The implementation of Building Information Modeling (BIM) technology in the development of a lifecycle cost-estimating tool is presented. The IFC (Industry Foundation Classes) model as an interoperable building information model is adopted as the central data repository to deliver the integrated information of building designs from CAD design systems into the lifecycle-costing database. The conceptions and relevant factors, which could affect the LCC estimation, are introduced. The problems of current LCC applications are identified as the lack of LCC data and the complexity of LCC exercises. The software application of IFC models and relevant auxiliary are depicted as a solution of the problem identified. The lifecycle costing tool is a part of the nD Modeling tool and as such is based on its integrated interface prototype toolkit and is able to holistically present an IFC model into a 3D virtual reality view, a tree-view and a list of element properties. The functions and some technical points are also detailed in the paper. Through the research, it demonstrates the potential and possibility of implementing BIM methods and techniques, particularly IFCs to enhance the computer applications in the processes of building construction and facility management.
