Compiled Approved Plans - 132002.220285.I (As Published)

o ALC has been advised that the chillers are switched off at 9pm, hence they have been
considered not to be operational during the night time period.
o The condenser units are considered to be operational prior to 7am.
Commonly used allowance to have 10-15dB noise reduction across facade with partially opened
windows for ventilation to determine the impacts internally. Additional noise reduction will be
achieved, given the residential buildings are likely recommended to have acoustically rated
windows with additional provision for ventilation to allow external windows to be closed. We
note that the basis of judgement is Environmental Protection (Noise) Policy 2019 Acoustic
Quality Objectives which indicates a 20dB difference between outdoor and indoor acoustic
quality objectives which would lead to higher outdoor noise allowances in comparison to our
assessment;
The residential development site ground level on Lots 17-19 are 4.62metres below the loading
dock level as advised by the developer;
The loading dock locations presented in Figure 1.
Loading Dock 1 (Woolworths) is the only loading dock with refrigerated trucks operational and
it is assumed that the refrigeration units are not able to be turned off;
Loading Dock 2 is used by light vehicles;
Loading Docks 3-5 are used by regular trucks;
Loading Docks 2-5 do not have refrigeration trucks and therefore, no idling is allowed with the
exception of a short time pick-up/drop off (less than 10minutes) within the loading dock;
Rear loading dock operational hours

o Monday - Saturday: 5am to 9pm

o Sunday: 8am to 6pm
Vehicles are limited to a speed of 10km/h in the loading dock;
Refrigeration truck idle time of 15 minutes while unloading and this idling was assumed to only
occur in the loading dock, and not along the boundaries or at the entrance to the loading docks.
The refrigeration trucks, therefore, must not enter the site prior to loading to wait for their turn.
Such restrictions should be included if not yet followed (e.g. signs installed at the entry and
along the boundaries of the shopping centre loading docks);
No Idling time for all other trucks including rubbish collection trucks, and such restrictions
should be included if not yet followed (e.g. signs installed at the entry and along the boundaries
of the shopping centre loading docks);
Mechanical plant adjacent and within loading docks is not operational between 9pm and 7am
Monday — Saturday, and 6pm and 8am on Sunday;
Kitchen exhaust fans are not operational between 9pm and 7am Monday — Saturday, and 6pm
and 8am on Sunday;
Compactor operational hours:

o Monday — Wednesday, and Friday — Sunday: 8am to 6pm

o Thursday: 8am to 9pm
No trolley collection between 10pm and 7am;
The following sound power levels:

o Roof condenser units sound power levels 79-93 dB(A) Leg, based on onsite
measurements at Noosa Civic;

o Kitchen exhaust fans sound power levels 98dB(A) and 99dB(A) Leg, based on onsite
measurements at Noosa Civic;

o Loading dock truck sound power level 101dB(A) Lmax at a height of 3m above the ground
level, obtained from onsite measurements at Noosa Civic and similar equipment
previously assessed by ALC;

o Refrigeration truck sound power level of 95dB(A) Leq at a height of 3m above the ground
level, obtained from measurements of similar equipment previously assessed by ALC;
