INTRODUCTION
This Acoustic Report has been prepared for The Belgrave Group of Companies for the development of 375 - 377 Punt
Road — Cremorne and represents the proposed Acoustic Services.
This Acoustic Report sets out the acoustic performance requirements for the project. The design criteria presented in
this report are based upon relevant Australian Standards and Wood & Grieve Engineers previous experience and have
been benchmarked against other similar projects.
Included in this report are the key acoustic considerations that form the basis of the acoustic design for the project
including:
Noise intrusion from external noise sources
Airborne sound insulation requirements
Impact sound insulation requirements
Background noise levels generated by mechanical services within the different spaces
The acoustic terms used in this report are explained in Appendix 1.

PROJECT OVERVIEW

375 - 377 PUNT ROAD CREMORNE
DESIGN CRITERIA
In general noise from industrial and commercial facilities must comply with the requirements of the Victorian EPA State
Environmental Protection Policy No. N-1 (SEPP N-1), which applies noise limits at noise sensitive locations such as
residential areas.
For this project, design measures to protect the residential areas from existing noise sources in the area of the
development will be implemented as part of the design of the new development, rather than the existing commercial
and industrial facilities being required to comply with the SEPP N-1 noise limits.
The following sections outline acoustic design criteria for this project, for noise emission from the development to noise
sensitive areas, and noise intrusion to the noise sensitive areas of the development.
ENVIRONMENTAL NOISE LIMITS
4.1
The Victorian Environmental Protection Agency (EPA) State Environmental Protection Policy No. N-1 (SEPP n-1)
prescribes procedures for determining the statutory environmental noise limits which apply at noise sensitive locations,
such as residential areas, with respect due to commercial, industrial and trade operations.
Generally it is accepted that noise from mechanical plant and building services that may affect noise sensitive receivers
be assessed under SEPP N-1 criteria, therefore the SEPP N-1 criteria will apply to those noise emissions from the
mechanical services of the development on the nearest sensitive receivers.
The SEPP N-1 noise limits are dependent on:
•
Zoning levels, which are based on the planning scheme zoning types within 70-metre and 200-metre radii of
the noise sensitive area.
•
The time of day i.e. different limits apply at different times of the day.
•
The background noise level (LA90) in the noise sensitive area, in the absence of noise due to commercial,
industrial or trade operations.
Under SEPP N-1, noise from the source under consideration is measured so as to determine its impact over a
continuous period. Adjustments to the measured noise level are applied to account for the effects of duration, tonality,
intermittency and impulsiveness.
4.1.1
SEPP N-1 TIME PERIODS
The following time period classifications are defined by SEPP N-1:
Table 1: SEPP N-1 Time Period Classification

6pm to 7am Weekends and Public Holidays
NOISE SURVEY
According to the EPA Guidelines an environmental background noise survey is required. As time constraints do not
permit for a survey to be conducted at this time a conservative assessment using SEPP N-1 and AS1055.2 recommended
levels has been used.

SEPP N-1 TYPICAL NOISE LIMITS
4.3
The Victorian EPA Publication 1412 SEPP N-1 and NIRV Explanatory Notes, October 2011, provides examples of typical
SEPP N-1 noise limits for various land uses in lieu of recorded noise data. These can be adopted for conservative
assessments as a reference to assist investigations.
The typical noise limits under SEPP N-1 are listed in Table 2 below:

AS1055.2 ESTIMATED AVERAGE BACKGROUND LEVELS
4.4
AS1055.2 Acoustics — Description and measurement of environmental noise, July 1997, provides estimated average
background a-weighted sound pressure levels (LA90j) for different areas containing residences in Australia. In lieu of
actual recorded data the levels in Table 3 below will be used to inform the noise criteria in this assessment.

NOISE LIMITS CALCULATED FOR THIS SITE
4.5
Based on our site assessment work it is appropriate to apply the assessment methods described by the SEPP N-1 policy
at this site. Accordingly, the noise level limits are calculated for each residence location individually and take account of
the following factors.
•
The time of day (day, evening or night).
•
The proportions of land zoned for residential, industrial and commercial use in the immediate local area.
•
The background noise level, which would occur at the residence if activities associated with the commercial
premises were not occurring.
The permissible noise levels have been determined based adopted background noise levels derived from AS1055.2 and
current land use zoning information obtained from the Department of Planning and Community Development. Zoning
maps showing the extent of the 70m radius & 200m radius circles are shown in Figures 3 & 4.

elements to the doors, walls and facades.
The noise from traffic and trains alone will provide significant affect to the building. The facade elements of the building
are to be suitably designed so that these noises do not affect the amenity of the residents.
INTERNAL NOISE LEVELS
4.7
The internal noise levels for spaces presented in the proposed development are affected by a number of factors
including:
•
Road traffic noise entering via the building facade;
•
Noise from building services units, internal and external
•
Operational noise
•
Noise from trains & trams
The Australian Standard AS/NZS 2107:2000 — 'Acoustics- Recommended design sound levels and reverberation times for
building interiors' specifies target noise levels and reverberation times for internal spaces and values corresponding to
the relevant types of spaces are summarised below in Table 5.

DESIGN CRITERIA 10
3 7 5 - 3 7 7 PUNT ROAD CREMORNE
DESIGN REQUIREMENTS
Residential developments (being Class 2, 3 or 9c) must comply with the requirements of Part F5 of the NCC 2014 to
provide adequate sound isolation between sole-occupancy units.
This acoustic specification details the acoustic requirements and recommended treatments for the proposed
development. The recommended treatments provide a guide to suitable building constructions which will achieve
acoustic compliance with the NCC 2014.
The main acoustic issues addressed in this specification are:
control of air and structure borne noise transfer in critical parts of the development
•
•
control of services noise.
5.1
Building Code of Australia [Class 2]
184 Ferguson Street is classified as a Class 2 building under Part A3 of the NCC 2014.
Class 2 buildings are buildings which contain two or more sole-occupancy units, each being a separated dwelling. Class 2
buildings must achieve the objectives outlined in Part FS of the NCC 2014 Sound Transmission and insulation.
5.1.1
Part F5.4 Sound insulation rating of floors
The recommended floor ceiling separations for Class 2 buildings are shown in Table 6.

DESIGN REQUIREMENTS 11
375 - 377 PUNT ROAD CREMORNE
Note: (1) Discontinuous construction is defined such that walls are to have a minimum 20 mm gap between separate
leaves. Cavity masonry walls are to have resilient wall ties or no wall ties. For other walls there are to be no mechanical
linkages between wall leaves except at the wall periphery. A staggered stud wall is not deemed to be discontinuous.
For quality apartments, an Rw 60 is desirable for addressing low frequency noise ingress. This requires either mass
(masonry or concrete) to be included in the design, or a significant airgap with lightweight construction to give a plan
thickness greater than 200 mm.
A wall which is required to have sound insulation must continue to:
•
the underside of the slab or roof above, or
•
a ceiling that provides the sound insulation required for the wall.
5.1.3
Part F5.6 Sound insulation rating of services
The noise isolation rating for waste pipes, soil pipes, rainwater pipes and water supply pipes and ducts is outlined in
Table 8.
Table 8 NCC 2014 ceiling/riser bulkhead separation barriers requirements
A duct, soil, waste, water supply pipe and stormwater pipe that is located
in a wall or floor cavity, serves or passes through more than one soleoccupancy unit:
(a) if the adjacent room is a habitable room (other than a kitchen); or
Rw Ctr. 40
(b) if the room is a kitchen or any other room.
Rw +Ctr _>_.25
Services must not be chased into concrete or masonry elements.
When installed in a wall separating sole-occupancy units, a water supply pipe must:
•
Only be installed in the cavity of a discontinuous construction. Discontinuous construction is defined such that
walls are to have a minimum 20 mm gap between separate leaves. Cavity masonry walls are to have resilient wall
ties or no wall ties. For other walls there are to be no mechanical linkages between wall leaves except at the wall
periphery. A staggered stud wall is not deemed to be discontinuous.
•
In the case of a pipe that serves only one sole-occupancy unit, not to be fixed to the wall leaf on the side adjoining
any other sole-occupancy unit and have a clearance not less than 10 mm to the other wall leaf.
5.1.4
Part F5.5 Sound insulation of pumps
A flexible coupling must be used at the point of connection between the service pipes in a building and any circulating
or other pump.
