It's about time one of us found this! How'd you manage to track it down?

That reminds me, steel for the eastern portion of the hotel is now visible from High St (photo is from Saturday)

Question on this: Is poured concrete to be expected all the way to the top? or will this serve as somewhat of a podium before transitioning to steel for the upper floors?

 

 

I imagine once they get to the tower portion it will be all steel. That concrete work is really complicated! Looks like the three concrete beams they're pouring now create a wide open space below. I recall there's a ballroom in there somewhere. And those large beams need to carry the load of the tower above.

FWIW the Joseph was concrete all the way up. But 225 on the Commons was half and half. Certainly not an entirely equivalent buildings but I wonder if the use can also dictate how it is constructed. Is a hotel more likely to be concrete platforms all the way up? 

 

EDIT: I will also add that the Joseph added 1 concrete floor about every 1-1.5 Weeks. So even if the Hilton goes concrete all the way up, the tower will rise relatively quickly if it keeps a similar pace based on the tower footprint not being terribly different than the Joseph.

The rear half of the building is going up in steel, but I imagine the rest of the hotel tower will be concrete.

^You might be right. That makes sense. I was hoping for steel since that would go up faster.

You can see the tower beginning to rise in this view from the Crew's OHPC construction cam which finally updated its HD panorama shot for the first time in nearly two months.

It's really interesting watching the construction cam to see how this is coming together. Last week was spent setting scaffolding and placing cables for the post tension slab. Today they are pouring level 6 (I believe).

Here's the progress as seen from the OHPC construction cam over the course of ~2.5 weeks. Things have been pretty slow moving. If they are doing poured concrete the entire way up, vertical progress is going to continue to be pretty slow, I would imagine. 

 

To add on to my post above, build out of the tower is planned to completed 13 months from now, according this instagram post by the general manager of the hotel. He also said they are starting work on the 7th floor right now, which is the first floor of guest rooms.

I’ll bet it will go faster once they start the guest room tower portion. From that point up each pour will be the same. Everything below the tower looked really complex on the construction cam - large openings in the floor, leaning columns, larger floor plates...

 

I read that in Toronto, condo towers add a floor every four days once they get above the podium.

I think you are right. The pace will definitely need to pick up if they are going to wrap things up 13 months from now.

I wonder at what point it is safe for workers to start doing interior work. Can't imagine they wait until they top out to start doing things on the inside.

I've only seen a few true towers built but that seems to be the SOP, they'll start closing it in at the bottom as the top progresses.

I just drove by and noticed mechanical rough-ins are underway. Interior finishes won't start until the building enclosed. Like wpcc88 said, we'll see exterior finishes begin while they are still forming upper floors. The interior trades will follow that.

I feel like construction on this is taking forever.  Weeks of updates and it doesn't really feel like much has changed in my opinion. Am i the only one who feels this way?  Why aren't we seeing steel going up every day by now?

We are. 

From the Feb 24th posting at the top of the page, up to today, there really hasn't been any drastic changes.  It's moving very slow!

They've added 3 very complex floors to the tower section in that time and done a lot of steel framing on the ballroom portion. They're starting on the guest room floors now which will likely rise more quickly.

Additionally, please refer to Pablo's post on April 7th, his explanation of the complexity of the lower 6-7 floors applies...

There's a lot going on. I may have some of the construction terms wrong but you get the idea. A buckhoist is a construction elevator. I'll bet they'll pour the 7th floor tomorrow.

 

Is this going to be concrete all the way up?  I get that pouring concrete is timely, but the post showing the comparison proves my point.  From FEB 24th to Apr 12th, they added 1 floor.  In the Feb 24th pic, you can see the really thick piece of concrete being framed.  In the Apr 12th pic, you can see that their is only 1 floor (possibly 2, i cant tell if that's 1 or 2?) above it.  It is what it is, i was just simply stating it seems like its moving slow.  By comparison, they two structures on the Scioto Peninsula are in warp speed.  Maybe its just me lol....

Define "moving slow."  If all you care about is vertical progression, then sure, it will currently seem like it is "moving slow."  At the start, they spent months doing foundation work underground before anything was visible above ground.  It felt like it was "moving slow" but there was a ton of work happening to prepare the building to rise.  The same is true now.  A ton of work is happening, but vertical progression is currently "moving slow" because there is so much work to do at these levels.  As others have mentioned, once you get to the cookie cutter, repetitive upper floors, vertical progression will happen more quickly because there is less to do at each level.

The building that has topped out on the Peninsula is a steel frame box where every floor is the same from ground to top.  See my above comment to understand why this would rise more quickly than a building that has complex engineering needs at different levels.

It's 3 floors between those dates. I've been watching on the construction cam and those giant 3 concrete beams needed time to cure before they were loaded with additional concrete. 

If you get the chance to go down there in person and up close, you can see the complexity of these first 6-7 floors.  The contouring and literally angular concrete pours of zig zagged columns, is very unique and odd up close, but they've had to pour these custom angles to work around the nearby walls of the convention center.  This takes a lot of time and customization. If I get a chance in the next few days I'll try to go down there and get some close ups to provide context to this.  The peninsula are box/square buildings, hard to compare.  I suspect the upper floors/tower portion will rise faster in theory, however, this project is a government project, not "Hilton".  No offence to government and our local politics, but the contracts secured for much of this labor I'm sure is more drawn out on purpose.  I can bet you that if Hilton as a corporation/owner was in control and building this, the timeline would be even faster.

In addition to the complexity of pours, its how much time it takes each pour to cure to "safe to continue" state. Similar to what we saw with NVMM, the structure isn't large by any means, but it has some really complex pours and extremely dense/thick pours that take a long time to cure. You have to very carefully control the rate at which concrete cures to avoid cracking and chipping. General rule is the larger the pour, the slower the cure. Thats what we are seeing here, complex and dense pours that are taking a bit longer than an upper floor would since higher floors are pretty formulaic/repetitive. 

 

If the upper floors are steel (unlikely from what I am seeing), this will rise very very quickly and if they are poured, this will likely rise a floor a week.

^The amazing thing is that they are driving scissor lifts on the slab the next morning after the floor slab pour and setting up forms for the next set of columns. What seems to take time is setting up scaffolding to hold the next floor and positioning all the cables.

Something that I definitely didn't notice at first in the renderings is that the top-floor ballroom cantilevers over the drive below -- this is such an interesting building. Glad we're getting some nice complex exterior forms to match our equally complex convention center

Man, I can't wait to see this exterior finishing start.

Insane build. These concrete teams must be top notch.

It really is when you step back and look at it.  Going to be a GREAT addition to the skyline.

I saw this awesome aerial from columbusdronie on instagram. It gives a good sense of how much the tower has grown so far.

 

Looks like the elevator core is now taller than Hilton 1.  If not, it's very close.

 

^ Based on that pic, it looks like we'll be seeing a crane jump within the next month or so.

Someone above said it seems like the construction has been slow on this and after seeing it again today I have to agree. I’m sure it will pickup speed this summer though.

This was a quick pic I took in my car about a week ago....

I mean, all things considered, work on this giant hotel built to expand the capacity/draw in larger convention crowds... Not like they need to be in a huge rush at the moment...

I've actually been of the opposite opinion - I feel that this has progressed much quicker than I anticipated for a concrete poured structure. 

Looks like steel is expanding towards the back -- hard to tell from this angle, but is it cantilevered, too? Or partly? I don't remember if the entry back at that point gets a multi-story volume, too. Or if they're just trying to keep that space open to the ground?

^That will all get filled in. At some point the small crane that's been used for steel erection will need to be removed. From High St you can see the cantilever circled below in red.

 

Here's the view from the OHPC HD construction cam, which finally updated for the first time in a month yesterday.

I think a section was added this week. The boom of the concrete pump on top of the elevator core in the above photo was getting close to the tower crane jib. Looking at the construction cam today the jib is well above the pump boom.

Ehh, I'm not so sure. If you click back through the construction cam day by day, it doesn't appear the height of the crane has increased at all. Maybe it's just the perspective of the two pictures above. 

^I think you're right. I went to the site during lunch and counted segments.

Although the crane doesn't seem to have jumped yet, the elevator core is moving up to the next floor today.
