Special Feature Forté in Melbourne, Australia. Timber high-rise: not an inferno Contrary to popular belief, timber performs much better in a fire compared with concrete and steel. (Contributed by Malaysian Timber Council) THOUGH WOOD HAS been used for light timber framing in low-rise buildings for over a century, the use of wood in construction has yet to reach its true potential. Most builders tend to opt for steel or concrete framing, especially for high-rise buildings, due to the myths surrounding the integrity and performance of timber during a fire. Wood is often misconstrued as being structurally less sound than concrete or steel as well as more prone to fires. The advancement of fire-proofing technology and the emergence of modern engineered timber composites in the past decade such as laminated veneer lumber (LVL), laminated strand lumber (LSL), The charred beam from the mall in Salem, Oregon. 36 Building & Investment | www.b-i.biz glued laminated timber (glulam) and cross laminated timber (CLT), have opened the door for wood to be used as the primary building material in larger and taller buildings. In many European countries, prefabricated timber is widely used in the construction of high-rise buildings. It has been proven that the technical strength of engineered timber such as CLT is similar to that of pre-cast concrete. Pioneering the way forward for highrise timber buildings is the 10-storey Forté in Melbourne, Australia. Considered the world’s tallest contemporary timber building, Forté used predominantly CLT in its construction and successfully reduced its carbon footprint by 1,451 tonnes. The use of CLT in the UK has grown tremendously in the past decade across all building sectors, as more architects, contractors and developers see the sustainable and practical benefits that it offers.
