In this work, based on an analysis of literary scientific and technical sources and completed field studies, the problem of degradation of reinforced concrete and metal structures of long-term operation is formulated and its relevance is noted. The authors analyzed a number of works on this issue. Examples of the use of modern methods and materials for strengthening reinforced concrete and stone structures with damage and defects to restore their load-bearing capacity are described. The paper presents the results of a visual review and instrumental study of reinforced concrete and metal load-bearing structures of the former “Modul” plant, built according to the II-03с and II-60с series, as well as external self-supporting expanded clay concrete wall panels, brick walls, staircases and partitions. General information about the building and its design is provided. The objectives of the study included establishing the actual technical condition of the building’s structures and the possibility of its subsequent reliable operation after repurposing. During the examination, non-destructive testing methods and laboratory tests of materials were used to obtain actual strength indicators, humidity, the degree of corrosion damage to materials, and geometric characteristics of structures for their identification. The main reasons that necessitated the research and development of recommendations for eliminating identified defects and damage, as well as shortcomings of long-term operation, have been identified. Data are provided on detected defects and damage that occurred over a long period of time. According to current standards, the general technical condition of the building has been established as satisfactory (category 2) and appropriate conclusions have been formulated regarding the need for repair work. Based on the results of field surveys, relevant calculations and conclusions, recommendations for the repair and elimination of identified defects and damage were developed.
