3018 AppendixD

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.

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 BH1
DEPTH RANGE OF SAMPLE 0.2-0.5m
LIQUID LIMIT (%) N/a
PLASTIC LIMIT (%) Nia
PLASTIC INDEX (%) N/a
LINEAR SHRINKAGE (%) Nia
INSTABILITY INDEX (%) N/a
SHRINK SWELL INDEX, Iss (%) 2.8
PREDICTED SURFACE MOVEMENT 35mm

 

 

 

 

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,
