摘要:广州白云国际机场扩建工程作为超大型公共交通枢纽建筑，单体建筑面积达68万m²，涉及20多个专业，各种专业设备错综复杂，对于BIM技术的应用实施是一次高难度的挑战。本项目通过多种技术手段克服困难，将BIM作为工程项目管理和技术手段，覆盖设计与施工组织管理的各个环节，包括协同设计、管线综合优化、深化设计、施工组织、进度管理、成本控制、质量监控等，保证了项目的成功实施，提高了工程建设质量和项目综合管理水平，实现项目全生命周期内的技术和经济指标最优化。

Abstract: Guangzhou Baiyun International Airport expansion project is a very large public transport hub construction, with single building area of 680 thousand square meters, involving over 20 specialties. All kinds of specialized equipment are complex, which raises a highly difficult challenge to the implementation of BIM technology. This project adopted various techniques to overcome the difficulties. BIM, used as project management and technical means, is involved in each link of design and construction management, including the collaborative design, comprehensive optimization, pipeline design, deepening the construction organization, schedule management, cost control, quality control, etc. to ensure the successful implementation of the project, which has improved the quality of the engineering construction and integrated project management level, and achieved optimization of technical and economic indicators during the entire project life cycle.
