A large percentage of bridges in the state of Iowa are classified as structurally or functionally deficient. These bridges annually compete for a share of Iowa's limited transportation budget. To avoid an increase in the number of deficient bridges, the state of Iowa decided to implement a comprehensive Bridge Management system (BMS) and selected the Pontis BMS software as a bridge management tool. ... The objective of this work was to develop an automated-computerized methodology for an integrated data base that includes the rating conditions as defined in the Pontis program.

The Iowa DOT currently owns and maintains over 4,000 bridges and culverts on the state highway system. With heightened concern for the condition of these aging structures, methods for assessing and maintaining the structural performance of in-service bridges have become vital to the preservation of Iowa's bridge network. An economical data acquisition system that is portable and can be efficiently used on bridge structures could supplement visual inspections with field-measured values. By pursuing simplicity in the system interface and installation, tests could be completed by persons with limited engineering background. This concept can prevent bridges from being replaced that are thought to be structurally deficient and help estimate bridge condition in the database. This report summarizes a research project for the Iowa Department (Iowa DOT) to develop, implement, and operate an integrated bridge asset management system for the state of Iowa. The system is Pontis, first developed in 1989 and currently used by around 45 transportation agencies, both in the United States and internationally. This system will enable the Iowa DOT to make objective, cost-effective, and timely decisions regarding bridge maintenance, rehabilitation, and replacement.

The Pontis Bridge Inspection Coding Guide was developed by the Staff Bridge Branch of the Colorado Department of Transportation. This revision includes cross references to the General Comments and Definitions necessary to provide for uniform inspection reports from various bridge inspectors and is intended to supplement the AASHTO Guide for Commonly Recognized (CoRe) Structural Elements with clarifying information and additional elements unique to Colorado bridges and structures. If conflicts occur between the guides, the AASHTO guide governs.

relies on inspectors' observations, and assessments, it is possible that one inspector will rate the condition status of an element differently than another. To eliminate subjectivity in the condition rating prediction of bridges, 'pdfplumber' and 'Tabula-py' were used to extract data sets from historical bridge inspection reports, which will serve as input in training the machine learning algorithm for predictive maintenance programs in the future. The targeted expedition of the inspection process by data collection using UAVs, 3D model reconstruction using photogrammetric pipelines, and historical report processing thus shows how this research can improve the tedious maintenance programs.

To increase the efficiency and reliability of bridge inspections, MDOT contracted to have a 3D-model-based data entry application for mobile tablets developed to aid inspectors in the field. The 3D Bridge App is a mobile software tool designed to facilitate bridge inspection processes by enabling inspectors to enter element-level bridge condition data using 3G/4G network-enabled tablet devices. The system collects information from MDOT's bridge management database, and then renders a dynamic, interactive 3D model of the desired bridge. The bridge inspector is able to record the locations and attributes of new defects in an element-level form by touch interaction and manipulation of the 3D model. The interactive model, marked up with existing defects, also allows for bridge inspectors to better visualize past inspection data. The inspector can also take pictures of the defects using the tablet's camera, as well as record comments. This gives users further insight into the progression of the defect over time. The bridge inspector is able to navigate along the bridge model just as he or she would during a normal inspection. Results can be integrated into bridge management workflows.
