During the bridge operation and maintenance phase, a significant amount of data accumulates after design and construction. Traditional bridge operation and maintenance processes often suffer from the loss of key information due to differing work priorities among participants during earlier stages. This issue is particularly critical for bridge projects spanning long time periods, as bridges typically serve for decades or even centuries. Therefore, preserving and managing bridge information is essential for ensuring the bridge’s long-term health and functionality.
A bridge information management system based on Building Information Modeling (BIM) technology enables comprehensive management of bridge data throughout the entire lifecycle—from construction to operation and maintenance. Currently, the main applications of BIM technology in bridge operation and maintenance include:
1. Bridge Performance Testing: The BIM platform integrates with systems such as sensors to enable real-time monitoring of structural data and performance indicators, allowing users to assess the current condition of the bridge instantly.
2. Multi-System Collaboration: BIM works alongside specialized software like risk assessment tools, health monitoring systems, and Geographic Information Systems (GIS) to create interactive interfaces. These connections enable real-time warnings and protection measures. A BIM-based collaboration platform consolidates information from various departments involved in the project, establishing a centralized operation and maintenance database. This database records essential bridge information—including geometric data, performance parameters, owner details, and responsible personnel—forming a collaborative workspace where all stakeholders can exchange and share resources efficiently.
While implementing BIM technology in bridge operation and maintenance may initially require building a complex collaborative platform with considerable effort and cost, the long-term benefits are substantial. Compared to traditional methods, BIM reduces overall operational costs by providing a scientific basis for maintenance and enabling automated management. This approach streamlines daily bridge management and lowers labor expenses, ensuring safer and more efficient bridge operation over time.
