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                          Industrial Building
                           External Walls                                 Concrete

         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 25/10/2016 we have classified this site in
accordance with AS 2870-2011 as:

                                                    Class H1

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 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:

                               Ys = > 75mm                      E         Extreme

3     SITE DESCRIPTION

The construction area has a gradient in the order of 3%.

Vegetation on the construction area (and nearby surrounds) consists of grasses.

The existing surface drainage is fair and sub-surface drainage is poor.
