3 SITE DESCRIPTION

The proposed development is located at 88-92 Smith Street, Collingwood. The proposed development is located in an area which currently includes retail, commercial and residential offerings or a combination of more than one type. The development will incorporate two residential towers and will consist of the following

1. Common basement level which including storage facilities 2. Lower ground level (fronting Little Oxford Street) which includes

a. carparking facilities b. two separate lift lobbies (one for each tower) c. substation d. single retail tenancy offering facing Little Oxford Street.

3. Three retail tenancies are proposed on the Upper Ground Level which is faces and is level with Smith Street with residential dwellings while residential dwellings are proposed solely at this level within the Little Oxford Street tower.

4. From levels 1 through 6 each tower will incorporate residential dwellings.

The site is bounded by various mixed uses including Smith Street to the west which carries both vehicles and also includes tram services. Little Oxford Street forms the eastern boundary of the site and carries low traffic volumes servicing the existing dwellings. Existing retail/commercial tenancies are located along the northern boundary fronting Smith Street while residential apartments are

located to the north fronting Little Oxford Street, commercial and residential uses to the south and

existing commercial development to the east across Little Oxford Street.

During inspection it was note that the dominant noise sources are traffic and tram movement on

Smith Street, music noise during Friday and Saturday Nights from night clubs across the street and

kitchen exhaust fans to the north of the site serving the retail offerings along Smith Street. It was

also noted that some music noise from the Lazer Pig Pizza restaurant was audible at the north

eastern boundary of the site.

An outdoor dining area located at the rear of the restaurant located at 96 Smith Street site was also

noted and noise associated from patrons using the outdoor dining area was audible along the

northern boundary however no music was played in that location. Finally two kitchen exhaust fans

serving the restaurants within the 96 Smith Street site were audible. Figure 1 below shows the

subject site location and surrounding area.

The adjoining site located at 86 Smith Street incorporates existing residential dwellings with an

apartment bedroom with openable windows within the Smith Street facade elevation facing existing

night clubs. The same site has also been approved for a four storey development incorporating

additional residential dwellings.

3.1 LOCAL NOISE SOURCES

Acoustic Logic Consultancy attended the site on multiple occasions both during the day and night

time period. The following observations were made with respect to the subject site.

• Traffic noise, including tram noise, associated with Smith Street is the dominant noise

source. Traffic noise associated with Little Oxford Street is sporadic and associated typically

with vehicles accessing development located along Little Oxford Street.

• Inspection of the site indicated that music noise was a dominant noise source during the

late evening and night time period. Music noise at the subject site was governed by that

associated with the two night clubs located across Smith Street namely Sircuit and Yah Yahs.

Monitoring indicated that music noise was played until 3am

• In addition inspection at the rear of the site indicated two other primary noise sources, the

existing outdoor dining area immediately to the north of the site and the kitchen exhaust

fans serving the same development (refer figure 2 below). Both noise sources were audible

along at the northern boundary.

4 ENVIRONMENTAL NOISE DESCRIPTORS

Environmental noise constantly varies in level, due to fluctuations in local noise sources including

road traffic. Accordingly, a 15 minute measurement interval is normally utilised. Over this period,

noise levels are monitored on a continuous basis and statistical and integrating techniques are used

to determine noise description parameters.

In the case of environmental noise three principle measurement parameters are used, namely L10,

LgO and Lea.

The L10 and L90 measurement parameters are statistical levels that represent the average maximum

and average minimum noise levels respectively, over the measurement intervals.

The L10 parameter is commonly used to measure noise produced by a particular intrusive noise

source since it represents the average of the loudest noise levels produced by the source.

Conversely, the Lgo level (which is commonly referred to as the background noise level) represents

the noise level heard in the quieter periods during a measurement interval. The Lgo parameter is

used to set the allowable noise level for new, potentially intrusive noise sources since the

disturbance caused by the new source depends on how audible it is above the pre-existing noise

environment, particularly during quiet periods, as represented by the Lgo level.

The Lea parameter represents the average noise energy during a measurement period. This

parameter is derived by integrating the noise levels measured over the measurement period. Lea is

important in the assessment of traffic noise impact as it closely corresponds with human perception

of a changing noise environment; such is the character of industrial noise.

5 NOISE LEVEL MEASUREMENTS

Manned and unmanned noise monitoring measurements were conducted at and around site to

determine the existing acoustic environment. Monitoring data from three unmanned noise

monitors placed on the existing roof recorded noise levels.

5.1 MEASUREMENT LOCATIONS

Measurements were undertaken at locations as indicated in Figure 1. Additional measurements

were conducted at site during the night time period to determine existing levels of music noise from

operation of the nightclubs located across Smith Street. Photos of the logger locations can be found

in Appendix 3 — Site Photos

5.2 TIME OF MEASUREMENT

Long-term unattended noise monitoring was conducted from 21st August to 25th August 2015 on

• the existing roof as shown in figure 1, (refer Appendix 3 showing monitors locations).

Manned noise measurements of the traffic, including trams, at the west facade of the proposed site

were also conducted on 21st August between 3:00pm and 5:00pm.

Attended measurements were conducted on the 22'd August between 11:00pm and 2.30am in

order to measure noise from nightclub activities, patron noise, and mechanical plant and equipment

noise.

5.3 MEASUREMENT EQUIPMENT

Two Ngara noise monitors (serial numbers 87801e and 878056) and an ARL-315 (serial number 15-

203-519) was used for the unattended noise monitoring. The noise monitors were programmed to

store 15-minute statistical noise levels through the monitoring period. Equipment was calibrated at

the beginning and the end of the measurements; no significant drift was detected. All

measurements were taken on fast response mode. Refer Appendix 2 for noise logging data.

A Norsonic Nor140 Sound Level Analyser was used for the manned noise level measurements. The

Norsonic was calibrated using a B&K Type 4231 calibrator. The analyser was calibrated at the

beginning and the end of the measurements; no significant drift was detected. All measurements

were taken on fast response mode.

6 ASSESSMENT CRITERIA

Inspection on site indicates that traffic noise (including tram noise) from Smith Street is the

dominant noise source along on the western site boundary generally. During inspection and testing

noise from the nightclubs located to the west of the site across Smith Street were also clearly audible

and has the potential to impact the subject site but typically occurs during the late evening and night

time period primarily on Friday and Saturday nights.

Additionally, noise from patrons and mechanical plant associated with the adjacent restaurant

located to the north of the site was clearly audible at the subject site. Finally plant and equipment

serving the development shall be treated to ensure compliance with SEPP N-1.

To address Condition 11 of the Planning Permit, the following assessment criteria has been

established.

6.1 PLANT AND EQUIPMENT SEPP N-1

To ensure that noise emissions from the mechanical plant serving the development do not impact

adversely on the amenity of future occupants or neighbouring dwellings, noise levels emitted from

the plant equipment shall comply with EPA guidelines.

6.1.1 Environmental Noise

SEPP N-1 details the methodology to be used in assessing environmental noise emissions such that

protection of residential amenity may be preserved. SEPP's are statutory instruments that are

required to be complied with by private individuals, public and private sector organisations. SEPP

N-1 includes both Schedule A and B that provide procedures to measure noise from premises and

to determine noise emission limits respectively. To determine the assessment criteria both the

'zoning' level and ambient background noise levels are required to determine if the background

noise level is neutral, high or low.

6.1.2 Zoning Level

The 'Zoning' level is determined by the Influencing Factor (IF) and is calculated by the formula

nominated in section B.2.4 of SEPP N-1, the 'Zoning Level versus Influencing Factor' graph in section

B3 of SEPPN-1 and Victoria's Planning Scheme Maps. The IF is calculated from the proportion of

industrial and commercial land around noise sensitive areas (in this case residential premises).

Review of the surrounding area indicates an IF of approximately 0.45 which results in the zoning

limits detailed in Table 11 below.

Note: Measured noise level presented have been corrected -2.5 dB(A) for facade reflection. The background noise levels

are based on noise levels measured at the eastern side of the site at location 4.

6.1.4 Fixed domestic plant

Part 1 of the EPA Noise Control Guidelines (Publication 1254, October 2008) require the following for noise associated from domestic air conditioning units impacting on adjoining residents of another SOU:

1. Fixed Domestic Plant and Home Occupation Noise

(such as domestic air conditioners, swimming pool equipment, spas, ducted heating, internal

vacuum systems and home occupation noise)

Night operation

Noise from any fixed domestic plant must not be audible within a habitable room of any other residence (regardless of whether any door or window giving access to the room is open) during prohibited hours prescribed by the Environment Protection (Residential Noise) Regulations 2008.

The following prohibited hours apply to air conditioners, swimming pool and spa pumps,

ducted heating systems and the like:

• 10 pm - 7am Monday-Friday. • 10 pm - 9 am weekends & public holidays.

Day/evening operation (non-prohibited times)

I:\Jobs\2015\20151121\20151121.2\20170406MSA_R2_Planning 14 Permit Report.docx

Where noise from any fixed domestic plant is audible beyond the boundary of the residential premises on which the plant is situated, the intrusive noise shall not exceed the background noise level by more than 5 dB at the measurement position.

Noise assessment must be made in accordance with noise assessment techniques listed in section 17 of these guidelines. Adjustment for tonality and/or impulsiveness must be included if applicable.

The criteria for noise emission from domestic plant has been summarized in Table 13 below.

Table 13 — EPA criteria for Fixed Domestic Plant

Noise Source Period Criteria

Domestic air conditioning unit including apartment

condenser units located on balconies

Daytime/Evening 51 Leq dB(A)

Night time Inaudible within adjoining residence. This may require air-conditioning units

to be switched off.

6.2 TRAFFIC NOISE

Internal noise level criteria for external noise intrusion from traffic associated with surrounding

streets has been developed in accordance with Australian Standard AS/NZS2107:2000

"Recommended Design Sound Levels and Reverberation Times for Building Interiors".

AS/NZS 2107:2000 sets out recommended design sound levels for residential developments

depending on locality to minor or major roads. The Table below details the criterion set for this

development with assessment based on typical repeatable level.

Table 14 — Internal Noise Level Criteria — Traffic Noise

Living rooms 35 - 45 N/A

Note 1: Bedrooms are assessed as living areas outside the night time period of 10pm to 7am. Assessment is based on apartments suitably furnished ready for occupation.

6.3 ADJACENT ROOFTOP PLANT

To ensure that noise emissions from the existing nearby rooftop plant do not impact adversely on

the amenity of the proposed residential development, the proposed residential development

should where possible be designed to comply with SEPP N-1.

It is noted that SEPP N-1 provides assessment criteria applied to external areas on the proposed

development site. Where compliance with SEPP N-1 external noise criteria cannot be met externally

then SEPP N-1 does provide guidance on assessment based on apartment windows and doors being

fixed closed.

I: Vobs\201.5 \20151121\20151121.2\20170406MSA_R2_Planning 15 Permit Report.docx

Review of measured noise emissions from the existing neighbouring rooftop plant indicates that the following would be required to ensure compliance with SEPP N-1

1. Designing apartments without openable windows (designing for compliance with SEPP

N-1 based on no openable windows or accessible balconies) contravenes other

development controls with respect to openable windows and reduces active street

frontage and cross ventilation within dwellings and therefore cannot be adopted.

The above options has been reviewed but cannot be applied without imposing design constraints which makes them unviable.

Based on the above the subject site has been assessed to the following criteria based on the

requirements of State Environment Protection Policy N-1 (SEPP N-1) while retaining the option for

residents to ensure apartment windows may be openable.

SEPP N-1 states that where the noise is transmitted through a solid wall, ceiling or floor the

adjustment to the external noise limit shall be 15dB.

Based on the above and that the development is the agent of change it would not be unreasonable

to expect future residents to close windows and doors to provide a suitable internal amenity. It is

also noted that the adjacent rooftop plant would be assessed to night time criteria which would

result in compliance with day and evening criteria.

The following internal design criteria are proposed based on achieving an acceptable internal noise

level while retaining the option for residents to ensure apartment windows may be openable.

Table 15 — Internal Design Criteria - Adjacent Rooftop Plant

Area Internal Noise criteria with external

windows and doors closed'

Habitable Rooms (Night Period) 32 dB(A) Leq(30 min)

1— Assessment criteria is the external SEPPN-1 criteria for the period-15dB. It is noted that the plant does not operate during the night period.

6.4 MUSIC NOISE

Inspection of the adjacent buildings indicates that the existing building located at 86 Smith Street

incorporates existing residential dwellings (Appendix 3), and in particular a bedroom located on

level 1 facing directly onto Smith Street with openable windows. It is also noted that the adjoining

site has been approved to expand the existing residential component of the site. The proposed

development therefore does not result in an agent of change as it is immediately adjacent to an

existing residential development at 86 Smith Street.

As there is already an exceedance of SEPP N-2 noise limits at the 86 Smith Street development

compliance with SEPP N-2 is not the responsibility of the subject development. Therefore noise

control works to comply with Clause 52.43 (that is to achieve SEPP N-2 compliance indoors) is not

required to be implemented in this instance.

Notwithstanding the above it is recommended that assessment criteria be adopted to address

external noise levels from music generation. The following internal noise objectives are proposed

for the subject development.

6.5 PATRON NOISE

Council has requested that although there is no statutory assessment criteria for patron noise, that

amenity for future residents be addressed associated with the outdoor dining area serving the

restaurant located at 96 Smith Street. Council have requested that assessment of patron noise be

based on providing internal amenity with apartment windows and doors being closed and internal

noise objectives be based on AS/NZS2107:2000. Table 17 below presents internal noise criteria

based on typical repeatable level in apartments suitably furnished ready for occupation.

7 SMITH STREET NIGHT CLUBS

Music associated with night clubs was clearly audible at the subject site and dominated by both the

Sircuit and Yah Yahs night clubs. No other music noise was audible at the subject site on Smith

Street. State Environment Protection Policy (Control of Music Noise from Public Premises) No. N-2

sets criteria applicable to music noise associated with licensed premises during the night period as

LOct90 + 8dB. Criteria formulated based on SEPP N-2 are presented in Table 18 below.

As indicated above as there is already an exceedance of SEPP N-2 noise limits at the 86 Smith Street

(existing residential dwellings) compliance with SEPP N-2 is not the responsibility of the subject

development. Therefore noise control works to comply with Clause 52.43 (that is to achieve SEPP

N-2 compliance indoors) is not required to be implemented in this instance and therefore non-

compliance remains the responsibility of the operators of those facilities.

7.1 LAZER PIG PIZZA

During testing and inspection it was noted that some music noise was audible at the proposed

development on Little Oxford Street. However as existing residential receivers are located closer to

the restaurant provided noise emissions from the restaurant comply with SEPP N-1 and N-2 criteria

at those locations noise emissions will comply at the subject development and as such no additional

ameliorative measures are required.

9 EVALUATION OF NOISE INTRUSION

Internal noise levels will primarily be as a result of noise transfer through the windows, doors and

roof as these are relatively light building elements that offer less resistance to the transmission of

sound. Walls that are proposed to be heavy masonry elements will not require upgrading. The

predicted noise levels through the windows, doors and roof are discussed below. The predicted

noise levels have been based on the expected level and spectral characteristics of the external noise,

the area of building elements exposed to external noise, the absorption characteristics of the rooms

and the noise reduction performance of the building elements.

Glazing/facade treatment was determined based on the following

• For each facade, the highest expected façade noise level was used for the whole facade. No

correction for vertical elevation change was made.

• Assessment of traffic noise was based on the typical repeatable measured LAeq lhour noise

levels.

• Transmission loss of facade element.

The constructions set out below are necessary for the satisfactory control of external noise.

9.1 RECOMMENDED GLAZING

The minimum glazing requirements schedule for this development can be found in Appendix 1 —

Glazing Schedule. The glass thicknesses shown in the schedule do not take into account thermal,

structural, safety or any other requirements other than acoustic requirements and thus may require

upgrading in some instances. In these instances, increasing the glass thickness beyond the acoustic

requirement will be acceptable. Where the glazing thickness has not been specified, standard

glazing will be acceptable. Note that mohair seals in windows and doors are not acceptable where

acoustic seals are required.

The below details the minimum performance requirements for the glazing assembly installed.

Where open-able windows or sliding glass doors are installed, the total Rw performance of the

system shall not be lower than the values listed. It is noted that the system supplied shall meet the

overall minimum Rw ratings nominated. If an alternative system is proposed the system shall be

reviewed and will require approval by a suitably qualified acoustic consultant to ensure that the

proposed system is acceptable and will ensure compliance with the nominated internal noise design

criteria.

9.2 WINTER GARDENS

The development will require winter gardens to be installed generally in the areas located in the

markup in Appendix 1. This can be achieved inclusion of glazing from slab to slab in the form of

glazed windows or glazed louvres or similar. Where these are installed the glazing system shall

achieve a minimum Rw 22 rating. The facade treatment applicable with the inclusion of a winter

garden is indicated in the Appendix 1.

9.3 EXTERNAL WALLS

External walls are proposed to be of brick veneer construction and will typically not require

upgrading acoustically. It is proposed that an additional layer of plasterboard be installed locally

facing Smith Street as indicated Appendix 1.

9.4 CEILING CONSTRUCTION

All roof systems are proposed to be constructed from concrete minimum 150mm thick with

suspended plasterboard ceiling which will be acceptable acoustically.

9.5 SOLID SCREENS

Analysis of noise from operation of the night clubs on Smith Street, indicates noise levels will exceed

SEPP N-2 at the location indicated below. Based on analysis of measured noise levels the following

methodology is proposed.

Exceedance

Figure 3 —Smith Street Night Clubs Predicted SEPP Emissions

1. A solid screen to the light court is recommended to be installed.

2. The solid screen shall be constructed from a solid imperforate material eg masonry wall,

9mm FC sheet, or minimum 6mm glass or similar solid imperforate material. Refer

Appendix 1 for extent of what screening is indicated.

9.6 NOISE MASKING

Noise masking within apartments is not required to achieve internal noise criteria. Noise masking

however may be considered as part of apartment design for dwellings facing Smith Street due to

the inclusion of winter gardens which significantly reduce background noise levels.

10 MECHANICAL PLANT AND EQUIPMENT

It is noted that plant and equipment selections/design have not yet been finalised. Therefore to

ensure amenity for future residents and nearby noise sensitive receivers is preserved, mechanical

plant equipment shall be designed to ensure noise levels comply with the criterion nominated in

Table 12.

This will be achieved by the use of standard acoustic treatment such as internally lined ductwork,

acoustic attenuators, variable speed drives, solid screens and vibration mounts.

11 GARAGE DOOR — NOISE AND VIBRATION

This section addresses Condition 11(c) of the Planning Permit. The planning permit condition

requires noise levels from the carpark gate and car park stackers to not exceed 55 dB(A) Lmax

outside openable windows of bedrooms. To achieve this requirement the following will be required

• To ensure compliance the following treatment is recommended for the main car park entry doors:

• The car park floor surface is to have a broom finish or alternative to address tyre squeal.

• Carpark entry doors shall be vibration isolated from the building generally in accordance with

the following details.

• Doors shall be quiet in operation.

• Teflon guides shall be installed in all rails.

• Ensure that door panels do not rattle, and the operation of any door guides, rollers, etc is

smooth.

• Door guides should be fitted with vibration isolated fixings where required. Refer below.

• Door motors shall be fitted with a soft start/stop controller to minimise noise.

• The door shall be stopped approximately 5 mm from the slab/ground to ensure the base of

the door does not contact the concrete surface.

• Operation of the door shall comply with EPA SEPP N-1

• Isolation of the door structure is shown in the Figure 11-3 below

• It is noted that solid screening to the carpark stacker system maybe required to address noise

emissions. Requirement to install treatment would be subject to acoustic testing once the car

stacker system is operational and that solid screening to the carpark stacker system in the

area indicated below may indicate that treatment is not required.

o Indicative extent of and proposed treatment is indicated below. Cladding of the

stacking area would indicatively run as close as practicable to the slab soffit over.

o Final cladding material would be determined upon confirmation of test results once

the car stacker is operational, however it is expected where cladding is required

that sheet metal nom 0.5mm thick would be acceptable.

• In addition refer to Section 12 for absorptive treatment to slab soffit.

Hi Diane,

Hope you are well. This email is to Just follow up on our discussion this week regarding the current report that you are reviewing with Council. We understand Council's

concerns with respect to the car stacker treatment and hence the report has endeavoured to provide certainty that the development can ameliorate noise emissions from car stacker operation. To this end we note the following concerns raised by Council raised by Vicky

"Hi Henry,

We need a clear and unambiguous report. So if you could please get those tidy-ups done and resend that report then we can proceed.

We want a report that confirms that by enclosing the stacker system the 55db requirement will be met — whilst still maintaining the garage door as permeable. If you could provide that ASAP then Michelle can send this to our acoustic engineer whilst she is on leave then finalise when she is back.

Thank you

Vicky"

The report we have prepared as discussed incorporates the following

1. No cladding to the carpark entry doors will be installed. It is understood that Council require the carpark to be visually connected to the street 2. Treatment to the car stacker in principle has been proposed as indicated below. We note that this would be determined with on site testing which may find that

some or all of the cladding is not required provided the criteria nominated namely 55 dB(A) is achieved and nominated in the spec.

CAR STACKER' TRENCWA.00 4100

-5 CARS

CAR STACKF-R TREN13;41R10 4300 . 8 CARS

Note A

Note A: Indicative extent of solid imperforate cladding to the car stacker area opposite the souther carpark entry door. Where required install 50mm thick 32 kg/m3 insulation on the rear of the

sheeting facing towards the car stacking area.

TOP half fixed panel

1

Bottom half like panel lift or vertia panel moves upand down

Figure 11-2: Indicative extent of vertical cladding area

In principle the way the cladding is intended to work is that the side facing the carpark entry (Side A) is fixed into position. i.e. it does not need to open or close

The second side side B would be fixed at the upper half while the lower level would be like a carpark panelised entry door which will lift up in front of the upper top panel to enable cars to enter and exit the parking area.

We note the approach provides sufficient comfort that the system will comply with the criteria. Like any plant and equipment design if a system can be treated or reduced

at the source then some or all of the proposed cladding may not be required but would be confirmed with onsite testing like any project that we are involved on. In any case in our opinion the development and proposed ameliorative treatment provide sufficient detail at this time to provide Council with enough comfort that the development can adequately address noise emissions.

If you have any further queries or concerns I am happy to discuss further. We note that for comparative purposes the treatment proposed in our opinion is more than sufficient to address noise emissions and retain Council's requirement to ensure the capark entry doors are not solid imperforate doors.

Regards
