Abstract: By producing 3D, 4D and even nD parametric models, the technique of building information modeling( BIM ) offers a platform for all participants of a project to enhance communication and cooperation in entire life cycleof a project to realize greater visualization effect, shorter schedules, improved construction methods and better costcontrol. This article aims to describe the BIM modeling process by taking a realistic construction project＇s BIM 3D and4D modeling for example, it is expected to provide a reference for the popularization of BIM application in China.
