MONITORING THE DEFORMATION PROCESS OF ENGINEERING STRUCTURES USING BIM TECHNOLOGIES

This paper reports on the scientific approach to integrating the results of geodetic measurements into an integrated BIM system for geotechnical monitoring of building structures. The method is based on systematic monitoring of deformations with the determination of the influence of external factors, which makes it possible to process a significant amount of information obtained during the monitoring process and promptly process the information about the stress-strain state of the object in real-time. New technology for assessing the technical condition of high-rise buildings is proposed. The core of this technology is an estimation of defects and deformations of structures using BIM during the building construction and operation. Using the mathematical tools of BIM technology in geotechnical monitoring of engineering structures makes it poss ible to create a quantitative information model. The model comprises the results of geodetic measurements, measurements of climate loads, and measurements of geological deformations. As a result, a quantitative assessment of defects and damage during the construction and operation of high-rise buildings becomes possible. BIM allows determining the risks of critical states occurrence of building structures, assessing the probability level of the ir occurrence, and predicting the degree of influence of these risks on the safe operation of the entire structure. Simultaneously, the BIM estimates the stress-strain state of a high-rise building based on the results of deformation monitoring. The considered approach is affordable to any measurements. The use of information technologies in the monitoring of engineering structures during construction and operation will make it possible to collect and accumulate significant statistical data related to the influence of specific external factors on the stress-strain state of the structure. Subsequent processing of this information will make it possible to identify and predict the dependence of defects and deformations of building structures on certain factors and cla rify their weight values.
