4.3 Laboratory Testing

Due to the sandy nature of the subsurface profile, laboratory testing was not required for
this investigation. The nature of the soils was measured by field testing only.

5.0 GEOTECHNICAL MODEL

5.1 Subsurface Profile

The subsurface profile encountered in the two deep drilled boreholes consisted of fine to
medium grained sand inferred to be deposited as a beach ridge dune. The consistency of
the sand was seen to be medium dense sands for the upper 3.5 to 3.8 meters overlying
dense to very dense indurated sand. Dense to very dense sand was encountered at
depths of 5.7m and 6.3m beneath the indurated sands,.

The hand auger boreholes encountered similar fine to medium grained sand, but with
some gravelly sand fill material to a depth of 0.85m in borehole HA3. Dynamic cone
penetrometer soundings indicate medium dense sand conditions to depths of between
4.8m and 4.9m and becoming dense below this level.

A summary of the subsurface profile is presented in Table 1 with detailed borelogs
included in Appendix B.
