16 weeks and the first floor is in. Hats of to the organisation of this operation and to the workers. It is plesure to watch the workmenship of differend disciplines working close together in a commen goal. 👒 👒 off!!

[@silentepsilon888]

Thank you for all your hard work putting this video series together. It has been interesting and fascinating to watch the progress and little setbacks since day one and I am looking forward to many more interesting weeks of progress to come. ;)

Considering how much fun I had screeding just one 11'x11' slab, these guys do an amazing job with no guides but the MK-I eyeball.

[@malcolmross3782]

Hello H C, another awesome and busy video, that was a massive amount of concrete. All trades working flat out but a big shout out to the steel workers on the lift shaft and the concrete finishers after the big pour. Thanks for all you're hard work producing the video but remember to stay safe 😷

very interesting layout, uneven floors and interesting walls pop up everywhere

@@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......

Great series! The Sonotube round column forms is confounding to me! How can that be economical vs reusable steel or fiberglass forms? Maybe it's due to site storage limitations.

[@joebledsoe257]

Re removal of wall concrete, sometimes the concrete doesn't test right so they have to remove and replace it. Supplier or its insurance has to eat the removal and replacement cost.

[@cageordie]

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.

[@pricerials5355]

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

Not anybody sitting around or having a smoke break. Seems to be small groups, 10 or so working with their section of the project. I have not seen an identifiable boss or supervisor. Worker seem to know jobs well and work flow is very organized. I have seen no injuries or accidents.

[@gyprocman8163]

With (meyer629)....also see if the site super on the next job put a camera on the boom (trolley hook) looking down sync it with another camera looking at the job. See what happens.

[@AffordBindEquipment]

someone please explain the rebar tying. does EVERY place they cross need to be tied? There can't be much structural benefit from the wire, so is the wire only to hold it all together before the walls get poured? Also, has the scaffolding been removed from the floor below already and it's being reused here, or does it stay longer and how long?

[@pricerials5355]

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.

[@zireael531]

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

[@ihsanabdulhadi7262]

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

[@TrashBulldogProductions]

Do you know how tall this building is going to be? Since they installed tower mounted concrete pumper booms it looks like this will most likely exceed the California Pacific Medical Center in height. As to the concrete pours I am surprised we have not seen any of those Ride on cement trowels like we saw during the CPMC construction. On the topic of cement it was about time they used the booms to fill up the column casts instead of the bucket. As always great video!

[@constructionwatcher5381]

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

[@HospitalConstruction]

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

[@longcaster]

HC, what is that re-bar cage they are building? Since this a senior citizen building is that going to be the pharmacy? It will take an effort to get in that without the combination or key.

[@HospitalConstruction]

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

[@constructionwatcher5381]

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.

[@longcaster]

@@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?

[@newsnowfresno6873]

❓❓ To the left of elevator shaft is a 2 x 4 wooden fall railing covered with orange plastic fencing. I think it is still open to the floor below in that area. Earliest part of video, during the large floor pour, multiple truck loads of concrete were offloaded just outside the orange fencing area. I saw no concrete pumper or hoses in that area so I think that concrete was going to a lower floor. Anyone have any idea where those multiple concrete loads were actually going❓❓

[@redthunder1202]

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

[@mcgyver272000]

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

[@Bill_N_ATX]

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.

[@constructionwatcher5381]

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.

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

Question: in the thumbnail for this video a worker is cutting a circle out of wood. It will be used to secure the sonotubes at the top and bottom. What kind of wood is it? And about how thick? It's really thick. Thanks.

[@julianhurley1985]

prob multiple layers of plywood glued together to desired thickness.

[@marcuswestin5613]

He's cutting 2 sheets, probably mdf or plywood

[@constructionwatcher5381]

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.

[@escapelevel1]

Thanks! Did I miss something or was it not necessary to post-tension this floor?

[@HospitalConstruction]

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

[@escapelevel1]

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.
