The development and construction of a district is a systematic project with complex systems, wide coverage, heavy tasks and high uncertainty. The construction period is often difficult to grasp. This paper takes a certain project in the Shanghai Lingang New Area (hereinafter referred to as "this project") as an example. Based on the overall control mode of the project, it comprehensively analyzes the characteristics of the development and construction of the area, establishes a priority scoring matrix, and makes overall planning for the sequence of the development and construction of the area, providing strong information support for the realization of the overall construction goal and achieving good results. It provides certain reference value for the subsequent timing planning of large-scale area development.
