soil test

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                                 Masonry
                          Internal Walls                             Masonry/Timber
                          Ground Floor                               Slab on Ground
                           Upper Floor                             Suspended Concrete
                         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 05/12/2022 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
