Abstract:Building Information Modeling (BIM) is a collaborative work method for structuring, managing, and using digital data about transportation assets throughout their lifecycle. Implementation of BIM involves establishing data and process standards, policies, tools and technology, people, and organizational structure. This research identifies traditional workflows that could be transitioned to BIM-based workflows to gain efficiencies and improve productivity. Ten process workflows from planning, survey, design, construction, and asset management are analyzed to identify the data modeling, management, and use opportunities. Additionally, artifacts to deploy BIM-based workflows are identified, including business process models, data terminology, classification systems, object-type libraries, information needs, information delivery manuals, information exchange specifications, model view definitions (MVD), and sample digital model and data to facilitate construction. For development and administration of these BIM artifacts, creation of a centralized BIM transportation library (CBTL) is suggested. The CBTL is presented as a repository used to maintain open standards-based BIM artifacts in a version-controlled environment. An architecture for an CBTL was developed based on the metadata model for libraries in The Open Group Architecture Framework. Deployment of a recommended open standards-based national repository is suggested so stakeholders can use the content in the repository and contribute to its development. In addition to a CBTL, the concept and vision for potential deployment of State BIM transportation libraries is presented.
