Abstract: The stakeholders of construction project have paid much more attention on the BIM technique which plays a core role during the process of construction information application.There are many successful instances of its application during the design and construction stage, which correspondingly compared with the researches and applications of the BIM technique in the field of economic feasibility analysis at the initial phase of the real estate construction. Four contents including the massing model developing, parameters transferring, key information abstracting and information handling are made deeply research based on the relation analysis between the economic assessment and Revit massing model. Furthermore, the actual case illustrated the detailed applying procedure of Revit massing model during the economic feasibility assessment of a real estate project.
