Review of Environmental FactorsGlenbrook commuter car park and interchange upgradeIn addition and where practicable, it is recommended to provide 2.4 m high hoardings as follows:• On the south and north boundaries of the proposed commuter car park site (Workzone A)in order to block direct line of sight to the adjacent residential receivers.This hoarding would be expected to provide between 5 dB and 10 dB of additional noiseattenuation, if adequately constructed to ensure line‐of‐sight between all receivers andthe construction equipment is broken.• Due to elevated receiver heights and space/access constraints adjacent to Workzone B,installation of hoardings is not considered to be a reasonable mitigation measure in thislocation.As the LAeq(15minute) construction noise levels are predicted to exceed 75 dBA, respite periods mayhave to be observed. This would include restricting the hours that the very noisy activities can occur.Feedback from potentially affected receivers should be considered in selecting appropriate mitigationmeasures.The following standard mitigation measures would be implemented:• Use quieter and less vibration emitting construction methods where feasible andreasonable• Any equipment not in use for extended periods shall be switched off. For example, heavyvehicles should switch engines off while being unloaded• Simultaneous operation of noisy plant and equipment within discernible range of asensitive receiver will be avoided/ limited where possible• Alternatives reverse alarm, such as ‘quackers’ shall be installed• Where attended noise monitoring indicate noise levels are in excess of levels reportedwithin this report and where it is practical and safe to do so, temporary noise screens (orequipment placement) shall be used to shield noisy, fixed works• No swearing or unnecessary shouting or loud stereos/radios on site. No dropping ofmaterials from height where practicable, throwing of metal items and slamming of doors.Ref No: 2260812 51
