JOB NUMBER 23-1028 SITE CLASSIFICATION REPORT
CLIENT THE SHED HOUSE
SITE LOCATION PROPOSED DWELLING
19 HAPPY JACK CREEK ROAD, RIDGEWOOD QLD AUSTRAILIA
REPORT DATE 13/09/2023
1. INTRODUCTION
The purpose of this report is to classify the subject allotment in accordance with Australian Standard
2870 - 2011 'Residential Slabs and Footings'. From this classification, a footing system can be recom-
mended for the structure so as to allow adequate performance of the footings under the soil conditions
determined at the site.
Trees: There are medium (5-10m) trees at this site. Global Testing recommends an experienced ar-
borist be commissioned to quantify the existing size, location, predicted maximum height and type of
these trees to aid in the design process. It is the responsibility of the designing engineer to apply the
principals of AS2870-2011 Appendix H 'Guide to Design of Footings for Trees'. The classification
herein excludes the effect of trees on the site.
2. SITE DESCRIPTION
Type of Allotment Acreage
Vegetation Grassed
Slope 5-30% to South
Surface Water will Drain Towards West
Will Surface Water from adjoining Yes
allotments traverse this site?
Surrounding Allotments
Left Acreage
Right Acreage
Rear Acreage
Depth to Weathered Rock BH1 (2.5m), BH2 (1.9m)
Depth to Water Table BH1 (N/a), BH2 (N/a)
3. SITE CLASSIFICATION AND TARGET STRATA
Based on the findings of the site investigation, the classification of the site is considered to conform to:
CLASS “P” – (Due to the Presence of Trees and Poor Bearing Capacity -
See Target Stratum)
PLEASE NOTE: If not for the above reasons, this site would have the characteristics of a Class M Site in regard
to surface movement values) ie. <40mm for ys)
If earthworks are proposed, the classification would increase significantly to approximately 70 mm for ys
in accordance with Australian Standard 2870 - 2011, 'Residential Slabs and Footings, Construction'.
The target stratum for the foundation of the structure located at BH1 is to be determined by the
designing engineer.
The target stratum for the foundation of the structure located at BH2 is to be determined by the
designing engineer.

PLEASE NOTE: This report does not address slope stability. If a slope stability analysis is re-
quired, the services of a suitably qualified geotechnical engineer should be sought. We can rec-
ommend one or organise this service on your behalf.
It is the designing engineer’s responsibility to address the potential influence of any trees present
on or around the proposed building site.
If any fill is placed over the existing ground, the structure shall be piered through the fill into the
existing material. Further note that the placement of reactive material as fill, or cutting of the
site may change the site’s classification.
4. SOIL PROFILE
Refer to Soil Profile Report for borelog information.
Whilst every effort has been made to ensure that the borelogs carried out at the subject allotment are
indicative of the soil profile over the site any discrepancy between the profile detailed in the borelogs
and that observed during construction shall be referred to Global Testing for immediate attention.
5. MATERIALS LABORATORY TEST RESULTS
Soil Laboratory testing carried out on samples of the soil taken from the site gave the following results:
BOREHOLE BH1
DEPTH RANGE OF SAMPLE 500-700mm
LIQUID LIMIT (%) N/a
PLASTIC LIMIT (%) N/a
PLASTIC INDEX (%) N/a
LINEAR SHRINKAGE (%) N/a
INSTABILITY INDEX (%) N/a
SHRINK SWELL INDEX, Iss (%) 3.7
PREDICTED SURFACE MOVEMENT 30-40mm
Please note that the Plasticity Index (PI) determined by the Atterberg Test may be correlated to an
Instability Index (Ips)with reference to the results of extensive testing carried out by others, notably, Dr
P Mitchell, ‘Footings for Small Scale Domestic Structures,’ March 1990.
Yours Sincerely,
(Luke Wade - Office Manager)

LIMITATIONS
Recommendations given in this report are based on the information supplied by the client regarding the
proposed building construction in conjunction with the findings of the investigation. Any change in
construction type, building location or omission in the client supplied information, may require addi-
tional testing and/or make the recommendations invalid.
The recommendations herein identify a target soil stratum into which the footings are to be founded.
The target stratum has been located by the depth in mm of the target stratum's upper horizon boundary
below the existing ground surface level at the time of the site investigation. Any cutting or filling works
and any surface erosion or deposits subsequent to the site investigation, will alter the measured location
of the stratum relative to the surface. Where required, the author should be notified in such cases to
confirm the location of the target stratum.
The description of the soil given in the Soil Profile section of this report is intended as a brief overview
of the soil's primary constituents. For a detailed classification of the soil, the reader should refer to the
Soil Profile Reports and/or Borehole Reports attached to this report.
Every reasonable effort has been made to locate the test sites so that the borehole profiles are repre-
sentative of the soil conditions within the area investigated. The client should be made aware however,
that exploration is limited by time available and economic restraints. In some cases, soil conditions can
change dramatically over short distances, therefore, even careful exploration programs may not locate
all the variations.
If soil conditions different from those shown in this report are encountered or are inferred from other
sources, then the author must be notified immediately.
This report may not be reproduced except in full. The information and drawings provided with this
report shall only be used and will only be applicable for the development shown on the client supplied
information provided for this site.
Any dimensions, contours, slope directions and magnitudes shown on the Test Locality Plan shall not
be used for any building construction or costing calculations. The purpose of the plan is to show ap-
proximate location of field tests only.
Any changes made to these recommendations by persons unauthorised by the author will legally be
interpreted as that person assuming the responsibility for the long-term performance of the footing sys-
tem.
The recommendations contained in this report have not taken into consideration the long-term effects
of any previous, current or potential subsurface work by mining companies or potential slope instability
problems. At the time of writing this report neither our client (nor his agent) nor the local authority had
made the author aware that these problems may be affecting this allotment. If a mining subsidence or
slope stability assessment is required for this allotment, the recommendations of a suitably qualified
geotechnical engineer should be sought.
