CPT Interpretations The parameters selected for output from the program are often specific to a particular project. As such, not all of the interpreted parameters listed in Table 1 may be included in the output files delivered with this report. Table 1 CPT Interpretation Methods Interpreted Description Equation Ref, Parameter Mid layer Depth Depth (where interpretations are done at each point then Mid Depth(Layer Top)+Depth(Layer Bottom)/.2.0 Layer Depth=Recorded Depth) Elevation Elevation of Mid Layer based on sounding collar elevation Elevation=Collar Elevation-Depth supplied by client Avgqc Averaged recorded tip value(q.)
