Building Information Modelling (BIM) as an UAV Information Processor for Generating an ‘As Built Drawing’

The heritage building is a valuable asset to humans and countries due to the grandeur symbolization and the dignity representation of a country. However, the dramatic changes on the historical building physical feature has been documented poorly. Subsequently, the depletion of the building information has making the maintenance works intricate. On site surveying might difficult due to the safety issue that putting manpower into risky circumstances. Advance technology may allow many to obtain information using aid of remote sensing, photogrammetry, geographic information system (GIS) and 3D laser scanning. The projection of the As Built Drawing might possible without utilisation of BIM as an analyser for the raw information congregated. Thus, the objective of this research is to develop an ‘As Built Drawing’ for heritage building using Building Information Modelling (BIM) as an information processor. The methodology involved the Unmanned Aerial Vehicle (UAV) application and Terrestrial Laser Scanner, photogrammetry image then been analysed using BIM. The identification of design properties of heritage building was obtained which consisted of architectural properties and structural properties. Therefore, the development of ‘As Built Drawing’ will be produced completely using BIM and in the other hand solving the problem on facilities management on the historical building.
