The analysis of the existing management systems for investment and construction projects showed that the organizational and technological models used for the development of the calendar plans are static and do not reflect changes in the course of real-time work that does not allow synchronizing the terms of production and supply of resources and leads to significant losses in use of manpower and construction machinery. The adaptability of organizational and technological models in the developed intellectual building management system is ensured through the use of special algorithms and models for disaggregating planned and aggregating actual information on work, calculating deviations of actual characteristics from planned values, developing and making decisions to bring the model to the organizational and technological normality in real time mode

The article deals with the problems existing in our country that arise in the construction of buildings and structures using new materials and engineering technologies. As shown by the analysis, one of the most significant problems in this area is the violation of production technologies using new materials. To overcome this situation, it is proposed to set the technological normal at the design stage by developing technological maps that take into account the composition and sequence of operations taking into account the properties of energy-efficient materials in detail. In Donskoy State Technical University (DGTU) is developing an intelligent management system that provides organizational and technological and information integration of the stages of design and production through the creation of a single database of technological maps, volumes of work and resources
