BIM (Building Information Modeling) is building information modeling. BIM in construction industry for management, technical and application aspects of exploration has been unfolding. The nature of BIM is to realize the information full interoperability between the various professional of construction industry and improve building information reuse rate, which can reduce construction costs and improve production efficiency purposes. We combine practical projects on the concept and implementation of BIM to do a preliminary study and practice, and from the institute's work content and angle, conducted a preliminary exploration of 3D collaborative design workflow.In three-dimensional design mode, within the inter-professional and professional collaborative working methods are summarized.
