In the context of the general trend to accelerate change, the life cycle of a construction object, analysis and design of its stages becomes an actual object of scientific research in the field of construction. The subject of the study becomes the information model of the life cycle of the building. It is studied and modeled on the basis of the concept of real estate development and using the methods of project analysis of the construction project. With the help of BIM-modeling tools, mandatory

... stages and possible phases of the life cycle of a building object can be represented as hierarchically and sequentially related information flows, in which the attributes of each stage of the life cycle are formed under the influence of the preceding stages and of special factors for the considered stage. On this basis, an analysis of the characteristics was carried out, and the structure of simple and complex construction works was developed, which allows determining for each stage of the life cycle of a construction object: interconnection of information flows, composition and content of the information model of the building required for the work of specialists.
