According to surveys conducted by FHWA, 39 states have subscribed to the software. Although the current implementation licensing status is well documented, application of the software by individual states varies considerably. Some states are using Pontis simply as a place to store inventory data, while others are using the modeling capability to support decisions. At the 8th Annual International Bridge Management Conference (IBMC) held in 1999, the FHWA reported that seven states indicated that they were using Pontis as part of the bridge management process. None indicated exclusive use of Pontis in the development of bridge projects for the Statewide Transportation Improvement Program (STIP). Continued search of the literature since 1999 indicates a great deal of work by states in implementing Pontis, but limited success in using Pontis as the primary project selection tool for development of the STIP. Oregon has maintained bridge inspection condition information at the element level in Pontis since 1993. In 1999, Oregon’s project selection method integrating inspection data from Pontis with other bridge condition data—specifically nondeterioration-based needs, including, as examples, seismic, scour, and functional deficiencies—was described in a paper given at the 8th IBMC. At that time, Oregon DOT (ODOT) linked various data collections to identify projects in 12 categories. Data primarily from Pontis were used to select problem bridges in the substructure, superstructure, and deck condition categories. Data outside of Pontis were used to select problem bridges in the seismic, scour, bridge rail, deck width, load capacity, vertical clearance, paint, coastal bridge (cathodic protection), and movable bridge categories. Outside of its use as a repository for inspection data, ODOT’s efforts to implement Pontis through development of the deterioration and cost models was derailed for a period of about 5 years due to reaction to shear cracking in reinforced concrete deck girder bridges and a major reorganization of the Highway Division, including the Bridge Section. As a result of this period, greater emphasis has been given to load capacity on freight routes and route continuity, moving away from a strictly “worst first” project selection process. Increases in the costs of traffic mobility and project staging have also influenced the popularity of targeting route segments for repair and replacement projects. Beginning in 2006, ODOT resumed efforts to implement Pontis. This report outlines practical aspects of progress and challenges in implementing Pontis while attempting to maintain the comprehensive nature of the 12-category bridge management system in the STIP development process and implement a corridor-based approach to project selection. The authors discuss the apparent difficulty in implementing Pontis simultaneously for cross-asset management resource allocation and project-level decision making.
