• Abstract:
  Following its adoption of the new AASHTO Bridge Element Inspection Manual, the Florida Department of Transportation (FDOT) has been collecting bridge element condition data in order to use the AASHTO’s Bridge Management (BrM) software. Now, to aid the Department in satisfying the various federal requirements and prepare for anticipated changes at the national level in the bridge inspection and management standards, the FDOT needs to re-calibrate the core BrM models and tools, including the element deterioration models, risk models, the translator model, and cost models. This study has developed deterioration models for forecasting bridge element condition within the analytical framework of the BrM and explored the revision of the FDOT’s environmental classification scheme for its bridge inventory. Considering the natural and man-made hazards that are unique to Florida, risk models were developed by estimating at each bridge location, the likelihood of occurrence of the hazard, the likelihood of service disruption, and costs of the associated consequences. To enable conversion of bridge element condition data to the FHWA’s NBI ratings, a new NBI Translator was developed, with the focus on five bridge components: deck, superstructure, substructure, culvert, and channel. Finally, in response to the decreasing availability of cost data for bridge maintenance, repair and rehabilitation (MR&R) activities, this study developed unit costs based on the available historical costs (bridge work orders and the bid unit prices) and also formulated a methodology for developing crew-based cost estimates.
