Four Buoyant Flap Gates have been specifically designed to manage flood water through Pacific Fair’s underground shopping centre car park.
Originally a floodplain, the site is prone to flood inundation.
The Scentre Group approached AWMA to design a flood management system that would autonomously allow the retention of up to 600mm floodwater in the basement before isolating the structure from further inundation.
AWMA’s design team developed the innovative Buoyant Flap Gate which automatically closes as the water within the basement rises. Once flood levels reach the nominated depth, the gates are in the fully closed position, thereby preventing further ingress of floodwater.
