Attachment 3 Soil Test Report

1.0 INTRODUCTION:

This company has performed a site classification in accordance with AS 2870-2011 at the above
address. This site classification report does not include an assessment of Slope Stability or Landslide
Risk.
This report must be read and considered as a whole. All of our recommendations
and appendices attached must be read, considered and followed by all people
involved in this project including the client to ensure adequate long term
performance of a footing system constructed on this site. If you are unsure of any of
the requirements herein, you must seek clarification from this office.

2.0 SITE CLASSIFICATION:

After considering the results of our field investigation performed on 22/01/2014 we have classified this

site as:
[ Class P__|

The classification has been calculated from test work performed on the soil profile encountered on the
day of our fieldwork and consideration of AS2870-2011. Any disturbance of the soil profile may result
in a change to the classification.

The ‘P’ classification relates to the loose sands encountered during our testing on site. Please refer to
our definitions list appended to this report for further descriptions of these characteristics.

The abnormal moisture conditions are due to poor drainage within the allotment, the presence and
proximity of trees to the allotment and existing trees located on the proposed construction area that will
be removed.

With respect to potential surface movements through seasonal moisture variations, the site could be
considered equivalent to a class S site.

Site Classification: The site classification is calculated in accordance with the “AS2870-2011
Residential Slabs and Footings-Construction” and relates to the estimation of Ys, “The characteristic
surface movement’ within reactive soil profiles. The limits used for this classification are as follows:

 

 

 

 

 

 

 

 

[ Predicted Surface Movement __| Classification |
Ys = <=20mm s Slight
Ys = >20 — 40mm M Moderate
Ys = >40 - 60mm Hi High-1
Ys = 60 — 75mm H2 High-2
Ys => 75mm E Extreme

3.0 SITE DESCRIPTION:
The construction area has a gradient in the order of 16%.
Vegetation on the construction area (and nearby surrounds) consists of grasses and dense trees.

The existing surface drainage is good and sub-surface drainage is good.
