1     INTRODUCTION

SCG Consulting Engineers has performed a limited site investigation and established a site classification in
accordance with AS 2870-2011 and made recommendations based upon the classification for a building to be
constructed at the above site. This report does not include an assessment of Slope Stability, Landslide Risk, or
specifications for damp proofing, termite protection or moisture barriers.

This soil test and footing report relates only to the above property and the proposed construction as described
below:

                        Proposed Construction                         Residential Dwelling
                            External Walls                                Block/Timber
                            Internal Walls                                   Timber
                            Ground Floor                           Slab on Ground/Suspended
                             Upper Floor                                     Timber
                           Building Platform                               Cut Fill Pad
                         Masonry Articulation                       Required @ 8 m centres


             This report must be read and considered as a whole. All of our recommendations,
             foundation plans, sections and appendices must be read, considered and followed by all
             people involved in this project including the client to ensure adequate long term performance
             of the footing system constructed on this site. A copy of this report must remain with the
             client or final owner of the building upon completion of the proposed works. If you are
             unsure of any of the requirements herein, you must seek clarification from this office.


2     SITE CLASSIFICATION

After considering the results of our field investigation performed on 08/09/2015 we have classified this site in
accordance with AS 2870-2011 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 and poor bearing capacity encountered during our testing on
site. Please refer to our definitions list appended to this report for further descriptions of these characteristics.

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

The site preparation details that follow have allowed for the influence of the earthworks described in section 5.0
below.

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                    H1      High-1
                               Ys = 60 – 75mm                     H2      High-2
                               Ys = > 75mm                        E       Extreme
