Post from the EPA on LinkedIn suggests that remediation of the site will be complete by November 2021, with construction of the building to follow.

Remediation of what though? I'm interested to know

Whatever it is, it's black - looks like oil. Given it's been there for 50+ years, I wouldn't be surprised if it's mixed through with PCB's or similar.

Wow, never seen anything like that at a construction site before.

NRAH had heaps of remediation like this. It's a very contaminated area. Much rather they take their time and do it properly!

Wow, never seen anything like that at a construction site before.

I did several years as a Geo-Environmental engineer working on brownfield sites in and around central London - including the old gasworks on the Isle of Dogs.

Then there was the joy of working around the naval dockyards in Portsmouth with the very real risk of standing next to an excavator as it hits one of many unexploded WWII bombs.

That stuff looks pretty pleasant in comparison...

That's the legacy of the old Adelaide rail yard!

Their post mentions “due to the odorous nature of the site contamination in soils requiring remediation to occur within a tent structure which is under negative pressure, with all exhausted air being treated via activated carbon to remove any odour.”

Did the rail yards exist before the city had a common sewerage system? Did the country trains of the day have effluent tanks?

If anyone is interested there is an older planning presentation available online
https://www.saplanningcommission.sa.gov ... hments.pdf
Pg 71 has some good architectural drawings. L00 looks to be access off George street in the NW corner and L3 is the entry off North tce.

I heard the old rail yards had a bore or similar well the was used as a coinvent disposal hole for Oil, diesel, etc

There is a massive underground drain from West Tce under the new RAH to the river Torrens. This drains the whole of the north west area of the CBD bounded by West Tce, North Tce, King William St and Grote St. I believe this was relocated or buried deeper when the new RAH was built.
One of the problem pollutants from the railway maintenance period is "duff", which is very fine coal dust particles.

Update 28/3/2021 still digging & still treating polluted areas.

Nice pics mate! Are you working there?
It looks like they are removing the tent today.

[Listy]

Yes, the tent has come down (for the final time?), revealing a deeper bit of excavation which might be for the bunker. The area at the front of the photo has all been carefully leveled and rolled flat.

[CBD05]

Wow, they worked all weekend and filled that hole in. I walk past every day, it seems they dig holes and fill em up just for fun hahahaha

[EBG]

There was a new piling rig on site this afternoon. perhaps they are finally ready to start actual construction?
no time for a picture today _ maybe soon.

[EBG]

The piling rig now on site .
