MB247-01F03 (REV 0) STATEMENT OF EVIDENCE.DOCX TRUGANINA PSP 1090

1. My name is Robin Brown and I am an Associate Director at Renzo Tonin & Associates (VIC) Pty

Ltd, consultants in acoustics, vibration and structural dynamics. The business operates from

premises at Suite 218 / 87 Gladstone Street, South Melbourne.

2. I hold a Bachelor of Engineering (Honours) from Auckland University and I have practiced as a

consulting engineer in acoustics for 10 years. I am a member of the professional societies listed

in my curriculum vitae as presented in Appendix A.

3. The majority of my experience relates to the assessment of noise and the specification of

mitigation strategies for achieving compliance with applicable criteria.

4. I am retained by Leakes Pty Ltd and instructed by Minter Ellison to provide an acoustic

assessment of noise impacts on the proposed subdivision on the Davis Property on Derrimut

Road (the Subject Land) in accordance with clause 4.0 of Design Development Overlay –

Schedule 10 (DDO10).

5. I have been provided with the following documents:

- Instructions from Minter Ellison dated 13 November 2013

- Davis Property Development Plan, Spiire drawing 136345P68, version 7, 31 October

2013

- Schedule 10 to the Design and Development Overlay (DDO10)

- Regional Rail Link Authority document Update to Noise Impact Management Report

dated the 8th of March 2013 (UNIMR)

6. Noise modelling has been carried out by Mr Timothy Mawson under my supervision.

7. I confirm that this expert witness document has been prepared in accordance with Planning

Panels Victoria document Guide to Expert Evidence and that my evidence in this statement is

within my area of expertise.

8. The details of my assessment and resulting recommendations are contained within Renzo Tonin

& Associates document MB247-01F02 (rev 1) Acoustic report, dated 17 November 2013 (the

RTA report), refer to Appendix B.

9. I have identified two potentially practicable scenarios for satisfying the requirements of DDO10:

i. Implementation of architectural noise attenuation treatments

ii. Implementation of noise wall treatments

10. Implementation of architectural treatments requires the facades of all affected bedrooms as

shown in Figure P02 of Appendix E of the RTA report to be upgraded.


MINTER ELLISON



11. Of the 124 houses in the northern subdivision within the DDO10 boundary, approximately 56

may require architectural treatments to bedrooms.

12. Of the 201 houses in the southern subdivision within the DDO10 boundary, approximately 95


13. In general this upgrade involves the installation of laminated glazing and attenuated

mechanical ventilation.

14. The number of buildings requiring architectural noise attenuation treatments is minimised if the

first row of houses adjacent to the rail corridor is constructed before those houses behind. This

first row of houses would act as a noise wall to dwellings constructed behind.

15. Within the context of a low density residential subdivision it would not be possible to

significantly reduce the number of affected properties by amending the layout without

changing the usage of the land adjacent to the corridor (for example rezoning for a 100 to

150m wide strip of parkland either side of the corridor).

16. The noise wall scenario assumes that noise walls are constructed on and near the boundary of

the Regional Rail Link Authority’s (future VicTrack) land (as per Figure P04 of the RTA Report).

17. Resulting noise impacts under this scenario are shown in Figure P03 of the RTA Report. The key

outcome being that no dwellings require architectural treatment.

18. Unlike the architectural approach, I note that the noise wall scenario has the added benefit of

reducing both external noise levels and noise levels within areas other than bedrooms.

19. I am of the opinion that no changes are required to the layout on the s96A subdivision plans to

satisfy the requirements of DDO10.

20. I have made all the inquiries that I believe are desirable and appropriate and no matters of

significance which I regard as relevant have to my knowledge been withheld from the Panel.

Signed and dated

Robin Brown

1 Introduction

Amendment C175 seeks to implement the Truganina PSP into the Wyndham Planning Scheme, and also

to approve planning permits for subdivision of the Leakes/Davis land (north and south) pursuant to

section 96A of the Planning and Environment Acoustic 1987 (Vic). Wyndham Design and Development

Overlay – Schedule 10 (DDO10) was gazetted in November 2013 to address noise issues related to the

Regional Rail Link Section 2 (RRL2). Renzo Tonin & Associates was engaged by Leakes Pty Ltd to provide

an acoustic assessment of noise impacts on the proposed Davis/Leakes land subdivision and provide

recommendations for noise attenuation measures with regard to clause 4.0 of DDO10.

The plan of subdivision consists of two parcels of land bound by Skeleton Creek to the west. The larger

parcel is to the north of the RRL2 corridor is bound by Dohertys Road to the north and the Melbourne

Water Forsyth Drainage reserve to the east. Whilst the smaller parcel of land to the south of the RRL2

corridor is bound by Leakes Road to the south and Woods Road to the east.

- Refer to Appendix C for the development plan

The work documented in this report was carried out in accordance with the Renzo Tonin & Associates

Quality Assurance System, which is based on Australian Standard / NZS ISO 9001. Appendix A contains a

glossary of acoustic terms used in this report.


LEAKES PTY LTD



2 Applicable Criteria

2.1 The Minister for Planning’s Directions

On the 28th of March 2012 the Minister for Planning issued a document entitled Minister’s Directions

for Operational Noise Response – Regional Rail Link Section 2 (the Minister’s Directions). This document

includes the following direction to GAA, Wyndham City Council and Melton Shire Council:

“A Design and Development Overlay (DDO) is to be developed for areas zoned for noise sensitive uses

adjoining the rail corridor for the purpose of requiring the adoption of building designs and architectural

treatments to limit internal noise levels in bedrooms to less than 65dB LAmax and 40 dB LAeq, 9hr (Night)

for new developments. It is to be applied to land where either measured or modelled residual noise levels

from rail operations, in combination with road traffic, would exceed the external noise levels of 80dB

LAmax or 55 dB LAeq, 9h (night) after the installation of the most effective and practicable noise

mitigation measures.”

2.2 Design & Development Overlay

Wyndham Design and Development Overlay – Schedule 10 (DDO10) was gazetted in November 2013. In

particular:

- Clause 3.0 of DDO10 sets out requirements for a permit to subdivide land

- Clause 4.0 of DDO10 sets out requirements for an application to subdivide land

These clauses are as below. To fulfil the requirement of Clause 4.0, assessment of noise levels on the

proposed Leakes/Davis land subdivision has been carried out with regard to the acoustic metrics set out

in Clause 3.0 (that internal bedroom noise levels shall not exceed 65 dB LAmax and 40 dB LAeq,8h for

the night period from 10pm to 6am). Consistent with the Minister’s Direction’s dwellings of standard

construction are expected to comply with the internal acoustic metrics where external noise levels are

less than 80dB LAmax and 55 dB LAeq, 9h (night).

3.0 Subdivision

Requirement

A permit to subdivide land must require a restriction on titles requiring buildings (and associated works)

for accommodation, a child care centre, a display home, a hospital, a hotel or a tavern to be constructed in

such a way as to ensure internal bedroom noise levels will not exceed 65 dB LAmax and 40 dB LAeq,8h for

the night period from 10pm to 6am. The restriction may include specific construction requirements to the

satisfaction of the responsible authority.

A permit may not be granted to subdivide land which is not in accordance with this requirement


LEAKES PTY LTD



4.0 Application requirements

An application to subdivide land or to construct a building or construct or carry out works must be

accompanied by an acoustic assessment prepared by a qualified acoustic engineer or other suitably skilled

person to the satisfaction of the responsible authority. The acoustic assessment must:

Provide an assessment of noise levels on the land taking into account the likely noise levels

associated with the ongoing operation of the Regional Rail Link.

Include recommendations for noise attenuation measures designed to achieve the internal

bedroom noise limits specified in the requirements in this schedule.

An application to subdivide land must also be accompanied by a design response that addresses the

recommendations of the acoustic assessment and minimises the number of buildings requiring

architectural noise attenuation treatments.

An application to construct, or carry out works for, an acoustic wall or other acoustic structure that is not

part of a building must also be accompanied by a plan, elevations and other suitable material prepared to

the satisfaction of the responsible authority showing:

A visually engaging design avoiding the use of a sheer wall on either side of the structure.

Landscaping along the interface area of the structure to soften its visual impact.

3 Assessment of Noise Levels

3.1 Noise Modelling

Modelling of operational rail noise was carried out implementing the Nordic prediction method

algorithms in SoundPLAN 7 proprietary modelling software utilising rail alignment data provided by

Spiire. This data was cross checked and found to be consistent with 'final design issue' plans for the

alignment as provided by Herbert Smith Freehills on or about the 24th of September 2012 (refer to

Appendix D). It is noted that rail alignment data used in the Regional Rail Link Authority document

Update to Noise Impact Management Report dated the 8th of March 2013 (UNIMR) assessment are

derived from files dated from the 5th of June 2012 (refer to Appendix C1 of the UNIMR). When

completed, the noise model was calibrated against noise contour maps presented in the UNIMR.

The Development Plan was imported into the noise model with housing modelled under the following

assumptions:

- Front facades set back 5m from property boundaries

- Rear facades set back 8m from rear boundaries

- Adjacent houses separated by 2m

The noise model was then run for the following three scenarios:

1. Subdivided land prior to any construction

2. Subdivided land on completion of construction

3. Subdivided land on completion of construction with noise walls in place

Results of the noise assessment were presented in the form of the noise contour maps contained in

Appendix E. Note that the noise model was run a number of times under scenario 3 as required to

determine the minimum noise wall heights satisfying the requirements set out in DDO10. Also note that

detail relating to the Morris Road grade separation has not yet been included in the model. Inclusion of

this detail is not expected to have a significant effect on the total number of dwellings requiring noise

attenuation.

For the purposes of this assessment compliance with LAmax criterion implies compliance with LAeq,

9hr(night) criterion. This point is demonstrated by the location of the 55dB(A) Leq and 80dB(A) Lmax

predicted noise criteria contours for year 2026 shown in Appendix D1.2 of the UNIMR (refer Appendix F

of this document), specifically the 80dB(A) reaches further outside the corridor then the 55dB(A) and

hence is the more onerous criterion.

3.2 Bedroom Noise levels

Resultant noise levels were then calculated assuming:

- a typical bedroom size of 4000mm by 4000mm


LEAKES PTY LTD



- a ceiling height of 2700mm

- glazed openings (windows, doors) of approximately 3m2 in total

- transmission loss of building elements as represented by the weighted reduction index, Rw

presented in Table 1 below

- overall noise levels taken from the noise modelling results

- a Diesel Multiple Unit (DMU) source spectrum taken from an LAmax measurement of Vline

‘Vlocity’ DMU operating on the Geelong Line at high speed on the evening of Thursday the

18th of April 2013


LEAKES PTY LTD



4 Recommendations for Noise Attenuation

4.1 Architectural Noise Attenuation Treatment

Referring to noise contour map, Figure P02 in Appendix E facades of bedrooms outside the coloured

areas require no special treatment as noise levels at these locations do not exceed 80dB LAmax and

55dB LAeq, 9hr(night).

Consistent with DDO10, bedrooms of properties that are exposed to maximum external noise levels

greater than 80dB(A) shall be designed such that internal noise levels are less than 65dB LAmax and

40dB LAeq, 9hr(night). No consideration is required for rooms of other type.

Table 1 sets out a schedule of typical treatments that satisfy the DDO10 requirements. This table is to be

read in conjunction with Figure P02 which shows noise levels reducing with distance from the corridor.

Facades of bedrooms affected by the blue noise contour range required less onerous treatment than

facades within the red noise contour range. A zoom-in showing noise propagation across a typical

section of lots adjacent to the rail corridor is presented in Figure P05.

Significant variation from the assumed typical bedroom attributes described above may trigger a need

for more onerous construction, such as thicker glazing or façade construction having greater surface

density.

4.2 Noise Wall Treatment

Figure P03 in Appendix E shows noise contours resulting from the implementation of the optimised

noise walls. The noise contour map shows that no houses require architectural noise attenuation

treatment as all properties are outside the coloured noise contours. This scenario assumes that noise

walls ranging in height from 2.5 to 4.0 meters are constructed within the rail corridor (future VicTrack

land), adjacent to the boundary with adjoining land as shown in Figure P04 of Appendix E.


LEAKES PTY LTD



5 Conclusion

Renzo Tonin & Associates has completed an acoustic assessment of noise impacts on the proposed

Davis/Leakes land subdivision and developed recommendations for noise attenuation measures to

satisfy the requirements DDO10. In particular two potentially practicable approaches to satisfying the

requirements have been identified:

1. Implementation of architectural noise attenuation treatments

2. Implementation of noise wall treatments

Implementation of architectural treatments requires upgrade of the facades of all affected bedrooms as

shown in Figure P02 of Appendix E. 11. Key outcomes of this strategy are that:

- of the 124 houses in the northern subdivision within the DDO10 boundary, approximately 56


- of the 201 houses in the southern subdivision within the DDO10 boundary, approximately 95


Implementation of noise walls on, and proximate to the boundary of the rail reserve (future VicTrack

land) as shown in Figure P04 results in an outcome by which no dwellings require architectural

treatment.

APPENDIX A Glossary of Terminology

The following is a brief description of the technical terms used to describe noise to assist in

understanding the technical issues presented.

Adverse Weather Weather effects that enhance noise (that is, wind and temperature inversions) that occur at a site

for a significant period of time (that is, wind occurring more than 30% of the time in any

assessment period in any season and/or temperature inversions occurring more than 30% of the

nights in winter).

Ambient Noise The all-encompassing noise associated within a given environment at a given time, usually

composed of sound from all sources near and far.

Assessment Period The period in a day over which assessments are made.

Assessment Point A point at which noise measurements are taken or estimated. A point at which noise

measurements are taken or estimated.

Background Noise Background noise is the term used to describe the underlying level of noise present in the ambient

noise, measured in the absence of the noise under investigation, when extraneous noise is

removed. It is described as the average of the minimum noise levels measured on a sound level

meter and is measured statistically as the A-weighted noise level exceeded for ninety percent of a

sample period. This is represented as the L90 noise level (see below).

Decibel [dB] The units that sound is measured in. The following are examples of the decibel readings of every

day sounds:

0dB The faintest sound we can hear

30dB A quiet library or in a quiet location in the country

45dB Typical office space. Ambience in the city at night

60dB CBD mall at lunch time

70dB The sound of a car passing on the street

80dB Loud music played at home

90dB The sound of a truck passing on the street

100dBThe sound of a rock band

115dBLimit of sound permitted in industry

120dBDeafening

dB(A) A-weighted decibels. The ear is not as effective in hearing low frequency sounds as it is hearing

high frequency sounds. That is, low frequency sounds of the same dB level are not heard as loud

as high frequency sounds. The sound level meter replicates the human response of the ear by

using an electronic filter which is called the “A” filter. A sound level measured with this filter

switched on is denoted as dB(A). Practically all noise is measured using the A filter.

Frequency Frequency is synonymous to pitch. Sounds have a pitch which is peculiar to the nature of the

sound generator. For example, the sound of a tiny bell has a high pitch and the sound of a bass

drum has a low pitch. Frequency or pitch can be measured on a scale in units of Hertz or Hz.

Impulsive noise Having a high peak of short duration or a sequence of such peaks. A sequence of impulses in

rapid succession is termed repetitive impulsive noise.

Intermittent noise The level suddenly drops to that of the background noise several times during the period of

observation. The time during which the noise remains at levels different from that of the ambient

is one second or more.

LMax The maximum sound pressure level measured over a given period.

LMin The minimum sound pressure level measured over a given period.

L1 The sound pressure level that is exceeded for 1% of the time for which the given sound is

measured.

L10 The sound pressure level that is exceeded for 10% of the time for which the given sound is

measured.


LEAKES PTY LTD



L90 The level of noise exceeded for 90% of the time. The bottom 10% of the sample is the L90 noise

level expressed in units of dB(A).

Leq The “equivalent noise level” is the summation of noise events and integrated over a selected period

of time.

Reflection Sound wave changed in direction of propagation due to a solid object obscuring its path.

SEL Sound Exposure Level (SEL) is the constant sound level which, if maintained for a period of 1

second would have the same acoustic energy as the measured noise event. SEL noise

measurements are useful as they can be converted to obtain Leq sound levels over any period of

time and can be used for predicting noise at various locations.

Sound A fluctuation of air pressure which is propagated as a wave through air.

Sound Absorption The ability of a material to absorb sound energy through its conversion into thermal energy.

Sound Level Meter An instrument consisting of a microphone, amplifier and indicating device, having a declared

performance and designed to measure sound pressure levels.

Sound Pressure Level The level of noise, usually expressed in decibels, as measured by a standard sound level meter with

a microphone.

Sound Power Level Ten times the logarithm to the base 10 of the ratio of the sound power of the source to the

reference sound power.

Tonal noise Containing a prominent frequency and characterised by a definite pitch.
