition. As a result, the method of laser scanning and the construction of digital models of structures is suggested for the examination of such buildings. The material is addressed to all interested specialists.
