Building Information Modeling (BIM) is an innovative technology for managing and using construction information, and it has been widely used for construction decision-makings in recent years. Construction decision-makings have to consider both duration and cost perspectives for a project. However, existing relevant BIM-based studies seldom took into account the two perspectives simultaneously, thus making decision-makings inappropriate. Therefore, this study proposes a model to address the limitation and to facilitate evaluating both the duration and cost of construction projects and determining a construction plan which is most suitable for the needs of engineers and planners. The proposed model is based on BIM, computer simulation, and ontology: BIM provides quantity information, computer simulation estimates project duration, and ontology acts as a unit price analysis knowledge base for retrieving the unit prices of the work items in a construction plan and evaluating project cost. The results show that the proposed model can effectively assist decision-making in selecting construction plans, and generate necessary information for construction management and control.
