Against the backdrop of digital-intelligence technologies profoundly reshaping the construction industry and industry-education integration becoming a core direction for vocational education reform, the traditional curriculum system of the engineering cost major in higher vocational colleges faces the dual dilemma of “technical disconnection from the industry and teaching detachment from practice.” This paper takes the engineering cost major at Chongqing Energy Vocational College as the research subject, systematically analyzing the background and significance of curriculum system construction from the “dual-collaboration” perspective of industry-education integration and digital-intelligence integration. It clarifies four construction principles: “symbiotic integration of digital-intelligence and major, precise alignment with enterprise needs, integration of courses, positions, competitions, and certificates, and dynamic optimization.” Subsequently, it proposes three construction paths: a modular curriculum framework design of “digital-intelligence foundation–professional core–practical innovation–ideological and political integration,” collaborative development of curriculum resources by schools and enterprises, and an integrated assessment and evaluation system of “courses, positions, competitions, and certificates.” The study aims to provide practical references for cultivating compound technical and skilled talents in the engineering cost major of higher vocational colleges to meet the demands of the digital-intelligence era, thereby facilitating the digital transformation and upgrading of the construction industry.
