Abstract: While the wood nondestructive testing (NDT) community continues to offer and improve the technology and tools for identifying decayed wood in structures, our experience has been that the use of these technologies by design professionals has not kept pace with advancements. Rather, design professionals typically rely on rules of thumb and engineering judgment to specify the extent of wood removal. This paper presents a qualitative guideline narrative for design professionals recommending wood removal extents. The framework is based on the notion that the extent of wood removal should be commensurate with the level of confidence in the method used to determine the extent of decay together with the measures used to prevent future decay. While testing of new and developing NDT technologies may continue to be necessary to update these guidelines, the authors hope that this framework will serve for continued dialog between the research community, wood NDT equipment manufacturers, and design professionals.
