Big money and easy work.

@@sydneyshinshi easy money perhaps. But I'm sure the stress factor is way up constantly maneuvering and picking and setting things all day long, every day. Would be interesting to know if they have the same operator every day, or have substitutes. Just the thought of being in that cab 8 or 10 hours, every day......

He knows how much a tower moves.

Can someone please comment my comment!

My ex wife used to test concrete in the middle of the night in Cairo when USAID were building pyramidal hospitals there back in the late 80s, iirc. When she found they had used sea sand instead of the proper construction sand, she could tell because it contained shells, she made them dig and chisel out the whole night's pour. In that case the concrete supplier got to pay the bill for the work and then supply new concrete to the required spec.

In that case wouldn't they need to remove the entire wall, not just the top 2-3'?

Lol I see that that is funny

I wondered if anyone would notice that except me

Learned a new word today! Hadn't heard that word before.

Lool that’s a one man job no need for a apprentice there’s no drops or Any need for cutting.

Yes, notice when they pour the vibrator to make it settle. That would push the rods apart if they weren't tied together. The scaffolding is used until the concrete is set enough to support it's own weight then it can be removed. This was a major factor in the Hard Rock Hotel collapse in New Orleans, when they went to remove it, it was buckling under the weight of the concrete that couldn't support itself.

usually ties with zig zag pattern leaving 3 or 4 in between

Removing the scaffolding depends on the concrete mix used. Usually takes 2-3 weeks but if you use rapid hardened concrete mix, you can achieve the 90% strength in 3 days

Have you read Hospital Construction's description, directly under the video? The very first line answers your question.

The ride on trowels will be making an appearance in a future episode. I would like to ride on one someday...

I think you are referring to the central core, which will be an elevator shaft as well as a major structural component.

That structure of heavy re-bar is a structural element designed to resist earthquake loads, which will try to move the bottom of the building out from under the top floors. If that were allowed to happen those skinny concrete columns, which do a good job of holding up vertical loads (the weight of the floors above) would do almost nothing to keep the upper floors in place below the moving lower floors. That would cause those columns to break up, and the building would fall. The strong structural walls are designed to force all the floors to move horizontally as a unit, and thus avoiding bending and breaking the skinny columns. They have to be very strong, as you can see by all the re-bar. A strong earthquake can generate horizontal accelerations on the order of one "g," that is equal to the force of gravity. To resist that load the shear walls have to be able to support a horizontal load in the order of all the weight above them. As an approximation, we can think of it this way: if the building were turned on it's side, supported only by the foundation, those walls would have to be able to keep the upper floors from falling to the ground.

@@constructionwatcher5381 thank you, it does look overbuilt. In the past several videos I could see a new bar added here and there. Was somebody looking that close to see a missed 4 bar half way up the side toward the camera?

I can't and/or don't capture/show everything

Hospital Construction Sorry, I’m not complaining, I was just thinking out loud as I saw blue post tension cable on the upper floors but not on this above ground lower floor.

@@escapelevel1 No worries. Post tensioning isn't needed on some of the lower floors.

It looks like below that is the entrance to the parking garage

Probably a stairwell between floors. The concrete was probably poured into vertical forms forming the stairwell walls.

That’s a shotcrete pump for a crew doing some interior walls of some sort. They don’t move concrete quite so fast. You can see them set up on Tuesday morning on the street to the right rear and they work on finishing the back wall.

The entrance to the parking garage is on the opposite side of the building, half way up the street on the right. See handelarchitects.com/project/1001-van-ness -- the 5th image down shows it clearly.

@@constructionwatcher5381 wow! That's a beautiful looking building!!!

prob multiple layers of plywood glued together to desired thickness.

He's cutting 2 sheets, probably mdf or plywood

At 38:20 you can see a good close-up of one of them in place. Clearly two sheets of plywood, together about as thick as the 2 by 4, or 1 1/2 inches. So looks like two sheets of 3/4" ply.

Wellington boots for men on Amazon - those ones?

@@peterdowning5846 Thanks, will look there

I don't have access to the final plans, and the only actual plans I've seen are from years ago and likely out of date. However, this may give you a general idea: handelarchitects.com/project/1001-van-ness

@@HospitalConstruction Thank you. These drawings give me a general idea. Perfect

i _think_ it's because the square ones will be hidden inside walls, and the round ones will be exposed.

@@notatoad after a big earthquake in albania I had to check for column damage in her apertament building. It was hard knowing which one was an actual Column so this is important information for me and others

so that the steel does not lie against the wall but is always surrounded by concrete

Dunkelwolke a ok...thanks

There should be a "Hospital Construction Channel" flag there, of course!

@@HospitalConstruction go put one up at night!

Probably as many as are mentioned in the very first line of the description, right below the video.

Everything is listed in the description.

You beat Hospital Construction to it this time. Congrats. :)

@@davidsilvera7436 He, he, he.
