            4.3          Geology
            Available geological information 1 indicates that the site is underlain by Pleistocene age dune sand
            (Ref: Text Figure 7).

            4.4          Subsurface Conditions
            Detailed descriptions of the subsurface conditions encountered in the boreholes are provided in the
            borehole reports attached in Appendix A, along with definition sheets which describe terms and
            abbreviations used on the reports. The subsurface conditions encountered in the boreholes are
            summarised as follows:

                       Pavement (pavers/synthetic matting) – 20 mm to 60 mm thick; then
                       Fill – comprising mostly very loose, silty and gravelly sand to between 0.4 m and 1.2 m BGL;
                        overlying
                       Aeolian Sands – comprising poorly graded sands that were loose to depths of between 1.1 m and
                        2.5 m BGL in boreholes BH2 and BH3; then becoming medium dense (from 0.2 m BGL in BH1)
                        and increasing to dense below depths of about 3.1 to 4.1 m BGL.
