In 2002 the Florida Department of Transportation (FDOT) developed a project-level bridge management decision support model to complement the existing network-level functionality of the American Association of State Highway and Transportation Officials' Pontis. This work was done as part of a series of research projects FDOT has undertaken in recent years to adapt Pontis to its own management processes and to build useful functionality on top of Pontis to fill unmet needs. In previous efforts, FDOT had developed a new user cost model, with emphasis on accident risk; a new model of maintenance, repair, and rehabilitation costs; and a new set of transition probabilities for the Pontis element-level deterioration model. All of these models were designed to fit within the existing network-level analytical framework of Pontis. In the current project, the Pontis analysis has been significantly extended to better serve the needs of project-level decision making. A graphical decision support tool was developed to help the engineer explore the economic tradeoffs of scoping and timing inherent in project-level decisions. Developed in Microsoft Excel and Visual Basic, the tool uses Pontis network-level results for policy guidance and long-term economic consequences of actions, and draws on the Pontis inventory and inspection process supplemented with FDOT enhancements. A new analytical process was developed to generate candidate alternatives that are tailored to FDOT policies and that explore the range of practical scope and timing alternatives. Using the graphical presentation, engineers can quickly grasp the economic structure of each individual bridge and incorporate this perspective into their decision making.
