GLOBAL TESTING THE ONLY NAME IN SOILS QBCC Licence No. 1018403 PH: 07 54 740 900 3/53 Gateway Drive, Noosaville 4566 Email: [email protected] | 20/0611-2__ SITE CLASSIFICATION REPORT | LYNDALL PETERSEN. PROPOSED SUBDIVISION & PROPOSED FUTURE RESIDENCE, PROPOSED LOT 11 (No.130) LAKE MACDONALD DRIVE, COOROY. E | 11/06/2021 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 recommended for the structure so as to allow adequate performance of the footings under the soil conditions determined at the site. 2. SITE DESCRIPTION Type of Allotment Residential Vegetation (Building Envelope) Grassed Vegetation (Allotment) Grassed, scattered undergrowth, scattered large trees. Road Status Sealed Slope 22% Towards the West Surface Water will Drain Towards West Will Surface Water from adjoining Yes allotments traverse this site? Does the site have any watercourses Yes-Dam downhill. Surrounding Allotments Left Acreage Right Acreage Rear Acreage Depth to Weathered Rock 4.0m (BH6 & BH7) Depth to Water Table 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 poor bearing capacity-See Target Stratum). (Please note: If not for the poor bearing capacity, this site has the characteristics of an ‘M?’ site) in accordance with Australian Standard 2870 - 2011, 'Residential Slabs and Footings, Construction’. The Target Stratum for the foundation of the structure located at BH6 is the SILTY SANDY CLAY at a depth of 1200mm below existing ground level.

The Target Stratum for the foundation of the structure located at BH7 is the SILTY SANDY CLAY at a depth of 1200mm below existing ground level. 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. PLEASE NOTE: This report does not address slope stability. If a slope stability analysis is required, the services of a suitably qualified geotechnical engineer should be sought. 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 BH6 DEPTH RANGE OF SAMPLE 300-600mm LIQUID LIMIT (%) NE PLASTIC LIMIT (%) N/a PLASTIC INDEX (%) Nia LINEAR SHRINKAGE (%) N/a INSTABILITY INDEX (%) Nia SHRINK SWELL INDEX, Iss (%) 2.6 PREDICTED SURFACE MOVEMENT Nia 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, f i MICHAEL PINKNEY. (Laboratory Manager) Page | 2 Borelogging in accordance with AS1726-2017 Geotechnical Site Investigations Code 21/0611-2

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 additional 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 representative 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 approximate 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 system. 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.
