In recent years, engineering projects have gradually become difficult and complex, and the traditional engineering technology is facing arduous challenges. In order to optimize, automate and modernize the traditional processes of the construction industry, the Building Information Model (BIM) has emerged, which has changed the prospects of current construction projects. BIM is a huge digital platform, which integrates construction engineering data and information, can be used as the core hub in the whole life cycle of construction engineering, and provides visual, digital and convenient services for the overall management of construction projects. BIM technology has effectively improved the quality and efficiency in the whole life cycle management of construction engineering. On the large platform of BIM, the processing, conversion and handover of engineering data become easy and convenient, and the related problems of various majors have found a solution. Through the coordinated design of BIM technology, improve the work efficiency of the project team; use BIM technology to express the designer's design concept more intuitively, at the same time, it can avoid errors in two-dimensional drawings and improve the efficiency of design. BIM technology can also well display the construction progress and provide data to support the establishment of a more reasonable construction process. To sum up, the application of BIM technology in design greatly improves the design technology, construction efficiency and project quality. Through the establishment of the civil engineering model of RongChang District Education and training Center, this paper focuses on the in-depth study of the application of the model, so as to have a certain understanding of the functions and applications, advantages and problems of BIM, and provide some references for the specific application of BIM technology in engineering.
