Yes, the focus is on completing the hotel portion first as that is the norm for these mixed-use projects however, that is not why there has been slow progress on this project. As I mentioned before, the constraints on executing this project is one of the most challenging I have experienced due to City of Ottawa lane use time restrictions, daily local resident complaints that are just outrageous, the choice of using precast panels on a site that has zero real estate to use as a staging and installation area and many more reasons that I won't get into at this time.

While I am a fan of the different exterior design with the use of the precast panels for Tower C, the constraints of this location was an oversight during pre-construction planning. As I also mentioned before, the precast cost and quality is substantially higher than the cladding that is on Tower A & B but the installation is much more difficult.

The other main factor in the slow progress was the choice of tower crane and the placement of the tower crane. The forming contractor decided the change the original plans of using the conventional hammer head crane placed within the building footprint to the current luffer crane located outside of the building footprint. Long story short, that luffer will be replaced by the end of May back to a hammer head but at the current location. It will provide a more efficient work methodology.

As for current progress, floor slabs are now being poured on a 7 day cycle and have been for the past four levels.

That's it for now!

Thanks for the excellent insights! It’s amazing how much weight this city gives to complaints.

Thanks BlueJay. Appreciate the insight.

I don't live in the area, but I walk/drive by a couple times a week during rush hour, and it's really not that bad; not the noise, not the traffic, not the pedestrian detour. Constructions is just part of living in a Downtown area.

It is 6 floors higher and I added 7 just due to it being 1 block closer from this angle. It's not the great clump buster we want....but it's the clump buster we deserve.

East facing views are on track for best angle i city imo. Good work.

Progress Update

[ponyboycurtis]

At certain angles its such an illusion that there isn't a tiny floor for short people there.

[J.OT13]

We're 11 floors up. Some decent progress. Can't wait to see it's impact when it's topped out.

[OTSkyline]

Am I missing something or is the cladding changing colors on the highest level they just installed (from light grey to charcoal/dark grey)?

It does change from white (what you might be calling light grey) to dark grey.

From BlueJay on Skyrise. First elevation is facing Slater, second is facing Bay. The dark cladding seems to just be a corner of the lower portion on the east side.

Should also get a different black material on the Bay (West) side. Again from BlueJay.

That does seem to jibe with this rendering:

I like the curves on this one, it breaks up the boxiness of that part of the skyline...

[rocketphish]

Today's progress. And I see damage to multiple precast sections along the "corner" joints. I suppose that's all fixable?

This building is huge. Should make a massive impact, not only with its height, but its shear size, not unlike the behemoth that is PdV C.

The city really should’ve got those power lines buried when Bay/Bronson/Queen were being reconstructed.

On the plus side those power lines are hiding a chunk taken out of the precast in the photos.

I saw 2 sections of precast on the highway the other day on a low boy flat bed. They are freakin huge! That entire flatbed was only carting 2 sections. I guess if it wasn't a low boy it could take more. The quality seemed nice as I tried not to stare at it too much.

These latest photos look great. If you are doing precast this is the uniformity that it should be. Not seeing anything in the way of color variation between sections. That missing chip on the rounded corner will be a — to patch up though. The section below it also has a tiny little piece knocked off. I dont imagine these are very forgiving when being lifted into place and bump into something.

I'll have to go in person and see. This last month has just been such lousy weather for an extended walk.

I walked by tonight and they had two of them sitting on a flatbed on the street, so I got a chance to check them out up close. These things really are enormous — as you can see in the photos, one is 7,292lbs and the other is 10,203lbs! The windows are built in.

[ponyboycurtis]

Interesting there are XYZ co-ordinates.

Not surprised at the weight given the size of them. I was mildly shocked driving next to them. Never expected them to be that big. Keep in mind I haven't been by the site since it was approaching grade.

[BlueJay]

Just adding to the conversation here. While those precast panels are massive indeed, there are panels on that building that weight up to 16,000 lbs as well. As for the damages to the panels that are installed, yes they are difficult to repair but it is done with the same colour mix that they use at their manufacturing plant and do blend in over time.

As for the power lines, I had lobbied the City to bury those lines while they were digging up Bay Street for the watermain and sewer upgrades that were taking place 1.5 years ago but was told it wasn't in the budget and that it will be a separate project in the future. I even offered to contribute financially. Budgets are budgets I was told. The cost to do bury the lines while having open excavations already would have been a fraction of the cost that it will be on a power line project alone. Try to make sense of that.

On another note, level 14 slab will be poured this coming week as the 7 day pour sequence has been progressing well. There will be a delay of that sequence once the level 17 forming starts as that is the pool and spa floor which is also a double height level. The remaining 19 levels will resume to a 7 day pour sequence after that.

Happy Easter!

Thanks for the background. It's insane how the City refuses an offer to help bury hydro lines. Hydro Ottawa is also very much on board to help finance such projects. It's only going to get more expensive and disruptive to bury them later (if ever). Between climate change, the battle for space, and urbanism, not to mention golden opportunities that come once every 50 years when streets are opened up, it should be City policy to bury hydro lines at every opportunity in urban areas.

Can't wait to see level 17 complete. That will be a huge milestone for this project.

[J.OT13]

From yesterday morning.

View of the Renaissance construction site at 11:29. I think we can see the pool and hot tub being formed.
