With the vigorous development of the construction engineering industry, in order to effectively improve the management level of construction engineering design, in recent years, Building Information Modeling (BIM) has been introduced into the field of architectural design and has been gradually promoted. Combined with the case of modular housing design, combing the integrated technical route of design collaboration under the BIM platform, and summarizing the efficient collaboration mode and work characteristics within and between majors. From the two aspects of software application and project management, explore the construction of BIM integrated multi-professional collaborative design process framework. Based on BIM, the computer-aided engineering design and planning platform has been greatly improved, up to 7.6%.
