This report "Building Information Modeling (BIM) Practices in Highway Infrastructure" from the Federal Highway Administration (FHWA) provides an example of a national-level BIM roadmap focussed specifically on highways and roads.
It presents evolving trends in BIM implementations in BIM-mature nations and their public highway infrastructure agencies. It also focuses on understanding how other countries are using BIM for infrastructure to better deliver transportation projects, manage assets, and provide related services with a view to benchmark and advance U.S. practice.
Visits were made to BIM-mature agencies in the United Kingdom, the Netherlands and Norway to discuss and examine core aspects of BIM for infrastructure implementation. The BIM development efforts of the studied agencies demonstrated clear motivation, purpose, goals, and top-line support, which recognise both the costs, and more importantly, the benefits of adopting BIM for infrastructure.
