Deterioration and Cost Information for Bridge Management

This study applies contract bid tabulations and element‐level condition records to develop element‐level actions, costs for actions, transition probabilities for models of deterioration of bridge elements, and transition probabilities for improvements to elements due to actions. The information on actions, costs, and transition probabilities is input to a Pontis BMS bridge database. The study uses transition probabilities for element deterioration to compute the number of years to possible loss of safety in bridges, and to compute the number of years for inspection intervals. It examines variations in costs of actions and deterioration of elements among Colorado Department of Transportation (CDOT) regions. A set of software applications was developed to handle bid tabulations, compute costs of actions, compute transition probabilities, and mediate the steps needed for movement of data into and out of Pontis BMS. An implementation plan is included with suggestions regarding: merging the Pontis bridge database with CDOT’s OnSys bridge database; developing procedures for element‐level tracking of repair and rehabilitation work on in‐service bridges; developing tools outside of Pontis for decision support for bridge projects.
