Rail transit is the cornerstone of urban public transport. However, rail transit projects are cost-intensive, time-consuming and difficult to coordinate. This calls for digital upgrading of the full lifecycle control of rail transit property. This paper integrates the multi-sourced heterogeneous data in the architecture, engineering and construction (AEC) field and the geographic information system (GIS) field, and creates a technical framework coupling GIS, computer-aided design (CAD) and building information modelling (BIM) that serves the fully lifecycle digital control of urban rail transit property. The established technical integration framework, denoted as the CGB, was applied to Phase 2 of the branch line of Line 6, Chongqing Rail Transit, and optimized for the key points of full lifecycle control. The research findings shed new light on the provision of digital support to the smart development of urban rail transit.
