7.           IGA Shopping Centre Noise Immissions
7.1          Overview
As presented in Figure 2.1, the IGA Shopping Centre has a loading dock located adjacent the south‐eastern
boundary of the subject site. Additionally, the IGA air‐conditioning and refrigeration plant is located on the
rooftop plant deck near the loading dock area.
Delivery vehicles access the IGA loading area through the existing carpark. It has been assumed that there
would only be a limited number of delivery vehicles required to service the IGA on any given day and only
between the daytime and evening period hours of 7am and 10pm. The loading dock area has the potential
to impact on the multi‐storey unit building shown in Figure 3.1, which is located approximately 16m from
the loading dock.
The noise emissions from the rooftop plant deck have previously been measured by ASK Consulting. It is
understood that some items of plant would operate for 24 hours per day. The mechanical plant deck has
the potential to impact on the multi‐storey unit building, the house lots and the Linea Houses shown in
Figure 3.1, which are located approximately 23m from the rooftop plant deck.

7.2          Noise Source Data
In relation to the loading dock and carpark noise emissions, source noise level data has been adopted from
ASK’s library of noise measurements and is presented in Table 7.1.

                                                                                      77 dBA Lmax @ 10m

                                 Refrigerated Medium Rigid Vehicle passby             72 dBA Lmax @ 10m
                                   Refrigerated Small Rigid Vehicle passby            62 dBA Lmax @ 10m


In relation to the plant deck noise emissions, noise measurements were previously undertaken on the roof
adjacent the plant deck as 57 dBA Leq at 11m.

7.3          Noise Criteria
As discussed in Section 4, it is proposed to adopt the acoustic quality objectives as noise criteria for the
assessment of noise immissions onto the development, these are as follows:
    Daytime and Evening: 42 dBA LAeq,adj,1hr, 47 dBA LA10,adj,1hr and 52 dBA LA1,adj,1hr.
    Night: 37 dBA LAeq,adj,1hr, 42 dBA LA10,adj,1hr and 47 dBA LA1,adj,1hr.


7.4          Predicted Loading Dock and Carpark Noise Levels
The noise emissions from the IGA Carpark and Loading Dock have been predicted at the nearest sensitive
locations onsite.
