Abstract: In order to resolve problems of high resource consumption, labor shortage and low information integration in the existing extensive construction mode of railway bridges, based on BIM (Building Information Modeling) and GIS (Geographic Information System) technology, this paper designed and developed the railway bridge information construction management platform. The platform implemented the functions of three-dimensional visual project progress management, safety management, quality management and so on. The paper took spring cloud as the technical framework to develop a distributed system with microservice architecture characteristics, study the key technologies of 3D scene cache preprocessing and data management based on engineering structure decomposition. The platform was applied to the Changqing Yellow River Bridge project of Zhengji (Zhengzhou-Jinan) railway. The results show that it can improve the production efficiency, management efficiency and decision-making ability of the construction site.
