The deaths of two workers on construction sites in the same Canberra suburb have been deemed "completely unacceptable", more than seven years after a damning report into the industry.

His death came less than a month after a 47-year-old man died on a worksite in the same suburb WorkSafe ACT vows to crack down on Canberra's "concerning" safety culture

A 60-year-old worker died after falling from the second level of a house under construction on Temple Terrace in the growing Canberra suburb of Denman Prospect yesterday.

A 47-year-old man died after a pallet of tiles fell on him while he was unloading a truck at a construction site in the same suburb less than four weeks earlier.

Last month a crackdown by WorkSafe also resulted in more than 70 non-compliance notices being issued over 28 residential construction sites across the ACT.

ACT Work Safety Commissioner Greg Jones said the safety message was clearly not getting through to residential builders and contractors.

"Enough is enough," he said.

"Safety needs to be our number one culture and clearly it's not in residential.

"Two workers tragically passing away within three weeks is just completely unacceptable and that safety culture needs to be improved."

Mr Jones warned that WorkSafe would be continuing its "intensive compliance blitz" on building sites.

"We will not tolerate non-compliant workplace and safety," he said.

"We will issue fines, infringement notices or shut down sites if there's non-compliance."

'Culture of lawlessness' continues despite 2012 inquiry

In 2012, an inquiry into work health and safety law compliance within the ACT's construction industry was carried out in the wake of three worksite deaths.

The inquiry found the territory's serious injury rate for the construction industry was 31 per cent higher than the national average and that safety was "not given the priority it should be given".

It resulted in the Getting Home Safely report that made 28 recommendations to improve safety in the construction sector.

But more than seven years on, Zachary Smith from the CFMEU said little had improved.

"There's a culture of lawlessness in the ACT construction industry, in particular the residential building industry," he said.

"There are certain builders that are prepared to put profits ahead of safety of workers and are prepared to risk workers' lives in the pursuit of construction."

Mr Smith said WorkSafe needed to be better funded so more inspectors could attend building sites.

"We need to see an increased focus on enforcement and prosecution, especially of repeat offenders by the regulator," he said.

ACT Workplace Safety Minister Suzanne Orr admitted the government was particularly concerned by the deaths, given the crackdown carried out by WorkSafe only last month.

"We do need to take our safety seriously. Safety is everybody's responsibility," she said.
