Technologies of building deformation monitoring in Latvia

Determining the deformations of a building is a very important process in the construction and operation of a construction site. The main causes of deformation of structures and their foundations are sedimentation of foundation structures, weak load-bearing soil, crushed sand layers, wear and degradation of building foundations, uneven or excessive loading of foundations, poor condition of pile foundations, regular ambient vibrations, support of ambient temperature, various loads caused by wind, snow and other conditions, uncompact soil. The quality of building materials, binders, and aggregates can also be mentioned as the causes of the deformations of buildings and foundations. The paper analyzes the available information and regulatory enactments related to the monitoring of building deformations, evaluates the provision of building deformation in Latvia, describes the types of building deformations and their causes, building deformation monitoring technologies, as well as building monitoring methods, and summarizes the results. The aim of the study is to investigate and evaluate the deformation monitoring system of buildings. The results of the research reflect the procedures and technologies of deformation monitoring of buildings, the possibilities of using high-precision deformation sensors, substantiating the need to create an automated height, load, and other deformation-causing properties, and measurement control system. The work provides a specific assessment of the building deformation monitoring object in Strēlnieku Street in Riga.
