Methods for the use of Nondestructive Evaluation (NDE) test data in bridge management systems are reported. NDE data are interpreted as condition ratings. Definitions of condition states are coordinated with thresholds for properties measured in tests. Data thresholds are the boundaries of condition states. Tests are directed at particular conditions and materials. Tests offer a determination of condition of elements relative to the focus of the test. Therefore, there are redundant, overlapping determinations of condition. Tests must be selected for the elements to be interrogated and for the expected types of deterioration. The tests considered here are standard tests for the evaluation of construction materials, and the examination of bridge elements in service. While standard data thresholds are available, these are adjusted to achieve a consistent assignment of condition states for all bridge elements and for all condition states.
