As a national-level new district, Nansha New Area has a superior geographical location and advanced position. The Pearl Bay starting area is the core area of Guangdong-Hong Kong-Macao cooperation and a comprehensive service center that is built by the Nansha New Area and set high-quality construction innovation standards. In order to adapt to the planning concept and construction requirements of Pearl Bay, Pearl Bay Development Authority has developed an engineering management information system suitable for the administration′s construction project management. Starting from the visualization, dynamic, and refined management of progress of works, investment, quality, safety, operation and maintenance, and the integrated collaborative management of the development and construction of the whole district, the traditional project management model has been changed through information technology. At the same time, the information technology has proposed some new ideas for project management. This article selects six typical new ideas in the project management information system to introduce, summarizing the advantages of this management system, and hopes to provide some reference for the construction of other new districts.

As a pioneering demonstration area in the Guangdong-Hong Kong-Macao Greater Bay Area, The Pearl Bay starting area has already been deployed for the construction of a "smart city" demonstration zone. The Engineering Management Information System of the Pearl Bay Development Authority focuses on the work points of the Administration, serves the construction of the Pearl Bay starting area Project supervision and integrates "operations, management, and decision-making" to achieve the whole process supervision of project approval, design, construction, inspection, and comprehensive evaluation, which builds an information foundation for the subsequent management and operation of smart cities. Based on the concept of data fusion, this paper analyzes the data fusion method and process of the system at the data layer, business application layer, and decision application layer. The system is based on the basic construction procedure and the spatiotemporal data fusion method of map grid, which can provides a certain reference for the data integration design of smart supervision platform for engineering construction in other new districts.
