Construction Noise and Vibration Delivery Work Plan
Introduction The City Rail Link (CRL) project comprises the construction, operation and maintenance of a 3.4 km underground passenger railway, running between Britomart Station and the North Auckland Rail Line in the vicinity of Mt Eden Station. The CRL also involves the construction of two new underground stations at Aotea and Karangahape and the redevelopment of the station at Mt Eden (refer to Figure 1.1). The design and construction of the CRL infrastructure between the Aotea and Mt Eden Stations is being delivered by the Link Alliance.
Figure 1.1 CRL Route and Location
This Construction Noise and Vibration Delivery Work Plan (CNV DWP) has been prepared in relation to construction of the new Aotea Station.
1.1 Aotea Station Overview Aotea Station is 15m-deep by 300m-long, involving a cut-and-cover method of construction. The Aotea Station will include platforms, lifts, escalators, rooms for housing stations and tunnel services equipment, entrances at Victoria and Wellesley Streets, building works, services, architectural finishes, utilities services diversions and connections. The location of the Aotea Station is primarily beneath the Albert Street, connecting the Contract 2 (C2) cut and cover tunnels to the north and the tunnel-boring-machine (TBM) tunnels to the south. The works are approximately 380m long by 18m wide and will be excavated around 18-20m below ground level. Additional boxes branch off from the tunnel alignment at Kingston Street (to form the Plenum), Victoria Street (for two entrance buildings to the Aotea Station) and Wellesley Street (to

Auckland Transport (AT) has obtained a resource consent for an Over Station Development (OSD) on the Bledisloe Car Park site (Council Reference R/LUC/2016/2647). The proposal involves the construction of a 24-level building comprising offices, retail and food and beverage tenancies, and public features including a plaza and a through site link. The proposed OSD is not part of the Link Alliance contract and will be progressed separately by AT.

Construction Noise and Vibration Delivery Work Plan Given the nature and scale of the Aotea Station construction, works will be undertaken in a staged manner, involving: ·
·
·
Five stages of early works (canopy removal, network utility relocation and site establishment work), being undertaken from October 2019 to March 2020 (Stages 1 to 3) and December 2019 through to August 2020 (Stages 4 and 5); these works have been authorised by separate Outline Plans (Council ref. OPW60345651 and OPW60348747); Main construction works (the ‘Aotea main works’) involving construction of the station box, associated above ground structures, mined tunnels for the rail tracks, internal finishing’s, structural fitout, all Mechanical, Electrical, Fire and Hydraulic (MEFH) installation, and architectural finishing’s2. The Aotea main works will be undertaken from early-2020 through to late-2023; and Ground reinstatements (from late-2022) and urban realm improvements. These works will be described in a future Outline Plan2.
Refer to Section 2 of the Construction Environmental Management Plan (CEMP) for a detailed description of the Aotea main works.
1.2 CNV DWP Staging To reflect the staged construction approach for Aotea Station, CNV DWPs will be developed in stages. This CNV DWP addresses the Aotea Station main works, which are detailed in the Project Construction Environmental Management Plan and summarised in Section 2 of this DWP. DWPs will also be prepared for the Bluestone Wall reconstruction on Albert Street and public realm reinstatement.
1.3 Purpose of the CNV DWP In accordance with CRL designation Condition 36, the purpose of this CNV DWP is to identify and provide for implementation of the Best Practicable Option (BPO) to avoid, remedy or mitigate adverse noise and vibration effects resulting from construction during the Aotea Station main works. It identifies the noise and vibration performance standards that must, where practicable, be complied with and details the management and control methodologies to be implemented in order to achieve compliance. Where compliance cannot be achieved, the CNV DWP identifies BPO mitigation measures to be implemented on a site specific basis. This CNV DWP will be implemented throughout the entire construction period and will be the primary tool for the management of construction noise and vibration effects resulting from the Aotea Station main works. It is a ‘living document’ which may be updated as the project progresses and working conditions become clearer. If for example, construction method changes mean that the noise and vibration effects at an affected property are either reduced or maintained at the same level as a result of implementing the mitigation measures described in this CNV DWP, it is not 2
It is noted the architectural finishing component of works (the exterior look and feel of the Aotea Station) will occur during Phase 5 of the Aotea main works (approx. 2022 – December 2023). These finishings are still being designed and determined. Once designs are completed a separate Outline Plan and suite of DWP’s will be prepared, describing the finishings and other urban realm reinstatements, including ground reinstatement. That Outline Plan package will address the relevant Urban Design related Designation conditions (Condition 47 – 54).

Construction Noise and Vibration Delivery Work Plan intended to re-submit the CNV DWP to Auckland Council for re-approval (the DWP review process is set out in Section 1.6 below). This CNV DWP has been developed to enable consultation with and feedback from the Aotea Community and Business Liaison Group (CLG); and has been reviewed by Independent Peer Reviewer (IPR) prior to submission to Auckland Council (as per designation conditions 7 and 11, and condition 19 of the resource consent conditions). A record of consultation outcomes (CLG and IPR) is included in Appendix I. This CNV DWP forms part of the CEMP for the Project.

Each phase of works involves multiple construction activities which will be undertaken throughout the Aotea Project site in phases. The phases associated with the Aotea main works involve; · · ·
Foundation works to form the perimeter walls of the station box and underground running tunnels. This involves diaphragm wall construction, roof construction, piling and jet grouting; Construction of the Aotea Station platforms, Main Station Structure, concourse, entrance structures and Plenum, and; Structural fitout of the Aotea Station including MEFH installation, and internal and architectural finishing’s.
The works require the operation of a Construction Support Area (CSA) within the Bledisloe House car park site and a portion of Mayoral Drive. Equipment used to undertake these works will be predominantly situated in the CSA. Upon completion of the Aotea main works, the area will be repurposed in preparation for urban realm reinstatement works2. The methodology for the construction of the Aotea Station is predominantly based on a ‘top down’ and ‘bottom up’ approach. The ‘top down’ approach relates to the southern end of Albert Street (south of Durham Street) and involves the installation of the ‘roof structure’ early on, which enables a limited number of traffic lanes to operate concurrently with the construction of the station, which occurs beneath. This approach reduces the construction effects on traffic flow within the city centre. The tunnel alignment on the northern end of Albert Street (north of Durham Street) will be constructed using a ‘bottom up’ methodology. A detailed description of the Aotea main works is included in the CEMP and includes; · · ·
an overview of the works including indicative timeframes in Table 2-1. the construction sequencing including equipment and earthworks volumes for the works in Table 2-2. further detail of the CSA in Section 2.6.2 of the CEMP. Drawings indicating the staging of the construction activities and proposed layout of the CSA is provided as Appendix B.
It is noted that the Bluestone Wall reconstruction works (Condition 45 of Designation 2500-1), public realm reinstatement works and details of architectural finishing’s for the Aotea Station (Condition 47 – 54 of Designation 2500-1), will form part of separate Outline Plan packages to be prepared in the future prior to the commencement of the respective works2.
2.2 Programme The Aotea main works are anticipated to take approximately 45 months to complete, occurring from April 2020 to December 2023 (approximately) as detailed in Table 2-1 in Section 2.2 of the CEMP. Some construction activities outlined in each phase of the Aotea main works will occur in parallel.
2.3 Hours of Operation Construction works will generally be undertaken between 7am and 10pm Monday to Saturday. Page 15
| Aotea Station Main Works
Construction Noise and Vibration Delivery Work Plan Designation Condition 36.3(b) requires piling and road cutting to be restricted to between the hours of 7am to 7pm, Monday to Saturday. Concrete pouring associated with the roof structure for the station may be undertaken during evenings and night times.

4. Equipment Noise and Vibration Source Data 4.1 Noise Sources Various construction activities and pieces of equipment will act as noise sources on site. Table 5 details predicted noise levels from the likely significant noise sources at various receiver setback distances. The noise data has been taken from British Standard 5228-1:2009 “Code of practice for noise and vibration control on construction and open sites�, manufacturers data or the AECOM database of noise measurements. The noise levels do not account for mitigation. The noise levels detailed in Table 5 are placeholders, and actual equipment noise levels and model numbers will be recorded and updated within the table when work commences. Updates will be provided as an appendix to this CNV DWP. The noise levels detailed in Table 5 allow identification of the need for mitigation or management to achieve compliance with the Project noise criteria. Section 6 of this CNV DWP provides details of management procedures and mitigation measures. A summary of equipment used for each stage of works has been provided in Appendix J.

Construction Noise and Vibration Delivery Work Plan
6. General Management Procedures and Mitigation Measures The proposed works have the potential to exceed the relevant construction noise and vibration limits at the closest receivers. To avoid/minimise exceedances it is vital that appropriate mitigation methods and measures are utilised. This DWP identifies the methods to achieve best practicable option for mitigating adverse effects during the construction works. These methods and measures will include, but not be limited to, those detailed in this section of the CNV DWP.
6.1 Training Procedures relating to environmental training, including noise and vibration site management procedures are detailed within the CEMP for the Aotea main works. As a minimum before commencing work on site all personnel will receive training based on this CNV DWP and relevant to their scope of works. If required, specific training will be provided for site personnel. Training will cover: ·
Roles and responsibilities for managing noise and vibration.
·
Familiarisation with noise and vibration limits.
·
Details of noise and vibration sources on-site.
·
Noise and vibration mitigation and management procedures.
·
Location of sensitive and notable receivers.
·
Construction noise and vibration effects on receivers.
·
Details of any operational requirements and constraints identified through communication and consultation.
·
Complaints management procedures.
6.2 Construction Vehicles, Traffic and Deliveries Noise mitigation methods and measures for construction vehicles, traffic and deliveries shall include, where practicable
Page 23
·
Fitting engine exhausts with silencers.
·
Using broadband reversing alarms.
·
Minimising slamming doors.
·
Minimising speed and engine revs.
·
Controlling / limiting noise from vehicle stereos being operated on site.
·
Minimising the use of horns.
·
Turning engines off when stationary for extended periods of time.
·
Placing bedding layer or resilient liner in truck trays
·
Using rubber seals around tailgates.
·
Minimising track squeal from tracked equipment such as excavators, by maintaining tracks regularly. | Aotea Station Main Works
Construction Noise and Vibration Delivery Work Plan
6.3 Plant and Equipment Designation Condition 21.1 (m) requires that site offices and less noisy construction activities be located at the edge of the construction yards where practicable (refer to the CEMP for further detail on the layout of the Construction Support Areas). Plant and equipment noise and vibration mitigation methods and measures shall include, where practicable:
Page 24
·
Selecting plant and equipment with low noise and vibration emission levels.
·
Turning off plant and equipment or throttle them down to a minimum when not in use.
·
Selecting appropriately sized equipment for the task.
·
Electric motors could be used as a substitute for diesel engines where practicable.
·
Using mufflers and engine covers/screens where appropriate.
·
Ensuring equipment is operated in the correct manner and correctly maintained, including replacement of engine covers, repair of defective silencing equipment, tightening of rattling components, repair of leakages in compressed air lines and shutting down of equipment not in use.
·
Avoiding, where practicable, the night-time use of equipment which generates impulsive noise, including: o
impact piling
o
dropping materials from a height
o
metal-to-metal contact on equipment.
·
Minimising drop height of materials when transferring (e.g. loading and unloading vehicles and storage areas).
·
Enclosing generators with an effective muffler.
·
Using power from Vector Electricity Network rather than from generators.
·
Reducing noise and vibration emissions from plant that has the potential to exceed the criteria by installing silencers, vibration isolation or other appropriate mitigation.
·
Maximising the distance between the engine exhausts of fixed plant and the nearest sensitive building façade.
·
Placing tools and equipment on the ground, rather than dropping.
·
Covering surfaces with resilient material where tools / equipment are placed.
·
Not dragging equipment on the ground.
·
Minimising the need for striking bare metal with tools.
·
Where spoil is being loaded into a dump truck, or fill materials are being unloaded from a dump truck, position the truck to minimise tracking movements.
·
Managing noise generated from the use of concrete, including by limiting noise generated by aggregate loading or by hammering the mixing.
·
Using broadband reversing alarms on all mobile equipment. | Aotea Station Main Works
Construction Noise and Vibration Delivery Work Plan ·
Crane and secure loads using straps rather than chains where safe and practicable.
·
Locate plant and equipment away from sensitive areas, such as next to residential buildings, to maximise distance from affected parties. Where this is not possible restricted hours of operation should be considered.
6.4 Pneumatic Breakers Noise and vibration mitigation methods and measures for breaking activities shall include, where practicable: ·
Selecting equipment for the job that takes into account the need to minimise the length of time taken to complete the operation and minimise noise generation.
·
Not “blank” firing the hammer. The activating valve should only be operated with the hammer in contact with the surface to be broken.
·
Keeping breaker bushes and shafts greased as necessary.
·
Using the correct chisel / tip shape for the type of material being broken.
·
Using acoustic screens which block line of sight between breaker and sensitive receivers where work is contained within a compact area.
6.5 Piling and Compaction Noise and vibration mitigation methods and measures for piling and compaction activities shall include, where practicable: ·
Minimising cable slap and chain clink.
·
Providing mufflers and engine covers/screens on plant where appropriate.
·
Removing obstructions which may exacerbate vibration transmission where appropriate, prior to piling operations.
·
Minimise alternating rotation of the bored piling auger to loosen spoil into the muck bin. Shaking the ‘kelly bit’ connection creates a very loud banging that can result in noise complaints.
6.6 Noise Barriers and Enclosures Noise barriers or enclosures will be used in areas where the noise limits are predicted to be exceeded, and where they provide effective mitigation. Noise barriers will generally only be effective for ground floor receivers where noise levels would be reduced by approximately 10 dBA. For a noise barrier to be effective it must physically obstruct line of sight between the noise source and receiver. Receivers on the first floor and above will be able to see over the noise barrier and it will provide little attenuation. An effective noise barrier is constructed as follows:
Page 25
·
Positioned to physically obstruct line of sight between the construction work and receiver, where this is practicable.
·
Positioned as close as practicable to the noisy construction activity. | Aotea Station Main Works
Construction Noise and Vibration Delivery Work Plan ·
Abutted or overlapped to provide a continuous screen with no gaps at the base or between panels.
·
Be a minimum of 2.4m high.
Noise barriers may be constructed from plywood with a minimum surface mass of 10kg/m2. Proprietary products such as Flex Shield are available that have a lower surface mass but provide the same or better levels of noise attenuation. Flex Shield barriers shall be utilised during utilities relocation and piling due to the temporary/ mobile nature of these works. A mobile noise barrier with a minimum height of 3m will be positioned inside the permanent 2.4m noise barrier during noisy activities outside sensitive receivers. Activities that require a barrier with height greater than 2.4m are identified in the relevant SSCNMP’s. Noise enclosures should be utilised where practicable as they provide better attenuation to receivers above ground floor level. Where enclosures are proposed their design will be agreed with the Project Acoustics Specialist.
6.7 Traffic tyre noise Vehicle movements may cause temporary decks, steel plates and manholes to rock or move, giving rise to nuisance noises. Sharp changes in the level of the road surface may result in tyre noise. Link Alliance will use the following methods to reduce noise from these sources so far as reasonably practicable, especially where the noise source will exist for long periods: ·
Firmly fix traffic decks to the road or other structural elements to prevent motion.
·
Placing rubber beneath traffic decks and steel road plates where movement occurs.
·
Providing smooth transitions between changes in road surface level.
·
Ensuring manhole covers are fitted correctly.
6.8 Scheduling of Activities Scheduling of construction activities can be a key tool for managing construction noise and vibration effects. The time of day and the duration of the construction activities will be adjusted after consultation, where possible, to avoid particularly sensitive times for affected receivers. Consideration will also be given to respite periods and avoidance of activity on certain days (if requested by affected neighbours), where practicable. Night time disturbance to nearby residential receivers will be reduced by carrying out noisy activities during the day.

Construction Noise and Vibration Delivery Work Plan
7. Communication 7.1 Communication Good stakeholder communication practices are a key component for the management of noise disruption from construction activities. Prior to construction commencing, clear communication channels will be established between the project team and those in the community potentially most affected by construction activities. It is important that information is provided in a transparent and consistent manner in relation to exposure, duration, mitigation and management measures. Designation Condition 36.3(g) requires a record to be kept of communication and consultation with sensitive receivers with regard to construction noise and vibration impacts. Designation Condition 16.1 requires that communication and consultation is undertaken, as soon as reasonably practicable (and at least once following confirmation of construction timing and methodology), with any Notable Noise and Vibration Receivers located within 100 metres of the designation footprint. A record of consultations is provided in Appendix E of this CNV DWP. The record includes details of when the communication/ consultation occurred, what the comments were from the sensitive receivers, where the comments have been incorporated into the CNV DWP. On-going communication and consultation will be undertaken with notable noise and vibration receivers throughout the duration of construction occurring in the vicinity. This communication will be reported back to the “key contacts” (see designation Condition 13) and the Auckland Council Compliance Monitoring officer for their review and confirmation of any further action to be undertaken. The Aotea Station Stakeholder and Communication Manager has a key responsibility to keep the community informed of construction activities. The following methodology sets out expectations for stakeholder communication with regards to noise and vibration generated by the construction works, with further detail provided in the Communication and Consultation Plan:
Page 27
·
A contact person will always be available during works, and the project contact details will be prominently displayed at the entrance to the site(s) so that they are clearly visible to the public.
·
Individual notification shall be provided and meetings offered to all neighbours that are predicted to experience noise or vibration levels that exceed the limits detailed in Section 3 of the CNV DWP after the BPO mitigation as detailed in Section 6 has been applied. Where it is impractical to avoid an exceedance, communication and consultation shall be undertaken with the receiver to identify methods and measures to mitigate the adverse effects of construction, including identifying why the selected management and mitigation measures and methods reflect the best practicable option.
·
Written notification to raise awareness of the works, the required construction activities and their duration should be provided at least 20 working days prior to the commencement of the works.
·
The Aotea Station Stakeholder and Communication Manager will make contact with the affected and notable receivers identified in Table 7 and Table 8 to engage in a consultative
| Aotea Station Main Works
Construction Noise and Vibration Delivery Work Plan process prior to construction. This may involve a face to face meeting or be carried out over the phone as suits the needs of the receiver. The Link Alliance will provide the affected and notable receivers identified in Table 7 and Table 8 with the following information: -
An overview of the works proposed, including duration, activities to be undertaken, potential impacts etc.;
-
The site and facilities layout;
-
Dates for key milestones (road closures, site establishments and disestablishment etc.); and
-
Project contact details for general queries or complaints.
Where changes are made to any of the above items, in particular to hours of operation or to likely duration of the operation, the affected and notable receivers identified in Table 7 and Table 8 will be notified. ·
As required, ongoing engagement throughout the works with Notable Noise and Vibration receivers and any other neighbours raising concerns.
·
Regular notifications (at least monthly) will be provided to affected receivers with an update on the progress of the works, and the specific activities (including locations) due to be undertaken next.
·
A record will be kept of all communications in Appendix E of this CNV DWP.
·
All concerns and complaints regarding construction noise and vibration will be dealt with in accordance with Section 7.2 of this CNV DWP.
7.2 Complaints Procedure Procedures relating to environmental complaints are detailed within Section 7 of the Communication and Consultation Plan. All complaints will be addressed in accordance with these procedures and a record maintained in a Project Complaints Register. Complaints will be dealt with in a responsible manner to ensure a relationship of trust and reliability between the community, the Link Alliance and CRLL is developed. The project will be contactable 24/7 through the Freephone number. Link Alliance shall ensure that: · ·
·
The Link Alliance Communications and Engagement Team handles all complaints that arise on the project. The community is notified of the project contact details through which complaints can be made. This will include the website, works notifications, onsite signage and project publications and newsletters. Link Alliance staff shall be briefed on the complaints process and are prepared to receive complaints through the Freephone number, by email, in writing or through face to face contact.
The process for managing complaints is set out in Table 9. Page 28

Description All complaints are forwarded to the Link Alliance Aotea Communications & Engagement Team. The Aotea Communications and Engagement Team acknowledges the complaint on day of receipt by phone or in writing. If the Communications Engagement Team is not available, the Link Alliance Aotea Station Project Manager or another member of the project team shall acknowledge the complaint. The contact details and details of the complaint are entered into the CRM database. Acknowledgement of a complaint is provided on day of receipt. Response timeframes are listed in Section 7 of the Communication and Consultation Plan. The Link Alliance Aotea Communications and Engagement Team shall work closely with the Link Alliance Aotea Station Project Manager or Construction Manager to resolve complaints. They are proactive in keeping complainants informed of what action is being taken to address their concerns. If a complaint cannot be resolved within the complaints process timeframe, the complainant is invited to a meeting with the Link Alliance Communications and Engagement Manager and the Aotea Station Project Manager (or their delegated nominees). Resolution timeframes should be agreed at this meeting. All meetings shall be recorded in the CRM database to ensure that a complete record of times, dates and location of meetings is maintained. When a complaint is resolved it shall be ‘closed out’ as an action in the CRM. Each month a record of complaints activity will be reviewed by the Link Alliance Aotea Community Manager to check that all actions have been closed out. Complaints data is reviewed regularly by the Link Alliance Communications and Engagement Manager.
7.2.1. Auckland Council Reporting In accordance with the designation and resource consent conditions, a record of complaints shall be maintained on-site and be available to the Auckland Council Compliance Monitoring Office on Request (refer Section 5.2 of the Communication and Consultation Plan). The record shall be provided to Auckland Council every two months (or as otherwise agreed) and to the “key contacts” listed in the CEMP. Where a complaint remains unresolved or a dispute arises, the Link Alliance shall provide the Auckland Council Compliance Monitoring Officer with all records of the complaint and how it has been dealt with and addressed and whether the Requiring Authority considers that any other steps to resolve the complaint are required.

8. Monitoring 8.1 Noise Construction noise will be measured and assessed in accordance with the requirements of New Zealand Standard NZS 6803: 1999 “Acoustics - Construction Noise” Noise monitoring will be conducted by the Acoustic Specialist or trained noise monitoring staff as identified in Table 2 of this CNV DWP. The equipment noise levels detailed in Table 5 are placeholders. All equipment that is predicted to exceed 75 dB LAeq at 5m will be measured, where practicable, when first operating on site. Actual equipment noise levels at 5m and equipment model numbers will be recorded. Construction monitoring shall be undertaken during phases of construction when noise has potential to exceed the limits or in response to reasonable noise complaints. Noise monitoring shall also be undertaken if the construction methodology changes, such that noise criteria may be exceeded at other locations. The SSCNVMPs identify monitoring locations and the timing of monitoring at the most affected receivers. In addition to the monitoring identified in the SSCNVMPs, noise monitoring will be carried out at positions representative of noise sensitive locations at appropriate periods to check ongoing compliance with the construction noise limits. The monitoring position will be at ground floor level. Noise will be measured 1m from the most affected façade of the building, or in the area which relates to a noise complaint. If it is not practicable to measure at this position, measurements will be taken at a representative location and adjusted for distance and façade reflections if necessary. Measurements will also be taken at a known distance, such as 5m, from the noise generating equipment to establish source noise levels. Additional measurement positions may be necessary if the initial measurement results indicate that noise may exceed criteria at other areas of the building façade. These measurements will be undertaken 1m from the façade if windows are normally open or inside the building if windows are normally closed. Where internal measurements are required it will be necessary to control noise from local sources, such as people using the telephone, to ensure only construction noise is measured. Noise monitoring will be conducted for 10-15 minutes at each measurement position, during representative construction activity. The noise level will be reported with the measurement duration (e.g. 65 dB LAeq (15min))

8.2 Vibration Construction vibration levels will be measured and assessed in accordance with the requirements of German Standard DIN 4150-3:1999 “Structural vibration – Part 3: Effects of vibration on structures”. Vibration monitoring shall be undertaken during phases of construction when vibration has potential to exceed the limits or in response to reasonable noise complaints. Vibration monitoring shall also be undertaken at identified SSCNVMP locations and if the construction methodology changes, such that vibration criteria may be exceeded at other locations. Vibration monitoring shall only be undertaken by the Acoustic Specialist or trained vibration monitoring staff as identified in Table 2 of this CNV DWP. Vibration shall initially be measured at the closest building foundations (usually at basement or ground floor level), and this requires consent to access the building of interest. Additional measurement positions may be necessary if the initial measurement results indicate that vibration may exceed criteria within other areas of the building. It may also be necessary to measure vibration levels in the habitable areas of buildings in response to a complaint. Vibration monitoring will be conducted during representative construction activities and comprise measurements of peak particle velocity (PPV) at one second intervals. The duration of the vibration measurements will be sufficient to capture the highest vibration level from the source. The vibration monitoring equipment (geophones) will be fixed to building structural members (e.g. with clamps, cable ties, or weighed down with sandbags). The geophones will ideally be located at or near the façade of the building facing the vibration source and will be located away from areas where extraneous vibration (e.g. from footfall or building services) could affect the results. Vibration monitoring shall also be undertaken in response to reasonable vibration complaints, or if the construction methodology changes such that vibration criteria may be exceeded at other locations. Figure 4 outlines the process to be followed when monitoring vibration. Note that matters relating to building condition survey and response to damage are set out in Sections 8.4 and 9.3.

Construction Noise and Vibration Delivery Work Plan
8.3 Reporting All noise and vibration monitoring shall be summarised in a report and submitted to the Aotea Station Stakeholder and Communication Manager and the Environmental and Sustainability Manager (ESM) within one week of the assessment. The reports shall be kept at the site office and made available to Auckland Council upon request. A noise monitoring template is presented in Appendix G. A vibration monitoring template is presented in Appendix H.
8.4 Building Condition Surveys A pre-construction building condition survey will be undertaken at all of the identified buildings detailed in Table 8 before construction begins on the Project. Designation Condition 46 describes the process for building condition surveys. The building condition surveys will generally be undertaken as follows: 路
The building surveys will be undertaken by an independent senior qualified person
路
The survey shall include: o
Any information about the type of foundations
o
Existing levels of damage (aesthetic, superficial, affecting levels of serviceability)
o
Whether observed damage is associated with structural damage
o
Susceptibility of building or structure to further movement
o
Photographic evidence
路
The Link Alliance will provide the building condition survey structure survey report to the property owner and the Council within 15 working days of the survey being undertaken
路
The Link Alliance shall carry out visual inspections of the surrounding ground and external building facades of the listed buildings adjacent to any trench works to monitor any deterioration or movement of any pre-existing cracks
The buildings may require further surveys during construction if complaints are made or if the vibration criteria have been exceeded. A post-construction condition survey of the same buildings will be conducted after the conclusion of works in the area that have the potential to generate vibration at levels approaching or exceeding the limits in Condition 33. A report will then be prepared. Where a post-construction building condition, survey confirms that the building has deteriorated as the result of construction the damage will be rectified.

9. Contingency Measures This section describes contingency measures to be implemented in the event that the noise and/or vibration limits specified within this CNV DWP and/or in an approved SSCNVMP are exceeded. The Aotea Station Stakeholder and Communication Manager will liaise with affected receiver (refer Table 2 of this CNV DWP) throughout the following processes.
9.1 Management Process Where any construction activity is predicted and/or measured to exceed the construction noise or vibration limits the following process will be applied: ·
Check that the BPO and all relevant management measures have been implemented.
·
The Aotea Station Stakeholder and Communication Manager will engage with all affected parties, to understand their particular sensitivities, including times, activities and locations. The Aotea Station Stakeholder and Communication Manager or nominated representative shall be available 24/7 during the proposed works.
·
Carry out noise and/or vibration monitoring of the construction activity to verify the extent of any adverse effects.
·
Implement further mitigation and/or contingency measures to avoid significant adverse effects as practicable and agreed with the affected party (refer Sections 9.2 to 9.5 of this CNV DWP).
9.2 Noise If noise monitoring demonstrates non-compliance with the noise limits identified in the approved SSCNVMP, the following procedures shall be implemented:
Page 35
·
Undertake additional noise measurements, as necessary, to determine the extent of the exceedance.
·
Discuss additional mitigation options with the Aotea Station Project Manager as soon as the extent of the exceedance has been determined. This may include immediately stopping works.
·
Undertake noise measurements once recommended mitigation measures have been implemented to confirm that the mitigation has been effective, and the noise limits are now being met for the periods agreed.
·
Preparation of a report recording the findings of the survey and detailing additional mitigation or management options. Copies of the report will be provided to CRLL, the Station Project Manager, Aotea Station Communication and Consultation Manager and the Environmental and Sustainability Manager.
| Aotea Station Main Works
Construction Noise and Vibration Delivery Work Plan
9.3 Vibration – Building Damage If vibration monitoring demonstrates non-compliance with the vibration building damage limits identified in the approved SSCNVMP, the construction activity responsible for the exceedance shall cease as soon as it is safe and practicable to do so. A detailed building condition survey shall then be undertaken by a suitably qualified engineer to determine if any damage has occurred. The survey shall include, but not be limited to, the following: ·
Comparison of existing condition of building including existing levels of any aesthetic damage or structural damage against pre-construction building survey.
·
Recording (including photographs) the major features of the buildings including location, type, construction, age and present condition, including defects (cracks).
·
Preparation of a report recording the findings of the survey. A copy of the report will be given to the building owner and another copy will be kept at the site office.
If damage has not occurred, then that activity can continue provided the measured vibration level is not exceeded further. If minor damage has occurred, such as cosmetic cracks, additional mitigation should be provided, including consultation with a structural engineer to confirm that no further damage will occur, as per Condition 38.4. Following this, activity can continue following this provided the measured vibration level is not exceeded further. If moderate or severe damage has occurred and the best practicable option has been implemented, it will be necessary to stop work, if safe to do so, and investigate alternative construction methods. All damage due to construction activities will be repaired within a reasonable timeframe after the construction phase ceases.
9.4 Vibration – Amenity If a complaint is made by a building occupant with regard to vibration levels, vibration monitoring will be conducted in the relevant rooms of the building. If the limits are found to be exceeded, then a SSCVMP will be prepared for that receiver.
9.5 Additional measures Where noise and vibration impacts are unavoidable and significant after all reasonable and practicable measures are implemented, alternative mitigation measures, such as temporary relocation or the provision of architectural treatments, will be considered. Temporary relocation involves the relocation of affected occupants for short periods of time where all reasonable and practicable measures and respite periods are implemented, and further mitigation is impractical. Architectural treatments may also be sought and involve the provision of alternative ventilation where windows are to remain closed in order to further mitigate noise effects.

The Media Design School occupies floor 5 and floors 14-20, with other internal spaces vacant as the building is due a significant renovation in 2020/21. The school operates between 07:00 and 21:00 Monday to Thursday, between 07:00 and 18:00 on Friday and between 10:00 and 17:00 on Saturdays. Noise is a concern in many internal learning spaces. A lecture theatre is located on Level 5, with a glazed façade onto Albert Street. There is the potential for annoyance and disturbance to students and staff during learning sessions within the building on the Albert Street façade. The Media Design school plans to vacate the building in the second half of 2020 to move to new premises elsewhere in Auckland. The building is mechanically ventilated throughout, and internal spaces are typically 90% single glazed.
Concerns about noise and vibration for the tenants. Current construction has already caused annoyance Would like better communication and reliability of work timings
A 2.4m high noise barrier will be constructed around the Aotea construction areas for the duration of the main works. With the mitigation and management measures detailed in Section 6 of the CNV DWP and Table 3 of the relevant SSCNVMP, noise may be audible inside the building during the diaphragm wall, piling, bottom-up and roof construction works. Noise from excavators, piling, plate compactors and concrete breaking is likely to be audible during the different construction phases but will be intermittent in nature.

Site Specific Construction Noise and Vibration Management Plan – Bottom up construction
1. Introduction This is a Site-Specific Construction Noise and Vibration Management Plan (SSCNVMP) and forms part of the Construction Noise and Vibration Delivery Work Plan (CNV DWP) for the Aotea Station Main Works (the ‘Project’). This SSCNVMP provides a specific assessment of construction noise and vibration from the bottom up excavation works within the project designation. This SSCNVMP should be read in conjunction with the CRL Contracts 3 Aotea Station Main Works Construction Noise and Vibration Delivery Work Plan (CNV DWP) to which this document forms Appendix F, as it contains further details of the project, noise criteria, monitoring and general mitigation measures. An overview of the works and details of the construction methodology are contained in Section 2.0 of the CNV DWP.
1.1 Objective The objective of this SSCNVMP is to detail the best practicable option to avoid, remedy or mitigate adverse effects on sensitive receivers resulting from construction noise and vibration that does not comply with the Project Standards defined in Section 3.0 of the CNV DWP.
1.2 Site Plan The locations of the bottom up construction works are shown in Figure 1.

Details of the construction equipment that is likely to be used in the above activities and the associated noise levels can be found in Section 4.1 of the CNV DWP. Details of the equipment that is expected to generate high levels of vibration can be found in Section 4.2 of the CNV DWP. The equipment levels detailed are placeholders. All equipment will be measured operating independently and then actual equipment noise/vibration levels and model numbers will be recorded and updated within the table.

Site Specific Construction Noise and Vibration Management Plan – Bottom up construction
4. Façade performance and internal noise levels 4.1 Noise The bottom up construction works are located so close to a number of receivers that internal noise levels will be high. Use of the mobile cranes and tower crane has the potential to exceed the Project noise criteria. With mitigation and management measures implemented and barriers installed, the noise levels at the most exposed façade of a number of properties will still exceed the noise criteria by more than 5dB during some construction activities. These properties are detailed in Table 3 along with an estimate of the current façade performance and the worst-case internal noise levels during bottom up construction works.

1. Introduction This is a Site-Specific Construction Noise and Vibration Management Plan (SSCNVMP) and forms part of the Construction Noise and Vibration Delivery Work Plan (CNV DWP) for the Aotea Station Main works (the ‘Project’). This SSCNVMP provides a specific assessment of construction noise and vibration from Diaphragm wall Construction works within the project designation. Diaphragm walls (D-Wall) will be constructed adjacent to the building alignment, providing the structural perimeter of the station box. The D-walls will provide earth retaining and support for the tunnel roof structure. D-walls will be constructed from the southern end of the Aotea Station to Victoria Street. This SSCNVMP should be read in conjunction with the Aotea Station Main Works Construction Noise and Vibration Delivery Work Plan (CNV DWP) to which this document forms Appendix F, as it contains further details of the project, noise criteria, monitoring and general mitigation measures. An overview of the works and details of the construction methodology are contained in Section 2 of the CNV DWP
1.1 Objective The objective of this SSCNVMP is to detail the best practicable option to avoid, remedy or mitigate adverse effects on sensitive receivers resulting from construction noise and vibration that does not comply with the Project Standards defined in Section 3 of the CNV DWP.
1.2 Site Plan The locations of the diaphragm wall works are shown in Figure 1.

3. Activities Construction activities for D-wall construction along with approximate duration of works and hours of operation are shown in Table 2. Table 2 Proposed works Stage D-Wall
Details of Works
Equipment utilized
· Install precise guide wall (the guide wall will serve as a trench for collecting bentonite slurry ejected during concreting works). · Excavation of D-wall in sections of approximately 2-3m width using a Hydro fraise rig HC05®. · Support trench using bentonite slurry, which is injected into the trench to eliminate groundwater ingress into the excavation. · Spoil from trench is raised using reverse circulation of drilling fluid. · The first D-wall will be installed as the primary panel. A secondary panel will be cast between two primary panels to form a watertight structural and cut-off D-wall. · Construction of D-wall will be undertaken in this sequence, moving along the wall until complete. · Removal of trees outside Crowne Plaza:
· · · · · · · · · · ·
Concrete breaker Hydro fraise rig Crawler cranes Mobile cranes Excavator 6-wheeler truck Pumps Concrete trucks Delivery trucks Desanding plant Bentonite plant
Duration of Works and hours of operation 20 months (April 2020 to January 2022), 07:00 – 19:00 Monday to Saturday
Details of the construction equipment that is likely to be used in the above activities and the associated noise levels can be found in Section 4.1 of the CNV DWP. Details of the equipment that is expected to generate high levels of vibration can be found in Section 4.2 of the CNV DWP. The equipment levels detailed are placeholders. All equipment will be measured operating independently and then actual equipment noise/vibration levels and model numbers will be recorded and updated within the table.

4. Faรงade performance and internal noise levels 4.1 Noise The diaphragm wall (D-wall) works are located so close to a number of receivers that internal noise levels will be high. Use of the D-wall (hydro fraise) rig, Bentonite plant, concrete breakers and concrete saw have the potential to exceed the Project noise criteria. An enclosure is unlikely to be practical in a number of locations due to space restrictions on site. It is recommended that the suitable use of enclosures is determined at each location once details regarding the equipment and size of working area are available. An enclosure will form the best practicable option for noise mitigation if it is able to be installed safely around working equipment. Screening is to be provided to the ground floor of affected receivers by noise barriers around all noisy construction works. With the above mitigation and management measures implemented and barriers installed, the noise levels at the most exposed faรงade of a number of properties will still exceed the noise criteria by more than 5dB during some construction activities. These properties are detailed in Table 3 along with an estimate of the current faรงade performance and the worst-case internal noise levels during diaphragm wall construction works.

Site Specific Construction Noise and Vibration Management Plan - Piling
1. Introduction This is a Site-Specific Construction Noise and Vibration Management Plan (SSCNVMP) and forms part of the Construction Noise and Vibration Delivery Work Plan (CNV DWP) for the Aotea Station main works (the ‘Project’). This SSCNVMP provides a specific assessment of construction noise and vibration from piling works within the project designation. Works include installation of steel-reinforced concrete piles to rock level/refusal, via bored piling, in the northern section of the Aotea Station up to the interface with the C2 contract works. This SSCNVMP should be read in conjunction with the Aotea Station Main Works Construction Noise and Vibration Delivery Work Plan (CNV DWP) to which this document forms Appendix F, as it contains further details of the project, noise criteria, monitoring and general mitigation measures. An overview of the works and details of the construction methodology are contained in Section 2.0 of the CNV DWP
1.1 Objective The objective of this SSCNVMP is to detail the best practicable option to avoid, remedy or mitigate adverse effects on sensitive receivers resulting from construction noise and vibration that does not comply with the Project Standards defined in Section 3.0 of the CNV DWP.
1.2 Site Plan The locations of the piling works are shown in Figure 1.

4. Faรงade performance and internal noise levels 4.1 Noise The piling works are located so close to a number of receivers that internal noise levels will be high. Use of the piling rig, excavators, and vibro-hammer has the potential to exceed the Project noise criteria. With the mitigation and management measures implemented and barriers installed, the noise levels at the most exposed faรงade of a number of properties will still exceed the noise criteria by more than 5dB during some construction activities. These properties are detailed in Table 3 along with an estimate of the current faรงade performance and the worst-case internal noise levels during piling works.

Site Specific Construction Noise and Vibration Management Plan – Roof construction
1. Introduction This is a Site-Specific Construction Noise and Vibration Management Plan (SSCNVMP) and forms part of the Construction Noise and Vibration Delivery Work Plan (CNV DWP) for the Aotea Station Main Works (the ‘Project’). This SSCNVMP provides a specific assessment of construction noise and vibration from Roof Construction works within the project designation. Roof Construction includes pouring of the roof slab in 10m sections, leaving approximately 5x8m holes to allow extraction and loading during further station works below ground. This SSCNVMP should be read in conjunction with the Aotea Station Main Works Construction Noise and Vibration Delivery Work Plan (CNV DWP) to which this document forms Appendix F, as it contains further details of the project, noise criteria, monitoring and general mitigation measures. An overview of the works and details of the construction methodology are contained in Section 2 of the CNV DWP.
1.1 Objective The objective of this SSCNVMP is to detail the best practicable option to avoid, remedy or mitigate adverse effects on sensitive receivers resulting from construction noise and vibration that does not comply with the Project Standards defined in Section 3 of the CNV DWP.
1.2 Site Plan The locations of the roof slab construction works are shown in Figure 1.

3. Activities Construction activities for roof slab works along with proposed start and end dates, and hours of operation, are shown in Table 2. Table 2 Proposed works Stage
Roof Slab Construction
Details of Works
Equipment utilised
· Install roof slab structure (slab will be cast in 10m sections with a capping beam across the width of the Station). · Roof slab will have holes (approximately 5x8m) to allow extraction of material and loading in of construction material for construction of the Station. · Reinstate the road after installation of the roof, leaving a number of openings. · Start mining and excavation to final depth occurs concurrently under the roof. · Concourse construction (install a gantry crane beneath roof structure to service both the concourse construction and platform construction). · Construct entrance building on the corner of Wellesley and Albert Street. · Construct internal walls, platform and overtrack exhaust (OTE) structure. · TBM breakthrough. · Finish structure on drive 1 retrieval area including lift shaft. · TBM will be retrieved from the first drive by a 450T crane. · TBM transported back to Mt Eden for second drive.
· · · · · · · ·
Excavator Concrete pumps 25T and 50T crane 6-wheeler trucks 45m radius tower crane TBM 450T crane Concrete trucks
Duration of Works (approximate) 41 months (April 2020 to September 2023)
Details of the construction equipment that is likely to be used in the above activities and the associated noise levels can be found in Section 4.1 of the CNV DWP. Details of the equipment that is expected to generate high levels of vibration can be found in Section 4.2 of the CNV DWP. The equipment levels detailed are placeholders. All equipment will be measured operating independently and then actual equipment noise/vibration levels and model numbers will be recorded and updated within the table. Concrete pouring of the roof slab is likely to occur during night time hours in order to expedite the construction of the roof slab and improve quality. Predictions of construction noise during night-time hours include only a concrete truck and concrete pump operational in the works area.

4. Façade performance and internal noise levels 4.1 Noise The roof slab construction works are located so close to a number of receivers that internal noise levels will be high during some activities. With the mitigation and management measures implemented and barriers installed, the noise levels at the most exposed façade of a number of properties will still exceed the noise criteria by more than 5dB during some construction activities. These properties are detailed in Table 3 along with an estimate of the current façade performance and the worst-case internal noise levels during roof slab construction works. Predicted noise levels for night works have been included in Table 3 where the building has a residential use or a commercial use that is operational during the night time period.

6.2 Vibration Monitoring Vibration monitoring will be carried out when works begin on site to determine actual equipment vibration levels and the attenuation provided by local ground conditions. If the initial vibration monitoring demonstrates that the emission radius for the plant is similar to that identified in the CNV DWP addendum, then the monitoring as detailed below will be carried out. If the initial monitoring demonstrates that vibration levels are lower than predicted fewer properties may require monitoring. Vibration monitoring will be carried out at the following receivers when the excavator is operating within 10 metres of the following buildings: Page 26

Comments In the fifth line of the first paragraph notes: “These noise levels are applicable 1m from any building façade”. We recommend changing the term “from any building façade” to “from the most exposed façade of a receiver” so that complies with NZS6803:1999 (per Condition 31.2)
Response Noted.
Table 6 Noise values presume free field conditions which are not going to exist at the Aotea Station works with so many surrounding buildings. We would suggest a more realistic distance propagation is presented and noted as such.
Noise values in Table 6 are free field but are placeholders. A 3D noise model has been generated for the project which considers other factors such as ground absorption and façade reflections. The 3D model has been used to assess noise levels against the criteria. Contour Maps in Appendix C and D shows the more realistic distance propagations.
Hydrovac levels are noted to be highly variable and quite noticeable due to their extended periods of operation. Selection of quiet equipment for this item is critical. (We note previous Aotea DWP used 107 vs 104 dB LAeq but expect the actual range is much higher) “The equipment noise levels detailed in Table 6 are placeholders” – Any changes to the noise counters expected from alterations to the DWP should be reviewed by Council’s SME Some activities in table 7 are considered long-term vibration as per DIN 4150 definition such as plate and roller compactors and vibro- driven sheet piles. The radii should reflect the lower criteria and may best be presented as either short term/long term for the relevant sources. Vibration contours should also be presented as “short term” and “long term” to reflect the varied criteria and impacts on structures “Table 7 summarizes the setback distance…inside of which exceedance of the building damage criteria…may occur at the foundation of receiving buildings”- This is only in reference to short-term vibrations. The setback distances for long-term vibrations should also be included. Table 7 “Concrete breaker” values correspond to hand-held equipment rather than n excavator mounted breaker which seems much more likely given the scale of the works. We recommend including the values for “Rock breaker (excavator with pick)” used in K Road CNV DWP document which are more realistic. Concrete/paver cutter should be included in the Management Procedures and Mitigation Measures. We recommend mobile barriers

Comments as used in Stages 4 and 5 of the Aotea Utility Relocation Works to provide some useful noise reduction to lower level receivers. The training provisions (6.1) could usefully reference 6.2-6.8 so all those trained fully understand the implementation of all requirements. E.g. Training should specifically cover the effective use of mitigation measures, not just the need for the mitigation measure. It is common to see temporary noise barriers poorly installed and thus ineffective presumably due to workers not understanding that the poor installation makes them weak. Additional mitigation should include:

Use of rubber tracks to eliminate squeal wherever possible is another form of recommended mitigation for tracked equipment. Grease tracks regularly (keep grease in cab): and if possible, use wheeled equipment. Additional mitigation should include: ·
Electric motors could be used as a substitute for diesel engines where practicable.
·
Diamond coring drills: Use thermic lance as an alternative.
· Saw cutting: Use hydraulic saw or wire cutter. Road Milling machines: Heat asphalt before milling. Additional mitigation could be the usage of only muffled breakers on-site. It may be informative for the prediction of rock breaking noise to be updated based on muffled breakers since these are readily available. We consider it appropriate to include the following as an additional mitigation measure (per Mt Eden proposal or similar). “Minimise alternating rotation of the bored piling auger to loosen spoil into the muck bin. Shaking the Kelly bit connection creates very loud banging that can result in noise complaints” With regards to enclosures, preliminary design details/examples/references should be

Response No.
“The monitoring position will be at the ground floor level” – This should not be the case as several buildings are expected to have highest noise levels at the façade at an elevated level due to height limitations of the noise barriers (e.g. overlooking balconies and openable windows at high level). The monitoring position should be where the receiver is most exposed to the noise from works, with monitoring equipment located at a position where there are relatively few obstructions to the noise source (e.g. balcony rails, glass, etc.)
Noted.

“Vibration monitoring shall only be undertaken by the Acoustic Specialist or trained vibration monitoring staff as identified in Table 3 of this CNV DWP” – Given the scale of these works and potential for disruption and complaints, should the monitoring personnel be independent from those in charge of advising on mitigation? “Vibration shall initially be measured at the closest building foundations (usually at basement or ground floor level) …” – This only applies to short-term vibration measurements. Longterm measurements measured at top level should be included as per DIN 4150-3:1999. In response to noise and vibration complaints, “reasonable” is an ambiguous term. This should be removed, or replaced with a clearer statement (e.g. “in response to any noise complaints unless they are clearly spurious”) Monitoring diagrams are difficult to follow due to cross overs and
No. Continuous noise and vibration loggers are being set up across the project in addition to the attended monitoring.

We do not consider “reasonable” to be an ambiguous term. This term has been used in all of the approved plans to date.

Remedial actions undertaken (if any) and the outcome of these, including monitoring of the activity. If a complaint is received about vibration amenity, and a measurement demonstrates exceedance of the CRL designation condition vibration limits, the following procedures will be implemented: · Further measurements may be required to determine the extent of the exceedance and identify the activity/activities responsible; · Review the mitigation strategy and construction methodology to ensure BPO is applied; Further measurements may be required to determine the effectiveness of BPO measures and reassess compliance status, etc. 8.1

Comments decision points not clearly labelled. Consider the use of the MDA style one (refer Mt Eden Early Works). “Where a post-construction building condition, survey confirms that the building has deteriorated as a result of the construction the damage will be rectified” – This is very brief and could be usefully expanded. We note Condition 36.3k(vii) requires the SSCNVMP to detail “Procedures for how works will be undertaken should they be required as a result of the building condition surveys;“
Response
Response No.
If the post construction survey confirms damage has occurred due to construction of the project the damage will be fixed. There is nothing more to say.
20
“If minor damage has occurred, such as cosmetic cracks, further mitigation will be applied if practicable. However, the activity can continue provided the measured vibration level is not exceeded further.” – Additional measures should be provided in this case prior to continuing works. As a minimum, confirmation that no further damage will occur from a structural engineer as per Condition 38.4 is required. Occupants will likely be alarmed at the sight of cracks, so appropriate action should be taken to ensure that the cracks do not worsen and the occupants are informed of such. We recommend continuous monitoring and live communication methodologies to confirm that no further damage will occur and occupants are not endangered despite the presence of visible damage to give peace of mind to the occupants.

Site Specific Vibration Management Plan Review The following comments apply to all SSCVMP’s where the properties listed appear in the relevant SSCVMP unless specifically noted otherwise. We note however that some properties are still to be assessed by AECOM or have been missed as mentioned in Table 2. General observations: 1. Condition 38.5 says SSCVMP’s will identify: “The methods and measures to mitigate vibration effects, including but not limited to, investigating alternative low-vibration construction methods, undertaking high-vibration works outside sensitive times, vibration barriers, building condition surveys, potential to offer temporary relocation of affected receivers, or other offers made by the Requiring Authority and agreed to by the affected receiver.” The SSCVMP’s presented here do not fully exhaust this list. We note the monitoring listed - while helpful to perceptions – is not going to reduce vibration itself. 2. There is no structural expert evidence presented that the proposed exceedances of the project criteria for any of the following SSCVMP’s are appropriate as mandated per condition 38.4. These need to be provided. Specific SSCVMP Comments Address

This is based on worst-case assumptions for ground type and vibration source characteristics. The purpose of vibration emission radii is to identify areas where management and monitoring of vibration levels may be required, as opposed to an accurate assessment of predicted vibration levels at receiver locations.

I3. Auckland Council Comments The CNVDWP and SSCNVMP has been subject to Auckland Council review, with comments being provided on 27 March 2020. The table below provides the Link Alliance response to Auckland Council comments.
Page 78
| Aotea Station Main Works
Construction Noise and Vibration Delivery Work Plan # Comment General 1 In our initial review we asked for details on the communication records and why these did not include all the receivers, such as Lollipops Auckland Central childcare center at 92 Albert Street. Why haven’t all the receivers been identified and when will this be completed? 2 A number of the SSCNVMP’s state that consultation will be undertaken in March 2020. Has this been completed yet? (date of this email is 27 March 2020) Façade reductions 3 IPR: Concerns raised that 35 dB LAeq requirement will not be met in bedrooms. Predicted noise levels are 35 – 40 dB LAeq in the SSCNVMP’s for: o 27-35 Victoria Street W, President Hotel. o 74 Victoria Street, Barclay Suits. o 75 Victoria Street, residential.
Response Further consultation with a number of properties will take place following the end of coronavirus lockdown.
Further consultation with a number of properties will take place prior to start of works. Text updated to state that the date for further consultation is TBC. Text added to the specific mitigation measures table within the Roof Construction SSCNMVP discussing the potential need to book rooms out if there is no practicable alternative. The CNV DWP (Section 9.5) lists additional measures if all other mitigation options are not practicable.
LA: < 40 dB in bedrooms with windows closed. Annoying and disturbing staff or guests. Possible sleep disturbance to guests in bedrooms facing Victoria Street. Potential for NZS 2107 internal noise level criteria (35-40 dB LAeq) for bedrooms to be exceeded during noisy activities. With the concrete pump placed as recommended internal noise levels are predicted to meet the criteria.
4
Auckland Council: Alternate mitigation may be necessary and should be addressed by LA. Or if the predicted noise levels do meet the criteria then the SSCNVMP’s need to be updated. IPR: There are a number of questions from IPR regarding the façade reduction being less than in the predicted noise levels due to poor door seals, such as at 53-63 Victoria Street West, Photo Store/café midnight/pawn shop. LA: The response from the LA is that they are comfortable with the predicted composite façade reduction detailed in the documents. Auckland Council: The predicted noise levels from concrete cutting are 75 – 80 dB LAeq which we agree are typical. The assumed sound reduction is 30 dB Rw from the windows and door. The IPR is concerned that this should be 25 dB Rw due to poor
Page 79

Where the IPR has raised concerns about door seals for individual receivers, these will be inspected by the Link Alliance and options for replacement/improvement explored with the building owner.
Construction Noise and Vibration Delivery Work Plan door seals. The difference in resulting noise levels inside are either 45 – 50 dB or 50 – 55 db. Both are acknowledged by LA are levels that will result in annoyance to staff and customers, or annoyance and loss of concentration. The mitigation remains 3m acoustic screening and the additional mitigation through consultation. Will consultation include consideration of improving door seals if this is a viable option for both parties? Internal noise levels 5 IPR: The noise levels expected within rooms are up to 60 dB LAeq. This is over the recommended internal limit of 35 dB LAeq in sleeping areas at night times. Examples are: · 98-102 Albert Street, Surf n Snow Backpackers · 103-107 Albert Street Manhattan Apartments LA: The response from the LA is that they are comfortable with the predicted composite façade reduction detailed in the documents. Auckland Council: The response from LA is very light on these matters. Internal noise levels of up to 60 dB LAeq in sleeping areas is a high level of noise. Significant concerns have been raised by the owners/occupiers. Communication records show that works to be scheduled outside of sleeping hours where practicable.
Works are to schedule outside of night-time hours where practicable. If it is not practicable to reschedule the works, equipment operating during night-time will only consist of the concrete truck and concrete pump, to be positioned at least 30 metres away from residential receivers. Note that the mitigation measure of locating the concrete pump and truck at least 30 metres away from the building is not included within the predicted noise level. The Link Alliance aims to provided 10 working day notification to impacted stakeholders/receivers prior to works commencing.
LA to provide more detail on night works and the predicted noise levels, effects to sleeping areas and mitigation. Are the predicted noise levels based on the concrete truck and pump placed at least 30 meters from the building when concrete pours occur during night-time hours?
6
Notice of noisy works is to be provided at LAeq in 24 hours – is this a long enough notification period for noisy night works for hotels, apartments and backpackers? IPR recommends that serious consideration needs be given to secondary glazing or relocation during night works. LA response is that additional mitigation may involve booking of the most affected rooms rather than installation of secondary glazing. Auckland Council: Either option will work, and the outcome will depend on further

To be confirmed following further consultation.
Construction Noise and Vibration Delivery Work Plan consultation with the owners of the apartments, hotels and backpackers. Please confirm. Construction vibration 7 IPR: Some activities in table 7 are considered long-term vibration as per DIN 4150 definition such as plate and roller compactors and vibro-driven sheet piles. The radii should reflect the lower criteria and may best be presented as either short term/long term for the relevant sources. Vibration contours should also be presented as “short term” and “long term” to reflect the varied criteria and impacts on structures We consider the radii presented to be appropriate for the various activities. “Table 7 summarizes the setback distance…inside of which exceedance of the building damage criteria…may occur at the foundation of receiving buildings”- This is only in reference to short term vibrations. The setback distances for long term vibrations should also be included.
Noted.
LA: We consider the radii presented to be appropriate for the various activities.

Auckland Council: Construction vibration is typically short term. The classification of vibration as either long or short term can only be made once measurements have been made and following an assessment of the response of the structure. No further detail required at this stage. Section 9.3
Text added to Section 9.3 in CNV DWP.
“If minor damage has occurred, such as cosmetic cracks, further mitigation will be applied if practicable. However, the activity can continue provided the measured vibration level is not exceeded further.” Auckland Council: Additional measures should be provided in this case, such as confirmation that no further damage will occur from a structural engineer as per Condition 38.4. Complaint management procedure 9 IPR: complaint management process not included in CNV DWP and cross referenced from CCP. Page 81
| Aotea Station Main Works
The information within Section 7.3.2 from the CCP has been included within the CNV DWP.
Construction Noise and Vibration Delivery Work Plan LA: Procedures relating to environmental complaints are detailed within Section 7 of the Communication and Consultation Plan. Auckland Council: Noise and vibration complaint procedure should be in the CNVDWP, or at least a summary. In addition, I have checked the CCP (section 7.3.2) and the complaint procedure is generic and may not be specific enough to deal with a noise or vibration complaint. We recommend that this is addressed by Link Alliance.
