This report extends on the work previously conducted by Austroads in investigating the development and implementation of a national automated bridge assessment framework. The work outlines the ongoing validation works and recommends a set of activities to assist in the deployment of the framework.

Additionally, a roadmap to implementation has been prepared to highlight key areas which must be addressed to ensure the framework can be deployed.
