This study analyses the usefulness of 3D scanners in recording pipe locations within newly constructed buildings. With a better understanding of the pipe layout within a building, better plumbing system management should be possible. During the building construction process in the past, pipes would offset sideways or factor in other design changes. Other construction operations, such as ceiling installation, wall partitioning, and shaft follow-up, complicated the building pipe data when attempting to locate pipes or determine their future usages. The 3D scanner used in this study recorded the finished pipe layout during the building construction process. Pipe information, which was made of point clouds, accurately displayed the as-built location of the pipes on the construction site. Point clouds were checked against the as-built shop drawings to correctly control the pipes' real status on site for the building management and maintenance department. As a result, the maintenance department could more easily obtain the pipes' location and determine the functions and attributes of the pipes before maintenance was conducted
