1. Introduction

This report presents the results of the Level 1 Inspection and Testing for fill placement within the

Stage 106 of the Warralily Estate Armstrong Creek Development, undertaken by Coffey Services

Australia Pty Ltd (Coffey).

The works were commissioned by Martin O’Hanlon of Newland Developers Pty Ltd (Newland).

2. Project Summery

We understand that Newland requires fill placement within Stage 106 of the Warralily Armstrong Creek Development in the area as shown in Figure 1, to be constructed under Level 1 Inspection and Testing undertaken by a Geotechnical Inspection and Testing Authority (GITA).

Level 1 Inspection and Testing, as defined in AS3798-2007 “Guidelines on Earthworks for Commercial and Residential Development,” provides for full time inspection of the construction of controlled fill and field and laboratory testing in accordance with AS1289 “Methods of Testing Soils for Engineering Purposes.”

The Level 1 Inspection for Stage 106 was undertaken by geotechnical professionals from Coffey over the period of several months as shown in Table 1.

2.2. Excluded areas

This report does not include fill other than where mentioned in this report or any other fill that may be placed during this period or subsequent periods at or surrounding the subject site. Excluded works comprise road construction, trench backfill, foot paths, landscaping fill and placement of topsoil.

3. Specifications/work instructions

The specification for the project was prepared by SMEC Australia Pty Ltd (SMEC) for Armstrong

Creek Development Corporation Pty Ltd under reference number 0557ESB-24. An extract of the

specification was provided to Coffey in an email sent by Shane McGlynn from SMEC on 5 October

2012. The extract from the specification forwarded to Coffey is provided in Appendix C and a short

summary is provided below:

- All filling in excess of 200mm depth within the building envelope of allotments shall be

undertaken to specifications satisfying the requirements of AS 3798-2007 “Guidelines on

Earthworks for Commercial and Residential Development”;

- All such filling works shall be undertaken with supervision to the standard detailed as “Level 1

Inspection and Testing” in AS 3798-2007, such that the supervisor will issue a notice detailing

that the works comply with the specifications and drawings;

- Material to be used for fill construction shall satisfy the requirements of AS 3798-2007;

- Fill to be compacted in near horizontal layers not exceeding 300mm loose thickness;

- Compaction to achieve a dry density ratio of at least 95% Standard; and

- Moisture content of the fill material is to be within ±3% of the Standard Optimum Moisture

Content (SOMC).

4. Fill Material

Fill used for the construction of Stage 106 comprised locally sourced clay from the existing stages

within the Armstrong Creek Development. Any observed organic or deleterious matter including any

oversize particles was removed during the fill placement within the engineered fill platforms.

5. Earthworks

The earthworks for this project included the following:

• Stripping of topsoil,

• Stripping of uncontrolled fill from base of a creek running though the site,

• Assessment, remediation and proof rolling of subgrade, and;

• Placement and compaction of fill to construct the engineered fill areas.

5.1. Subgrade assessment

The subgrade for Stage 106 was assessed progressively throughout the works in four sections as follows:

- The base of the existing creek that was running from west to east through the western pad was assessed on 16 and 17 April 2018;

- The western pad subgrade, to the south of the existing creek, was assessed on 5 May 2018. The area to the north of the creek was assessed on 14 June 2018.

- The base of the existing creek that was running from west to east through the eastern pad was assessed on 16 and 17 May 2019;

- The eastern pad subgrade, to the south of the existing creek, was assessed on 09 July 2019. The area to the north of the creek was assessed on 10 July 2019.

Subgrade assessment was conducted following the removal of topsoil, uncontrolled fill and some fill stockpiles that were present at the site, and before any fill was placed. In all areas the subgrade comprised natural clay. No soft spots were observed during the subgrade proof rolling. A surveyor engaged by Winslow undertook a survey of the subgrade levels following Coffey’s assessment.

5.2. Fill Construction

All sourced fill was trucked in, spread with a bulldozer and compactor and compacted with a

compactor. A water cart and compaction plant were present onsite during works for moisture

conditioning and compaction.

Coffey personnel were on site on a full time basis during the placement, compaction and testing of the fill on the dates noted in Section 2 of this report.

5.3. Survey data and fill thickness

Winslow’s appointed surveyor Survey Management Solutions (SMS) conducted a survey of the

subgrade level of the fill areas of Stage 106, following the topsoil removal, progressively throughout the

works. The fill was also surveyed following the completion of the earthworks, before the placement of

the topsoil.

The initial existing surface levels and final levels were provided by SMS on drawing “Warralily Stage

106 Fill Plan” dated 26 April 2019 (attached in Appendix B).

The information from above surveys has been summarised in Table 3.

5.3.1. Eastern pad including Creek area

Based on the survey data, the fill thickness within the Eastern Pad ranged between 0.38m to 0.79m, except for the creek backfill areas where the fill thickness should be exceeding 1m (these levels are not shown on the survey drawings). Coffey have observed up to 7 layers of fill being constructed within most parts of the Eastern Pad area, and up to 5 layers within the creek backfill. Based on the survey data and the number of layers placed in these areas, the fill thickness is generally compliant with the project specifications.

5.3.2. Western pad including Creek area

Based on the survey data, the fill thickness within the Western Pad ranged between 0.20m to 0.79m, except for the creek backfill areas where the fill thickness should be exceeding 1m (these levels are not shown on the survey drawings). Coffey has observed up to 3 layers of fill being constructed within most parts of the Eastern Pad area, and up to 5 layers within the creek backfill. Based on the survey data and the number of layers placed in these areas, the fill thickness is generally compliant with the project specifications.

6. Testing & Results

Field density testing was undertaken progressively during construction on the compacted fill. Testing

was undertaken under the frequencies listed below, subject to the area and volume worked on the

day of testing:

- 1 test per material type per layer per 2500m2 or 1 test per 500m3 distributed reasonably

evenly or 3 tests per lot – whichever requires the most tests in accordance with Type 1

Earthworks (large scale operations) as defined in Table 8.1 of the AS 3798-2007;

- 1 test per layer per 1,000m² or 1 test per 200m³ distributed reasonably evenly or 1 test per

residential lot - whichever requires the most tests in accordance with Type 2 Earthworks

(small scale operations) as defined in Table 8.1 of the AS 3798-2007;

- 1 test per layer per 500m² or 1 test per 100m³ distributed reasonably evenly or 3 tests per visit

- whichever requires the most tests in accordance with Type 3 Earthworks (concentrated

scale operations) as defined in Table 8.1 of the AS 3798-2007;

Level 1 Inspection and Testing, Stage 106, Warralily Armstrong Creek Development

Coffey

- 1 test per 2 layers per 50m² distributed reasonably evenly throughout the fill depth –in

accordance with Type 4 Earthworks (confined operations) as defined in Table 8.1 of the AS

3798-2007.

The field density testing was conducted by Coffey’s personnel on site using a Nuclear Density Gauge

in accordance with AS1289.5.8.1 ‘Determination of field density and field moisture content of a soil

using a nuclear surface Moisture – Density Gauge’.

The laboratory testing was performed at Coffey’s laboratory and Ground Science Laboratory. A Hilf

Rapid compaction test was performed for each field density test in accordance with AS1289.5.7.1

‘Soil compaction and density tests—Compaction control test—Hilf density ratio and Hilf moisture

variation (rapid method)’.

The location of the field density tests was determined by use of the GPS on the construction plant

operated by the contractor on site. For each of the field density tests, the following items were

recorded on the field sheets: test location, layer number, layer thickness, test depth, soil type, time

and date of testing.

A total of 48 density tests were performed during the earthworks in the locations as presented in

Figures 2. Of the 48 tests, 2 did not meet the specified criteria. These areas were subsequently re-

worked and re-tested. Once re-tested, the 2 test results met the specified dry density ratio criteria of

95% Standard compactive effort and moisture variation of ±3% of the Optimum Moisture Content

(OMC).

A summary of the test results obtained from the field density testing within Stage 106 are provided in a table presented as Figure 3. The laboratory test reports of the field density tests are presented in Appendix A.

7. Statement of compliance

Coffey personnel have provided Level 1 inspection and testing services during the construction of the engineered fill areas within Stage 106 as shown in SMS survey drawing in Appendix B. A geotechnical professional from Coffey (Level 1 Inspector) was on site on a full time basis during the construction of the engineered fill platforms and observed the construction techniques adopted for the dates noted in section 2 of this report.

Based on observations made by Coffey’s Level 1 Inspector and the results of field and laboratory tests, Coffey consider that the engineered fill areas within Stage 106 as indicated in the SMS survey drawing in Appendix B, constructed by Winslow to the levels indicated in Section 5.3 of this report, as far as we have been able to reasonably determine, have been placed in general accordance with the intent of the specification.
