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.

The article raises issues of repair and construction work on the installation of underground utility pipeline networks in urban environments. The sphere of housing and communal services today is characterized by the presence of high wear and tear of communal pipeline networks: sewer systems, water supply systems, energy systems, etc., which requires urgent measures to solve this problem as part of the implementation of urban reconstruction projects.

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. A concept for the development of a new scientific direction "High-strength composite materials based on lime (hydraulic and hydrate), gypsum (gypsum and anhydrite) and magnesia binders for the repair and restoration of cultural heritage sites" has been developed.

The relevance of forensic construction and technical expertise in the Russian Federation increases with the increase in the level of urbanization and at the same time the community of forensic construction experts with deep knowledge in the construction field obtained as a result of professional education is growing rapidly. The article raises the issues of lagging the level of preparedness of construction experts in procedural matters, in the skills of mastering the art of polemics, in the ability to flawlessly design the results of the examination in the form of an expert opinion. The authors of the article, based on the study of the practice of conducting judicial construction and technical examinations, analyzed the organizational and legal problems arising from the expert in connection with the violation of the principle of unity of form and content during the examination, underestimating the importance of putting evidence in a strict procedural form.

A feature of modern construction is the large-scale reconstruction of blocks in the center of large cities. In recent decades, investors have increasingly sought to increase the number of storeys of buildings. However, the construction of high-rise buildings (above 75 m) in the conditions of the current development of the metropolis has a number of problems that can negate all the benefits of placing a real estate object in the central districts of the city. The greatest problems are identified already at the design stage of the foundations of high-rise buildings. The article discusses 5 key problems that have the maximum impact on the increase in the cost of construction of high-rise buildings.

The article considers the assessment of the construction of social facilities in the development of territories of integrated development on the example of Rostov-on-Don. As part of this, the analysis of the territorial needs of the city of Rostov-on-Don in the construction of social institutions, spatial analysis of the placement of territories of complex development was carried out. A project for the construction of a preschool institution using green technologies has been developed and the effect of the results of the construction of the projected preschool institution has been calculated.

This article discusses the relationship of all stages of the life cycle of buildings on the basis of information-analytical system IAS HCS. The full life-cycle cost of a 1,000-seat school was calculated. Using the IAS HCS program, we made calculations of the costs of repair work on three models: without taking into account any repair work, taking into account the repair of the main structural elements and taking into account the repair of all elements, based on the standard operating time. Real estate life cycle cost analysis can be performed for both new and existing buildings of any type (residential and public). Evaluation of the total costs of the full life cycle of the object can be applied by both the developer and the owner of the building to further improve the management system of the property.

This article discusses the possibilities of BIM technologies for predicting, responding to and eliminating the consequences of natural and man-made emergencies. BIM systems make it possible to simulate various scenarios in the event of an emergency and choose the most effective and safe solutions to minimize human and material losses, and improve the level of managerial decision-making during evacuation. Modern technical means used in conjunction with BIM technologies make it possible to acquire knowledge and practical skills as part of the training of rescuers and other specialized services.

Urbanization as a process of urban growth has only recently become controlled by the authorities. Spontaneous or accidental occurrence of any elements of the urban environment with low quality indicators is the most common phenomenon in the last century. Nevertheless, the decisions taken "from above" to create a high-quality urban environment are designed for large-scale transformations for decades to come and cannot meet the needs of citizens in solving pressing problems here and now. The article discusses modern tools and methods for the development of the area by urban residents, the principles of tactical urbanism are considered.
