6.3   RESIDENTIAL BUILDINGS FAÇADE CONSTRUCTION

In addition to the management controls, to achieve the indoor noise levels within the considered habitable
areas (refer to Section 5.2), the following minimum façade construction is proposed. Refer to Table 5 for
specific locations where each Façade Type applies.

                         Table 6 – Façade Construction Recommendations

In the case where any of the apartments/habitable areas are elevated with the floor exposed to noise from
the shopping centre, the floor is assumed to be of concrete construction (nominally 150mm thick). Other
construction details may be acceptable but must be reviewed and approved by an acoustic consultant in
order to achieve indoor noise levels of finalised building layouts.

The minimum roof construction must be of concrete or alternative colorbond with Anticon 145 and
plasterboard ceiling with 75mm thick glasswool (11kg/m3) overlay.

Where building layouts and locations or habitable areas differ from what has been considered, additional
assessment is required.

Buildings located further from the loading docks in comparison to the ones considered in this report must
be constructed based on Type A construction as a minimum.
