摘要:针对大型复杂项目采用BIM等信息化技术提升项目协同效率正成为趋势，但预期效果差距较大。工程实践中发现应用效果的差距来自于项目管理人员对信息协同理论的认识不到位、目标不明确、实施步骤不清晰，容易忽视信息化工作推动过程中的系统性。本文聚焦大型复杂项目信息化协同平台的建设过程，通过对大型复杂项目管理与信息协同理论的梳理、协同数据流的推算以及信息传递难点的汇总，阐述了大型复杂项目信息协同的需求和必要性，提出了基于BIM的信息化协同平台的作用、功能和组建方案，并以重庆江北国际机场为例，介绍了平台的建设情况和所取得的成效。

Abstract: Large and complex projects are increasingly adopting information technology such as BIM to improve project collaboration efficiency, but some of them have not achieved the expected results. Through engineering practice, it has been found that the failure lies in the misunderstanding of information collaboration theory, the unclear goals, the undefined implementation steps, and overlooking the systematic work related to the promotion process of information technology work. This article explores the construction process of an information collaboration platform for large and complex projects. By reviewing the theories of large-scale and complex project management and information collaboration, calculating collaborative data flow, and summarizing the difficulties in information transmission, the article proposes the requirements and necessity of information collaboration for large-scale and complex projects and the function and construction scheme of the information collaboration platform based on BIM. Taking Chongqing Jiangbei International Airport as an example, this article introduces the construction of the platform and the results achieved.
