Bridge information modeling (BrIM), or BIM for bridges, is emerging as an advanced methodology for the bridge design and construction industry.
FREMONT, CA: Over the past few years, the popularity of BrIM is increasing. Many US State Departments of Transportation are incorporating BIM workflows for bridges. BIM is a widely used tool for engineers and construction enterprises for enhancing the level of design and construction information, reaching higher levels of collaboration, and streamlining project delivery.

Progressive consulting firms and leading DOTs (Department of Transportation) are enjoying the benefits of innovative, collaborative software applications for eradicating conventional workflows, where roadway and bridge designers work in silos with very less information sharing or reuse of data.
Conventional, non-interoperable workflows develop an array of disconnected models, which includes visualization models form marketing or public information purposes, structural analytical models for design calculations, and CAD models for geometry verification. Any updates or changes to these models should be done independently, resulting in a workflow, which is prone to data entry errors and diminished data ownership and alterations tracking. These situations result in decreased productivity, as well as liability conflicts.
Digital project delivery with BrIM
Making use of 3D smart models for representing physical bridge information provides owners of bridge assets with the opportunity to utilize digital project delivery, which includes virtual assembly, 3D visualization, network-level study, automated machine control, fast routing and permitting, and smart inventory as a routine part of asset management and project development.
BrIM covers the creation of a smart physical 3D model as well as establishes an ambiance for all the applications needed for bridge design to interoperate and proficiently exchange information. Thus, the intelligent 3D model becomes the only source of information for the project, enabling distinct engineering disciplines and sub-disciplines to retrieve particular data and updating the 3D model.
Since BrIM practices become mainstream, it is evident that many potential information exchanges happening over any bridge’s lifecycle, i.e., spanning design, construct, and management phases, can achieve considerable value by leveraging 3D intelligent models.
The true value of BrIM lies in the virtual eradication of 2D plans and the transformation to a fully digital solution, thus adding more information, such as design specifications, material descriptions, reports, and geotechnical data for making the model more intelligent.
