Asbestos is not dangerous until it is disturbed, cracked or broken up. Once they found it they have stopped works. Removal of friable asbestos is undertaken under neg air conditions (if they are not sure they will treat it as friable). Back in the day they would of just buried it without the same kind of care that they now treat this kind of material.
I'm not sure if regulations and whatnot have changed, but I know of at least one local demolition company and a large commercial land holder here, who will basically just dispose of it wrapped in black plastic tarp type material. They'll have a guy come in and setup some air monitoring bollards around the perimeter of an exclusion zone that give an audible warning if asbestos is detected in the air. They suit up with masks and everything of course.mattblack wrote: ↑Wed Oct 25, 2023 10:26 amAsbestos is not dangerous until it is disturbed, cracked or broken up.

It depends on the nature of the material - what exactly it is, how easily it can be removed etc. If it's a relatively straightforward job such as removing asbestos-cement sheeting/fibro piping etc then careful dismantling with appropriate dust-mitigation measures (such as minimising damage during removal, using water misting), wrapping and sealing in two layers of 200 micron plastic and then disposing at a licenced facility via a skip or truck is pretty much the right course of action - so what you've described sounds OK.rev wrote: ↑Wed Oct 25, 2023 3:26 pmI'm not sure if regulations and whatnot have changed, but I know of at least one local demolition company and a large commercial land holder here, who will basically just dispose of it wrapped in black plastic tarp type material.

Not sure if that was the proper way to remove and dispose of it, because that same demolition company I know did some questionable things when bringing down buildings greater then 3 levels in height

Market Square development hit by another delay due to asbestos find
A $400m CBD redevelopment has hit another stumbling block, with major construction halted until the new year after an asbestos find.

The $400m redevelopment of the Central Market Arcade has hit another stumbling block, with major construction halted until the new year following the discovery of asbestos during demolition work.
Contractors have spent several weeks remediating the soil, and while that work is expected to wrap up this week, developers say construction is unlikely to resume before the end of the year.
Work on the Market Square project – a joint venture between Melbourne developer ICD Property and the Adelaide City Council – was originally meant to start in 2021 and be completed next year.
But the project has been hit with a series of delays, most recently due to design changes which were approved earlier this year, paving the way for demolition work to commence in June.
When national building firm Multiplex commenced demolition and construction work, the company’s state manager Andrew Warren said construction was likely to take around three years to complete.
According to latest estimates, the first stage of the project, including the office component and first-stage apartments are due for completion in 2025, ahead of a new retail offering and hotel in 2026.
ICD Property chief executive Matt Khoo said the latest setback was unlikely to result in any “material delays”.
“Asbestos removal and associated site works are expected to conclude this week,” he said.
“Formal certification to confirm completion of works is necessary prior to construction progressing.
“There are no material delays to progress as a result of this work.
“We’re still awaiting formal certification for completion of the asbestos removal works and at this stage we’re expecting to resume normal works in the new year.”
The Market Square development will feature a hotel, 234 apartments, 21,700sq m of A-grade office space, a 11,000sq m-plus retail precinct and a 3000sq m elevated garden.
In March, the council approved an additional 21 apartments, more office space and two extra storeys, as well as several other design changes.
The amendments came after global construction costs rose by around 20 per cent, prompting council to increase its contribution to the project to $31.92m, $9.3m more than originally planned.
At the time Mr Khoo said it was “no secret” the construction industry was under pressure, but the company had been able to “safeguard Market Square from the worst of it”.
