Migration of Element-Level Inspection Data for Bridge Management System
In the United States, the Pontis software system, developed by the American Association of State Highway and Transportation Officials (AASHTO), has been the primary system used by State Departments of Transportation (DOTs) for bridge management. The system facilitates collection of element-level condition data and management of bridge inventories. The newly released AASHTOWare Bridge Management Software (BrM) system will replace the Pontis system and will have improved capabilities. Along with the new system, AASHTO has revised the element-level inspection guidelines to improve bridge management by providing greater inspection detail. To facilitate the adoption of the new BrM system, AASHTO provides a program, termed the “Migrator”, to convert inspection data from the Pontis elements to the new AASHTO BrM elements and definitions. The Migrator is a general rules-based program developed to convert condition state quantities and element coding. This research investigates the Migrator rules for element data by comparing the Pontis definitions to the new AASHTOWare BrM definitions for select elements in the State of Virginia. Data migration was performed for elements in each major bridge component; superstructure, substructure and deck. Modified migration rules were developed to improve agreement of condition state definitions. Additionally, deterioration models for these elements were developed with the migrated data and were compared to deterioration models developed using current Pontis data as well as migrated data using the AASHTO Migrator. This research found the Migrator is adequate for concrete elements but modifications to the migration rules produced more useful results and more consistent deterioration models for deck and other elements.
