Suncorp Stadium is now a closer resemblance to its famous nickname of the 'Cauldron' after its redevelopment reached a significant milestone - the completion of the seamless roof.

The Deputy Premier and Minister for Sport, Mr Terry Mackenroth and Minister for Public Works and Housing, Mr Robert Schwarten, joined Managing Director of Castlemaine Perkins, Mr Ken Freer, for a ceremony to acknowledge the major construction achievement.

Mr Schwarten said workers on-site today earned a break at the nearby fourex Breweries as part of the ceremony.

He said the highest part of the stadium was now completed with the last roof panels installed. "The roof will cover 75 percent of the 52,500-seat capacity," Mr Schwarten said.

"Its installation was a very difficult procedure that presented many challenges.

"It weighs a total of 2,750 tonnes and is supported by buttresses on the four corners. The largest roof piece to be lifted weighed 200 tonnes.

"I congratulate each and every worker on-site for this wonderful milestone which will, no doubt, help ensure Suncorp Stadium is a 'cauldron' in every sense of the word.

"I'm sure workers associated with this landmark project will remember their involvement in building the stadium for the rest of their lives."

There have been more than 850 workers involved in the project ranging from electricians and plumbers to plasterers, painters and brick layers.

Mr Schwarten said that in another sign the project was nearing completion, all cranes on the site had now been removed to pave the way for excavation in preparation for the laying of the turf.

"At one stage, there were 17 cranes operating on the site, almost completely covering the pitch area," he said.

Mr Freer said Castlemaine Perkins wanted to mark the milestone with a typical gesture of Queensland hospitality - shouting the workers a few cold XXXX beers.

"Given the brewery's proximity to the new stadium, we thought it was the neighbourly thing to do," Mr Freer said.

In other areas of the redevelopment, two of the catering facilities at the stadium were completed last week, providing the catering contractor with on-site training for its staff over the next month.

During the next couple of weeks, Joint Venture staff will move out of their Western Stand offices to facilities across the street as full-scale work commences on the refurbishment of the Western Stand.

The installation of the stadium seats is also well underway.

Mr Schwarten said the landscaping around the stadium would commence later this month.
