This is one “big” shed being built in Australia, it is taking shape at Toowong in Brisbane’s west. The six-storey-high, 89m long shed is being built at the Legacy Way tunnel worksite.
Lord Mayor Graham Quirk said the shed would house the tunnel boring machines and shield motorists and residents from noise and dust.
Cr Quirk said the acoustic shed made of Colorbond steel and measuring 89m long, 77m wide and 29m high would be a temporary feature beside the Western Freeway.
It will be taken down late next year when the tunnel is completed.
“The acoustic shed is made with more than 1000 tonnes of structural steel, and in terms of floor space, is nearly 500 times bigger than your average backyard tool shed, so it’s no small feat to construct,” he said.
The tunnel boring machines (or TBMs) would operate 24 hours.
When completed the acoustic shed will be fitted with a series of travelling cranes, which will be used to assemble the two Tunnel Boring Machines.
