Noise and Vibration CEMP Sub-plan Advisian 2 of 42
Synopsis
The Noise and Vibration Construction Environmental Management Plan (CEMP) Sub-plan has been
prepared by Advisian to identify environmental risks associated with noise and vibration and how
those identified risks will be managed and mitigated for Stage 2 construction activities for the Eden
Breakwater Wharf Extension herein referred to as Stage 2 of “the Project”. The Project is to be
carried out by NSW Department of Industry (the Principal).
Specifically, the Noise and Vibration CEMP Sub-plan has been prepared to address the
requirements of Conditions C3b and C4 of the Infrastructure Approval (SSI 7734) and details how
the performance outcomes, commitments and mitigation measures specified in the Environmental
Impact Statement (EIS) and Response to Submissions (RTS) Report prepared during the planning
approval stage of the Project, as well as the relevant terms of the Infrastructure Approval, will be
implemented and achieved during construction. In accordance with Condition C17, the
requirements of the Noise Construction Monitoring Program in Condition C10a, C11, C12 and C13
have been incorporated into this Sub-plan.

1 Introduction
1.1 Purpose and Objectives of the Sub-plan
Advisian has prepared a Construction Environmental Management Plan (CEMP) to identify the
environmental risks and detail how those identified risks will be managed and mitigated for all
construction activities for the Eden Breakwater Wharf Extension herein referred to as “the Project”.
The CEMP also addresses the relevant requirements of the Infrastructure Approval and other
applicable approvals and permits.
This Noise and Vibration CEMP Sub-plan has been prepared by Advisian to address the
requirements of Conditions C3b and C4 of the Infrastructure Approval (State Significant
Infrastructure (SSI) Approval No 7734) and detail how the performance outcomes, commitments
and mitigation measures specified in the Environmental Impact Statement (EIS) and Response to
Submissions (RTS) Report prepared during the planning approval stage of the Project, as well as
the relevant conditions of the Infrastructure Approval, will be implemented and achieved during
construction. Further, in accordance with Condition C17, the requirements of the Noise
Construction Monitoring Program in Conditions C10a, C11, C12 and C13 have been incorporated
into this Sub-plan.
Construction of the Project will be delivered in two stages under two separate contracts by a
Dredging Contractor (Stage 1) and a Marine Structures Contractor (Stage 2). The two Contractor’s
activities on-site will occur in series: that is, there will be only one Contractor on-site at any one
time. A description of the Project, including staged construction is provided in Section 1.3. This
Noise and Vibration CEMP Sub-plan applies to Stage 2 of construction and forms part of the CEMP
for the Project.
This Noise and Vibration CEMP Sub-plan has been prepared in consultation with the Bega Valley
Shire Council (BVSC), NSW Environment Protection Authority (EPA) and the Project’s Community
Consultative Committee (CCC). The details of the consultation undertaken are set out in Section 2
with copies of written correspondence between the Principal and the agencies and stakeholders
provided in Appendix A.
The objectives of this Noise and Vibration CEMP Sub-plan are to:
Ensure all Contractor(s) and Project personnel clearly understand their environmental
obligations under the relevant Project approvals, permits and licences in relation to noise and
vibration;
Enable the Project to comply with the relevant Commonwealth and State Government
requirements and all relevant Australian standards;
Describe the management/mitigation measures and requirements as detailed in the CEMP, EIS
(and as amended by the RTS Report) and all other approvals, permits and licences to ensure
noise and vibration risks are minimised to As Low As Reasonably Practicable (ALARP); and
Noise and Vibration CEMP Sub-plan Advisian 11 of 42
Detail the required Noise Monitoring Program required during construction activities relating
to Stage 2.
This Noise and Vibration CEMP Sub-plan and appended Noise Monitoring Program, have been
developed in consideration of the following relevant guidelines:
NSW Interim Construction Noise Guideline; and
Assessing Vibration: A Technical Guideline (DECC 2006).

1.3 Project Description
The Project comprises the extension of the existing Eden Breakwater Wharf and dredging of the
approach channel and berth pocket with offshore disposal, to accommodate the berthing of cruise
ships of up to 325m in length.
Key features of the Project include:
Extension of the existing wharf by approximately 95m;
Installation of three mooring dolphins and two berthing dolphins;
Installation of new landside bollards to restrain the ship’s bow;
Dredging of approximately 231,500m3 of in-situ material (including over-dredging allowance);
Transport and placement of the dredge material at an offshore disposal site;
Installation of minor services (lighting, power, potable water and emergency water); and
Installation of navigational aids.
The Eden Breakwater Wharf is located in Snug Cove, Eden, New South Wales and the offshore
disposal site is approximately 6 nautical miles offshore from Twofold Bay.
As described above, construction of the Project will be delivered in two stages (as described in the
Staging Report, Revision 0, 24 July 2017 for more detail) with only Stage 2 construction activities
the subject of this Noise and Vibration CEMP Sub-plan.
Key Stage 2 construction activities potentially leading to adverse noise and vibration impacts relate
to piling activities.
Piling to construct the new wharf deck will constitute 78 steel piles, which will be driven to a design
toe level (level into the seabed) by a piling hammer lifted by a crane mounted either on a barge or
from the existing wharf. Prefabricated headstocks will then be installed by crane onto the piles.
Rock anchors may be installed in some piles, depending on pile refusal level. Three to four piles will
Noise and Vibration CEMP Sub-plan Advisian 14 of 42
support each of the headstocks (or bents). Prefabricated concrete deck panels will then be lifted
into place, spanning across two adjacent headstocks (or bents). Once all deck panels have been
installed, gaps will be filled with a gap filler product, before an in-situ concrete topping slab is
installed and minor services are fitted to the deck.
Three mooring dolphins and two berthing dolphins will also be installed along the fender line
(berthing face). Each dolphin will consist of six steel tubular piles driven into the seabed by a piling
hammer suspended from a crane mounted on a barge. Once the piles are established, the pre-
fabricated dolphin modules will be installed with bollards on each of the decks, access platform,
safety ladders and hand railings fitted. Panel fenders will be installed on the berthing dolphins.
Onshore, three bollards will be installed, consisting of six piles per bollard. Finally, the navigational
tower will also require a single pile.
A total of 127 piles will be required and it is anticipated that piling will occur over approximately six
months.
During the installation of the piles, a vibro-hammer will be utilised at commencement of driving in
some areas. These piles will be installed to maximum achievable depth with the vibro hammer,
prior to use of the hydraulic hammer to complete the install. Due to the required pile loads, and
the expected geotechnical conditions, as well as the requirement for load testing, all piles will
require driving with a hydraulic hammer; however the extent of this will be minimized through the
use of the vibro-hammer. This approach will not be possible for all piles, due to the presence of
rock from bed level in some areas, however, this approach will be adopted wherever possible.
The key reference documents for a detailed description of the existing noise and vibration
environment are Section 9.6 of the EIS (Advisian 2016), Appendix K of the EIS – Noise, Vibration
and Air Quality Assessment and Addendum Report (PEL 2016a and PEL 2016b).
Further detail relating to the construction activities for the Project is contained within the CEMP
prepared under Conditions C1 and C2 of the Infrastructure Approval.

2 Stakeholder Consultation
BVSC, the EPA and the CCC (the then Community Liaison Group) were consulted during the
preparation of the EIS, CEMP and RTS for the Project and provided feedback during DP&E’s
assessment of the Project.
The Infrastructure Approval Part C - Construction Environmental Management, requires
preparation of a CEMP and a number of CEMP Sub-plans and Construction Monitoring Programs
to be prepared in consultation with relevant government agencies.
As required by Conditions C3 consultation regarding this Noise and Vibration CEMP Sub-plan was
undertaken by the Principal (and Contractor as relevant) with the BVSC, the EPA and CCC. As
required by C12, consultation regarding the Construction Noise Monitoring Program was
undertaken by the Principal with BVSC and the EPA. Their requests and the Principal’s response are
outlined in Table 2-1.
Table 2-1 Noise and Vibration Sub-plan Agency requests and Principal’s response
Agency Request Response
BVSC No requests received. N/A
NSW EPA Recommendation to consider a
formalised ongoing review process
of all employed noise and vibration
management and mitigation
practices throughout Stage 2, to
ensure changes in construction
activities continue to meet best
management practice and
appropriately consider impacts on
noise to sensitive receivers.
The Project has developed and
implemented a Construction
Compliance Monitoring Program, in
which regular (weekly) formal checks
are completed against commitments
and management measures. Further,
continuous noise monitoring during
piling, the implemented community
communications strategy, and the
dedicated Project Communications
Advisor will ensure that impacts to
noise sensitive receivers can be
managed effectively throughout the
Project.
CCC A member of the committee
explained that many businesses of
the Port Precinct close by 3pm, and
requested if the construction
program could be modified to
consider this.
The daily program cannot be altered
everyday to pile only after 3pm due
to the many other aspects
influencing when piling will be
scheduled that day, as it has the
potential to significantly draw out
the overall program. However, the
Contractor can commit to
accommodating businesses as much
as possible, whilst still adhering to

3 Noise and Vibration Management
3.1 Permitted Hours of Work
In accordance with Condition E9 of the Infrastructure Approval, Construction must only be
undertaken during the following standard construction hours:
a. 7:00am to 6:00pm Mondays to Fridays, inclusive; b. 8:00am to 1:00pm Saturdays; and c. At no time on Sundays or public holidays.
Except in the following circumstances:
i. For the delivery of materials required by the NSW Police Force or other authority for
safety reasons;
ii. Where it is required in an emergency to avoid injury or the loss of life, to avoid
damage or loss of property or to prevent environmental harm; and
iii. Where different construction hours are permitted or required under an EPL in force in
respect of the Construction, in which case those construction hours must be complied
with (not relevant for this Stage of work).
3.2 Traffic Noise
A road traffic assessment completed by PEL (PEL 2016a) did not identify any exceedances of
guideline noise levels due to the increase to existing traffic noise levels for day time construction
hours. Due to the above described permitted work hours, little to no construction traffic will occur
in evening and night time hours.
All regular suppliers (such as concrete truck drivers) will be required to undergo a Project-specific
truck induction to familiarise themselves with the Project’s requirements such as approved
transport routes and noise mitigation outlined in this Noise and Vibration CEMP Sub-plan.
Irregular delivery drivers will be forwarded a copy of the approved transport routes and permitted
delivery times along with their contract/purchase order.
3.3 Underwater Noise Assessment
Underwater piling noise is characterised based on the size of the pile and piling method utilised.
Table 3-1 summarises the characteristics of piling noise (PEL 2016a).
Noise and Vibration CEMP Sub-plan Advisian 18 of 42
Table 3-1 Impact Piling Noise Characteristics (source: PEL 2016a)
PEL undertook an underwater construction noise impact assessment (PEL 2016a), which describes
the predicted underwater noise measurements, based on measurements undertaken as part of the
construction of the Naval Wharf at the Port (McCauley et al 2002). The piling methods for this
Project are considered similar to the work conducted at the Naval Wharf and therefore PEL
predicted underwater noise levels would be similar. These are shown in the below table.
Table 3-2 Impact Piling Underwater Noise Predictions (Source: PEL 2016a)
3.3.1 Underwater Noise Monitoring
Marine species’ responses to underwater noise include changes in vocalisation, resting, diving and
breathing patterns, changes in mother-infant spatial relationships and avoidance of the noise
source (PEL 2016a). The framework for management and mitigation of underwater noise impact
from piling activities includes observation zones, shut-down zones and soft-starts. These
procedures are outlined in the Project’s Aquatic Ecology CEMP Sub-plan (Revision 1, 9 August
2017).
Monitoring of underwater noise is not required for the Project. In the event that underwater noise
impacts from piling are shown to be impacting marine species, the Monitoring Improvement
Procedure outlined in the Project’s Aquatic Ecology CEMP Sub-plan (Revision 1, 9 August 2017) is
to be followed.
3.4 Above-water Noise Assessment
An assessment of the predicted above-water noise levels associated with piling activities, and the
noise monitoring that will be conducted is described in detail in the Construction Noise Monitoring
Program, which is detailed in Section 5 of this Noise and Vibration CEMP Sub-plan.
3.5 Above-water Vibration
A Construction Vibration Assessment conducted by PEL (2016a) predicted vibration levels of plant
at a range of distances. Table 3-3 presents a summary of these predicted levels, based on 200kNm
hammer operating at full capacity.
Noise and Vibration CEMP Sub-plan Advisian 19 of 42
Table 3-3 Predicted Vibration Levels (Source: PEL 2016a)
These results indicate that vibration levels at the nearest potentially impacted hillsides, adjacent to
wharf, could potentially reach 2-3mm/s during piling at refusal. However, typical vibration levels of
less than 1mm/s are expected, though vibration testing will confirm the predicted levels (refer to
Section 3.5.3).
3.5.1 Human Comfort
When vibration comprises repeated events, each of a similar value and duration, a Vibration Dose
Value (VDV) may be calculated. Acceptable values for impulsive vibration in the range of 1-80Hz
are provided in the Assessing Vibration a Technical Guideline (DECC 2006). These are shown in
Table 3-4, of which only the daytime values are of relevance to Stage 2 of the Project.
Table 3-4 Acceptable Vibration Dose Values for Intermittent Vibration (m/s1.75
) (Source: PEL
2016a, as derived from EPA 2006)
Predicted VDV’s were calculated by PEL (2016a) and compared with the Guidelines (EPA 2006), for
the nearest sensitive receiver (located 250m from the Project). The results are provided in Table 3-5
and will be confirmed following vibration testing (refer to Section 3.5.3).
Noise and Vibration CEMP Sub-plan Advisian 20 of 42
Table 3-5 Predicted Vibration Dose Levels (Source: PEL 2016a)
3.5.2 Building Damage
Given the absence of an Australian Standard, PEL (2016a) conducted a Vibration Assessment on
Building Damage based on the German Standard (DIN 4150-3-1999 Structural Vibration – Part 3
Effects of vibration on structures). The recommended limits from DIN4150 are shown above in Table
3-3 and compared to the predicted vibration levels of plant at a range of distances. The results of
these predictions show that vibration levels are not expected to cause any building damage. These
predictions will be confirmed following vibration testing (refer to Section 3.5.3).
3.5.3 Vibration Testing
Vibration testing was a recommendation of the PEL (2016a) report given predicted vibration levels
were highly conservative and could vary significantly with site-specific ground conditions.
Therefore, a Senior Acoustic Engineer from PEL will undertake vibration testing at the
commencement of piling to confirm the predicted vibration levels described.
Testing will include measurements at decreasing distances from the nearest sensitive receivers
toward the piling activities to estimate site-specific vibration propagation. Testing will occur over a
two-week period at the commencement of piling.
Testing will involve the following steps:
Measurements using a vibration monitor with triaxial accelerometer;
The accelerometer coupled to the ground/structures with consideration to AS2775 Mechanical
vibration and shock – Mechanical mounting of accelerometers;
Determination of vibration dose values and peak particle velocities in accordance with
Assessing Vibration: A Technical Guideline (DEC 2006); and
Reporting, including date, time and location of monitoring, the name of the person
conducting the monitoring, the peak particle velocity and vibration dose value.
Following completion of the testing a report summarising the findings compared to the relevant

4 Management Control Measures
An Environmental Risk Analysis was undertaken during the preparation of the EIS to identify
potential environmental impacts associated with the construction (and operation) of the Project.
The Environmental Risk Analysis also considered the proposed mitigation and management
measures for the Project and residual risks following their implementation. Noise and vibration was
one of the four key environmental risks identified in the Environmental Risk Analysis (Advisian
2016).
As part of the Project requirements (as described in Section 5 of the CEMP), an Environmental Risk
Assessment (ERA) has been developed in relation to Stage 2 construction activities to form part of
the Project Risk Assessment. The CEMP contains this ERA and identifies key environmental risks
applicable to Stage 2 construction activities and management controls to ensure that any risks are
managed to ALARP. The ERA identifies noise and vibration and associated risks as low-medium.
The Contractor will implement reasonable and practicable measures to avoid or minimise impacts
to the environment and community that may arise from the Project. The Contractor will ensure that
work is performed in a way that minimises impacts on the natural environment and complies with
the CEMP and related procedures, relevant legislation, regulations and rules, licences, approvals
and Project commitments made by the Principal.
In line with Condition E10 of the Infrastructure Approval, respite periods will be provided given
noise is expected to exceed the Highly Affected Noise level of 75dBLAeq, 15 minute during piling
activities. The timing of respite was discussed in consultation with the CCC, and the following
arrangements have been agreed during piling activities:
Planned respite from pile driving for a 1 hour duration during the period of 12:00pm and
2:00pm; and
Non-scheduled respite during natural breaks in construction activities, such as while resetting
for piles.
Specific control measures required to manage environmental impacts during the construction
works are described in the CEMP and must be complied with by all Contractor(s), as relevant to
their scope of work. Table 4-1 contains the relevant management controls from the CEMP relating
to noise and vibration for Stage 2 construction activities, as well as conditions of the other relevant
approvals, permits and licences for the Project.

5 Noise Construction Monitoring Program
This section forms the Noise Construction Monitoring Program required by Condition C10a and in
accordance with Condition C17 of the Infrastructure Approval.
The Monitoring Program has been prepared in consultation with BVSC and EPA. The details of the
consultation undertaken are set out in Section 2 with copies of written correspondence between
the Principal and the agencies provided in Appendix A.
5.1 Baseline Data
Baseline noise monitoring was conducted by acoustic specialists, Pacific Environment Limited (PEL)
between 10 December and 19 December 2015 (PEL 2016a). Monitoring was conducted at three
locations (Figure 5-1, Table 5-1); L1, L2 and L3. L1 was selected to be representative of the existing
traffic noise conditions as it is located just next to Albert Terrace; the only route that connects the
port with the rest of the town and inland. L2 and L3 are considered representative of the two Noise
Catchment Areas (NCA1 and NCA2).
Figure 5-1 Noise Catchment Areas and Noise Monitoring Locations (source: PEL 2016a).
Noise and Vibration CEMP Sub-plan Advisian 26 of 42
Table 5-1 Noise Monitoring Locations, MGA Zone 55 (source: PEL 2016a)
The existing acoustic environment was characterised by a combination of long term (unattended)
(refer to Table 5-2) and short term (attended) (refer to Table 5-3) noise measurements.
Table 5-2 Short term (attended) Noise Measurement Results (source: PEL 2016a)
Noise and Vibration CEMP Sub-plan Advisian 27 of 42
Table 5-3 Long term (unattended) Noise Monitoring Results (source: PEL 2016a)
Noise monitoring indicated a semi-rural environment, strongly influenced by intermittent noise
sources such as traffic and activities around the port (commercial and industrial) and that the
acoustic environment is slightly different depending on the Noise Catchment Area (PEL 2016a).
Full details of the baseline study are detailed in the Noise, Vibration and Air Quality Assessment
report prepared by PEL (PEL 2016a).
Further noise monitoring has been undertaken more recently during Stage 1 Construction
activities. It was concluded that the baseline noise environment was generally similar to the
monitoring results described in the PEL (2016a) Report.
No further baseline data is proposed to be collected in relation to noise for the Project.
5.2 Project Specific Noise Levels
Project-specific noise management levels were determined by PEL (2016a) using the baseline
results described in Section 5.1, a summary of which are provided in Table 5-4.
Table 5-4 Project Specific Construction Noise Management Levels, dB(A) (source: PEL 2016a)
5.3 Above-water Noise Assessment
A construction noise assessment was completed by Pacific Environment Limited (PEL) (2016a) for
the Project. Those relating to Stage 2 construction activities only will be discussed.
Noise and Vibration CEMP Sub-plan Advisian 28 of 42
Stage 2 construction activities were modelled via two scenarios; piling (shown below as Scenario 3)
and wharf extension construction works (shown below as Scenario 4), both during daytime hours.
The indicative construction fleet for the modelling is shown in Table 5-5. Predicted construction
noise from piling and wharf construction works were determined for each of the identified
sensitive receivers (PEL 2016a) (refer to Figure 5-2 and Figure 5-3). Full predicted noise levels for
the relevant construction scenarios are available in PEL 2016a, with a summary shown below in
Table 5-8 and Table 5-9, noting that for impact piling within Scenario 3, a +5dB impulsivity penalty
was applied as per the Interim Construction Noise Guideline (ICNG) (DECC 2009). Relevant noise
levels have been presented with a magnitude of noise exceedance (refer to Table 5-8), with red
indicating the predicted noise level that exceeds the “Highly Noise Affected” (>75dB(A) criteria).
The below predicted noise levels (refer to Table 5-8 and Table 5-9) form the compliance levels for
Stage 2 construction activities.
Table 5-5 Indicative Construction Fleet for Noise modelling (source: PEL 2016a)
Noise sources were assessed during a 15 minute period, assuming the worst case scenario (running
continuously) with the exception of those shown in Table 5-6.

5.4 Above Water Noise Monitoring
As a result of the predicted noise levels and level of predicted exceedances above the Project-
specific noise management levels during piling (Scenario 3 described in Section 5.3), above-water
noise monitoring will be undertaken during piling activities.
Details of the Construction Noise Monitoring Program can be found in Appendix B, and is
summarised below.
Continuous noise monitoring shall be undertaken at two of the same (or close to, pending
resident-approval of the location) monitoring locations as the baseline and Stage 1 monitoring
locations (Figure 5-4) to verify noise levels during piling compared with the predicted noise levels
shown in Section 5.3. Where predicted noise levels are not being achieved, it will serve as
notification for the Project to review the implemented mitigation measures, or to temporarily halt
works and provide further respite.
Noise and Vibration CEMP Sub-plan Advisian 34 of 42
Figure 5-4 Noise monitoring locations during piling works
Construction noise levels during piling will be monitored via a combination of attended (for the
first two weeks of piling) and unattended (throughout the duration of piling) noise measurements.
Sound level meters (Figure 5-5) will include 1/3 octave frequency data and/or audio capture to
allow acoustic engineers to filter extraneous data and target piling noise sources to assist in the
determination of piling noise contribution to the measured levels.
Noise and Vibration CEMP Sub-plan Advisian 35 of 42
Figure 5-5 Example noise loggers to be used for noise monitoring
Monitoring will include:
Operator attended 15 minute measurements both during and outside piling activities at
locations representative of the nearest monitoring locations and sensitive receivers for the first
two weeks of pile driving works.
Unattended background noise measurements in consideration to AS1055.1. Monitoring will be
continuous over the period of piling. The noise loggers with telemetry reporting will upload
and save data every 15 minutes, to allow for remote viewing through a password protected
website.
Prevailing meteorological conditions over the monitoring period from the nearest Bureau of
Meteorology (BoM) automatic weather station(s).
All monitoring loggers will be calibrated by a NATA testing laboratory with infield checks of
instrument calibration. Calibration certificates shall be provided for record retention purposes.
5.4.1 Attended Monitoring
For the first two weeks of pile driving works, operator attended 15 minute measurements will be
undertaken both during and outside piling activities (during the daytime) at locations
representative of the nearest monitoring locations and sensitive receivers. The date, time and
location of monitoring will be recorded, in addition to the name of the person conducting the
monitoring and details of site activity, environmental noise characteristics and weather being
noted.
Noise and Vibration CEMP Sub-plan Advisian 36 of 42
Statistical descriptors will be recorded for 15 minute intervals, including LAeq, LA10, and LA90 levels.
5.4.2 Un-attended Monitoring
Unattended continuous noise monitoring will occur throughout piling activities. With data logging
to be collected over 15 minute statistical intervals for LAmax, LA1, LA10, LAeq, and LA90 descriptors. Data
will be presented as daily noise logger graphs.
Remote data download will be available via mobile internet (statistical descriptors for the standard
monitoring intervals, eg LAeq, 15 minute) to facilitate review of unattended noise levels and compliance
limits, in addition to informing any noise related enquiries or complaints. This will enable Project
staff to verify noise levels within a shorter time period (within several hours of a complaint or
enquiry).
5.5 Reporting of Monitoring Results
A high-level summary of noise (and vibration) monitoring results will form part of the Contractor(s)
weekly report described in Section 7.2 of the CEMP, detailing any noise and vibration related
incidents and details of any noise and vibration management reviews.
Formal monthly noise monitoring reports will be prepared, including:
Monitoring methodology;
Monitoring results and observations;
Instrument set calibration certificates;
Graphical presentation of all unattended noise logging data; and
A summary of any recommended or additional noise mitigation measures implemented and
an evaluation of their effectiveness.
Further detail relating to noise monitoring and vibration measurements will be included in the
Contractor(s) Environmental Management Monthly Report to the Principal described in Section 7.4
of the CEMP.
5.6 Monitoring Improvement Procedure
Where predicted noise levels are not being achieved, it will serve as notification for the Project to
review the implemented mitigation measures and work practices, or to temporarily halt works and
provide further respite.
Reviews of the Noise Construction Monitoring Program will be undertaken as relevant, where
deficiencies, non-conformances or issues are identified as a result of Contractor(s) and Principal
environmental inspections and audits, or community complaints. Following the identification of an
alternative management measure(s) that are considered to improve noise and vibration impacts,
relevant procedures and plans will be updated, and submitted to the ER for consideration and
approval under Infrastructure Approval Condition A16(j).

1. Acknowledgement to Country, welcome and apologies
Simon thanked attendees for coming to the meeting and acknowledged the traditional custodians and peoples of the Country, both land and sea, and paid his respects to Elders past and present. Simon also acknowledged meeting apologies.
2. Stage 2 overview
Mike provided an overview of Stage 2 works which included a discussion of the works to be undertaken as follows:
Dolphins – 30 piles
Wharf – 78 piles with approximately 23 rock sockets to be bored
Onshore bollards -15 piles with approximately15 rock sockets to be bored
Navigation Tower – 1 to 3 piles
Services installation
Line marking activities
Approved construction hours o Monday to Friday 7am to 6pm o Saturday 8am to 1pm o Sunday and Public Holidays – No Work o Additional rostered days off during the year.
Richard asked about the tug working and turbidity in the Port. Mike advised there were high spots on the seabed and that these high spots were being removed which has caused minor turbidity levels. Richard asked if the turbidity would be an issue for the Mussel Farm. Greg advised that the modelling that has been undertaken has shown that settling of the sediment would be relatively quick. It was discussed that a toxic algal bloom forced the temporary closure of the Mussel Farm prior to dredging commencing and the temporary closure is not related to dredging or any direction given to the mussel farm by the Department. The Mussel Farm has chosen to undertake maintenance on their vessels and harvest/grow out mussels from the Boydtown mussel farm during the dredging campaign. . Leanne suggested that additional communications should be prepared to communicate this to the community. John asked about the scour protection being laid and how to know if the mattresses were being laid in the right place. Mike advised there was a grid pattern being followed and that laying the mattresses was similar to paving. In addition, detailed hydrographic surveys were also being undertaken to ensure correct alignment, and that divers were under the water to guide the

mattresses into place. Rob advised the hydrographic survey is being done weekly and that Waterways were approximately a quarter of the way through the works.
3. Review of Stage 2 Construction Environmental Management Plan sub-plans
Mike advised the group that under the project’s Infrastructure Approval the Traffic, Access and Transport and Noise and Vibration sub-plans must be prepared in consultation with the CCC, the Bega Valley Shire Council and the Environment Protection Agency (EPA). These sub-plans will be sent to Environmental Representative for endorsement prior to being submitted to the Secretary of the Department of Planning and Environment (DP&E) for approval. It is envisaged that these sub-plans will not be approved until late February.
4. Traffic, Access and Transport sub-plan Rob Davis introduced himself as the Project Manager and Tomas Rooney as Lead Engineer for Waterway Constructions. Rob provided an overview of the sub-plan as follows:
Plan purpose/overview
Truck routes - proposed routes for 19m semi-trailers and articulated vehicles, 12.5m heavy rigid vehicles and 18.7m truck and dog, and for medium rigid vehicles and small rigid vehicles
Hours, duration and truck movements per day
Marine construction and vessel mooring zones
Minimising disruption to Port businesses
Pedestrian access arrangements
Managing public safety.
Transport routes Rob discussed the proposed routes using Calle Calle, Chandos, Museum, Barclay and Mitchell streets. Richard asked if there would be enough visibility at the intersection of Imlay and Wirriga Streets as this is quite dangerous. Rob advised he will review these routes and this intersection with his team. Greg confirmed with the group that traffic and transport assessment has been undertake to confirm safe access. Hours and truck movements per day Rob advised there will be up to 20 movements per day on some days such as concrete pours taking place but this would not happen every day. John asked who the concrete suppliers will be for the project. Rob advised that Waterway Constructions is currently negotiating this. It was also noted that truck drivers will undergo the site specific induction which included truck routes.
Management measures The following management measures were discussed:
Providing delivery instructions and access routes to suppliers along with purchase orders or provided separately prior to dispatch of materials for delivery
Providing regular suppliers (i.e. concrete trucks) with a site specific truck induction
Ensuring delivery vehicles do not park on public roads, and instead park within the Project site boundary
Developing a Vessel Interaction Management Plan to manage barge movements to and from the Port/Construction Site
Preparing anchor layouts for the main barge spreads and provide to Port Stakeholders as part of ongoing consultation
Ensuring regular consultation with the Port of Eden Harbour Master during construction to ensure maintenance of safe navigation for shipping.
Page 3 of 5
Site deliveries and access to Shelly Beach was discussed as well as managing safety by keeping pedestrians separate from vehicles. The marine works area/zone was discussed with marker buoys on anchors. These drawings will be updated regularly and provided to the Harbour Master.
Richard asked about the pedestrian crossings at the Port and that he had witnessed pedestrians nearly being hit by vehicles. Greg advised he would follow up on ownership of the different crossings at the Port and would advise them of the near misses.
5. Noise and Vibration sub-plan
Tony and Rob provided an overview of the sub-plan as follows:
Plan purpose/overview
Overall duration of piling
Construction hours
Background noise and predicted noise levels per activity
Noise monitoring locations and testing
Vibration testing
Mitigation measures including respite periods
Community consultation and contact details. Piling activities summary Rob discussed the proposed duration of piling:
Mid April 2018 – End October 2018 (approx. 6 to 7 Months)
Main Wharf Piles (end April – end Sept – incl. sockets)
Land-based Bollard Piles (mid April – end July incl. sockets)
Dolphin Piles (end July – end Oct)
Background noise and predicted noise levels per activity
Mitigation measures including respite periods.
Noise monitoring Construction noise levels during piling will be monitored via a combination of attended (for the first two weeks of piling) and unattended (throughout the duration of piling) noise measurements. Monitoring will include:
Operator attended 15 minute measurements both during and outside piling activities at locations representative of the nearest monitoring locations and sensitive receivers for the first two weeks of pile driving works. The date, time and location of monitoring will be recorded, in addition to the name of the person conducting the monitoring and details of site activity, environmental noise characteristics and weather being noted.
Unattended background noise measurements in consideration to AS1055.1. Monitoring will be continuous over the period of piling. The noise loggers with telemetry reporting will upload and save data every 15 minutes, to allow for remote viewing through a password protected website.
Rob showed the CCC images of the Casilis barge and how piling will be done on the barge, the Calliope barge which is due to arrive closer to piling commencement, and the Kochi barge.
Leanne asked how many piles will be going into hard rock. Rob advised that it is expected that they will be hitting hard rock for the on-shore bollards and some of the piles on the wharf. However, a smaller hammer will be used for some of these piles reducing noise impacts. Tony noted that when piles hit hard rock, drilling is then undertaken. Respite periods Rob discussed respite periods as follows:
Planned respite from pile driving for a 1 hour duration between 12pm and 2pm
Page 4 of 5
Non-scheduled respite during natural breaks in construction activities, such as while resetting for piles
Moving barge/rig position
Setting up the gate
Rigging the pile for lifting
Lifting the pile into the gate
Disconnecting the pile (rigging gear)
Lifting the hammer onto the pile
Driving the pile (20 min to 90 min)
Two crib breaks per day. Mike advised that there are 135 piles to be driven and that some days only one pile may be driven. Tony advised there will be days when only set up will take place and there may be days when more than one pile will be driven. Gail noted that some businesses at the Port are not open after 3pm. Leanne asked the possibility of modifying the program and being flexible to business owners. Rob advised that Waterway Constructions will accommodate businesses as much as possible whilst still adhering to the program. John asked how loud the piling will be. The meeting discussed the piling previously undertaken at the Navy Wharf, and noise type and loudness. Vibration and testing Rob discussed the following:
Current predicted vibration modelling (based on the modelling previously done by Pacific Environment Limited (PEL) shows that vibration levels should be well below the guidelines
A Senior Acoustic Engineer from PEL will undertake vibration testing at the commencement of piling over a two week period to confirm predicted vibration levels
Testing will include measurements at decreasing distances from the nearest sensitive receivers toward the piling activities to estimate site-specific vibration levels.
Testing will involve the following steps:
Taking measurements using a vibration monitor with a triaxial accelerometer which will be coupled to the ground and/or structures
Determining the vibration dose values and peak particle velocities in accordance with Assessing Vibration: A Technical Guideline (DEC 2006)
Reporting, including date, time and location of monitoring, the name of the person conducting the monitoring, the peak particle velocity and vibration dose value.
Following completion of testing, a report, summarising the findings compared to the relevant guideline vibration levels, will be completed. Mike discussed utilising PEL through the EIS period and dredging. Rob noted that if there are higher than predicted levels of vibration other mitigation measures may be investigated and implemented after the testing period. Leanne asked if the same consultation will be in place as there was for the dredging. Coral advised this will be the case. Management measures The following management measures were discussed:
Implementation of respite periods (planned and unplanned)
Where possible, plant and equipment will be selected that can be fitted with options to minimise noise such as covers, mufflers, shrouds, etc
Page 5 of 5
Plant and equipment will be turned off and not left idling when not in use
Plant and equipment will be well maintained and serviced regularly to ensure it is not generating excessive noise
Use of high pressure washes to green cut concrete instead of using pneumatic scabblers
A concreting work method statement will be developed with consideration for minimising noise, such as care to be taken not to contact the pile with the concrete pokers during the concrete works
Site induction protocols will include awareness of noise generating activities and mitigation measures that are to be implemented
Piling work method statement shall be developed and implemented during piling works
Soft-start procedures for piling operations will be developed and implemented during piling works
Noise monitoring will be undertaken during piling activities
The community will be notified by the department in the lead up to noise intensive activities commencing such as piling
Works will be scheduled wherever possible to minimise the number of noisy plant and equipment operating at any one time.
Mike noted that by having a soft start procedure for piling the noise levels will gradually increase as the pilling increases from half blows to full blows.
6. Questions Glenn noted that larger piles to be delivered by water and stored at the laydown area at the Navy Wharf with only some of the smaller piles to be delivered by road. Leanne asked if mid-April is a definite commencement date for piling. Rob advised that this date is highly likely. Glenn noted that delivery of the piles is the critical path for the project. Simon noted that DP&E approval of plans will be occurring concurrently and that DP&E has been notified that these plans will be submitted shortly for their review. John asked if scour protection was running to schedule. Mike advised that scour protection works are on schedule to be completed in late January - early February and there will be a slight lull in works before Stage 2 commences. Glenn advised the sweeper dredge will come back at the end of the project to flatten out any lumps on the seedbed caused by the piling barge anchoring. Gail asked if work activities will have to be reduced with the arrival of cruise ships in the next week. The meeting discussed the exclusion zone in place around the divers and the works. Glenn noted that a large number of deliveries to site had been made to minimise the number of vehicles at the Port on a cruise day.
7. Next steps
Simon advised attendees that they will be sent the draft minutes and presentation for review and if they have any queries to direct these to Coral. Simon reiterated that the sub-plans once endorsed by the ER will then be submitted to the Secretary of DP&E for approval.
8. Next Community Consultative Committee meeting
Simon advised that the next CCC meeting will be held on 31 January 2018 and thanked the CCC for attending. Gail asked about the project shutting down over the Christmas period and was advised this will be from 22 December to 8 January. The meeting closed at 7.05pm.

1 Eden Breakwater Wharf Extension – Construction Piling Noise and Vibration Monitoring Program
Waterways plans to conduct piling including vibratory and impact piling during standard construction
hours over an estimated 40 week period, with an anticipated start of Q2 2018.
The Infrastructure Approval requires a Noise Monitoring Program for the piling works. The Construction
Environmental Management Plan (CEMP) for the works requires vibration testing to confirm levels at
sensitive receivers as a result of the piling activities.
This program has been prepared with consideration to the requirements of the Infrastructure Approval
and CEMP. This program will be used to confirm vibration levels and monitor noise at surrounding
sensitive receivers and structures in Eden, and assist Waterways in the management of noise and
vibration impacts.
2 Scope of Work
Our proposed Scope of Work for the Project is outlined in the following sections.
Project Inception
Project kick-off meeting (teleconference)
Preparation of monitoring safety documentation
Preparation of monitoring equipment
Baseline Noise Environment
The background noise environment will be confirmed based on the monitoring completed for the Port of
Eden Redevelopment Noise, Vibration and Air Quality Assessment (Pacific Environment 2016) and the
more recent monitoring program (September to November 2017) undertaken for the Stage 1 works
(Pacific Environment 2017). A brief report will be provided, and will include review of:
Operator attended 15 minute measurements during the proposed day time construction hours, at
locations representative of the monitoring locations and sensitive receivers.
Previous unattended background noise measurements (Pacific Environment 2016, 2017).
Intensive Piling Noise and Vibration Monitoring
Prior to commencement of piling activities a Senior Acoustic Engineer will be deployed to Eden, full
time, to assess noise and vibration from piling activities. It is anticipated that intensive monitoring will be
completed within a 2 week period from the commencement of piling.

The objectives of the intensive monitoring will be as follows:
Identify potential noise and vibration impacts from piling activities.
Confirm piling vibration levels and level of impact at sensitive receivers
Simultaneous confirmation of piling noise emissions and level of impact at sensitive receivers.
Investigate any noise and vibration related complaints
Provide noise and vibration mitigation and management recommendations as required.
Prepare an assessment report of noise and vibration impacts for the first 2 weeks of piling.
Vibration Testing (2 week intensive)
It is understood that up to 100 piles will be driven along the length of the breakwater wharf, and 16 larger
piles for the dolphin structures. A Senior Acoustic Engineer will undertake vibration testing to confirm
vibration impacts from piling activities. This would include vibration testing at increasing distance from
the piling activities towards sensitive receivers (buildings and structures), in order to estimate site
specific vibration propagation and estimate site specific safe working distances.
Data will be collected during the first two weeks of piling, and will include:
Vibration testing to be conducted at increasing distanced from the piling activities towards
sensitive receivers and structures.
Vibration dose values and peak particle velocities will be determined in accordance with Assessing
Vibration: A Technical Guideline (DEC, 2006), and safe working distances established for the
activities.
Measurements will be completed using a vibration monitor with a triaxial accelerometer.
The accelerometer would be established with consideration to AS 2775. Mechanical vibration and
shock - Mechanical mounting of accelerometers.
Noise Monitoring
Noise Monitoring (2 weeks intensive) Pacific Environment will install telemetry noise loggers at two representative receiver locations for the
ongoing monitoring of the ambient noise environment and piling activities. These locations are
representative of noise affected receivers in surrounding catchment areas and are presented in Figure
1. The loggers will remain on site for the duration of piling activities, and data will be used in conjunction
with baseline noise information conducted for previous stages of the project, including the dredging
background noise investigations. This data would be supplemented by attended noise monitoring during
this period to validate predicted impacts from piling activities for the intensive two week period.
Data will be collected for the duration of piling, and will include:
Operator attended 15 minute measurements during daytime periods at locations representative
of the nearest monitoring locations and sensitive receivers during the initial 2 week monitoring
period.

Continuous unattended noise logging at two locations representative of the nearest monitoring
locations, consistent with the receivers identified in the Port of Eden Breakwater Wharf Noise and
Vibration Assessment (Pacific Environment 2016) and the Night Dredging Protocol (Pacific
Environment 2017).
Noise monitoring would be undertaken with consideration to the method detailed in Australian
Standard (AS) 1055.1:1997 Description and Measurement of Environmental Noise.
Unattended and attended measurements will be performed using Class 1 sound level meters,
such as Acoustic Research Labs NGARA and NTI Audio XL2 hand held meters. These
instruments are able to provide 1/1 and 1/3 octave spectral analysis on statistical descriptors which
to assist with the removal of extraneous noise sources.
o The unattended noise loggers with telemetry reporting upload noise data every 15
minutes. The data is saved and available for viewing over password protected website.
Meteorological conditions over the monitoring period will be collected from the nearest Bureau of
Meteorology automatic weather station.
The intensive period is anticipated to be of 2 weeks duration, and it is envisioned that the bulk of the
attended monitoring to confirm the extent of noise impacts can be completed within this period of
monitoring. Following this period data collection and reporting will occur remotely.

3 Methodology
The determination of noise compliance and vibration impact involves monitoring and measurement to
determine the contribution of the piling noise sources excluding extraneous noise sources such as;
traffic, fauna (birds and insects) and other industrial noise sources, and determination of site specific
values of vibration over distance.
Baseline noise monitoring investigations completed to date as part of the Port of Eden Breakwater Wharf
environmental management reporting, including baseline investigations for the previous dredging works,
will be used to supplement current measurement data.
Vibration Testing
Intensive Vibration Monitoring The vibration testing methodology will involve the following steps:
Vibration testing to be conducted over a two week period at decreasing distances from sensitive
receivers and structures towards the piling activity (approximately 10 m to 250 m, dependent on
location suitability).
Measurements will be completed using a vibration monitor with triaxial accelerometer.
Accelerometer will be coupled to the ground/structures with consideration to AS 2775. Mechanical
vibration and shock - Mechanical mounting of accelerometers.
Vibration dose values and peak particle velocities will be determined with consideration to
Assessing Vibration: A Technical Guideline (DEC, 2006).
In the event of identification of vibration impacts above anticipated levels, a recommendation will
be made to reduce vibration levels via modification to the piling method.
Reporting will involve date, time and location of monitoring, name of person conducting the
monitoring, PPV and VDV.
Reporting A summary report will be prepared to fulfil the requirements of the CEMP for the intensive vibration
testing. The reporting will include:
Details of vibration testing methodology.
Testing results and observations.
Instrument set calibration certificates.
A summary of measured vibration levels with consideration to predicted levels.

Remote data download via mobile internet (statistical descriptors for the standard monitoring intervals
eg LAeq, 15minute and LA1 1 minute) implemented to facilitate ongoing compliance assessment and review of
unattended noise levels in the event of a complaint. This can be used to remotely verify noise levels
within a shorter time period (within several hours of a complaint event).
Piling activities are anticipated to be readily identifiable through statistical analysis and observation of
trends. This will reduce the ongoing operational component of the monitoring, as data can be sourced
remotely and processing can be completed without ongoing presence of acoustic consultant.
Monthly reports will be prepared to fulfil the requirements of the CEMP. The reporting will include:
Details of monitoring methodology.
Monitoring results and observations.
Instrument set calibration certificates.
Summaries of measured noise levels, including graphical presentation of all unattended noise
logging data, a summary of any complaints received, including their nature and time.
A summary of any additional noise mitigation measures implemented, and an evaluation of the
effectiveness of any response measures implemented.
The review and analysis of unattended monitoring data will include download, reporting and analysis of
measured noise levels and trends on a monthly basis with daily monitoring graphs presented and
analysed.
