RESEARCH ON HBIM AND LEVEL OF INFORMATION FOR THE LIFE CYCLE OF TRADITIONAL CHINESE BUILT HERITAGE IN TAIWAN

Abstract. As a witness of history, built heritage has many values that is very important to human being. Therefore, how to conserve this valuable information becomes a common issue for cultural heritage conservation in the world. Many researches about conserving the information of within built heritages were done and more issues were raised. The difference between built heritage and new building is that built heritage is not from 0 but it is already exist. This difference cause a big different for modelling process of built heritage in BIM environment. For this reason, the information of the 3D model of built heritage is added to the model after the it was created. So, what information should be conserve and what information should be provided to which user is worth of discussion. This research aims to propose a data structure, which fulfils the requirement of user, and respect the standard of important international chart of conservation. The method is to define a basic data structure of built heritage components and evaluate it layer by layer. The result shows that HBIM for built heritage, by linking information, can store more important information and take the LoI of life cycle into consideration simultaneously. The prototypical schema of this study may possibly be an upper layer concept for later researches in both Western and Eastern built heritage.
