Attachment 3 - Construction Management Plan

                                                      Westcon Site Management Pty Ltd

          Where unexpected contamination is discovered as a result earthworks or excavation, the
          Director or Site Manager is to be informed immediately, and if required the local council
          or EPA is also notified. The activity in the area affected must cease until further
          instructions.

          The subcontracted agent is responsible for thoroughly washing down plant and equipment
          used in the excavation, removal and transport of contaminated materials on completion of
          operations and contaminated wash water disposed as appropriate.

          Any soil contamination, which may result from spills, loading of contaminated materials or
          handling of dangerous goods, must be cleaned or treated as soon as possible.

4.1.3 Acid Sulphate Soil (ASS)

          As appropriate, ASS may be either transported to an area set aside for treatment or returned
          to its original environment or disposed of to an authorised landfill. Material identified as
          acid sulphate is to be kept wet and/or covered in a suitable bunded area to prevent water
          from leaching out and to keep out stormwater.

          Transport of ASS to an off-site location must be done in such a manner to prevent
          contamination of land and waterways. Acceptable practice is to cover loads and avoid
          transporting wet materials unless trucks are suitably equipped to prevent liquid spillage.

          Specialist advice is to be obtained where there are activities associated with ASS ie.
          treatment of excavated materials, de-watering of excavations and monitoring of
          groundwater.

4.1.4 Cultural Heritage

          The Director or Site Manager is required to ensure that, unless specified otherwise, the
          areas to be cleared has been inspected for the possible presence of archaeological material
          before commencement of activities. Where archaeological material is discovered, the
          selected subcontracted service personnel must not commence or must cease to prevent
          damage and the relevant personnel at that location and Authorities are to be notified for
          advice to how to proceed. Specialist advice must be obtained where there is the likelihood
          of culturally significant artefacts being found.

4.2       Construction Material Management

          The Director or Site Manager is required to ensure that:

           • Waste metal, timber, plastic and fabric materials are responsibly deposited in selected
             bins and collected by licenced contractors
           • Noise and dust control is in accordance with the requirements 4.5 and 4.8
