The introduction of information modeling technologies (TIM) into construction practice is irreversible all over the world. The effectiveness of the use of TIM has been proven at all stages of the life cycle of capital construction facilities: at the pre-design phase, at the stages of design, construction, operation, repair, reconstruction, de-installation and disposal. A variety of software for digitalization of construction allows you to choose the optimal product for a specific type of task. Until recently, most of the Russian information modeling technology market belonged to software products of foreign IT companies. Due to the changed conditions, there is a forced transition to domestic TIM systems. The challenges that arise in this case require joint actions by government agencies, software developers in the field of TIM, construction companies and educational organizations.

Reinforced concrete is the most common material in construction, this is due to its high performance and consumer characteristics. Despite a number of its positive characteristics, concrete has a negative property, its hygroscopicity. In the structure of concrete is a large number of micropores, cracks and capillaries, which contribute to the spread of moisture throughout the structure. This leads to the destruction of concrete, corrosion of reinforcement. Waterproofing is an important aspect of building construction and maintenance. It helps prevent moisture damage that leads to costly repairs and structural failure over time.

The article is devoted to the issue of making organizational and technological decisions when the stock of information for alternatives to choosing the required tasks is either very small, or they are changing drastically. Since it is not easy to make an organizational and technological business decision due to the fact that it is not clear what the result will be, it is proposed to use game theory in conditions of uncertainty. What kind of decision will be made and which of the available strategies the designer will adopt depends on what economic effect will be obtained as a result of the implementation of the organizational and technological solution being developed. Game theory is a special class of mathematical models for decision-making under specific conditions. By choosing solutions in the wake of uncertainty, game theory formalizes possible knowledge about the course of action of the participants in the game in certain conflict situations and allows you to mathematically substantiate knowledge about a rational course of action in certain conditions. When constructing construction projects in environmentally unfavorable conditions, the risk matrix is compared and the best option for the development of a construction project is determined.

" The article discusses organizational and technological solutions for the installation of hinged ventilated facades, which are aimed at: ensuring the efficiency of work; increasing labor safety and productivity, reducing the cost of installation work, eliminating wasteful consumption of all types of resources used, using progressive methods of organizing work; use of modern means of mechaniza-tion and automation. Organizational and technological solutions in the design of ventilated curtain walls were optimized in three stages. The main problem identified in this article is that in modern construction, with a wide variety of structures available, facade systems are selected without appropriate organizational, technologi-cal, and economic justification, mainly relying on the experience of previous construction projects. Therefore, the problem of lacking reliable tools for determining the effectiveness of various organi-zational and technological solutions for facade work production at the planning stage of the object's life cycle can be formulated."

This article discusses the problem of determining the parameters of the underground structure during large-block construction. The construction of buildings from large modules is a method of building construction, which is based on the use of ready-to-assemble modules of large sizes. This construction method allows you to significantly speed up the process of building construction, reduce construction costs, and ensure a high level of quality and functionality of structures, primarily due to the fact that these structural blocks are built in factory conditions. They can be made of various materials such as concrete, steel or composite materials. These modules can include not only walls and partitions, but also floors, ceilings, electrical wiring, plumbing and other elements, which reduces the assembly time on site.
