Technical Report to support Assessment of Environmental Effects (City Rail Link Notice of Requirement): Built Heritage Assessment

APPENDIX A Built Heritage potentially affected by Vibration and Settlement

CRL / Built Heritage Technical Expert Report /Appendix A

Possible Vibration and Settlement Effects on Built Heritage The following is a list of Historic places that have been identified by Aurecon Structural Engineering as likely to be affected by the construction of the CRL in a slight or moderate way, using the building damage classification defined in table 7.2.1 of the Structural Engineer Technical Expert Report (below).

This list is an edited version of an initial list of Historic Places that were identified as being located within 100 metres either side of the indicative centre-line of the proposed CRL route.

All lists should remain key references until the specific construction methodology for the CRL is confirmed.

Initial analysis identified 254 properties which, with the successive refinement to the limits of the vibration and settlement contours, have reduced to approximately 118 potentially affected properties (ref. Appendix E), of which around 50% are formally recognised historic places either as registered by HPT or scheduled by Auckland Council or noted on the CHI. Of these, just 55 properties have been found to be possibly affected; 20 being “slightmoderate”, the remainder having potentially “slight” risk. (ref. below) The nature of historic places could mean that even the slightest damage may have significant effect on their heritage value. We have therefore taken the conservative approach of including these for further detailed assessment during the subsequent stages.

Very Slight

Fine cracks easily treated during normal redecoration.

Perhaps isolated slight fracture in building. Cracks in exterior visible upon close inspection.

Slight

Cracks easily filled. Redecoration probably required.

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

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

Utility services may be interrupted. Weather tightness often impaired

4

Severe

Extensive repair involving removal and replacement of walls especially over door and windows required.

Window and door frames distorted. Floor slopes noticeably. Walls lean or bulge noticeably. Some loss of bearing in beams. Utility services disrupted.

5

Very Severe

Major repair required involving partial or complete reconstruction. Beams lose bearing walls lean badly and required shoring. Windows broken by distortion.

Danger of instability.

Aesthetic Damage

Serviceability Damage

Stability Damage

Summary: Description

Properties Identified

Built Heritage in Study Area Broad analysis included within the initial site area - 200m corridor (100m either side of the indicative centre line of the CRL (ref 2.4)

238 properties identified within the initial study area (ref Appendix C & D)

Built Heritage within Vibration and Settlement Corridors 110 properties within With the successive refinement to the limits of the vibration and settlement vibration and settlement contours (ref Appendix B) contours Potential Affected Heritage Properties Formally recognised historic places either as registered by HPT or scheduled by Auckland Council or noted on the CHI. The remainder have been categorised depending on whether they are seen as Potentially Historic, ‘Character Defining’ or ‘Character Supporting’ by site survey and desk top analysis.

Around 53 of these are identified in the Built Heritage Technical Report as having recognised heritage value. (below)

We have categorised the buildings and structures that fall within the area of this study into three classes: Type A: are those buildings, structures and areas that are identified in statutory lists such as the former Auckland City Council “Schedule of buildings, heritage properties, places, monuments and objects of special value and those subject to heritage orders”, the Historic Places Trust Register and the former Auckland Regional Council Cultural Heritage Inventory.

Type B: are those buildings, structures and areas that are not included in formal lists, but that are seen as having heritage significance or making an important contribution to the built environment and its character. These buildings and structures are seen, therefore, as being ‘character defining’.

Type C: are those buildings and structures that are seen as being ‘character supporting’ and form part of a group of significance as well as having some individual significance, but are not currently protected by statutory mechanisms.

Of the 55 properties identified as being potentially affected there are; Slight - Moderate Affected Properties Cracks may require cutting out and patching. Recurrent cracks can be masked by suitable linings. Brick pointing and possible replacement of a small amount of exterior brickwork may be required. Doors and windows sticking.

Utility services may be interrupted. Weather tightness often impaired

20 Properties in the slight to moderate category. Of these 20 there are; 4 Type A 15 Type B 1 Type C Total 20 properties

Slightly Affected Properties Cracks easily filled. Redecoration probably required. Several slight fractures inside building. Exterior cracks visible, some repainting may be required for weather-tightness. Doors and windows may stick slightly.

40 Properties in the slightly affected category.

Of these 40 there are: 13 Type A 20 Type B 2 Type C Total 35 properties

Limitations of Schedule While every effort has been made to ensure individual buildings and structures are accurately described as to extent and heritage classification the map is illustrative only and the location of buildings and structures is indicative only. Difficulties were encountered reconciling GIS street addresses with individual heritage classifications and building outlines shown on aerial photographs. Some of the properties are individually owned or on separate land parcels but form part of a larger building. An effort has been made to recognize this but there will need to be further specific structural analysis completed at a second stage our identification work with actual building construction.
