A construction sand pile is the place where workers are digging a road in order to build the roads needed for the next few months.
But this year’s sand piles were built on the wrong site.
In some areas, the sand was built on top of road construction.
The sand piles also lacked the necessary drainage, which makes the work easier.
In Melbourne, construction sand is a popular construction material because it is cheap, easy to work with and easy to manage.
It also makes it easy to dispose of, unlike other construction materials.
But not in Queensland.
Construction sand is made by placing a stack of gravel in a bucket and adding sand to the top.
This process is repeated until a pile of sand is large enough to fill a bucket.
But the sand piles in Queensland have a different set of rules than those in NSW and Victoria.
In NSW, workers have to have a licence to dig, and workers are responsible for the cleanliness of the construction site.
Workers are also required to dispose their sand piles, so the state does not require that contractors provide them with a disposal plan.
However, in Queensland, workers are required to make sure they have proper disposal equipment and do not have their sand pile placed on the roadside without a road-cleaning permit.
This makes the job of sand-digging much more dangerous.
In 2016, one worker died in a construction sand-hole, while another was injured in a separate construction accident.
In the first three months of 2017, four workers were injured in construction sand.
Thats not to mention that at least two other workers have died and at least 20 others have been injured in accidents involving construction sand in the past five years.
In 2015, a construction worker was killed and another was seriously injured when a large construction sand hole collapsed on them.
In February this year, two construction workers were killed in a sand pile collapse on a highway in New South Wales.
In May, construction workers on a major road project in Sydney were injured when construction sand collapsed on a road near the city centre.
The construction work was delayed for more than a week, causing the roads to be impassable.
There is no evidence that sand piles are unsafe.
In Queensland, the state government is responsible for ensuring that the construction work is safe.
However there is a requirement to keep the sand and other materials on site for safety purposes.
This requires a road cleaning permit.
Queensland has strict rules for sand-clearing and it is illegal for a contractor to remove the sand without a proper disposal permit.
The Department of Environment and Heritage Protection has told ABC News that it is not aware of any construction work in Queensland that has been affected by the sand pile accident.
The state government has issued fines of up to $10,000 for people who break the rules.
