Abstract: To solve the problems of tight construction cycle, high construction safety requirements, and multiple sources of management data in municipal engineering involving railways, this paper proposed a digital design and integrated delivery solution based on BIM+GIS. Based on the municipal engineering involving railways in Jiangping East Road of Yangzhou City, the paper customized development of a universal full life cycle integrated delivery system for participating units. The system implemented functions such as real scene digital twin, important construction site navigation, virtual reality simulation driving, etc., providing visual tools for full chain communication and decision-making of project participating units, greatly improving the quality of engineering construction and project management efficiency, and can provide technical references for related municipal engineering involving railways.
