BIMs constructed from a CAD model do not generally capture details of a facility as it was actually built. Laser scanners can be used to capture dense 3D measurements of a facility's as-built condition Keywords: and the resulting point cloud can be manually processed to create an as-built BIM — a time-consuming, Building information models subjective, and error-prone process that could benefit significantly from automation. This article surveys Building reconstruction techniques developed in civil engineering and computer science that can be utilized to automate the process Laser scanners of creating as-built BIMs.
