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 However, over time, housing wears out, becomes outdated, and becomes unsuitable for use.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.

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.

Repair and restoration binders and compositions based on them are needed primarily for the repair, restoration and restoration of cultural heritage sites both in the Russian Federation and abroad. They are subject to special requirements, so the conduct of related engineering and survey, research and development work is an important condition for the development of modern scientifically verified, practically tested and in demand in practice repair and restoration materials. One of the main conditions for the practical implementation of the proposed investment project is the presence of a mineral resource base in the region and the country. The resource potential of carbonate, halogen and clayey rocks is fully represented in the mountainous part of the Chechen Republic (CR). Based on the results of research and prospecting work on the territory of the Czech Republic, 6 forecast areas have been identified that are promising for the identification of deposits of carbonate, halogen and clay raw materials, mainly as lime, cement and multi-purpose. The work uses methods of analytical research and scientific generalizations, expert assessments, process modeling and system analysis. The classification of inorganic binders was performed, which for the first time included organic-inorganic binders and additives in repair and restoration binders and compositions. As a result of exploratory research, it was proposed to repair, restore and restore historical and cultural monuments using the ones developed at the Kh.I. Ibragimov RAS of modern technologies and materials for repair and restoration work. To assess and correct the scientific problem associated with the development of repair and restoration binders and repair and restoration compositions, a review of historical experience was made.
