Abstract: With the development of infrastructure construction in China, the number of bridges is increasing rapidly, putting a strain on operation management and structural maintenance. Bridge Information Management System (BIMS) uses information and digital technology to ensure the maintenance of the bridge in long-term operation. However, large-scale bridge models are large in size, complex in structure, rich in information and occupy more computer resources, which harms performance of the BIMS. This paper aims to design and develop a bridge information visualization management system based on Building Information Model (BIM). The geometry and material information for the model is extracted from the IFC by the secondary development of Revit. The lightweight method of the bridge model is studied and implemented, and the model volume is reduced to less than 20% by using the lightweight algorithm. Also, a Web-BIM-oriented model visualization scheme is proposed to render the lightweight model into the browser. This system integrates BIM with the Internet of Things (IoT) and contains information visualization, human-computer interaction and user collaboration. Such a BIMS can effectively relieve the pressure of bridge operation and maintenance, while also providing managers with a safe and reliable platform.
