Historic Character Delivery Work Plan (Built Heritage)

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 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 Historic Character Delivery Work Plan (Built Heritage Section) (HC DWP (Built Heritage)) has been prepared in relation to the main construction works for the new Aotea Station.

1.1 Aotea Station Overview Once completed, the Aotea Station will include platforms, lifts, escalators, rooms for housing stations and tunnel services equipment, an entrance building at Wellesley Street, two additional entrance buildings at Victoria Street, a Plenum at Kingston Street, services, internal and architectural finishing’s, structural fittings, utilities services diversions and connections.

The location of the Aotea Station is primarily beneath 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 form the main entrance building to the Aotea Station (refer to Figure 1-2 below)1.

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 Auckland Council/ Panuku.

Historic Character Delivery Work Plan (Built Heritage) 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.

This DWP relates to managing affects upon built heritage during the construction of Aotea Station, mainly in relation to the formation of the station box (d-walling/ piling) and excavation.

Refer to Section 2 of the Construction Environmental Management Plan (CEMP) for a detailed description of the Aotea main works.

1.2 Historic Character DWP (Built Heritage Section) Staging To reflect the staged construction approach for Aotea Station, HC DWPs (Built Heritage) will be developed in stages.

This HC DWP (Built Heritage) addresses the Aotea main works, which are detailed in the CEMP, an overview is provided in Section 2 of this HC DWP (Built Heritage).

As required by condition 45, a separate Bluestone Wall Management Plan will be prepared, certified by the Heritage Advisory Group, and provided to Auckland Council. The purpose of the Bluestone Wall Management Plan is to manage the adverse effects on the heritage values of the Bluestone Wall during construction of the Aotea Station.

HC DWPs (Built Heritage) will also be prepared as part of the urban design and public realm reinstatement works.

1.3 Purpose of the Historic Character DWP (Built Heritage Section) This HC DWP (Built Heritage) has been prepared to identify the measures that will be implemented to mitigate and manage the potential adverse effects on built heritage during the Aotea main works.

The objective of this HC DWP (Built Heritage) is to avoid, remedy or mitigate adverse effects on built heritage as far as reasonably practicable.

This HC DWP (Built Heritage) addresses the requirements of CRL designation Condition 41 and will be implemented throughout the construction period.

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 DWPs will be prepared, describing the finishings and other permanent above ground public realm reinstatements. That Outline Plan package will address the relevant Urban Design related Designation conditions (condition 47 – 54, including landscaping (condition 55.3(c))).

Historic Character Delivery Work Plan (Built Heritage) This HC DWP (Built Heritage) has been developed to enable consultation with 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). A record of consultation outcomes (CLG and IPR) is included in Appendix D. This HC DWP (Built Heritage) has been prepared by Matthews & Matthews Architects Ltd and forms part of the CEMP for the main works.

Building Condition Surveys 46.1

Process for Building Condition Surveys Prior to construction, as a minimum those buildings listed in Appendix One and Appendix Two or identified pursuant to Condition 41.2(b) will be considered for a building condition survey. A building condition survey will be undertaken where it is assessed that there is potential for damage to buildings or structures arising from construction as determined by an independent suitably qualified person appointed by the Requiring Authority based on the criteria below unless the relevant industry criteria applied at the time or heightened building sensitivity or other inherent building vulnerability requires it. Building damage criteria will initially be assessed in accordance with Burland, J.B. (1997) “Assessment of Risk of Damage to Buildings due to Tunnelling and Excavation”.

Additional factors which may be considered in determining whether a building condition survey will be undertaken include: (a) Age of the building; (b) Construction types; (c) Foundation types; (d) General building condition; (e) Proximity to any excavation; (f) Whether the building is earthquake prone; and (g) Whether any basements are present in the building.

46.2

Where prior to construction it is determined that a Building Condition Survey is required in accordance with Condition 46.1, or if measurements exceed the criteria in Condition 33:

Aotea Main Works 2.1 Overview of Works

The Aotea main works will involve three main phases of work. Each phase of work involves multiple construction activities which will be undertaken throughout the Aotea project site. 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, Wellesley Street entrance structure, concourse, Victoria Street entrance structures and Kingston Street Plenum, and; Structural fitout of the Aotea Station including MEFH installation, and internal and architectural finishings.

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 public 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 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 Construction Methodology The Aotea main works will be divided into stages as described in the CEMP.

4. Overview of potential effects on Built Heritage during the Aotea main works Unreinforced masonry buildings, including the historic heritage and special character buildings and structures in proximity to the Aotea main works are likely to be at higher risk from the potential effects of vibration or ground movement associated with the works. These buildings may have soft mortar joints, simple foundations and connections of structural members or limited bracing. It is important to understand the specific building structure, including foundations, fabric and detailing, in order to inform the likely built heritage effects and the methods that shall be implemented during the works to avoid, remedy or mitigate these effects (outlined in Section 5 of this HC DWP (Built Heritage)).

4.1

Vibration

Vibration can affect nearby buildings and their foundations, with consequential damage to building fabric and services. Potential damage from vibration can range from cosmetic to minor or major damage. Potential effects on historic structures as a result of ground movement due to vibration include cosmetic or aesthetic effects such as hairline cracks to surfaces or to mortar joints that might affect appearance, through to changes to building fabric that might affect weather tightness, alignment of windows and doors, or damage to services. Major damage could place buildings at risk in terms of structural stability. For built heritage places, even aesthetic damage may impact on heritage values, for example if original details or finishes are cracked or damaged, and potentially if inappropriate repairs to such defects are undertaken.

A Construction Noise and Vibration Delivery Work Plan (CNV DWP) (Appendix L of the CEMP) has been prepared to address the effects of the Aotea main works. Some construction activities are predicted to generate high levels of vibration including sheet piling, excavation, compaction and breaking.

Construction activities required for the Aotea main works will need to be carefully managed through this DWP, and the CNV DWP in accordance with relevant Conditions.

4.2

Ground Movement

Excavation and foundation work can also cause ground displacement and movement of an adjacent historic structure. Excavation deeper than the foundations of neighbouring historic buildings has the potential risk of such movements occurring. A historic structure, with a shallow masonry footing, may experience corresponding displacement that can result in major structural damage. Managing the risk and potential effects of ground movement or settlement is addressed in the Groundwater and Settlement Monitoring and Contingency Plan (GSMCP).

The GSMCP forms part of the CEMP for the Aotea main works, and addresses the relevant matters specified in the conditions of Water Permit R/REG/2016/1892 (groundwater diversion and discharge) (‘the Consent’).

As described in the GSMCP, Building Condition Surveys will be carried out for all structures listed in Appendix 2 of the Consent, including those buildings in the Aotea Station area. The surveys will be undertaken to establish a baseline building condition against which any subsequent surveys can be compared. Buildings will be assessed according to foundation type, construction and sensitivity to ground movement. The outcome of the investigations and monitoring will determine any mitigation measures to be implemented to control settlement to the building foundations.

Historic Character Delivery Work Plan (Built Heritage)

4.3

Stormwater Drainage

Maintaining a well-functioning stormwater drainage system is essential to the protection of any historic structure. This system can easily be rendered ineffective by construction or demolition work if debris originating at the construction site finds its way to the rainwater disposal system or drains of an adjacent building, with potential to adversely impact on heritage fabric through flooding.

4.4

Impact Damage

Construction activities have potential to cause accidental damage to building fabric through direct impact from machinery. Appropriate protection and management are required to avoid this.

4.5

Built heritage Potentially Impacted by the Aotea main works

Table 8 in Section 5.2 of the CNV DWP identifies the buildings in proximity to the Aotea main works including heritage buildings that may be at risk of receiving vibration which exceeds the building damage vibration limits.

Section 6.2 of the Groundwater and Settlement Monitoring and Contingency Plan (GSMCP) identifies the buildings for which Building Condition Surveys are required, including heritage and special character buildings.

Historic Character Delivery Work Plan (Built Heritage)

5.

Management and Mitigation Measures

Potential impacts on built heritage in proximity to construction activities are considered as part of the CNV DWP and the GSMCP for the Aotea main works. The performance standards for construction induced settlement specified in the Consent Conditions will be met through the specific design aspects of the main works, along with management, monitoring, mitigation and contingency measures set out in the GSMCP. Methods to be implemented during construction to avoid, manage or mitigate potential impacts on built heritage include: • Building Condition Surveys prior to the commencement of works; • Investigations of building foundations prior to the commencement of works; • Monitoring of vibration and ground/building movement, and mitigation and contingency measures as set out in the CNV DWP and GSMCP; • Built heritage protection where appropriate; and • Building record and salvage strategy (with respect to the removal of any built heritage items) (refer to Section 5.1.1 and 6 of this HC DWP (Built Heritage)).

5.1

Building Condition Surveys 5.1.1. Pre-Construction Surveys

Prior to construction, condition surveys of identified built heritage (refer

Table 3-1) (inclusive of those buildings listed in Appendix 2 of the CRL designation conditions) will be undertaken. These condition surveys will ascertain any pre-existing damage to a building, existing structural distress, and any potential weakness of the structure’s foundations or structural elements, as well as non-structural damage. The condition surveys will form the basis for recording buildings and recording baseline information prior to works commencing.

The building condition surveys will generally be undertaken as follows (in accordance with CRL designation condition 46): • •

The building surveys will be undertaken by an independent senior qualified person.

The survey shall include: • • • • •

Any information about the type of foundations; Existing levels of damage (aesthetic, superficial, affecting levels of serviceability); Whether observed damage is associated with structural damage; Susceptibility of building or structure to further movement; and Photographic evidence.

With respect to built heritage, the pre-construction condition surveys will include: • •

A survey of the exterior and interior of heritage buildings.

A record of the condition of buildings using photographs, annotated drawings and written records, noting any existing signs of structural distress and damage or deterioration of a non-structural nature. | Aotea Station Main Works

Historic Character Delivery Work Plan (Built Heritage) • •

•

Consideration of the stability of any elements, including applied decorative elements or features, and any fragile elements.

Any recommended remediation to secure or mitigate potential problems prior to the commencement of construction based on consideration of the heritage character and detail of the building.

The location of all cracks greater than 2 mm in aperture width, which shall be recorded with a positional accuracy of +/- 200 mm. Installation of grid crack monitors may be required on selected readily accessible cracks with an aperture width greater than 2 mm discussed above and as determined in consultation with the Built Heritage Specialist.

The condition surveys shall generally include: •

• • • • • • • •

An introduction with overview of the premises, record of when the inspection was made, orientation notes for viewing photos and captions, summary of the scope of inspection, purpose of report and any limitations, any areas not accessed; A description of the property construction, based on a visual inspection and review of available architectural drawings and property information obtained from Council; A summary of existing damage and susceptibility to future damage; Site plan; Annotated plans, elevations and sections that relate to the photographic record; Floor plans if available; Burland building damage classification matrix; Pre-Construction Condition Schedule, with description, visible damage evident, damage category recorded and photograph reference; and Annotated photographs recording building condition. This should include general exterior and interior views as well as photographs of specific defects.

The building condition surveys will be reviewed by the Project Built Heritage Specialist, prior to works commencing.

5.1.2. Surveys during Construction As set out in the CNV DWP, building condition surveys may be undertaken during the construction works in the event that complaints in relation to building damage are received or if the vibration criteria set out in the CRL designation conditions are exceeded.

In addition, the Link Alliance shall carry out visual inspections of the surrounding ground and external facades of buildings for which pre-constriction condition surveys are required adjacent to the early works to monitor any deterioration or movement of any pre-existing cracks, as described in the GSMCP. The GSMCP also requires continuous measurement of any ground surface or building movement during construction (refer Section 5.2.1 below).

5.1.3. Post Construction Surveys Post-construction survey shall comprise a repeat of the required elements of the pre-construction survey so that a direct comparison can be made. In accordance with CRL designation Condition 46.4, building condition surveys of those buildings or structures that were subject to a pre-construction building condition survey may be undertaken post-construction of the works. Where a postconstruction building condition survey confirms a building has deteriorated as a result of the works, the damage shall be rectified by the Link Alliance.

5.2 Building Record Strategy Where heritage buildings or structures are directly affected by the works, a comprehensive record will be made before, during and after construction works. This section describes the building record methodology that will be implemented in any locations of built heritage directly affected. Refer Section 5.1 of this HC DWP (Built Heritage) for further detail regarding pre - and post-construction surveys of built heritage. Buildings and structures that are directly affected by the Aotea main works include the Bluestone Wall and Toilets and heritage and special character buildings where canopies must be removed.

Refer Section 6 for matters regarding the Bluestone Wall and Toilets.

5.2.1. Building record The following recording level will be undertaken for identified built heritage adjacent to the main works in any locations directly affected: a) b) c) d) e)

Prior to any works an archival photographic record should be made of buildings or structures directly affected.

Existing drawings should be assembled (if held in public records).

Measured drawings relevant to elements directly affected by the works.

Written records, including recording of changes/alterations, composition and finish of materials.

Research and collate existing archival photography where this exists.

5.2.2. Measured Drawings Measured drawings should be prepared for all relevant elements and record materials, detail and finishes, to suitable scale as indicated in Table 5-1.

Page 24

| Aotea Station Main Works

Historic Character Delivery Work Plan (Built Heritage) General Images - conventional (digital) photography will be used with appropriate professional lenses capable of producing high resolution 1- 2Mb JPEG images5.

Archival images - For archival images the camera should be set to record using a raw file format. This raw file should not be modified - it should be considered to be the ‘digital negative’. It is recommended that these images be converted to uncompressed baseline v.6 TIFF for archiving. All images should have accompanying metadata specifying: photo ID, capture device, converting software, colour space, bit depth, resolution, date of capture, photographer, caption and any alterations made to the image.

Video equipment shall be high-resolution (broadcast quality), with low light capabilities although additional lighting may also be required.

Photographic recording should include: Context: Views showing relationship to the surrounding setting, other buildings and streetscape.

Exterior: Elevations, roof where practicable, typical elements (chimneys, windows, doors, parapets, details, fixtures).

Interior: General views of interior layout, individual rooms/spaces, interior elevations, typical elements (windows, doors, details, fixtures and fittings), features such as staircases, evidence of use, wear and changes made, chattels and artefacts).

5.3

Monitoring and Management Measures 5.3.1. Groundwater and Settlement Monitoring Methodology

Based on the results of the pre-construction building condition surveys, and in accordance with the GSMCP, geotechnical and structural monitoring instrumentation will be installed on surfaces of, and nearby to, existing structures. This will include ground and building survey monitoring marks installed along the areas affected by the main works. The location and number of monitoring marks will take into account the building type/size, accessibility and risk of damage from ground settlement.

This will allow any actual building movement to be monitored and compared with the estimated potential effects.

The purpose of this instrumentation will be to measure/monitor any movement, settlement, tilt, strain and induced vibrations as a result of the works which may have the potential to adversely affect the structure. The instrumentation will be installed prior to starting the construction works. Should monitoring indicate the exceedance of specified movement trigger levels, then the GSMCP also sets out an appropriate intervention and mitigation strategy.

5.3.2. Vibration monitoring and management Vibration mitigation and management, based on a Best Practicable Option (BPO) approach will be implemented during the works as outlined in the CNV DWP, including undertaking building condition surveys (refer to Table 9 in Section 5.2) and monitoring prior to and during construction.

Heritage New Zealand Pouhere Taonga; AGS1 Guidelines for investigation and recording of buildings and standing structures, November 2018.

Page 25

| Aotea Station Main Works

Historic Character Delivery Work Plan (Built Heritage) Regular monitoring and assessment of the vibration measurements will determine the process to be followed and any required action to mitigate and manage any potential effects, as set out in Section 8 of the CNV DWP. If vibration monitoring demonstrates non-compliance with the vibration building damage limits the construction activity responsible for the exceedance shall cease as soon as safe and practicable to do so, construction methodology, mitigation and management strategies will be reviewed, advice will be sought from a structural engineer and a detailed building condition survey shall be undertaken by a suitably qualified engineer.

Any damage to buildings or structures shall be recorded as set out in Section 9.3 of the CNV DWP. Recording shall include photographs and relevant annotated plans, sections and elevations to show the major features of the buildings including location, type, construction, age and present condition, including defects (cracks). A report shall be prepared summarising the findings of the survey and recording.

5.4

Protection Methodology during construction activities

Table 5-2 outlines the methodology to be implemented to protect key features of historic (and other) buildings against construction activities undertaken adjacent to, or in close proximity to these buildings.

Table 5-2: Overview of Protection Methodology

Built Heritage Feature Exterior fabric and surfaces of buildings and structures (including the Bluestone Wall)

Canopies and overhangs

Fragile exterior or interior building elements

Historic streetscape elements

Protection Methodology Where works will be undertaken immediately adjacent to exterior fabric and surfaces of buildings and structures (including the Bluestone Wall), appropriate protection such as plywood sheets or temporary fencing to a minimum of 2 metres high will be required.

Avoiding impact from machinery movement through use of appropriate equipment and observation while works undertaken under or adjacent to canopies.

Appropriate bracing or protection for features such as parapets, chimneys, stained glass and leadlight windows, if vibration or ground settlement will be likely to put these at risk.

Elements, such as basalt kerbs, or basalt blocks inset into the footpaths shall be carefully removed if required, prior to or during the works and stored for reinstatement at an appropriate time following the completion of works. Cellar lightwells should be retained and protected with plywood as required during the works.

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

5.4.1. Managing Maintenance Works to Heritage Buildings during the Construction Works The construction team will work with building owners to facilitate necessary building maintenance and repair works during construction should monitoring/inspections confirm this is needed. The Link Alliance Communications team will arrange the process to manage maintenance works.

Bluestone Wall and Toilets

The 1881 Bluestone Wall, stairs, gate, fence, lamps and toilets are scheduled in the Auckland Unitary Plan (ID 01906) as a Category B historic heritage place.

During phase 4 of the works (approximately between September 2020 and December 2020), the Bluestone Wall will be deconstructed to accommodate the construction of the station. Once the necessary station works are complete, the Bluestone Wall will be reconstructed (approximately between July 2022 and November 2022).

Excavation is required behind and below the level of the wall to construct the tunnel box. The reinstated wall will be strengthened and supported in conjunction with the tunnel piling and tunnel box structure. The Bluestone Wall Management Plan will be produced in accordance with condition 45 and will be certified by the Heritage Advisory Group and provided to Auckland Council. The purpose of the Bluestone Wall Management Plan is to manage the adverse effects on the heritage values of the Bluestone Wall during construction.

A contractor with experience in heritage projects has been engaged to individually label, remove and safely store the stone blocks and other elements including the stairs, kerbs, piers and cast-iron balustrade. The wall will be re-erected in its new position, with each stone and element placed back in the exact order of the original wall6. The Bluestone Wall will be fully scaffolded for this operation with access to Durham Lane remaining.

Work in Albert Street in the area of the Bluestone Wall includes piling with a capping beam installed on the west side of Albert Street. Excavation follows, east of the piled wall, with removal of the Bluestone Wall in layers. Piling with a capping beam is installed to the east side of Albert Street, followed by further excavation, construction of the tunnel box including its roof, and reinstatement of the Bluestone Wall7.

The Bluestone Wall Management Plan will be prepared to manage adverse effects on the heritage values of the wall. The Management Plan will confirm the key heritage values of the wall8, and summarise alternative construction methods to ensure an approach with the least impacts on the heritage value of the wall, within the practical constraints of constructing the project. The Management Plan will include the methodology for recording, deconstructing and reconstructing the Bluestone Wall, including: • • • • • • • 6

recording in situ, prior to any change (archival photographic record/ point cloud scan/ /photogrammetry/ measured drawings). recording and drawings for the deconstruction phase- annotated drawings and photographs with every block/element numbered. drawings for reconstruction- in conjunction with new structural work, as well as reinstatement of missing sections, repairs.

Physical numbering of every block, and sections of balustrade ready for deconstruction.

Deconstruction and pallet storage, in layers/sections.

Transport and off-site storage.

Reconstruction phase.

Summary The Bluestone Wall was constructed in 1881 following the widening of Durham Street, incorporating men’s' toilets. Constructed from locally available bluestone by the wellknown contractor Daniel Fallon, it is technically accomplished and uses standard construction methods for its period. The wall and stairs have been little modified since 1881 and retain their integrity. The toilets, however, have been substantially altered over time. Features of note include decorative cast-iron screens in the toilets. The structure is a well-known landmark in this part of town, terminating the vista up Durham Street West, and providing a distinctive edge to Albert Street.
