QLD's mining-driven building boom 'to end soon': report

The state's civil construction activity is expected to reach its peak as early as 2014, according to economic forecaster BIS Shrapnel.

Report author Adrian Hart says the recent spike in civil construction work is driven by liquefied natural gas (LNG) and coal projects.

"When you look at the timeframe of these projects, many of the largest ones, particularly the LNG projects, are timed to be completed towards the middle of the decade," he told reporters.

"What it's creating is a large bulge in construction activity right now that will be sustained through the next three years.

"But after that, as these projects wind down, they'll likely leave a sizeable gap in work.

"That's when we will probably see declining construction activity in Queensland - around the middle of the decade."

Hart said that unless a new round of mining projects begins in Queensland, construction workers will move to other states experiencing growth, such as Western Australia.

That doesn't necessarily mean the industry will suffer.

"What we will see in Queensland ... is a shift back towards urban construction projects that are probably not going to be fully addressed over the next few years while the mining boom is going gangbusters," he said.

"There's other projects that need to be done in and around Brisbane, (such as) rail, road and water projects.

"We'll probably see a return to some of those projects."
