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.

An important condition for the high-quality development of the construction industry is the further increase in energy efficiency and environmental friendliness of design solutions in the field of roof enclosing structures. Therefore, solving the problem of correctly choosing the most effective roof instalation to increase the life cycle of the entire building becomes more relevant. The widespread use of a wide variety of both traditional and more durable and reliable roofing coverings in modern construction practice makes it difficult to choose the most effective option. The article develops a methodology for choosing an effective roof instalation option based on the use of economic and mathematical tools, based on the analysis of organizational and technological calculations and technical and economic comparison of various options

This article analyzes trends and examples of the use of digital technology in order to increase the efficiency and improve the quality of construction projects. BIM technologies already at the design stage make it possible to provide as much as possible all the signs that affect the construction object at the beginning of construction and its further operation. The number of these signs increases, due to the fact that the complexity of the construction process of construction objects increases, as the scale of construction increases, the volume of construction products and building materials increases. In this connection, the requirements for the general designer, contractor, customer, etc. are increasing. At the same time, the customer expects to find, in addition to the project, a solution to reduce costs and increase the functionality of the construction object with the highest parameters. The need for high-performance special technologies and methods of organizing the management of construction works is becoming more acute. BIM technologies are the physical and functional characteristics of a construction object presented in digital form. Digital technologies are an integrated special resource of competencies in order to obtain information about a construction object. It provides the basis for the possibility to accept special decisions of a construction object from construction to the moment of its demolition. This model provides an opportunity to delegate a virtual digital model from the creators of the project to the subcontractor, general contractor, owner, as well as the manager of the construction object. The technical tasks of using information modeling technologies are the starting point for planning an investment project both from the customer's position, since they define the scope of using a BIM model at all phases of the operation of a construction object according to the criteria for evaluating information, and from the position of the contractor, since it acts as the basis for generating a plan when a BIM project will be implemented. The list of characteristic technical tasks of BIM modeling application at different stages of the construction object life cycle is determined. The BIM project algorithm is proposed.

One of the tasks of the state is to create decent living conditions for the population, including providing people with high-quality and comfortable housing. However, over time, housing wears out, becomes outdated, and becomes unsuitable for use. In order to slow down and prevent rapid deterioration of capital construction projects, capital repair measures are being implemented. They are aimed at restoring and replacing structural elements of residential buildings that have fallen into disrepair. Overhaul of housing is a complex of organizational, technological and economic measures aimed at reducing and eliminating the physical deterioration of buildings. Thus, the creation of decent living conditions for the population and the safety of the housing stock, as well as increasing its energy efficiency, depend on the effectiveness of the organization of the capital repair system and its organizational and technological support.

This article analyzes the assessment of the signs leading to the possible destruction of the studied building structure. To determine the degree of influence of signs (or groups) on the level of structural failure in their direct diagnosis, it is possible to use a mathematical basis, in particular, the Bayesian approach. The essence of the implementation is to compare the probability of failure for each structure under study. The result of the work is to identify and describe not only the features of the relationship between each feature affecting the destruction of the structure and the calculated probability of destruction, but also their degree of influence on increasing or decreasing the probability of an accident. According to the estimates of the mathematical definition of the signs affecting the destruction of the building structure, it is possible to more objectively assess the effectiveness of the method used to check the condition of the building structure.

By conducting a construction and technical expertise on the inspection of building structures and identifying several signs that can lead to their destruction, it is possible to identify a defect in which the destruction and accident of the structure under study is most likely to occur. It is proposed to use a Bayesian approach to evaluating the effectiveness of methods for determining defects affecting structural failure. The use of knowledge on the inspection and testing of building structures of buildings and structures is to determine the degree of relationship between the possible destruction of a building structure and its inspection, based on methods developed in the theory of reliability of technical systems. Based on the results of mathematical determination of the degree of malfunction, it is possible to more objectively assess the effectiveness of the method used to check the condition of the building structure.

This article analyzes the assessment of the signs leading to the possible destruction of the investigated building structure. Using the mathematical basis for diagnosing the destruction of a building structure, it is possible to determine how the signs that affect the destruction of the structure or their groups affect the determination of the degree of destruction. Applying the Bayesian approach to determining the degree of malfunction of a building structure and its destruction, a comparison of the probability of destruction of each investigated building structure is given. It was found out how the calculated probability of each structural failure was affected by the presence of each feature and what contribution to the increase or decrease in the probability of an accident was made by the analyzed feature affecting the destruction of the structure. It is proposed to use artificial, model destruction of building structures to determine the influence of various factors on determining the degree of destruction, so to speak, in its pure form and in various variants. In addition, you can get test cases to test the effectiveness of various diagnostic methods and find out a number of theoretical questions. Considering this, and the other goals listed above, models were built. An assessment of the influence of a feature that affects the probability of destruction of a building structure in one of many ways is shown. According to the proposed methods, the values of the sign affecting the destruction for the structure are determined. The probability of destruction is determined.
