                  Refer AS1726-2017 Clause A2.4 for classifying soils.


                  Notes:
                  4. Hand Auger (H/A) is a portable auger and where utilised is used because of lack of access or trafficability, it is essential that the results
                     of a hand auger are confirmed once access is provided, further testing using a 4WD mounted drill rig is carried out, or stakeholders
                     shall accept the associated risk of results which may not represent the subject site conditions.
                  5. 9kg Dynamic Cone Penetrometer (DCP) can be unreliable in certain soils which may include (but not limited too), cohesive soils, soils
                     which may contain gravels with a grain size in excess of 10mm, and strata with allowable bearing pressures in excess of 400kPa.
                  6. Pocket Penetrometer (PP) readings are an unfactored field strength test and should not be assumed equates to an allowable bearing
                     pressure.
