1 INTRODUCTION

Acoustic Logic consultancy (ALC) have been engaged to conduct an assessment of major noise source
impacts from the Noosa Civic Shopping Centre onto proposed adjacent residential development.

The report is in response to the Council’s request:

1.

Prepare and submit to Council for approval with and Operational Works application a revised acoustic
report which includes measures to mitigate noise generated from the shopping centre operations and
equipment, including deliveries, truck movements and rubbish collection. This report should consider
attenuation at the noise source as well as a noise barrier along the shared boundary of Lots 19 and
217. All measures to mitigate noise must be implemented prior the submission of the subdivision plan
to Council.

Noise attenuation is required to achieve the following acoustic quality for potential residential uses on
Lots 17-19. The measurement location must include receivers being places at the closest point to the
future residential and office buildings.

 

 

 

 

 

Criteria (measured at the receptor) dB(A)
Sensitive receptor Time of Day LAeq.adj, Thr? LAT adj, Th
Daytime and evening
(habitable spaces) 35 e
Dwelling (indoors)
Night-time (sleeping
areas) 30 40

 

 

 

 

 

"Acoustic descriptor/noise target for continuous noise sources (eg. Mechanical plant).
“Acoustic descriptor/noise target for transient impacts arising from loading dock activities (e.g. truck
movements, reversing alarms, compactor, trolley etc.)

The purpose of this assessment is the following:

Establish the predicted intrusive noise levels at the proposed subdivision site on Hofmann Road for
lots 17-21.

Provide acoustic attenuation recommendations to meet the indoor acoustic criteria set by Noosa
Shire Council. These are applied at the source, boundary, and receiver.

This report includes attended and unattended noise measurements from the previous ALC acoustic report
(ref: 20191414.1/1501A/R2/SS, dated 15/01/2020).

5 NOISE SOURCES/IMPACTS

The following sections outline current major noise sources that were identified upon the previous site visit
to have potential impact on site.

5.1 LOADING DOCKS
5.1.1 Trolley Collection

During time on site, it was observed that trolley activity is a regular occurrence across both loading docks.
Noise level that was measured in relation to noise produced by trolley activity was 69 dB(A) Leg. Trolley
collections is understood to only occur during day and evening periods (i.e. 7am to 10pm) which is also
considered in this assessment.

5.1.2 Delivery Trucks

It was observed that small to medium sized delivery trucks were present within the loading docks during
time of site visit with no more than 1 truck in each hour at the loading docks. As advised by the client, we
note that the loading dock operational hours start at 3am and can run up to 10pm. Truck (incl. refrigeration
truck) idling was only assumed to occur in the loading dock during nominal 15minute loading period, and
not along the boundaries or at the entrance to the loading docks. Where trucks enter the site to wait for
loading and generally during loading (unless short-time drop-off/pick-up), engines must be turned off and
in case of refrigeration trucks, these should just come in and leave site after loading as no idling would be
allowed at other times. Such restrictions should be included if not yet followed (e.g. signs installed at the
entry and along the boundaries and within the shopping centre loading docks).

5.1.3. Mechanical Plant
The following mechanical plant was observed and noted in Figure 2.

e Eastern Loading Dock Plant deck above loading dock ‘5’ emitting a calculated sound power level
of 93dB(A).

e Kitchen exhaust sound power level of 99dB(A).

e Western Loading Dock - Plant room/exhaust adjacent loading dock ‘2’ were measured and
calculated to have a sound power level 90 dB(A).

Other plant is generally located on the rooftop of the shopping centre and therefore, providing significant
noise shielding. In any case, the assessment is based on a sound power level of 90dB(A)

At night, our predictions are based on kitchen exhaust fan being turned off together with other plant
adjacent to loading docks.

No other mechanical plant was considered and located during site inspections. In case of additional other
plant, these must operate to ensure that the Loo background noise levels at the future residential buildings
are not exceeded.

5.1.4 Compactor

A compactor was noticed located by the ‘Big W’ loading dock 3 with an assumed Lmax Sound power level of
100 dB(A). Compactor operation has been excluded from night time assessments as it should only operate
between the hours of 7am and 6pm.

5.2 NOISE CALCULATION

Measured noise levels and mechanical plant noise data and operational conditions highlighted in the
previous section have been used to calculate the predicted intrusive noise levels at the sensitive noise
receptors (lots 17, 18, 19, and 21) based on the expected building layouts of the Lots as described below
and indicated in the figures below.

A SoundPLAN™ computer model was developed for these noise sources as described activities and used to
predict noise emissions from the compactor and loading docks to the sensitive receptors (lots 17, 18, 19,
and 21). Predictions were made for the following scenarios:

e Allloading docks and compactor operating concurrently, representing the worst-case scenario
for day time noise emissions.

e All loading docks operating concurrently, representing the worst-case scenario for evening and
night time noise emissions as per the description in Section 5.1;

e Only the compactor operating within the hours nominated and assumed.

e Mechanical plant operational scenarios as described in this report.

The analysis was conducted based on the following assumptions:

e Mechanical plant decks indicated in Figure 2 have a sound power level of 90 dB(A) Leg each.

e Kitchen exhaust fan indicated in Figure 2 has a sound power level of 99dB(A) Lea;

¢ Loading dock trucks have a sound power level of 101 dB(A) Linax.

e Refrigeration trucks were assumed to idle for 15 minutes whilst unloading, with a sound power
level of 95dB(A) Leq at a height of 3m above the ground level. This idling was only assumed to
occur in the loading dock, and not along the boundaries or at the entrance to the loading docks.
The refrigeration trucks, therefore, must not enter the site prior to loading to wait for their turn.
Such restrictions should be included if not yet followed (e.g. signs installed at the entry and
along the boundaries of the shopping centre loading docks).

¢ For all other trucks, no idling was assumed within the sites within short term drop-off/pick-up
occurring at the loading docks only (less than 10minutes) and such restrictions should be
included if not yet followed (e.g. signs installed at the entry and along the boundaries of the
shopping centre loading docks).

¢ Compactor indicated in Figure 2 has a sound power level of 100dB(A) Linax.

e Kitchen exhaust fans being turned off between 10pm and 7am and other plant adjacent and
within loading docks not operational after 10pm and prior to 7am.

¢ Compactor is not operational between 6pm and 7am;

« No trolley collection between 10pm and 7am.

e The presence of a 6m wide plantation buffer between the northern boundary of the residential
lots and the shopping centre paved loading dock and entry boundary.

e Facade line of proposed residential development approximately 8 metres from loading dock
boundary (refer to the closest sensitive receiver buildings used in calculations indicated in figure
below)

2 Compactor and associated plant only operational between 7am and 6pm. On that basis, at other times

noise impact is N/A — not applicable

3 Exhaust fan and other plant adjacent to loading docks only operational between 7am and 10pm.

* Based on most exposed rooms and building locations as per Figure 4 The rooms assume typical bedroom
and living room dimensions with bedroom glazed facade area of 7.4m”. Subject to final room and building
layouts and the shielding offered by other buildings, the facade acoustic treatment requirements may differ
and would need to be reviewed after plans are finalised.

6 RECOMMENDATIONS

6.1 MANAGEMENT CONTROLS

It is recommended that operation of the compactor to be limited to the day time period only (7am - 6pm)
and not use kitchen exhaust and other mechanical plant adjacent to the loading docks between 10pm and
7am.

Furthermore, trolley collection must not occur after 10pm and prior to 7am.

Loading dock operation is to be limited to the time period between 3am and 10pm only, with refrigeration
trucks recommended to idle for a maximum of 15 minutes during unloading. This idling shall only occur
during the loading/unloading activity at the loading dock, and not whilst waiting to enter the loading dock
or along the boundaries. In the case of refrigeration trucks, planned entry times could be scheduled before
hand to ensure that no idling occurs along the boundaries or at the entry to the loading docks.

For all other trucks, no idling should occur within the sites at any time also with the exception of a short-
time pick-up/drop-off within the loading dock.

Such restrictions should be included if not yet followed (e.g. signs installed at the entry and along the
boundaries of the shopping centre loading docks and within loading docks). Furthermore, If trucks are to
remain idling whilst waiting to enter the loading dock, it is recommended that this is done away from the
site as otherwise the impacts can be adverse.

6.2 ACOUSTIC BARRIER

An acoustic barrier is recommended along the northern boundary of lots 21 and 19 adjacent to the
blockwork loading dock wall as shown in Figure 19. The height of the barrier must be a minimum of 1.8
metres above the loading dock ground level or top of the existing loading dock blockwork wall whichever
is higher, with a minimum surface density of 12 kg/m. This assumes that the pad heights of the residential
buildings do not exceed that of the loading dock concrete pad level.

6.3 RESIDENTIAL BUILDINGS FACADE 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 facade construction is proposed. Refer to Table 5 for
specific locations where each Facade Type applies.

Table 6 - Fagade Construction Recommendations

 

Type Glazing Systems Facade Wall

 

A Nominal openable glazing system - Rw33 Masonry construction or Cladded
nominally with 6.38mm lam glass and seals | facade (9mm fibre cement sheet)
on 90mm timber studs - cavity
insulation (e.g. 75mm thick
11kg/m3 glasswool) — min 10mm
thick plasterboard internally

 

B Nominal openable glazing system - Rw35 Masonry construction or Cladded
nominally with 10.38mm lam glass and facade (9mm fibre cement sheet)
acoustic seals on 90mm timber studs - cavity

insulation (e.g. 75mm thick
11kg/m3 glasswool) — min 13mm
thick Fyrchek plasterboard

 

internally
Cc Nominal openable glazing system - Rw37 Masonry construction or Cladded
nominally with 10.76mm lam glass and fagade (9mm fibre cement sheet)
acoustic seals on 90mm timber studs - cavity

insulation (e.g. 75mm thick
11kg/m3 glasswool) — min 2 layers
of 13mm thick Fyrchek
plasterboard internally

 

 

 

 

 

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.

7 CONCLUSION

ALC have conducted a noise impact assessment of the loading dock activities and mechanical plant located
at Noosa Civic Shopping Centre, 28 Eenie Creek Road, Noosaville. The purpose of the assessment was to
determine the predicted intrusive noise levels at the proposed subdivision site on Hofmann Road for lots
17, 18, 19, and 21. Previous noise monitoring data conducted by ALC (ref: 20191414.1/1501A/R2/SS, dated
15/01/2020) has assisted in establishing the acoustic environment associated to the subject site (Table 1 and
2).

Provided the recommendations in Section 6 are implemented, the development is predicted to achieve
compliance with the Noosa Shire Council assessment indoor noise criteria.

We trust this information is satisfactory. Please contact us should you have any further queries.
