摘要:北京新机场项目钢结构类型复杂、体量庞大以及施工进度要求高，有必要利用BIM技术破解钢结构施工过程中的难题。本文聚焦于钢结构工程的深化设计、碰撞检查、施工方案优化、虚拟预拼装等方面的深入应用，通过配备专业的BIM开发团队，协同相关IT开发人员，自主开发BIM项目管理平台，整合模型信息及处理数据，全面追溯项目建造状态，极大地提高了管理效率，减少了项目实施过程中职责不清的问题，降低了项目运营成本，为实现北京新机场按期投运提供了坚实的保障，也为企业实现基于BIM技术驱动转型路径提供了有益的借鉴。

Abstract: 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.
