4 ENVIRONMENTAL POLICY AND COMMITMENTS This Project NVMP is based on WBHO’s is ISO 14001 certified Environmental Management System and accordingly, any reference to WBHO documents or procedures will correspondingly apply to the H2H project. (See Appendix 1)
The Environmental policy (HSEQ Policy) reflects our commitment to ISO 14001 and will ensure:
The policy is appropriate to the purpose and context of the H2H project and supports its strategic direction; It provides a framework for setting environmental objectives; Includes a commitment to satisfy applicable requirements and legislative approval across the project; Includes a commitment to continual improvement of the Environmental management system. The policy and commitment statement are supplied to each of the subcontractors; The Policy guidelines are part of the environmental induction; and The policy will be displayed on all noticeboard across the project site.
5 Objectives & Targets In alignment with MRWA scope 4.14(b), noise level objectives are specified as upper limits of traffic noise that apply outside residential buildings and other noise sensitive land uses (as defined in Western Australian Planning Commission State Planning Policy 5.4). They are listed in the construction noise table 2 below. Due to the impracticality of controlling noise at the upper floors of multi-storey buildings, noise assessment is restricted to the ground floor levels. The noise level objectives in Table 1 will be achieved, with a maximum height of noise barriers of 5.0 m. (MRWA Scope 2021)
Environmental objectives and targets are defined in the Australian/New Zealand Standard AS/NZS ISO 14001: 2004 as:
Environmental Objective: “Overall goal, consistent with the environmental policy, that an organisation sets itself to achieve” Environmental Target: “Detailed performance requirement, applicable to the organisation that arises from the environmental objectives and that is decided and then achieved to enable the project to meet those objectives”
The objective of this plan is to provide a Noise & Vibration Management Plan (NVMP) to align with:
MRWA Scope requirements 9.4(j)(ii) and 9.4(k)(i) as presented within the MRWA Scope of Works document; AS/NZS 2436-2010:2016 Guide to noise and vibration control on construction, demolition and maintenance sites; and Legislative guidelines.
Document No.: 39021-ENV-PL-003 - Issue Status: 2 Page 11 of 28 Date of Issue: 03 Aug 2021 Main Roads Western Australia (MRWA) Mitchell Freeway Southbound Upgrade - Hodges Drive to Hepburn Avenue
As per MRWA scope requirement 9.4(j)(ii) and 9.4(k)(i), this NVMP outlines the management requirements that will be utilised to address potential construction noise and vibration issues at the proposed Mitchell Freeway Southbound Upgrade – Hodges Drive to Hepburn Avenue Project.
This NVMP will be managed in conjunction with the H2H Environmental Management Plan (EMP) that defines the overall project requirements.
Related project management plans include:
Integrated Management System (IMS) Manual, 59003-HS-PL-001; The Health and Safety Management Plan; and WBHO 59003-QM-PL-001 Quality Management Plan.
One of the key objectives during project works is to avoid noise exceedance or vibration levels as specified in Table 2. H2H will comply with the Environmental Protection Act 1986 (WA), Environmental Protection (Noise) Regulations 1997 (WA) and endeavour to minimise any disruption to public receptors throughout the project. Vibration levels will not exceed 5mm/s during project works.

7 KEY IMPACTS H2H have assessed the project based on the MRWA project scope and provided a risk assessment as provided in Appendix 2 – Key Environmental Aspects and Management. This register identifies the impacts and controls that will be implemented to mitigate those impacts and the residual risk after controls are implemented.
Management Actions- H2H recognises that to minimise environmental impacts it is important to identify the link between various construction activities and the potential for these activities to impact the environment. The environment is defined as “living things” a physical, biological and social surrounding and describes the interaction between all of these things.
Construction activities undertaken by H2H will be in accordance with state and commonwealth environmental legislation and site-specific environmental aspects identified by H2H. The management measures described, refer specifically to site Noise & Vibration sources that may impact surrounding dwellings and infrastructure.
7.1 Noise & Vibration Plan Overview The NVMP’s focus, is to monitor, minimise or eliminate disturbance to local residents and surrounding dwellings through the use of engineering controls. Noise mitigation controls can be in the form of continuous monitoring, adaptive construction methodologies including the use of specifically designed structures (temporary noise walls).
Main Roads Western Australia (MRWA) Scope conditions outline the parameters, regulations and guidelines that this NVMP will comply to and accordingly is described in the remainder of this document.
7.2 Construction Noise Management The H2H construction site runs adjacent to noise sensitive receptors, and subsequently the below noise level construction site noise parameters are applicable to the project. Noise pollution can have an adverse effect on public places specifically in areas close to the constructions project. Reducing noise at source is the initial objective and the first stage of noise pollution mitigation.
It is noted that the NVMP will align with the environmental standards of the Local Government Authorities (LGA), in this case The City of Joondalup, The City of Wanneroo & The City of Stirling.
Noise levels objectives for the project have been specified as upper limits of traffic noise levels that apply outside residential buildings and other noise sensitive land uses. Noise level objectives in Table 2 must be achieved, with a maximum height of noise barriers of 5.0 m. (MRWA 2020).
Document No.: 39021-ENV-PL-003 - Issue Status: 2 Page 14 of 28 Date of Issue: 03 Aug 2021 Main Roads Western Australia (MRWA) Mitchell Freeway Southbound Upgrade - Hodges Drive to Hepburn Avenue
Table 2 Construction Site Noise Parameters: AS/NZS 2436-201:2016
Time Period Base Objective
Day (16 hour) L 60 dB(A) 6:00am to 10:00pm Aeq
Night (8 hour) L 55 dB(A) 10:00pm to 6:00am Aeq
The above noise levels will be assessed 1.0m from a building, 1.4m above ground level. The noise levels will be recorded to the nearest 0.1dB(A) and then rounded to the nearest 1 dB(A) for reporting and assessment purposes.
As stated in MRWA Scope of Works Clause 8.1(a), Except as required by Law the maximum working hours permitted must be between 7:00 am and 7:00 pm, Monday to Saturday, except that work outside these hours may be permitted for specific operations subject to the approval in writing of the Project Manager and compliance with the noise limits objectives MRWA clause 4.14(b)(ii). No work will be allowed on public holidays except as permitted by Law and then only with the prior approval in writing of the Project Manager.
In the event of night works, noise generation will be of major considerations prior to works being approved. Works that produce excessive noise will be minimised where possible outside of general working hours. These works will be discussed with the Main Roads Project Manager prior to commencing and works will be planned to minimise noise impacting the surrounding area.
H2H will ensure plant and equipment is maintained on a regular basis as far as practicable and in particular ensure factory fitted noise controls are in good working order (e.g. exhausts silencers, comply with occupational health and safety standards); no servicing of machines will occur outside normal working hours.
7.3 Noise Monitoring Noise monitoring will be utilised, if required, to compare with pre-works noise baseline monitoring levels. The testing method will comply with section 5 of AS 2436-2010. All noise measuring equipment will comply with Schedule 4 of the Environmental Protection (Noise) Regulations.
Areas where noise levels exceed the specified site values may require erection of temporary noise barriers, should the above compliance mitigation measures not be sufficient. Where there are concerns around noise levels, then noise monitoring will be undertaken. Noise monitoring will be conducted using sound level meters which meet or exceed requirements of AS IEC 60942-2004 Electroacoustics- Sound calibrators, for class 1 or class 2 sound sources, as the case requires (Schedule 4 of EP Noise Regs).
Traffic noise measurement will be carried out in accordance with Main Roads’ Noise Measurement Specification in Appendix 3. The location of noise measuring equipment must be approved by the MRWA Project Manager before the Hold Point is released.
Document No.: 39021-ENV-PL-003 - Issue Status: 2 Page 15 of 28 Date of Issue: 03 Aug 2021 Main Roads Western Australia (MRWA) Mitchell Freeway Southbound Upgrade - Hodges Drive to Hepburn Avenue
Noise monitoring will be conducted in compliance with the Environmental Protection Act 1986 (WA) and the Environmental Protection (Noise) Regulations 1997 (WA). Where the extrapolated noise levels exceed the Noise Level Objectives, H2H will undertake remedial works that will result in compliance.
Other mitigation measures that will be employed by H2H include:
Limiting works in sensitive areas to the permitted normal working hours; Ensure the exhaust silencers and mufflers are in good working order and comply with OH&S standards; The use of reduced speed limits on temporary trafficable surfaces; Undertaking fabrication work off-site where possible; Use of material/mulch stockpiles as temporary noise barriers; Erection of permanent noise walls as soon as possible; and Distancing work away from existing dwellings where possible, (e.g. mulching cleared material or mechanically mixing of material).
7.4 Noise Measurement H2H will measure existing noise levels prior to the commencement of the Project Works. H2H will measure noise levels six months after Completion of section 2 and the removal of traffic management on the main carriageway, and the results extrapolated to the design year, to report on the effectiveness of noise control measures and to ensure compliance with the Noise Level Objectives; Noise measurement will be implemented in accordance with MRWA Specification; The location of noise measuring equipment will be approved by the Project Manager before the Hold Point is released; and Where the extrapolated noise levels exceed the Noise Level Objectives,H2H will undertake remedial works which will result in compliance.
7.5 Sensitive Receptors Noise-sensitive land-use and/or development: This is generally determined by land-uses or development as zoned by a local planning scheme or structure plan that is occupied or designed for occupation or use for residential purposes. The H2H project areas of noise and vibration impacts will include: Dwellings, residential buildings (local community); Short-stay accommodation; Caravan parks; Sports grounds and recreation centres; Educational establishments, (Schools/ Colleges and Universities); Child-care premises; Hospitals and care facilities; Nursing homes; and Places of worship.
Document No.: 39021-ENV-PL-003 - Issue Status: 2 Page 16 of 28 Date of Issue: 03 Aug 2021 Main Roads Western Australia (MRWA) Mitchell Freeway Southbound Upgrade - Hodges Drive to Hepburn Avenue
7.6 Vibration Management Excessive vibration may cause disturbance to existing infrastructure in the form of structural change. In some instances, impulsive vibration may be a triggering mechanism that may result in the failure of s building/structural components, that have previously been in a stable state.
Therefore, it is necessary to conduct a property condition survey prior to work commencing, as per MRWA Scope section 9.4(l). The survey will be performed by a third party independent, qualified assessor and approved by MRWA. Any subsequent investigations will be performed by the same individual.
All properties within 100m of the construction zone will be surveyed. The dilapidation survey will be completed for each property and records maintained with the status for each survey.
The report for each property will contain the following:
Reference number, address, type of dwelling and date assessed; Properties of heritage significance Summary of the property type and condition; Detailed assessment of the property, including photos and descriptions specifically noting any defects or damage to the property; and Photos of any damage in particular.
In accordance with MRWA Scope clause 9.4(I)The survey will be carried out within the extent of the area that may be affected by the activity. As a minimum the extent of the property condition survey will include:
All properties within 100 m of any construction activities; Any nearby properties of heritage significance; Existing railway stations at greenwood, Whitfords and Edgewater; and Existing bridges and retaining walls within 20 m of construction works.
A copy of the report will be maintained on the project folder and provided to the homeowner for reference.
At the completion of the H2H project each property owner will be provided the opportunity to request a follow up survey to assess if damage has occurred on the property as a result of the project works.
To minimise the risk of damage to surrounding properties, H2H will limit ground vibrations by ensuring that the ground particle velocities from any necessary operation including vibratory compaction or percussion equipment use cause minimum impact and do not exceed statutory limits that could result in damage to property. Vibration levels will be limited to a 5 mm/s limit.
Low vibration or non-vibrating construction methodologies will be adopted during construction activities close to adjoining properties.
Document No.: 39021-ENV-PL-003 - Issue Status: 2 Page 17 of 28 Date of Issue: 03 Aug 2021 Main Roads Western Australia (MRWA) Mitchell Freeway Southbound Upgrade - Hodges Drive to Hepburn Avenue
In alignment with MRWA Scope cluse 9.4(k): A baseline vibration measurement will be taken in two locations and within a nominated time by the supervisor and will coincide with the commencement of works involving the vibratory compaction and percussion equipment.
H2H suggest that the baseline vibration monitoring should take place in areas adjacent to where the staged construction activities are due to commence.
A map that details the location of the monitors will be produced once determined and agreed with the Main Roads Project Manager. This map will be located within the project office on site.
H2H will continuously monitor vibration levels during construction activities involving the operation of vibratory or percussion equipment. The monitoring equipment will be moved to at least two locations depending the construction works schedule. The monitoring equipment will have Real Time measuring capability and notification, when predetermined vibration limits are exceeded.
Furthermore, the equipment will provide a copy of measurements for each month, and will be submitted to MRWA supervisor, as stated in 9.4(k) of the project Scope.
If a complaint is issued by a resident, H2H will inform MRWA of the complaint and issue a response at the earliest opportunity and no later than 24 hours after the complaint was received. In addition, H2H will take vibration measurements at the impacted residence. If the vibration limits are greater than 5mm/s, limits, H2H will modify the construction method to reduce vibration impacts.
7.7 Exceedance of Vibration Limits If a scenario arises where the allowable vibration limit is exceeded, an alert will be sent via email/text message to site Engineers and the following actions will take place:
Works involving vibrating or percussion equipment, adjacent to the impacted area will cease, until a less destructive method of construction is found; The construction methodology will be revised, and alternative means of ground compaction will be investigated; The compaction equipment may be swapped out for a low/micro vibration or oscillation compactor. These machines are specifically designed to minimise the adverse effects of vibrations to the surrounding structures / environment; Should any unplanned settlement occur due to vibration then works will be stopped and an alternative method will be developed and trialed to ensure compliance; When an alternative methodology is agreed upon and approved by the H2H Project Manager, a trial run will take place in the previously impacted area, with the monitoring equipment in place, to clarify that the new methodology does not exceed the specified vibrations limits; and If/when the alternative methodology has been deemed satisfactory by the H2H Project Manager, any further works involving vibration or percussion equipment in the area will be closely monitored, until that particular activity/task has been completed.

7.8 Stakeholder Engagement & Complaints H2H will advise the Project Manager and respond to any complaint at the earliest opportunity if received from local residents, but no later than 24 hours after the complaint is received. In addition, H2H will take noise or vibration measurements at the affected residence. If regulatory vibration limits are exceeded, H2H will endeavour to modify the construction method to reduce vibration.
The Community and Stakeholder Engagement Plan will detail response times that are compatible with the Main Roads’ Customer Service Charter. H2H will use the Main Roads’ corporate customer relationship management (CRM) system, CONNECT, and align the management of such enquiries to the Main Roads’ corporate processes.
Prior notification of construction activity impacts including noise and amenity walls and night works will be given to residents and H2H will determining the appropriate community and stakeholder engagement processes for enabling and considering community and stakeholder input into specific noise and vibration issues.

Appendix 4 Traffic Noise Measurement Specification (MRWA APPENDIX 23)
1. General
Noise measurement will involve:
. Measurement of noise on private property. . Use of calibrated equipment. . Verification of data. . Collection of site information, including photographs. . Comprehensive reporting of results. . Supply of digital data (noise levels, site information, photographs). . Provision of maps indicating locations of measurement sites.
The basic requirement is that measurement and equipment complies with AS 2702 Acoustics - Methods for the Measurement of Road Traffic Noise.
2. Microphone Position
The microphone is to be placed in the standard position of 1 metre from the building facade which faces the major road and 1.2 to 1.5 metres above ground floor level. This may necessitate the microphone being set high when compared to ground level in any cases where residences are on high foundations or stumps.
The microphone is to be no closer than 1 metre from any corner of the building and is not to be placed adjacent to an opening window.
3. Noise Measuring Equipment
Equipment is to have been subject to:
. A laboratory calibration within the last 24 months; and . A very recent performance check.
4. Monitoring Period
Hourly noise levels are required for a minimum of three 24-hour normal weekdays. Any noise measurement results for weekends, public holidays or school holidays are outside the scope of this brief and are not to be included in summary tables or the main body of the report.
Document No.: 39021-ENV-PL-003 - Issue Status: 1 Page 26 of 28 Date of Issue: 26 July 2021 Main Roads Western Australia Mitchell Freeway Southbound Upgrade - Hodges Drive to Hepburn Avenue 5. Weather Conditions
During noise monitoring, the road surface is to be dry and wind conditions will be typical/neutral so as to provide valid noise measurement results. Evidence is to be supplied to confirm compliance with the specified acceptable wind conditions. Rain or unacceptable wind for several hours over the 24-hour period will not necessarily invalidate the daily measurement, but relevant comment is required. Acceptable wind conditions are specified below. Positive wind blows from road to residence, variable wind is considered to be a typical am/pm split of positive and negative winds.
(a) Microphone-road distance up to 20 metres:
(i) variable wind during a 24-hour period up to 19 km/h; or (ii) calm conditions, or continuous positive wind up to 19 km/h.
(b) Microphone-road distance greater than 20 metres:
(i) variable wind during a 24-hour period up to 19 km/h; or (ii) calm conditions, or continuous positive wind up to 11 km/h.
6. Data Verification
Data is to be verified by inspection and professional judgement. Any occasional hourly data considered to be atypical should be replaced by an estimated value. This estimated value is to be in bold italics and an explanatory note is to be placed in an appropriate position.
7. Site Information
For each measurement site detailed information is required, including conditions affecting levels of noise.
Two photographs of each site are required showing:
. Microphone position – so that any future measurement may be made with the microphone in the identical position.
. Road layout – panorama showing overall layout of the major road, and ideally the measurement site in the background indicating how it is situated in relation to the road.
Document No.: 39021-ENV-PL-003 - Issue Status: 1 Page 27 of 28 Date of Issue: 26 July 2021 Main Roads Western Australia Mitchell Freeway Southbound Upgrade - Hodges Drive to Hepburn Avenue
8. Results
Hourly Data – Results of noise measurements are to list hourly values of L1, L10, Leq and L90, in tabular and graphical form.
Daily Results – A separate table listing all sites, indicating the four daily values of L10(18 hour), Leq(24 hour), Leq(16 hour) 6am to 10pm, and Leq(8 hour) 10pm to 6am on the same date, with levels rounded to 0.1 dB(A). This table will include an average value of the four daily results, rounded to whole numbers. Site number, address and dates will be included.
9. Electronic Versions
Electronic versions of information are to accompany the final report:
. Site information (MS-EXCEL format). . Noise measurement data (MS-EXCEL format). . Photographs in JPEG format, one photograph per file. 10. Report
The noise measurement report will include:
. Procedures used in noise measurements. . Measurement site information, including photographs.
. A summary of the results and a map of the project showing measurement site distribution. . Appendices containing noise level data (in table and graph form) and weather data. . Street Smart maps (1:20000) indicating the location of each measurement site.
