MCU14/0024 - Response to Information Request - Attachment 4

1 INTRODUCTION

SCG Consulting Engineers has performed a site classification in accordance with AS 2870-2011 and made
recommendations based upon the ciassification for a buiiding to be constructed ai 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 Timber/Masonry
Ground Floor Slab on Ground
Upper Fioor Suspended Slab
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 06/01/2014 we have classified this site in

accordance with AS 2870-2011 as:
[_ ClassP |

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
