       in accordance with Australian Standard 2870 - 2011, 'Residential Slabs and Footings,
       Construction'.

       The Target Stratum for the foundation of the structure at locations BH1 & BH2 is the
       SAND at a depth of 1900mm (min.150kPa) below existing ground level.
       The Target Stratum for the foundation of the structure at location BH3 is the SAND at a
       depth of 1800mm (min.150kPa) below existing ground level.

       It is the designing engineer’s responsibility to address the potential influence of any trees
       present on or around the proposed building site.

       If any further fill is placed over the existing ground, the structure shall be piered through
       the fill into the existing material. Further note that the placement of reactive material as
       fill or cutting of the site may change the site’s classification.

       PLEASE NOTE: This report does not address slope stability. If a slope stability analysis
       is required, the services of a suitably qualified geotechnical engineer should be sought.

   4. SOIL PROFILE
      Refer to Soil Profile Report for borelog information

       Whilst every effort has been made to ensure that the borelogs carried out at the subject allotment
       are indicative of the soil profile over the site any discrepancy between the profile detailed in
       the borelogs and that observed during construction shall be referred to Global Testing for
       immediate attention.

   5. MATERIALS LABORATORY TEST RESULTS
      Soil Laboratory testing was not carried out on samples of the soil taken from the site because
      the clay content of the material was too low for Shrink-Swell movements to be critical in the
      classification of the soil profile. Determination of the classification for the site in this situation
      is based upon results from Dynamic Cone Penetrometer testing performed over the site.

       Please note that the Plasticity Index (PI) determined by the Atterberg Test may be correlated to
       an Instability Index (Ips)with reference to the results of extensive testing carried out by others,
       notably, Dr P Mitchell, ‘Footings for Small Scale Domestic Structures,’ March 1990.
