These presentations were delivered on November 25, 2019 at the WoodSolutions seminar at 25 King St, Bowen Hills
The pace of change in timber technology, manufacture and construction globally is staggering. Timber, the material which dominates Australia’s residential framed construction, is now firmly embedding itself in the mid-rise construction market; the 2019 NCC has also now expanded the mid-rise timber Deemed-to-Satisfy provisions to all classes of building - creating more new market opportunities.
To meet these emerging opportunities innovations are needed in manufacture, supply, design and construction. In this comprehensive and structured half-day seminar, leading timber industry and building professional experts presented the latest knowledge and innovations, covering the wide range of timber building system solutions now available, across all building classes, including: lightweight timber-framing, heavy timber Glulam post and beam, and massive timber panels such as laminated veneer lumber (LVL) and cross laminated timber (CLT) and the existing and evolving new methods of off-site manufacture, prefabrication and supply.
Exciting case studies of recent and upcoming mid-rise timber projects were presented, by key project personnel.

Simon Betteridge and Jordan Price present a case study of Monterey Apartments.
One of the key drivers for timber was weight. The Clem 7 tunnel is below the site and the maximum height of a concrete structure would have been 4-5 storeys. The timber in the structure weighs approximately 790t, the equivalent in concrete is approximately 3,270t.

Toby Hodson presents a range of Arup projects, in Australia and internationally, that feature the use of timber building systems.
Conclusions:
Engineered timber is useful for many applications
It is not just about timber – be clear on how material furthers project aims
It is not just about large commercial projects – innovate at small scale
There are great opportunities – focus on manufacturing and assembly to
maximise benefits
WoodSolutions and suppliers are an excellent resource – collaborate well
Timber is nothing new – it deserves to be a tool in your toolbox
Paolo Lavisci, Program Development Manager with the WoodSolutions Mid-rise Advisory Team, presents the case that with timber building systems safety, speed and quality can all be achieved.
Laurence Ritchie, Cost and Program Estimator with the WoodSolutions Mid-rise Advisory Team, demonstrates the value proposotion of timber construction systems, with case studies and worked examples.
Trent Kennedy, Rider Levett Bucknall, presents a case study of cost planning an 8 level apartment building.
Adam Jones, Engineering Advisor with the WoodSolutions Mid-rise Advisory Team, uses three projects to demonstrate the advantages of designing for timber, rather than repurposing a concrete design.
