I don't know if we ever got the specs on that BMU, but that thing must be ginormous. What's the stickout on it? 60-70'? I've never been that far out on a house rig, but the odd times I've been scoped all the way out horizontally on a boom lift it's a bit unsettling to watch the whole thing bending and straining under the load. I bet it's zero fun to have that experience 650'+ off the ground.

I think they changed BMU providers during construction but I’m not sure if this 2012 posted version or the manufacturer is of the supplied BMU but I assume the dimensions should be applicable.


Building Maintenance Unit

Remember the question about how the L-Tower windows will be cleaned, especially the ones on the curved north face? I have been exchanging emails with Paul Belaskie at Ankor Engineering Systems Inc. They engineer, manufacture and install building facade access and safety systems across Canada, specializing in engineering systems that are required to provide workers with safe access to work areas where fall hazards and building maintenance are needed. Ankor Engineering is the sub-contractor at the L Tower. This is how Paul described to me the window cleaning solution for the L Tower:

"Simply put there will be a crane type Building Maintenance Unit (BMU) on the opposite side of the long curve. It will suspend a swing stage over the long curve. The swing stage will engage a special mullion strip (guide rails) that will draw the stage close to the building the entire length. The BMU will be similar to the one we used on Trump Toronto."

Paul now shared a drawing of the impressive L Tower BMU that they are going to install. He said it would be all right for me to post the drawing on UrbanToronto. Click on the image to enlarge it to full size.

Oh my god. Wow. At 31649 mm (and that's not even to the fulcrum) that's over 100'. I get that having the extending counterweight helps mitigate that, but holy crap. That thing is a monster. I'd love to see the load charts for that.

So, I bet, would those who might have been "out" on it!

Source for this is a friend who sent it from a local Facebook group. i.e. no idea whose photo it is so if that is a problem, let me know and I can delete.

I was expecting the crane to be left sticking out of the lobby/theartre portions below like a well lobbed kitchen knife. Instead, it appears a couple of shattered windows on top portion of tower with BMU in question still mainly intact. Good news, likely less expensive and difficult to fix and far less damage to peeps and property.

Thanks for the pictorial update @jameskoole. /bows

But a further blow to the reputation of the building!

Hey while on the topic of this tower that has never experienced a single problem in its life, heres some photos I took of the absolutely most perfect building in the city a couple months ago.

I'm sure it will. And in the spirit of why we can never has nice things, this is why Toronto gets stuck with conventional boxes. /sigh

Slightly unrelated but thanks to the mod who complied all my photos into a single post! :)


On the note of the building. Do we have any idea how extensive the setup will be for repairs?

Rest assured that if any of us know it will be posted here. I doubt the Condo Corporation (the owners) and the 'crane contractors' have worked out yet what to do and how to do it. Lots of insurance issues will need to be resolved too.
