J1. INTRODUCTION

This Construction Noise and Vibration Management Plan (CNVMP) forms part of a suite of environmental management plans within the Construction Environmental Management Plan (CEMP).

This CNVMP identifies the noise and vibration performance standards that must, where practicable, be complied with. It also sets out best practicable options for noise and vibration management for the Project. This CNVMP is intended as a framework for the development and implementation of particular noise and vibration management and control methodologies to minimise adverse effects on health and safety of workers and occupants and to reduce the adverse impact on the environment.

This CNVMP will be updated throughout the course of the Project to reflect material changes associated with any changes to the construction methodologies or techniques or the natural environment. The document shall be reviewed annually to ensure that any changes are reflected.

A Glossary of technical terms is contained in Appendix A.

J9. MONITORING

J9.1 Requirements

J9.1.1 Noise

Construction noise levels shall be monitored and assessed in accordance with the requirements of NZS 6803:1999 “Acoustics - Construction Noise”.

Construction noise levels shall be monitored and assessed:

Generally in accordance with NZS 6801:2008 and NZS 6803:1999

During critical phases of construction, i.e. when possible exceedance of the Project criteria is anticipated

In response to reasonable noise complaints being received

At locations representative of sensitive receivers in the vicinity

One metre from the most affected façade, or, if this position is not accessible, at an equivalent position where practicable. If this is not possible, measured noise levels shall be adjusted for distance and façade reflections if necessary

To reflect representative construction activities, and shall be no less than 10 to 15 minutes and not exceed 60 minutes duration. The measured noise level shall be stated with the measurement duration: LAeq(T)

By a suitably qualified acoustic specialist

J9.1.2 Vibration

Construction vibration levels shall be monitored and assessed in accordance the requirements of German Standard DIN 4150-3:1999 “Structural vibration – Part 3: Effects of vibration on structures”.

Prior to construction, trial measurements of high-vibration activities (including blasting) shall be undertaken to establish Project specific ground attenuation characteristics and safe distances.

During construction, vibration levels shall be monitored and assessed:

During critical phases of construction, i.e. when possible exceedance of the Project criteria is anticipated

In response to reasonable vibration complaints being received

To reflect representative construction activities, and shall comprise measurements of peak particle velocity (PPV) at one second intervals

By a suitably qualified and experienced specialist

J9.2 Contingency measures

In the event that measurement shows non-compliance with the Project criteria, the following procedures shall be implemented:

For noise, the processes of the flow chart attached in Appendix B shall be followed. This includes further measurement to be undertaken where necessary to determine the



extent of non-compliance and preparation of a report outlining the non-compliance and, if required, potential mitigation and management measures

For vibration, the processes of the flow chart attached in Appendix C shall be followed. This includes a building condition survey and a report prepared by a suitably qualified person, including photographs, detailing the state of repair of the existing structure, and an opinion as to whether any damage may be due to construction activity. Subsequent additional monitoring and other management as required. Upon implementation of any additional mitigation measures, further measurements shall be undertaken to confirm the effectiveness of those mitigation measures

J9.3 Reporting

Any noise, vibration or building condition surveys shall be summarised in a report to be submitted to the Project Manager within one week of the assessment. Monitoring records shall be kept at the site office and made available upon request.

J10. GENERAL MANAGEMENT PROCEDURES AND MITIGATION MEASURES

The following sections outline noise and vibration management and mitigation measures that shall be implemented throughout construction of the Project.

Any appropriate management and mitigation measures shall be implemented and installed in the appropriate locations prior to the construction works occurring that have been identified to potentially cause an exceedance of the Project criteria set out in Section J3 above.

J10.1 Consultation

Consultation with affected parties shall be carried out prior to commencement of construction activities as follows:

Receivers within 100 metres of the construction area: Written notification and a Project description shall be provided to raise awareness of the Project, its expected activities and duration in the vicinity

Receivers within 50 metres of the construction area: Individual written notification shall be provided and opportunity made available for discussions on a case-by-case basis, if requested by the occupants/owners

Receivers within 20 metres of the construction area: Individual discussions shall be held and, if required, suitable alternatives and/or mitigation options explored that are acceptable to both parties. Ongoing consultation shall be carried out throughout the duration of construction

When discussing concerns over vibration, it is important to convey that vibration can be felt at levels far below those that pose a risk of building damage.

Further details on identifying at-risk receivers are contained in the Schedules in Appendices D and E. [Schedules of at-risk receivers shall be completed by the contractor prior to commencement of the Project].



J10.2 Training of personnel

All personnel on site shall be made aware of the importance of operating in the least disruptive manner. All personnel working on the Project, including Contractor employees and subcontractors, shall be familiar with, and be responsible for, implementing this CNVMP.

J10.3 Schedules of At-risk Receivers

Prior to commencement of Project construction operations, at-risk receivers, structures and buried services shall be identified and added to the schedule in Appendix D.

At-risk receivers may include places of work or assembly where people may be annoyed by construction noise or vibration, e.g. Aotea Centre where the building is not at risk but people attending performances may be adversely affected.

J10.4 Building Condition Surveys

Prior to the commencement of Project construction operations, a detailed pre-construction building condition survey of identified at-risk structures and services (refer Schedule in Appendix D) shall be conducted by a suitably qualified engineer. In addition, each building shall be classified according to the Project vibration criteria (refer Section 0) to identify the relevant vibration limit for that receiver.

The survey shall include, but not be limited to, the following:

Existing condition of buildings, services or structures, including existing levels of any aesthetic damage or structural damage

Record (including photographs) of the major features of the buildings, services and structures including location, type, construction, age and present condition, including defects

Foundation type of the building, service or structure

Preparation of a report recording the findings of the survey. A copy of each report shall be forwarded to the Contractor Environmental Manager and kept at the site office

Resurvey of buildings, services and structure, during construction, which are the subject of complaints, or if the vibration criteria have been exceeded and there is potential for damage to have occurred

Within six months of completion of the Project, a detailed post-construction condition survey of the same buildings, services and structures shall be conducted and a report prepared

10.1 Reversing Alarms

All equipment operating on any of the above ground Project construction sites during night-time shall be fitted with alternatives to tonal reversing alarms. These may be flashing lights or broadband audible alarms.



J10.4 Night-time Operation

In close proximity to residences, above ground high-noise and/or vibration activities shall be scheduled for daytime where practicable, and avoided during night-time

In close proximity to commercial buildings, high-noise and/or vibration activities shall be scheduled for evening and night-time periods where this is practicable

J10.5 Noise Barriers and Enclosures

Shall be used in areas where the Project noise criteria may be exceeded

Shall be used where they provide effective mitigation (i.e. break acoustic line-of-sight and are close to either the source (preferable) or the receiver)

Barriers are typically constructed from plywood and shall contain no gaps and be of sufficient height to interrupt line-of-sight between the receiver and the source. Alternative barrier constructions may include, but not limited to, fibre cement, shipping containers or mass-loaded vinyl

Enclosures may be used where a noise barrier is not sufficient to achieve compliance with the Project noise criteria

Enclosures may be used where practicable, i.e. stationary plant such as conveyors or crushers

Enclosures shall be designed by a suitably qualified and experienced acoustic specialist

All barriers and/or enclosures shall be installed in relevant positions prior to those construction works occurring that have been identified to require mitigation

J10.6 Mechanical Ventilation of Dwellings

Where external windows must be closed in order to achieve compliance with the internal Project noise criteria, and where no alternative ventilation system is present, the installation of mechanical ventilation shall be considered for that building. This shall be implemented as a last resort only after all other general noise management and mitigation have been deemed impracticable.

J10.7 Selection of low noise and vibration plant

Low noise and vibration plant shall be selected and used wherever practicable. Where plant is identified as being particularly noisy and/or vibration inducing, action shall be taken to reduce emissions. This may involve the fitting of mitigation devices, such as silencers, enclosures or isolation pads. Plant shall be maintained to ensure that noise and vibration emissions remain as low as practicable.

J10.8 Vibration Effects on Infrastructure Assets

Any infrastructure assets such as roads, underground pipework etc. near areas of high-vibration activity shall be identified prior to commencing construction and included as the Schedule in Appendix D.

Risk assessments of relevant infrastructure assets shall be undertaken, and be managed through SSCVMPs (refer Section J11) as appropriate.



J10.9 Temporary relocation

Where all practicable noise and vibration management and mitigation measures have been implemented, but compliance with the Project criteria is still not achievable, relocation of affected receivers may need to be considered.

Relocation shall be considered in exceptional cases only, and expert advice from a suitably qualified and experienced acoustics specialist shall be sought.

J11. SITE SPECIFIC CONSTRUCTION MANAGEMENT PLANS (SSCMPS)

J11.1 Site specific construction noise management plan (SSCNMP)

For any construction activities that have the potential to breach the noise criteria, as set out in Section J3, a noise assessment shall be undertaken.

Where noise levels are predicted to exceed the noise criteria in Section J3 by less than 5 dBA, all practicable measures will be implemented as per the CNVMP with the aim of achieving compliance with the construction noise criteria. Monitoring of these activities will be undertaken to determine compliance. Where the modelled noise levels are predicted to be 5 dBA or more above the noise criteria in Section J3, a SSCNMP shall prepared prior to works commencing.

J11.2 Site specific construction vibration management plan (SSCVMP)

For vibration issues, a SSCVMP shall be developed for any activities measured or predicted to exceed the building damage Project criteria, refer Section 0.

J11.3 General requirements

Notwithstanding the requirement to submit a SSCNMP or SSCVMP, mitigation measures shall continue to be implemented as per the CNVMP and reviewed/monitored to confirm compliance and effectiveness of the plan. This includes the overall aim to achieve compliance with the relevant Project criteria.

For noise, the likelihood of exceedance shall be determined by utilising appropriate prediction tools.

For vibration, the likelihood of exceedance shall be determined by pre-construction measurements of relevant vibration inducing equipment to establish safe distances.

The SSCMPs shall contain, to an appropriate detail:

The activity and location proposed

Timing/duration

Equipment utilised

Predicted noise/vibration levels

Identified dwellings at which compliance cannot be achieved with conventional mitigation measures

Alternative management and mitigation measures proposed



J12. CONSTRUCTION NOISE AND VIBRATION MANAGEMENT SCHEDULES

Management schedules for construction noise and vibration shall be prepared for each area of works (refer Section J5 above).

The vibration schedule (Appendix D) shall detail high-vibration equipment, their safe distances and all sensitive receivers within the high and medium risk categories.

The noise schedule (Appendix E) shall detail high-noise equipment and all sensitive receivers as follows:

For daytime work: within the 20 metre and 50 metre categories, and

For night-time work: within the 20 metre, 50 metre and 100 metre categories

The schedules shall be completed prior to commencement of construction works in each Sector.

J13. SPECIFIC MANAGEMENT AND MITIGATION
