This section deals with the application of NDT techniques to buildings and civil engineering structure circumstances. The information is presented as a series of cascading tables (see Figure 10.1) supported by case histories. The first table lists the types of information that are sought for structures constructed using:
The subsequent tables link the information sought, with the appropriate diagnostic testing and inspection techniques. In these tables the geophysical methods are in bold text, but also included are alternative methods of investigation and testing, which might supply the required (or complementary) information. The geophysical methods are then summarised after the tables with comments on the effectiveness of the technique to provide the required information. Three case histories illustrate the use of the individual testing/ investigation techniques.

Table 10.1 provides a simplified guide to the nature of some of the information, which might be sought in various circumstances, for structures constructed using concrete, masonry and stone, metals and composite materials.

The following tables provide a simplified guide to the initial selection of testing procedures for each of the categories covered in Table 10.1.
