New engineering disciplines emphasize practicality, interdisciplinarity, and comprehensiveness. The graduation project is a crucial phase in undergraduate education for developing students" comprehensive abilities. However, there is a lack of a graduation project teaching model that fully meets the talent training goals of the new engineering discipline in Intelligent Construction. Based on the Outcome-Based Education (OBE) concept, this study explores innovations in the graduation project teaching model, including designing interdisciplinary topics for the graduation project, organizing a nonlinear learning process, and forming a comprehensive presentation of the graduation project results. Using the 2024 cohort of the Intelligent Construction program at Huazhong University of Science and Technology as an example, this study introduces these innovations and their outcomes. Over 90% of students expressed strong approval and positive feedback on this model. Through systematic training, students in the Intelligent Construction program not only master technical skills but also develop innovative thinking and innovation capabilities, thereby further advancing their overall professional development. The innovative model explored in this study provides valuable references for the graduation project and talent training efforts in other new engineering disciplines.
