Email: bazilashim@gmail.com ABSTRACT Asset documentation is a detailed record or inventory of the properties located within a room or a building. It is important to record the assets in case of property loss happen inside the premise especially when that premise caught fire, earthquake, robbery and others. The instrument used in this study is Faro Laser Scanner Photon 120/20. The object of the study is the computer room of Photogrammetry Lab, Faculty of Geoinformation and Real Estate. The final output of this study is the 3D model of the assets available inside the building. Before 3D model can be formed, the scanned data which is in the form of point cloud generated from the laser scanner have to be registered and georeferenced in order to combine the scans. The combine scans is the representation of the whole area of work surveyed from every scan points. These processes use Faro Scene, software that comes together with the laser scanner. By introducing this method, large scale asset documentation such as for factories and schools would be very beneficial rather than conventional method. The next process is to model the point cloud using AutoCAD 2011. Every item available on the room such as desks, chairs, cubicles, computers, whiteboard, projectors and cupboard are modeled and each of these items was inserted with attributes so that we can know the information of each items.

This application includes asset management, environmental modeling, reverse engineering, city planning, cultural heritage, and also piping (Aminuddin, 2010). 3D modeling is also a new way for data presentation as a final product of measuring and surveying technique. The 3D model can also be turned into a digital asset by associating it with critical information related to the physical asset and storing the 3D model and the associations in a database for retrieval and management of the digital asset. Laser scanning technology and digital close-range photogrammetry are two types of technology that can produce 3D model. The main difference between these two technologies is that the equipment that is used and the work procedure. Close range photogrammetry is a visual method where the camera orientations need to be solved first before capturing an image (Ordóñez et al., 2010). Meanwhile, like most of surveying devices, TLS need to be calibrated periodically (Santala and Joala, 2010).
