The underside of the solid roof over that part of the outdoor dining area closest to the café and shared
space, a ceiling area approximately 6 metres by 22 metres plus 7 metres by 2 metres, has acoustic
absorbent panelling incorporated into this ceiling. This acoustic absorbent panelling is contained in
one area which is approximately 5 metres by 15 metres, and represents approximately 51% of the
total ceiling surface area.

Given the small area of the shared space (which presumably could be used for dining) compared to
the total of the outdoor dining area all calculations of patron noise impact have assumed that all
patrons are outdoors. The fact that some patrons could be inside (in the shared space) would not
make any significant difference to the noise impact calculations (regardless of doors to this shared
space open or closed).

For the café and outdoor dining area the total capacity has been assumed to be 150 persons, and this
space will trade from 0600 hours to midnight, daily. The assumed patron numbers, for the purpose of
calculating noise impact, are:

        0600 to 0700 hours:          30 patrons;
        0700 to 2200 hours:          up to 150 patrons;
        2200 to midnight:            100 patrons.

Based on these patron numbers for the different time periods patron noise impact was calculated to all
of the closest residential, namely Blocks 2, 14, 18-21 and 3 and 4. With due consideration of the
following:

    1. residential elevated above the outdoor dining area and the roof of the dining area acting as an
       acoustic barrier for some of the diners (particularly Blocks 18 to 21);

    2. angle of view to the outdoor dining area;

    3. barrier effect of the intervening roof of the Facilities Building (for Blocks 3 and 4);

    4. solid balustrading at least 900 to 1000 mm high to the following balconies:

                  Block 2, south facing balconies;
                  Block 3 and 4, eastern facing balconies;
                  Block 14, southern aspect of balconies;
                  Block 18, 19, 20 and 21, west facing balconies.

patron noise was calculated to the closest external living areas and compared to the time varying
noise limit criteria. For all of the above residential Block balconies the daytime and evening (and early
morning) noise limits were complied with. For the night-time period, 2200 hours to midnight, for some
balconies, the noise limit criteria was exceeded by up to 1 dB(A). This magnitude of exceedance is
not significant and no additional noise control measures are required.

All of the above is with respect to patron noise impact to the closest residential external living areas,
the night-time noise criteria for which also equates to immediately inside the apartment with windows
and doors open. Inside the closest residential apartments, with windows and doors closed, the noise
level of patrons would be at least 15 to 20 dB(A) less and easily comply with the internal noise criteria.

The noise control measures for patron noise in the outdoor dining area/cafe are:

        outdoor dining area/café not to commence trading until 6:00 am daily;
        outdoor dining area/café not to trade after midnight, daily;
        outdoor dining not to extend beyond the outdoor dining area;
        solid balustrading at least 900 mm high to the following balconies:
              o Block 2, south facing balconies;
              o Block 3 and 4, eastern facing balconies;
              o Block 14, southern aspect of balconies;
