First step in the direction of a „smart project”—the surveying of the extant state of a building in the BIM standard

Abstract

Thanks to the numerous benefits gained from the implementation of the latest information technologies in architecture and construction, BIM is unavoidably becoming the standard of modern design. BIM Technology also applies to the stage of surveying a building.

The sequence of work when surveying a building in the BIM standard on the basis of laser scanning is as follows: The first task to be performed is tachymetric measurement. Afterwards, as a result of laser scanning, we obtain so-called point clouds, from which so-called orthophotoplans are generated. Based on these plans, a virtual model of a building is generated. After applying dimensions and annotation from the 3D (4D+5D) model, we can generate floor plans, cross-sections and eleva­tions, as well as various types of schedules.
