    Refer to Figure 2 for location on map

2
 Compactor and associated plant only operational between 7am and 6pm. On that basis, at other times
noise impact is N/A – not applicable

3
    Exhaust fan and other plant adjacent to loading docks only operational between 7am and 10pm.

4
  Based on most exposed rooms and building locations as per Figure 4 The rooms assume typical bedroom
and living room dimensions with bedroom glazed façade area of 7.4m2. Subject to final room and building
layouts and the shielding offered by other buildings, the façade acoustic treatment requirements may differ
and would need to be reviewed after plans are finalised.
