As-Built Point Cloud Review of a Ceiling Plumbing System

This research used a 3D scanner to retrieve the geometric information of finished pipe layout inside ceiling space and used the 3D point clouds to facilitate follow-up building management. The presence of as-built pipes enables the measurement of relative locations between various pipes, pipes and slabs, or pipes and walls. This allows the building contractor to determine if plumbing space should be increased with toleration according to the layout or possible maintenance of pipes and the passing route in the future.
