The world’s tallest building spire, at 97.7 metres and weighing 110 tonnes

SPIRE

The spire, a purpose-built lightning rod, is designed to draw lightning away from

the structure and down to dissipate the voltage.

During recent Queensland storms, the spire was hit eight times by lightning bolts.

TECHNOLOGY

• The key design criteria for the Q1 tower’s concrete requirements was to

provide an innovative concrete solution to ensure the concrete could be

pumped to great heights.

• 61,000 cubic meters of concrete used in the entire process.
