Based on the definition of BIM and a review of multiple sources, we can identify the key advantages of BIM technology: visualization, collaboration, optimization, graphing, full lifecycle management, and parameterization. This article specifically examines the benefits of BIM technology in bridge engineering.
1. Visualization: The WYSIWYG Model
As buildings and structures become increasingly complex, traditional methods relying on two-dimensional drawings struggle to convey information clearly and are prone to errors during transmission. Two-dimensional drawings no longer meet the needs of modern projects. During the operation phase of bridges, BIM enables an automatically generated visual information model by integrating engineering component data. This enhances communication and coordination among project stakeholders. The entire process is visualized within the BIM system itself—not merely through renderings or reports. Every action throughout design, construction, and operation can be displayed visually, allowing users to simulate scenarios and make optimized decisions.
2. Information Completeness
BIM models encompass comprehensive details about facilities, integrating data from all project participants, various disciplines involved in construction drawing design, and different phases of project execution. Thanks to network technology, information can be shared and coordinated seamlessly. For large-scale bridges, this includes integrating manual inspections, fundamental data, and health monitoring systems, facilitating information sharing among bridge management, monitoring, and research units.
3. Information Relevance
Any change to a parameter within the BIM model automatically updates all associated elements. For instance, using Revit software, if the width of a window is modified in the building’s top view, the window’s width will simultaneously update in the elevation view. This real-time correlation significantly enhances work efficiency and prevents inconsistencies across different perspectives.
4. Information Consistency
Throughout the entire lifecycle of a facility, BIM ensures consistent information across all stages. Data needs to be entered only once and can be used or extracted at various phases, promoting smooth information exchange and sharing. For example, during the operation and maintenance phase of a bridge, there is no need to recreate the BIM construction model; instead, it can be integrated into the BIM operation and maintenance model using appropriate platforms and tools.
