INTRODUCTIONThe technical operation of buildings and facilities is a set of measures aimed at ensuring the normative life of the property.The operating organization faces a number of tasks, from which it is possible to distinguish the following: the correct use of the building's engineering systems, operation and overhaul of the building.Automated methods of collecting and processing data on the physical parameters of these systems are currently being used to properly use engineering systems.Exploitation and overhaul is the most expensive stage of the building's life cycle, accounting for approximately 70% of all costs during its existence. In our country, exploiting organizations inherited a huge housing stock, previously almost entirely owned by the state. Now it, being already in different forms of ownership, requires constant maintenance and overhaul. The situation is complicated by the fact that in the last thirty years, during the so-called "transitional period", almost no major repairs to residential buildings have been carried out, and in most cases technical documentation for buildings is partially or completely absent. LITERATURE REVIEWProfessional real estate management provides an opportunity to optimize the costs of operating and repairing facilities, therefore, in order to improve the efficiency of the building's operation, the information modeling technology of capital construction, repair and reconstruction facilities is now increasingly being used in order to improve the efficiency of the building's operation.This approach, while requiring capital investment, may ultimately reduce labour, financial and time resources, thereby increasing the efficiency of the operating organizations. MATERIALS AND METHODSAccording to the authors, the way to develop the application of BIMtechnologies for professional property management in our country can be formalized as a concept, and highlight the main advantages of this approach.The essence of our concept is to integrate time-changing engineering systems into an operating information model to ensure access to the necessary information about engineering equipment and systems through web applications. The use of a rich information model is expected in various operating organizations involved in the maintenance of buildings. This approach is designed to make it easier for exploiting organizations to achieve their objectives and to simplify their work.The main advantages of the concept are:Current electronic technical documentation, which is accessed through web applications for all participants in the operation stage,Controlling the building's engineering systems in real time by employees of operating companies;The ability to issue a task for repairing or replacing certain equipment online;Remotely monitoring the procedure of necessary equipment repair or replacement by operating company staff;Visual representation of technological equipment locations and navigation of the building;Controlling changes during process of equipment repair/replacement/installation/demolition at object operation time. ResultsThe concept uses information models of capital construction facilities, as the design of such facilities provides the possibility of more complete saturation of models with the necessary information about the building and engineering equipment, and the model itself is more detailed in comparison with the models created during the overhaul.The system for integrating the physical parameters of engineering networks into the building operating model can be implemented via the integration of various tools and services, such as:- Autodesk A360 for cooperative work of various structural departments, for example  maintenance and operations department and supply department;-Data repositories for storing and viewing information-Messengers for communication between different stakeholders in the process while using the information model used;-SCADA systems to obtain engineering equipment parameters from existing facilities at the site.The following tasks will be solved out by the present concept development:-Simplifying the maintenance of buildings during operation;-Ensure that all physical changes made during the building operation are under control;-Ability to get real information about engineering equipment of the object via controlling  the technical parameters by the operating organization;-Accelerate the process of repairing or replacing equipment by remotely monitoring the equipment parameters and the operational assignment of maintenance tasks;-ability to get all the necessary data for repair or replacement without the use of specialized software. ConclusionsThe development of the real estate management market requires to applicate modern methods and develop of new ones. In the framework of the present concept, it is possible to significantly improve operating organizations efficiency and quality of works.
