Especially, the conceptual or approximate estimation is important to assess the project feasibility and budget planning. However, due to limited information and time, there is an issue concerning low-level reliability of the approximate estimating results. The main objective of this research is to provide 3D BIM collaborative approximate estimating model using detailed as-built information of the previous similar projects. In order to achieve the objective, this research builds standardized floor plan database. Space factors and variable factors are extracted from 3D modeling to a
