The article is devoted to the conditions and tasks of the methodology of adaptation and preparation of information models of buildings and structures for subsequent implementation and effective application in the system of technical operation of the building. The following issues are addressed: analysis of the use of BIM-model at the operational stage; analysis of the difficulties encountered when using unprepared BIM-model in operation; synthesis of existing and development of alternative recommendations for filling the information model with data at each stage of design and construction for subsequent use in the operation service; the study of tools that help in the preparation of BIM-model; development of algorithms that optimize the preparation of an information model for the operation of an object.
Keywords: BIM-technologies, information modeling, construction, 3D-model, virtual copy, construction
