Warrawee Substation Page 25Operational Noise & Construction Noise & Vibration AssessmentReport No. 11332 Version BThe ‘Out-of-Hours’ works that have been scheduled for the Electrical Works as listed above inTable 6-10 are to be conducted on weekends during track possession between 7.00am and5.30pm. The planned ‘Electrical Works’ during out-of-hours have to be conducted during trackpossession due to the proximity of the works to the rail line, hence are dependant on theplanned track possession which typically occur over the weekends. The planned dates for theseare as below: 9/6/2012 – 11/6/2012 10/11/2012 – 11/11/2012 9/2/2013 – 10/2/2013 22/6/2013 – 23/6/2013 31/8/2013 – 1/9/2013 9/11/2013 – 10/11/2013 15/2/2014 – 16/2/2014 5/4/2014 - 6/4/2014 30/8/2014 – 31/8/2014 1/11/2014 – 2/11/2014Although predictions have been assessed based on worst-case noise impact, in most casesexcept for a few periods of noisy activity, the noise levels will most likely be lower thanpredicted levels. Whilst the typical highest levels exceed the management levels, they arepredicted to remain below the 75dBA “Highly Affected” limit.
