Bridge engineers have been creating 3D models for bridges for many years. These models were mostly used for analytical purposes for advanced computations, since finite element methodology requires a 3D model. Over time, these 3D models have been evolved from simple frame models to full realistic solid models. Nevertheless, there was always a gap between analytical models needed for design calculations and physical ones used for a real representation of the bridge structure as needed for construction and maintenance.

Bentley Systems’ bridge solution is “bridging” the gap between these two models by creating a physical model of the structure with all details necessary for an accurate representation and geolocation of the structure in the real World, and using the same model for analytical purposes to perform the necessary design calculations.

Moreover, bridge engineers are facing the challenge of how to make the vast information generated by their structure useful for professionals further down the line in the lifecycle of the bridge. Sometimes, contractors and inspectors require that a 3D model is provided after the design process, but at the same time recognizing that they do not use or have the calculation or specialized CADD software used to develop the model. Moreover, they require the ability to save extra information in the same 3D model that pertains to their activities, and also allow collaboration from the multiple disciplines that may participate in a project. Then, the need of a common platform, preferably cloud base, is imperative to allow that level of collaboration for design reviews in real time.

The purpose of this paper is to present the technology available within Bentley Systems to generate, manage, and enrich the bridge 3D model with intelligent information and how it is used for construction and inspection in the areas of clearance verification, geometry and quantity reports, scheduling and construction planning.
