Research on BIM-based Construction Domain Text Information Management

Abstract

Construction project produces a large amount of unstructured information throughout the whole lifecycle, most of them is text information. Building information modeling (BIM) can support lifecycle information management of construction project, so BIM-based construction domain text information integration management can improve the efficiency and quality of project management to a large extent. The concept of BIM and its implementation platform, as well as the data exchange standard, i.e. industry foundation class (IFC), are introduced firstly. Then this paper puts forward a systematic unstructured construction domain text information management system framework, and the implementation of BIM-based text information integration methodology: the unstructured text information is transformed to structured information by means of text mining to facilitate information retrieval and ranking; then the text information is classified according to the IFC standard, and is associated with entities in BIM to realize the integration of text information and BIM. Finally, this paper takes contract document as an example for verification. The proposed method can improve text information management ability and efficiency of construction domain.
