Synthesis of Information Related to Highway Practices. Topic 52-02. Using Bridge Element Data in Asset Management Decision Making

State departments of transportation (DOTs) have been transitioning to using element inspection data for documenting bridge conditions since 2014. This condition assessment methodology offers a significant opportunity to improve the timing, cost efficiency, and accuracy of bridge maintenance, rehabilitations, and replacement decisions. However, there is no standard guidance on achieving those benefits. Bridge management platforms such as AASHTOWare BrM can combine these data with other inputs to forecast future conditions and recommend optimal plans for a portfolio of bridges. Anecdotal evidence suggests that state DOTs that receive the inspection reports are taking numerous approaches to using the data. Many DOTs rely on general condition ratings reported to the National Bridge Inventory for bridge maintenance and investment decisions. Still others have begun to incorporate the element level data into those decisions. The objective of this synthesis is to document current state DOT practice and experience regarding collecting and ensuring the accuracy of element level data. The synthesis will also examine how DOTs are using the data from inspection reports. Information to be gathered includes (but is not limited to): (1) Practices for collecting element level data (e.g., collection software, nondestructive evaluation methods); (2) Practices and methods for ensuring the accuracy of the data collected; (3) DOT business processes that use element level data (e.g., project scoping, maintenance, bridge asset management modeling and analyses, performance measurement and reporting); and (4) Aspects of DOT bridge management systems that use element level data (e.g., deterioration models, action types, action costs, decision rules, performance indices). Information will be collected through literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
