With the increasing adoption of BIM in building operation and maintenance, generating as-built Building Information Models (BIMs) for existing buildings becomes a growing demand. Converting laser-scanned point clouds into as-built BIMs (i.e., “Scan-to-BIM”) in the indoor scenes holds significant potential for the industry demand. This paper reviews the current state of indoor Scan-to-BIM research through a survey of 109 publications from the past decade. In the bibliometric analysis, the research status and relevant hot topics are identified. In the technical analysis, the implementation path, related methods for key steps, and modeling results of indoor Scan-to-BIM are statistically analyzed. Based on these findings, recommendations concerning development foundations, directions, and contents are proposed to foster the advancement of indoor Scan-to-BIM workflows.
