Dear Stephen

Asbestos Clearance InspectionArden Anglican School, 50 Oxford Street, Epping NSW

1. Introduction

Douglas Partners Pty Ltd (DP) was engaged by Lipman Pty Ltd (Lipman) to undertake a visualclearance inspection after asbestos removal work in a Nominated Work Area (NWA) at ArdenAnglican School, 50 Oxford Street, Epping NSW. The asbestos removal work comprised removal of~320 m3 of fill containing non-friable fragments of asbestos cement. This report outlines the results ofthe visual clearance inspection conducted on 17 November 2017 along with associated air monitoringresults.

2. Area Inspected

The Area Inspected comprised safely accessible exposed ground surfaces within the NWA (~400m2)that lie within the boundary fence lines of the current Construction Site (refer to Drawing 1 attached).It excludes all material(s) below the exposed ground surface.

3. Results

At completion of the visual clearance inspection the assessor found no visible asbestos residue fromasbestos removal work in the area, or in the vicinity of the area, where the work was carried out. The‘vicinity of the area, where the work was carried out’ comprises the decontamination area, loadingarea and truck route. A photographic record collected during the clearance inspection is provided inthe attached Plates.

This clearance report is only in relation to the NWA and no assessment has been undertaken onmaterial(s) that lie outside the NWA as these materials were outside the scope of works.

Control and clearance air monitoring for airborne asbestos fibres was conducted on 16 and 17November 2017 respectively. The air monitoring was conducted in accordance with the NationalOccupational Health and Safety Commission (NOHSC) Guidance Note on the Membrane Filter

Method for Estimating Airborne Asbestos Fibres, 2nd Edition, [NOHSC:3003(2005)]. All resultsobtained from the air monitoring were <0.01 f/mL which is the lower reporting limit of the method used.A copy of the laboratory certificates of analysis are attached to this report.

4. Recommendations

If asbestos or asbestos containing material (ACM) is encountered during future work at the site thenwork in the area should cease and access to the material should be suitably restricted. Asbestos mustbe managed in accordance with the requirements of the NSW Work Health and Safety Regulation2017 and subordinate codes of practice, standards and guidelines pertaining to asbestos. Thisincludes:

SafeWork NSW Code of Practice, How to Manage and Control Asbestos in the Workplace,September 2016; and

SafeWork NSW Code of Practice, How to Safely Remove Asbestos, September 2016.

5. Limitations

This report is provided for the exclusive use of Lipman for this project only and for the purposes asdescribed in the report. It should not be used by or relied upon for other projects or purposes on thesame or other site or by a third party. Any party so relying upon this report beyond its exclusive useand purpose as stated above, and without the express written consent of DP, does so entirely at itsown risk and without recourse to DP for any loss or damage. In preparing this report DP hasnecessarily relied upon information provided by the client and / or their agents.

The results provided in the report are indicative of the conditions on the site only at the specificlocations inspected and/or sampled/tested. While work is undertaken in a professional manner thenature of the contaminant and limitations of the method(s) used mean that we cannot guarantee thatall asbestos or ACM has been identified.

Inspections are limited to areas that are safely accessible at the time of the inspection and excludehidden and inaccessible locations such as within stockpiles and below the exposed ground surface.Any disturbance of the surface(s) inspected may result in the exposure of additional asbestos or ACMthat is outside the scope the visual inspection and sampling conducted.

DP’s advice is based upon the conditions encountered during this investigation. The accuracy of theadvice provided by DP in this report may be affected by undetected variations in conditions across thesite between and beyond the inspection, sampling and/or testing locations. The advice may also belimited by budget constraints imposed by others or by site accessibility.

This report must be read in conjunction with all of the attached and should be kept in its entiretywithout separation of individual pages or sections. DP cannot be held responsible for interpretationsor conclusions made by others unless they are supported by an expressed statement, interpretation,outcome or conclusion stated in this report.

Introduction These notes have been provided to amplify DP's report in regard to classification methods, field procedures and the comments section. Not all are necessarily relevant to all reports. DP's reports are based on information gained from limited subsurface excavations and sampling, supplemented by knowledge of local geology and experience. For this reason, they must be regarded as interpretive rather than factual documents, limited to some extent by the scope of information on which they rely. Copyright This report is the property of Douglas Partners Pty Ltd. The report may only be used for the purpose for which it was commissioned and in accordance with the Conditions of Engagement for the commission supplied at the time of proposal. Unauthorised use of this report in any form whatsoever is prohibited. Borehole and Test Pit Logs The borehole and test pit logs presented in this report are an engineering and/or geological interpretation of the subsurface conditions, and their reliability will depend to some extent on frequency of sampling and the method of drilling or excavation. Ideally, continuous undisturbed sampling or core drilling will provide the most reliable assessment, but this is not always practicable or possible to justify on economic grounds. In any case the boreholes and test pits represent only a very small sample of the total subsurface profile. Interpretation of the information and its application to design and construction should therefore take into account the spacing of boreholes or pits, the frequency of sampling, and the possibility of other than 'straight line' variations between the test locations. Groundwater Where groundwater levels are measured in boreholes there are several potential problems, namely: • In low permeability soils groundwater may

enter the hole very slowly or perhaps not at all during the time the hole is left open;

• A localised, perched water table may lead to an erroneous indication of the true water table;

• Water table levels will vary from time to time with seasons or recent weather changes. They may not be the same at the time of construction as are indicated in the report; and

• The use of water or mud as a drilling fluid will mask any groundwater inflow. Water has to be blown out of the hole and drilling mud must first be washed out of the hole if water measurements are to be made.

More reliable measurements can be made by installing standpipes which are read at intervals over several days, or perhaps weeks for low permeability soils. Piezometers, sealed in a particular stratum, may be advisable in low permeability soils or where there may be interference from a perched water table. Reports The report has been prepared by qualified personnel, is based on the information obtained from field and laboratory testing, and has been undertaken to current engineering standards of interpretation and analysis. Where the report has been prepared for a specific design proposal, the information and interpretation may not be relevant if the design proposal is changed. If this happens, DP will be pleased to review the report and the sufficiency of the investigation work. Every care is taken with the report as it relates to interpretation of subsurface conditions, discussion of geotechnical and environmental aspects, and recommendations or suggestions for design and construction. However, DP cannot always anticipate or assume responsibility for: • Unexpected variations in ground conditions.

The potential for this will depend partly on borehole or pit spacing and sampling frequency;

• Changes in policy or interpretations of policy by statutory authorities; or

• The actions of contractors responding to commercial pressures.

If these occur, DP will be pleased to assist with investigations or advice to resolve the matter.

Site Anomalies In the event that conditions encountered on site during construction appear to vary from those which were expected from the information contained in the report, DP requests that it be immediately notified. Most problems are much more readily resolved when conditions are exposed rather than at some later stage, well after the event. Information for Contractual Purposes Where information obtained from this report is provided for tendering purposes, it is recommended that all information, including the written report and discussion, be made available. In circumstances where the discussion or comments section is not relevant to the contractual situation, it may be appropriate to prepare a specially edited document. DP would be pleased to assist in this regard and/or to make additional report copies available for contract purposes at a nominal charge. Site Inspection The company will always be pleased to provide engineering inspection services for geotechnical and environmental aspects of work to which this report is related. This could range from a site visit to confirm that conditions exposed are as expected, to full time engineering presence on site.
