1 INTRODUCTION A & B Earthmoving commissioned Geotechnical Testing Services (GTS) to undertake Level 1 Supervision and testing (AS3798-2007) for the earthworks at Argyle Estate on Sullivan Street, Ascot. Level 1 Testing was generally performed in line with AS3798-2007 “Guidelines on Earthworks for Commercial and Residential Development” and provides inspection of the construction of controlled fill and compaction testing in accordance with AS1289 “Methods of Testing Soils for Engineering Purposes”. The Level 1 testing was undertaken by Geotechnicians with supervision provided by a Geotechnical Engineer from GTS. 2 SCOPE OF WORKS 2.1 AREA OF WORK Geotechnical Testing Services provided Level 1 inspection and testing of the engineered fill placed across Lots 1 to 13. The depth of fill across the site varied from less than 300mm to around 0.8 metres in the with the approximate locations shown on the attached site plan. It is noted that the sites with 300mm or less of fill were not included in the inspection and testing. 2.2 PLACEMENT SPECIFICATION Whilst there was no earthworks specification compiled for this project, the placement of the fill and associated works generally followed the recommendations outlined in AS3798-2007 “Guidelines for Earthworks for Commercial and Residential Developments” and the construction specification. In summary, the earthworks comply with the following: • The layers for residential lots are to be compacted to at least 95% of the density ratio in accordance with AS1289 5.1.1 (or 5.7.1), based on Standard compaction. In accordance with Table 8.1 of AS3798-2007, the site would be considered large scale (greater than 1500m2) and therefore a minimum of 1 test per 2500m2 or 3 tests per visit are required. It is noted that based on the size of the earthworks, that 1 test per lot is not required, however, all lots were tested at some stage through the filling process.
Geotechnical Testing Services (Southern) Report: 17C 0543 Report.docx Page 5
3 INSPECTION AND TESTING Inspection of the excavated bases were conducted by a Senior Geotechnical Engineer and it was observed that the unsuitable material (vegetation, top soil/silt) had been removed with the base consisting of a Sandy Silty Clay material of good strength. Level 1 inspection and testing was undertaken by a geotechnician from GTS who nominated the timing and location of the in-situ density tests. The approximate location of each test is recorded on the test reports and attached fill plan. Laboratory compaction testing was undertaken on a one to one basis at our Bendigo laboratory. A summary of the results of the compaction control testing is presented in a table below with the full NATA endorsed test reports included in the Appendix. 4 SUMMARY OF TEST RESULTS A summary of the test results is included in the following table with full NATA accredited reports included in the Appendix.

5 STATEMENT OF COMPLIANCE GTS personnel have provided Level 1 inspection and testing services during the placement of material for the filling of Lots 1 to 13. The placement of fill and construction techniques adopted was observed throughout the project. Based on observations made by GTS personnel and the results of field and laboratory tests, we consider that the fill has been placed and compacted and is considered to be engineered or controlled fill. Therefore, subject to residential site classifications, the controlled fill material is deemed a suitable founding medium for future residential buildings. It is noted that top soil material may be spread across the sites following completion of these earthworks and that this top soil material is not considered controlled fill.
