Adelaide Convention Centre will soon be home to the world’s largest rotating seating drums.

The two 18 metre revolving drums, that each accommodate seating for 320 each, can rotate 180 degrees in minutes, and will be used to quickly reconfigure conference and event space within the East Building Plenary.

It took a team of 20, around 26 weeks to construct and install the seating drums.

The East Building will also feature a new auditorium with hinged seating stored in the roof space, which can be easily lowered to convert from exhibition space to lecture theatre style space.

The Drums and hinged seating work in tandem with fully operable sliding walls, which can be put into place to enclose conference space, or be retracted to open up the Plenary to full capacity.

The Plenary will allow numerous possible reconfigurations of the space to suit the requirements of each event with options for tiered or flat floor.

The East Building will be able to be subdivided and configured within minutes as pre-function space, ballroom, exhibition or plenary. Each meeting room will be serviced by individual lighting and audio systems.

Adelaide Convention Centre Chief Executive Alec Gilbert said the new East Building is the final stage in creating Australia’s most flexible convention centre.

“New technologies are the hallmark of the $400 million expansion which will set a new benchmark in convention centre design and functionality,” said Gilbert.

The new East Building is on-track to open in 2017.
