ED'S NOTE
Just right
Shopping for
culinary items
might seem like a
whimsical pursuit,
but for me, it
became a test of
stamina, patience,
fitness and my
general ability to
keep from caving
at the sight of
something that is
almost-but-notquite what I'm
looking for.
M
y search for the perfect chopping board began
more than six months ago. What I really wanted in
a chopping board seemed simple enough; it had to
be wooden, something chunky, yet feminine, preferably
round, rough, old-worldy and beautiful enough to use as a
serving platter. I was looking for the perfect chopping
board, one that was just right.
I shook my head indignantly at countless plastic boards,
winced at the very thought of my knives grating on glass
and, although I came very close to buying a bamboo
chopping board, my inner drive to find that elusive
wooden chopping board was strong. Finally, my search
came to a glorious end just two weeks ago; I found a
Trudeau Boutique Vineyards bread board weighing in at
2.5 kilos and 40 centimetres in diameter. Round, rustic,
rough enough and just right, these unique chopping
boards are handcrafted from century-old French Oak wine
barrels that have slowly, lovingly aged Franschhoek wines.
I hold my prized chopping board and with wide eyes and a
smile imported from a long-ago childhood, I gently stroke
the rough texture, and lean in to closely observe the
Morse-code of the age old oak grain.
6
AUGUST 2012 //
I furl my fingers and with knuckles I knock, half expecting
to hear a hollow return. When the soft woody notes
resound, I turn the board around and see a wine-tinted
underside whose colour acknowledges a purposeful past,
a story of viticultural gestation and the unmistakable
history I am after.
A piece of wood with rough-enough skin, a deep enough
voice, a sturdy stature and a story inscribed on its belly has
found me. Not too smooth, not too small, but just right,
Goldilocks has found her chopping board. Although it
hasn’t taken us six months to put this issue of Timber iQ
together, the same kind of effort that went into my
chopping board pursuit went into sourcing and showcasing
the exquisite potential of timber. I hope you enjoy reading
this issue as much as I have savoured putting it together.

Financial foundation to boost growth
potential of forestry and wood products
As providers of raw materials to primary processing industries
for multi-sector use, the sectors of forestry and timber are
deemed to be economically significant with a high growth
potential. The South African National Industry Policy Framework
(NIPF) and Industrial Policy Action Plan (IPAP2) have identified
the sectors as being crucial to providing enabling opportunities
for the participation of rural, previously disadvantaged people
in economic growth.
The IDC’s support of the sector focuses on unproven technologies
and markets, which by their nature are higher-risk projects
with an anticipated higher return on investment. The Forestry
and Wood Products Unit (SBU) ensures that after initial funding
has been granted, a partner-relationship is formed with the
portfolio companies to facilitate ongoing engagement. This
means that strategic support, advice and guidance are
available throughout the project development as part of
the IDC’s Post Investment Management (PIM) activities.
expansion of forestry and wood plantation areas. Viable
projects are financed across the sub-sectors of forestry,
sawmilling, pulp and paper, furniture and biomass. Priority is
given to the development of timber and alternative energy
fibre resources; technology upgrades in the sawmilling and
pulp and paper industry; the establishment of local niche
board manufacturing, and the development of value-added
products to stimulate local demand. Additionally, the Unit
endeavours to support the expansion strategies of South African
companies beyond the country’s borders. As a leading
provider of finance to entrepreneurs and SMEs in the
Forestry sector, the Unit is able to act as a catalyst in finding
new opportunities and facilitating consolidation for small
furniture manufacturers.
Economic growth, job creation and poverty alleviation, particularly
in rural areas, are strategic objectives of the IDC – committed
to be a proactive, value-adding partner in the development
and implementation of forestry and timber projects.

Summer Living
The beautiful Summer House in Southern Burgenland by
Judith Benzer Achitektur combines steel, concrete and
wood for a harmonious reinterpretation of the organisational
framework of the Kellerstöckel, or wine house.
Words: Daniel Conradie
Photography: Martin Weiß | www.pool2b.net
I
t is often through the exploration of small scale
architectural works that conceptual ideas can be
realised. A humble summer house in Southern
Burgenland, Austria, explores a number of intriguing
concepts, but the most fascinating has to be the sheer
simplicity and clarity with which these have been
interpreted.
10
AUGUST 2012 //
The clients, an elderly couple close to retirement,
approached the architect with an interesting brief: design
a summer house that accommodates their mutual interest
in growing grapes and producing wine.
feature
When starting a design, architects often identify (and draw inspiration
from) vernacular architectural precedent (building styles unique to a
particular locale) in formulating an appropriate – and contextually
relevant – response, whether driven by climatic, functional or aesthetic
motivations.
The design and the formal language used to merge the residential and
agricultural aspects, as set out in the brief, pay tribute to a humble
building archetype commonly encountered on the Austrian landscape:
the Kellerstöckel.
Typical of the Southern Burgenland region, the wine house model’s
functional programme is split in two: a habitable residence sits perched
on a burrowed basement. Often the roofs are pitched – a common
response to the construction of buildings in areas that experience winter
snowfalls – and the entire construction is of timber.
These formal gestures became the primary parameters while the design
of the new residence progressed, in an attempt to re-interpret the
Kellerstöckel’s organisational framework and to produce a contemporary
rendition thereof.
Unlike the more traditional farm layout, whereby a farm house is
surrounded by various mono-functional outbuildings, the architect
merged the two typologies into a single element.
In effect, the differing aesthetic treatments traditionally imposed on
either (residential opulence versus industrial functionalism) are unequal,
and the architect responded to this imbalance by shifting the focus from
a contrast in finishes toward a contrast in the materials themselves.

In effect, the differing aesthetic
treatments traditionally imposed on
either (residential opulence versus
industrial functionalism) are unequal,
and the architect responded to this
imbalance by shifting the focus
from a contrast in finishes toward a
contrast in the materials themselves.
To expand on the concept of unifying the seemingly
heterogeneous elements, the architect chose to emphasise the
use of different materials and construction methods to
illustrate their individual identities: an all-timber construction,
containing the habitable aspect of the programme, perched on
top of a solid concrete base (containing the cellar). The
basement is partially burrowed to provide a more consistent
interior climate (a mandatory consideration in the design of
wine cellars) for the successful production and preservation of
wines.
The clever use of contrasting materials to accentuate the
seemingly incongruous merging of residential and agricultural
typologies creates a homogenous balance, as the architect
explains, between the cosy (wood) and the raw (concrete).

While vacant the built form
thus reads as a monolithic and
unobtrusive silhouette on the
landscape, but while occupied it
unfolds to reveal its contents.
As it was intended for the house to be inhabited only
during the summer months, a measure of security had to
form part of the building’s composition, accounting for the
periods of extended absenteeism. The solution selected
– a continuous mantle of larch planks – serves as the
primary skin of the building, but in lieu of an additional
layer to address this particular concern it was integrated to
form part of the building’s skin itself. Covering the
beautifully proportioned window and door punctures, the
skin is allowed to peel away via a series of hinged and
folding shutters. While vacant the built form thus reads as
a monolithic and unobtrusive silhouette on the landscape,
but while occupied it unfolds to reveal its contents.
The roof is a continuation of the wall cladding detail,
reinforcing the notion of a timber mantle enveloping the
entirety of the structure. A double waterproofing
membrane was used to accommodate the roof detail, with
the insulation layer acting as the drainage channel as well.
One membrane is placed directly beneath the timber slats,
while the second is located between the insulation and
timber substructure.
Larch is valued for its tough, waterproof, and durable
qualities and is often considered to be the recommended
wood variant in the construction of residences throughout
central Europe. Its ability to resist rot allows it to be left in
its untreated state – an important factor to consider when
using any natural timber. As the timber ages, it will turn a
beautiful silver gray.
The placement of the windows attempts to introduce and
highlight the spectacular surrounding countryside. The
largest opening, situated on the Southern façade, frames a
stunning landscape, while the horizontal slit on the
Western elevation captures a panoramic view of a
neighbouring farm. As the house is situated on a hill, the
architect introduced punctures on all four elevations to
take advantage of its placement and to maximise the
ingress of natural light into the house. It was important not
to make the openings too large, as they reduce the energy
efficiency of the house, but to allow for the adequate
ventilation and cooling of the interior during the summer
months.
Apart from the security offered by these wooden shutters,
they also serve as a method of dealing with aestival
overheating (a common characteristic of the Southern
Burgenland region) by effectively controlling the amount
of sunlight permissible into the space.

One of the striking aspects of the wooden mantle is the
crisp corners achieved; folded sheets of copper allow for
the fixing of the timber planks at the corner junctions. The
reserved material palette is enhanced simply by means of
each one’s articulation within the larger scale of the
project. This fact becomes even more prominent when
viewing the design of the interiors, where timber, steel
and concrete meet harmoniously – each layer contributing
to the overall composition.
This project manages to encompass a number of vital
lessons, but the most important is the reminder that with
the firm comprehension of each material’s characteristics
come built works that express the inherent qualities of
each without any pretence. The Summer House represents
architectural honesty on a landscape that requires nothing
less.

nspired by Scandinavian simplicity and Dutch
originality, 25 year-old Cape Town design sensation,
Laurie Wiid, weaves design magic with his favourite
material – cork.
Personally, I find cork to be a warm material, it has a
beautiful texture, and it smells so good! It’s a material you
can trust, it doesn’t warp and one gets a variety of grades,
from rough granules to fine granules.
Van Heerden, born in 1987 in Cape Town, started his
studies in industrial design at the Cape Tech in 2007, but
decided to venture more into the practical side of things.
From there he was employed by Bronze Age Art Foundry
until 2009, where he worked with some of his creative
heroes, including Cecil and Boyd, William Kentridge and
Wim Botha, in a stimulating environment where he learned
various invaluable skills and techniques.
Cork also attracted me when I read about its sustainability:
The material is extracted from the Sobreiro (Cork Oak)
without having to harm or destroy the tree and is nontoxic, recyclable, renewable and fire-resistant. Like timber,
cork boasts a great atmospheric CO2 fixing capacity and
through production, generates minimal waste and usage of
resources.
After gaining ample practical experience in the field of
design and manufacturing and also being the assistant to
Wim Botha for almost two years, Wiid Design was created.
Wiid Design focuses on producing truly unique products
designed and manufactured in Cape Town, South Africa.
JR: What are the benefits and drawbacks of
working with cork?
LW: The benefits of working with cork include: its softness
and flexibility, rendering it easy to machine; it sands well
and does not clog tools or abrasives; it is renewable and
biodegradable; it forms a durable, high density surface; it
is safe for food storage; it is lightweight, naturally hypoallergenic, anti-microbial and anti-fungal.
JR: What do you like about using cork in your
work?
LW: The material is just amazing. I choose to work with
cork because of its many properties, which make it a
flexible material to incorporate into a variety of products
with different uses. Cork is a durable, high-density surface
that is resistant to wear, slip-resistant, lightweight,
impermeable to liquids and also easy to machine.
The downside to working with cork is the fact that it is not
that easily obtainable in South Africa, it is generally quite
expensive and is only supplied in certain sizes and
thicknesses.

JR: How has Wiid Design been
received by Cape Town and its
people?
LW: People love my work in Cape
Town and I get lots of interest. I see
Cape Town as a very European city
and my customers understand the
uniqueness and quality of my work.
It is always important for me to keep
my work original and this is not just
in the design of a product, but also
with regards to materials!
Actual cork products are still a very
new thing in South Africa and it is
important for me to showcase the
material as a high quality material,
and not something that is cheap or
easily obtainable.
JR: Are you proudly South
African?
LW: Of course! I love South Africa;
there are so many cultures and
different lifestyles. I feel really free
in this big county, but the only thing
I would ask is that the
manufacturing industry and also
larger companies would start
supporting young designers.

This type of support can be given in a few
ways: financial support (sponsorship when
seeing potential), production, assistance in
prototyping products and guidance on how to
keep manufacturing costs low.
Also, what’s very important is that
manufacturers are enthusiastic about new
materials and products and help newcomers
develop their products.
One company that has really been amazing
when it comes to supporting me for the last
two years is Amorim Cork. Joaquim, the
managing director, is a real entrepreneur and
has been assisting me with cork from the very
start! We are planning a cork exhibition and he
has also instigated an amazing recycling
initiative in the Western Cape where more than
300 000 cork stoppers have been recycled.
JR: Your overall image and design
offering seem to straddle local as well
as global aesthetics. How do you
respond to this statement and if you
agree, why?
LW: I agree. I try to keep my work simple and
focus on quality and originality. The more
original the piece, the more difficult it
becomes.

I try to create desirable collectors’ items; beautiful shapes,
colours, textures and interesting materials form part of my
design process. When my products are designed, it is a
personal process and I take it very seriously, which might
be why people are so drawn to them.
European design has always been a big inspiration to me,
especially the simplicity of Scandinavian design and the
originality of the Dutch. Wiid Design will be launching a
few more products this year which will be true collectors’
items, so readers should keep an eye on my website.
JR: Where to from here for Wiid Design?
LW: My main focus now is to not bring out mass produced
pieces, but to focus on bringing out collectors’ pieces,
where the use of material vs. function will play an
interesting role. I am currently designing two 2.7m solid
cork dining tables, which will be available in the new
‘black cork’. An indoor and an outdoor version will form
part of the collection.
A cork exhibition for 2013 with Amorim cork is also in the
pipeline and maybe another collaboration or two with
various artist to produce some amazing collectable pieces!
Wiid Design’s products also incorporate materials such as
concrete, terracotta, felt, leather, wood, porcelain, cast
iron, stainless steel and state-of-the-art energy saving
LEDs. Wiid Design was nominated as a finalist in the
Absolut Visi Designer of the Year competition in the
emerging designer category for 2011 and has been
featured in most top magazines and newspapers in South
Africa, including The Weekend Argus, The Times, Property
Magazine, Visi, Elle Decoration, House and Home, House

morning show ‘Expresso’ where Laurie currently
showcases some of his work.

Silver linings
The Cloud House is a playful, yet sensitive addition and renovation
to a double-fronted Edwardian house in Melbourne, Australia.
Photography: John Gollings
feature
O
ver the course of close to a century, this house
has received several additions and
modifications. McBride Charles Ryan's work
for the house is designed in three parts, which
allows for a sequence of distinct and unexpected
episodes, with glimpses previewing oncoming spaces
and experiences as one moves through the home.
The street façade has been left to demonstrate the
clients' respect for the evolution of the character of the
area and the modest street alteration belies the extent
of the comprehensive internal renovation work.
The spaces within the original structure are largely
white in colour, united by an exotic floral hallway carpet.
This journey through the space is followed by
encountering a disintegrated red-coloured 'box'. This is
the kitchen, at the heart of the property, which acts as a
bridge linking the major spaces.
A cloud-shaped extrusion is the unexpected final space.
Following the form of a child-like impression of a cloud,
it is a playful addition where family and friends can eat
and have fun surrounded by the curved form.
// AUGUST 2012

feature
The new living addition faces due south while allowing
controlled north sun into the living area and providing effective
cross ventilation. The form of the 'cloud' conforms to setback
regulations without appearing obviously determined by them.
The extrusion creates a dramatic interior language where walls
merge seamlessly with the floor and ceiling. The craftsmanship
is remarkable throughout and has a sense of care one typically
associates with the work of a cooper or wheelwright.
Bob Quinn of Quinn Constructions, whose work is commended
by the architects, says, “I sourced all the spotted gum decking
boards, which have been used to line the cloud, from a company
called Greenhills Timber in Thomastown. They were reliable and
cheaper than straight from the mill in Queensland.”
While the geometry is playful, the extrusion is essentially a
contemporary barrel vault.

Pavilion in a Million
Timber iQ's editor talks to Marco Casagrande about his latest
addition to the Taipei cityscape and how, through design and
material choices, the structure engages with the city and its people.
Photographs by: AdDa©
Drawings by: Marco Casagrande
C
asagrande was born in 1971 in Turku, Finland,
and completed his studies at the Helsinki
University of Technology Department of
Architecture in 2001. From early on,
Casagrande began mixing architecture with various
other artistic disciplines, as well as science, which has
resulted in his famous eco-conscious installations
across the world.
Casagrande’s work and teachings move freely
between architecture, urban and environmental
design and science, environmental art and circus,
culminating in a hybrid of architectural thinking
called “commedia dell’architettura,” a broad vision of
built human environment tied into social drama and
environmental awareness.
In a highly industrialised area of Taipei, Marco
Casagrande’s Cicada pavilion represents a gentle, yet
bold and refreshing interjection into the concrete
hardness that is synonymous with a working city and
offers a welcome cocoon for escape from the city, and
industrial meditation.

JR: Marco, how are you trained and from what or
whom do you draw your inspiration?
MC: I studied architecture, but the real studying has been
through my work and meeting with people. Childhood in
Lapland is as important as university, if not more. Child-me
keeps me in connection with nature. I am more inspired by
movie directors than other architects. Tarkovsky,
Eisenstein, Lang, Bergman, Kurozawa, Coppola in
Apocalypse Now, Cubric, etc. Books are also important. My
biggest inspiration is nature, including human nature.
"Ruin is when something manmade has become part of
nature. Local knowledge is one
of the elements that can turn
the industrial machine into an
organic machine."
JR: What projects and/or events led to the
design and creation of the Cicada pavilion and
why was this project executed in Taipei?
MC: I worked the first time with bamboo and organic
structure in Shenzhen Biennial in 2009 together with
Hsieh Ying-Chun and Roan Chin-Yueh. This was my first
encounter with the South-Chinese local knowledge of
bamboo.
Cicada’s client visited the Shenzhen Bug Dome and later
on wanted something like that in Taipei.
The idea is to ruin the industrial city. Ruin is when
something man-made has become part of nature. Local
knowledge is one of the elements that can turn the
industrial machine into an organic machine.
JR: you sought to create a structure that is out
of place, both in terms of time and material.
What instigated the need to do this and how does
the Cicada pavilion fulfil this need?
MC: Modern man has to take the liberty to travel 1000
years back in order to realize that things are the same.
Cicada offers this possibility. High density urban
communities have been living in good harmony with the
surrounding nature, but we have forgotten this. In order to
reach the Third Generation City we need to forget this
forgetting and let nature in. Modern man in a box is
doomed to dementia.
JR: Why did you choose to use a fire pit and
benches inside the pavilion?
MC: Making open fire inside the modern city is interesting
for me. Citizens around the fire sort of melt down and
become human again. The benches are like insects in this
space that can be used for many purposes. The organic
form is made for the dramatics of the space and for the
way light comes in. The hole is for a vertical axis and in
connection with the fire-place.

"Modern man in a box is doomed to dementia."
JR: What led you to making use of a vacant site
that is awaiting development for the creation of
the Cicada pavilion? And will the pavilion be
destroyed in time to make room for other
developments?
MC: In Taipei the slow circles of official development offer
more fruitful possibilities for unofficial microdevelopment. Community gardens and urban farms are
taking place on similar sites like Cicada – waiting for
development. Some farms or gardens can be 20 years old
on sites that, for example, banks are fighting for.
Meanwhile, grandmothers are farming and tuning the city
towards the organic. This is Urban Acupuncture. Cicada is
following this method. The pavilion will get destroyed and
the site will get developed and new holes in the city’s
mechanical reality will open up for organic growth.
JR: Why did you choose to use bamboo in this
project?
MC: The whole structure is bamboo - amazing material
when it comes to organic strength. For anchoring, there is
a pile of top-soil outside as the counter-weight. The
bamboo is from Central Taiwan and it is not treated in any
way. Similar kinds of structures have been done forever.
Only the city is a new thing.
JR: Why was ivy planted along the sides of the
structure? How does this form part of your idea?
MC: The creepers provide good micro-climate and change

become a structure for urban bonsai. Architecture without

JR: How do you respond to Cicada being "insect
architecture"? What does this mean to you?
MC: I have studied a Phimenes Sp. Wasp making his cocoon
out of cement that he stole from me. It understood the
structural possibilities, immediately mixing the cement
with mud and some pieces or straw and sticks. His cocoon
was fantastic and has been the inspiration for Bug Dome,
Cicada and more to come.

JR: How have people responded to your designs?
MC: I have been surprised by how much people love this
space. This is wonderful, especially when all kinds of
people from different backgrounds like Cicada. Even
children like it. It looks like the organic space is doing
some magic for the industrial man. He feels good in it. He
remembers something, feels hope.
JR: Marco, what projects lie ahead in your
future? What is the trajectory of your career
path and what do you hope to achieve through
your work?
MC: I don’t have a career path. I believe in accidents. In
future I will work more with insects and local knowledge. I
want to see the Third Generation City, the organic ruin of
the industrial city. I will also develop further the
possibilities of Urban Acupuncture for punctually tuning
the mechanical urban machinery towards the organic. I
also want to create more good homes for good people and
operate freely in-between architecture, environmental art,
ecological urban design and other forms of art and science
within the general field of built human environment.
Casagrande views the city as a complex energy organism
in which different overlapping layers of energy flows are
determining the actions of the citizens, as well as the
development of the city. By mixing environmentalism and
urban design Casagrande develops methods of
manipulation of the urban energy flows in order to create
an ecologically sustainable urban development towards
the so-called Third Generation City. The theory of the
Third Generation City views the urban development as the
ruin of the industrial city, an organic machine ruined by
nature, including human nature and urban acupuncture as
a cross-over architectural manipulation of the collective
sensuous intellect of a city. Architecture is in the position
to produce the acupuncture needles for the urban chi.
Weeds will root into the smallest cracks in the asphalt and
eventually break the city.

DIY
Summer is in the air and
it's time to make sure your
deck and pool are in
tip-top condition!
D
uring the current season of DIY with Riaan, he
teamed up with Senor Splash who stock a variety
of fibreglass pools, which are available in a DIY
kit. In this particular project, the team wanted
the pool level with the existing veranda. In order to do so
they excavated only 700mm of soil and built a wall to
support the pool.
32
AUGUST 2012 //
The pool is then carefully placed within the walls. Water
can now be put in, while the level is constantly checked.
The pool is completed with a wooden deck. The support
beams are planted a day prior to the building of the deck.
Saligna wood is used for this deck and is specifically grown
by the Cashumi Wood Group in Tzaneen.
DIY
Riaan uses Eureka’s decking screws on this deck. Woodii
Klerksdorp assisted with the building of the deck.
For more information on this project visit
www.diymetriaan.co.za
Top tips for decks:
•Always use a high quality deck seal
•For a new deck: Seal the deck with 2 to 3 coats and reseal just before the rainy season
•Seal your deck twice a year
•Clean your deck by using washing powder and water.
Scrub with a broom and rinse with clean water, seal if
needed.

Good reasons
to consider
building a
timber frame
home
Many people have asked why it is that I prefer to design timber frame
homes and, more specifically, what the advantages of a timber frame
home are. Here are 10 good reasons to build your new house using
timber frame.
Words: Jacques Cronje
1
Touch the
earth lightly
The choice of a timber frame home is going
to substantially lower your carbon footprint.
Trees absorb carbon as they grow and this
carbon is locked away when the timber is
used for construction. So the more timber
you use instead of more energy and carbon
costly materials, such as masonry and
concrete, the lower the carbon footprint of
your home. Timber is also a totally renewable
building material. In addition, because of the
relatively light weight of timber frame
materials, less energy is consumed by the
transport of materials.
From a purely ecological perspective, a lot
less damage is done to the site immediately
surrounding a building project when building
with timber frame. This is because the work
predominantly consists of ‘dry’ trades where
products are ‘fixed’ and installed as opposed
to ‘wet’ trades where products are mixed and
applied on site, meaning, quite simply, less
mess.
34
AUGUST 2012 //
2
Keep cool
The structure of a timber frame wall is essentially a hollow cavity with
evenly spaced structural timber studs. It is the nature of this cavity,
along with the fact that the high insulating properties of timber
prevent ‘thermal bridging’, that allows the wall to be easily filled with
as much insulation as is required to produce a thermally efficient home
- as long as it is designed correctly in terms of optimal orientation and
positioning of glazing, of course. The amount of insulation required for
optimal efficiency, as well as to comply with the recent SANS 10400
Part XA Energy Efficiency regulations, differs depending on the climatic
zone in which you are building.
3
Keep your options open
Despite its history as a traditional building material, as the trend
towards the use of sustainable materials increases, timber is also
gaining popularity with designers and architects as a material in
contemporary architecture. Technological advances in design software
and fabrication technologies are now starting to allow timber to be cut
and fashioned to any shape you desire. So thanks to the extreme
versatility of timber, your timber home could be anything from a
humble log cabin, to a grand Cape Cod style beach house, a sleek
glazed all round clad post & beam pad enclosable by sliding shutters,
or a digitally crafted open plan contemporary house with a freeform
double curved roof. The choice is yours.
industry insight
4
Change is inevitable
Families get bigger and families get smaller. Children move out, older
parents move in. You accumulate more stuff, occasionally edit, but
mostly accumulate still more stuff. Over the lifespan of a typical house
countless changes occur with regards to its spatial requirements. And
you can be sure that this will at some stage involve building new walls,
or breaking old ones down, expanding outwards or upwards or opening
up.
Whatever your future change requirements, they will be easier, quicker,
less intrusive, and usually a lot less messy with a timber home than
attempting to make changes to a conventional brick and mortar home.
5
less is more
The first question many people ask when enquiring as to the estimated
cost of a house is ‘How much is it going to cost per square meter?’ As
there are so many variables, for example, finishes, proportion of
windows and doors to blank walls (windows are more expensive than
the equivalent area of wall), and the complexity of the design, that
unless the design and finishes have been decided upon, the question is
not that far off the ‘How long is a piece of string?’ question.
A more interesting question to consider may be, ‘How many square
meters of internal floor area you getting as a proportion of building
area? Did you know that, because timber frame walls are so much less
bulky than brick walls, you gain approximately 1m2 of internal floor area
for every 7 running metres of external wall length? The math is like this;
typical cavity brick wall at 300mm (including plaster) less typical timber
frame external wall at 150mm (including lining and cladding) equals
0.15m2 of floor area saved per metre of wall; multiply by 7 RM and you
get 1.05m2. So next time you are comparing ‘m2 rates’, don’t forget to
factor this in to your sums.
6
Time is money
Literally, when it comes to building – assuming you own or are paying to
live where you do while building. If you have just sold your house in
order to build a new one, you will presumably be paying occupational
rent. If you want to sell on completion of the new build, the sooner you
can do this the better. Renting speaks for itself. If you are building a
guesthouse or lodge, the sooner you can get bums in beds, the better
for your positive cash flow.
Whichever way you look at it, a longer time spent building costs you
more. Now consider the fact that a timber frame home typically takes
half to three quarters of the time to build than a conventional brick and
mortar home.
36
AUGUST 2012 //
7
Rest Assured
Besides the knowledge that you are making
a positive contribution to global
sustainability, you can also have complete
peace of mind about the sustainability of
your investment. Timber frame homes are
included in the South African National
Building Regulations standards, in SANS
10082, Timber Buildings. When built to
these standards they also automatically
achieve the standard required for
registration with the National Home
Builder Registration Council (NHBRC). They
are also easily designed to meet the
requirements of the new Energy Efficiency
regulations, SANS 10400 Part XA.
Build using a builder who is member of the
Institute of Timber Frame Builders and you
will also have the backing of an
organization with a 30-year track record of
promoting and maintaining acceptable
standards in timber construction in South
Africa.
8
Stay safe & sound
Timber is strong, light and reliable, making
timber construction on site simpler and
safer than concrete or steel construction. In
terms of structural material, radiata pine,
for example, has a strength-to-weight ratio
that is 20% higher than structural steel,
and more than four times that of
unreinforced concrete in compression.
Timber is also flexible, meaning less chance
of structural damage typically caused by
heaving clay, or the settlement cracks
typically found in masonry construction at
the top corners of doors and windows.
Modern timber construction also has
increased fire protection due to the use of
non-combustible linings protecting the
frames, the availability of fire retardants,
and designing for safety by using mass
timber with sufficient charring rates. Safety
in the case of a fire is all about safety of the
occupants, and timber homes, designed
correctly, meet all of the fire safety ratings
and requirements.
industry insight

home & dry
deal with people who care
With a correctly designed and built timber home you
will never have to worry about typical brick
homeowners’ issues, such as rising damp, or for those in
the Cape, moisture breaching the cavity. Furthermore,
arrive home on a cold winters evening, and a cozy
fireplace or heater will heat the home up in no time. This
is because, due to the low thermal mass and therefore
low thermal conductivity of timber frame construction,
the structure itself won’t need to absorb heat to warm
up before you can warm up the space.
Why is it that there are magazines, websites, online
interest groups and forums, and building awards dedicated
to timber construction? Now I’m not saying that builders
who don’t specialize in timber construction don’t care
about their work, but you can be sure that most timber
builders are passionate about working with wood and take
huge pride in their craft. So if you are going to be going
with the lowest bidder (which in all likelihood you are),
why not ensure that you choose to have your home built by
people whose work is their passion?
Use timber cladding in some of your living areas and
you’ll also get the additional benefit of the feeling of
warmth and coziness exuded by natural timber.

Tintswalo Property Group
stamps its authority on the SA
property development market
There is little doubt that the South African commercial property
market is in a strong position. In fact, according to Investment Property
Databank's (IPD) 2011 report, this market has outperformed all other
markets in local currency terms for the past seven out of nine years.
news
news
O
n the back of these favourable market
conditions, property development and
management company Tintswalo Property
Group has flourished, establishing a significant
impact across the length and breadth of the South African
retail and boutique lodges landscape.
The company is a leading retail centre developer, and is
currently engaged in expansion across the country in
emerging towns and cities, such as Bethlehem in the Free
State, Queenstown in the Eastern Cape, and Zeerust in the
North West Province.
Tintswalo Property Group CEO, Lisa Goosen notes that the
company’s considerable expertise and success provide a
substantial advantage.
“The Group has many years of experience, considerable
financial knowledge, an impressive portfolio of existing
properties, and a comprehensive understanding of the
unique South African context. “As such, our company has
the requisite expertise to offer the highest level of
excellence, quality, and collaboration in retail property,
ensuring that our investors and tenants alike receive
viable and well-planned developments. Tintswalo
Property Group will continue to build on these lucrative
foundations, recognising opportunities for people
examining property- and retail development options.”
Tintswalo is a Shangaan expression meaning ‘the
intangible feeling of love, gratitude and peace bestowed
upon someone offering you a meaningful and worthy gift.’
Goosen says that this phrase describes the company’s
business philosophy perfectly, as it always aims to
exchange above what is expected, and deliver more than is
promised.
She adds that the company’s hands-on business style
allows them to provide their clients with increasing asset
values which enhance the areas in which they are located.
Goosen explains that an important aspect of this value
offering is furthering community development. Therefore,
she notes, Tintswalo Property Group always embarks on
community projects in underprivileged areas, ensuring
that a developed centre also creates a safe, clean and
aesthetic environment. This action ensures that
communities are also able to prosper from the company’s
commercial developments.
Its commitment to community development has also
resulted in the company undertaking several Corporate
Social Investment (CSI) projects. Pertinent examples
include Tintswalo Property Group’s involvement in
aiding youth development through the ‘Youth for
Human Rights’ and the ‘Truth About Drugs’
programmes. The former initiative educates young
people about their basic human rights, while the latter
informs them about the inherent dangers faced when
using drugs.
40
AUGUST 2012 //
Goosen concludes that the country’s bright prospects will
aid the company’s growth ambitions.
“Tintswalo Property Group firmly believes in the future of
South Africa, and is eager to contribute to the country’s
growth.
As such, we intend to develop new centres every alternate
year, and ultimately manage our own portfolio of no less
than 10 centres. These will not only provide our clients
with a world class property of enduring quality, but also
add considerable value to adjoining communities.”
About Tintswalo Property Group
The Tintswalo Property Group, which currently
employs 260 people, was founded by Ernest and Gaye
Corbett in 1975 as Century Retail Development,
which developed retail shopping centres in rural
areas as its primary business. In 2003, the group was
joined by the Corbett’s’ daughter Lisa and her
husband Warwick Goosen, who together started the
five star Tintswalo Lodge collection. The company has
subsequently become known as the Tintswalo
Property Group.
About Tintswalo Lodges
Tintswalo Property Group boasts three five-star,
uniquely South African and eco-styled boutique
lodge destinations. Tintswalo Safari Lodge is located
in the Greater Kruger Park, Tintswalo at Waterfall is in
Kyalami, Johannesburg, and Tintswalo Atlantic is
located on Chapman’s Peak Drive, Cape Town.
Tintswalo Manor House is a fourth lodge under the
Tintswalo Property Group, and while it is as equally
opulent as the abovementioned, it is better equipped
towards a local family market.

Zai CORE Axe
by Kacper Hamilton
The Zai CORE Axe was designed by
ECAL/Kacper Hamilton for Swiss
ski company Zai.
product news
T
he CORE Axe consists of a helve and two interchangeable heads.
The straight shaft helve is made from a sandwich of carbon fibre
and ash wood. The layering construction is inspired by Zai’s
process and philosophy of making skis using raw and contrasting
materials in Disentis, Switzerland. Carbon fibre is used to provide
strength whilst the ash wood forms a protective shell around the core
and pays homage to the heritage of a traditional axe.
The form of the helve has been refined to be slim and lightweight,
reducing the thickness substantially to 13mm along the spine. The
weight of the axe is thereby focused at the head, generating greater
striking momentum and efficiency when cutting or splitting wood.
The two heads are made from forged high carbon steel with a blackened
finish. They can be changed using the integrated quick release system,
allowing for secure head attachment, easier sharpening and safer
transportation. Each head has a different function; one is for felling
trees and the other for splitting logs of wood.
Zai CORE Axe is a quintessential companion for the mountains, around
the chalet or on a trek.

Industrial CAT scans can now
be done on campus
Ever wished there was somewhere you could get a 3D scan - similar to
that of a CAT scan - of a piece of wood, metal or vine? Thanks to the newly
established Computed Tomography (CT) scanner facility of Stellenbosch
University's Central Analytical Facility (CAF) this is now possible.
A
s part of CAF, this multi-user facility is open to
both academics and commercial clients from
industry. It is based in the Department of Forestry
and Wood Science and was funded through the
National Research Foundation and Stellenbosch University,
through a grant obtained by Prof. Thomas Seifert.
With micro-focus X-ray CT scanners one can nondestructively slice and image the inside of materials, by
providing a two-dimensional (2D) or three-dimensional
(3D) look into and through materials at a high spatial
resolution. The resulting data provides information on
different material properties based on density variations
in full 3D.
“Our new industrial sized scanner uses the same type of
technology as a medical-type CAT or CT scanner does,”
explains CT scanner facility manager Dr Anton du Plessis,
who is an alumnus of the SU Department of Physics.
“However, it can penetrate much more dense objects than
just merely tissue and bone that medical scanners can do,
and can even be used to investigate steel and rock
samples.”
Forestry and wood science
One of the major fields of interest is the scanning of wood
samples from trees, which is the expertise of the grant
holder Prof. Thomas Seifert. Having done similar work in
Germany, he now continues this work through a variety of
student projects.
One such project involves the scanning of wood disks and
drill cores to relate density variations of the tree rings to
tree stress and climate change. Other applications in wood
science include the quantification of growth stress
induced by fire damage and the quantification and
distribution of resin pockets. Structures in wood can be
assessed on the macroscopic and the anatomic level. The
main objectives are to explain the structural variability of
wood as a response to environmental, pathological and
silvicultural changes in the environment and to obtain a
better understanding of the tree-environment interaction
of indigenous and introduced commercial species.
Further work will be conducted to assess and improve
quality of wood based products.
The General Electric Phoenix model V|tome|x L-240
microfocus CT is one of the most versatile scanners on the
market, and comes with two tubes for different
penetration and resolution. It covers a large range of
resolutions from 1-150 micrometres, as well as a variety of
sample sizes up to 50 kg.
“The smaller the sample, the better the resolution,” he
says.
“The number of potential applications is nearly limitless,
and users from extremely diverse fields such as wood
science, viticulture and engineering can all use this stateof-the-art technology,” believes Dr du Plessis. “This stateof-the-art technology is now available as a service to local
manufacturing industry as well; especially those
companies already using x-ray imaging will be able to
make use of the advantages gained with the 3D
capabilities of this type of imaging.”
44
AUGUST 2012 //

Viticulture
Another interesting application is in Viticulture, in
particular the scanning of vine grafts. Because the
technique is non-destructive and various 2D slices can be
made from the 3D data set, more information on the
internal structure of the vine graft and the connections of
xylem from old to new sections can be extracted.

Dimensional measurement /metrology
In a similar type of application, CT scanning of mechanical
components allows them to be dimensionally measured,
especially useful for example with interior diameters of
closed components. In the example below, various parts of
a wood boring tool were measured after scanning the tool.
Engineering and materials analysis
Another major application field is in the inspection of
mechanical components to check for porosity and microcracks. In one such example shown below, a medical
implant (jawbone) was scanned, which was produced using
laser additive manufacturing at the Central University of
Technology’s Centre for Rapid Prototyping and
Manufacturing. This particular component showed no
structural problems even though it was produced in its
entirety in one single process.
Future work in this direction will involve the use of CT
scanning to quantify porosity of components to improve
the process especially for new materials and new
processes being developed. Quality control is also
possible with either the fast 2D inspection or full 3D
inspection.
46
AUGUST 2012 //
Dimensional measurement of objects finds a particular niche
application area, and includes the measurement of distances in
enclosed objects, the accurate measurement of enclosed volumes
and even the surface measurement of objects producing surface file
output such as STL format. This dimensional control is particularly
relevant in reverse engineering and rapid prototyping processes.

Anyone requiring high resolution non-destructive 2D or

One of HUBTEX’s signature products, the Fourway Sideloader is a very robust and compact vehicle developed for indoor and outdoor use.
Hubtex Hits S.A.
Leading materials handling equipment supplier in SA, Goscor Lift
Truck Company (GLTC), part of Imperial's Goscor Group, has secured
the sole agency for German-based Hubtex products in southern Africa.
G
LTC MD Darryl Shafto says Goscor is pleased to be
partnering with a company that makes trucks of
such outstanding quality. “Hubtex has really
made an indelible impression worldwide for their
quality, ingenuity and service,” Shafto says.
Shafto adds that HUBTEX’s wide range of products will
enable GLTC to broaden its offering of materials handling
solutions in the local market. “With HUBTEX’s four-way
reach trucks, as well as their lift trucks that can handle
long loads, new markets in which GLTC has not operated
before are now open to us. These markets include the steel
and timber industries, the glass industry, builders’
merchant outlets, and others,” Shafto says.
In fact, with products that range from simple manual
forklift trucks to high-lift picking trucks and rail-mounted
lift trucks with load capacities ranging from 0,8 tons to
350 tons, HUBTEX’s product range covers several
industrial sectors, including, of course, lifting and
transport equipment for the textile industry – weaving
mills and warp knitting factories - where HUBTEX started
business.

kitchen manufacturers and others. “Many of the more
common products that are lifted and carried include
chipboard, plywood, timber roof trusses, construction and
finished timber along with kitchen worktops, and doors,”
says Shafto.
Some of the more important HUBTEX
products include:

up to 10 tons, these three-wheel hydrostatically driven
Fourway Sideloaders are all-purpose vehicles, which can
be used for the transport of long loads in narrow aisles, or
as conventional front loaders for conventional pallet
stacking.
Electrical Multidirectional Sideloaders
The second series of signature products are the Electric
Multidirectional Sideloaders (EMS). These are suitable for
the versatile handling of long loads, stacks of metals
sheets, chipboard, tools, cable drums, rollers, oversized
pallets and round-bar stock. With capacities from 0.8 tons
to 50 tons, the EMS is suited to both indoor and outdoor
applications and can be used in guided or unguided
operation in very narrow aisles. They also feature
multidirectional steering to maximise maneuverability.
The three most popular HUBTEX EMS series are the 2150
series, the 2120 series, and the 2130 series. The 2150
series is a robust machine with extremely high load
capacities. It transports and handles long and heavy loads
in combined indoor and outdoor applications. Due to its
powerful travel motors and large plastic tyres, it can reach
speeds of up to 16km/h. These sideloaders can be used in
outdoor areas and are proven workhorses even in poor
weather conditions.
These pickers are equipped with articulated two-piece
chassis, robust lift masts, three-phase brushless motors, a
unique information terminal with colour display and
ergonomic and comfortable operator workstation for
enhanced efficiency.
“HUBTEX’s picking machines meet warehousing and
transporting needs for a wide variety of industries and
product lines,” says Shafto. “Again, as with the more
conventional Hubtex trucks, they will help us in those
areas we have not been into, like the large volume timber
and steel businesses and many more.”
HUBTEX has a wide variety of other products, including a
compact front-lift for moving heavy loads in a very
confined space where conventional front-loaders cannot
operate; the series 4120 forklift reach truck, with
capacities from 3500 kg to 6000 kg, which is an
alternative to conventional reach trucks with restricted
standardised capacities; and rail-mounted lift trucks,
exclusively designed for in-plant transport, with capacities
of up to 150 tons.
Lars Beuel, Hubtex sales manager material handling, says
he is optimistic about the new venture in South Africa.
“We saw very quickly that GLTC is a consummately
professional company and that our products will add
strategic value to their current range. I look forward to
working with Darryl and the Goscor team and to building a
memorable partnership in that country,” he says.
Goscor Lift Truck Company has established a powerful
reputation in South Africa as the sole local distributor of
Crown, Doosan and Bendi products and has, since 1984,
offered a world-class sales and support service in the
materials-handling equipment industry.
The 2130 series machines are known for their versatility.
With multidirectional steering, they are the entry level for
heavy load handling. With their soft plastic tyres, they
handle long and heavy loads of up to 6 tons in both indoor
and outdoor applications.
The heavy-duty 2120 series, also with multidirectional
steering, is characterised by its robust design and high
load capacities. With its large-sized Vulkollan (PU) tyres,
these are mainly used indoors or in canopied outdoor
areas.
Order Picking
HUBTEX picking trucks are based on a conventional
multidirectional sideloader or the more specialized
platform configuration.
The MU-OP one-man and MU-SO one and two-man order
picking trucks are used for picking long loads. They are
specially made for aluminium, plastic or steel profiles and
for order picking in narrow aisles.

Eco Timber Traders offer one-on-one assistance and advice
and will advise you on what specie of timber would be best
suited to your application and will then help you select the
best planks for the job.
Their machine shop can surface, rip and plane your planks to
your preferred specification, as well as laminate and sand
your tops if required.
They can also plane your bundles down to your exact
finished size and cross cut your components.
They are also able to run basic mouldings for skirtings,
architraves, flooring and ceiling boards, and this can be done
with the wood of your choice.
Timber identification:
There are very few places in the country where one can get
timber identified. Timber identification can be done by
visual inspection where the sample of wood in question is
inspected for colour, grain figure, weight and even smell.
Most of the time if it’s a wood that Eco Timber Traders is
familiar with, it can be identified straight away. If the timber
cannot be visually identified, a sample will be sent away to a
lab where the cell structure is carefully examined under a
microscope by a professor of wood science.
Giving back
In an effort to give something back to the forests from which
we earn a living, Eco Timber Traders has initiated a scheme
whereby on request, indigenous trees are given away for
every sale of wood that is over 1m3.

Regulating the manufacturing and
erection of timber roof structures
Roof trusses come in all shapes and sizes to suit every roof design, and constitute
the large timber members that comprise the framework of the roof, providing a
structural base for the installation of the roof covering material.
T
he main members of the roof structure are referred
to as the rafters, tie beams and the webs. Timber
trusses are either prefabricated or manufactured
on site by a specialist carpenter. Site manufactured
roof trusses are bound to comply with the deemed-tosatisfy requirements of SANS 10400 (Part L), which does
not cater for complex roofing solutions. The architect’s
design of the roof will determine the truss design and
depends on factors such as the intended pitch of the roof,
configuration of the house and whether or not the internal
walls are load-bearing. When the builder has erected the
scaffolding, the roof trusses are hauled up onto the top of
the walls and are then firmly fixed onto wall plates with
metal anchors/ties that have been pre-built into the
brickwork.
Role of the Institute for Timber
Construction
The Institute for Timber Construction South Africa (ITC-SA)
is an industry body geared to informing and educating
54
AUGUST 2012 //
building contractors about this integral component of the
roofing structure, while equipping homeowners with
information that can affect the building of their homes.
The ITC-SA conducts ongoing research and development to
ensure that the design, manufacture and erection of
prefabricated nail-plated timber trusses are carried out in
accordance with set industry standards.
To enable this, the ITC-SA liaises closely with the South
African Bureau of Standards (SABS), the National Home
Builder Registration Council, the National Regulator for
Compulsory Specifications, the South African Timber
Auditing Services (SATAS), the Engineering Council of
South Africa (ECSA) and the four leading nail plate system
providers, Mitek Industries, Alpine Automation SA, and
Multinail Africa and International Truss Systems, which
supply fabricators with engineering software for the
design and manufacturing of rationally designed timber
roof structures.
itc
Erectors:
On the operational front, the ITC-SA has established
regional branches in the Western Cape, South/Eastern
Cape, OFS, Polokwane, Mpumalanga and KwaZulu-Natal,
all of which are operating successfully.
To regulate the application of structural timber, the ITC-SA
is involved in the following activities:
•Acquiring the necessary skills in the field of timber
engineering from international sources, or through
research, so as to develop reliable codes of practice.
•Research and updating of bracing and connection rules
through the Timber Engineering Advisory Committee,
and the publication of erectors’ and designers’
handbooks to disseminate information to the market
place.
•Arranging awareness seminars on the erection and
bracing procedures for engineers, architects, clerks of
works, building inspectors, builders and carpenters.
•Encouraging the removal of barriers for the acceptance
of timber structures by local authorities, government
agencies, lending institutions and professional groups.
•Working to establish the availability of appropriate
grades, sizes and quality timber that will ensure safe and
economical timber structures.
•Providing the expertise to answer technical enquiries
effectively and to investigate problem structures
impartially, or to act on complaints from customers or
fabricators in an unbiased and fair manner.
Engineers:
ITC-SA acknowledges engineers with extensive experience
and proven competence in timber engineering by
accepting them as Accredited Engineer Members. To
ensure full compliance with all the provisions of the
Building Standards Act and National Building Regulations,
these engineers may inspect and sign off rationally
designed and erected timber roof structures.
Bracing and connection rules for timber roof structures are
researched and updated. Awareness is created through
seminars and presentations to disseminate information
and amendments on specifications and regulations to
industry role players and to educate erectors where
possible. The Institute has developed two volumes for the
erection of timber roof structures. The Roof Erectors
Handbook Volumes One and Two have been revised and
updated to include changes in SANS 10243, and are
available from the ITC-SA offices.
The ITC-SA co-ordinates an infrastructure of professional
roof inspectors, who operate under delegated authority
from the ITC-SA Accredited Engineers. These accredited
inspectors are able to inspect the timber roof structure for
compliance with the National Building Regulations, so that
homeowners can obtain an occupancy certificate from the
local authority.
Training:
The ITC-SA constantly evaluates the performance and
skills of its members, and to enhance industry capabilities,
presents courses and provides information that will assist
members and non-members in adhering to standards.
Membership benefits:
The ITC-SA and its members are key role players in the
timber roof truss industry. The Institute provides an
opportunity for everyone associated with it to participate
and shape the future of the industry through knowledge
and expertise, so as to continuously update and review
regulations and specifications.
The ITC-SA believes in an industry working in unison to
promote a common interest and which will produce results
more effectively than individuals working separately. Also,
a unified Institute has more authority than individuals, and
can ensure that the industry follows and complies with the
norms and standards that have been developed in
consultation with industry stakeholders and which will
allow for proper regulation.
Institute for Timber Construction
South Africa
Fabricators:
To ensure compliance with industry standards, licensed
fabricators are audited for the awarding of a Certificate of
Competence. This certificate confirms competence and
quality in the manufacturing and supply of pre-fabricated
nail plated timber trusses. The ITC-SA also runs courses for
estimators and designers, and strives to continuously
upgrade the quality and competency of personnel in truss
plants.

Lonza's Tanalised™ Treated
Pole Seminar Raises
Awareness about Quality
Treated Poles in Zimbabwe
Lonza Wood Protection, (Arch Wood Protection acquired by Lonza in
2011), has taken the initiative and set the bar in raising awareness about
the importance of quality preservative treated poles in Zimbabwe.
T
he Tanalised™ Pole Seminar, recently hosted by
Lonza in Harare, received an overwhelmingly
positive response from local pole treaters, power
and telecommunication utility companies, as well
as representatives from the Zimbabwe Standards
Association and Government and the Botswana Standards
group.
“Our main objective was to create an education platform
to provide the various end-users in Zimbabwe with a
broad understanding of the importance of timber
preservation and, in particular, the benefits of Tanalised™
wood preservative treated poles. Our speaker line-up
comprised experienced professionals who were qualified
to empower the attendees with knowledge in the field of
timber preservation, quality issues and National
Standards,” said Gerard Busse, Marketing Manager, Lonza
Wood Protection.
The emerging creosote shortage brought the benefits and
growing demand for Tanalised™ wood preservative
treated poles under the spotlight as one of the main topics
of the seminar. Darren Marillier, Sales Manager at Lonza
Wood Protection, presented the numerous benefits of
treating with Tanalith™C wood preservative with
Weatherwood™ water repellent additive across all utility,
agricultural, building and fencing pole requirements. In
particular, the excellent fungal performance, stability of
the wood preservative in the treated timber, quality
control and transport cost benefits were highlighted.
Darren added that Tanalith™C wood preservative has
grown in popularity throughout Africa in part because it
fully penetrates the sapwood of eucalyptus transmission
poles through a chemical bonding to the wood cells. He
explained that the Full-Cell Tanalised™ treatment process
ensures full sapwood penetration more readily than the
treatment processes used with other wood preservatives.
Darren closed by underlining the proven track record of
Lonza and Tanalised™ wood preservative treated poles,
including Lonza’s reputable ISO standard rating and full
client technical support.
Guest speakers, Bruce
Breedt - Executive
Director of the South
African Wood Preservers
Association and Philip
Boardman - owner of
Alternative Structures,
shared their wealth of
industry knowledge that
covered the basics of
wood preservation to the
importance of quality in
the treatment of poles.
Other important aspects
covered included product
certification systems and
the preparation of
treated poles for the endmarket by adding value
through the identification and application of anti-split
plates to treated poles. Both Breedt and Boardman agreed
that the seminar presented a ‘win-win’ situation, as they
were grateful for the opportunity and platform to raise
awareness about the need for quality preservative treated
poles.
To bring ‘local flavour’ to the seminar, Maxwell Nyanungo
of Standards Association of Zimbabwe, discussed product
certification to the Zimbabwe timber industry. The topic
was well received and led to an in-depth discussion with
many questions being raised and clarified.
In conclusion, Doug Sayce, General Manager of Lonza
Wood Protection, expressed his confidence that the
objectives of the seminar had been met by saying, “The
positive response to the seminar from a very strong
contingent of industry and government role players has
been encouraging for us. I believe that our objective of
highlighting the quality cycle of preservative treated
poles was well addressed and well received.”

CIFOR
REDD+
as an idea is a success but implementing it is
fraught with challenges, new global study says.
Photographs: CIFOR
I
mplementation of a UN-backed scheme that aims to
reduce greenhouse gas emissions by protecting
tropical forests is fraught with challenges, but these
can be overcome with technical solutions and
increased political will, according to the authors of a new
publication from the Center for International Forestry
Research (CIFOR).
Analysing REDD+: Challenges and Choices, released on the
side-lines of the Rio +20 summit, reports on the current
state of REDD+, which stands for Reducing Emissions from
Deforestation and forest Degradation, as well as the
conservation and sustainable management of forests, and
the enhancement of forest carbon stocks.
The study, drawing on three years of research across Asia,
Africa and Latin America, offers fresh insights into the
challenges faced by REDD+, and suggests new ways of
addressing some of them.
“There are a lot of practical challenges, but this book
shows there are workable, technical solutions to these, so
the main problems are really the political ones,” says Arild
Angelsen, an environmental economist with CIFOR and
professor at the Norwegian University of Life Sciences,
and the book's main editor.
“You cannot address climate change without including
REDD+.”
Seven years since the idea of reducing emissions through
avoided deforestation was launched, the publication takes
58
AUGUST 2012 //
a critical look at REDD+, asking how it has changed, how it
is unfolding in specific national policy arenas – and
highlighting the choices for making REDD+ more effective,
efficient, and equitable.
“REDD+ as an idea is a success story,” says Angelsen. “It
was something genuinely new, and the new key element
was that it was based on payments for performance or
results. And it was also to be accompanied by big money.”
“We compare it to 'sustainable development' – a nice catch
phrase and promising to do a lot. Both ideas have been an
inspiration for policy makers and practitioners.”
But as REDD+ has moved from an idea into the real world,
the difficulties have mounted. Those challenges are both
practical and political. They range from how to measure
and monitor the carbon emissions avoided by leaving a
forest standing, to deciding who should get the money
generated by REDD+, to achieving coordination among
local, regional, national and international levels of
governance.
“REDD+ design and implementation is extremely
challenging,” says Angelsen. “The devil is in the detail –
when you start to work out the specifics of REDD+ then
there is more conflict.”
An emerging problem for REDD+ is how to develop
reference levels, in order to provide a benchmark to
measure the impact of the scheme in the form of reduced
or avoided emissions.
CIFOR

To make payments based on results, REDD+ needs a standardised
mechanism to measure how much carbon would have been released,
had a forest been destroyed or degraded rather than protected.
©CIFOR
This is a difficult task – facing a lack of data, high uncertainty about
predicting deforestation rates in the future, and strong incentives for
biased estimates.
Analysing REDD+, which was published as part of CIFOR’s Global
Comparative Study on REDD+, presents a new, step-wise approach to
developing reference levels at the national level, which would allow
all countries to build these all-important reference levels, even if
they have low levels of institutional capacity and ability to collect
data.
The book also reveals some encouraging news regarding the location
of REDD+ pilot projects. The success of REDD+ in actually reducing
carbon emissions depends on interventions happening in areas of
high deforestation.
Analysing REDD+'s detailed study of project locations in Brazil and
Indonesia finds that REDD+ projects are more likely to be established
in areas with high deforestation rates and high forest carbon
densities – suggesting the projects have the potential to make an
impact.
In the book’s concluding chapter, Angelsen and CIFOR Director
General Frances Seymour say there is much uncertainty about REDD+,
but this should not lead to inaction. They say there exist 'no-regrets'
actions that should be put in place immediately and that represent
good public policy even if they do not eventually generate emissions
reductions. These include clarifying land tenure, removing perverse
subsidies, and improving access to forest-related data, as well as
improving institutional capacity and law enforcement.
However, Angelsen says REDD+'s primary goal should still be the
reduction of carbon emissions.
“There is a high risk of harmful climate change, and we should do
something about that, and REDD+ is a key part of what we should do,”
Angelsen says. “It's not simple, but still, REDD+ is easier and cheaper
than a lot of other mitigation efforts. So I think there are still things
to be excited about when it comes to REDD+.”
The Center for International Forestry Research (CIFOR) advances
human wellbeing, environmental conservation and equity by
conducting research to inform policies and practices that affect
forests in developing countries. CIFOR helps ensure that decisionmaking that affects forests is based on solid science and principles of
good governance, and reflects the perspectives of developing
countries and forest-dependent people. CIFOR is one of 15 centres
within the CGIAR.

Clamping down with
the Eclipse range of
quality consumables
for professionals and
DIY enthusiasts
Quality in tools is very important to the
engineering, woodworking and DIY industries.
An investment in reliable and trustworthy
brands pays dividends by increasing the
longevity of the tool, increasing productivity
and enhancing product quality.
F
irst Cut, a reputable and experienced distributor of
international capital equipment and consumables,
seeks solutions for its customers that are not only
application-specific but that will stand the test of time.
“Eclipse manufactures a wide range of high quality
G-clamps, one-handed bar clamps, sash clamps and vices
that are geared towards our discerning customer base,”
says First Cut Sales Director, Gary Willis.
With a national network of branches in Johannesburg,
Cape Town, Durban and Port Elizabeth, First Cut is able to
provide customers with expert advice, 24-hour delivery
service, superior technical support and a product range
that has been selected for a best-practice customer
experience.
“A differentiating factor with Eclipse tools is that even
though they are of a high enough specification to be
utilised in the demanding areas of both engineering and
woodworking, where there is no room for error, they are
still affordable enough for DIY enthusiasts,” says Willis.
“This obviously has direct benefits for the DIY sector, since
they are able to leverage the research and development
that has gone into these precision tools, at a price that will
not break the budget.”
The Eclipse range of G-clamps comprises an unbreakable
malleable cast iron frame that ensures any downtime, due
to product failure, is eliminated. In addition the tommy bar,
incorporated into the design, bends before the frame can
become over-stressed. “These clamps are so reliable that
there have been absolutely no product returns since their
launch two years ago,” says Willis.
62
AUGUST 2012 //
The steel swivel shoe applies consistent clamping
pressure, even on angled surfaces, and the fast two-start
rolled acme thread ensures quick opening and closing of
the clamp. The G-clamps are available in six sizes: 75, 100,
150, 200, 250 and 300mm.
“The one-handed bar clamps, with quick release trigger,
enable the user to have one hand free to hold the
workpiece.
This is a great addition for DIY and woodworking
enthusiasts who need to clamp or spread the workpiece,”
says Willis. Available in five sizes from 150 up to 900mm,
the one-handed bar clamps have a slight toe-in at the top
to improve clamping pressure and are capable of 150kg
clamping force. Durability is provided by the reinforced
nylon body and carbon steel bar.
Eclipse mechanic’s vices are precision-milled to ensure
fast and smooth operation. The body and sliding jaw are
manufactured from high-quality cast iron, which has
excellent shock absorbing characteristics. The full range of
five different sizes, from 75 to 200mm, can be benchmounted or mounted on optional swivel bases, dependent
on the application. “These vices are really cost-effective,
since the steel serrated jaws can be replaced when worn,”
says Willis.
Designed for the woodworking market, the quick release
woodworker’s vices open and close without the use of the
main screw. “These products, as well as a number of other
new releases from Eclipse, offer our current and potential
customers all the benefits of high-end tools, without the
accompanying high price,” Willis concludes.
