This research presents a methodology for classifying construction objects with critical defects. The presented work is part of a larger research effort dedicated to a comprehensive systemic approach to solving the problem of restoring various types of housing and social infrastructure objects damaged by different types of events. The paper discusses an algorithm for classifying construction objects with critical defects, introduces the concept of "degree of defect criticality", proposes a hypothesis about quantitative values of defect criticality degree intervals, and describes the classification algorithm. The presented examples demonstrate a holistic systemic approach to solving the scientific problem of restoring damaged objects affected by various types of events such as fires, explosions, impacts, and floods. Research methods employed include synthesis and scientific analysis, data collection, statistical analysis, as well as destructive and non-destructive testing methods at different stages of the study. Conclusions and tasks for further research are formulated.

When conducting quality control, it is necessary to consider the quality of both each individual element of the facade and the quality of the hinged facade as a system. When structuring the review of tools for instrumental quality control of curtain facade systems, their application should be considered according to controlled parameters, which can be divided into two groups. The quality control group of facade system elements combines methods and tools used in quality control of building materials and does not require the contractor to know about the principles of the hinged facade system. The quality control group of the device (assembly) of the hinged facade consists of operations to determine the quality of the operability of the hinged facade system. This group is entirely based on the idea of the work of the hinged facade as a single system. Based on the results of systematization and generalization of data, it was concluded that the current regulatory documentation regulates the use of instrumental control tools, leaving aside the issues of organization that come to the fore when quality control of the hinged facade of a construction object as a whole, when there is a task of choosing and using several tools of instrumental control at the same time. It is these questions that should be the subject of further research.

Keywords: systems of hinged facades, quality control organizations, a systematic approach in the organization, instrumental control, elements of the facade system, the device of the hinged facade, methods and means of control

The purpose of this work is to develop a list of possible categories of the need for major repairs and appropriate criteria for evaluating structural elements and in-house engineering systems. In the process of working on this study, methods of statistical data collection and expert evaluation were applied. As a result of this study, a table of the Category of the need for major repairs of apartment buildings, Criteria for assessing the need for major repairs of apartment buildings, was also presented by the algorithm of actions of a specialist in determining the need for major repairs of apartment buildings. This work is an effective and relevant method for determining the need for major repairs of apartment buildings in comparison with VSN 53-86(p) "Rules for assessing the physical wear of residential buildings".

The used mechanisms of management of the construction complex do not provide the desired result in the field of technical equipment of construction. Management of this line of activity is carried out without effective analysis and further planning. Therefore, the creation of integrated organizational structures, with specific tasks facing them, can provide, in the opinion of the authors, a solution to the existing problems identified in the article. It is proposed to create organizational structures of ""Centers of technical equipment of construction"" of two types, the main purpose of which is to increase the level of security of construction with the necessary machines and mechanisms.

Studies of building control issues are one of the most topical for industries and human life. The construction industry is one of those. The problem of safe and high-quality unique buildings is closely related to quality construction control.The article discusses the main stages of the documents regulating construction control in the implementation of unique objects, their systematization is given. The schemes of interaction of the main construction participants at the stage of construction and installation works with the obligatory involvement of experts in scientific and technical support of construction for the purpose of further study are presented.

The problem of increasing energy efficiency remains one of the most important for industries and human activity today. The construction industry is one of them.The problem of the construction of energy-efficient multi-storey residential buildings is closely related to the quality of construction control. The article discusses the main stages of the implementation of possible defects in the enclosing structures of a multi-storey residential building. The systematization of defects is given and the causes of their occurrence are presented. Solutions are also proposed to reduce the negative impact of poor-quality construction control of enclosing structures for the purpose of further study.

The article deals with the actual problematic elements of the organizational structure of enterprises in the construction of industrial buildings and structures. Using the method of optimizing the effectiveness of the existing organizational system, the necessity of introducing organizational and technological modules was revealed. An algorithm for optimizing the organizational structure of an enterprise during the construction of industrial buildings is proposed.

This article discusses the quality of final construction products and methods of its evaluation. Identified, proposed and justified the need for the introduction of a comprehensive quality indicator. On the basis of the analysis of the existing methods of quality control, it is proposed to create a Department in the service of the technical customer, which will deal with quality issues at all stages of the life cycle of the construction project.
