Proposed RSL Retirement Village, Cooroy - Road and Rail Noise Assessment (Revised) —-

 

solution for reducing construction material requirements. After review of the predicted modelling
results, consideration has been given to the following:

= replace ILU Buildings 3, 4, 30 with Type 1 ILU layouts;

» construction of ILU Buildings 93 to 118 with alternative layouts in which living areas face the
Cooroy Connection Road and bedroom areas are located to the rear (see Figure 9 for potential
single unit tayout); and

= construction of an acoustic barrier extending at least 1 metre from the Bedroom 2 wall (for the
alternative unit). The barrier should be 1.8 metres above finished floor levels and be located
adjacent to the Bedroom 2 window (see Figure 9).

A potential unit layout appropriate for replacing Type 1, 2 and 3 ILU unit buildings located adjacent
to the Cooroy Connection Road is presented on Figure 9. Table 5.9 and 5.10 presents predicted
STC requirements based on the above design alterations.
