Abstract
Abstract. 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.
Highlights
With the development of technological progress, as well as digital technologies, it is relevant to discover the question of the possible application of this direction in matters of geodetic support of the construction process
It is important to mention that this technology brings the greatest efficiency when it comes to an integrated approach while working with a construction object, when the information model covers all areas of the engineering object service
The results obtained during the project installation demonstrated the effectiveness of the use of building information model (BIM) technologies for solving engineering problems in the geodetic support of the construction industry
Summary
With the development of technological progress, as well as digital technologies, it is relevant to discover the question of the possible application of this direction in matters of geodetic support of the construction process. It is important to mention that this technology brings the greatest efficiency when it comes to an integrated approach while working with a construction object, when the information model covers all areas of the engineering object service In this case, the more accurately the BIM model of an engineering structure is built at the initial stage, the more likely in future it will work without failures and errors in real time. BIM-modeling allows presenting the work in a new, high-quality informational and visual form, and creating a model that will be as close to reality as possible It will help avoid design errors and structural deformations during the design and further building operation. The purpose of the study is to develop a methodology for monitoring deformation processes of engineering objects and for assessing the quality of construction operations using a set of BIM-technology tools when digitizing geodetic measurements
