Bridge Information Modeling (BrIM)

Times are changing in the bridge design industry. Uncertainties and inefficiencies within the old timeworn 2D approach have engineers performing redundant tasks, reworking tedious calculations and spending time updating plan sheets when unanticipated design changes occur. This results in wasted hours, inflated project budgets and less than optimal designs.

Pennoni understands the benefit of modeling realistic and constructible bridge projects regardless of the project scope to provide an accurate design and avoid potential conflicts. We have been early adopters of Bridge Information Modeling (BrIM) to streamline our bridge design process. Often referred to as “BIM for Bridges”, BrIM is quickly becoming an effective tool in bridge engineering and construction. Pennoni offers an efficient BrIM design process that can be used throughout all the phases of the bridge lifecycle, including concept, design, construction, and operation and maintenance.

Our BrIM process produces 3D information rich models for roads and bridge structures. Having access to an accurate 3D model of the project allows us to improve the design in terms of efficiently producing drawings, generating accurate quantities, evaluating constructability, and fostering collaboration. We can more easily and effectively accommodate design changes and evaluate alternatives. The 3D models are also used directly as part of a refined analysis or for visualization efforts. A direct result of our BrIM process is that it acts as a secondary quality control – helping to minimize errors and increases the overall level of quality in the project deliverables.

Pennoni has developed and maintains BrIM procedures, standards, and workflows for bridge design projects that conform to the standards and requirements of the agencies we work with. The way bridge design is done is quickly changing. Pennoni is not only ready, we are leading the effort as the industry adopts to this change.
