4.4          Subsurface Conditions
Subsurface conditions encountered in the boreholes are summarised below, with borehole reports providing
detailed descriptions given in Appendix A.

Subsurface conditions encountered in the boreholes comprised, very loose to loose silty sand fill to 0.6 m
BGL (in borehole BH1 only), overlying natural loose sand becoming medium dense below depths of 1.2 m
to 1.4 m BGL and grading to dense below 3.6 m to 4.3 m BGL.

Photographs showing cuttings from the boreholes which illustrate the typical subsurface conditions
encountered are given in Text Figure 8 and 9 below and overleaf
A tabulated summary of the encountered subsurface conditions is also presented in Table 1 on the following
page.
