1 PURPOSE

This Consolidated Out of Hours Construction Noise and Vibration Management Plan (COHNVMP) has been produced to supplement Armadale Access Alliance’s (AAA) Environmental Management Plan (EMP) and the Construction Noise and Vibration Management Plan (CNVMP) for implementation by the Alliance throughout the Armadale Road to North Lake Road Bridge (ARNLR) Project.

The COHNVMP outlines AAA’s approach to the management of nuisance noise and vibration created from the Project. This Plan is an extension of the CNVMP and provides a detailed assessment of noise and vibration for works that are to be conducted outside of normal construction hours (i.e. between 1900 hours and 0700 hours). The COHNVMP has been developed with reference to the documents outlined in Section 2 below.

This is an overarching plan, applicable to a limited number of tasks which are expected to be regularly undertaken out-of-hours throughout the duration of the Project. The scope of works and associated tasks are outlined in Section 4 of this Plan. For works that are not covered within this Plan, or where significant changes are required, the normal Out-of-Hours Works (OOHW) approval process as described in the CNVMP must be followed. This includes a detailed assessment of noise levels, mapping of impacts, identification of sensitive receivers and submissions of approval request to Main Roads Western Australia (MRWA) and the Local Government Authority (LGA), the City of Cockburn.

This plan does not include the dates of any works to be undertaken. An ‘Out of Hours Works Notification Form’ shall be submitted to MRWA and the LGA which will set out the dates of works and the activities to be undertaken. A copy of the ‘Out of Hours Works Notification Form’ is provided in Appendix A.

This COHNVMP aims to satisfy the following objectives:

• Provide calculations for the assigned noise levels received by properties along the alignment • Identify expected noise (including sound penalties where required) generated by works using

sound power levels from plant and equipment • Where sound levels to be received by closest sensitive receivers exceed assigned levels, identify

and implement methods to decrease sound levels where possible • Minimise and manage noise generation from the project area during out of hours working • Mitigate potential impacts on the environmental values, and the health, amenity and welfare of

the community resulting from the OOHW • Ensure that noise generated from the construction works complies with the relevant statutory

requirements • Ensure that all reasonable and practical measures are undertaken during the works to minimise

noise and vibration emissions from site • Ensure that all works and activities within the scope are undertaken in a manner that will

minimise the noise and vibration impacts on sensitive receivers

3 ASSIGNED NOISE LEVELS

Assigned noise levels are the levels of noise allowed to be received at a premises at a particular time of the day. There are different assigned levels for noise sensitive, commercial and industrial premises. The assigned levels also depend on how close the noise sensitive premises are to industrial and commercial areas, and major and minor roads. These assigned noise levels always apply at the premises receiving the noise.

The assigned levels have been adopted on the Project as a noise target for construction works undertaken outside normal operating hours. The table of assigned levels, shown in Table 1 identifies three types of assigned levels: LAmax, LA1 and LA10.

3.1 Influencing Factors

As per Schedule 3 of the Environmental Protection (Noise) Regulations 1997, the assigned noise level that a sensitive receiver may be subject to can be modified by the surrounding land uses for the property. The influencing factor (IF) increases with the number of commercial and industrial premises in the vicinity of the receiver as well as the presence of major or minor roads. This is calculated by considering land use zoning and the volume of traffic that utilises the road infrastructure within 100m and 450m of the receiver.

3.1.1 Influencing Factors – Land Zoning

Influencing factors based on the surrounding land use within a set distance from the sensitive receiver are developed from local government zoning maps. Industrial and commercial land uses are likely to generate an increase in the volume of sound within a set area, and therefore any sensitive premises located within finite proximity to these areas are taken as being be more tolerant of higher volumes of sound. To calculate the influencing factor two concentric circles representing 100m and 450m radii are placed from the noise sensitive premises, any land within the circles that is classified as Type 1 land (industrial and utility) or Type 2 land (commercial) is calculated as a percentage of the full area of each circle. The percentage is then used to calculate the influencing factor to the nearest decibel.

3.1.2 Influencing Factors – Transport Factors

Sensitive premises that are located within a defined distance from a Primary Road (a road that takes in excess of 15000 vehicles per week day) or secondary road (a road that takes more than 6000 but less than 15000 vehicles per week day) are deemed to be influenced by transport. The transport factor can be a maximum of 6dB added to the influencing factor. The values to be added as transport factors are summarised in Table 2.

Traffic data presented in Table 3 is based on the average number of vehicles recorded Monday to Friday between 2013 and 2019. This traffic count data was obtained from Main Roads Trafficmap website (https://trafficmap.mainroads.wa.gov.au/map).

3.1.3 Influencing Factor Calculation

Due to the limited area of the works impacted by industrial/commercial land zoning factors, AAA have opted not to utilise the influencing factor generated from land uses. Nearby industrial and commercial premises are also not expected to operate outside of normal construction hours. Transport Factors only shall be used to determine assigned noise levels for sensitive premises.


3.2 Site Specific Assigned Noise Levels

The assigned levels are statistical noise levels over a Representative Assessment Period (RAP); for this project the RAP 15 minutes has been chosen as an appropriate period for assessing noise from the project. The DWER Noise Regulations specify 15 minutes as the minimum assessment time and it is also the DWER’s preferred RAP for night time operations. As the sites will be operational for over 10% of the RAP, the LA10 statistical noise criteria is the relevant criteria for this project. The specific LA10 assigned levels for the predicted worst affected receivers (within 100m of the Project boundary) are outlined in Table 4. These assigned levels have been calculated by the addition of a Transport Factor. For simplicity, roads within 100m of the Project boundary have been identified and the periods have been split into day (0700 – 1900 Monday to Saturday and 0900 – 1900 Sundays and Public Holidays) evening (1900 – 2200 all days) and night (2200 – 0700 Monday to Saturday and 2200 - 0900 Sundays and Public Holidays).

Where a given task or set of works is calculated to exceed or significantly contribute to an exceedance of the assigned sound level for affected sensitive properties, AAA shall notify properties within 100m of the Project boundary relevant to the work area. A noise emission is generally understood to ‘significantly contribute’ to an exceedance if it is higher than a level which is 5.0 dBA below the assigned level at the point of reception.

4 SCOPE OF WORKS

The ARNLR Project involves the construction of a bridge over the Kwinana Freeway connecting Armadale Road to North Lake Road and construction of free-flowing traffic lanes on Armadale Road through the Solomon Road and Tapper Road intersections. Full connectivity will be retained at the intersections of Solomon Road and Tapper Road through grade separated roundabouts.

This plan aims to identify all standard tasks required to occur out of hours and their corresponding noise levels. This will allow for a streamlined and standardised approach to the assessment of OOHW activities and the approvals process.

The standard tasks expected to be repeated throughout the duration of the ARNLR Project are detailed in Table 5 below.

Table 5 – List of standard tasks to be undertaken during the Project

Task

5 NOISE AND SENSITIVE RECIEVERS

5.1 Plant and Noise Generation

Construction activities often require multiple items of plant operating at the same time. The accumulation of sound power levels from multiple items of plant will result in a higher sound level than if one item was operating alone.

The plant described in Table 6 have been grouped according to the standard tasks required for the scope of works. In order to simplify calculations, assessments for all tasks have been calculated based on all plant operating simultaneously at the same location to provide a maximum sound level. However, this assumption will likely result in an overestimation of actual accumulative sound levels.

The calculation for the addition of various noise sources to be utilised is LTOT=10Log(10L1/10+10L2/ 10+10L3/10+………10Ln/10) where L1, L2, L3, Ln are individual noise sources.

The calculated sound levels generated from each task are provided in Table 7.

Where multiple tasks are completed in an area simultaneously, the total sound levels per task shall be used to calculate the total sound levels for the area. Where penalties are applied to multiple tasks, they shall not be duplicated. Therefore, the total penalty cannot exceed 15dB as stated in Section 5.2 below.


5.2 Intrusive Characteristics and Associated Penalties

Intrusive or dominant noise characteristics namely; modulation, impulsiveness and tonality have the potential to impact on a receiver’s perception of sound. If noise emitted from any premises when received at any other premises cannot reasonably be free of intrusive characteristics, then a series of adjustments must be added to the emitted levels (measured or calculated) and the adjusted level must then be compared to the assigned level. These adjustments are detailed in Table 8.

Table 8 - Table of Adjustments

Adjustment where noise emission is not music. These adjustments are cumulative to a maximum of 15 dB.

Where tonality is present Where modulation is present Where impulsiveness is present

+5dB +5dB +10dB

A total penalty of up to 15dB can be applied to any given sound with all or one of these characteristics.

Where a task is expected to generate noise with any of the characteristics listed above, the relevant penalties will be applied to the overall sound level for the given task. The addition of the applicable penalties is identified in Table 9. Table 9 also provides a total sound calculation and the dissipation distances to achieve the various assigned noise levels (relevant to the appropriate Transport Factor).

5.3 Sensitive Receivers

Sound levels expected to be received at residential properties from construction activities shall be calculated using the formula LpA= LWA-20log10 x R - 8 (where R = distance in metres) in accordance with AS 2436-2010 (point source in a free field calculation). Dissipation of sound shall be calculated at a loss of 6dB for every doubling of distance. The total distance for sound to dissipate to the assigned sound levels for residential properties shall be used to identify all properties potentially impacted by the works.


Table 9 – Calculated sound levels vs distance for sound to dissipate to assigned levels with and without penalties. The distance to dissipate is based on assigned levels with varying Transport Factors including no Transport Factor applied, +2dB (for minor roads) is applied and +6dB (for primary roads) is applied.

6 VIBRATION AND SENSITIVE RECEIVERS

AAA identifies that any vibration above 1 mm/s-1 peak particle velocity (PPV) received at a sensitive receiver has the potential to cause disturbance to the occupier during OOHW.

Tasks that have potential to generate vibration above 1mm/s-1 include the following:

• Task 2 – Base Course Installation • Task 7 – Demolition • Task 8 – Drainage Installation and Backfilling • Task 10 – Embankment Construction • Task 13 – Foundation Preparation • Task 24 – Seal and Asphalt Replacement • Task 27 – Subbase Installation • Task 28 – Subgrade Preparation • Task 30 – Trenching Works for Service Installation

AAA shall manage works to minimise the impact of vibration on residential properties between non-standard construction hours by conducting vibration assessments of works, modelling the potential vibration, and monitoring.

Plant and equipment that is most likely to generate vibration includes plate compactors, tracked plant, smooth drum rollers and pad-foot rollers. The rollers are expected to generate vibration that dissipates furthest from its source, and therefore shall be used to model expected vibration from works.

Vibration data from previous onsite measurements have been used to calculate the distance required for vibration to dissipate to below 1mm/s. The dissipation curves for the smooth drum roller and the pad foot roller are provided in Appendix F.

The distance required for the vibration to dissipate to beneath 1mm/s are provided in Table 10 for the various settings on the padfoot roller and the smooth drum roller.

7 APPROVALS PROCESS

The approvals process described below applies to tasks included within this Plan only. If other significant works are planned to occur out of hours, a separate, more detailed plan will be prepared and submitted to MRWA and the City of Cockburn for approval.

The approvals process is summarised in Appendix E.

STEP 1

•Engineer responsible for works to be undertaken will complete an Out of Hours Request form (Appendix C) and submit the completed form together with the required mapping files to the AAA Environmental Coordinator a minimum of 12 working days prior to works commencing.

STEP 2

•The AAA Environmental Coordinator will review the information provided to develop sound dissipation mapping and complete an Out of Hours Notification of Works form (Appendix A).

•The completed form will then be provided to the AAA Community & Stakeholder Engagement Team (CSET) 10 working days prior to works.

STEP 3

•AAA CSET will develop a notification letter (example provided in Appendix D) for distribution to the impacted sensitive receivers (if required).

• The Out of Hours Notification form and the notification letter will then be submitted to the City of Cockburn (Coc).

STEP 4

•The CoC will be asked to review the Out of Hours works application and provide any feedback before issuing approval at least 3 days prior to the proposed OOHW.

•Upon receipt of CoC approval, the notification letter will be distributed no later than 48 hours prior to the commencement of works.

•If CoC objects to the works being undertaken, AAA shall amend the plan (via addemdum) to address CoC concerns and re-submit the Out of Hours Notification form. Should this occur, the described process and timeframe for approval is reset unless otherwise agreed with CoC.


8 CONTROLS AND MITIGATIONS MEASURES

The construction works will be carried out in accordance with control of environmental noises practices set out in AS2436-2010 Guide to Noise Control on Construction, Maintenance and Demolition Sites. Controls to be implemented have been divided into three categories; management controls, source controls and path controls. All relevant controls are detailed in the following sections.

8.1 Management Controls

The noise mitigation management measures outlined in Table 11 will be implemented in order to reduce disturbance to nearby receivers during the project.

Table 11 - Management Controls

Action Required Applies Details

Working hours Noise

Vibration

Construction activities are to be only undertaken between 7.00 am and 7.00 pm Monday to Saturday unless otherwise approved. Information regarding working hours is to be included in Project Induction and Pre Start Briefings, Toolbox Talks etc.

Out of hours works Noise

Vibration

All requests for Out of Hours Works are to be assessed by the Environmental Coordinator using processes outlined in the CNVMP and COHNVMP.

Respite periods Noise

Vibration

Restricting time when noisy and vibration intensive works are carried out. Works will be scheduled in order to reduce the impact of noise and vibration on sensitive receivers where practicable.

Implement community consultation measures

Noise

Vibration

• Periodic notification (monthly letterbox drop or equivalent)

• Website • Project info line • Email distribution list • Community Based Forums

Site inductions Noise

Vibration

All AAA employees, contractors and subcontractors are to receive an environmental induction. The induction must at least include:

• All relevant project specific and standard noise and vibration mitigation measures

• Relevant licence and approval conditions • Permissible hours of work • Any limitations on high noise generating activities • Location of nearest sensitive receivers • Construction employee parking areas • Designated loading/ unloading areas and processes • Site opening/closing times (including deliveries) • Environmental incident response processes



Behavioural practices Noise No swearing or unnecessary shouting or loud stereos/radios on site.

No dropping of materials from height, throwing of metals items and slamming of doors.

Monitoring Noise A monitoring program as specified in Section 8.4 is to be carried out for the duration of the works

Cease work Noise

Vibration

In the event of exceedance of action targets, impacts can be controlled by ceasing the activity until received noise/vibration levels can be reduced to within acceptable levels.

8.2 Source Controls

The source noise mitigation measures outlined in Table 12 will be implemented in order to reduce the disturbance to nearby receivers during the project.

Table 12 - Source controls


Equipment selection Noise All fixed plant at the work sites are to be selected to be as quiet as practicable and where required, fitted with silencers, acoustical enclosures and other noise attenuation measures.

Equipment selection Vibration Quieter and less vibration emitting construction methods will be used where feasible and reasonable.

Rental plant and equipment

Noise The noise levels of plant and equipment items are to be considered in rental decisions.

Maintenance of plant Noise

Vibration

Vehicle, plant and equipment maintenance schedules and lubrication will be maintained as per manufacturers’ specifications.

Regular checks are to be undertaken to ensure all equipment and vehicles are in good working order and are operated correctly.

Use and siting of plant

Noise Simultaneous operation of noisy plant within discernible range of a sensitive receiver is to be avoided.

The offset distance between noisy plant and adjacent sensitive receivers is to be maximised.

Plant used intermittently to be throttled down or shut down when not in use.

Noise-emitting plant to be directed away from sensitive receivers.

Plant inspection Noise

Vibration

All plant and equipment is to be inspected for use on site to ensure it is compliant prior to use on site.

Plan worksites and activities to minimise noise and vibration

Noise

Vibration

Plan traffic flow, parking and loading / unloading areas to minimise reversing movements within the site.

Prevent vehicles and plant queuing to access site.



Non-tonal reversing alarms

Noise Non-tonal reversing beepers (or an equivalent mechanism) will be fitted and used on all construction vehicles and mobile plant used on site.

Minimise disturbance arising from delivery of goods to construction sites

Noise Loading and unloading of materials/deliveries is to occur as far as possible from sensitive receivers.

Site access points and roads as far as possible away from sensitive receivers will be used.

Dedicated loading/unloading areas to be shielded if close to sensitive receivers.

Delivery vehicles to be fitted with straps rather than chains for unloading, wherever possible.

Hand tools Noise As much as practical the use of hand tools such as grinders, impact wrenches, hammers etc. will be used in specifically designated areas as far as possible from sensitive receivers and preferably separated by a barrier. Metal on metal contact will be avoided where possible.

8.3 Path Controls

The noise mitigation path control outlined in Table 13 will be implemented in order to reduce the disturbance to the nearby receivers during the project.

Table 13 - Path controls


Shield stationary noise sources such as pumps, compressors, fans etc.

Noise Stationary noise sources will be enclosed or shielded whilst ensuring that the occupational health and safety of workers is maintained.

Shield sensitive receivers from noisy activities

Noise Use structures to shield residential receivers from noise such as site shed placement; fencing; erection of operational stage noise barriers (where practicable) and consideration of site topography when situating plant.

Should a permanent acoustic barrier for operational noise control be erected consideration will be given to building it prior to the rest of the construction works (i.e. noise walls).

Acoustic barriers Noise Erecting barriers on site at source where practical will be considered to reduce the impact of noise at receivers. AS2436 identifies the options for barriers to reduce noise emissions from construction sites.

8.4 Monitoring

8.4.1 Noise Monitoring

Monitoring will be undertaken to assess the noise generated by AAA construction activities and will be carried out in accordance to the Environmental Protection (Noise) Regulations 1997. A number of monitoring


stations will be established along the alignment in proximity to sensitive receptors. The AAA Team proposes to maintain up to seven (7) Casella C633C noise monitors. The locations of these monitors will likely be influenced by the location of works, particularly those undertaken out of hours.

Noise monitors shall be set up to send alerts if the calculated maximum sound level (Table 9) is breached. Should an alert be received, the supervisor of the works shall be informed for suitable action to be taken. All data collected by the noise monitoring units will be reviewed regularly by a suitably qualified person to ensure the Project is not contributing to excessive / unnecessary levels of noise.

8.4.2 Vibration Monitoring

Vibration monitoring using Instantel’s MicroMate sensors shall be conducted continually during out of hours’ construction activities. Vibration monitoring will likely occur alongside noise monitoring. The location of these monitoring stations will be dependent upon the location of out of hours works and corresponding sensitive receivers. These monitors will have telemetry capabilities to enable notification should the set triggers be exceeded.

If the set trigger levels are exceeded, the work activity at the time shall be investigated and if possible the method altered to remove the vibration generating tasks.

Vibration trials may also be conducted prior to out of hours’ vibration-intensive activities that may have significant impact on receptors to gauge potential setback distances or start-up locations.

All data collected by the vibration monitoring units will be reviewed regularly by a suitably qualified person to ensure the Project is not contributing to excessive / unnecessary levels of vibration.


9 COMMUNITY NOTIFICATION

The Community and Stakeholder Engagement Team will conduct designated night works updates prior to all out of hours works commencing. These resident notifications will be communicated to sensitive receivers via email. Sensitive receivers are identified as properties within 100m of the Project boundary. Email notifications will be sent at least 48 hours prior to the works commencing.

In the case of excessively noisy works, where setback distances are greater than 200m (assuming a 37dB assigned level without penalties- see Table 9), residents receiving noise greater than the assigned level will receive notification via letter drop. This is applicable to Task 1, 7, 12, 20 and 30. This notification will be a hard copy of the electronic format provided via email to residents within 100m of the Project boundary. An example notification letter is provided in Appendix D.

Should the City of Cockburn receive more than two complaints within 24 hours from a stakeholder, local community member or business, the notification range will be extended to that identified in Table 9 and additional resident notifications will be issued via letter drop.


10 COMPLAINTS

All complaints shall be handled in accordance with the AAA Community and Stakeholder Engagement Management Plan. Where a noise or vibration complaint is received, AAA shall respond to the complaint and notify MRWA within 24 hours of receipt of complaint. The complaint will also be recorded in the MRWA customer relationship management database, Connect (refer to Table 14 below regarding noise and vibration complaints and contingency actions).

Stakeholders can contact the MRWA Customer Information Centre (CIC) on 138 138 with complaints. The CIC operates 24 hours a day. All complaints will be entered into Connect and be responded to by the AAA Community and Stakeholder Engagement Team (CSET).

For complex or intrusive works, the contact phone number of the rostered site supervisor will be provided to the CIC if urgent information is required. All other enquiries and complaints will be handled via the process outlined above. Enquiries and complaints may also be received via the [email protected] address and directed to the AAA CSET via Connect.

Should a complaint be received as a result of the out of hours works, the cause of the complaint and compliance with the predicted noise and/or vibration levels as defined within this plan shall be investigated. The methodology of works shall also be reviewed to determine any necessary corrective actions and to limit the potential for the works to cause further disturbance.

Where a complaint is identified as being a direct result of a non-conformance or incident, the procedure outlined in Section 11 of this Plan will be followed to allow AAA to identify and amend existing procedures and implement appropriate actions.

Potential contingencies include but are not limited to the actions outlined in Table 14. Where the contingency actions do not resolve the issue, MRWA are to be notified as per section 11.

Table 14 – Noise and vibration complaint contingency actions

Complaint Type Contingency Actions

Noise complaint is received

• Complaint received by CIC and recorded in Connect

• AAA to investigate the source of the noise levels

• Assess the location of monitoring equipment and the need for additional monitoring near origin of complaint

• Respond to complaint and report to MRWA within 24 hours (and to CoC if 2 or more complaints are received)

• Modify the methodology, employ controls i.e. screens, substitute the source of the noise, or stage the works at less disruptive hours of work

Vibration complaint is received

• Complaint received by CIC and recorded in Connect

• AAA to investigate the source of the vibration levels

• Assess the location of monitoring equipment

• Respond to complaint and report to MRWA within 24 hours (and to CoC if 2 or more complaints are received)

• Request vibration monitoring with the landowner at complaint origin

• Modify the methodology, employ controls i.e. dampeners/buffers, substitute the source of the vibration i.e. higher hertz or smaller machinery, or stage the works at less disruptive hours of work


11 NON-CONFORMANCE, INCIDENT AND CORRECTIVE ACTION

Where monitoring confirms the predicted noise or vibration levels (as defined in Table 9 and Section 6) have been met, AAA shall investigate the cause of the exceedance. Where vibration limits are reached, AAA will complete a record of an incident on IMPACT, Laing O'Rourke’s Online Incident Investigation and Reporting Tool. The incident will also be reported through the MRWA electronic incident reporting system, EQSafe. If predicted noise levels are exceeded at a monitoring location this will be recorded as a non-conformance. Where confirmation is possible using additional monitoring as per Table 14 above or reasonably extrapolated to within a residential dwelling or business premise, the exceedance will be recorded as an incident.

All contingency actions taken will be recorded in IMPACT (incidents) and the corrective action register (non-conformances).

Incidents/complaints involving noise and vibration typically involve a complaint from the community, notification by a regulatory authority or non-compliance with an approval or licence condition. These and other typical noise and vibration incidents and appropriate responses are detailed in Table 15 below.
