In our previous article we provided an overview of the draft National Planning Standards where we accepted that the principle of standardisation had merit but raised concerns about the practicalities of implementing a one sized fits all approach.

That view was shared by many submitters during the consultation period with a total of 201 submissions made on the draft standards (57 submissions were made by local authorities and 70 by business/industry).  Of those submissions, two-thirds reportedly expressed support in principle or in part for the planning standards, however almost all submissions requested changes.

The resultant changes are significant and we think they will provide real assistance in implementation.  Some challenges will of course remain as is to be expected in a procedural shift of this nature but overall we are hopeful the advantages of standardisation will outweigh the teething pains.  Of course with implementation over an extended period, it will be some considerable time before a judgement on that matter can be made.

To appreciate what has happened and where this will lead, it’s helpful to first understand the legal and engineering framework within which seismic assessments of buildings are made. The starting point here is the guidelines for The Seismic Assessment of Existing Buildings (Guidelines), which detail the technical basis on which engineers carry out seismic assessments of existing buildings. In basic terms, the Guidelines govern how seismic engineers review a building to arrive at a robust assessment of its “%NBS” – the all important percentage of the “new building standard” that an existing building achieves.

This process and the outcomes are hugely important because a %NBS rating (almost universally misunderstood by property advisors and lawyers alike) has become a proxy for seismic safety. As a result, %NBS underpins acquisition, development and leasing decisions and is a key consideration for many Crown agencies and corporates in their property strategies and health and safety assessments. The Guidelines also form part of the EPB (earthquake prone building) methodology produced by the Ministry of Business, Innovation and Employment, by which territorial authorities are required to identify earthquake-prone buildings.

When version 1 of the Guidelines was first released in July 2017 (superseding guidance from 2006), it was seen as a significant step forward. The Guidelines were an extensive revision by industry experts of earlier thinking and incorporated a wealth of research, knowledge and experience obtained from the significant New Zealand earthquakes between 2010 and 2016 – a period which included the Christchurch, Seddon and Kaikoura earthquakes. As such, and with one critical exception, the Guidelines represented the latest understandings on the seismic behaviour of existing buildings.

That one critical exception was Section C5 of the Guidelines, a section governing the detailed seismic assessments of concrete buildings. With the timing of the general release of the Guidelines in mid-2017, it simply wasn’t possible to include new guidance on a range of matters, including assessing precast concrete floor systems to take account of new knowledge from the Kaikoura earthquake, and to respond to recommendations made in the Statistics House investigation. However, this was remedied in November 2018 with the release of a new Section C5 (version 1A), and the slow slip quake in the market began.

The revisions to Section C5 are numerous, with changes addressing: material strength, “single crack” scenarios in concrete members, deformation limits due to buckling of walls and columns, limiting conditions leading to the loss of gravity support in columns, slab-column connections and walls, and strength degradation for lightly reinforced joints. None of that appears particularly reassuring to the untrained eye but, more significantly, there is also a complete revision of the guidance detailing the assessment of precast concrete floors – that is, precast concrete hollow-core, double-tee, rib and infill, and flat slab floor units, all of which have been relatively common methods of floor construction since the 1980s.

In relation to precast floors, the new Appendix C5E records in unemotive engineering prose that, in an earthquake, it is possible for “unseating” of precast floors to occur (that is, precast floors may fall off their supporting ledges within the building frame) and that precast floors can be particularly susceptible to damage that has the effect of “compromising gravity load support” (that is, precast floors may collapse). Appendix C5E goes on to state that “For buildings with older support detailing, the limiting drift at failure of the precast floors is likely to be less than the limiting drift for the frame and may govern the earthquake rating for the building as a whole.” Translated, this means that precast floors may fail before the building frame itself and, if that is the case for your building, then its %NBS will diminish to that earlier point of failure.

While the devil is very much in the engineering detail, the practical effect of the changes to Section C5 of the Guidelines is that the %NBS of many relatively new buildings with precast floors is likely to fall. There are many such buildings in New Zealand but, of the larger centres, Wellington, Napier, Hastings and Palmerston North are likely to be disproportionately affected due to their higher “Z-values”, being the seismic risk factors applicable to those regions.

How much lower the %NBS numbers will go is, of course, a key issue, as is whether buildings remain safe. These assessments in turn depend on a range of factors relating to a particular building, including the type of floor and the flexibility of the building frame. You will need an engineer to tell you but, for some buildings, the %NBS drop may be significant. While it hasn’t been highlighted in reporting to date, Aurecon New Zealand Limited’s assessment of Wellington Central Library, is “that the hollowcore precast floor system… achieves a score of 20%NBS” – this for a building that opened in 1991.

Of course, not all buildings will be affected like Wellington Central Library and, for some buildings, a small %NBS decrease may not be material.  However, for owners, tenants, funders and insurers of a 70%NBS structure, a 15-20% drop may well have major ramifications. Where a change in %NBS crosses a critical threshold for a party, their options will, as ever, be constrained by their existing contracts and the availability of alternatives.

Weaknesses in leasing documents will also be exposed. The standard ADLS deed of lease, for example, does not address seismic standards and a number of leases with negotiated seismic covenants require there to be an earthquake of a minimum magnitude before the tenant can even access rights related to the %NBS of the building. Neither position is advisable. However, even where a tenant has a contractual escape route, its options will be practically limited by the availability of alternative premises and business continuity requirements.

A further issue is how or whether affected parties will even know that the %NBS of the building has fallen. In the absence of an earthquake, few tenants will have cause to consider the accuracy of historical seismic reports. The statutory framework also provides little comfort; while territorial authorities are tasked with identifying potentially earthquake prone buildings, these are only buildings below 34%NBS and, even then, for at least an interim period of 18-24 months, those “EPB” assessments must continue to be made using the old Section C5 of the Guidelines. This means that for earthquake prone building purposes there may well be “false negatives” – i.e. %NBS ratings above those supported by the latest engineering knowledge. Beyond the earthquake prone building framework, there is generally no incentive or legal requirement for landlords to seek assessments that may indicate things have changed for the worse, or to disclose these if they are obtained.

Even less likely is that owners, outside local or central government, will close their buildings and, other than in the most extreme cases, there is no legal requirement for them to do so. In the case of Wellington Central Library, where engineers identified that “the potential loss of seating of the hollowcore units presents a significant hazard and potential risk to building occupants following a significant earthquake event”. Mayor Justin Lester observed that "We're not legally obliged to close this building, we are morally obliged”. Not all building owners will see it the same way.

Those concerned about their buildings should seek information from engineers and owners and take engineering and, potentially, legal advice. Next steps can then be informed by reference to assessed risk, existing contractual positions and organisational health and safety policies and obligations.

Some philosophical issues to sort out with an Urban Development Authority model based on our experiences in Christchurch.  If coming to the end of the use of such powers in Christchurch is seen as a “return to local leadership” does it follow that the use of such powers in the first place is an affront to local democracy?  And how does that fit with the intention to deliver national UDA legislation.  Good conversation starter.  Want to know more, please do not hesitate to contact Lauren Semple or our Resource Management team.

It first looks at a number of the alternative legislative schemes set up in recent years to fast track development (including subdivision), and considers some of the lessons from these examples which may usefully inform future legislation including the much touted but not yet here urban development authority approach.  It touches on the role of, and tools available to, local authorities under the Local Government Act in relation to subdivisions, including the use of development contributions and development agreements to service growth and asks whether our preoccupation with new tools might prevent us from effectively utilising the tools we already have.

The Draft Plan was released for consultation on 14 November 2018 with submissions due by 5pm on 19 December 2018.  You can find a copy of the draft plan here - http://engage.regeneratechristchurch.nz/accessible-draft-oarc-regeneration-plan-homepage
 

Wellington Partner, Doran Wyatt had the honour of presenting the Greenwood Roche Supreme Award as part of the event on 11 October 2018.

Congratulations to McKee Fehl Constructors Ltd, this year’s winner of the Greenwood Roche Supreme Award, for the Press Hall 80 Willis Street / 22 Boulcott Street project.
 
What stood out for the judges was the ability of McKee Fehl to repurpose and modernise the Press Hall site.  The end result is an iconic development that adds vibrancy to Wellington but also respects the heritage of the original building.
 
The testimonials for this project summed it up:

• “The concept of unlocking Press Hall, which was essentially buried in between Boulcott Street and Willis Street, was a clever idea.”
• “The newly formed urban laneway leading to the food hall is activated by vibrant and diverse kiosks and a bar above, the veranda can now be occupied by people adding to the urban fabric of the street.”
• “Never before have such old, run down, dark and dingy buildings been so substantially structurally modified, seismically upgraded and refurbished to create such an open, vibrant and modern workplace.”

Eligible urban development projects will include the provision of new public, affordable and Kiwibuild housing, as well as transport links, commercial and industrial developments, infrastructure and supporting community facilities (schools, pools, open spaces and libraries). The HUDA will also absorb the function of Housing New Zealand as the landlord for public housing in New Zealand.

In the main, the Act is not intended to change our land transfer laws substantially. However, some controversy exists regarding the right of an owner to reclaim title under the manifest injustice provisions, arguably eroding the principle of indefeasibility of title. Also, not all changes promoted during consultation have been adopted, such as placing more onus on mortgagees to verify the identify of their clients, separately defining encumbrances from mortgages, and permitting senior legal executives to certify and sign instruments in Landonline.
 
Some key changes are set out below.
 
New terminology
The Act includes new terminology aimed at modernising the language used. For example, a “certificate of title” and the clumsy “computer freehold/leasehold/interest register” has become the crisper “record of title”, and “registered proprietor” has become “registered owner”. There is also a concept of “replacement lease”, which is a renewed lease or a new lease in substitution for a prior lease between the same parties and relating to the same land.
 
Withholding information for a person’s safety
The Registrar-General of Land is able to refuse to provide a copy of an instrument or a record of title that identifies a person, or to include those details on the register in the first place, if the Register is satisfied that the information discloses or is likely to disclose the person’s location and prejudice their safety.
 
Caveats
There is now an express right for an owner of an estate or interest in land to lodge a caveat against their own title where there is a real risk of fraud.
 
Guaranteed title searches
Guaranteed searches back up the security of the land transfer system, by providing a right to compensation if a purchaser of an interest in a land transaction suffers loss due to the registration of a competing interest. Under the Old Act, the purchaser had to obtain a “guaranteed search” within 14 days before settling the transaction, and had to lodge the transaction documents within 2 months after settlement.
 
The Act updates these periods to reflect the electronic nature of land transactions by:

• requiring that a guaranteed search of the title be obtained within 5 working days before (and including) the settlement date; and
• reducing the period after settlement during which the transaction documents must be lodged at Land Information New Zealand (LINZ) to 20 working days.  

• altering the description of the affected land from “servient tenement” to “burdened land” and from “dominant tenement” to “benefited land”;
• referring to the part of the burdened land subject to the easement as the “easement area”, in line with commonly-used wording;
• updating and aligning the equipment that can be installed under the various types of easement;
• removing unnecessary wording, such as replacing the class of easement previously called “telecommunications and computer media” with simply “telecommunications”;
• requiring the owner of the burdened land to act reasonably when the grantee seeks to install easement facilities; and
• adding an implied electricity conveyance right in order to operate equipment installed under the easement powers (eg. a water pump).
