Slope Stability Report (rec. 16.04.25) · MCU25/0042

4.0        FINDINGS:

The soil profiles encountered are shown on the attached borelog sections.

No water table was encountered during our testing program.

The sandy soils encountered are susceptible to collapse when unconfined. This may effect excavations and result
in additional earthworks and increased concrete volumes. Temporary shoring or Forma-Tube may be required to
retain the sands prior to concreting.

The samples classified on-site were assessed as having negligible plasticity, therefore laboratory testing was
considered unnecessary.

We have assessed the expected differential movement of the soil profiles encountered to be the equivalent of a site
with a Ys of less than 20mm.

Fill, which we have described as uncontrolled was encountered to the following depths

                                       Test Site 1 - 500 mm        Test Site 2 - 400mm

At the time of writing this report we were unable to describe the fill as controlled. This can be revised if documentation
is available indicating that this fill has been compacted and certified in accordance with AS 3798-2007.



The following foundation material will provide a safe bearing capacity (100 kPa) for buildings within the scope of AS
2870-2011.

                FOUNDATION MATERIAL - NATURAL MEDIUM DENSE SILTY SAND

We strongly recommend that any footing design for this allotment be carried out by a suitably qualified
person in accordance with AS2870-2011.

Where site drainage and landscaping does not conform to the specifications of AS 2870-2011 and CSIRO
Information Service Sheet BTF-18 (2003) damage to the building can be expected. A single copy of this
document is issued with the original issue of this report. Please consult your builder or contact this office
