Study of the Adequacy of the Bim Model in the Survey of Damaged Building Objects

The article examines approaches to determining the adequacy of the BIM model when surveying construction sites that have suffered as a result of hostilities. In particular, it has been determined that the inspection of construction objects and structures damaged during aggressive influence, in particular combat operations, requires the development of special measures for conducting the inspection. The process of the actual condition of the construction structures of the structures under investigation, taking into account safety measures, including the danger of collapse of structures or structures, the presence of explosive substances and means on the territory of the survey, the presence of harmful construction materials on the sites, etc., requires significant attention. Modern methods of inspection of buildings and structures determine the periodicity of work, which usually takes into account the specifics of the object, its actual condition and expert recommendations of a specialist. Such approaches are justified under normal operating conditions of construction objects, but are not effective in the presence of variable factors caused by external influences, such as military operations or natural disasters. Analysis of the state of buildings and structures, as well as their structures, is proposed to be carried out discretely to form a picture of changes in their state over time. The degree of discreteness is determined by the expert. Conducting an initial survey of building structures using remote monitoring allows you to form an information database about the state of these structures. Means of remote monitoring, in particular, UAVs, make it possible to obtain the accuracy of studies of the state of structures within 20 mm. Such values are not exhaustive, they allow to determine only generalized parameters, for example, the scope of work, the implementation of monitoring of the execution of related works, etc., therefore, at present, the search for methods and means of remote monitoring is being carried out to increase the accuracy of measurements for the study of cracking of structures, exact deviations of structures from design, etc. Modern software tools make it possible to create intermediate 3D models of objects using photogrammetry methods during geodetic research. Comparative analysis of simulation modeling of construction objects and their cartographic analysis allow to adjust the BIM model of the object for the development of measures to restore its operational state or disposal or conservation.
