the top floor of the garage is getting a waterproof top before the concret is poored

What "concret" are they "pooring"? The slabs are already in place.

I should have thought about that more, it makes sense that the wearing slab will be poured on top of the sheet membrane waterproofing.

In precast concrete garages you can have topped or un-topped or even pretopped precast structural concrete units, such as a double T or a hollow core components. It is common for a wearing slab to be placed to protect the structural members from damage or the "wear" that occurs from cars and thier acids and oils etc from finding their way into the concrete and effecting the reinforcing in a negative manner. Again have not seen the plans to know what system they are using. A section detail would do nicely but anyhow... Thanks Anonymous for the jolt to my memory!

Is the Oklahoma Tower a re-named Bldg.?

So how close are they to be done with the basics of the parking garage? The construction cam is a little too far to the left to tell.

From what i have heard, they will be opening the first 4 floors of the garage up the middle of next month. And as of the today they will be working around the clock, they want to get the base of the tower started by feb 10.

The garage is nearly up to 8 floors all the way north. They are starting to put in the posts for floors 9 and 10 as we speak. Also, they already put some side panels on the north side - I guess because they have limited access to the alley behind the Library.

No. It opened somewhere around 1981-82, with that name.

Good idea.Front row seats

It has a gravel top to it. Don't know if that helps you any..

Today I was walking by as one of those trucks was backing in with a load of those slabs. It looks like they are only a couple inches thick! Of course, they have supporting ribs that are much thicker,but I was surprised at how thin the surface was.

MadMonk, I miss your time lapse videos!!!!

Yeah they are often two or three inches. PCI has a construction manual that shows the components and design strategies that are often employed when building a precast concrete parking structure.

Here is the link to more than you ever probably wanted to know...

Wow! That's some dense fog this Tuesday morning. I can't even see the image ;-)

Thank You for moving the CAM!!!! We now will be able to focus on what is transpiring about the base of the tower and its piers as it becomes more formally defined by the foundation as work progresses! That made my day!:woowoo:

I'm confused! I thought the main tower was going to be in front of the west garage ( ten story garage). Is it being constructed where the cam is aimed now?

Yep, that big circle is where it is going to be. Look at the drawings on the Devon Construction thread to get a feel where the parking garage is compared to the tower.

Here's a great drawing of the site:

Thanks for the drawing. That really helps me to understand what's taking place with the construction. Thanks again!

Last night they poured a portion of the wearing slab on the top level of the parking garage. They have been doing the same on the levels below previously. It would be cool to see the west side of the site if anyone happens to be over that way I know that someone had mentioned that they were now expanding the garage westward. The pace has really begun to accellerate as the crews are now there around the clock not just until 11:00PM as they were for quite a while. I have regularly seen them there after 1:00AM and not just a skeleton crew, I counted 12 guys on the roof of the garage last night when they were pouring the wearing slab and that is all I could see but there was at least the two main drilling rigs running and a concrete pumper and some guys in the bobcats running around so the site was humming!

I can't really tell that they are doing much with westward expansion of the garage - certainly nothing substantial that you would notice, although they may be doing some stuff around the corner that I can't see.

I usually get into office between 4:30 and 5 AM and they are there working. The area is lit up and the workers are buzzing. I love sipping that first cup of coffee with lights out so I can see the action.

The West side of the garage is going to be a add on to the garage now. They are expanding the garage pretty much out to Hudson. 10 storys as well.. It is just a open pit right now. They are boring still and getting the West side of the garage wall ready to add on.

Hi Anonymous, thanks for the update. Are you working on this project? You sound like you have at least worked construction before. Again thanks!

Are they still working at 12:30?!?!

Well that is pretty much what I thought, but someone the other day acted like they saw them starting to put up columns - I hadn't see anything of that nature.

So if they start feeling like the government is spying on them, they're really not all that paranoid, huh?

Pictures of the west side of the garage, showing the construction on that side, have been regularly posted on the other Devon thread. They are current, up to last week.

Jut because you're paranoid doesn't mean they aren't out to get you.

Hopefully, they are all good union members!

The camera is stuck again!

I hope the "Van" is not.

I think the van is full of listening devices.

Yes i am on the site alot. I can't say who i am, it will get me in a lot of trouble but i will up date what is going on when i can..

Just wave every now and again. We'll blow up the picture frame and figure it out on our own
:sofa:

The white van leaves every morning about 2:30 am or so and comes back around 9am or so.

Is the Red Crane in between the parking garages gone?

Now we are starting to see some serious excavation! That is what I am talking about!

Does anyone have a guess/answer on how much deeper the dig should go? I know we are all expecting the tying of the foundation in the next few weeks.

They have removed the access ramp into the pit area that they have been using until this morning and are currently excavating it out level with the remainder of the sight. They are now accessing the site from the West side and driving along the south of the Parking garages. I don't know exact timelines but this tells me that we are getting very close to seeing them tie the mat foundation for the tower.

Quick question! On the left side of the pic where the two pipes are laying on the ground near the tower foundation area, is that a rebar soon to be concrete column sticking out of the ground? If so, AWESOME!

It is just laying on the ground ready to be picked up and put in a hole. They have probably drilled 15 to 20 holes and put rebar in there already. They just fill in the holes and cover it up so they can drive over it.

Oh well. Thanks for the reply though! I'm just so ready to see something coming up out of the ground!

Me too!

What NDmoore said is exciting, because those "holes" have the structural steel reinforcing inside and have been filled with concrete forming the structural piers. So where as they are not protruding from the ground at this point as soon as they are done drilling and pouring the piers, they will expose the tops through excavation and that will show all of the piers and they will then be able to tie into them with the mat foundation reinforcing steel and that will be the significant step (once poured prior to structure emerging vertically from that point.

Remember that there is a lot of the structure in the ground already as we speak!

A couple pics of that area from the east garage:

Thanks Madmonk for the pics! I have been dying for more detailed shots of the area! I am curious if anyone knows what the shaft looking thing is under the dozer in the first picture. Is is a remnant from the old parking garage? Or a chase or vault that will be part of the new one? Anonymous? Anyone? Just curious...

And we have lights on the added Stairs on the Garage...

I'll bet the white van doesn't leave toNIGHT. I'll look for tracks tomorrow.

I guess the mail "Must go Thru "

:woowoo:The mail "Must go Thru"....!!!!

Dadgum, it IS gone. I see though that it has NOT returned. Hmmm.

Wonder if it's stuck on the side of the road somewhere?

Probably at the bottom of the ramp, I'd imagine.

Somebody parked in the white vans spot!

Those Bastards!!

Is it just me or does anybody else see the optical illusion when looking at the two parking garage structures?

Because of the angles it looks like if you laid a ruler across the garages it would lay flat but it just happens to be the distances in the images. We all know the West Garage is twice as tall as the East Garage, but yet, in the image they look the same height. I think my eyes are messin with me only!

Perspective is a funny thing, Notice that if you focus soley on the smaller of the two that it being closer seems bigger than the 5 stories of the the original part on the larger expanded garage to the west. It is just perspective that does this. Fun though huh?

I am glad for one to see activity return to the site! looks like they are going to attempt pouring some more piers!

Its back!!
