Book Description
This report summarizes information on condition assessment of in-service wood, including visual inspection of wood and timbers, use of ultrasound and probing/boring techniques for inspection, and assessment of wood and timbers that have been exposed to fire. The report also includes information on assigning allowable design values for in-service wood.

Book Description
Deterioration of an in-service wood member may result from a variety of causes during the life of a structure. Periodic inspection of wood used in structures is important for determining the extent of deterioration so that degraded members may be replaced or repaired to avoid structural failure. Inspection professionals use a wide variety of techniques to assess the condition of wood in service. Visual, mechanical probing, and stress wave or ultrasound-based techniques are all used either individually or in combination by inspectors. Although these techniques are based on solid technical information and supporting research, prior to publication of the Wood and Timber Condition Assessment Manual in 2004, no practical, comprehensive manual provided information on inspection of wood in service. The Wood and Condition Assessment Manual was prepared to address this need. The manual was prepared from numerous research studies, inspections, and lectures dealing with assessing the condition of in-service wood and timber. It was intended for inspection professionals. A concerted effort was made to provide clear and concise explanations of various aspects of inspecting in-service wood and timber. To this end, a number of photographs and drawings obtained from actual inspections were included. The 2004 Wood and Timber Condition Assessment Manual proved to be a widely used reference document and a primary technical source for inspection professionals worldwide. User feedback included many positive comments about description of the various inspection tools available and post-fire assessment of structural wood members. Users did express a strong desire to have information on the estimation of allowable design values for in-service wood in future editions.

Book Description
Nature's engineering of wood through genetics, wind, and weather creates a wide variability in wood as a material. Consequently, manufacture and users of wood products are frequently frustrated in dealing with the forest resource. Manufacturers sometimes argue that wood is difficult to consistently process into quality products because of the wide range of properties that exist in this raw material. Users of wood products can be equally frustrated with the performance variability found in finished products. Nondestructive evaluation (NDE) technologies have contributed significantly toward eliminating the cause of these frustrations. NDE technologies have been developed and are currently used in lumber and veneer grading programs that result in engineered materials that have consistent well-defined performance characteristics. This brief volume explores some of the processes that are used to manufacture wood, including green wood technology and provides a bit of history to wood production and its uses too.

Book Description
Stress-wave nondestructive evaluation (NDE) techniques are used widely in the forest products industry--from the grading of wood veneer to inspection of timber structures. Inspection professionals frequently use stress-wave NDE techniques to locate internal voids and decayed or deteriorated areas in large timbers. Although these techniques have proven useful, little information exists concerning the relationship between stress-wave parameters and deterioration observed as a consequence of marine borer attack. In this pilot test, we examined the relationship between stress-wave transmission time and the quality of wood in Sitka spruce and western hemlock logs that had varying degrees of deterioration as a consequence of attack from marine borers. Stress-wave transmission time, perpendicular to grain, was measured at several locations on each log. The logs were then sawn into lumber, which was then visually evaluated. A relationship was observed between stress-wave transmission time and deterioration of the logs and the yield of lumber from the logs.
