GLOSSARY OF ACOUSTIC TERMS
Most environments are affected by environmental noise which continuously varies, largely as a result of road
traffic. To describe the overall noise environment, a number of noise descriptors have been developed and
these involve statistical and other analysis of the varying noise over sampling periods, typically taken as 15
minutes. These descriptors, which are demonstrated in the graph below, are here defined.
Maximum Noise Level (LAmax) – The maximum noise level over a sample period is the maximum level,
measured on fast response, during the sample period.
LA1 – The LA1 level is the noise level which is exceeded for 1% of the sample period. During the sample
period, the noise level is below the LA1 level for 99% of the time.
LA10 – The LA10 level is the noise level which is exceeded for 10% of the sample period. During the sample
period, the noise level is below the LA10 level for 90% of the time. The LA10 is a common noise descriptor
for environmental noise and road traffic noise.
LA90 – The LA90 level is the noise level which is exceeded for 90% of the sample period. During the sample
period, the noise level is below the LA90 level for 10% of the time. This measure is commonly referred to as
the background noise level.
LAeq – The equivalent continuous sound level (LAeq) is the energy average of the varying noise over the
sample period and is equivalent to the level of a constant noise which contains the same energy as the
varying noise environment. This measure is also a common measure of environmental noise and road traffic
noise.
ABL – The Assessment Background Level is the single figure background level representing each assessment
period (daytime, evening and night time) for each day. It is determined by calculating the 10th percentile
(lowest 10th percent) background level (LA90) for each period.
RBL – The Rating Background Level for each period is the median value of the ABL values for the period
over all of the days measured. There is therefore an RBL value for each period – daytime, evening and
night time.

COMMERCIAL DEVELOPMENT NOISE AND VIBRATION ASSESMENT REPORT NO. 16315 VERSION A
1 INTRODUCTION
Goodman Limited seeks approval for a staged development at 85 & 97 Waterloo Road, Macquarie
Park under Section 83B of the EP&A Act 1979.
Approval is sought for a Concept Plan and Stage 1 development, as follows:
The Concept Plan involves the redevelopment of the entire site (85 & 97 Waterloo Road)
for the purpose of commercial and retail land uses, building envelopes, landscaping,
pedestrian link, car parking, and associated infrastructure; and
The Stage 1 development includes the construction of an 11-13 storey commercial office
building including four split level basements and an adjoining road within the rear north
eastern part of the 97 Waterloo Road site.
Based on the available information, Wilkinson Murray Pty Limited (WM) has undertaken a
preliminary construction and operational noise and vibration assessment in relation to the
proposal.
This report addresses the Concept Plan and the Stage 1 developments independently, with
reference to the Ryde City Development Control Plan for the Macquarie Park corridor (the DCP)
and the relevant NSW policy and guidelines.

4 PROJECT NOISE & VIBRATION CRITERIA
4.1 Operational Noise Criteria
4.1.1 Ryde City Council – Acoustic Requirements
In relation to operational noise, the objectives of the Ryde City Council Development Control Plan
(DCP) are that:
The impacts of noise and vibration on residential development are to be mitigated
through appropriate design and the use of insulation; and
The operation of commercial and industrial developments is to protect the amenity of
residential and public spaces.
The following controls are required by the DCP:
a. An Acoustic Impact Assessment report prepared by a suitably qualified acoustic
consultant is required to be submitted with all development applications for commercial,
industrial, retail and community buildings, with the exception of applications minor
building alterations;
b. Development is to comply with all relevant statutory regulations;
c. Where light industrial and commercial development adjoins residential development,
the use of mechanical plant equipment and building services will be restricted and must
have appropriate acoustic insulation;
85 & 97 WATERLOO ROAD
COMMERCIAL DEVELOPMENT NOISE AND VIBRATION ASSESMENT REPORT NO. 16315 VERSION A
d. Loading and unloading facilities must not be located immediately adjacent to
residential development;
e. Retail premises must limit any spruiking and the playing of amplified music or messages
so as not to disturb the amenity of other public and private places; and
f. Air conditioning ducts shall not be situated immediately adjacent to residential
development.
This report principally addresses Clauses a and b. With respect to this proposal, Clauses c, d and
f are not of particular relevance as the proposed development is not located in the vicinity of any
residential properties.
The Ryde City Council Development Control Plan refers to state policy for the management of
noise emissions from any proposed development or activity within the council area. The
protection of acoustic amenity due to noise from industrial premises in NSW is managed in
accordance with the provisions of the NSW Industrial Noise Policy (INP).
4.1.2 NSW Industrial Noise Policy
The INP provides the framework for deriving noise limits for consents and licences that enables
the EPA to regulate premises that are scheduled under the Protection of the Environment
Operations Act 1997 (POEO Act). This policy seeks to promote environmental wellbeing through
preventing and minimising noise.
Section 1.1 of the INP states the specific policy objectives:
To establish noise criteria that would protect the community from excessive intrusive
noise and preserve amenity for specific land uses;
To use the criteria as the basis for deriving Project-specific noise levels;
To promote uniform methods to estimate and measure noise impacts, including a
procedure for evaluating meteorological effects;
To outline a range of mitigation measures that could be used to minimise noise impacts;
To provide a formal process to guide the determination of feasible and reasonable noise
limits for consents or licences that reconcile noise and vibration impacts with the
economic, social and environmental considerations of industrial development; and
To carry out functions relating to the prevention, minimisation and control of noise from
premises licenced under the POEO Act.
The policy sets out two noise criteria to assess the potential noise impacts resulting from industrial
activity. The first is used to control short-term intrusive noise and its impacts on residences whilst
the second is used to maintain noise level amenity for particular land uses including residences.
85 & 97 WATERLOO ROAD
COMMERCIAL DEVELOPMENT NOISE AND VIBRATION ASSESMENT REPORT NO. 16315 VERSION A
Intrusiveness Noise Impacts
The intrusiveness criterion is summarised as follows:
LAeq,15 minute ≤ rating background level (RBL, LA90) + 5dBA
o LAeq,15minute represents the equivalent continuous A-weighted sound pressure level of
the source over 15 minutes, unless other descriptors are specified as more
appropriate to characterise the source; and
o Intrusiveness noise impacts are assessed at the most affected point on or within the
residential property boundary or if that is more than 30 m from the residence, then
at the most affected point within 30 m of the residence.
Protecting Noise Amenity
The amenity criteria set limits on the total noise level from all industrial noise sources affecting a
receiver. Different amenity criteria apply for different types of receivers (e.g. residential,
commercial, industrial) and different areas (e.g. urban, suburban, rural).
The subject site is located in an area recognised as urban, in terms of the receiver classifications
identified by the INP.
With consideration to the background noise levels set out in Table 3-1, Table 4.1 sets out the
nominated noise criteria applicable to the operation of the Project, based on the provisions of the
INP, as applicable to residential and commercial receivers located in urban areas. The amenity
criteria apply to cumulative industrial noise and not only the industrial noise contribution under
assessment.

In assessing noise levels at residences or commercial receivers, the noise level is to be assessed
at the most affected point on or within the property boundary. The commercial criteria are
applicable only when such sites are in use (i.e. generally during business hours).

COMMERCIAL DEVELOPMENT NOISE AND VIBRATION ASSESMENT REPORT NO. 16315 VERSION A
4.2 Off-Site Traffic Noise Criteria
Criteria for off-site road traffic noise are specified in the NSW Road Noise Policy (RNP). The relevant criteria are summarised in Table 4-2. The identified criteria do not apply to vehicle movements within the Site. For the purpose of
assessment, any noise generated by on-site vehicle movements is considered as industrial noise
and assessed holistically with on-site fixed and mobile plant in accordance with the INP.

LAeq,9 hour 55
(external)
Additionally, where the above criteria are already exceeded the RNP identifies that for “existing
residences and other sensitive land uses affected by additional traffic on existing roads generated
by land use developments”, any increase in the total traffic noise level should be limited to 2dB
above the corresponding road traffic noise levels, due to general traffic growth, that would have
occurred if the project had not proceeded. A 2dB increase is typically considered unnoticeable.
4.3 Construction Noise Criteria
4.3.1 NSW Interim Construction Noise Guideline
The noise criteria set out in the NSW Interim Construction Noise Guideline (ICNG) are considered
in the assessment of potential impacts from construction noise. This document guides the EPA
in setting statutory conditions in licences or other regulatory instruments for construction noise.
Tables 4-3 and 4-4 summarise the relevant construction noise criteria specified in the Guideline.

Noise affected
RBL + 10dBA
The noise affected level represents the point above which there
may be some community reaction to noise.
Where the predicted or measured LAeq,,15min is greater than
the noise affected level, the proponent should apply all
feasible and reasonable work practices to meet the noise
affected level.
The proponent should also inform all potentially impacted
residents of the nature of works to be carried out, the
expected noise levels and duration, as well as contact details.
Highly noise
affected
75dBA
The highly noise affected level represents the point above which
there may be strong community reaction to noise.
Where noise is above this level, the relevant authority
(consent, determining or regulatory) may require respite
periods by restricting the hours that the very noisy activities
can occur, taking into account:
1. times identified by the community when they are less
sensitive to noise (such as before and after school for works
near schools, or mid-morning or mid-afternoon for works
near residences;
2. if the community is prepared to accept a longer period of
construction in exchange for restrictions on construction
times.
Outside
recommended
standard hours
Noise affected
RBL + 5dB
A strong justification would typically be required for works

The proponent should apply all feasible and reasonable work
practices to meet the noise affected level.
Where all feasible and reasonable practices have been
applied and noise is more than 5dBA above the noise affected
level, the proponent should negotiate with the community.
For guidance on negotiating agreements see section 7.2.2 of
the Guideline.

consideration of the daytime background noise level identified in Table 3-1, Table 4-5 sets out
the applicable Construction Noise Management Levels.

4.3.3 Construction Traffic Noise Levels
The interim construction noise guideline does not include any criteria to assess off-site traffic
noise associated with the construction. Off-site construction traffic noise has therefore been
assessed under the NSW Road Noise Policy, as detailed in Section 4.2. Noise from traffic
associated with the proposed construction is minimised as much as practical by limitations on
construction hours and Australian Design Rules, which apply to road-registered vehicles.
4.4 Construction Vibration Criteria
When assessing vibration there are two components that require consideration:
human exposure to vibration; and
the potential for building damage from vibration.
Construction work is generally considered an intermittent source of vibration.
4.4.1 Human Exposure to Vibration
Assessing Vibration: A Technical Guideline provides guidance for assessing human exposure to
vibration. The publication is based on British Standard BS 6472:1992. Intermittent vibration is
assessed by the Vibration Dose Value (VDV) which is based on the weighted root mean quartic
(rms) acceleration in each component.
Table 4-6 sets out VDV values as specified by Assessing Vibration: A Technical Guideline.

COMMERCIAL DEVELOPMENT NOISE AND VIBRATION ASSESMENT REPORT NO. 16315 VERSION A
4.4.2 Building Damage from Vibration
There are currently no Australian Standards or guidelines to provide guidance on assessing the
potential for building damage from vibration. It is common practice to derive goal levels from
international standards.
British Standard BS 7385:1993 and German Standard DIN 4150:1999 both provide goal levels,
below which vibration is considered insufficient to cause building damage. Of these, DIN 4150 is
the more stringent. DIN 4150 bases the goal levels on the highest vibration level in each
component (Peak Component Particle Velocity – PCPV). Table 4-7 summarises the goal levels
specified in DIN 4150.
Table 4-7 Guideline Values for Vibration Velocity to be used when Evaluating the
Effects of Short-Term Vibration on Structures (DIN 4150-3:1999)

Structures that, because of their particular
sensitivity to vibration, cannot be classified
under either of the other classifications and of
great intrinsic value
3 3 to 8 8 to 10
With regard to these levels DIN 4150 states, “experience has shown that if these values are
complied with, damage that reduces the serviceability of the building will not occur. If damage
nevertheless occurs, it is to be assumed that other causes are responsible. Exceeding [these]
values does not necessarily lead to damage; should they be significantly exceeded, however,
further investigations are necessary.”
For general construction vibration, the dominant frequency of vibration is typically greater than
50 Hz. However, because the dominant frequency of vibration cannot be determined with
certainty at this stage, this assessment has adopted conservative goals of 5 mm/s for residential
buildings and 20 mm/s for industrial buildings.

5 CONCEPT MASTER PLAN
The Concept Plan involves the redevelopment of the entire site (85 & 97 Waterloo Road) for the
purpose of commercial and retail land uses, building envelopes, landscaping, pedestrian link, car
parking, and associated infrastructure.
5.1 Operational Noise Assessment
The principal operational noise emissions from the site would be from on-site vehicle movements
and mechanical services.
Considering their setback distance, there is no risk of operational noise impacts at the closest
residences.
Individual mechanical plant items would be specified (or otherwise acoustically treated) to ensure
that cumulatively mechanical plant noise would comply with the 65dBA commercial noise criteria
at the closest neighbouring commercial sites.
5.2 Off-Site Traffic Noise Assessment
Traffic generation estimates, provided by the Project’s Traffic Engineers are set out in Table 5-1.

Based on these volumes, the traffic generated by this development would not be expected to
generate any material increase in off-site traffic noise levels. Traffic noise levels on Waterloo
Road would be expected to be well within the 2dB relative increase criteria.
85 & 97 WATERLOO ROAD
COMMERCIAL DEVELOPMENT NOISE AND VIBRATION ASSESMENT REPORT NO. 16315 VERSION A
5.3 On-Site Traffic Noise Intrusion Assessment
All buildings included in the master plan will be exposed to external traffic noise. The two existing
buildings on Waterloo Road will be exposed to existing traffic levels from Waterloo Road and
Khartoum Road including any predicted increase.
AS NZS 2107.2016 gives internal noise levels for different space usage for the following relevant
usages of office buildings.
Table 5-2 Internal Sound Design Levels
Usage Design Sound Level (LAeq, peroid dBA)
Board and conference Rooms 30-40
Corridors and Lobbies 45-50
General Office areas 40-45
Reception areas 40-45
At detailed design stage, appropriate glazing will be included for all final designs to ensure that
internal levels meet the above internal design levels.
5.4 Construction Noise & Vibration Assessment
Construction noise would be generated principally during:
Demolition of the internal fittings and facades of the existing structure;
Renovation of the existing buildings; and
Landscaping works.
The staging of construction works is unknown at this point in the project. This report may be
updated to reflect planned construction works, once this information is available.
It is noted that the closest residents are located at 16 Cottonwood Crescent and are approximately
190m from the closest point of the site and therefore are unlikely to be impacted by construction
noise or vibration.
Potential impacts on existing commercial uses would be minimised as much as practicable and
relevant control measures will be set out in a construction noise and vibration management plan.

6 STAGE 1- 97 WATERLOO ROAD AND DCP ROAD 1
Stage 1 of the development includes the construction of an 11-13 storey commercial office
building with four basement levels of car parking and an adjoining road. The proposed site and
associated road is shown in yellow shading in Figure 4-1.
The adjoining road construction is to form part of “Road 1” as outlined in Section 4.5. of the DCP.
Road 1 is indicated in Figure 4.2.

6.1 Operational Noise Assessment
The principal operational noise emissions from the site would be from on-site vehicle movements
and mechanical services.
The mechanical plant and services for the building would be located on the roof of the new
structure, the ground floor and in the basement. Plant specification is yet to be undertaken,
however, detailed design would ensure that all plant would be specified and/or screened by walls
or barriers to ensure INP criteria are met.
The car parking areas for the new structure are proposed to be below ground level, which will
limit carpark noise impacts.
Considering their setback distance, there is no risk of operational noise impacts at the closest
residences. Being behind the existing buildings the new structure, residential receivers would be
afforded substantial inherent shielding from the Stage 1 development.
6.2 Off-Site Traffic Noise Assessment
Traffic generation estimates, provided by the Project’s Traffic Engineers are set out in Table 6-1.

Based on these volumes, the traffic generated by this development would not be expected to
generate any material increase in off-site traffic noise levels. Traffic noise levels on Waterloo
Road would be expected to be well within the 2dB relative increase criteria.
Traffic noise levels of up to approximately LAeq 65dBA may be expected at the façade of the
neighbouring commercial premises 40m away. Acceptable internal levels are expected at the
neighbouring building, given its fixed closed windows and substantial glazing standard.
85 & 97 WATERLOO ROAD
COMMERCIAL DEVELOPMENT NOISE AND VIBRATION ASSESMENT REPORT NO. 16315 VERSION A
6.3 On-Site Traffic Noise Intrusion Assessment
The stage one commercial building will be exposed to the traffic noise generated by the new
road. Appropriate glazing will be specified during detailed design to ensure internal noise levels
do not exceed the levels recommended by AS NZS 2107, as set out in Table 6-2.
Table 6-2 Internal Sound Design Levels
Usage Design Sound Level (LAeq dBA)
Board and conference Rooms 30-40

Reception areas 40-45
Typical commercial buildings will have fixed closed windows and substantial a glazing standard
by design. A typical commercial building such as this would readily achieve acceptable internal
levels.
6.4 Construction Noise & Vibration Assessment
Construction noise would be generated principally during:
The construction of the 11-13 storey building; and
The construction of the road along the north-east boundary.
The staging of construction works is unknown at this point in the project. This report may be
updated to reflect planned construction works, once this information is available.
It is noted that the closest residents are located at 16 Cottonwood Crescent and are approximately
190m from the closest point of the site and therefore are unlikely to be impacted by construction
noise or vibration.
Potential impacts on existing commercial uses would be minimised as much as practicable and
relevant control measures will be set out in a construction noise and vibration management plan.

7 CONCLUSION
Based on available information, Wilkinson Murray has conducted a preliminary noise and vibration
assessment for the proposed Concept Plan and Stage 1 developments at 85 & 97 Waterloo Road,
Macquarie Park.
This assessment has considered operational noise assessment (i.e. potential noise impacts on the
surrounding receivers due to the operation of the proposed uses); off-site traffic noise (i.e. traffic
noise generated by the development); traffic noise intrusion (with respect to impacts on future
occupants of the proposed uses); and construction noise and vibration.
This assessment has determined that, subject to further detailed design, the proposed
developments would be expected to meet the relevant noise and vibration standards.
The proposed developments are considered to present a minimal risk in terms of noise and
vibration impact potential.
Minimum glazing standards and any necessary requirements for the control of mechanical
services noise will be confirmed during detailed design and this report may be updated to reflect
the final design.
