It definitely has nothing to do with any suspended loads bonking the structure.

Looking for crack in Steel or HollowCore??

So the Building is moving?
They want to know how much?

plrh · #**5664** Posted **Dec 7, 2020, 4:39 AM**

I wonder if it's the hollowcore or the cast-in-place concrete that's problematic. There shouldn't be much force on the hollowcore, but they are prestressed, so maybe they are being delivered too soon?

I have had precast products delivered still warm to the touch and installed them. Not building parts though.

Does anyone know who's redi-mix it is for the core?

I was hoping it would just be masking tape and sharpie marks

Thanks for the link to those monitor devices. After reading on them very briefly it sounds like they are mainly used on cracks. That would be extremely alarming if they are monitoring cracks already. Or is it that they can be used on steel jointery to check for movement? Sorry, I didn't read up on everything the device does.

esquire · #**5667** Posted **Dec 7, 2020, 4:21 PM**

On one hand it's alarming to read about this, but on the other hand I wonder how many times situations similar to this happened in the past before internet forums, yet the buildings are still standing and we're all none the wiser?

Haha. We do have a certain collective PTSD.

"I heard a rumour that Artis was going to take down the top 20 floors and send the steel to Calgary for a project there!"

The foundation of this building is socketed into the bedrock. Probably not an issue.

The core is reinforced concrete. Probably not an issue.

The floors are pre-cast hollowcore. Probably not an issue.

The steel frame has about a million different connections and is bolted and or welded together. I suspect the issue is within the connections. And that's really hard to pinpoint, unless something obvious is wrong. Hence all those crack gauge things, etc.

Biff · #**5671** Posted **Dec 7, 2020, 4:58 PM**

So look Drew, what we really want to know is - is the building going to fall over, and if so when? I would like to video it and post it on social media.

I believe from what I've heard-- your right.

I have an analogy experience that happened to me recently.

In 2015 I bought this used tall computer desk from a second hand store. It worked really well for the laptops that I used on it.

Unfortunately, in the past year alone I burned thru 3 laptops due to carelessness of spilling water or coffee near them.

So this summer I decided to switch back to buying a desktop PC.

I had no LCD monitor, but a friend of mine said he had one he could give me.

The monitor is 20" and just fit on the desk.

One day as I was pressing the Shift key on the keyboard the screen did not light up. So I pressed the keys again.

Seconds later the whole desk came topping over to the right, towards my livingroom window.

Point is that in a similar way,, all the hollowcore and steel and glass that's being placed atop 40 year old piles that were meant for no more than a 20 storey building (based on 1974 drawings). It can only lead to a catastrophic failure at some point if something is not done soon.

LilZebra · #**5677** Posted **Dec 7, 2020, 10:28 PM**

Does anyone know when the next Artis AGM is scheduled?

Would the new Board reveal the structural building problems they're having at such a meeting?

Presumably you didn't hire a structural engineering firm to review your desk's capacity for the new load, right?

I'm not saying there isn't a problem because it sounds like there is one. But the idea that they just plopped double the load thoughtlessly onto an aging structure and that somehow this makes catastrophic failure inevitable seems... a bit much

Especially when you consider they actually went and did extra reinforcements to what was already there, for like a year or more before building.
