Intelligent Management-control Method and Platform Application for Rail Transit EPC Projects

Abstract

Objective Targeting the technical challenges including difficult implementation of refined management, lagged progress control information, heavy safety supervision tasks, and difficulties in achieving digital handover in rail transit engineering, procurement, and construction (EPC) projects, an intelligent management-control method and the key technologies for platform application of the EPC projects based on BIM (building information modeling) is proposed. Method The main management pain points and difficulties existing in EPC projects are analyzed. Business requirement analysis and overall architecture design for EPC based on system engineering and agile development theories are carried out. Key technologies such as lightweight modeling and 3D visualization, model-plan automatic association, and dynamic construction organization simulation based on data iteration are investigated. The above EPC management platform based on BIM is specially developed and applied to rail transit projects. Result & Conclusion The developed 12 intelligent design and smart modeling plugins can significantly improve model quality and modeling efficiency, and effectively address issues of graph-model consistency. The dynamic construction organization simulation technology based on data iteration can fully utilize actual data to predict project progress trends, enabling proactive corrective measures and effective control of overall engineering schedule objectives for large-scale projects. Work orders are used for approving critical on-site operations, and technological means such as IoT (Internet of Things) are comprehensively integrated to regulate construction personnel, material, and equipment configuration, as well as acceptance management processes, constraining all parties involved to correctly follow supervision and management procedures, thus ensuring the effectiveness of execution mechanisms and the reliability of information delivery while achieving digital handover throughout project full process.
