A “walking inspection” should be conducted by the foreman and the engineer to observe any deflections in the wall during construction and any additional cracks, seepage, displacements, heaving, etc.</p><p><strong>Accuracy and Precision</strong></p><p>Accuracy and precision of the inspection are dependent on inspector’s experience.</p><p><strong>Adequacy of Coverage</strong></p><p>It is not difficult to visually inspect a large area.</p><p><strong>Implementation Requirements </strong></p><p>Some experience is necessary to recognize problem areas.</p><p><strong>General Comments</strong></p><p>Visual inspection does not provide quantifiable results. However, it can identify major concerns with the project based on visible problems such as cracking, seepage, and deformations.</p></p>
