Abstract: With the widespread application of Building Information Modeling (BIM) in engineering, the construction industry is bound to witness a new wave of technological innovation and management upgrades. This paper studies on the Chongqing Jiangbei International Airport T3B Terminal project and conducts in-depth research on the application of BIM in the detailed construction process and collaborative management of the secondary structures. This research encompasses model maintenance, detailed drawing development, technical focal points, and management methods to guide the construction process effectively using BIM. Furthermore, corresponding coordination mechanisms and measures are formulated to ensure that the BIM detailed design results can provide effective guidance for on-site construction. Additionally, this paper summarizes the workflow, collaborative management, and application outcomes of the detailed construction of secondary structures, which successfully addresses the challenging issues encountered in BIM detailed design for secondary structures. As a result, it significantly improves engineering quality, shortens construction period, and reduces construction cost. The technological approaches, management methods, and acquired data and experiences employed in this paper are expected to be a reference for the detailed construction of secondary structures in other construction projects.
