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:
▪   Topsoil – comprising very loose to loose sand to depths of 0.1 m to 0.2 m BGL; then
▪   Natural Sands – comprising poorly graded sands mostly being loose to medium dense to depths of
    between 1.1 m and 1.3 m BGL; then becoming medium dense and increasing to dense below depths
    of about 3.3 m to 3.8 m BGL in boreholes BH1 and BH2.
Table 1 below summarises the subsurface profile in each borehole.
