7 RECOMMENDATIONS - NOISE EMISSIONS

7.1 MECHANICAL PLANT

The preliminary review of mechanical plant indicates compliance at the closest noise sensitive receivers. However,
the mechanical plant associated with the development has not been selected and therefore, detailed assessment
is required prior to BA phase of the project. The selection of plant and acoustic treatment added to the plant must
ensure that noise emission limits at sensitive sites achieve compliance with the noise emission limits.

Table 22 - Plant Noise Emission Limits

 

 

 

 

Location Equipment Noise Emission Limit dB(A)!
(7am- (7pm- (10pm-7am)
7pm) 10pm)
Sensitive Surrounding Receiver Pumps 55 49 36
Air-conditioning 55 51 39
equipment

 

 

 

 

 

 

 

'Noise emission limits were based on ambient noise levels in Table 2 of the unattended noise monitoring
conducted closest to the site and noise sensitive receivers. The noise limits are applicable at current residential
buildings outside of the development site. Generally, own development will be targeting AS2107:2016 indoor
noise levels.

7.2. OTHER NOISE SOURCES

Other noise sources with any significance are anticipated to include site generated traffic and waste collection.
Waste collection is not anticipated to generate adverse impact onto surrounding developments, given that
collection times would align with the collection times at the adjacent existing residential sites.

Traffic generation from the proposed development is not anticipated to generate adverse impact onto the
adjacent existing residential receivers given that Hofmann Drive will be extended, thus generating higher traffic
noise compared to the proposed development.
