Documentation regarding the role the use of juvenile pinus radiata wood for structural purposes played in the leaky building crisis

Edward Grove made this Official Information request to New Zealand Forest Research Institute Limited

This request has an unknown status. We're waiting for Edward Grove to read recent responses and update the status.

From: Edward Grove

Dear New Zealand Forest Research Institute Limited,

Hi, I wish to request copies of any reports, correspondence or documentation from 1992 to 2005 which discusses the extent to which the use of structural lumber containing substantial amounts of "Juvenile" (aka "Core") wood from pinus radiata (i.e. from the second rotation or production thinnings) may have, or did, contribute to causing the building failures and/or weather-tightness issues which have come to be colloquially referred to as the "leaky building crisis". In particular, I am interested in any discussion regarding to the actual or potential consequences of longitudinal shrinkage of such material when used in residential structural or cladding applications.

Yours faithfully,

Edward Grove

Dear Edward

 

Further to your OIA requests to Scion, we propose amendments to the
requests to clarify meaning and ensure consistency between the requests.

 

You have referred to construction failures and building failures with
particular reference to weather-tightness.  We have proposed amendments to
your requests to clarify a failure is after building completion (compared
to failures during construction) that has an adverse impact on the
structural integrity of the building, which may or may not have an impact
upon weathertightness.  Weathertightness issues can be caused by many
factors and a failure of structural integrity may be one of those or not,
and likewise a failure of structural integrity may or may not cause
weathertightness issues.

 

You have referred to causal link between properties of Pinus radiata
juvenile / core wood and building failure, and also to the use of Pinus
radiata juvenile / core wood contribution to cause building failure.  We
have proposed amendments to clarify reference to a causal link between the
properties of Pinus radiata juvenile / core wood and the building failure
in each request. 

 

These amendments are consistent with your interest area and help us
clearly identify the relevant information across each request. 

 

Your original request and the amended request is set out below.

Dear Edward

 

Thanks for your emails.  For ease this email relates to all your requests.

 

Your comments were very useful, and I’ve further revised the requests as
highlighted below. 

 

Your clarification regarding potential or actual causal link has been
added and reflects what we understood the request referred to.  

 

Your clarification regarding longevity and performance has also been
added.  We have linked longevity to the Building Code to give some
objective reference point.  We have mentioned structural integrity as
being part of performance but we understand your interest is wider than
this.  The Building Code provides some guidance regarding performance but
we have not expressly mentioned this as we understand your interest is
wider than this.

 

Your clarification regarding residential buildings was useful and I have
expressly mentioned this in the revised requests.    

 

Looking at the requests, I wonder if the request from Tuesday 30 June
covers the same information, but for a shorter time period, as the second
part of the request from Thursday 2 July.  Are you content that we
disregard the Tuesday 30 June request?  If you consider the Tuesday 30
June request to be distinct from the second part of the Thursday 2 July
request, could you please provide further information on the difference
between the two requests?   

 

Please note the amendment of a request is considered to a new request for
the purpose of calculating the maximum statutory timeframe for response
(see section 15(1AA) of the OIA).  Today is seven working days from the
date of the original Thursday 2 July request and so we will calculate our
time to respond from today’s date.  Accordingly our new date to respond
(being 20 working days from today) is 10 August 2020.    

 

We will search our records for the relevant information based on the
revised requests from Thursday 2 July.

 

We have not started a search of our records yet and from my initial
discussions with our scientists it appears that most of our work has
looked at the properties of juvenile / core Pinus radiata without
necessarily linking those properties to building failure.  Any building
failure work appears to mainly relate to the building failure of
structural building elements within the narrower definition of structural,
that is we have limited/no work related to cladding, flashing or roofing
elements.  Likewise, Scion has looked at building failure where
weathertightness may have also occurred, but Scion has not looked at
weathertightness as a singular issue.  You are probably aware that BRANZ
has carried out more work than Scion in the area of building failure and
weathertightness, and that MBIE’s building performance group is active in
this area. 

 

We will be in contact but please do not hesitate to contact us if you have
any queries. 

 

For your information I am on holiday for the rest of this week; back in
the office on Monday 20 July.  My colleague John Eley (copied above) will
be able to assist in my absence.

Subject: RE: Official Information request - Directives issued to, or by,
NZFRI restricting mention of Juvenile Wood in relation to Building
Failures

 

Dear Lynda Frew,

The proposed amendment looks largely fine. I would like to clarify
however,

(a) where the proposed amendment refers to "any causal link", I am
interested in documentation regarding not only actual proven or accepted
causal lins, but also any identification/speculation by Scion and/or its
employees regarding potential causal links. i.e. so that the amendment
refers to "any actual or potential causal link" By way of example D J Cown
had in his 1992 article for Scion "Corewood (Juvenile Wood) in Pinus
Radiata - Should we be Concerned?" - written before (I understand) the
leaky building crisis emerged, identified that the wood properties of the
second-rotation juvenile wood that was already in use in New Zealand "may
be sufficiently different to cause manufacturing difficulties and
properties in service", that juvenile wood had overseas "been blamed for
excessive movement" , that new crop density was "at the lower acceptable
limit" for structural use, and that "it is not conceivable that large
trees harvested at say 20 years will have desirable properties for most
solid wood uses". Strictly speaking that article might be described as
containing only speculation as to the possibility for juvenile/core wood
to cause construction failures, but nonetheless I am interested in such
informed-speculation by Scion on the subject. So, I would like to ensure
all such documentation which is in the nature of speculation of possible
causal links, and not just documentation which records confirmed causal
links, be included in any response.

(b) where the proposed amendment refers to "structural integrity", I wish
to clarify that I do wish the request to extend to matters such as
failures of claddings, exterior paint surfaces/barriers, flashings and the
like. There seems to be a lack of consistency in the (New Zealand)
scientific and industry reports as to whether cladding for example is
regarded as a "structural" element. It clearly was in the 60s, but
certainly since the 80s most of the scientific/industry discussion appears
to describe cladding and flashing elements as non-structural, - at least
in the context of any discussion of residential construction. In short, if
it is a building element, and its failure could materially impact on the
performance/longevity of a residential construction, and Scion has
identified an actual or potential causative link between that failure and
the properties of junvile/core wood in Pinus radiata, I would like to
receive copies of all such documents discussion same. By way of example, I
understand that in 2010/11 Scion advised the New Zealand Metal Roofing
Manufacturers Association Inc regarding potential causes of roof flashings
buckling, and identified the problem as being due to the occasional
presence of compression wood, and in particular the "vastly different
[longitudinal] shrinkage characteristics of such wood". That shrinkage was
stated as being between 0.4 - 1% for compression wood. Scion's advice to
the New Zealand Metal Roofing Manufacturers Association Inc is recorded in
the New Zealand Metal Roofing Manufacturers Association In's publication
to its members as having been that while juvenile wood was also "becoming
common", and juvenile wood would also shrink longitudinally, it would "not
[shrink] as much as compression wood". Scion's own published research now
records that juvenile radiata wood has even greater average longitudinal
shrinkage than the 0.4-1% advised for compression wood, and the vast
majority of light framing timber available in New Zealand demonstrably (by
visual examination of ring width and curvature) consists of predominantly
juvenile wood (and indeed much includes the pith). Hence it is reasonable
to expect that at some point within Scion, before or after advising the
New Zealand Metal Roofing Manufacturers Association Inc regarding the
possibility of the occasional presence of compression wood to cause roof
flashings to buckle, there will have been consideration and discussion of
the far more common juvenile wood, with even greater longitudinal
shrinkage, to cause even more severe buckling. Documents embodying
discussions of such actual or potential problems are exactly what I am
after, regardless of whether the failure of such roof flashings do or do
not fall strictly within any particular definition of a "structural
failure".

Thanks for your assistance

New Zealand Metal Roofing Manufacturers Association Inc regarding the
possibility of the occasional presence of compression wood to cause roof
flashings to buckle, there will have been consideration and discussion of
the far more common juvenile wood, with even greater longitudinal
shrinkage, to cause even more severe buckling. Documents embodying
discussions of such actual or potential problems are exactly what I am
after, regardless of whether the failure of such roof flashings do or do
not fall strictly within any particular definition of a "structural
failure".

Thanks for your assistance

Dear Lynda Frew,
The only real distinction I see between the 30 June request and second part of the 2 July request is that the 30 June request will also include purely internal documentation and documentation received by NZFR, whereas the second part of the 2 July request covers advice/communications outwards from the NZFR to third parties.

Just by way of an addendum, and perhaps explanation: I've recently been advised by a cladding manufacturer that the house my insurers has proposed building (a house-fire rebuild) would, as designed, have all of its radiata cladding (the manufacturer's own cladding) critically fail at every corner in under a year, despite meeting the building code and being constructed in accordance with the original construction details, and would not have been under warranty. i.e. the house would have simply unzipped at the seams, and I would have been financially wiped out if the house had been constructed substituting radiata for the original cladding wood. The cause of the failure was that the proposed new cladding (radiata) was insufficiently stable to be mitre-jointed at the corners without external soakers as per the original construction detailing. That prompted some research, only for me to discover that radiata was (treated or not) illegal to use for exterior cladding in most districts (including Auckland) through most of the ear;u 1960s when the original house was constructed, and was expressly not-recommended by the NZFR at that time for any exterior use at all, treated or not, due to its instability and permeability, and that the second rotation crop in use from the late 1980s onwards had a known higher-instability. Per Cown, - the second rotation's woods physical qualities were so deficient it needed to be treated as a "different species" and new utilisation methods would have to be developed, per Burdon, the reduced physical properties of second rotation radiata had been a "nasty surprise"). That obviously led to the issue of what role the dimensional instability (and reduced cell wall thickness, greater lumen size, micofibril angle, reduced polysacharide content, reduced response to conventional preservatives, and greater permeability due to the increased use of kiln-drying and consequent effect on resin ducts) played in the monolithic cladding failures. Particularly given the long (50+) year history in New Zealand of relatively problem free use of monolithic cladding prior to the late 1980s, and also given the historic importance placed within the building industry on the stability of framing when installing monolithic cladding. Yet there did/does not seem to be any public mention at all in New Zealand of the second rotation/juvenile wood as being a potential contributing cause of the building failures that started at the end of the 1980s. That seemed odd, researchers overseas were even in the 1980s describing the prospect of using juvenile wood in residential construction as an "apocalyptic" scenario, and throughout the early 1980s there had been repeated warnings by New Zealand scientists (including Cown) that the second rotation radiata might not be able to be used successfully in construction. In short, in the public information, there seems a very conspicuous blind-spot at least since the early 1990s onwards in which any mention or consideration of the fact that the second-crop radiata properties were so massively worse might have caused some of the novel building failures that were emerging. Yet, conversely, there have since the early 1990s been a significant number of building changes which seem expressly designed to work-around the issues of juvenile wood, but without identifying the presence of juvenile wood as being the reason why such changes were required. Lvl would be an example. Mandatory use of expansion joints where previously not required, and so on. What is also odd is that even from as early as 1989 there were multiple disparate industry participants, - wood processors, builders, BRANZ, flashing and plasterboard manufacturers that I've seen, who have raised or discussed with their members and the industry experiences they were having of abnormal wood movement, and resulting construction failures, all very obviously groping for an answer as to why they were experiencing problems, but obviously also not receiving answers, when the reasons were identified as a hypothetical in the late 1970s, and largely confirmed by the NZFR's research in the 1990s. So, I'm wondering why there is an apparent blindspot, and disconnnect, between known problems with the short rotation radiata (at least, problems with the majority of the wood from such radiata), and the building failures that continue.
If anything is going to shed light on it, as I see it it will be the NZFR's documentation.

Yours sincerely,

Edward Grove

Dear New Zealand Forest Research Institute Limited,

Hi Lydia,

I just have one issue with the proposed amendment, - the express linking of longevity to the Building Code.

The 1992 Building Code did substantially reduce acceptable longevity standards for a number of wood components.

For example the 15 year longevity requirement for wood cladding at a ballpark equates to a less than 5 year in-ground durability requirement, being class 1 or "non-durable". That's still illegal in most Western countries (the USA being an exception. There you'll simply be sued to oblivion for selling such cladding) and such performance certainly would not have been acceptable in New Zealand prior to the 1992 Building Code).

i.e. there is a chicken and the egg issue in using the Building Code as a reference point for longevity, in that there is a strong inference to be made that the Building Code's longevity requirements have been tailored to radiata's (and particularly short-rotation radiata's) known and/or anticipated weaknesses, rather than representing what was acceptable prior to 1992. The Crown had, as at 1992, less than five years prior sold half of its forestries as a going concern in terms of producing construction worthy lumber, and was still at the time trying to sell the other half of its forestries, so it was financially incentivised to (and facing potential liaiblity if it did not) ensure that the second rotation radiata could continue to legally be sold for construction purposes in New Zealand, and if it did not provide the forestry purchasers with legal "cover" in the sense of being able to meet the legislative performance standards.

So, I am interested in all discussion/documentation that discusses longevity/durability, whether such discussion concerns performance by reference to pre-Building code standards/expectations, or the performance of the first rotation crop timbers, or by reference to harvest age, or the performance of non-radiata construction woods, or international standards, or any other metric. The documents will be what they are. Whatever the authors have chosen at the time to discuss/analyse longevity/durability in relation to, I'm interested.

Yours faithfully,

Edward Grove

Yours faithfully,

Edward Grove

Dear Edward

 

Thanks for your email.

 

I confirm we have continued our search for relevant information.  The
suggestion to talk to Doug was not to suggest the discussion would or
could replace our response to your requests.

 

Further to our earlier exchanges regarding the requests, I confirm the
clarified requests are:

Information between 1992 and now, either received by Scion from third
parties or written by Scion (either upon request by third parties or not
and whether for internal or external purposes) which gives advice on any
actual or potential causal link between the properties of Pinus radiata
juvenile/core wood and residential building failure after building
completion that has an adverse impact on the longevity (according to the
Building Code) and performance (including structural integrity) of the
residential building (which may or may not impact on building
weathertightness).

 

Information between 1987 and now, either received by Scion from third
parties or written by Scion which in any way sought to influence
communication by Scion (including its employees) regarding any actual or
potential causal link between the properties of Pinus radiata juvenile
/core wood and residential building failure after building completion that
has an adverse impact on the longevity (according to the Building Code)
and performance (including structural integrity)of the residential
building (which may or may not impact on building weathertightness).

 

We will be in contact but please do not hesitate to contact me if you have
any queries in the meantime.

 

Regards

Dear Edward

 

Further to my email dated 30 July 2020, I had previously indicated we
would respond to your requests today.

 

Unfortunately, it will not be possible to meet that time limit and we are
therefore writing to notify you of an extension of the time to make our
decision by a further 20 working days, to 7 September 2020.

 

This extension is necessary because your request necessitates a search
through a large quantity of information and meeting the original time
limit would unreasonably interfere with our operations. 

 

Since we finalised the clarified requests, we have been working through
Scion’s record of science outputs with relevant keywords and may be able
to provide information about outputs sooner than the extended due date. 
However, searching all Scion’s other electronic records with relevant
keywords (including emails) and historic hardcopy archives is taking a
significant amount of time.

 

You have the right to seek an investigation and review by the Ombudsman of
this decision. Information about how to make a complaint is available at
www.ombudsman.parliament.nz or freephone 0800 802 602.

 

If you wish to discuss any aspect of your request with us, including this
decision, please feel free to contact me.

 

Regards

 

Lynda

Dear Edward

 

Thanks for your email.

 

I confirm we have continued our search for relevant information.  The
suggestion to talk to Doug was not to suggest the discussion would or
could replace our response to your requests.

 

Further to our earlier exchanges regarding the requests, I confirm the
clarified requests are:

Information between 1992 and now, either received by Scion from third
parties or written by Scion (either upon request by third parties or not
and whether for internal or external purposes) which gives advice on any
actual or potential causal link between the properties of Pinus radiata
juvenile/core wood and residential building failure after building
completion that has an adverse impact on the longevity (according to the
Building Code) and performance (including structural integrity) of the
residential building (which may or may not impact on building
weathertightness).

 

Information between 1987 and now, either received by Scion from third
parties or written by Scion which in any way sought to influence
communication by Scion (including its employees) regarding any actual or
potential causal link between the properties of Pinus radiata juvenile
/core wood and residential building failure after building completion that
has an adverse impact on the longevity (according to the Building Code)
and performance (including structural integrity)of the residential
building (which may or may not impact on building weathertightness).

 

We will be in contact but please do not hesitate to contact me if you have
any queries in the meantime.

 

Regards

 

Lynda

Dear Edward

 

Further to my email dated 30 July 2020, I had previously indicated we
would respond to your requests today.

 

Unfortunately, it will not be possible to meet that time limit and we are
therefore writing to notify you of an extension of the time to make our
decision by a further 20 working days, to 7 September 2020.

 

This extension is necessary because your request necessitates a search
through a large quantity of information and meeting the original time
limit would unreasonably interfere with our operations. 

 

Since we finalised the clarified requests, we have been working through
Scion’s record of science outputs with relevant keywords and may be able
to provide information about outputs sooner than the extended due date. 
However, searching all Scion’s other electronic records with relevant
keywords (including emails) and historic hardcopy archives is taking a
significant amount of time.

 

You have the right to seek an investigation and review by the Ombudsman of
this decision. Information about how to make a complaint is available at
www.ombudsman.parliament.nz or freephone 0800 802 602.

 

If you wish to discuss any aspect of your request with us, including this
decision, please feel free to contact me.

 

Regards

 

Lynda
