Ground laser scanning as a tool for creating buildings-and-structures’ information modeling (BIM)

Abstract

The role and place of ground laser scanning in the process of creating information models of the construction object at different stages of its life cycle are discussed. It is noted that ground laser scanning is the main way of creating point clouds of buildings and structures. The composition of information models characterizing the construction object at different stages of its life cycle is considered. It is indicated that ground-based laser scanning is the best solution for the information modeling problems in constructing an object, in particular, for its geodetic control. The authors provide examples of using ground laser scanning data for geodetic control at different stages of construction. In conclusion, the relevant problems of three- dimensional building-models, which can be solved using the technology of ground laser scanning, are indicated. It also noted what advantages ground-based laser scanning has as a tool for information modeling construction projects.
