Project 71723.08Barangaroo Delivery Authority 17 December 2010Level 6, 66 Harrington Street CF:jlbTHE ROCKS NSW 2000 Attention: Mr Brian ten Brinke Email: [email protected] Dear Sirs Factual Report – Pre Early Works Additional Environmental Assessment - Soils Barangaroo Headland Park 1. Introduction Douglas Partners Pty Ltd (DP) was engaged by the Barangaroo Delivery Authority to undertake additional environmental investigations, as required, at the proposed Headland Park site, located in the northern portion of the Barangaroo Redevelopment site. This factual report presents the findings of additional investigations requested by JBS Environmental Pty Ltd (JBS), in their Sampling, Analysis and Quality Plan – Pre-Early Works Additional Environmental Assessment document dated October 2010, report reference JBS41181-15745, Revision C (JBS SAQP). It is understood that no field or analytical result interpretation or analysis is required from DP. 2. Scope of Works The scope of works of the additional investigation, addressing the requirements of the JBS SAQP, was as follows:

• Obtaining services drawings for the site;

• Field location of underground services prior to drilling;

• Drilling at 31 locations specified by JBS, denoted as boreholes JBS300 to JBS330 (see attached Drawing 1);

• Boreholes were augered through fill materials and natural soils / bedrock and terminated in interpreted natural materials (soils or bedrock) as specified by JBS at each of the locations. Auger refusal was encountered within the filling during the drilling of several of the bores, usually on crushed sandstone boulders, ballast gravel, or anthropogenic material such as steel or

concrete. The bores were first moved (generally within one metre of the designated location) in an attempt to avoid the filling on which the refusal occurred. Where this was unsuccessful, alternative drilling techniques were employed, including rotary or casing advancer (using fresh water) and air hammer (ODEX) drilling. The relocated bores are also indicated on Drawing 1;

• Samples were collected at generally 1 m depth intervals (where possible) at each of the boreholes, as well as additional depths specified by JBS in accordance with Table 6.1 of the JBS SAQP;

• Field quality assurance and quality control procedures were carried out in accordance with the programme detailed in Table 6.2 of the JBS SAQP;

• Screening of all recovered samples using a field portable photo-ionisation detector (PID). It is noted that due to limited sample retrieved in several locations (generally below the water table), some samples were not screened;

• Dispatch of selected samples to NATA accredited laboratories for quantitative analysis for the analytes as detailed in Table 6.1 of the JBS SAQP;

• Store remaining soil samples not analysed at the laboratory for potential future analysis; and

• Preparation of this Factual Report. 3. Site Observations Drilling was undertaken between 18 November to 2 December 2010 using various truck-mounted and bobcat-mounted drill rigs. Details of the sub-surface conditions encountered during the course of the investigation are included in the attached borehole logs (JBS300 to JBS330, and relocated bores labelled “A”, “B” and “C”). The bore locations are shown on Drawing 1. Signs of visual and/or olfactory contamination as well as groundwater strike were noted in the borehole logs. Two additional groundwater monitoring wells were installed as part of this investigation at bores JBS322A and JBS328, as per the SAQP. Groundwater sampling and analysis of these wells and several existing wells (as required under the SAQP) was also carried out and is reported separately. 4. Analytical Results Soil samples were submitted to the primary laboratory (Envirolab) after completion of drilling works. Inter-laboratory samples (duplicated for QA/QC purposes) were separately submitted to the secondary laboratory (LabMark). Table 1 below shows the replicate samples corresponding to their original samples.

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.

July 2010

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.
