Transcript: Brisbane Flood Resilient and Accessible Ferry Terminals Design Critical transport infrastructure in Brisbane was devastated when the river flooded in January twenty eleven. The Aurecon and Cox Architecture team was passionate about finding a better way to make this critical ferry infrastructure more flood resilient, accessible and for travellers to enjoy and celebrate the river. These new generation ferry terminals stretch conventional boundaries. They incorporate world leading flood resilient technology which means the terminal can be returned to operation shortly after a flood event. A single sculpted pier allows commuters to enjoy panoramic views of the Brisbane River. It deflects debris away from the pontoon while also providing primary restraint of the pontoon. And upstream fender absorbs flood impact and deflects objects to prevent damage. During a flood, the gangway uses the floodwaters to become buoyant and automatically detach from the shore; swinging behind the pontoon and out of the way of debris. The mooring point changes function to provide a supplementary lateral restraint to the pontoon. The downstream arm pivots below the water line. A chain connected to an underwater pile secures the downstream arm. The pontoon’s boat shaped hull makes it more resilient by minimising flood drag force. Believed to be a world first for compliant disabled access, the unique gangway mechanics maintain level intermediate landings throughout the tidal range. An innovative hanging floor within the gangway structure uses pinned parallelogram frames which can rotate and are connected to fixed triangular frames that maintain their installed level regardless of how the internal structure moves. Now everyone is able to enjoy the iconic Brisbane Ferry Terminals and commuters and the city will benefit from resilient terminals that can quickly return to use after a flood.
