TAFE Timber Education Newsletter 2008 #3 |
|
|
|
4-December-2008
Welcome to the third TAFE timber education newsletter for 2008.
|
|
Welcome to our special Christmas edition of the TAFE Timber Education newsletter for 2008.
I hope this newsletter finds all in good spirits and we look forward to keeping you all up to date throughout 2009.
I have visited a number TAFEs over the last couple of months to introduce myself, go through our recently
produced (and older) resources and get feedback. The feedback has been invaluable and I've been able to
get a better understanding of your needs. If I haven't got around to your college or campus yet, I hope
to see you in the New Year.

Urgent Feedback - AS 1684 Revision
The Australian Standards Committee TM - 002 will be meeting on the 10th and 11th December 2008 to commence
the extensive detailed technical revision to AS 1684 Parts 2 to 4. It has been well over 3 years since
any technical work has been done to the Standard so there is a big backlog of issues to address including
the outcomes from the R&D projects on simplified tie-down for high winds, nogging requirements and
inclusion of building practices for engineered wood products.
If you have any technical or clarification issues with AS 1684, NOW IS YOUR CHANCE to have these
considered in the revisions.
Simply describe and detail your issue or proposed changes and email them to the TM-002 Project Manager

Corrections - Timber Stairs, Balustrades and Handrails Manual
The maximum housing depth into a string allowed is 10mm, not 15mm as is written on pages 22 and 23 of
the new manual. The correct maximum 10mm housing depth to accommodate treads is included in Table 4-3.
Also, the Table 4-1 Suitable Species should be ticks instead of the number 3. Something happened with the printer!
The online edition of the Manual (available at
www.timber.org.au)
will be updated very soon to correct these errors and the print copy updated in the next reprint.

Wood Naturally Better - New Industry Campaign
October 8th in Melbourne saw Forest & Wood Product Australia officially launch the new
Wood Naturally Better campaign on behalf of the Australian Timber industry.
Wood Naturally Better has been developed, in line with other world wide timber initiatives,
to show how using timber can play a part in tackling climate change. The promotional programme
is designed to target both professionals and consumers and will comprise of advertising and national
activities to get the message out to the very broad Australian community.
This campaign will run for the next 5 years and will, in this implementation stage,
concentrate on the environmental benefits of wood. Wood stores carbon, a well known but
little understood fact, which will be the focus of the early advertising material. See the
website at
www.naturallybetter.com.au.

Inspiration - World's Tallest Modern Timber Building
Here's a bit of inspiration. On a recent holiday to the United Kingdom, Timber Development Association's
Andrew Dunn was taken along to the northern London suburb of Hackney, where he had the opportunity to
see first hand the world's tallest modern timber building under construction.
The building is comprised of 29 apartments on 9 floors, and is constructed with cross laminated solid timber panels.
These panels are used for load bearing walls, floors, stairs and the lift cores. The structure was completed,
by a crew of 5, in nine weeks, much quicker than other more conventional methods.
The idea for this timber residential tower in the northern London suburb of Hackney, came about as a
result of the City of London's planning requirement which requires a 10 per cent reduction in carbon
emission through on-site renewable energy generation.
The building was conceived by Architect, Andrew Waugh, who saw that by storing carbon in the building
as wood he could more than just meet the city requirements without the need of a costly on-site generation plant.
In keeping with the current world trend toward the use of wood as a carbon storage, Andrew and his
team calculated that the 9 storey residential building could store 181 tonnes of carbon when completed
and by not using traditional concrete methods could save a further 125 tonnes from entering the
atmosphere during the construction process.
Although the actual panelised cross-laminated timber product was not readily available in Australia
at this time, there's no reason that given the right lead time this or some similar product could
certainly be made available. For more details with product procurement, technical information and
design detailing contact TDA on 02 9279 2366 or by email to

New Long Span Timber Beams Resource
A
new resource
has recently been added to the revamped
www.timber.net.au
website to help the
correct use of engineered timber supporting beams. Timber supporting beams are cheaper, safer
and easier to implement than their steel alternatives. Their popularity has been somewhat
limited, however, by a lack of publicly available information on how best to incorporate
timber beams into building design. Our new resource aims to correct this.
The
online resource
addresses the issues most critical to builders and designers. It outlines,
crucially, the advantages of engineered timber beams over steel beams - and provides an image
gallery which makes clear the considerable aesthetic advantages of timber supporting beams.
Different types of long span timber beams are listed together with the scenarios in which they
are typically used. Design strategies for the implementation of long span timber beams are also
considered, and means of selecting and procuring the beams are outlined.
This new resource is available both as an
online resource
and as a
downloadable document
(PDF, 2.7 MB).
Development of the resource was funded by Forest & Wood Products Australia.

New Plywood Box Beam Span Tables
Plywood box beams are lightweight, simple to fabricate, conventionally stable and, with good design,
structurally efficient and economical. Provided in this resource are span tables designed according
to limit state design theory and for winds speeds up to N3 as well as installation notes. The span
tables open up new options for beams incorporated into walls, portal frames and other typical long
span applications.
This resource is available as a
downloadable document
(PDF, 5 MB). Development of the document was
funded by Forest & Wood Products Australia.

Even More Educational Resources
Just a reminder that the web site
www.timber.net.au
has a large range of resources for use in education relating to the use of timber in buildings.
Teaching Resources - information for teachers including downloadable PowerPoint
presentations on applications, properties, production, AS1684, multi-residential
timber framing, cladding as well as timber stairs manual.
Learning Resources - information for students including applications, properties,
production, durability, specifications, manufactured wood products, connections as
well as 18 case studies of timber in use.
Reference Resources - for teachers and students including timber flooring (installation guide),
timber construction in bushfire prone areas through to structural timber design guides.
The following educational resources are available through the Timber Development Association at no or small
cost. We also have a more extensive list of publications available from our website,
www.timber.net.au, which may aid your teaching.
Timber in Australia in Colour
The first full length, illustrated study of
timbers which are available in Australia - on DVD. Recommended retail price: $50.
Acceptable Standards of Domestic Construction
This excellent resource has been revised to address the most recent developments in construction and timber
design. The recommended retail price is $25. For bulk purchases of one box (30 books) we are offering the books at the reseller price.
Australian Hardwood and Cypress Manual
The Hardwood and Cypress manual is a must have for all specifiers and for anyone teaching timber
related subjects. The Manual is split into four sections: an introduction, a technical and detailing
guide, a set of species guides, and application guides. It is available for free download from
www.timber.net.au.
