Coordination among different project disciplines is a critical stage in a prefabricated projects and it has obvious influence in the total cost and efficiency. Prefabrication is a construction practice whose basic unit is the component which is also regarded as the basic element of BIM. Taking advantage of BIM in building life-cycle management and coalescing the idea of omniclass and model view definition, this research suggests an approach to improve information integrated management, including information classification and information delivery, in prefabrication using ontological technologies. The development process contains three stages: 1) work scope definition, which is to set a research topic and limit work boundary; 2) knowledge flow map creation, which is to describe important work processes and data or knowledge exchange among the involved stakeholders; and 3) ontology development, which is to generate data sharing ontology and domain ontology generation, and define alignment rules and constraint rules based on the knowledge flow map. Through the proposed ontology-based approach, the stakeholders are able to create information which represents their views of the projects and make appropriate use of the knowledge iteration in the prefabricated projects. Finally, a case study on cost estimation and optimization in prefabricated project is undertaken for validation of this method.
