210.4-2009 (PDF) - Guide for Nondestructive Evaluation Methods for Condition Assessment, Repair, and Performance Monitoring of Concrete Structures

This guideline will assist contractors, owners, engineers, architects, and material suppliers in the selection of nondestructive evaluation (NDE) methods for evaluating the condition of concrete structures. NDE can be a very useful method to provide quality control and assurance of repairs and long-term performance monitoring. Considerations in planning and executing an NDE program, including correlating with destructive methods, are discussed in the guideline. Guidance, including a brief synopsis of each method, is presented for selecting which NDE methods are appropriate for the concrete property/condition being assessed.
