D. Summary of Meetings - Observations

Our mission took place principally in
Papeete, the capital and by far the largest city in Tahiti. It is the center of commerce and essentially
all imports go to this Port before shipment to any of the 180 islands making up
French Polynesia (Tahiti). In 1999 Tahiti was the 11th largest
export market for softwood lumber with exports valued at nearly
$9,000,000. Our key contact was
Jean-Jacques JORDA, President of Polybois, a major importer of western
softwood lumber. He and Patrice
ANESTIDES, the firm’s Commercial Director had set up numerous meetings and made
all the arrangements for the workshops.
In addition they escorted us to most of the meetings and provided
translation. Organizations visited
included import trading firms, architects, contractors, wood milling, chemical
suppliers, inspection agencies and
housing authorities. In addition our
hosts had promoted the seminars in the local building material community and in
the press. About 15 individuals
attended each of the seminars. The
seminars consisted of: Dr. Morrell
covering the basics of wood technology, risk hazards, termite control and wood
treating technology; Hayward reviewing the types of preservatives, the
industry, US standards, Quality Assurance and safety information; and messengers Bond and Morris providing brief
presentations on their firms and the types of
products and services offered by
the industry. The seminars were
conducted with simultaneous translation and all attendees were provided with a
complete packet of guidance materials on use and specification. The seminar concluded with a lengthy
discussion of the issues related to treated wood in Tahiti.

Several factors are key to the use of
softwood in the region:
o There is a high risk for termite damage
throughout the region and the problem appears to be increasing. Fungal decay is also a consideration,
although it appeared to be less of a concern to the wood users.
o Pre construction ground treatments and post
construction controls for termites are not uniformly used and there appeared to
be little follow up with supplemental treatments after construction. There was also a concern that applicators
were diluting treatment chemicals to save money, further reducing the value of
treatment.
o While the necessity for treating all cut ends
is recognized and effective chemicals are
available, field treatments are rarely performed due to work force
attitudes. We observed numerous untreated cuts on one building over the course
of our visit. This largely negates the
value of treatment since it provides a pathway for termite entry beyond the
treated wood barrier.
o They generally build above ground or above water
on concrete piers.
o Douglas-fir is a preferred species and
Hem-fir is acceptable. The users were
concerned about strength- preferring the risk of decay due to poor treatment in
return for a higher initial strength.
o Because much of the design is exposed they
have moved away from the use of incised materials for aesthetic reasons. They also object to the green color of CCA
treated materials. They also rejected
the use of ammoniacal treatments, which would allow for deeper penetration
without incising, but darken the wood.
They recognize the potential for using the LOSP (Light Organic Solvent
Process) which does not color the wood and might also use solvent based
treatments from the U.S. Cost, however, was a major concern.
o While the need to use only treated materials
is understood and accepted, the market has a low level of understanding that
some treatment procedures will be less effective than others. Driven by
economics, the predominate western species used is unincised green
Douglas-fir treated with CCA. Such
materials are poorly penetrated with preservative and are likely to have low
retention levels. Not surprisingly, the
materials are not performing well. In
essence, French Polynesia has among the highest levels of risk in the world, yet
uses materials which would not be accepted for the lowest level of risk in the
US!

o They do not appear to have building codes or
standards in regard to treatment as we do in the US and as a result the market
uses the least costly material. There
also appears to be little recourse for failure. Insurance agencies only require
5 to 10 years of performance on new buildings and do not consider termites in
their risk models.
o There was some confusion with US standards
which are commodity-based as opposed to French or international standards which
are hazard based. As we move into full
implementation of our Use Category Standards we will want to prepare an
equivalency guide for use overseas.
o It is clear that a large portion of the
market is at risk of being captured by radiata pine from New Zealand and
Australia. There is both a cost and
exchange rate advantage. This species
has a high percentage of easily treated sapwood that does not require incising
to achieve acceptable treatment. This species, however, has lower material
properties and is more prone to twist and warp. In larger timbers, heartwood faces are also likely to result in
poor treatment. We observed one radiata pine structure which had some evidence
of failures
o They also use, and may be leaning toward
increased use, of steel and concrete construction, especially for commercial
and multi-unit housing structures. Even
within these structures, however, there are major quantities of wood and there
is a general desire to use wood.
o There are several other preservatives that
might better fit some of their specific needs but these are generally more
expensive and the market appears very cost sensitive.
o The people we met with seemed to appreciate
the benefits of standards and recognized that many of their problems originate
from the low standard of treatment they accept. Further they seemed open to the idea of doing something to
improve the product.
o The Utility industry uses treated Douglas-fir
poles generally treated with creosote but we also observed some CCA treated
poles. They have some termite issues
and we discussed with the local supplier the need for ongoing inspection and
maintenance.

E. Conclusions and Recommendations
We cannot help but conclude that radiata pine
(and alternative materials) represents a significant threat to our products if
the western softwood lumber and plywood
entering the country is not treated to an appropriate level to match the high
risk environment. The US producers will continue to supply the low standard
treated materials if that is what the market requests. The solution with the best potential for
success is to convince the market to specify and use appropriately treated
material and employ proper construction practices even though this will cost
more and disadvantage the competitive position of our products.
We suggested, and the business community
seemed accepting of the idea, that they form a loose working group to establish
some Tahiti Use Standards and guidelines that they could promote within their
country for western softwood. We also offered to provide guidance to this group
as needed. They asked that we provide
our recommendations for such a policy, which we agreed to do. While we are still discussing the details,
our basic recommendation will be:
o Require that all construction sites be
treated prior to construction with either a chemical barrier or a physical
barrier to exclude termites.
o Provide guidelines to property owners for
ongoing inspection and control after construction is complete.
o For all uses which are interior or where
visual appearance is not a concern specify that the material be incised prior
to treatment.
o Specify that CCA or other water borne
preservative treated material for above
ground use be treated to 0.25 pcf retention with a penetration of 0.40 inches
with provisions for quality control and inspection. The retention should be increased to 0.40 pcf for material in
ground contact.
o Lumber should be dried to below 40 % prior to
treatment.
o Treated wood should be inspected by an
accredited inspection agency after treatment to ensure that it complies with
the specification.
o Where color is a concern, specify stained
material, stain on site or consider other preservative systems that can provide
a clear appearance. The practice of
milling off the treatment to get a clear face should be eliminated.
o Every effort should be made to dispose of
construction waste in landfills and to discourage the population from using the
trimmed materials for cooking fires.
We believe that
failure to improve the quality of wood entering this market will create an
opportunity for other countries. Our
host estimated that French Polynesia imported 15 to 20 million board feet of
treated Douglas fir per year. While the loss of this market would not devastate
the region, it has important implications for other Douglas-fir using islands
in the Pacific and could start a trend away from our materials.
