The modelling predicted the construction noise levels across each section of an
individual work site that would be caused by undertaking the various construction
activities described in section 3. The assessment considered the five construction
stages described in section 3.3.1, with the modelling predictions making no
distinction as to whether certain equipment was restricted from being used at night.
Table 6-18 provides a summary of the noise predictions. It aggregates the
information presented in Appendix D by showing the highest predicted noise levels in
a given work site, opposed to the noise predicted noise levels at each section of a
given work site. This level of information is presented in Appendix D.
The table shows which construction stages would lead to a model-predicted
temporary exceedance of the corresponding day and night time NMLs. The table also
shows the distance from limit of each work site where the NMLs would be achieved
during the day and ay night. The reported data are a summary of the detailed
information provided in Appendix D. As such, the table shows the minimum and
maximum NMLs set for each receiver type within a given work site (ie to account for
the fact that there is more than one receiver for each work site). It also shows the
predicted minimum and maximum noise level from each stage of construction.
The ranges account for the fact that different construction activities (and equipment)
would operate in different locations within the work site (refer to Appendix D for a full
schedule breakdown).
Table 6-18 reports the highest predicted noise levels at a single or number of
receivers close to each work site. It also reports the corresponding NMLs based on
the information in Table 6-16 and Table 6-13. The noise predictions cover the
five anticipated construction work stages as described in Chapter 3. The fifth stage
would require use of the same noise-generating equipment as the first stage. As
such, the noise impacts would be the same. The table shows:
Residential receiver exceedances
- Highly noise affected (bold red text and grey shading)
- Noise affected (daytime) (bold red text)
- Noise affected (other times) (bold black text)
- No exceedances (un-bolded, un-shaded text)
Sensitive and commercial receivers
- Exceedance (bold back text)
- No exceedances (un-bolded, un-shaded text).
Appendix D also reports the distances from the proposal footprint where each of the
NMLs would be satisfied.
