The concept of CIM (City Information Modeling) promotes information modeling for smart cities based on the integration of the Geographic Information System (GIS) and Building Information Modeling (BIM). According to the Urban Development and Construction Project, by 2030, Hue City, after being expanded, will have a total area that is five times larger than the current area, and the needs related to construction are very high. Therefore, it is vital to have effective data integration for construction supervision in urban areas. Archived data systems are mainly used internally and only for management expertise. Open data regulation and accompanying digital infrastructures are required to move towards greater digitization, synchronization, and integration of data. This study is based on data provided from 2020 to 2023, which includes four main pieces of information: address, floor area, number of floors, and time of building permit registration. For BIM data, a higher hierarchy of access rights is assumed. The research team built 3D GIS data based on the 3D photogrammetry method of drones combined with Google Earth satellite images. Initial research results have shown the process and warnings in urban construction supervision. In addition, this study also pointed out several additional requirements in the synchronization of coordinate data, information that should be included in the construction permit application for the effective integration of BIM and 3D GIS in urban construction supervision and other applications for the Hue City of the future.
