Research on the Building Information Model of the stone building for heritages conservation With the outer south gate of the Ta Keo Temple as an example

This article mainly discussed the principle and method to create the Building Information Model (BIM) for a stone architectural heritage. As a typical case for stone heritages, the BIM of the outer south gate in the Ta Keo Temple in Cambodia was built according to requirements on heritage protection and management. In the case, we studied three important problems about the stone BIM: the mode of the BIM, the sorts of the families and the contents of component attributes. By literature study, on-the-spot investigation, data analysis and repeating tests, we not only set a dynamic BIM for the gate, but also summarized primarily the basic techniques and scientific flow to build the BIM for a stone heritage.
