BIM Application in Steel Structure Engineering for Passenger Terminal and Comprehensive Transfer Center of Beijing New Airport

The project of Beijing New Airport possesses characteristics of complicated steel structure, huge volume and high-requirements in construction progress, so it is necessary to use BIM technology to solve difficulties in steel structure construction. This paper mainly focuses on the in-depth BIM application in the steel structure engineering in areas of deepening design, collision inspection, construction scheme optimization, virtual pre-assembly, and etc. The project attaches great importance to equipping professional BIM development team, cooperating with relevant IT developers, independently developing BIM project management platform, integrating model information and processing data, and comprehensively tracing project construction status. The works above have greatly improved the management efficiency, and reduced the unclear responsibilities in the process of project implementation, as well as the project operation cost, which provides a solid guarantee for the timely delivery and operation of Beijing New Airport. This project also provides a useful reference for enterprises to realize the BIM-based technology-driven transformation path.
