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%.
