• Abstract:
  The New York State Department of Transportation (NYSDOT) maintains an inventory of over 17,000 highway ; bridges across the state. As per New York State’s Uniform Code of Bridge Inspections, all bridges in New York ; State are inspected biennially, or more often as necessary. Bridge inspectors are required to assign a condition ; rating for up to 47 structural elements of each bridge, including 25 components of each span of a bridge, in addition ; to the general components common to all bridges based on visual inspection of these elements. The bridge ; condition rating scale ranges from 7 to 1, 7 being new and 1 being in failed condition. In addition to this, ratings 8 ; and 9 are assigned to cases “not applicable” and “condition and/or existence unknown”. The objectives of this ; research have been to (1) conduct a detailed evaluation of the consistency of inspection ratings, and (2) provide ; recommendations for improvements to bridge inspection procedures and training to improve consistency, whenever ; possible. A broader outcome of the research has been the development of knowledgebase on factors affecting ; consistency of bridge ratings. These research objectives have been achieved through a detailed and comprehensive ; literature review on inspection practices and the NYSDOT bridge inspection program and, development and ; evaluation of consistency of the bridge inspection ratings through the inspection of 4 selected bridges by 21 ; inspection teams. Numbers of bridges and inspection teams have been selected to generate statistically sufficient ; data for the evaluation of consistency of inspection of different bridge elements. A detailed and quantitative ; evaluation of consistency of inspection ratings of different bridge elements has been carried out through the analysis ; of inspection data. Results show that the overall consistency of ratings of different elements is more than 90%.
