The global global trend in the development of modern computer technologies contributes to the introduction of BIM technologies in the design, construction and operation, working with a single model of a building or structure throughout the entire life cycle. The challenges that arise in the design and construction process stimulate the development of digital technologies, and those, in turn, require continuous study and improvement of knowledge in these areas. To maximize the effectiveness of projects and the implementation of architectural thought by means of information technology, new requirements for the work of architects are emerging. In this direction, it is necessary to train architects and designers of a new generation and to retrain long-time practitioners. In this paper, we have considered the advantages and disadvantages of the transition of the full cycle of architectural and construction design in IT modeling. We studied the issue of rapid identification of shortcomings and instability of the design of the projected building due to the integration of programs: ArchiCAD, SAPPHIRE, LIRA-CAD.
