The use of information modeling at all stages of the life cycle of a construction object requires a revision of existing approaches to organizing the work of specialists, a more thorough study of the processes of information exchange, the search for new more effective ways of managing information and organizing the use of models. By the period of operation of the constructed object, a significant amount of various data and documents is generated, and during the operation of the building or structure there is a need to collect and analyze significant amounts of information. Damage detection and prediction of structural behavior, search for the current location of a building element can take a lot of time, and a systematic approach to information flow management will ensure an increase in the efficiency of operation services by reducing costs during unscheduled repairs and increasing the life of buildings. This article discusses a model of the integration process of data received or transmitted by Radio Frequency Identification technology tags and data stored and used in an information model. Tags can be placed on critical structures, in complex nodes or on cracks to monitor their disclosure. The approaches to managing information flows depending on the tasks solved at the operational stage, taking into account the preventive maintenance of building elements, are given.
