NINE-thousand cans and bound only by their imaginations, engineers from leading industry groups yesterday participated in Gladstone's first Canstruction global design and build competition.
The Gladstone Entertainment and Convention Centre was transformed into an engineering mecca, where the teams displayed their impressive creations.
From cranes to whales and even a giant puppy, the canned structures reaped bewildered responses from passing crowds.
Mel Case, community relations manager for Bechtel, said the six teams had delivered beyond expectations.
"This is the first time Canstruction has been held in a regional centre, and it has been a great effort from everyone," she said.
"A total of 9000 cans have been used in the displays, which will all be donated to the RSPCA.
"There a lot of tails wagging in Gladstone at the moment."
Jo Winters, team leader of the QCLNG display, said the hardest part of the project was transporting the cans.
"It's been great fun," she said. "The hardest part was getting the cans out of the car and picking the right colours."
The largest display of the day was "Curtis CANine", a giant puppy, requiring three hours work from each of the seven team members, and 2000 cans.
The Santos team showcased its impressive blue whale, consisting of 1500 blue cans, replicating Earth's largest mammal.
The winning entry of the day went to Queensland Alumina Limited team, whic elected to sculpt a single droplet of freshwater foregrounding a map of Australia, made of 2236 cans of pet food and weighing a whopping 610kg.
Team members Teagan Walsh, Janis Barker, Richard Furness, Alex Neilson, Martin O'Driscoll, Carmen Smith and Daniel Tu hoped to relay the importance of water in Australia, and in the field of engineering.
"Engineers play a lead role in the design, construction and operation of water-saving projects across Australia," they agreed.
"Everyday in industries and communities across Australia, engineers work in the supply, re-use and conservation of water."
