Department of Construction Engineering and Management: Faculty Publications

The difficulty of timely retrieval of useful information from heterogeneous data sources is a major cause of low productivity in the construction industry. The goal of this research is to provide a new methodology to handle the data-heterogeneity problems encountered in a construction project. This research proposes a tree-structured product model, which binds design knowledge, cost data and schedule data together, as a feasible solution for the data integration problem in construction projects. The methodology uses the knowledge representation of construction projects based on an ontology. Metadata are used to describe the conceptual structure of the project knowledge. The concept …
