This test is performed by monitoring surface wave velocities at various distances away from the impact source to compare with local specifications on what is acceptable.</p><p><em> </em><strong>Accuracy and Precision</strong></p><p>Information regarding accuracy and precision of this test method was not discussed in the references cited above.</p><p><em> </em><strong>Adequacy of Coverage</strong></p><p>The coverage depends on how many sensors are used to detect the ground vibrations.</p><p><strong>Implementation Requirements </strong></p><p>Implementation of the technology requires specialized equipment and trained personnel.</p><p><em> </em><strong>General Comments</strong></p><p>The test method is used only as a QC measure to help mitigate disturbance to nearby structures. It does not provide any measurement to assess the compacted soil.</p></p>
