Abstract: Although the BIM technology has been used in China widely, the value that BIM technology produces is not fully reflected, because there is no uniform industry standard. This article mainly discusses BIM process standard from the perspective of software solutions, and uses IDM method to analyze the design process. The paper draws the process map of BIM -based collaborative design, uses the corresponding form to list the contents of activities and partial exchange requirements in the process map, and makes some IFC -based data description of partial contents of MVD. It cannot only help the designers to clarify the professional task and improve design efficiency, but also provide a reference for the development of the industrial BIM standard.
