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

28. 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

29. • 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.
