Samtani and Nowatzki (2006) provide a summary of visual inspection during construction to observe any deflections in the wall during construction by noticing cracks, seepage, displacements, heaving, etc.</p><p><strong>Accuracy and Precision</strong></p><p>Accuracy and precision are dependent on the inspector. The inspector should be familiar with the soil nail wall construction.</p><p><strong>Adequacy of Coverage</strong></p><p>The entire wall can be inspected with daily site visits.</p><p><strong>Implementation Requirements </strong></p><p>Visual inspecting requires experience on the part of the inspector to be able to identify problems.</p><p><strong>General Comments</strong></p><p>Visual inspection does not provide quantifiable results. However, it can identify major concerns of the project based on visible problems such as cracking, seepage, and deformations. Visual inspection is applicable to performance and method approach specifications.</p></p>
