7.0 Site Class Report (Proposed Residence)

       in accordance with Australian Standard 2870 - 2011, 'Residential Slabs and Footings,
       Construction'.
       The Target Stratum for the foundation of the structure located at BH11 is the SANDY
       CLAY (Becoming Extremely Weathered Rock) at a depth of 1000mm below existing
       ground level.
       The Target Stratum for the foundation of the structure located at BH12 is the SANDY
       CLAY (Becoming Extremely Weathered Rock) at a depth of 1200mm 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 carried out on samples of the soil taken from the site gave the
       following results:
                BOREHOLE                                           BH11
                DEPTH RANGE OF SAMPLE                          200-400mm
                LIQUID LIMIT (%)                                    N/a
                PLASTIC LIMIT (%)                                   N/a
                PLASTIC INDEX (%)                                   N/a
                LINEAR SHRINKAGE (%)                                N/a
                INSTABILITY INDEX (%)                               N/a
                SHRINK SWELL INDEX, Iss (%)                         2.1
                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)
