Jan Swinburne attended the sessions yesterday that were totally focused on noise issues.  A brief summary

• Noise is a large focus of many of the ‘complainants’
• The Metro Rail expert accepted that we would have very high levels of noise inside and outside our apartments
• Need to have predicted high noise level for 40 days in 6 month period before acoustic barriers like double glazing would be considered

• Sleep must be disturbed for 2 consecutive nights before re-location considered
• It is now estimated that the station box construction works will take 6-9 months. That will be the noisiest time with only 6m hoarding as noise protection. Work to be primarily undertaken during normal daytime working hours.

• Most contentious issue is the need for “unavoidable works” which could take place overnight & be noisy.

• Stage 2 work can only occur at night within acoustic sheds or underground
• Night work has to be inaudible in habitable rooms – in theory!
• Under the Resident Impact Mitigation Guidelines there is no respite for daytime works noise. TN43 MM-EES-Technical-Note-043-RIMG-Attachment-A-Residential-Impact-Mitigation-Guidelines-for-Construction
