       WATER
       GROUNDWATER NOT                          The observation of groundwater, whether present or not, was not possible due to drilling water,
       OBSERVED                                 surface seepage or cave in of the borehole/test pit.
       GROUNDWATER NOT                         The borehole/test pit was dry soon after excavation. However, groundwater could be present in
       ENCOUNTERED                             less permeable strata. Inflow may have been observed had the borehole/test pit been left open

       SAMPLING AND TESTING
       SPT                             Standard Penetration Test to AS1289.6.3.1-2004
       5,4,10 N=14                     5,4,10 = Blows per 150mm. N = Blows per 300mm penetration following 150mm seating
       30/65mm                         Where practical refusal occurs, the blows and penetration for that interval are reported
       RW                              Penetration occurred under the rod weight only
       HW                              Penetration occurred under the hammer and rod weight only
       HB                              Hammer double bouncing on anvil

       BDS                             Bulk disturbed sample
       SV                              Field shear vane test expressed as uncorrected shear strength (sv = peak value, sr = residual value)
       PP                              Pocket penetrometer test expressed as instrument reading in kPa
       U50                             Thin walled tube sample - number indicates nominal sample diameter in millimetres
