Beginning with extensive investigation of site specific ground conditions, 20 Customhouse Quay has been designed from the ground up to provide maximum safety and resilience for you and your team, both during an earthquake and in the aftermath. While human safety is paramount, business continuity has also been prioritised to minimise disruption.

Base isolation, a technology akin to a suspension system that isolates the building from ground movement, substantially reduces the forces that an earthquake can exert on the building. The diagonally braced diagrid perimeter columns support the base isolation with a significantly stiffer tower frame. Together these technologies offer seismic performance far in excess of building code requirements. They also considerably reduce the movement experienced in the building during an earthquake which reduces the danger from falling objects such as furniture and equipment.

20 Customhouse Quay has been designed close to Importance Level 4 for seismic performance.  The building code only requires office buildings to meet Importance Level 2. 20 Customhouse Quay has been designed to survive a 1 in 500 year earthquake with no structural damage (versus 1 in 25 for a 100% NBS building) and to protect lives in a much more severe event.

The building will have a backup generator for 100% of on-floor power and life safety systems in case of power interruption, and a dual sprinkler supply in case of water supply interruption. Essential electrical services will be physically elevated to protect the building operations from flood or tsunami risk.

20 Customhouse Quay represents a new generation of office safety and resilience.
