摘要：	Research is currently being conducted to improve bridge inspection practices. One potential improvement is the use of nondestructive testing equipment to supplement visual inspection. To consider the costs and benefits of this equipment, data about the accuracy of nondestructive testing results are needed. This project sought to quantify the accuracy and reliability of various nondestructive testing (NDT) equipment. Based on past research, the most common NDT techniques for steel and concrete bridges were identified. A literature review was conducted to identify any past research measuring the accuracy of these methods. A delphi survey was then conducted with experts in NDT. This survey was implemented in several rounds and asked experts to assign numbers to the accuracy and reliability of NDT techniques with which they were familiar. Results of the survey were analyzed and compared to past research.
