MCU14/0056 - Attachment F - Acoustic Assessment

5.2 Assessment of Predictions

Predicted mixed-use noise levels as shown in Table 5.4 and Section 4.5 meet the nominated criteria
with the exception of delivery vehicles (refrigerated) in the loading dock area, mechanical plant and
trucks manoeuvring outside the service station area. Mechanical plant exceedances would require
additional analysis and may utilise options such as barrier shielding, placement, quiet equipment
selection to ensure limits are met.

The following recommendations are made:

         Construction of acoustic barriers as per Figure 5.1. The barriers should be solid and
          continuous with negligible gaps and a minimum surface density of 12.5 kg/m 2.
         Deliveries and refuse collection (with the exception of fuel) should be during the daytime
          (7:00 am to 6:00 pm) only.
         Site access should be restricted to Myall Street entry/egress during the nighttime.
         Mechanical plant for the purposes of assessment was assumed to determine a benchmark as
          the mechanical plant for the proposed development is yet to be selected. It is proposed that
          during the detailed stages of the project, an assessment of the mechanical plant noise
          emissions using the actual plant model selections and installation arrangements be made to
          ensure that the nominated limits are met. Therefore noise limits are proposed to inform the
          selection of mechanical plant for the development. Table 5.3 presents noise limits to be met
          at the nearest existing sensitive receivers to the proposed development.
