33522 soil report SCG 28050(S) · MCU18/0001

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:

         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 17/04/2018 we have classified this site in
accordance with AS 2870-2011 as:

                                                   Class         S

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:

                             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

3     SITE DESCRIPTION

The construction area has a gradient in the order of 5%.

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

Trees are located adjacent the proposed construction site.

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