^ yep

Klingaling,

Do you know when the "big" concrete pour will be for the foundation?  It would have to be sometime before steel starts to rise in September.

I'm not sure there will be a large concrete Matt incorporated into the foundation.  I was under the impression that this was all caissons and grade beams.  Pretty sure that is the case also considering elevator cores are out of the ground already.  Not going to pour the foundation around them.

 

Seems like there has to be some kind of concrete foundation poured.  But, it has been so long since we have had a building with caissons that I forget the construction techniques.  I think the last building with caissons was the Key bank and that was over 20 years ago.

I notice they have light plants out in the photos above.  Must have a big night pour coming up.

Actually I believe the Convention Center had drilled caissons as well.

Looked for the crane coming across the Innerbelt (heading northward) and it's not quite tall enough to be seen. Oh well, eventually ...

So I happened to check the webcam last night and this is what I saw... It's like the Ark of the Covenant was opened and the demons of Hell were released, signaling a new positive age in Cleveland.

 

Don't look at it! ...or your face will melt off.....!

Development is a dirty business. It's all fun and games until you've accidentally brought upon the apocalypse.

Reminds me of a movie I saw as a kid.... Five Million Years to Earth

I wish we the The Med-Mart and The Hilton could switch location for skyline reason. The Hilton, it seems, will be obscure from many vantage points.

In the Buffyverse, there is a hell mouth in Cleveland

 

We should keep an eye on this construction to make sure no other demons escape.

I'm not sure anyone on this board would pay much attention otherwise.

^I'm fine with it if they boost our Downtown population numbers.

X has the right attitude.  We must embrace diversity.

I like this view of the crane...

 

There are some new renderings of the hotel on the Cooper Carry website.  These are the most detailed renderings I have seen so far.

Looks nice. I like the vertical white beam of light up the building

I'm looking forward to taking this picture again after the project is complete.

 

Hopefully we'll have those rainbow laser beams coming from The Q then too!

Though they appear to be coming from the Q in this picture, the laser beams were coming from the science center.

Really? Cool!

Changed the title of the thread since we all know what it is now.

It's great that the base and the tower each have their own unique visual identity.

As of 8/15/14:

 

^ well that was a nice surprise to see

Things moving along...

 

 

I've wondered (assumed?) that there would be some sort of below ground connector from the hotel to the convention center ... looks like there is one in the photos above, no?

I assumed it would be at street level or somewhere in the base.

There will be an underground connection to the convention center.

July Update

 

  CONSTRUCTION Sheeting the site to stabilize the site will be complete in July and excavation to haul out unneeded soil will continue into August. •10,000 CY of soil are expected to be hauled out to various fill sites. Concrete foundations to support the structure began early July. •8,300 CY of concrete and 800 tons of reinforcing steel are anticipated for the foundations. Underground plumbing and electrical began in early July. •11,520 onsite working manhours are anticipated by the end of July. Tower cranes are in extremely high demand right now due to an apparent “building boom” across the nation, but the construction team was able to secure one. This crane will eventually reach almost 400’ tall as the hotel’s tower is erected. The main function of the crane will be to construct the concrete tower. It will also serve various other functions around the site (i.e. equipment deliveries, miscellaneous structural steel erection, etc.). To date, 301 workers have come onsite for construction.

  DESIGN The design team continues to work through, coordinate, and finalize the design for permitting and construction. •Foundations, underground utilities, and structural steel design drawings have been released for permitting. •A progress print is scheduled to be released by the end of July. •50% construction documents are expected to be released late August.

  SCHEDULE Construction continues to remain on-schedule! Concrete foundations will continue through August into September for steel erection. •Crews are working multiple shifts 6-7 days a week in order to fast-track the schedule. Steel fabrication in Kansas City, Missouri, begins on July 25. •All steel is expected to be fabricated over a 16 week period. Steel erection on-site is slated to begin in September. •All steel is expected to be erected over a 13 week period

If I'm reading this correctly, we're talking a topping off of the steel in January?

That is impressive.

Sounds plausible. Only the 4 story pedestal will use structural steel.

 

That sounds a little quick to me.  And if structural concrete won't be finished until next summer, then what is it "structural" for if the steel is done 6 months before that?  The floor slabs aren't considered structural concrete.

 

The only thing that is steel is the podium, which will include the meeting rooms, lobby, etc... The whole tower is post-tensioned concrete.

Ah, thanks for the reminder!

Why are they going with concrete instead of steel? Is concrete cheaper right now?

Cool

 

Interiors of the new Cuyahoga County convention hotel will strive for an authentic sense of place

 

CLEVELAND, Ohio -- Cuyahoga County's new 32-story, 600-room Cleveland Convention Center hotel will strive for an authentic sense of place with interiors that blend subtle influences from Cleveland's industrial past with adaptations of midcentury modernist design.

 

That's the upshot of the latest set of renderings and plans to be presented Tuesday at a meeting of the Cuyahoga County Council by attorney Jeffrey Appelbaum, who is representing the county on the hotel, to be operated by Hilton.

 

"The mission is to make this a Cleveland-centric project," Appelbaum said in an interview before the meeting. "People will know that the Hilton hotel is the downtown Cleveland hotel. It's sort of a Cleveland industrial-chic concept."

That's not at all surprising for a Hilton. We had our wedding reception at the Hilton at the Ballpark in St. Louis, and the entire hotel is filled with St. Louis stuff.  It's really pretty cool.

Why are they going with concrete instead of steel? Is concrete cheaper right now?

 

From what I remember of materials class and structural design, skyscrapers are mostly compressive forces, and post-tensioned concrete works very well for such a load (concrete is great in compression but poor in tension). Steel is advantageous because it is light and easy to work with, while taking up less room, ideal for large, open glassy spaces like atriums and lobbies.

^Very good Zak!  The concrete is week in tension, hence the post tension steel cables that provide the tensile stregnth to offset that.  In addition, the amount of reinforcement in the concrete floor slabs is significantly reduced in a PT system.  Concrete is tested for its compresive stregnth while steel is tested for it's tensile stregnth.  Not sure on the cost differences between the steel and concrete at this time, but many high-rises, and espessially parking garages, have gone to this.  There is also a benefit to having concrete being brittle while steel is ductile, however that analysis of the relationship between PT cables and concrete runs deep. 

steel work begins this month!

Hey - no fair bringing actual engineering knowledge into the discussion!

August update:

"Steel fabrication in Kansas City, Missouri, is in production and will continue into November.  To date, nearly 70 tons of steel has been shipped to Cleveland and is awaiting erection."

 

Don't we make steel here anymore?

Yes, and it's like totally tubular, man. Like for oil/gas pipes. Whoa, hot tub time machine back to the 80s....

 

Back to the present, I see the elevator core is rising skyward.

We also make flat steel that gets rolled up like giant rolls of toilet paper. Then it gets shipped out to other places that turn it further manipulate it so that it can get stamped, thinned, or whatever based on the particular product needs.

I'm not certain they're making it there though.  It just said fabrication.
