This project identifies drivers for, and barriers to, the increased use of prefabricated timber building (PTB) systems in Class 2 to 9 commercial buildings, such as apartments, hotels, office buildings and schools.
PTB systems in Australia are in a formative stage and yet to achieve broad acceptance in the marketplace as a conventional method of building.
Opportunities for PTB systems can use timber’s well-established benefits such as high strength-to-weight ratio; design and construction flexibility; general environmental credentials including carbon sequestration; and prefabrication’s suitability for use on brown-field, restricted access and difficult sites and developments. In addition legislative constraints have now been largely removed (e.g. through changes to the 2016 National Construction Code).
An increase in large scale mid-rise prefabricated buildings, and with the increasing nationalisation and internationalisation of the top tier building companies, suggests market acceptance will grow as PTB buildings are seen as ‘normal’.
Wood frame construction in China is currently limited to 3-storey buildings, mainly due to fire risk perceptions. However, multi-storey (more than 3 storeys) wood frame buildings are gaining popularity around the globe, while providing an acceptable level of performance in...
At present in Chile it is not possible to construct buildings higher than 3 storeys using timber as structural material. This difficulty is due to high demands of regulations, in addition to cultural reasons, even though there are buildings in timber with more than 5 storeys built in 1910...
Recent changes to the National Building Code of Canada (NBC), and a trend towards more diversified housing options, have meant that many Canadian jurisdictions are acting quickly to capture the environmental, economic and social benefits of higher wood buildings. The 2015 NBC now permits wood frame construction to be 6 storeys high. Today, already 75% of Canadians live in jurisdictions that allow 6 storey wood frame construction. With the overall benefits of using wood as a building material well documented, Atlantic WoodWORKS!
studied the opportunities for 6 storey wood construction in Atlantic Canadian Centres. The research included a comprehensive market study and projections for mid-rise demand in
four major centres in Atlantic Canada, a review of recent and upcoming planning changes in major Atlantic Canadian cities and a full cost analysis, comparing wood construction to three
other construction methods in use in the Atlantic market using a real-life wood mid-rise structure built by an experienced builder.
