Experience in the use of ground-based laser scanning at inspecting engineering structures

Abstract

Using the implemented objects as an example, the advantages of using laser scanning at inspecting technically complex structures and strain monitoring are shown. The practice of using scanning while protecting a cultural heritage object, preparing the initial data for BIM modeling, for examining artificial structures and determining deformations of a road embankment is described. Examples of sharing software products for processing and interpreting laser scanning results are presented. The description of creating a survey justification for working on ground-based laser scanning is given. The advantages of introducing laser scanning technology into theenterprise’s activities are shown. Real examples show that the use of ground-based laser scanning enables restoring lost project documentation, determining the deformation of structural elements, monitoringthe current shape of the embankments, evaluating the volume of sedimentary rocks and solving other problems. It is noted that the use of laser scanning can significantly reduce the time required for field work, which is especially important when working at objects with a limited access mode.
