<p><p><strong>Reference(s):</strong></p><p><em>Holtz et al. (2008)</em></p><p><strong>Method Summary</strong></p><p>The site should be surveyed on a specified regular schedule in order to monitor and record fill placement elevations. Other benchmarks can be set during construction to monitor movement of benchmarks. This method is often used in conjunction with traditional settlement plates.</p><p><strong>Accuracy and Precision</strong></p><p>Survey control allows for documentation of filling rates and locations. This method does not provide an indication for the quality of the technology.</p><p><strong>Adequacy of Coverage</strong></p><p>State transportation departments require survey control on embankment projects over weak soils.</p><p><strong>Implementation Requirements </strong></p><p>Survey control is commonly used by all transportation departments.</p><p><strong>General Comments</strong></p><p>Survey control is an essential part of monitoring construction of embankments over weak soils.</p></p>
