This paper presents that acquiring 3D-shape through reverse-engineering of the old facilities using 3D-Scanning method and suggesting means of enhancing old facilities management and replacement time for application of BIM. In the experiment, we use the equipment which is multi-laser 3D-Scanning to calculate the distance from objective to it. And then, we could get 3D-shape data for application of BIM which model more information of building. This BIM is taken advantage of prevention or prediction of risk by current facilities
