Attachment B - Soil test report

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 calculated the following Ys value for the soil profile:

                                                   Ys = 20-30 mm

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
