Abstract: With the rapid advancement of intelligent construction technology, Building Information Modeling (BIM) has become an important means of modernizing the management of complex bridge engineering and construction. As a bridge type characterized by structural complexity and high technical difficulty, the construction process of cable-stayed bridges involves multidisciplinary collaboration and refined management. Traditional management approaches are often inadequate to meet the demands of high efficiency and high precision. In this context, this paper takes the Yazuiyan Bridge project in Huaihua City as a practical case to systematically explore the refined management and control approach of intelligent construction for cable-stayed bridges empowered by BIM technology. Through technical means such as 3D restoration of site conditions, pile position review, and construction simulation of complex joints, combined with an intelligent management platform for collaborative control of construction progress, quality, safety, and cost throughout the construction process, the study demonstrates that the integrated application of BIM technology in this project achieved a 100% accuracy rate in pile coordinate verification, reduced the project report generation cycle from several days of manual work to several hours of automatic system generation. Furthermore, through BIM-based quantity verification, deviations in design quantities were corrected, concrete procurement costs were strictly controlled, and core indicators such as main girder elevation, cable force, and pylon deviation after cable tensioning all met design standards. Based on dynamic analysis of lifecycle data through BIM, a data-driven decision-making system was established for the project. The findings indicate that the deep integration of BIM technology and intelligent management platforms has formed a replicable and scalable intelligent construction management system for cable-stayed bridges, providing an important reference for similar engineering projects in terms of technology integration, management collaboration, and process optimization.
