Abstract:A collaborative design based on building information model (BIM) technology is the orientation of architecture, engineering and construction industry. This paper focuses on the information exchange problems in collaborative design, such as timeliness, completeness and accuracy. Based on the advantages of two kinds of collaborative design methods, such as document linkage and working set of building information model (BIM) technology, and the case study of modular housing design, an analysis is made of the design collaboration technology roadmap, at last, an efficient collaborative model and working characteristics within profession and inter-profession are obtained. From the prospects of software applications and project management, the process framework of BIM multidisciplinary collaborative design is explored, so as to provide a useful method for multi-disciplinary and efficient coordination in the architectural design stage.
