Slope Stability Report

       The Target Stratum for the foundation of the structure is the SILTY SAND at a depth of
       1000mm 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 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.

   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.

                  PREDICTED SURFACE MOVEMENT                                  N/a

       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.

       Yours Sincerely,




MICHAEL PINKNEY. (Laboratory Manager)
