WBS作为有效地计划和控制建设工程项目的工具,表现为一种层次化的树状结构,定义了整个工程项目的结构和各层次工作范围、工程量清单。根据项目管理工作需要,对工程项目进行不同类型不同层次的分解,随着分解的深入,工作结构或工程量清单也就越具体越详细,直至满足对项目进行进度,质量,成本的控制管理,满足施工管理的各项要求。颍河特大桥工程施工管理中应用WBS原理对工程量和工程结构进行了分解,便于精细化管理,及时掌握各分项工程的进度和成本状况。
WBS, as an effective tool for planning and controlling construction projects, is characterized by a hierarchical tree structure that defines the structure of the entire project and its scope of work and bill of quantities. According to the needs of project management, different types and levels of engineering projects are decomposed. As the decomposition progresses, the work structure or the engineering quantities list will be more detailed and detailed until the control and management of the project progress, quality and cost are met. Meet the requirements of construction management. Application of WBS principle in construction management of Ying River super-large bridge decomposes the engineering quantity and engineering structure so as to be fine-grained and grasp the progress and cost status of each sub-project in time.
