1. 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 (NAL) 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.

In May 2020 Auckland Council confirmed the Outline Plan and associated Construction Environmental Management Plan (CEMP) and Delivery Works Plans (DWPs) for the Aotea Station main construction works (‘Main Works’). This document is an addendum to the Main Works CEMP1 and provides an overarching framework for the management of construction effects associated with the public realm reinstatement (PRR) phase of works.

This addendum has been prepared to detail the construction methodology and address the potential environmental effects associated with the PRR phase of the construction works that were not covered in the Main Works CEMP. Where necessary, this CEMP addendum (the CEMP – PRR addendum) details any further provisions which are required in relation to the PRR works that are not already provided for in the Main Works CEMP. In some instances, it has been appropriate to prepare addendum documents to the respective Main Works DWP also (refer Table 1.1).

Where project details, procedures and protocols are already covered in the Main Works CEMP and are directly applicable to the PRR works, reference is made to the appropriate section of the Main Works CEMP. Accordingly, the CEMP-PRR addendum for Aotea Station should be read in conjunction with the certified Main Works CEMP, and the associated delivery works plans and

2. Aotea Station Public Realm Works

2.1 Overview of Works

This chapter provides a description of the PRR works, which are not included in the Aotea Station Main Works CEMP.

The Aotea Station public realm works extend along Albert Street from Wyndham Street (end of the C2 works site boundary) to the southern end of the Aotea Station Designation 2500-1 located adjacent to 10 Mayoral Drive. This includes sections of intersecting roads including Victoria Street, Wellesley Street, Kingston Street, and Durham Street. The extent of the works area is shown in Figure 2.1 below.

The construction works required to reinstate the permanent aspects of the public space include paving, sealing, tie-in works, stormwater treatment, the installation of street furniture and landscaping. The works will be undertaken in a staged manner (with five main stages), commencing as the current construction works are progressively completed (refer Section 2.2).

A description of each of the key activities relevant to this addendum is provided in Section 2.3

2.2 Construction Staging

The PRR works are divided into five main ‘stages’ as illustrated in Table 2.1. Note that the various phases overlap for some of the works, which is reflected in the total duration of works, being approximately 18 months. An overview of the PRR construction staging is provided in Figure 2.1 and Appendix A.

2.3 Construction Methodology

2.3.1. Overview

Generally, the PRR works will consist of:

• Construction of new stormwater infrastructure

• Installation of utilities

• Construction of tree pits

• Installation of new road pavement

• Installation of new footpath pavements

• Landscaping works

• Installation of road furniture

• Reinstatement of canopies

2.3.2.

Stormwater Infrastructure

New stormwater catchpits, lines and drains are being installed to capture stormwater runoff from the road and footpaths. The new stormwater infrastructure is within the road carriageway and connects into the existing stormwater network.

The stormwater construction works will be staged to construct the main drainage lines, manholes and connections first. Generally, these works start from the downstream connection points and are laid ‘uphill’ to the head of the new drainage line. Once the main drainage lines are completed then the Aco drains, catchpits and leads will be constructed – with the works staged in accordance with the construction phase drawing (Appendix A) and associated traffic management

Figure 2 1: Overview of Construction Staging

Plant used for the stormwater works includes excavators (5T-20T), trucks for spoil disposal and importing backfill materials, concrete trucks, compaction equipment (plate compactors and/or small rollers), trench shields and hand tools. Due to the limited space available on the site, materials will be delivered to site as they are required for the construction works.

2.3.3.

Utilities

A new network of utilities will be required to service the public realm installations and divert main utilities back into permanent alignments. This will include low voltage for lighting and fibre and copper cabling.

Duct installations will be completed using 5 – 14t excavators, trucks for spoil disposal and importing backfill materials, concrete trucks, compaction equipment (plate compactors and/or small rollers), trench shields and hand tools. Due to the limited space available on the site, materials will be delivered to site as they are required for the construction works.

Linked to this utility duct and cable work will be the installation of street lighting and other above ground traffic service installations.

2.3.4.

Tree Pits

Several tree pits will also be constructed for new planting installations. Locations of this are provided in the Urban Design DWP. Many of the tree pits are in close proximity to services and in some cases 25mm steel plates are to be installed to provide an additional root barrier between the tree pits and service trenches. During excavation, as utilities are approached, hydro excavation and pothole techniques will be used to expose them. Excavation around the utility will be undertaken, leaving enough material to support it temporarily. Where required, temporary supports will also be installed around the utilities.

Tree pits will be excavated to depth using excavators (5T-20T) with the excavation battered to provide a safe working zone. The excavations will be around 1-2m deep.

Plant used for the tree pit works includes excavators (10-20T), trucks for spoil disposal and importing backfill materials, compaction equipment (plate compactors and/or small rollers), trench shields and hand tools. Due to the limited space available on the site, materials will be delivered to site as they are required for the construction works.

2.3.5.

Road Pavement

Once the substantial below ground works are completed in each area, the road pavement works will commence. Subsoil drains will be constructed along the edges of the road carriageway, followed by the kerb construction, then subgrade and basecourse layers.

Testing will be undertaken on the subgrade and basecourse layers during construction to confirm the requirements of the civil specifications and drawings have been achieved.

The basecourse material will be placed directly from trucks, and spread and compacted using excavators, graders and plate / roller compactors. The road will be constructed in stages providing the necessary live traffic lanes, vehicle access to properties and maintaining pedestrian and cycle access.

Once the basecourse layers are complete, then the structural asphalt layers will be constructed. Specialist asphalt subcontractors will undertake these works using asphalt paving plant. The final

50mm layer of AC14 will not be placed until the final phase of the works. This is to ensure no damage to the final layer and to provide a consistent finish with fewer visible joints. Line marking works will be completed once the final asphalt layer has been placed.

2.3.6. Footpath Pavements

The footpath pavements will commence in an area once the utilities works, tree pits and kerbing have been completed. Footpath pavements generally consist of basecourse layer, reinforced concrete layer and decorative paving layer.

The footpaths will be constructed in phases, with pedestrian access (1.5m wide) and access to properties maintained. The pedestrian routes will generally be kept close to the building walls, but will be moved within the work zone to allow the works adjacent to the buildings to be completed. At all times the pedestrian access routes and live work zones will be separated by appropriate safety barriers (e.g. fencing).

Testing will be undertaken on the subgrade and basecourse layers during construction to confirm the requirements of the civil specifications and drawings have been achieved.

The basecourse material (cement treated basecourse) will be delivered to the worksite as required by trucks and spread and compacted using small excavators (5-10T), and small roller or plate compactors. Concrete delivery for the structural concrete layer will be by truck, with concrete pumps (Line or boom) used as required. The concrete layer will be constructed in segments to maintain pedestrian movements and suit the constraints of the site. A watering system shall be used to control dust from the placement of fill and bedding material as well as during compaction.

Decorative paving works will involve cutting and placing stone pavers and mixing and placing of Steintec bedding or similar A watering system shall be used to control dust from extraction and any cutting operations. A mobile acoustic enclosure shall be used where practicable for any paver cutting. Materials for these works will be kept on site (in limited quantities as required) and mixed and cut to fit in designated areas of the work zone.

2.3.7. Landscaping

Landscaping works consist of planting, including tree planting in the completed tree pits (refer 2.3.4) This will be one of the final activities and will be completed from the adjacent traffic lane, where they are located in the footpath. Trees will be delivered by truck and planted by hand or using a Hiab crane. Surface tree grilles or permeable covering will be installed once trees have been planted.

2.3.8. Road Furniture

Road furniture includes street lighting and signage, traffic signals, seating, rubbish bins, and bicycle racks. Foundations and utilities supplies for these items will be completed during the previous stages of these works. The installation of road furniture will be one of the final activities undertaken in each area.

Road furniture will generally be delivered to site and installed immediately. Installation will be carried out by specialist installers using hand tools, and Hiab crane for lifting larger items.

Commissioning and testing of the electrical items (e.g., streetlights, traffic signals) will be carried out by specialist electricians in accordance with the specifications and local authority requirements.

2.3.9. Reinstatement of Canopies

Canopies previously removed as part of the early works (Stages 4 and 5) phase will be reinstated as part of the PRR works. These will be reinstated to the same or better standard than existing prior to the works being undertaken.

These works will include builders works, painting and electrical services and will include canopies on 44 Wellesley St, 37 Albert St, and 98 – 102 Albert Street.

2.4 Programme

The PRR works are anticipated to take approximately 18 months to complete and will commence from mid/late – 2022.

2.5 Hours of Work

Construction will be as per those outlined in Section 2.5 of the Main Works CEMP. Works will generally be undertaken Monday to Saturday, 0700 – 1900 hrs. However, certain activities may need to be undertaken outside these hours to minimise traffic impacts or minimise disruption to businesses or residents, such as network utility works where the NUO requires works to be undertaken at night, or the delivery of large plant.

To maintain pedestrian access to business and properties, night works may be required for the installation of pavers. Night works shall be limited to the placing of pre-cut pavers. Cutting of pavers shall be undertaken during daytime construction hours.

2.6 Site layout and management

The Aotea CSA (located at Bledisloe House car park) will service the PRR works, with the area of the CSA reducing as the PRR works proceed until operation of the CSA is no longer required. Once the CSA is no longer required, the area will be stabilised for the future OSD construction. This will be to an agreed state with the OSD developer. Construction of the OSD is programmed to commence August 2024 following the completion of the PRR works.

Key activities within the PRR works areas shall include:

• Liquid waste and solid waste storage and collection (e.g., contaminated water, used chemicals, liquids and slurry from spill clean-up, “slops and slurry” skips) from active work zones

• Asphalt pavement construction equipment

• Fuel storage for pumps, generators etc.

• Use and storage of diesel pumps and compressors

• Use and storage of concrete pumps

• Use and storage of mobile generators

• Concrete breaking

• Storage of construction materials such as steel reinforcing cages, pre-cast concrete elements, geotextiles, formwork (timber and steel), bagged cement, paving materials

• Site offices and construction personnel amenities including portaloo or similar

• Stormwater/groundwater containment and/or treatment facility

• Vehicle movements between active work zones and construction support areas.

The site office, site parking, and compound site security and safety, along with site housekeeping will be as per the Main Works CEMP until no longer practicable, or required, depending on the progress of work and associated constraints.

2.7 Site Security, Safety and Public Viewing

There is no change to the protocols for managing security, safety and public viewing outlined in the Mains Works CEMP.

3. Social and Environmental Management

3.1 Construction Activities and Associated Environmental Receivers

The key construction activities associated with the Aotea Station PRR Works are summarised in Table 3.1 below.

These activities have the potential to generate adverse environmental effects relating to network utility disruption, social and business disruption, transport access and parking, noise and vibration, dust, stormwater discharges, soil contamination, and built heritage.

Table 3.1. Construction activities and associated environmental receivers

Main activities

5. Environmental Management

The Main Works DWPs and Management Plans continue to detail the controls and measure for each of the environmental aspects of the PRR works as specified in Section 5 of the Mains Works CEMP. Furthermore, the following sections identify the environmental aspects associated with the construction of the PRR works with any additional operational controls and mitigation measures specific to the PRR works identified.

5.1 Network Utilities

Consultation and co-ordination with Network Utility Operators will continue to be managed in accordance with the general processes outlined in Section 5.1 of the Main Works CEMP.

5.2 Social Impact and Business Disruption

The PRR works will not change the level of potential adverse social or business disruption effects from the activities identified in the Social Impact Business Disruption (SIBD DWP) In addition, the potential effects of the PRR works don’t extent beyond the ‘affected community’ identified in the Main Works SIBD DWP.

A such, there is no change to the general processes for managing social impacts and business disruption (SIBD) as identified in Section 5.2 of the Main Works CEMP, with additional mitigation to be implemented as outlined in this CEMP Addendum.

5.3 Communication and Consultation

The general processes outlined in the Communication and Consultation Plan2 (CCP) will be used to ensure appropriate communication and consultation with the community, stakeholders, affected parties and affected in-proximity parties occurs during the PRR works as identified in Section 5.3 of the Main Works CEMP.

It is noted that since the Main Works CCP was written a new drop in information hub (Te Pūkaki) has opened beside the Aotea Station site. This is open to the public 11am – 1pm weekdays where people can ask questions and find out more about the City Rail Link, the construction activities occurring at Aotea, and upcoming construction milestones. This will be available for the public during the PRR phase of works.

5.4 Erosion and Sediment Control

There is no change to the general processes for managing erosion and sediment generation as identified in Section 5.4 of the Main Works CEMP.

The Main Works Erosion and Sediment Control Plan (ESCP) follows the principles of Auckland Council GD05. Erosion and sediment control measures will be installed prior to the start of any land

2 It is noted that the Main Works CCP did not reference the building owners identified in Condition 15.4 (xi), (xii), (xiii). The CCP is now being updated to reference these owners specifically through the annual review process as required by Condition 22.1. While these owners were not referenced in earlier CCP documents, engagement and consultation has occurred with parties through the wider Aotea communications process and through specific property and neighbourhood engagement.

disturbance works. The mitigation measures will remain in place until reinstatement of active working areas is complete. General ESC measures include:

• Catchpit/stormwater inlet protection (e.g., covering catchpit grates with geotextile to filter sediment laden runoff);

• Chemical treatment (used to improve the efficiency of sediment retention devices e.g., automated chemical dosing);

• Dewatering devices (devices used to pump out water that collects within open trenches);

• Diversion channel/bund (install to divert runoff from external catchments entering construction areas e.g. hotmix diversion bunds);

• Filter socks (with or without flocculation, to intercept and impound runoff);

• Sand logs/coir logs (use in carriageway to divert clean water from construction site);

• Settlement tanks (for storage of sediment-laden runoff); and

• Stabilised entrance and surface (vehicle movements on sealed surfaces, vehicle accesses to be kept clean, stabilise entrance ways using aggregates).

A Flocculant Treatment Management Plan (FTMP) has been prepared as part of the Mains Works ESCP. PRR works will be undertaken in accordance with the measures identified in the FTMP.

5.5 Air Quality

The main discharges to air that will arise from the PRR works is dust. The following dust generating activities associated with the PRR works have been identified:

• Breaking up and excavating the existing footpath;

• Placement of fill/bedding material;

• Excavation of tree pits;

• Cutting of pavers/kerbstones;

• Concrete cutting; and

• Placement of soil

Apart from the cutting of pavers and concrete as described below, the other activities will be undertaken in accordance with Section 5.5 of the Main Works CEMP and the Air Quality (AQ) Delivery Work Plan

5.5.1.

Mitigation measures

The dust prevention methods outlined in Table 5.1, will be used as applicable to control dust emissions from the cutting of pavers and curb stones, in all areas of the Project. The list is not exhaustive and additional methods which are found to be effective may be used.

Some of the particulate generated by the cutting of pavers and kerbstones has the potential to be respirable quart/crystalline silica which, when uncontrolled, presents some health risks. These risks are controlled through the mitigation proposed in Table 5.1.

Source of Dust Control

Pavement Removal

Placement of Bedding Material

Cutting of Pavers

- Use water as necessary to control dust from extraction and any cutting operations.

- As far as practical excavated material is to be loaded directly into trucks.

- Use water as necessary to control dust from the placement of fill and bedding material as well as during compaction.

- As far as practicable all pavers and curb stones will be cut using equipment fitted with water dust suppression.

- Where it is not possible to use water suppression vacuum extraction systems shall be fitted to the cutting/grinding equipment.

- Solid barriers can also be placed around cutting activities to minimise wind effects.

- Alternatively, enclosures may be required (to mitigate noise).

Monitoring of these dust generating activities will be in accordance with the requirements of the AQ DWP. This includes daily visual inspections.

5.6 Trees and Vegetation

There is no change to the existing processes for managing potential adverse effects on trees and vegetation as identified in Section 5.6 of the Main Works CEMP.

It is noted no further trees are proposed to be removed as part of the PRR works, however protocols are relevant to existing trees to ensure they are appropriately protected during works.

Trees and vegetation are to be installed as described in Section 2.3.4 and 2.3.7. Details of types and location of trees and vegetation is addressed in the Urban Design DWP

5.7 Transport, Access and Parking

A Transport Access and Parking DWP Addendum (Appendix B) has been prepared to specify the methodology during the PRR works. The addendum identifies the transport configurations (including traffic layouts and movements, pedestrian access, property access and parking) for each of the construction configurations of the PRR works.

The five stages of the PRR works have been broken into further sub-stages for the purpose of traffic management planning (refer Section 4) and have been assessed to comply with relevant CRL designation conditions. The relation between the Main Works stages and PRR stages are outlined in the following table.

Albert St / Victoria St West and Albert St / Wellesley St West intersections both open with one lane in each direction.

Same as above.

The effects of the PRR stages on the road network, especially in terms of travel time impacts on inner city bus services are described in Section 5 of the Aotea Main Works TAP DWP. The effects to on-street parking and loading spaces will be as outlined in Section 6 of the Aotea Main Works TAP DWP. The processes and responsibilities in relation to monitoring for the PRR works are consistent with that for the Main Works, as detailed in Section 7 of the Aotea Main Works TAP DWP.

Together with the specific measures to manage the PRR work set out in the TAP DWP - PRR Addendum and the general management measures in the TAP DWP, adverse transport, access and parking effects will be appropriately mitigated.

5.8 Construction Nose and Vibration

Construction noise and vibration will continue to be managed in accordance with the general processes for managing construction noise and vibration as outlined in Section 5.8 of the Main Works CEMP and detailed in the Main Works CNV DWP

Various construction equipment and activities will act as noise and vibration sources during the PRR phase of works, such as excavators, concrete breakers, concrete saws, compactors and trucks. Details of this equipment is provided in Section 4 of the CNV DWP.

General noise and vibration management and mitigation measures are proposed to be implemented throughout construction to avoid, where practicable, exceedances of the noise and vibration criteria.

18 | Aotea Station – Public Realm Reinstatement

These are listed in Section 6 of the CNV DWP and include the use of noise barriers and enclosures where noise limits are predicted to be exceeded. Additional measures for each notable receiver during the PRR phase is provided in a Site-Specific Construction Noise Vibration Management Plan (SSCNVDWP) (Appendix C) The SSCNVMP for the PRR works provides additional detail on the use of mobile acoustic enclosures that may be used to mitigate the effects from stationary plant, such as paver cutting stations

Monitoring of noise and vibration is detailed in Section 8 of the CNV DWP and will be undertaken during construction when noise or vibration has the potential to exceed the limits or in response to noise or vibration complaints.

Engagement with affected parties will continue to be undertaken as detail in Section 7 of the CNVDWP.

5.9 Light Spill and Glare

There is no change to the existing processes for managing construction lighting as identified in Section 5.9 of the CEMP.

5.10 Historic Character

5.10.1.

Built Heritage

The PRR works has the potential to affect historic buildings and historic streetscape elements, as identified in the Aotea Station Main Works Historic Heritage DWP – Built Heritage.

The PRR works will be undertaken in accordance with Section 5.10.1 of the Main Works CEMP and the general management measures outlined in the Historic Heritage DWP – Built Heritage This includes methods to monitor the works (as set out in the CNV DWP, SSCNVMP and GSMCP) and to protect heritage fabric during construction phases. This includes the use of plywood to protect building fabric, use of bracing for parapets, chimneys etc and careful removal of basalt kerbs for reuse.

Protection measures shall be reviewed by the Project Built Heritage Specialist prior to works commencing and periodically during the works.

5.10.2.

Archaeology

The PRR works will be undertaken in accordance with Section 5.10.2 of the Main Works CEMP and the general management measures outlined in the Historic Heritage DWP – Archaeology.

Two recorded archaeological sites are located within the PRR works area, one being along the eastern side of Albert Street between Wyndham Street and Victoria Street (R11/3078; bluestone wall, stairs and toilets). The other is a backfilled or capped off well (R11/1182) within the CSA3

It is noted that the deconstruction and reconstruction of the scheduled Bluestone Wall located on Albert Street (near the Durham Street West intersection) is the subject of a Bluestone Wall Management Plan (confirmed by Auckland Council on 15 October 2020) in accordance with designation condition 45. The wall has now been deconstructed and will be reconstructed 1.5m

3 The Historic Heritage DWP – Archaeology required that the Project Archaeologist monitor the initial earthworks in the station entrance area.

19 | Aotea Station – Public Realm Reinstatement

further to the east once the necessary station construction works are complete (approximately between July and November 2022). The work associated with the Archaeological recording of the wall has been undertaken and is provided for in Section 6 of the HC DWP (Archaeology Section).

The PRR works will result in shallow excavations only and is unlikely that subsurface archaeological remains will be exposed. However, the possibility that subsurface pre-1900 or early 20th century archaeological remains may be exposed during the PRR phase will be mitigated and managed through the implementation of the HCC DWP (Archaeology Section) and an Archaeological Authority (no. 2017/793) granted by Heritage New Zealand Pouhere Taonga (HNZPT) for the wider CRL project (“the HNZPT Authority”).

Measures to mitigate impacts on archaeological remains include:

• Archaeological Discovery Protocols;

• Mana Whenua Protocols;

• Recording of Features and Deposits;

• Artefact Management Plan;

• Stand down periods;

• Post-excavation analysis and archiving; and

• Reporting requirements.

5.11 Urban Design

An Urban Design Delivery Work Plan (Urban Design DWP) has been prepared by the PRR works and the design of the Aotea Station including entrances and associated buildings. The Urban Design DWP is required to ensure that the areas within the designation footprint used during construction are restored and permanent works associated with the CRL are developed in accordance with urban design principles.

5.12 Public Art

The PRR works do not directly affect public art. Accordingly, as stated in Section 5 12 of the Main Works CEMP, a Public Art DWP is not required for these construction works.

5.13 Contaminated Soils

The existing management approach to the disturbance of any contaminated, or potentially contaminated material encountered during the PRR work, and the management of any associated human health or environmental effects will be undertaken in accordance with Section 5.13 of the Main Works CEM and the Main Works Contamination DWP.

5.14 Groundwater and Settlement

Due to the shallow nature of excavations required for the PRR works, groundwater is not expected to be encountered. As stated in the Assessment of Settlement Effects Report4 , a GSMCP is not required for the PRR works.

4 Appendix E of the Aotea Station Main Works Groundwater and Settlement Monitoring and Contingency Plan, prepared by the Link Alliance, dated 22 June 2020

Page 20 | Aotea Station – Public Realm Reinstatement

If groundwater is encountered, groundwater and settlement monitoring will be undertaken in accordance with the Main Works GSMCP.

5.15 Hazardous Substances

Hazards substances will be kept on site within specified hazardous substance storage areas at the site construction compound (within Bledisloe House car park). No additional hazardous substances will be required for the PRR works, from that listed in the Main Works CEMP.

The storage and use of hazardous substances will be managed in managed in accordance with Section 5.15 of the Main Works CEMP and the relevant provisions of the Industrial and Trade Activities Environmental Management Plan (ITA EMP) Any spills on site will be managed in accordance with the General Spill Response Plan provided as Appendix C to the ITA EMP.

5.16 Industrial and Trade Activities

Industrial trade activities will be managed in accordance with Section 5.16 of the Main Works CEMP and the relevant provisions of the Industrial and Trade Activities Environmental Management Plan. This includes activities such as vehicle refuelling, concrete washout, and the management of hazardous substances. Any spills on site will be managed in accordance with the General Spill Response Plan provided as Appendix C to the ITA EMP.

5.17 Building Condition Surveys

Building condition surveys (BCS) were required to be undertaken prior to the Main Works construction phase commencing, in accordance with designation condition 46 and resource consent condition 109. Due to the shallow nature of excavations required, no additional building condition surveys are required prior to the commencement of the PRR phase of works. Post construction condition survey requirements will be undertaken as identified in Section 5.17 of the Main Works CEMP.

5.18 Waste Management

There is no change to the existing processes for waste management as identified in Section 5.18 of the Main Works CEMP.

5.19

1. 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 (NAL) 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.

This addendum to the Aotea Station Main Works Transport Access and Parking Delivery Work Plan (TAP DWP)1 has been prepared to address any potential effects associated with the public realm reinstatement works (PRR) phase of construction works.

This addendum should be read in conjunction with the Aotea Station Main Works TAP DWP. Where project details, proposed management and effects are already covered in the Aotea Station Main Works TAP DWP and are directly applicable to the PRR works, reference is made to the appropriate section of the Aotea Station Main Works TAP DWP

2. Project Description

This section presents a summary of the PRR works to provide context to the TAP DWP Addendum. A detailed description of the PRR works is provided in the Aotea Station PRR Construction Environmental Management Plan (CEMP) Addendum. Further detail on the PRR works is also provided in the Aotea Station and Public Realm Reinstatement Urban Design Delivery Work Plan (Urban Design DWP).

Figure 1.1 CRL Route and Location

2.1 Construction Methodology Overview

The PRR works extend along Albert Street from Wyndham Street to the southern end of the Aotea Station Designation 2500-1 located adjacent to 10 Mayoral Drive. This includes sections of intersecting roads including Victoria Street, Wellesley Street, Kingston Street, and Durham Street. The extent of the works area is shown in Figure 2.1 below.

The construction works required to reinstate the permanent aspects of the public space include paving, sealing, tie-in works, stormwater treatment, the installation of street furniture and landscaping. The works will be undertaken in a staged manner (with five main stages), commencing as the current construction works are progressively completed. Refer to the CEMP Addendum for a further detailed description of the works.

2.2 Construction Programme

The PRR works are divided into five ‘phases’ as illustrated in Table 2.1. Note that the various phases overlap for some of the works, which is reflected in the total duration of works, being approximately 18 months.

Stage 2 –

Street - Public realm works along Victoria and at the intersection with Albert Street.

- Public realm works around the station entrances on Victoria Street.

The five stages of the PRR works are equivalent to Traffic Stages 3, 4, 5 and 6 of the Aotea Main Works TAP DWP.

3. Existing Transport Conditions

The traffic volumes of the roads nearest to where the PRR works will be undertaken are shown in Table 3.1. These volumes were obtained from the Auckland Transport (AT) online database on 15 March 2021.

Table 3 1 – Traffic volumes on main roads adjacent PRR works

The surveyed volumes are considered applicable for the 2022 and 2023 years given that the lane capacity for these roads remains the same and that the CBD area is generally operating at capacity during the peak periods

Further details of the existing transport environment are provided in Section 3 of the Aotea Main Works TAP DWP.

4. Proposed Traffic Management

The five stages of the PRR works are divided into further sub-stages for the purposes of construction and traffic management planning. These sub-stages of work are sequenced from north to south along the line of the CRL twin tunnels, starting at Wyndham Street and finishing at Mayoral Drive. The overall traffic management sequencing plan is shown in Figure 4.1

Details for each sub-stage will be included in the Traffic Management Plans (TMP) that will be submitted to AT approximately two to four weeks prior to construction works starting. Traffic Resolution documents will be prepared where changes to legal traffic and parking controls are required to support the approval and implementation of certain TMPs

The indicative traffic management layouts for each sub-stage are provided in the following report sections.

4.1 Albert Street – between Wyndham Street and Victoria Street West (Stages 1A, 1B, 1C)

PRR Stages 1A, 1B and 1C comprise of the reinstatement of the northern Albert Street section that is between Wyndham Street and Victoria Street West.

The indicative traffic management layout for Stage 1A is shown in Figure 4.2.

Figure 4 1 – Sequencing plan for the traffic management of the PRR works

The Stage 1A works are located on the western side of Albert Street. One northbound traffic lane will be provided on Albert Street while southbound traffic movements will be facilitated via the existing slip lane. Pedestrian access to properties on Albert Street and Kingston Street will be maintained at all times via either existing footpaths or protected on-road diversions around work zones.

The indicative plan for Stage 1B is shown in Figure 4.3.

Stage 1C is the same as Stage 1B for vehicular and pedestrian movements on Albert Street and Kingston Street. However, vehicle access from Durham Street West to Albert Street will be provided on the northern section of the Albert Street slip lane while works are undertaken on the southern section of the slip lane. An existing traffic signal will facilitate vehicles exiting the slip lane at the intersection of Albert Street / Wyndham Street.

4.2 Victoria Street West – between Federal Street and Elliott Street (Stage 2)

The PRR works on Victoria Street West will be undertaken during the long term closure of the Albert Street / Victoria Street West intersection and within the work zone established for the closure. The indicative traffic management layout for Stage 2 is shown in Figure 4.5.

4.5 - Indicative traffic management layout for Stage 2

Vehicle movements through the intersection will not be provided during the closure. Instead a culde-sac layout with a turning head will be provided on both Albert Street approaches to the intersection and the Victoria Street eastern approach. The Victoria Street / Federal Street intersection will operate as a T-junction during this phase.

Pedestrian and cyclist (will be required to dismount) access will be maintained through the intersection and for access to properties interfacing the closure area. During the closure of the Victoria Street West / Albert Street intersection, Wellesley Street West and its intersection with Albert Street will be fully open with two lanes provided in each direction on Wellesley Street West.

4.3 Albert Street – between Victoria Street West and Wellesley Street West (Stages 3A, 3B)

Stages 3A and 3B comprise the reinstatement of the southern Albert Street section that is between Victoria Street West and Wellesley West. This work will be undertaken during the closure of the Victoria Street West / Albert Street intersection. The indicative traffic management layout for Stage 3A is shown in Figure 4.6

Figure

Figure 4 6 - Indicative traffic management layout for Stage 3A

Two vehicle lanes, one in each direction, is provided on Albert Street between Victoria Street West and Wellesley Street West. Vehicle access to the Huawei Centre and Crowne Plaza forecourts will be maintained between the work zones.

The pedestrian footpath on the western side of Albert Street will remain open while a protected onstreet pedestrian path will be provided on the eastern side of Albert Street for pedestrian throughput and access to the Huawei Centre and Crowne Plaza buildings.

The indicative Stage 3B plan is shown in Figure 4.7.

4.7 - Indicative traffic management layout for Stage 3B

Similar to Stage 3A, two traffic lanes are provided on Albert Street, one in each direction with vehicle access to properties on the eastern side of Albert Street, restored to pre-CRL conditions. Pedestrian access to properties on the western side of Albert Street are maintained at all times between work zones.

4.4 Wellesley Street West – between Federal Street and Elliott Street (Stages 4A, 4B)

The reinstatement of Wellesley Street West will be undertaken in two general stages: Stage 4A and 4B. Two vehicle lanes, one in each direction, will be maintained on Wellesley Street West in both stages. Victoria Street West and its intersection with Albert Street will be open with the final configuration of one traffic lane in each direction on Victoria Street West, based on the Te Ha Noa –Victoria Street Linear Park project by Auckland Council

Stage 4A comprises works on the southern side of Wellesley Street West as shown in Figure 4.8.

Traffic Stage 6

Same general layout as for previous PRR Stages but either the Albert St / Victoria St West intersection closed to vehicles while Albert St / Wellesley St West intersection is open with two lanes in each direction as per Traffic Stages 3 and 4, or with the Albert St / Victoria St West and Albert St / Wellesley St West intersections both open with one lane in each direction as per Traffic Stage 6

Albert St / Victoria St West and Albert St / Wellesley St West intersections both open with one lane in each direction.

Same as above

As a general requirement of CRL DWPs, the transport modelling of the Aotea Main Works TAP DWP will be reviewed for relevancy in March of each year and updated as necessary It is expected that any specific modelling for the PRR stages would be undertaken outside of the Main Works assessment, should material changes to the PRR traffic management methodology be identified following the submission of the annual TAP DWP update.

6. Assessment of Effects

The scope of the PRR traffic management needs to comply with the relevant CRL designation conditions. Specific conditions for Aotea Station are detailed in Conditions 27.1 and 27.2. By way of summary, the PRR stages described in Section 4 of this report have been assessed to comply with the designation conditions.

Of particular significance, is Condition 27.1(c) which requires two fully operational traffic lanes in each direction at two of the Customs Street, Victoria Street and Wellesley Street intersections with Albert during the period when the third of those intersections is otherwise fully closed.

This will be achieved by undertaking PRR works on Victoria Street West during its established closure at Albert Street from mid-2021 to mid-2023 as part of the Main Works.

The PRR works for Wellesley Street West will be undertaken from mid-2023 onwards, maintaining one lane open in each direction. During this time, the public realm works on Victoria Street West will be mostly completed, with one lane open in each direction as per its final Linear Park configuration. This concurrent arrangement of having both Wellesley Street West and Victoria Street West open with one lane in each direction satisfies Condition 27.1(c), which maintains a combined total of two lanes eastbound and two lanes westbound across the two roads at their intersections with Albert Street.

Pedestrian and cyclist access to properties will be maintained at all times as required by the general condition 25.2(b), which fulfils the specific access requirements of Conditions 27.1 and 27.2.

On-going vehicle access to private property will be maintained to the greatest extent possible as required by the general condition 25.2(c). Specific requirements of Conditions 27.1 and 27.2 will be satisfied.

The effects of the PRR stages on the road network, especially in terms of travel time impacts on inner city bus services are described in Section 5 of the Aotea Main Works TAP DWP. The acceptability of the anticipated delays will be determined by AT prior to the approval of TMPs. Should anticipated delays to any bus services be a concern, then targeted mitigation measures will be discussed and agreed with AT during the development of a specific TMP.

The effects to on-street parking and loading spaces will be as outlined in Section 6 of the Aotea Main Works TAP DWP Changes required to these parking and traffic controls for a duration longer than three weeks will typically be addressed through the Traffic Resolution approval process, which may result in changes to the extent of the parking impacts.

In general, provided that the specific TMPs for the PRR stages comply with the relevant designation conditions captured in the Aotea Main Works TAP DWP, then AT will have sole-discretion over the transport effects of the TMPs to enable its approval.

Where there is conflict between a TMP and designation conditions further discussion will be required with AT and Auckland Council to resolve the appropriate traffic management measures.

Further Transport Specialist inputs may be required occasionally, such as for assessments against relevant designation conditions for specific TMPs, preparation of traffic resolution documents and assessment of effects not covered by either this PRR TAP DWP or the Aotea Main Works TAP DWP These inputs would be made on an as-needed basis.

7. Travel Time / Congestion Monitoring

The travel time and congestion monitoring requirements for CRL are set out in designation condition 26. The processes and responsibilities in relation to monitoring for the PRR works are consistent with that for the Main Works, as detailed in Section 7 of the Aotea Main Works TAP DWP.

8. Consultation and Communication

The scope of the consultation and communication requirements for PRR works are consistent with that established for the Main Works, as detailed in Section 8 of the Aotea Main Works TAP DWP

The Link Alliance communications and engagement team will work with the construction and traffic management teams to ensure that the requirements set out in this TAP DWP are achieved.

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 table1 .

Construction hours will be as per those outlined in Section 2.5 of the Main Works CEMP. Works will generally be undertaken Monday to Saturday, 0700 – 1900 hrs. However, certain activities may need to be undertaken outside these hours to minimise traffic impacts or minimise disruption to businesses or residents, such as network utility works where the Network Utility Operator (NUO) requires works to be undertaken at night, or the delivery of large plant.

1 The table will be updated as part of the CNV DWP annual review process.

To maintain pedestrian access to business and properties, night works may be required for the installation of pavers. Night works shall be limited to the placing of pre-cut pavers and asphalt paving. Cutting of pavers shall be undertaken during daytime construction hours.

4. Façade performance and internal noise levels

4.1 Noise

The Public Realm Reinstatement works are located close to a number of receivers that internal noise levels will inevitably 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 Public Realm Reinstatement works, e.g. during use of the concrete saw and concrete breaker Noise levels will reduce from those presented in Table 3 during other construction activities.

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.

5. Communication and Consultation

Section 7 of the CNV DWP details the communication procedures in relation to construction noise and vibration effects. The complaints process is detailed in Section 7.2 of the CNV DWP.

Consultation between the Link Alliance and the stakeholders identified in this SSCNVMP took place from early September 2019 regarding the Main Works phase. Topics that were covered included:

• 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 C of the CNV DWP.

Table 3 has identified where further consultation is required prior to works commencing.

6. Monitoring

Section 8 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 excavation begins within 20 metres of the buildings detailed in Table 6. The monitoring will be carried out at first floor level unless access is unable to be arranged.

Table 6 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.
