48The image depicting DCP equipment in operation and schematic drawing can be found inFigure 22. The number of weight drops and depth of penetration were recorded whereas theobtained test penetration results were consequently converted into Penetration Index data(mm/blow).HANDLE8kgHAMMER0.575mDRIVEANVILREFERENCEROD W/SCALESTEELROD1mVARIABLE16mmCONE60°20mm(a)(b)Figure 22: DCP equipment (a) in operation in test bed (b) schematic drawingSince the excavation of the test bed material was to be performed to the depth of 610 mm, theDCP level of penetration had to be extended to a depth of 610 mm as well. Occasionally thepenetration depth was extended to the elevation of 700mm, however was concluded to be notsufficient to provide description to stiffer layer of soil beyond elevation of 610 mm. DCPprofiles that were obtained for all stages of single and group of pier testing can also be foundin Appendix.
