MELBOURNE METRO RAIL PROJECT: Noise (Construction) & Vibration (Construction & Operation) Expert Witness Conclave –

Environmental Performance Requirements

CONFIDENTIAL & PRIVILEGED [UPDATED - 29/08/2016 10:42:00 AM] Item No.

EPR Current EPR (IAC Version 1) Proposed or Revised EPR (italics = comment / recommendation; standard text = proposed wording)

Agreed or Not Agreed

Discussion

01 EM2 Prepare and implement an Environmental Management System that is certified to ISO 14001:2015 Environmental Management Systems – requirements with guidance for use for construction and operation. Prepare a Construction Environmental Management Plan (CEMP), Site Environment Implementation Plans, Operations Environmental Management Plan (OEMP) and other plans as required by the Environmental Performance Requirements and as relevant to any stage of the project. The CEMP should be prepared in accordance with EPA Publication 480, Environmental Guidelines for Major Construction Sites (EPA 1996).

EPR should be updated to cross reference New NVB (CNVMP) and relevant EPRs. Agreed (DA) No specific EWS recommendations.

02 EM3 Appoint an Independent Environmental Auditor (for PPP contract only) to undertake environmental audits of compliance with the approved CEMP, Environmental Performance Requirements and approval conditions.

EPR should be updated to allow the Independent Auditor access to all materials required to conduct a complete review, including where necessary for sample verification work, access to modelling files, measurement data and supporting test documentation relied upon in the development of design mitigation measures.

Agreed

An Independent arbiter for noise and vibration should be required. Agreed This is addressed in NV14.

03 B3 Following consultation with potentially affected businesses and prior to main works or shaft construction commencing, prepare management plans to minimise dust, noise and vibration impacts during construction, as per AQ1, NV1 and NV4.

EPR should be updated to require a timeline to implement mitigation strategies in sufficient time to enable identified strategies (e.g. 4-6 months)

Agreed (DA) Refer to New NVB.

04 SC2 Prior to main works or shaft construction in areas affected, develop a relocation management framework that responds to the Residential Impact Mitigation Guidelines to ensure allows for a uniform approach across the project for the voluntary (temporary) relocation of households subject to:

Construction activities likely to unduly affect their amenity (e.g. out of hours works or sustained loss of amenity during the day for shift workers)

Loss of access.

Consideration to be given to redefining residential as hotels, commercial residences, residential type uses, hospitals and other spaces used for sleep and rest etc. It is recommended that the RIMG be revised and updated following revision of the other EPRs relevant to construction noise and vibration.

Agreed (DA) Refer to New NVB. Subject to review of RIMG. (All) There is concern with the current draft of the RIMG. It is not considered adequate or appropriate.

2

05 SC3 Prior to main works or shaft construction, develop and implement a Community and Business Involvement Plan to engage potentially affected stakeholders and advise them of the planned construction activities and project progress. This plan should integrate all project activities that potentially impact on community and business operations and provide for a well- coordinated communication and engagement process. The plan must include:

Measures to minimise impacts to the development and/or operation of existing facilities

Measures for providing advance notice of significant milestones, changed traffic conditions, changed access and parking conditions, periods of predicted high noise and vibration activities

Measures for communicating the design and results from environmental monitoring programs (e.g. vibration, noise, dust, ground movement).

Process for registering and management of complaints

Measures to address any other matters which are of concern or interest to them. The plan would consider each precinct and station location in detail. Stakeholders to be considered in the plan include (but are not limited to):

Municipalities

Potentially affected residents

Potentially affected businesses

Recreation, sporting and community groups and facilities

Royal Melbourne Hospital, Victorian Comprehensive Cancer Centre, Peter Doherty Institute and other health and medical facilities

The University of Melbourne

RMIT

Melbourne Grammar

Fawkner Park Children’s Centre and Kindergarten

South Yarra Senior Citizens Centre

Other public facilities in proximity.

To be amended to require that the Residential Impact Management Guidelines (RIMG) are finalised and implemented for the Project. See discussion comment in relation to the RIMG EPR should be updated with a timeline to implement mitigation strategies in sufficient time to enable identified strategies (e.g. 4-6 months) – cross-reference to NV5; Consider adding St Pauls.

Agreed (DA) Refer to New NVB

06 NV1 Manage construction noise in accordance with EPA Publication 1254 Noise Control Guidelines. A number of strong arguments were presented to replace EPA 1254 with

alternative guidelines that prescribed construction noise limits for all time periods, including daytime. The conclave agreed that noise limits recommended in Department of Environment and Climate Change NSW Interim Construction Noise Guidelines (ICNG) or the City of Melbourne Noise and Vibration Management Guidelines (MCC) should be considered. There also needs to be consistency in defining the day, evening and night period. The panel should consider this issue in detail and update the EPR accordingly.

Agreed (TM) In regards to early works, what guidelines, standards etc. are applicable? (SM) Intention of noise limits is to design mitigation to achieve the limit prior to commencing the activities. Facilitates proactive mitigation rather than reactive mitigation. (DA) EPA codes in connection with a framework (e.g. RIMG) provide assurance that all practical measures would be implemented. What is the gap that numerical limits would fill? It would be consistent with Vic practice to retain EPA guidelines. (MSh) (SM) requires numerical criteria, otherwise an impact is not defined. RIMG is irrelevant as works would be programmed during normal working hours or considered unavoidable works where EPA1254 and RIMG do not apply. (MSh) Issue with EPA is it gives a loophole for unavoidable works and subsequent impact to receivers. Does not address the amenity impacts. (PF) (TM) In terms of accountability and impact, it is critical to adopt ICNG or MCC guidelines. (MSt) Adoption of criteria for daytime and UW is important to define unreasonable impact. (TM) biggest concern is definition of UW under EPA 1254. (MDA) The construction plan should also define:

The working periods for key activities that will result in high noise exposure, the measures that have been adopted to limit the duration of these periods, and how working periods will be monitored to avoid unnecessary prolongation of exposure to high noise levels

The measures that will be adopted for the control of impacts related to offsite construction vehicle movements, particularly during the night at site access and departure points in the vicinity of sensitive locations

A clear framework for the implementation of any off-site mitigation measures proposed, prior to commencement of the construction activity in question. This shall included details of consultations and investigations with the affected locations, and verification of the feasibility of implementing the measures proposed.

A program of monitoring to confirm adherence to the plan (WMG) Concern regarding repeated reference to EPA 1254 and allowance for Unavoidable Works to continue without noise restriction. There are no described trigger levels in the EES that would determine when alternative accommodation would be implementation. (TM) Concern regarding the project delays creating impacts outside of permitted hours

07 NV2 For construction works conducted between CBD South station and Domain station, comply with the requirements of the Notification of Referral Decision for the Melbourne Metro Rail Project (EPBC 2015/7549, dated 22 September 2015) under the EPBC Act for vibration monitoring and measurement, as follows:

Conduct pre-construction dilapidation surveys of the nearest Commonwealth Heritage listed structures to the construction activity, including the Former Guardhouse (Block B), to record structural condition and structural integrity prior to commencement of tunnelling

Conduct vibration monitoring at the commencement of tunnelling in geological conditions that are similar to those at Victoria Barracks in order to quantify the actual tunnel boring machine vibration characteristics (level and frequency) for comparison to the values derived from the literature and the German DIN (DIN 4150) target

Conduct continuous vibration monitoring at the nearest Victoria Barracks heritage structures to the construction activity, including the Former Guardhouse (B Block), to assess the actual tunnelling vibration for acceptability, taking into account both the vibration frequency and condition of structures, until monitoring of vibration at the Former Guardhouse (B Block) shows measurements equivalent to preconstruction vibration readings at the Former Guardhouse (B Block)

If monitoring conducted according to the above demonstrates the condition of heritage structures may be degraded as a result of vibration, ground vibration must be reduced by adjusting the advance rate of the tunnel boring machine until monitoring of vibration at the Former Guardhouse (B Block) shows consistent measurements equivalent to preconstruction vibration readings at the Former Guardhouse (B Block).

EPR should to be addressed in the CNVMP as per New EPR NVB.

Agreed (MDA) Prior to commencement of the construction works, a vibration monitoring plan should be submitted for review and approval by the relevant authority. This should include full details of:

vibration measurement methodologies to be adopted for monitoring both baseline and construction levels. This shall include details of the parameters to be obtained, the measurement equipment, parameters to be recorded and relevant standards that shall be adhered to for the collection and analysis of data

baseline and construction vibration monitoring locations

the most critical periods, whether determined by separating distance or ground conditions, and the duration of the monitoring periods.

The requirement of NV2 is also recommended to be extended to apply to Melbourne Town Hall, Melbourne City Baths and St Paul’s Cathedral (AM) The Project should include requirements for a pre-construction condition / dilapidation survey of heritage buildings and potentially vibration sensitive structures at MGS.

5

08 NV3 Appoint an acoustic and vibration consultant to predict construction noise and vibration (through modelling) and update the modelling to reflect current construction methodology, site conditions and specific equipment noise and vibration levels (this will require noise and vibration measurements). The model would be used to determine appropriate mitigation to achieve the Environmental Performance Requirements.

The acoustic and vibration consultant will also be required to undertake noise and vibration monitoring to assess levels with respect to Guideline Targets specified in the Environmental Performance Requirements. Where monitoring indicates exceedances of Guideline Targets, apply appropriate management measures as a soon as possible.

The findings of the modelling and mitigation investigation shall be documented in a Construction Noise and Vibration Assessment Report, which shall provide the basis for the development of the construction management plan required under NV1. The report shall be reviewed by the Independent Auditor (see separate recommended NV concerning the establishment of an Independent Auditor). The report shall implement any recommendations arising from the review prior to being finalised. The EPR should be changed to refer to a “suitably experienced and qualified person”, rather than an “acoustic and vibration consultant”. With respect to the reference to ‘Guideline Targets specified in the Environmental Performance Requirements’ it is recommended that the panel note the comments and recommendations in relation to NV1 regarding strong support for adoption of alternative guidelines for airborne construction noise.

Agreed

(AM) The Project should include requirements for pre-construction background noise monitoring at MGS. (MSh) Noise 1. Noise monitoring during the demolition and construction phases should be conducted throughout the project to confirm both internal and external noise level criteria are achieved. 2. Monitoring should commence prior to commencement of demolition and construction activities to confirm existing base-line noise levels internally and externally. 3. Continuous noise monitoring throughout the demolition and construction phases should be undertaken at the Westin in both hotel and residential apartments as: a. The site is clearly identified as a noise sensitive receivers b. Incorporates both residential and hotel guests c. The proximity of the site to the proposed demolition and construction site d. Assessment and modelling has been based on the proposed acoustic shed being installed. 4. Any monitoring undertaken should be undertaken both internally and externally to confirm compliance with noise criteria given construction works will occur at night. 5. Monitoring should be undertaken within both the residential and hotel room levels closest to the construction site. 6. Noise and vibration monitoring should be undertaken by an independent suitably qualified company at the cost of the Melbourne Metro and provided to the Westin Hotel. 7. An independent review of the design of the acoustic shed should be undertaken prior to finalisation and approval due to the proximity to the Westin and ensuring compliance with acoustic assessment criteria 8. Prior to commencement of 24-hour construction activities located within the acoustic shed it is recommended that a review of the proposed detailing and construction of acoustic enclosure be conducted by an independent suitably qualified acoustic consultant. The review shall confirm that in principle the enclosure will ensure compliance with noise criteria. 9. If noise monitoring during construction indicates that noise emissions exceed nominated noise criteria, then work associated with that activity should cease where practicable and an alternative method of construction be selected prior to the activity re-commencing. If no other option for that specific activity can be undertaken, then hours of operation should be reviewed to minimise impact on residents and hotel guests.

6

(MSh) Vibration 1. Continuous vibration monitoring during the demolition and construction phases in our opinion should be undertaken and in particular it is recommended that monitoring be undertaken at the Westin due to a. The site is clearly identified as a sensitive receiver b. Incorporates both residential and hotel guests c. The proximity of the site to the proposed demolition and construction site d. Assessment and modelling has been based on the proposed acoustic shed being installed. 2. Any monitoring undertaken should be undertaken both internally and externally to confirm compliance with criteria given construction works will occur at night. 3. Monitoring should be undertaken within both the residential and hotel room levels closest to the construction site. 4. Noise and vibration monitoring should be undertaken by an independent suitably qualified company at the cost of the Melbourne Metro and provided to the Westin Hotel. 5. If vibration monitoring (both tactile and ground borne noise) during construction is found to exceed nominated criteria then work associated with that activity should cease where practicable and an alternative method of construction be selected prior to the activity re- commencing. If no other option for that specific activity can be undertaken then hours of operation should be reviewed to minimise impact on residents and hotel guests.

09 NV4 Develop and implement a communications plan to liaise with potentially affected community stakeholders and land owners regarding potential noise and vibration impacts. The plan shall include procedures for complaint management.

As a minimum the communications plan should be developed in consultation with City of Melbourne, City of Stonnington, City of Port Phillip and the EPA Victoria. The plan should also specify precinct-specific community consultations that will be conducted as part of developing, and prior to finalising, the Construction Noise and Vibration Management Plan required under NV-1. Intent of NV4 should be included in New NVB.

Agreed (DA) Refer to New NVB, also EPR B3 and SC3 (AM) The project should include requirements Consultation with MGS in the development of construction noise and vibration mitigation and management measures.

10 NV5 Airborne Construction Noise Guideline Targets (Internal)

Implement management actions if construction noise exceeds the internal noise levels below for Highly Sensitive Areas (based on AS/NZS 2107:2000) and a noise sensitive receptor is adversely impacted.

Highly Sensitive Area

Maximum Internal Construction Noise Level LAeq, 15 mins

Intensive Care Wards 45

Operating Theatres 45

Surgeries 45

Wards 40

A number of strong arguments presented to add consideration to additional sensitive uses. The panel should consider this issue in more detail and provide recommendation in the form of an updated EPR.

Agreed (MDA) This is the only proposed EPR which presently includes proposed Airborne Construction Noise Guideline Targets, However, this EPR does not address external noise levels or residential receiver locations. This EPR should therefore be modified to include Guideline Targets that will apply in accordance with EPA 1254 (i.e. evening and night periods), and should also include recommended Guideline Targets for work during normal hours which would be referenced as part of any requirement to monitor the noise of day-time construction work (see recommended modifications to EPR numbers NV1 and NV3). In relation to the Guideline Targets derived in accordance with EPA 1254, the nominated values must be derived on the basis of the background noise level (LA90 as specified in EPA 1254) in lieu of the higher ambient levels (LAeq) that have been referenced in the EES. Further to the above, the proposed internal targets are not considered suitable for prolonged periods of exposure. AS

7

2107 is primarily concerned with less intrusive types of noise sources such as road traffic. Mitigation measures should therefore be directed at achieving the lower values outlined in AS 2107, Any instances where this cannot be met may be permitted to extend to the upper values that have been presently nominated. It is however expected that concessions to work to the upper levels of AS 2107 would be limited to brief/essential working periods and would need to be clearly identified in the Construction Noise and Vibration Assessment Report recommended in relation to EPR number NV3. The internal targets should also be extended to all other types or relevant non-residential sensitive uses such as offices, schools and hotel accommodation.

8

(MSt) Educational institutions require noise levels be met within occupied spaces such that those spaces can continue reasonably function. (MSH) should include residential receivers. (TM) should this EPR consider all receiver types? (MSt) Proposed Revision Airborne Construction Noise Guideline Targets (Internal) Implement management actions if construction noise exceeds the internal noise levels below for Highly Sensitive Areas (based on AS/NZS 2107:2000) and a noise sensitive receptor is adversely impacted.

Educational institutions (including teaching, research, academic and support spaces)

AS/NZS 2107:2000 satisfactory level plus 5 dB

Notes: 1 The duration of construction noise shall be considered. Acceptable impacts shall be agreed with stakeholders. Mitigation shall be provided in the form of shielding for construction activity and/ or façade improvements where maximum noise levels are expected to be exceeded. 2 Specialist spaces and specific acoustic requirements of spaces shall be addressed depending on their specific requirements. 3 Mitigation to be applied at source in the first instance and then at sensitive receivers where source treatment is not possible. (AM) The airborne construction noise limits recommended by the NSW INCG should be adopted for teaching spaces and office areas within MGS. Specifically, the following noise limits should be applied: i. 45 dB(A) LAeq,15min inside classrooms, teaching spaces and music rooms. ii. 70 dB(A) LAeq,15min outside offices.

11 NV6 Vibration Guideline Targets for Structures

Implement management actions if due to construction activity, the following DIN 4150 Guideline Targets for structural damage

EPR should be updated to require a review of guideline targets following site specific surveys to confirm whether guideline targets are appropriate or require adjustment. The results of the survey need to refine the vibration criteria, where

12 NV7 Undertake condition assessments of above and below ground utility assets and establish construction vibration limits with asset owners.

Monitor vibration during construction to demonstrate compliance with agreed vibration guideline targets. Take remedial action if limits are not met.

Update EPR to include condition assessment and monitoring of vibration during construction at Arden Street Bridge, Swanston Street brick drain, Flinders Street drains, Princes Bridge, Melbourne Town Hall, Melbourne City Baths, St Paul’s Cathedral and utilities (authority and privately owned)

Agreed

1 The Guideline Targets are non-mandatory; they are goals that should be sought to be achieved through the application of feasible and reasonable mitigation measures. If exceeded then management actions would be required.

2 The VDVs may be converted to PPVs within a future noise and vibration construction management plan

EPR to be updated to refer to the relevant Vibration Criteria (VC) presented in ISO Standard 10137:2007 Basis for design of Structures: Serviceability of buildings and walkways against vibration.

Agreed (TM) Reference to VC enables prompt response to exceedances, ID of sources and facilitates rapid action to rectify any exceedance or non compliance, unlike the situation if VDV measured or used

Notes

1 The proponent may undertake consultation with the users and agree alternative Guideline Targets.

In respect to Note 5, the EPR should be updated to include:

A requirement that the design assessment for operational vibration compliance incorporate ground vibration propagation measurements at key locations along the alignment, using a suitable method such as the transfer mobility method described in the FTA Transit Noise and Vibration Impact Assessment Manual (2006).

A requirement that a 5dB safety factor be included in the design assessment for noise and vibration.

A requirement to incorporate a track-form consistent with the Very High Attenuation track described in the EES at locations near vibration sensitive equipment in Parkville and near the RMIT campus at CBD North. The extent of this track-form should address, to the extent that can reasonably be determined at the time of detailed design, the location of future vibration sensitive equipment and activities at the Parkville campus of the University of Melbourne. Sensitive Equipment Guideline Targets Implement management actions if the following ASHRAE equipment vibration Guideline Targets or measured background levels (whichever is higher) are expected to be exceeded for vibration-sensitive equipment during construction and operation for example around the Parkville and CBD North stations.

Agreed (MDA) Micro and nano scale electron-microscopes at Melbourne University and RMIT University are required to operate continuously. Consideration should be given to reducing risk of disruption to experiments by providing secondary vibration isolation to the equipment and adopting sensitive equipment.

(MSt) Sensitive equipment is generally vibration, noise and EMI sensitive. Equipment specific requirements shall be adopted (including testing methodology) where appropriate. A testing and compliance process should be adopted to ensure limits are achieved.

(DA) better to be done as a performance outcome rather than a specification. A modern system should be able to achieve a good outcome with floating track slab in some areas but not all.

(TM) Should have floating track slab throughout the CBD. MDA have done some checks, and with floating track slab there is risk of exceedance at some receivers, within RMIT. Assessment has not used the detailed FTA method.

(TM) RMIT should be included in Note 5, and consistent with the UoM view that the VC’s should be regarded as limits not to be exceeded rather than guideline targets. Issue of secondary isolation should be considered if the criteria cannot be achieved. (JH) Limits should be relevant to the time of use

specifications are expected to be exceeded. Notes 1 The proponent may undertake consultation with the users and agree alternative Guideline Targets. 2 Equipment manufacturer environmental specifications shall be adopted where available, the appropriateness should consider the time of use and background vibration. 3 Background vibration and noise shall be measured in accordance with equipment environmental test requirements. The duration of any periods of higher background shall be considered and not only the highest period. 4 During the construction phase a continuous monitoring program shall be adopted (to stakeholder approval) with online stakeholder access to all monitoring data using a 75% alert and not to exceed limit approach. Monitoring may be carried out at derived locations to agreement with stakeholders to minimise chance of false alerts. 5 Best available track form vibration isolation to adopted to allow future flexibility at the University of Melbourne.

16 NV11 Ground-borne (internal) Noise Guideline Targets for Amenity

Implement management actions as determined in consultation with potentially affected land owners to protect amenity at residences, sleeping areas in hospital wards, student accommodation and hotel rooms where the following ground-borne noise Guideline Targets (from the NSW Interim Construction Noise Guideline) are exceeded during construction.

Time Period Internal LAeq,15min, dB

Evening, 6pm to 10pm 40

Night, 10pm to 7am 35

Notes

1 Levels are only applicable when ground-borne noise levels are higher than airborne noise levels.

2 The noise levels are assessed at the centre of the most affected habitable room.

3 Management actions include extensive community consultation to determine acceptable level of disruption and provision of respite accommodation in some circumstances.

Ground-borne (internal) Noise Guideline Targets for Amenity Implement management actions as determined in consultation with potentially affected land owners to protect amenity at residences, sleeping areas in hospital wards, student accommodation and hotel rooms where the following ground-borne noise Guideline Targets (from the NSW Interim Construction Noise Guideline) are exceeded during construction. Implement management actions where ground-borne noise levels unreasonably limit usage in educational institutions such as lecture theatres. Notes 1 Levels are only applicable when ground-borne noise levels are higher than airborne noise levels. 2 The noise levels are assessed at the centre of the most affected habitable room. 3 Management actions include extensive community consultation to determine acceptable level of disruption and provision of respite accommodation in some circumstances.

Agreed (MDA) The proposed EPR conflicts with the NV1 which commits to manage construction noise in accordance with EPA Publication 1254 Noise Control Guidelines. While EPA 1254 does not explicitly address ground-borne intrusion paths, the advice it provides in relation to night-time work and airborne intrusion paths is to achieve inaudibility within affected receiver locations. For context, ground-borne noise is generally considered more intrusive then airborne noise; this is evident from the lower targets that have been proposed for operational noise intrusion that is dominated by ground-borne noise. It therefore follows that for consistency with NV1 and EPA 1254, the intrusion targets for ground-borne construction noise at night should also be based on achieving inaudibility. If this cannot be practically achieved, alternative limits must be specified in terms of both the duration of the period of exposure as well as intrusion levels set at significantly lower thresholds than have been presently nominated. In terms of the evening Guideline Targets, there is no direct advice in EPA 1254 with respect to internal noise levels. However, while the Guideline Targets for the evening are consistent with the alternative reference guidance in the NSW Interim Construction Noise Guidelines, prolonged construction noise exposure at an internal level of 40 dB LAeq represents a significant risk. Accordingly, ground-borne noise intrusion at the proposed evening level, if permitted, should be specifically restricted to limited periods (e.g. less than 1 week). (AM) ground-borne construction noise limit of 40 dB(A) LAeq,15min should be adopted for teaching spaces and office areas. This aligns with the evening period noise limit for ground-borne construction noise recommended by the NSW INCG. The Project should also include the likely ground-borne construction noise levels at MGS to be determined and appropriate mitigation measures to be implemented. (MSt) Educational institutions require noise levels be met within occupied spaces such that those spaces can continue reasonably function.

Blasting Comply with Australian Standard AS2187.2-2006, Explosives – Storage and use Part 2 – Use of explosives for all blasting For Highly Sensitive Areas, hospital wards, operating theatres and Bio-resources and areas with vibration-sensitive equipment which are not covered in AS2187.2-2006, develop a plan in consultation with facilities owners that: • Avoids damage to vibration-sensitive equipment

Agreed (MSt) Risks associated with Bio-resources mean that mitigation and control require a precautionary approach given the extreme difficulty with mitigation and the lack of consultation options.

15

consultation with facilities owners that:

Avoids damage to vibration-sensitive equipment

Minimises adverse impact on Highly Sensitive Areas and Bio-resources.

• Minimises adverse impact on Highly Sensitive Areas and prevents impact on Bio-resources. Notes 1 A precautionary approach shall be taken for Bio-resources to ensure no impact from blasting. 2 Vibration at sensitive equipment shall be not exceed levels which would require recalibration.

18 NV13 To protect the amenity of Bio-resources and sensitive research during construction and operation, the following criteria apply:

Background noise should be kept below 50 dB and should be free of distinct tones (internal)

Short exposure should be kept to less than 85 dB (internal).

Notes

1 The levels above should take into consideration the frequency threshold for the Bio-resource under consideration.

2 Higher levels may be acceptable if it can be shown that the Bio-resource under consideration is exposed to higher levels and is not adversely impacted by them.

To protect the amenity of Bio-resources and sensitive research during construction and operation, the following limits apply: • Background noise should be kept below 50 dB Leq and should be free of distinct tones (internal) • Short exposure should be kept to less than 85 dB Lmax (internal). Notes 1 The levels above should take into consideration the frequency threshold for the Bio-resource under consideration. 2 Higher levels may be acceptable if it can be shown that the Bio-resource under consideration is exposed to higher levels and is not adversely impacted by them. 3 Noise includes airborne and structure borne. 4 A precautionary approach shall be taken for Bio-resources to ensure no impact from construction noise and vibration. 5 Background shall be measured in accordance with Bio-resource standards. The duration of any periods of higher background shall be considered and not only the highest period. 6 A continuous monitoring program shall be adopted (to stakeholder approval) with online stakeholder access to all monitoring data. 7 Consideration given to adopting a vibration limit in agreement with MMRA and stakeholders

Agreed (MDA) The proposed EPR is generally considered reasonably but should be clarified in terms of the measurement parameters and measurement durations that apply to background noise and short exposures, including citation of the relevant references for the selected thresholds. (MSt) Risks associated with Bio-resources mean that mitigation and control require a precautionary approach given the extreme difficulty with mitigation and the lack of consultation options. (MSt) Vibration levels shall be kept to less than 75 micro-m/s (VC-A plus 50%).

19 NV14 Appoint an acoustic and vibration consultant to predict noise and vibration and determine appropriate mitigation to achieve the Environmental Performance Requirements. The acoustic and vibration consultant would also be required to undertake commissioning noise and vibration measurements to assess levels with respect to the Environmental Performance Requirements.

The EPR should be updated to require that the noise and vibration consultant shall prepare the Construction and Operational Noise and Vibration Reports for review and approval by the Independent Auditor commissioned to review the predictions and proposed design mitigation measures.

Agreed (MDA) In contrast to the Governance Framework outlined in Chapter 23, the Independent Auditor should not be appointed jointly by the MMRA and PPP. It is recommended that the Independent Auditor should be selected and engaged by the Department of Transport, Planning and Local Infrastructure, with costs borne by the MMRA and/or PPP contractor. The Independent Auditor should also be granted access to all materials required to conduct a complete review, including where necessary for sample verification work, access to modelling files, measurement data and supporting test documentation relied upon in the development of design mitigation measures

Notes

1 RING provides trigger levels for residential and schools, educational institutions and places of worship, but does not provide guidance on acceptable ground-borne noise levels for other types of sensitive receivers. Ground-borne noise trigger levels for other types of sensitive occupancies have been devised based on RING and industry knowledge.

2 Specified noise levels refer to noise from heavy or light rail transportation only (not ambient noise from other sources).

3 Assessment location is internal near to the centre of the most affected habitable room.

4 LASmax refers to the maximum noise level not exceeded for 95% of the rail pass-by events.

5 For schools, educational institutions, places of worship the lower value of the range is most applicable where low internal noise levels is expected.

6 The values for performing arts spaces may need to be reassessed tohe specific requirements of a venue.

The wording of EPR NV17 should be strengthened to make the proposed target criteria for operational ground-borne noise and vibration mandatory.
