Introduction

The City Rail Link (CRL) project comprises the construction, operation and maintenance of a 3.4km underground passenger railway, running between Britomart Station and the North Auckland Rail Line (NAL) near Mt Eden Station. CRL Enabling Works commenced in December 2015 and the procurement of the main works contract (C3 Alliance) is being progressed with contract award likely in the first quarter of 2019. To allow works to commence as soon as possible upon award of the C3 Alliance, City Rail Link Limited (CRLL) are obtaining the necessary authorisations for demolition of buildings in the Karangahape Station construction support area (CSA) and active construction zone (ACZ).

This Historic Character Delivery Work Plan (DWP) relates to the demolition of properties in the Karangahape Station (Mercury Lane entrance) CSA. This is an advanced package of work on the CRL Project’s critical path, proposed to be completed in time to allow unimpeded access to subsequent main works construction under C3.

This advance works project is for the pre-construction phase of the work only. The physical demolition works are proposed to be undertaken by the C3 Alliance.

1.1

Project Works

It is proposed to demolish all buildings and structures in the Karangahape Station CSA (“the Project”), as identified in Figure 1.1 below. The Project is being undertaken in accordance with the CRL Designation 2500-4, confirmed in November 2015 and the Aotea Station to North Auckland Line (A2NAL) suite of resource consents approved in November 2016. The conditions of these authorisations require the preparation of an Outline Plan (OP), Delivery Work Plans (DWP) and Management Plans (MP). This Historic Character DWP (Archaeology Section) is prepared in accordance with the CRL Designation and resource consent conditions and identified in the hierarchy of documentation illustrated in Figure 1.2.

The properties to be demolished are: •

9A, 9B, & 9C Mercury Lane

•

11-13 Mercury Lane

•

17-21 Mercury Lane

•

23-31 Mercury Lane

•

38 East Street

•

20-24 East Street

Partial demolition will be required at the following properties: •

16D & 16E East Street

•

18 East Street

With the exception of the properties at 23-31 Mercury Lane, 38 East Street and 16 & 18 East Street all properties in the demolition area are owned by CRLL and the current tenancies are under CRLL management.

2 CRLL plan to commence the process of vacating the properties in the third quarter of 2019. This will be done to ensure that all properties are vacant in reasonable time ahead of the planned disconnection of services. Demolition will commence in late 2019 and extend for 8 to 12 weeks.

Demolition will be undertaken in a staged manner the order of which is to be confirmed by the C3 Alliance. Buildings at the northern end of the site are anticipated to be removed first, with demolition works progressing southward. All buildings and structures will be removed to ground level, with the retention of some existing foundations where necessary for site stability. A soft strip (wall linings etc) of salvageable materials and recycling of concrete and reinforcing steel will be carried out where possible. All demolition material will be removed from the project area and covered during transportation and disposed of at approved facilities.

The project area will be fenced, with lockable gates, to prevent unauthorised entry. Where appropriate, solid plywood fencing will be used, with appropriate signage prohibiting unauthorised entry and identifying hazards

Historic Heritage Values - Archaeology

2.1

Archaeological Sites in the Project Area

None of the buildings scheduled for demolition are archaeological sites of pre-1900 date as defined under the HNZPTA and Auckland Unitary Plan. No subsurface archaeological sites have been identified beneath the buildings scheduled for demolition. However, the properties at 9A, 9B, 9C, 11-13 and 17-21 Mercury Lane, where buildings are to be demolished, are known to have contained buildings during the 19th century, remains associated with which may be present subsurface. The buildings remained on the site until the mid-20th century and it is also possible that historic heritage remains relating to the early 20th century may be present subsurface.

As the advance works provided for in this DWP will be limited to site clearance following building demolition, the potential for impacting on subsurface pre-1900 archaeological remains or significant 20th century historic heritage remains will be limited.

However, the possibility of exposing subsurface pre-1900 archaeological remains or early 20th century historic heritage remains will be managed through this DWP and an Archaeological Authority (no. 2017/793) issued by Heritage New Zealand Pouhere Taonga (HNZPT) (see Appendix A).

Roles and Responsibilities

3.1

Project Archaeologist roles and responsibilities

The Project Archaeologist will be responsible for ensuring that the archaeological requirements set out in this DWP and in the Heritage New Zealand Pouhere Taonga Act 2014 (HNZPTA) authority are fulfilled. This includes ensuring that an archaeologist is available to inspect the properties at 9A-21 Mercury Lane at the end of demolition and during site clearance, and to respond to call-in by the construction contractor if any suspected archaeological remains are exposed. It also includes ensuring that the archaeological team adheres to the contractor’s site safety requirements.

The Project Archaeologist will also be responsible for reporting to the relevant parties regarding the archaeological work.

3.2

Contractor briefing

Prior to the start of building demolition, the Project Archaeologist and Mana Whenua representatives will meet with the demolition contractor(s) on site to brief them on the archaeological and cultural requirements for the Project.

The Project Archaeologist must be given at least two weeks’ notice by the contractor that demolition works at 9A-21 Mercury Lane are about to begin. The construction contractor will keep the Project Archaeologist informed as to the work schedule and any changes that may arise.

As set out in sections 5.2, 5.3, 5.5 and 5.8 of this DWP, the construction contractor will temporarily cease works and call-in the Project Archaeologist if suspected archaeological remains are exposed during site clearance when an archaeologist is not present, so that the remains can be assessed and recorded.

As set out in sections 5.3 and 5.7 of this DWP, the construction contractor will give the Project Archaeologist sufficient time and opportunity for the recording and sampling of any archaeological features or deposits encountered, and will not resume clearance works in the immediate vicinity until the archaeological work is completed.

Training

4.1

Pre-Construction Briefing

Prior to the start of Project works, the Project Archaeologist will provide a briefing on the Project’s archaeological requirements as contained within this section of this DWP to the construction contractor and all staff working on the Project. These requirements include but are not limited to: •

Statutory requirements under the HNZPTA;

•

How to recognise archaeological material (of pre-1900 or early 20th century date) if exposed during site clearance;

•

What actions need to be taken should any archaeological material or remains be exposed or encountered during site clearance; and

•

Who to contact in the event of archaeological material being exposed, if the Project Archaeologist is not present on site at the time.

Mana Whenua representatives will also be invited to provide a briefing on cultural requirements in case archaeological remains relating to Māori occupation are exposed during the clearance works.

4.2

Toolbox Talks

The Project Archaeologist will also attend regular toolbox meetings during the course of the Project, the purpose of which will be to remind staff of the Project’s archaeological requirements and to ensure that any new staff joining the Project team are fully briefed prior to the commencement of works.

4.3

Training Records

A record of attendance at briefing and training sessions will be held by the Environmental and Sustainability Manager as part of the Project training record (refer to the CEMP for further detail in this regard).

Archaeological Procedures and Mitigation Measures

5.1

9A-21 Mercury Lane

An archaeologist will be present during the final demolition of the buildings and site clearance, in case any subsurface archaeological features are exposed.

If any subsurface archaeological features (of pre-1900 or early 20th century date) are exposed at the site clearance stage, these will be investigated, sampled and recorded. If the feature is deep or extensive, and can be safely covered and protected in situ, investigation may be deferred to the main works stage.

5.2

Archaeological Discovery Protocols

As noted in section 2, there is only limited potential for subsurface archaeological remains to be exposed elsewhere during project works, which will be limited to building demolition and site clearance. However, the possibility that archaeological features and deposits may be exposed during site clearance works will be managed and mitigated by call-in by the contractor; the recording of any remains exposed; and the recovery of samples of archaeological material for further analysis.

As above (5.1), if the feature is deep or extensive, and can be safely covered and protected in situ, investigation may be deferred to the main works stage.

If suspected archaeological remains (of pre-1900 or early 20th century date) are encountered, works will stop in the immediate vicinity of the find until the Project Archaeologist can assess the site.

5.3

Discovery of Archaeological or Cultural Remains

If in situ archaeological features or deposits (of pre-1900 or early 20th century date) are identified during clearance works, the Project Archaeologist will stop works in the immediate vicinity by notifying the Project Manager and will investigate and record the remains, in accordance with accepted archaeological practice as set out in this DWP and the requirements of the HNZPT Authority. If the feature is deep or extensive, and can be safely covered and protected in situ, investigation may be deferred to the main works stage. If remains indicating MÄ ori occupation are exposed the protocols outlined in section 5.4 of this DWP will be followed.

If significant archaeological features or deposits are identified during clearance works the Auckland Council (Cultural Heritage Implementation Team Leader and Compliance and Monitoring Officer), HNZPT, and Mana Whenua will first be notified by the Project Archaeologist, and the remains will then be investigated and recorded in accordance with accepted archaeological practice and as directed by HNZPT, if of pre-1900 date. Any significant remains of 20th century date will also be investigated and recorded as directed by the Auckland Council Cultural Heritage Implementation Team Leader. If remains indicating Maori occupation are exposed the protocols outlined at section 5.4 of this DWP will be followed.

5.4

Mana Whenua protocols

5.4.1

Archaeological Remains

If archaeological remains relating to MÄ ori occupation are exposed, the Project Archaeologist will inform the appropriate Mana Whenua representatives.

5.4.2

KĹ?iwi Tangata (Human Remains)

If bone material is identified that could potentially be human, the following protocol will be adopted:

10 •

Earthworks/investigation will cease in the immediate vicinity while an archaeologist establishes whether the bone is human;

•

If it is not clear whether the bone is human, work shall cease in the immediate vicinity until the Auckland University reference collection and/or a specialist can be consulted and a definite identification made;

•

If bone is confirmed as human (kōiwi tangata), the archaeologist will immediately contact the Mana Whenua representatives, HNZPT, the NZ Police and Auckland Council Cultural Heritage Implementation Team Leader and Compliance and Monitoring officer;

•

The site will be secured in a way that protects the kōiwi as far as possible from further damage;

•

Once the NZ Police and HNZPT are satisfied that the remains are archaeological, consultation will be undertaken between the Mana Whenua representatives, the HNZPT Regional Archaeologist, the Auckland Council Cultural Heritage Implementation Team and City Rail Link Limited (CRLL) to determine and advise the most appropriate course of action. No further action will be taken until responses have been received from all parties, and the kōiwi will not be removed until advised by HNZPT;

•

The Mana Whenua representatives will advise on appropriate tikanga and be given the opportunity to conduct any cultural ceremonies that are appropriate;

•

If the Mana Whenua representatives are in agreement and so request, the bones may be further analysed by a skilled bio-anthropological specialist prior to reburial, in line with the HNZPT Guidelines Kōiwi Tangata Human Remains (2010); and

•

Activity in that place can recommence as soon the bones have been reinterred or removed and authorisation has been obtained from HNZPT.

5.4.3

Taonga (Māori Artefacts)

Māori artefacts such as carvings, stone adzes, and greenstone objects are considered to be taonga (treasures). These are taonga tūturu within the meaning of the Protected Objects Act 1975. Taonga may be discovered in isolated contexts, but are generally found within archaeological sites. If taonga are discovered the following protocols will be adopted: •

The area containing the taonga will be secured in a way that protects the taonga as far as possible from further damage, consistent with conditions of the Archaeological Authority (no.

2017/793);

•

The Project Archaeologist will then inform HNZPT, Auckland Council and the nominated Mana Whenua representatives so that the appropriate actions (from cultural and archaeological perspectives) can be determined;

•

These actions will be carried out within the stand down period specified below, and work may resume at the end of this period or earlier if advised by HNZPT or the Project Archaeologist;

•

The Project Archaeologist will notify the Ministry for Culture and Heritage of the find within 28 days as required under the Protected Objects Act 1975. This can be done through the Auckland War Memorial Museum; and

•

The Ministry for Culture and Heritage, in consultation with Mana Whenua, will decide on custodianship of the taonga. If the taonga requires conservation treatment (stabilisation), this can be carried out by the Department of Anthropology, University of Auckland (09-373-7999) and would be paid for by the Ministry. It would then be returned to the custodian or museum.

11

5.5

Recording of Features and Deposits

Any in situ pre-1900 or significant 20th century archaeological deposits or features exposed during clearance works will be investigated, recorded and sampled consistent with accepted archaeological practice as set out in this DWP and in accordance with the requirements of the HNZPT Authority (no.

2017/793). Detailed notes of each feature and deposit will be made, photographs will be taken, and all subsurface features located will be detailed on the site plan. Stratigraphic drawings and photographs of features and deposits will be undertaken.

Sufficient time and opportunity will be allowed for the recording and sampling of any archaeological features or deposits encountered. The archaeologist(s) will record the archaeological feature(s) or deposit(s) as quickly as possible so that works may resume without undue delay.

However, if the feature is deep or extensive, and can be safely covered and protected in situ, investigation may be deferred to the main works stage.

5.6

Artefact Management Plan

The locations of artefact deposits will be marked on the site plan and retained for analysis. If large numbers of artefacts relating to European occupation are exposed, a representative sample will be retained.

The process for storage, analysis and display shall be as follows: •

Artefacts will be bagged, labelled by date and context, and may initially be stored in a secure on-site lock-up facility provided by the contractor;

•

As soon as is feasible artefacts will be transferred to the Project Archaeologist’s offices for cleaning, recording and analysis;

•

Any significant artefacts and/or artefacts meriting public display, will be identified by the Project Archaeologist and, in consultation with the relevant stakeholders, will be considered either for display within the new Karangahape Road Station or for donation to the Auckland War Memorial Museum, as appropriate;

•

Less significant finds will be disposed of following recording and analysis, subject to CRLL agreement, unless a museum is willing to accept the collection; and

•

Any wooden or fibre artefacts of significance will be wrapped/contained as required for short term preservation and analysis.

Artefacts will be conserved by appropriate specialists if this is recommended by the Project Archaeologist based on the level of significance and suitability for display or addition to museum collections.

Any Māori artefacts that meet the criteria of taonga tūturu under the Protected Objects Act 1975 will in addition be managed as set out under the Mana Whenua Protocols (Section 5.4 of this DWP).

5.7

Stand Down Periods

Depending on what is revealed by the clearance works, stand down periods involving the ceasing of works in the immediate vicinity may be required at various stages to allow for archaeological work to be carried out or for consultation with the appropriate parties.

Stand down will require clearance works to cease only in the immediate vicinity of the feature or find, and work may proceed in other areas. The maximum stand down periods in Table 5.1 will apply but works may be resumed earlier if the required work has been completed.

12 Timeframes need to be flexible enough to ensure that archaeological works are completed as necessary to ensure that the conditions of the Archaeological Authority (no. 2017/793) are met.

Table 5.1:

Work resumes when the Project Archaeologist or HNZPT advises the site foreman that work is completed

Post Excavation Analysis and Archiving

Artefacts and faunal material retained from the site will be analysed and recorded by the appropriate specialists with the results presented in the final archaeological report, which will be provided to the parties specified in Section 5.9 of this DWP for information and archiving.

13 Depending on what is exposed, consideration will be given to displaying archaeological material such as artefacts within the new Karangahape Road Station.

Any artefacts of significance relating to European occupation of the area that are recovered from the site that are not required for display may be offered to the Auckland Museum in consultation with CRLL. Any Māori artefacts (taonga tūturu) will be dealt with in accordance with the Mana Whenua protocols outlined in Section 5.4 of this DWP and the requirements of the Protected Objects Act 1975.

Archaeological material identified by the Project Archaeologist as being appropriate for Carbon 14 dating will be sent to the University of Waikato’s Radiocarbon Dating Laboratory for age determination.

5.9

Reporting Requirements

During the course of the project, information on any archaeological discoveries will be provided to the Auckland Council Cultural Heritage Implementation Team and Consent Monitoring Officer, HNZPT and Mana Whenua.

Opportunities for provision of information to the public via on site and media releases will be taken in consultation with those parties, depending on whether any significant archaeology is exposed during earthworks.

In compliance with the requirements of HNZPT Authority 2017/793, a written summary report will be provided by the Project Archaeologist to CRLL, HNZPT, Auckland Council (Cultural Heritage Implementation Team and Consent Monitoring officer) and Mana Whenua within 20 days of the completion of the project works. A full and final monitoring report will be completed within 12 months of the end of the project works, and will be provided to CRLL, HNZPT, the Auckland Council (for inclusion in the Cultural Heritage Inventory), the NZ Archaeological Association Central File, Mana Whenua and any other parties specified in the designation conditions and archaeological Authority. On completion of the final report, the Project Archaeologist will update the archaeological site records on the NZAA Site Recording Scheme (ArchSite database) and Auckland Council Cultural Heritage Inventory with a summary of the results and reference to the final report.

Depending on the significance of the archaeological information recovered, articles may be submitted to academic journals for publication.

The process for updating this DWP as a result of a material change to the Project or the annual review is outlined in CRL designation condition 23 and section 5.7 of the CEMP. An original copy of this DWP document and subsequent versions will be kept for the Project records (earlier versions marked as obsolete). Each new / updated version of the Archaeology Section of the Historic Character DWP documentation will be issued with a version number and date to eliminate obsolete versions of this DWP documentation being used, and will be kept on site during works.

A summary of the review process will be provided to Auckland Council and otherwise be made available on request.

CRLL is seeking ISCA (infrastructure Sustainability Council of Australia) IS (infrastructure Sustainability) Rating for the whole project lifecycle where the requirements as per ISCA CRL IS Technical Manual – Mahi Rauora Aratohu - Version 1.2 are essential to achieve the Project’s sustainability goal (Reference to CRLL minimum requirements - Appendices 10, 23 and 24 of the contract documents). The IS rating requirements that relate directly to this Historic Character DWP are included in Appendix C. which need to be reviewed, amended (as and if needed) and confirmed as the project proceeds and prior to commencing works to meet the target levels set for the project and agreed on with ISCA and CRLL.

Appendix A:

HNZPTA Authority Requirements

In addition to the requirements of the CRL designation, and this DWP prepared in accordance with CRL designation condition 42, all modification and investigation of pre-1900 archaeological remains are subject to the archaeological provisions of the Heritage New Zealand Pouhere Taonga Act 2014 (HNZPTA) and must be carried out in accordance with the conditions of an Authority issued by HNZPT under that Act. A general Authority for the Aotea Station to Mt Eden Station/NAL works, including modification of any subsurface remains at the Karangahape Station CSA, has been granted by HNZPT (Authority No. 2017/793). The Authority sets management procedures in place for archaeological discoveries.

Care has been taken to ensure that the archaeological procedures set out in this DWP are consistent with the conditions and requirements of the Authority issued by HNZPT.

Resolution

Table 1.1, and throughout Some of the references to other parts of the document, e.g., to Section 5.8 in Row 5, appear to be incorrect.

Please check all cross references in the DWP and amend if required.

Table 1.1 checked and some amendments made

Archaeological sites in the project area refers to early 20th century, or significant 20th century historic heritage (also Section 5). It isn’t clear how this significance is to be determined or how (Section 5.3) the Auckland Council Cultural Heritage Implementation Team Leader will direct that such archaeology be investigated and recorded.

No change. Significance would be determined by the project archaeologist in consultation with the Auckland Council Cultural Heritage Implementation Team Leader.

The qualifying term ‘significant’ is necessary as there may be a considerable amount of 20th century archaeological remains (infrastructure etc) that do not merit archaeological recording. Note that the HNZPTA 2014 uses similar terminology in s.43, which provides for a post-1900 site to be declared to be an archaeological site if it “provides, or may be able to provide, significant evidence relating to the historical and cultural heritage of New Zealand”. “Significant evidence” is not defined in the Act.

It should be noted that authority 2017/793 applies to the construction phase of the CRL as well as the demolition phase, and for the entirety of the project, not just Karangahape Station.

Section 2.1 refers to Appendix A, which describes the scope of the Authority 2017/793 as covering all works, and includes the Authority itself

3.1

Project Archaeologist roles and responsibilities states the Project Archaeologist will ensure “that the archaeological team adheres to the contractor’s site safety requirements.” Please check whether the contractor’s safety requirement of CRLL’s have precedence and amend if required.

No change. The contractor’s site safety requirements apply to anyone entering the site.

Table 3.1

Contact details lists Isaac McIvor as HNZPT archaeologist. He has now left HNZPT, please amend (also in the Mt Eden DWP).

Contact list amended

5.1

9A-21 Mercury Lane states that “an archaeologist will be present during final demolition of the buildings and site clearance”, while 5.2 Archaeological Discovery Protocols states that “the possibility that archaeological features and deposits may be exposed during site clearance works will be managed and mitigated by call-in by the contractor.” These two statements are contradictory. If 5.1 applies only to 9A-21 Mercury Lane and 5.2 applies only to other properties, make this clear.

The word ‘elsewhere’ has been added to sentence 1 of 5.2 to clarify that this applies to other properties

5.4.3

Taonga, bullet point 3, “stand down period specified above” should be “specified below.”

Amended

5.6

Artefact Management Plan presumably applies only to artefacts that are not taonga tūturu covered in 5.4.3. Make this explicit. Make it clear that some artefacts of Māori origin, such as stone flakes, are not taonga tūturu.

This section relates to the recording and analysis of all artefacts, whether Maori or European, though Maori artefacts would not be expected. However, for clarification the last sentence has been amended to read: “Any Māori artefacts that meet the criteria of taonga tūturu

under the Protected Objects Act 1975 will in addition be

managed as set out under the Mana Whenua Protocols (Section 5.4 of this DWP).” (Italics indicate the changes made)

5.7

Stand Down Periods This section states that “timeframes need to be flexible” and section 5.6 states that “sufficient time and opportunity will be allowed for the recording and sampling of any archaeological features or deposits encountered.” However, Table 5.1 provides for Maximum Stand Down Periods, which is incompatible with flexible timeframes and sufficient time and opportunity, as well as Condition 3 of HNZPT authority2017/793 which states that “All archaeological evidence encountered during the exercise of this authority must be investigated, recorded and analysed in accordance with current archaeological practice.” Current archaeological practice is potentially time consuming and, while it is understood that the archaeologist will make very reasonable effort to clear the area a quickly as possible, this may not always be possible within the time frames outlined on Table 5.1. This table also states “Note that there may be special circumstances in which a longer period of stand down for investigation is deemed necessary by either HNZPT or Auckland Council.” This is potentially confusing.

I suggest that Table 5.1 be changed to Stand Down Triggers, the second column deleted and the table re-formatted to include relevant

No changes have been made, as the contents of this table are consistent with the Archaeological Management Plan approved under the Heritage NZ Authority (2017/793) and have been standard for previous Authorities and Heritage Management Plans approved by Council for other projects.

We do not consider there is incompatibility between the fact that contractor’s timeframes need to be flexible, and the minimum stand down periods given, as the necessary flexibility sits within those timeframes. Limited if any remains are likely to be encountered during site clearance and a slightly longer stand down period is given for any significant archaeological remains encountered, with appropriate recognition that HNZPT or Council may require a longer period for investigating any significant discoveries. In addition, there is always the option of deferring investigations until the main works stage, if necessary.

HNZPT, Council and mana whenua response times.

5.8

Post Excavation Analysis and Archiving appears to apply only to artefacts but should include midden / faunal remains and any other archaeological material that may be excavated.

The words ‘and faunal material’ have been added to the first sentence after ‘artefacts’, for clarification

5.9

Reporting Requirements are in compliance with the HNZPT authority. This should be made clear.

“In compliance with the requirements of HNZPT Authority 2017/793” has been added to the start of paragraph 3 of this section

APPENDIX C: ISCA Requirements CRLL is seeking ISCA (infrastructure Sustainability Council of Australia) IS (infrastructure Sustainability) Rating for the whole project lifecycle where the requirements as per ISCA CRL IS Technical Manual – Mahi Rauora Aratohu - Version 1.2 are essential to achieve the Project’s sustainability goal (Reference to CRLL minimum requirements - Appendices 10, 23 and 24 of the contract documents). This Appendix includes IS requirements that are necessary to achieve a target level 2 of Her-1 and Her-2 ISCA credits. These requirements remain subject to change as the project goes forward. Hence, the below Table to be reviewed, amended (as and if needed) and confirmed to meet the target level that will be set and agreed upon.
