1 Introduction Chadwick Geotechnics Pty Ltd (Chadwick Geotechnics) was engaged by National Pacific Properties Wynnstay Pty Ltd C/o Beveridge Williams Pty Ltd, to provide Level 1 Inspection and Testing services for the earthworks within parts of Stage 7.

2 Project details The project included the preparation and filling of lot’s 705, 708, 709, 718, 730 and 734 to 739 at the site. The specification required the earthworks to be completed under Level 1 Supervision, that is full-time Supervision and Testing of the earthworks. Chadwick Geotechnics were onsite for the duration of the earthworks program. The location of the site is shown in figure 1 below.

Figure 1: Approximate site location (Image sourced from Nearmaps)

3 Geology Published information shows the site to be underlain by the Baxter Sandstone formation (Nxx) comprising Non-Marine Fluvial, sandstone, conglomerate siltstone and ironstone.

4 Specification A summary of the specification is shown below:

5 Inspection and testing The inspection and testing of earthworks has been carried out in accordance with AS3798-2007, ‘Guidelines on earthworks for commercial and residential developments’, with a frequency of field density tests as per a type one project (large scale operation). Compaction control laboratory testing was undertaken in our NATA accredited Dandenong South laboratory in accordance with AS1289 ‘Methods of Testing Soils for Engineering Purposes’.

Prior to fill being placed the subgrade was inspected. The inspections were performed in accordance with the Level 1 guidelines presented in AS 3798–2007 Section 5.5. No soft spots were encountered during the inspections, and the area was found to be firm and free of vegetation and other deleterious material.

Full time Level 1 inspection and testing of the filling operations commenced on the 24th May 2017 and was completed on the 7th February 2017. During this period Chadwick Geotechnics observed the filling works including the supply of material, conditioning of material (moisture conditioning and oversize removal), placement and compaction of the fill.

All fill material was placed in lift sequences and the Chadwick Geotechnics verified that the surface of the stripped area and additional lifts were thoroughly scarified and moisture conditioned prior to placement of additional layers to prevent delamination at the layer interface.

Field density and moisture content testing was carried out using a calibrated nuclear density gauge in accordance with AS 1289.5.8.1. The HILF rapid compaction test was used for peak converted wet density determinations in accordance with AS 1289.5.7.1. Test locations were recorded using a handheld GPS unit. A site plan showing the field density test locations is provided in Appendix A.

A total of eighteen (18) tests were performed during the filling process.

The results show that three (3) tests failed to meet the specification requirements for the project. The earthworks contractor was advised of the tests that failed and the fill relevant to those areas was reworked, reconditioned, re-compacted and subsequently retested. The final results show the tests achieved the specification requirements for the project.

A summary table of Hilf density tests is provided in Appendix B and the laboratory test reports are provided in Appendix C.

6 Conclusion On the basis of our direct supervision and after considering all test results relating to the project, it is our opinion, so far as it is able to be determined, that:

The materials used by the earthworks contractor met the geotechnical property requirements of the specification.

The sourced fill was considered to be natural and clean and suitable for use at the site. The fill material placed was tested at a suitable frequency in accordance with AS 3798-2007-

Table 8.1 and the results indicate the compacted clay achieved the density requirement of the specification.

Given the consistent construction practices followed by the earthworks contractor and as witnessed by the Chadwick Geotechnics, combined with the satisfactory verification of test results achieved, it is inferred that areas of the site between test locations were performed to the same standard as those areas that have been tested.

It is our opinion that the earthworks undertaken have been performed in accordance with the requirements of Section 8.2 Level 1 Inspection and Testing AS3798-2007.

Appendix D: Controlled fill certificates

CONTROLLED FILL CERTIFICATE - LEVEL 1 INSPECTION & TESTING

SUMMARY

Chadwick Geotechnics Pty Ltd conducted Level 1 inspection and testing, in accordance with Section 8.2 Level 1 inspection and Testing AS3798-2007, Guidelines on earthworks for commercial and residential developments, during the filling of the site.

So far as it is able to be determined, the fill was placed in accordance with the Specification that required a minimum density ratio of 95% of HILF Density (AS1289.5.7.1) to be achieved.

LIMITATIONS

This Certificate has been commissioned for the filling of the area mentioned above. No responsibility or liability will be accepted for the use of this report for any purpose other than that for which Chadwick Geotechnics Pty Ltd was engaged, specifically for Level 1 Inspection and Testing of the structural fill (excluding top soil).

This report is based on the conditions present and factors affecting the soil at the time of inspection, namely the 24th May 2017 to the 7th February 2017. No responsibility or liability will be accepted and Chadwick Geotechnics Pty Ltd is indemnified to the full extent permitted by law in respect of the use of this Certificate where there has been a change in the nature of the project, or in the site conditions since the site testing.
