A joint report by two construction industry groups has found the sector will lose 8,000 jobs in Queensland by 2016.

The 2014 Major Resources Project report by Queensland Major Contracts Association (QMCA) and Construction Skills Queensland predicts the state will experience weak growth over the next few years.

They are anticipating the amount of major project work in Queensland will halve by 2016.

Tony Hackett from QMCA says the boom is definitely over.

"We were predicting I think 40 per cent reduction, it's now gone out to close to 50 [per cent] and job losses have increased," he said.

"It's largely because we haven't had the replacement projects coming through.

"In fact, many have been either cancelled or indefinitely postponed."

Mr Hackett says a percentage of the job losses were expected, with three liquefied natural gas projects on Curtis Island off Gladstone winding down.

But he says the cut in employment will be more serious than originally predicted.

"We see a role for government ... to invest to the extent they can, to smooth the curves you know, the peaks and troughs," he said.

The report predicts future developments in Queensland over the next five years will be focused in the Galilee Basin and the south-east corner.
