Geotechnical monitoring of the hospital Chernigov

Summary. Geotechnical monitoring is a system of observation, collection and data analysis on the condition of soils, basements and structural elements of facilities. It is a key tool for safety assurance and control during the reconstruction of structures. This is extremely important while old buildings reconstruction, where unexpected reactions to changes in loads are possible. The monitoring of emergency facilities is especially important, where even minor changes can lead to serious consequences. Geotechnical monitoring of the Chernihiv`s hospital was conducted. The building was put into operation in 1982. Since 1984, the building began to deform. There were opening of temperature joints with displacement of transverse walls, separation of the longitudinal wall from the transverse ones, minor deformation cracks in other blocks were detected. In the early 1990s, the works for strengthening of the structures was carried out, but they were not fully completed. In 2016, a major repair of the roofing and the drainage system from the building were carried out. The deformation of the building did not stop. In 2018, the SE NIIBK conducted a study and, based on the recommendations of «Eurotechindustry» LLC, a reinforcement of the stairwell was developed. However, in 2022, during active hostilities in the Chernihiv city, the hospital was severely damaged. There were direct hits and the collapse of structure`s elements. The meticulous inspection of the facility in order to establish the residual resource and reliability of the whole structures becomes necessary. An inspection of the hospital building as well as geotechnical monitoring, particularly engineering and geodetic observations, and verification calculations of the basement were performed.
