The traditional talent training mode of civil engineering has many shortcomings, such as low participation of enterprises, course content lagging behind the development of industry technology, loose combination of theory and practice teaching, and backward management methods. Through in-depth investigation and research, the research group puts forward the new talent training mode of "3 + 0.5 + 0.5", which is the process of theoretical learning, practical growth and theoretical carding, to build a long-term mechanism of school-enterprise linkage talent training. Integrating modern engineering intelligent manufacturing technology, the professional curriculum system is reconstructed. Relying on the platform of national BIM skills competition, project driven teaching is implemented to cultivate engineering intelligent manufacturing ability. Using information technology to reform traditional teaching and management methods, boundless teaching and practice management are implemented and a quantitative evaluation system of practical teaching quality is constructed. The comprehensive reform of civil engineering specialty has been highly recognized by the industry and enterprises, and the quality of personnel training and employment has been steadily improved.
