Anticipated Benefits
Having a digital as-built model will help us manage our infrastructure assets more efficiently throughout their life cycle. This data management strategy is aimed at providing data across multiple platforms where data can be exchanged regardless of what software is used to create it.

Final Report Abstract
The objective of this State Transportation Innovation Council (STIC) Grant study was to build on the three-dimensional (3D) Building Information Model (BIM) used as the deliverable for the construction of the Ramp B Bridge, Design Number 420, FHWA Number 700725, in the reconstruction of the I-80/I-380 interchange in Johnson County, Iowa. The Ramp B Bridge is a three-span, steel plate girder bridge supported by concrete hammerhead piers and a stub abutment. It is one of three bridges modeled as part of the original contract (Figure 1). The original model was created as part of a pilot project using Bentley’s BIM software packages Open Bridge Modeler (OBM) and ProStructures (PS). It was created as an addendum to the bridge design contract as part of an effort by Iowa DOT to explore and push the boundaries of Bentley’s BIM software as well as to investigate the benefits and shortcomings of its use during construction.
Following construction of the bridge, this STIC Grant study was proposed to further advance the BIM model developed for the pilot project by incorporating as-built information and other associated construction data. The objectives were to capture the known construction Design 420, Ramp B modifications to the design and to allow the data in the model to be used in the future for asset management applications.
