1 INTRODUCTION

Slingo Earthmoving commissioned Geotechnical Testing Services (GTS) to undertake a Level 1 Supervision (AS3798-2007) of the earthworks for the lot fill at McIvor Forest Estate Stage 14A, Junortoun. 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 on Lots 1 to 3 and 12.

The depth of fill across the lots varied from 300mm to 1000mm. Generally where the depth of fill is less than 300mm, it was placed as uncontrolled with no testing or supervision conducted.

A plan showing the test locations and fill depths is included in the Appendix.

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 building pads 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) as such a minimum of 1 test per 500m3, 1 test per 2500m2 or 3 tests per visit is required. The frequency of testing conducted was 1 test per residential lot per layer which exceeds minimum requirements.

15C 0564 Report 4

3 INSPECTION AND TESTING

Inspection of the excavated base was conducted by a Geotechnical Engineer and it was observed that the unsuitable material (vegetation and top soil/silt) had been removed with the base consisting of a 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. It is noted that for the stabilised sand, compaction testing is not required.

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.

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 3 and 12. 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.
