Application and research for digital delivery of bridge engineering design-construction model and data transfer based on IDM

In response to the inconsistent delivery results, information depth, model formats, accuracy, and fragmentation in the implementation process of digital delivery in bridge engineering, a set of standards for the transmission and delivery of design and construction data for bridge projects was developed based on the standard specifications of information data in the application process of BIM technology in bridge engineering, referring to ISO 19650 Information Delivery Manual. Taking a certain bridge project as an example, the application practice of information model deepening design, delivery preparation, deliverables, delivery coordination, delivery, and review was carried out. The results indicate that the transmission and delivery of design and construction data for bridge engineering should focus on the deepening design of concrete structures, steel structures, reinforcement, and temporary works, which can effectively promote BIM collaboration among multiple stakeholders in the bridge engineering BIM system and the continuous accumulation and transmission of data throughout the lifecycle.
