Based on the characteristics of 3D collaborative design and aiming at the problems existing in the 3D collabora-tive design and quality control, this paper mainly focus on the establishment of quality control process in 3D collaborative design in construction, taking Beijing-Shijiazhuang Section’s 3D design program in the middle route project of South-North Water Diversion as an example, to achieve the purpose of collaborative arrangement and quality control in different construction environment and different construction's complex in the realistic design.%针对水利水电工程在三维协同设计中质量控制易出现的问题,以南水北调中线工程京石段三维设计项目为例建立了工程中三维协同设计的质量控制流程,实现了实际设计项目中对不同工作环境及不同复杂度任务的协同布置及质量控制。
