Abstract:

The urban rail transit construction monitoring has some shortcomings such as data isolation, single display form, untimely informing and processing of early warnings. As a result, combined with BIM and GIS technology, a suit of informatied management process and data organization scheme of construction monitoring data is proposed based on GIS and BIM technology, and a construction monitoring system for engineering construction management is developed, so as to solve the problems of construction monitoring data integration, display, warning and secondary warning. The input, storage, processing, 3D display and warning of monitoring point data and daily monitoring data have been realized. By integrating with a self-developed construction project management platform based on BIM and GIS technology, the system has been successfully applied to Qingdao Rail Transit Line No. 8. By interacting with model browsing, progress control, project quantity management, video monitoring and other functions, the management efficiency, safety and quality level of site construction can be improved.

Key words: urban rail transit, construction monitoring, GIS, BIM, integration
