Abstract:With the continuous development of BIM technology, the application of BIM platform in the whole process of construction is gradually enriched. It is the essence of the BIM platform to integrate the engineering data of the full life cycle behind the platform and transfer the data to all aspects of engineering construction for application. How to collect and organize the engineering database in the full life cycle of the project and transfer it to each workflow is the focus of BIM platform construction. Taking the Urumqi Dongjinchang Elevated Bridge Project as an example, the establishment of engineering database in BIM platform is specially studied, how to collect engineering data in the design stage and construction process of the project is analyzed, and the engineering database is applied in the project management.
