World’s tallest engineered timber office building
The Brisbane Showgrounds is set to house the world’s largest and tallest engineered timber building at 25 King Street. The first delivery of cross laminated timber (CLT) columns, beams and floor panels arrived at the grounds in February 2018 for construction.
General manager for Lendlease Building, Tony Orazio says construction of 25 King was well underway with the installation of the first pre-assembled modules taking place.
“As the world’s largest and tallest engineered timber office building, 25 King will be one of the most exciting additions ever made to Brisbane’s skyline.
“A key element of 25 King’s structure is the use of prefabricated modules for each floor. These modules are pre-assembled at ground height and then lifted into place to form what looks like a wooden lego structure,” says Orazio.
“The fascinating thing about building with timber is that its strength is akin to concrete and steel, it can be produced economically in a factory environment and most importantly boasts a plethora of sustainability benefits.”
A world first in sustainable architecture, 25 King is targeting a 6-star Green Star Design and As Built rating which will use 67 percent less electricity and 55 percent less potable water (than industry standard benchmarks) and is targeting a WELL Core and Shell rating.
At a height of almost 45 metres, the ground plus nine-storey Bates Smart-designed tower includes services provided by global engineering firm Aurecon as well as three bespoke retail tenancies. Owned by Impact Investment Group the innovative building will also be the future home of Aurecon, with the company committing to lease four of the nine office floors.
25 King will see six storeys above ground by mid-2018 and is due for completion in late 2018, with Lendlease developing and building the asset. Lendlease will continue to work with its partners to lease the approximately 7900 square metres of remaining office space.
25 King is Lendlease’s fifth engineered timber building in Australia and joins International House Sydney, Forte Apartments and Library at The Dock in Melbourne, and Jordan Springs Community Hub in Western Sydney.
Lendlease is a partner in The Future Timber Hub, Australia’s leading timber research collaboration committed to challenging the barrier of timber construction by pursuing research-based strategies and innovation technologies to boost the timber industry.
25 King project facts:
25 King is comprised of 3097 individual timber elements, 33 timber columns on each floor and 52 beams, CLT (approximately 21,175 square metres or 4824 cubic metres of CLT timber [walls and floor]), and glulam (approximately 1415 cubic metres [beam and columns]).
Approximately 112,500 screws/bolts are required for the construction of 25 King, and six core modules and six K bracing modules to assemble per level. The project team has allowed two days to pre-assemble the modules in each floor cycle.
A spruce tree is an exceptionally fast-growing species found in Austria, and the time it will take to grow back the timber used on 25 King is as little as six hours in total.
