Abstract: With the rapid development of the construction industry, prefabricated buildings and Building Information Modeling (BIM) technology have gradually become important development directions in the field of civil engineering. The article explores the reform practice of civil engineering graduation design based on prefabricated building and BIM technology, analyzes the advantages of these two technologies in improving design efficiency, optimizing construction processes, and promoting sustainable development, and proposes specific reform measures. Through reform practice, students'comprehensive abilities and graduation design quality can be effectively improved, providing useful leference for the future development of the civil engineering industry.

Key words: Prefabricated building, BIM technology, Civil engineering, Graduation project, Reform practice, Innovative thinking
