Guidelines for the Implementation of the Bridge Health Index

The goals of this research are to identify/develop tools for using the bridge Health Index (HI) in a comprehensive bridge management system and specifically for decision-making in the context of a bridge preventive maintenance program. This research will implement the bridge HI on individual bridges and networks of bridges. The Wisconsin Department of Transportation (WisDOT) would like to investigate the potential uses of the recently developed bridge Health Index within a comprehensive Bridge Management System (BMS) in general and more specifically, for decision-making in the context of a preventive maintenance program. Through literature and interviews, the Research Team will prepare an "implementation guidelines" document that describes State agencies' experiences and processes using the HI for bridge management. The scope of the guidelines will include experiences in relating the health index to preventive maintenance, implementation issues and criteria, and recommendations. The project includes quantitative and qualitative assessments of the HI for measuring the impact of preventive maintenance actions on increasing long term asset value and extending the expected life of bridges. This project addresses issues of implementation feasibility by demonstrating the health index forecasting and models possibly as a spreadsheet tool, and then illustrated with actual data from at least one region.
