• Abstract:
  In bridge inspection, the “condition rating” assigned to a structural component represents the outcome of a subjective comparison of the member’s current physical condition to its as-built condition. This evaluation is made with the aid of the various definitions of structural condition provided in the Recording and Coding Guide published by the Federal Highway Administration(FHWA) and based on National Bridge Inspection Standards (NBIS). Since a “condition rating” is usually assigned based on a visual assessment of the bridge by inspectors with varying levels of training, experience and background, the evaluation is quite biased and photographic support is needed. QuickTime Virtual Reality (QTVR) provides the capability of generating and managing an interactive high-resolution photographic record that allows bridge engineers detailed visual access to the physical condition of the bridge components in electronic format. This digital record of the bridge provides inspectors, engineers, and supervisory staff a very useful tool for planning, conducting, and reviewing the results of a field inspection. In this report, the equipment and procedures for using QTVR for documenting bridge condition is provided.
