Toronto Sugar Wharf Condominiums (Phase 1) | 231m | 70s | Menkes | a—A

[mburrrrr]

My lake / (transportation) view someday. Sooner the I may have planned. Not to any accuracy or scale. Anything over ~20 flights doesn’t really matter. No complaints.

Maybe add a rail deck park and remove the highway then it would look like Central Park? Okay, back to work, dreaming is over.

Pictures from this week
Final ramp excavation.
A minimum of three chutes to direct pour as seen from.this angle.

Wednesday morning

Saturday
That will be one huge slab.

There must be something exciting to see down there.

2 excavators removed.

That slab looks large enough to support the CN Tower.

Thats one thick base slab to anchor the towers down. Doing 4 section pour at various times.

 

[ChesterCopperpot]

It's almost 10 feet thick

Hindsight is 20/20, but i wish i had bought shares in any of the major concrete firms in Toronto 10 years ago. I'd be a richer old fart by now.

 

[old boy]

Fantastic pictures everyone ! The mass quantity of rebar takes me back to the days of constructing base slabs at Darlington NGS in the early 80's.

 

[Contra]

That's a honking big raft they have going there.

 

[mburrrrr]

Looks like they are almost ready to pour. Maybe Saturday?
They added two more chutes from my viewpoint, 5 + maybe 5? more mirror image out of my site line and two cranes?
Quick guess at 12,000 m3 of concrete.
How many trucks will be lined up?

A standard cement truck holds approximately eight cubic yards of concrete, while the larger, articulated trucks (of which there are some, but not that many in Toronto) holds approximately twelve cubic yards of concrete. At a ratio of just over 1.3 cubic yards per cubic meter, 12,000 cubic meters would come to around 15,600 cubic yards. Depending on the mix of standard and extended (articulated) cement trucks, that would work out to a maximum of just under 2,000 truck loads , with fewer loads required if there is a meaningful number of the larger, articulated cement trucks involved in the pour.

I cannot recall the number of truck loads required for the pours at the Minto Quantum project in the Yonge and Eglinton area, the largest single pour in Toronto that I am aware of. When this pour took place in 2007, it required approximately 2,700 cubic meters of Agilia concrete - a record setting amount for a continuous pour of Agilia concrete at that time. The Minto pour was truly a sight to see - three batching plants involved, in different areas of the city, so there was a smooth flow of trucks from three different directions to the Yonge and Eglinton site. There was a large scale private duty police presence around the site, with at least six concrete pumps on working - four on Yonge Street, and at least two in the pit (possibly more) that I can recall.

So if the estimate of 12,000 cubic meters is only half-way accurate (I kind of suspect that the actual pour may be somewhat closer to 5,000 - 7000 cubic meters), it will still be a sight to see when it takes place.

^^^^ Will definitely be a sight to see

There was a raft slab pour in Houston a few weekends ago for Hines Texas Tower that was 12' thick in the interior portion - 8' deep around the perimeter .

Over 1,700 trucks pouring 13,799 cubic yards (10,500m3) over 20 hours. That's one truck every 45 seconds.

 

[mburrrrr]

They are pouring today with 9 feeds.
It looks like the NW corner is isolated for a separate pour.
4-5 minutes to unload. ~1minute to exchange trucks. ~100 trucks\hr
Poor guys, 3C and raining today while it was sunny all week.

 

[cc46]

Large pour today. And Harbour St is closed to accommodate the concrete truck traffic.

 

[mburrrrr]

10:30 am leaking joint spraying concrete on the south wall.

7:05 WB accident watching construction or their phone and not the traffic.

Where did everyone go, we’re not done yet.

7:15 EB accident - rubber necker or watching construction.

Almost finished by Earth Hour

I find it interesting that just 250 m to the west, the Phase 1 One Pinnacle Condo seems like it is sitting a “normal” foundation on level P6 for the 27m x 29m 65 floor building while the Sugar Wharf Phase 1 70 story 32m x 30m condo is sitting on P4 with ~3m thick base. I wonder if the design difference was triggered by the 5 extra floors or the existing ground conditions or engineering safety/preference?
