I am including the apparatus in this as what makes this whole thing work as fa as I am aware.

...it should also be noted that I suspect that the thing is designed like that as it deals with more extreme conditions from earthquakes and typhoons in that region. While that would be much less of a problem here at One Bloor W..

Seismic attenuation in buildings starts below ground level though, so while a TMD would play some role in an earthquake, more is going on down below to keep everything up in the air during an earthquake, including that TMD!

When the media was up there several months ago for the 300m celebration, there was no noticeable sway. There was also no wind. When we went up Pinnacle's SkyTower more recently for the 100 storeys celebration, there was no noticeable sway. There was some wind.

If you've ever had a chance to go to the bathroom in the CN Tower's SkyPod (unlikely as it's closed to regular visitors) you'll be met by a violently swishing toilet on windy days. If I recall, the CN Tower bends a mind-blowing 1 metre in either direction at the top. Don't ask me how I got the chance to see that. 😬🚽

Taken today from Galleria On The Park during sunset, the moody sky, the sun kiss, just all lined up.

Photos taken today, Friday (Dec. 19). A chilly and very windy day... At the top, the mass dampener is somewhat visible from one of my shots from the west, the last one here. (That's what the dark shape is, isn't it?) Further down, the Rail Climbing Systems (RCSs) installing the building's skin have moved up since I posted a week ago on the east and north sides, now resting near the top of the last mechanical level, floor 78. The west one remains at 76, the south at 73.

Is this Toronto's first Mass Tuned Damper, or are there other such installations? 🤔

Someone correct me if I’m wrong but, aside from the CN tower, I’m pretty sure M3 at M city beat this as the first skyscraper with a Tuned Mass Damper in the GTA

So there’s only one completed TMD right now, and this one will be the next. And also I’m also pretty sure pinnacle one Yonge will be the third skyscraper to have one installed.

Actually I'm pretty sure M1 and M2 both have TMD'S
