Farm Forestry timbers AGM

Farm Forestry Timbers Society Inc. will be holding our Annual General Meeting at the NZFFA Conference in Feilding. Our AGM will take place on Saturday 8 April at the Feilding Civic Centre, at 5pm.


The first part of this year is an important time for our industry. There is a hefty review of the building code underway around timber and construction, and I'm representing Farm Forestry Timbers on three standards committees, each reviewing different standards cited by the building code. These are NZS 3603 (structural design), NZS 3602 (durability) and NZS 3640 (timber treatment). These standards have progressively restricted the use of our specialty timbers over time, simply because we haven't had representation at the table until now. I'm trying to turn that around, but from what I've witnessed so far it's going to be an uphill battle.

The notion of a level playing field, one where industry players all get along making rules that work for everybody, is quite different from reality. Vested interests are at play and self interest rules. To regain what we've lost now requires detailed evidence that justifies re-inclusion... a vicious circle when the evidence required is from a use that is not actually allowed.

It has become my job to produce detailed evidence supporting what I see as obvious, what is well known from a history of use, that different timber species have properties that are well suited to specific applications without treatment. Unfortunately, what is obvious to me is not something that representatives from chemical manufacturers, treatment specialists, scientists and conservative regulators sitting on the standards committee have any understanding of... natural timber in use. So why should they trust my word as someone who knows their timbers?

Of course natural durability, being variable, does hold a level of risk in terms of performance. So why even consider risk when this is effectively removed with blanket treatment? The committees job, after all, is to be confident that the rules work. What matters is that the consumer can sleep soundly at night, because the preservatives have been applied in the correct quantities and verified. Great for some (producers of radiata pine), but is this approach really necessary for all timber species and all applications? I'll continue arguing that it is not and that wood properties in many cases are well established from a history of use and that detailed research evidence is not always required for inclusion in the standard.

There will no doubt be some losses and there might even be some wins. What will emerge from the losses is direction on what research we need to undertake to strengthen our case for inclusion. We'll know what we have to do for next time. I also sit on the Specialty Woods Partnership (SWP) technical steering committee and it will be good to become aware of knowledge gaps that need to be filled for our "alternative" species to regain their place as acceptable solutions within a performance-based building code.
