1. Introduction

1.1 Background

The City Rail Link (CRL) project comprises the construction, operation and maintenance of a 3.4km twin-tunnel underground passenger railway, running between Britomart Station and the North Auckland Line (NAL) in the vicinity of Mt Eden Station. The proposed works include the construction of two underground stations, with a depth of up to 42 metres below ground. It will transform the downtown Britomart Transport Centre into a two-way through-station that better connects Auckland’s rail network, allowing it to double in capacity.

In 2017, City Rail Link Limited (CRLL) submitted an outline plan for canopy removal and utility relocation works within the Aotea Station area, along the western side of Albert Street between Victoria Street West and Wellesley Street West (Auckland Council ref. OPW60310921). This outline plan was accepted by Auckland Council without changes. Canopy removal works are currently being undertaken.

Additional utility relocation works are required beyond the footprint of the approved works. As such, CRLL is seeking authorisation for the utility relocation works beyond that which are currently authorised.

The CRL Enabling Works Contract 2.1 and 2.2 (C2.1 & C2.2) Construction Noise and Vibration Delivery Work Plan, prepared by Marshall Day Acoustics, dated 23 November 2017 (“the Approved CNVDWP”), and this addendum to the CRL C2.1 & C2.2 CNVDWP will be submitted to Auckland Council to support the authorisation of the works.

This addendum must be read in conjunction with the Approved CNVDWP.

1.2 Site Description

The project site applicable to this addendum is located in Auckland City Centre, within the road corridors of Albert Street, Victoria Street West and Kingston Street (as illustrated in Figure 1). The site adjoins the project area of the canopy and utility works authorised by consent number OPW60310921.

The area surrounding the project site is a dense urban environment with a built form comprised of medium to high rise buildings. Common land uses in the project area include commercial offices and services, residential apartments, retail, civic, hospitality, hotel accommodation and car parking. Along Albert Street active construction sites are present including for the CRL and private development. Buildings adjoin much of the project site boundary (road corridor) forming active frontages that provide access to private residences and businesses.

The project site is highly utilised by pedestrians and vehicles, both for private and business purposes. Albert Street and Victoria Street West are classified as a primary arterial roads and Kingston Street and Durham Street West are classified as local roads. Due to CRL works, Albert Street is currently operating with one lane in each direction.

1.3 Purpose of Addendum Report

Additional utilities are required to be relocated around the proposed Aotea Station beyond the footprint of the approved works. This Addendum has been prepared to cover the additional utility relocation works proposed. As much of the approved CNVDWP remains relevant, an Addendum has been prepared.

This addendum must be read in conjunction with the Approved CNVDWP.

2. Project Description

2.1

Overview

As part of the CRL project, it is proposed to undertake advance utility relocation works prior to the main construction activities around Aotea Station. Approval has been provided for the relocation of utilities between Victoria Street and Wellesley Street along the west side of Albert Street. The

Figure 1 Site location

physical works to relocate the utilities will be undertaken at the same time as the works described below.

Briefly, the area of Aotea utility relocation works will generally be along Albert Street, from Wyndham Street to Wellesley Street, with works extending into parts of Kingston Street and Victoria Street. The works are to be broken down into three stages.

2 Area of proposed works authorised works

2.1.1. Utility Relocation Works

It is proposed to undertake the utility relocation works in three stages.

For all stages the main element of the works is the formation of temporary trenches within footpaths to allow installation of new ducts and pipes for utility services. Once the ducts and pipes are installed the trenches are to be backfilled with the footpath reinstated.

The trenches will generally be 1m to 1.8m wide with an average depth of 1.5m to 3m. The utility relocation works will relate to electrical, telecommunication, gas, potable water, stormwater and wastewater assets.

Table 1 provides a summary of works proposed for each stage.

Table 1 Proposed works

Stage

Stage 1 Works will be located along the footpaths of Albert Street, between Wyndham Street and Victoria Street, extending into part of Kingston Street and Victoria Street. Trenching along Victoria Street will be to a depth of 1.5m. All other trenches will be around 2.5m to 3m in depth. The total length of trenches constructed will be approximately 340m resulting in approximately 1350m³ of spoil being removed.

Page 7 | Construction Noise and Vibration Delivery Work Plan

3 months (from September 2019 –November 2019)

Figure

Stage 2

Stage 3

Works will be located along the footpath of Victoria Street, between Albert Street and Elliott Street (on the south side of the street) with trenching being around 1.5m in depth.

Between Victoria Street and Kingston Street, on the western side of Albert Street, trenching will be around 2.5m in depth.

A support site compound will be provided in part of the car park of Bledisloe House (details provided below).

The total length of trenches constructed will be approximately 180m resulting in approximately 405m³ of spoil being removed.

Works will be located along the east side footpath of Albert Street (between the top of the ramp from Durham Street to the corner of Victoria Street) and the north side footpath of Victoria Street, between Albert Street and Elliott Street.

Works will also be undertaken on the north side of Victoria Street, between Federal Street and Albert Street.

The total length of trenches constructed will be approximately 180m resulting in approximately 585m³ of spoil being removed.

2.2 Construction Methodology

2 months (from November 2019 –January 2020)

1.5 months (from January 2020 – March 2020)

The construction methodology for the Stage 1-3 works will generally be based on the methodology approved for the utility relocation works along the west side of Albert Street, between Victoria Street and Wellesley Street (OPW60310921). The construction methodology is provided in the Construction Environmental Management Plan (CEMP) addendum.

In summary it is proposed to undertake utility relocation works for electrical, telecommunication, gas, potable water, stormwater and wastewater assets. Once the trench is formed, bedding will be placed in the trench, with the new utility ducts and pipes installed. Once installed, the trench will be backfilled with the surface of the footpath reinstated.

Table 2 provides a summary of the activities and equipment for the works.

Table 2 Construction methodology summary

Activity

Identify and mark-out position of trenches

Saw cut and remove existing pavement/ hardstanding.

Expose and support existing services between 1.5m and 3m depth.

Lay new power and communication ducts, stormwater and wastewater pipes, place and compact trench backfill

2.2.1. Project Programme

Equipment and Materials

Truck, hand held service locator

Concrete saw, handheld concrete breaker (only where necessary), excavator, truck

Hydro vac, normal excavator, truck

Trucks, plate compactor (no vibrating rollers)

The project is anticipated to take approximately 6 months to complete based on knowledge of underground services. Should complexity or additional services be encountered during the course of the project, then the project duration will extend beyond the 6-month time period, by up to 3 months.

2.2.2. Site layout and Management

Detailed site layouts for each stage of the works have been provided in Appendix G: of this document. Traffic Management Plans are provided as Appendix A of the TAPDWP document (Appendix F of the CEMP). These plans indicate the location of works, construction vehicle access points, traffic management layouts, position of the site compound including worker amenity buildings, pedestrian access, and access points for properties surrounding the work site.

A temporary construction site compound (Figure 3: Indicative layout of the Stage 2 Site Compound) will be formed on the corner of Wellesley Street and Mayoral Drive in the part of the Bledisloe House car park. This compound will be within the project designation boundary and will be established approximately from October 2019 (Stage 2), until March 2020. This site compound will be occupied by storage containers, the objective of the site compound is to provide a site that can be used as a rest area for workforce staff, and house equipment and vehicles during the works. Temporary fencing will be used to delineate the site, along with Link Alliance branded mesh scrim. Vehicle access will be via the existing entrance off Mayoral Drive and through the gate as marked on the plan. Containers are likely to include machinery equipment and a total of up to 1,200L (6x 20L drums) of diesel in bunds.

A SSCVMP will be required for a number of properties. These are identified and discussed further in Section 4.2 of this document.

As discussed in Section 3.1.2 above, the Auckland District Court is a Notable Receiver and will have a SSCNVMP prepared in accordance with designation condition 39.

4. Predicted Construction Noise and Vibration Levels

4.1 Noise

Indicative sound levels for the proposed equipment are presented in Table 4 of the C2.1 and C2.2 CNVDWP. Equipment used for the utility relocation works will be the same as that proposed for the C2.1 and C2.2 utility works.

Following a study of the proposed construction methodology, noise modelling for the utility relocation works has been undertaken. Noise levels are predicted to exceed the Project noise criteria at a number of receivers. Worst-case noise levels are likely to occur over a period of 1-3 days during each stage whilst utility relocation works are directly outside each receiver Noise levels may also exceed the Project noise criteria whilst works are directly outside neighbouring properties.

Noise contour maps showing worse case predicted noise levels are included in Appendix E: Noise level predictions for the site compound have not been undertaken as no noise generating activities will occur in this area.

As required by CRL designation condition 37, a SSCNMP will be prepared for any receiver or activity where construction noise is either predicted or measured to exceed the Project Noise Standards, except where the exceedance is less than 5 decibels and does not exceed:

a. 0700-2200: 1 period of up to 2 consecutive weeks in any 2 months; and

b. 2200-0700: 1 period of up to 2 consecutive nights in any 10 days.

For predicted exceedances of less than 5 decibels, monitoring shall be undertaken to confirm the actual noise levels. If exceedance is shown to be more than 5 decibels, or the period exceeds those detailed, then a SSCNMP must be prepared.

In addition to the properties identified in the C2.1 and C2.2 CNV DWP, SSCNMPs are required for the properties listed in Table 4.

Table 4 Properties requiring a SSCNMP

4.2 Vibration

Some construction activities are predicted to generate high levels of vibration including excavation, compaction and breaking. The setback distance from each of these activities has been calculated. If a receiver is located within the setback distance an exceedance of the building damage criteria may occur at the foundation of the building. Based on vibration measurements of similar equipment in use on the Contract 2 works, the excavator has the potential to generate the highest levels of vibration. The emission radii used to calculate the relevant setback distance is detailed in Table 5.

There are no vibration emitting activities associated with the site compound.

Table 5 Indicative vibration emission radii for construction equipment

Vibration contour maps for each stage of works are included in Appendix F:.

Several properties are located within the setback distances, these are identified in Table 6.

Table 6 Buildings located within setback distance

An SSCVMP is required for all properties identified in Table 6

Further to the above, Appendix 1 and 2 of the CRL designation conditions requires a preconstruction building condition survey for the following buildings in the vicinity of the utility relocation works in accordance with Condition 46:

• 74 Albert Street

• 4 Kingston Street

• 6-12 Kingston Street

Glossary of Acoustic Terminology

Sound Power Level, LWA

Ten times the logarithm to the base 10 of the ratio of the sound power radiated by a sound source to the reference sound power, determined by use of frequency-weighting network “A” (see BS EN 61672-1), expressed in decibels.

Equivalent Continuous A-weighted Sound Pressure Level, LAeq

Value of the A-weighted sound pressure level of a continuous, steady sound that, within a specified time interval T, has the same mean square sound pressure as a sound under consideration whose level varies with time.

A-weighting

A-weighting is used to replicate this sensitivity by modifying the electrical response of a sound level meter with frequency in approximately the same way as the sensitivity of the human hearing system.

Site Attributable Sound Level (also referred to as ‘site noise’ or ‘specific sound level’)

Sound in the neighbourhood of a site that originates from the site.

Free-field

External sound field in which no significant sound reflections occur (apart from the ground). NOTE

Measurements made 1.2 m to 1.5 m above the ground and at least 3.5 m away from other reflecting surfaces are usually regarded as free-field.

CRL Contract 3 Aotea Utility Relocation Works – Site Specific Construction Noise and Vibration Management Plan

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 CRL Contract 3 Utility Relocation Works (the ‘Project’). This SSCNVMP provides a specific assessment of construction noise and vibration from utility relocation works within the project designation.

This SSCNVMP should be read in conjunction with the CRL Contracts 2.1 and 2.2 Albert Street Canopy Removal and Utilities Diversion Construction Noise and Vibration Delivery Work Plan (CNV DWP) prepared by Marshall Day Acoustics (Document ref Rp 001 r06 20170511 dated 23 November 2017) as it contains further details of the project, noise criteria, monitoring, general mitigation measures and other information, and with the CRL Contract 3 Aotea Utility Relocation Works Construction Noise and Vibration Delivery Work Plan (CNV DWP addendum) relating specifically to Aotea Utility Relocation Works Stages 1-3, to which this document forms Appendix C. 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 utility relocation works are shown in Figure 1.

Figure 1 Site location

Receivers

2.1.1. Affected receivers

Receivers where noise and/or vibration levels due to the utility relocation works within the project designation have the potential to exceed project noise or vibration standards, along with the relevant building uses, are listed in Table 1.

Table 1 Affected receivers

*This is the Monday to Saturday 07:00 to 22:00 noise criteria. The majority of works will be carried out during this period. For residential receivers the noise limit is reduced to 65 dB LAeq & 80 dB LAFmax on Sundays and Public Holidays between 07:00 to 22:00 and to 60 dB LAeq & 75 dB LAFmax at all other times.

2.1.2. Bluestone Wall

In addition to the buildings detailed in Section 2.1.1 there is a wall with heritage status, referred to as the Bluestone Wall. The wall is located towards the northern end of the Project area opposite the District Court.

The vibration criteria of 3mm/s from DIN 4550:3 is applicable to heritage structures. DIN 4150:3 states that “Experience has shown that if these values are complied with, damage that reduces the serviceability of the building will not occur”. It also states that exceeding the values does not necessarily lead to damage. Table 2 details categories of damage and a description of the damage that could be expected in that category. Providing the vibration criteria of 3mm/s is achieved at the Bluestone Wall the Category of Damage will be 2 or below.

Table 2 Categories of Damage

2 Slight

Fine cracks easily treated during normal redecoration. Perhaps isolated slight fracture in building. Cracks in exterior visible upon close inspection.

Cracks easily filled. Redecoration probably required. Several slight fractures inside building. Exterior cracks visible, some repainting may be required for weathertightness. Doors and windows may stick slightly.

3 Moderate

Cracks may require cutting out and patching. Recurrent cracks can be masked by suitable linings. Brick pointing and possible replacement of a small amount of exterior brickwork may be required. Doors and windows sticking. Serviceability Damage

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 the CNV DWP addendum. 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. Façade performance and internal noise levels

4.1 Noise

The utility relocation works are located so close to a number of receivers that internal noise levels will be high. Use of the concrete saw, concrete breaker, plate compactor and hydro-vac has 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. The works are of a relatively short duration and cutting and breaking activities will only take place for a short time period. It will be necessary to consult further with each affected receiver before works begin so that noisy activities can be scheduled, where possible, for a time that least impacts them.

With the above 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 4 along with an estimate of the current façade performance and the worst-case internal noise levels during utility relocation works.

4.2 Vibration

In addition to the general noise and vibration control measures outlined in Section 5.0 of the CNV DWP, the specific vibration mitigation measures outlined in Table 5 should be implemented if the initial on-site vibration monitoring demonstrates that the building damage vibration limits will be exceeded.

Table 5 Vibration Mitigation Measures

Equipment/process

Excavators, bobcats, loaders

Excavator mounted rock breaker

Roller compactor (17t)

Grease tracks regularly

Avoid unnecessary revving of engines and banging of buckets on the ground.

Use smaller equipment where possible.

Use lower vibration generating equipment such as a handheld jack hammer

Use a smaller compactor, less than 10t

Site-specific vibration mitigation measures are included in Table 6.

Excavator mounted rock breakers must not be used within 16m of the Bluestone Wall unless on site measurements demonstrate vibration levels are lower than predicted from this item of plant. Hand held jack hammers or alternative low vibration generating equipment should be used within this distance. Similarly, small compactors, less than 10t should be used when within 15m of the Bluestone Wall.

5. Communication and Consultation

Section 6.0 of the CNV DWP details the communication procedures in relation to construction noise and vibration effects. The complaints process is detailed in Section 6.2 of the CNV DWP.

Consultation with the stakeholders identified in this SSCNVMP took place from mid-July to midAugust 2019. Topics that were covered included:

28 | CRL Contract 3 Aotea Utility Relocation Works – Site Specific Construction Noise and Vibration Management Plan

• Sequencing of construction activities

• Likely equipment and associated noise and vibration levels

• Proposed mitigation and management measures

• Construction of their buildings

• Operational hours of their businesses

• Operating environment that is required by the businesses

Further details of the meetings and comments made by the stakeholders are provided in Appendix D of the CNV DWP addendum.

6. Monitoring

Section 7.0 of the CNV DWP provides details of the methodology for noise and vibration monitoring.

6.1 Noise Monitoring

Noise monitoring will be carried out when use of the concrete saw and concrete breakers begins within 20 metres of the buildings detailed in Table 7. The monitoring will be carried out at first floor level unless we are unable to gain access.

Table 7 Noise Monitoring Locations

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, hand-held concrete breaker or plate compactor is first used within 10 metres of the building:

• 83 Albert Street

• 27-35 Victoria Street West

• 37 Victoria Street West

• 45 Victoria Street West

• 63 Albert Street

• 66 Victoria Street West

• 68 Victoria Street West

• 98 – 102 Albert Street

• 65 Albert Street (District Court)

• 4 Kingston Street

• 92 Albert Street

Vibration monitoring will be carried out at the following receivers when use of the excavator occurs within 5 metres of the building:

• 74 Albert Street

• 55-59 Victoria Street West

• 63 Albert Street

Condition Comments Response

36.2 To achieve this objective, the Construction Noise and Vibration DWP shall include:

(a) The roles and responsibilities of the noise and vibration personnel in the contractor team with regard to managing and monitoring adverse noise and vibration effects;

(e) The timing of construction activities that are likely to create an adverse noise and vibration effect;

Noise and Vibration Monitoring Manager not listed in Addendum (Table 3)

• Table 3 has been amended in CNV DWP addendum to include the noise and vibration monitoring manager.

(f) The location of sensitive noise and vibration receivers;

• A number of receivers are predicted to be exposed to levels exceeding the Project Criteria. A standard mitigation comment is: "Construction noise may be audible inside the building during these activities, however this will be intermittent and over a limited duration of only 1-3 days." This seems to be an unrealistic expectation of the speed of likely progress per stage and not considerate of the combined effect of multiple stages or works outside adjacent properties. For example: 63 Albert St has a frontage of 24m and facade levels of 90 dBA plus for Stage 1A, 83dBA for Stage 1B. Similar cases occur throughout due to the adjacent worksites but especially around the intersections.

• The actual durations should be more accurately established with assistance from the CRL project team, with a view to identifying the actual durations where the project criteria are going to be exceeded.

• Table 4 of the SSCNVMP needs updating with all receivers (refer other comments herein)

• The timeframe of 1-3 days is based on the information received from the Link Alliance contractor for the works. They have confirmed that this is realistic based on the proposed methodology.

• Text has been added to Section 4.1 to qualify the 1-3 days statement. We consider that the level of detail provided about the duration of works is sufficient.

• Table 4 of SSCNVMP has been updated.

• Further consultations have taken place since the peer review, and Appendix C of the CNVDWP has been

(h) Specific measures to address the concerns raised by those sensitive receivers;

• A number of receivers are not provided with expected exceedances or mitigation measures in Table 4 for various reasons (1-4). These should be fully completed prior to lodging.

• The contour maps should be fully completed to include all greyed buildings that are approaching or exceeding the Project Criteria. These sites are also not on the communication list.

• 34 Wyndham St

• 48 Wyndham St

• 57 Albert St

• 55 Albert St

• Mitigation measures are listed in the Site-Specific plans but are not well aligned with particular concerns so that it can be objectively seen that the mitigation listed will help alleviate concerns.

• The mitigation strategy for receivers exposed to levels beyond the Project Criteria should be optimised for those receivers with expressed sensitivity in the communication log and that are going to be over exposed for longer periods.

updated accordingly.

• For a number of properties, it has not been possible to communicate with the owner and manager in the timeframes given. These are identified in Appendix C of the CNV DWP and Table 4 of the SSCNVMP.

• Contour maps updated to include ‘Not Occupied Buildings’.

• Added.

(j) Methods and measures to mitigate adverse noise and vibration effects including, but not limited to, structural mitigation such as barriers and enclosures, the scheduling of high noise and vibration construction, use of low noise and vibration machinery, temporary relocation of affected receivers or any other measures or offer agreed to by the Requiring Authority and the affected receiver;

• No mention is made of localised enclosures for concrete cutting, nor do the predictions of noise reflect that. Refer main 5.4.2 of early works CNVDWP. It is understood that there may be practicality issues around this but none of that is covered in the DWP. Enclosures are clearly one of the most acoustically effective means of reducing concrete saw noise and if not appropriate for the works it should be clearly identified what has led to this decision and why they cannot be considered.

• Enclosures have proved impractical to-date on the Project. They were trialled for C2 works but were not practical/safe for the operator to use.

• The MDA CNV DWP for 2.1 and 2.2 works identifies a number of general and specific mitigation measures, including the use of enclosures. As the CNV DWP is an addendum to the MDA report, no further mitigation measures are suggested.

(iii) The timing and location for monitoring of buildings during construction is required (Note that the flow charts contained in Appendices B and C of Appendix J of the technical noise and vibration report provided as part of the Notice of Requirement should be used as a guide);

(iv) Identifying appropriate monitoring locations for receivers of construction noise and vibration;

(l) Cross references to the specific sections in the Communication and Consultation Plan which detail how landowners and occupiers are to be communicated with around noise and vibration effects.

37.5 SSCNMP’s will identify:

(a) The extent to which noise may exceed the Project Noise Standards in Condition 31 or the overpressure limits in Condition 32;

This should be itemised where appropriate for the SSCNVMP

• A monitoring section (Section 6) has been added to the SSCNVMP.

This should be itemised where appropriate for the SSCNVMP

DWP notes information is fed to Noise & Vibration Monitoring Manager but not beyond this.

• Appropriate monitoring locations are now detailed in Section 6 of the SSCNVMP.

• The reviewed document is an addendum to the approved CNV DWP. The addendum refers to the approved CNV DWP in relation to communication.

• Extent of external exceedance should be included in Table 1 of SSCNVMP

• The subjective descriptors of the 6065 dBA Leq internal limit ‘Annoyance

• Worst-case external, mitigated noise levels have been included within Table 4 of SSCNVMP. External noise levels are given in a 10 dB range, to remain consistent with the approved CNV DWP.

and reduction in work efficiency’ are different from the Approved works description of the same values being ‘Annoyance and degradation of communication quality’. These should be aligned. (refer 63 & 99 Albert St, 98-102 Albert St, 27-35, 69 & 71

Victoria St West, 39, 41 Victoria St West) We would expect the description of Annoyance and degradation in communication quality to be more accurate given the Leq represents an average over the period.

• The subjective description of 65-70 dBA for office spaces at 38 Wyndham St for first floor offices as ‘Annoyance and reduction in work efficiency’ does not seem correct (also in light of the point above).

(b) The timing and duration of any exceedance; Construction noise is frequently referred to as "intermittent and over a limited duration of only 1-3 days". This seems to be an unrealistic expectation of the speed of likely progress per stage and not considerate of the combined effect of multiple stages. Refer comments under 36.2(e)

(e) The methods and measures to mitigate noise effects, including but not limited to, potential to offer temporary relocation of affected receivers, alternative ventilation, façade sound insulation improvements, building condition surveys in the case of overpressure generated by blast events,` or other offers made by the Requiring Authority and whether these have been agreed to by the affected receiver;

• The works are proposed to be relatively limited in duration (duration TBC per 36.2(e) ) which would imply that some of the more intensive treatments are not reasonable. The main street works will take a number of months/years and would likely trigger these more significant mitigation measures. What scope is there to bring these more significant mitigation options forward to also protect these works?

• 52 Victoria St West level 1 offices SSCNMP refers to 99 Albert St, however level 1 of this building is a carpark. This assessment needs updating.

• Given the impact at 38 Wyndham St is going to be very significant if works are carried out during occupied hours, can any temporary interior changes such as respite zones or increased absorption be made to reduce the impact?

(f) The reasons why the management and mitigation measures and methods reflect best This should be better explained, particularly in relation to the high noise

• Noise level predictions and mitigation for the main works are outside of the scope of this document.

• 52 Victoria Street West details have been updated within SSCNVMP.

mitigation methods around concrete saws, hand-held breakers and hydro vacs. We understand there is a broad range of noise levels produced, in particular by Hydrovac units, and the easiest mitigation method is likely to be to simply ensure a quieter unit is used. These reasons should be informed by site monitoring results where relevant.

38.5 SSCVMP’s will identify:

(a) The timing and duration of any exceedance; Refer to comments under 36.2(e) regarding “1-3 days”.

(c) Site Specific vibration criteria that addresses the issue(s) of concern (i.e. building damage, amenity and sensitive equipment). Site Specific criteria shall be determined by a suitably qualified independent vibration expert;

(d) The summary of the communication and consultation undertaken with the receiver. The summary must include a clear explanation of where any comments have not been incorporated, and the reasons why not. This information must be included in the SSCVMP provided to both the Independent Peer Review Panel and Auckland Council as part of the Outline Plan process specified in Condition 11;

(e) The methods and measures to mitigate vibration effects, including but not limited to,

It is not clear what is being done with regards to actually addressing the issues for receivers like 37 Victoria St West, 41 Victoria St west etc. that have vibration concerns that seem more related to disturbance than damage of the structure (as would be the case for most retail tenants vs Landlords). Is this best handled through site specific monitoring, improved communications or other means?

Comments from receivers do not seem to reflect in mitigation measures. These should be aligned better.

• The timeframe of 1-3 days is based on the information received from the Link Alliance contractor for the works. They have confirmed that this is realistic based on the proposed methodology.

• A table outlining vibration mitigation measures table has been added in Section 4.2 of SSCNVMP.

(f) The reasons why the management and mitigation measures and methods reflect best practicable option.

39 Notable Receivers

39.3 The Requiring Authority shall consult with the notable receiver throughout the duration of construction and update the SSCNVMP as required to achieve the objective in 39.2.

The reasons should be provided • Added.

Auckland District Court is a Notable Receiver that was not affected by the Contract 2.1 and 2.2 works and was therefore not considered

It is understood (although not spelled out in the documents) that a previous SSCNVMP for this site was produced for the Contract 2 Works and this had various outcomes including installing double glazing and a resulting internal criterion of 40 dBA Leq.
