The article is devoted to the topic of a comprehensive survey of engineering structures that are in operation. It has been established that with the help of visual assessment it is impossible to give a reliable assessment of the current state of the structure. Modern geodetic instruments significantly expand the capabilities of engineers for technical control, therefore, in the article, special attention is paid to this type of work.
The survey is carried out on the example of a building that was erected according to a block space-planning scheme. The planning scheme is based on separate blocks of different heights and sizes. This is the reason for considering the sequence of performing the survey on this type of object. In the course of the survey, work was carried out on a visual assessment of building structures and their joints between each other, deviations from design solutions and design standards were established, an analysis of the spatial position of structures and deviations from the project and standard indicators was carried out. To clarify the structures of the foundations and establish their compliance with the design data, pits were made in places regulated by the terms of reference. The pits were carried out in a combined way to the depth of laying the foundations. According to the results of laser scanning, the spatial position of the structures on the executive diagrams was recorded. Scanning was carried out in three blocks. To assess deviations from the boundary normative indicators, an analysis of the results of scanning the planned position of the building's supporting structures was performed. Based on the results of the tacheometric survey, design solutions were established that do not meet the requirements of the current regulatory documents in terms of proper fastening of structures to each other and disregard for the conditions for ensuring the rigidity of structures, which can lead to a decrease in the overall rigidity of the frame and cause excessive deformations. Deviations were also established that are a multiple of the limiting parameters normalized by the regulations, reduce the overall stability and rigidity of the building frame, contribute to the appearance of additional, unforeseen design loads on structures, increase the risk of structural failure and negatively affect the overall level of reliability.
Based on the results of the research, it was concluded that the use of modern electronic geodetic instruments can significantly expand the capabilities of engineers for technical control.
