Lack of practical skills has become a prominent problem restricting the cultivation of civil engineering students. However, it is difficult to send large quantities of students to the construction site and design companies for a long time. Therefore, it is necessary to seek a digital and information-based simulation platform to replace the actual operation. This paper proposes a teaching platform based on BIM technology and its component library, and plans a knowledge unit mind map database, BIM component database, and BIM case database for students to learn and use. In addition, an intelligent evaluation mechanism of BIM model is introduced based on the software secondary development and optimization algorithm, so as to evaluate and guide the BIM model establishment by students in real time. The operation of the teaching platform is easy, the content is detailed, and it closely matches the actual engineering and needs of teaching, which can be used in teaching practice.
