<p><p><strong>Reference(s):</strong></p><p><em>Holtz et al. (2008)</em></p><p><strong>Method Summary</strong></p><p>Piezometers should be installed to indicate the magnitude of excess pore pressure developed during construction. Piezometers can be of any type, such as open pipes or vibrating wire sensors.</p><p><strong>Accuracy and Precision</strong></p><p>The monitoring of pore pressures for construction over soft soils is a well-established procedure for embankment construction. This method does not provide an indication for the quality of the construction.</p><p><strong>Adequacy of Coverage</strong></p><p>State transportation departments typically identify the location and depth of piezometers to be installed during construction.</p><p><strong>Implementation Requirements </strong></p><p>Piezometers are commonly used by all transportation departments.</p><p><strong>General Comments</strong></p><p>Piezometers are an essential part of monitoring construction of embankments over weak soils. Piezometers that are monitored before and during construction can measure excess pore pressure build-up and dissipation which can characterize consolidation and shear strength gain in the foundation soils.</p></p>
