One-week construction time-lapse with closeups: Week 27 of the Ⓢ-series, including concrete pours

[@Bill_N_ATX]

Just in case anybody is wondering. The black iron pipe going in the building on Wednesday is for waste water. You can tell by the sanitary sweeps instead of squared off tees. If you see square tees, it’s supply water or fire suppression pipes. If you see tees that are curved, that’s for waste water that’s not under pressure and might have solid objects and other materials like toilet paper you don’t want to obstruct the flow of the liquids.

Unfortunately this time so late and thanks again for another great video. I'm looking forward to the next one. Always seeing a lot and new things. That's why I watch the video at least twice ;-) Greetings to everyone and especially to Hospital Construction. You're doing a great job thank you.

parabéns a todos por mais um show de eficiencia da construção americana, e parabenizar também o operador de GUINDASTE que é muito bom e habilidoso e que quase não aparece nos vídeos mas que é suma importância neste tipo de obra, um abraço a todos e até a próxima semana...

[@davidnull5590]

Rough translation from Spanish: congratulations to everyone for another show of efficiency of American construction, and also to congratulate the CRANE operator who is very good and skillful and who hardly appears in the videos but who is of paramount importance in this type of work, a hug to everyone and even next week...

[@jetjock86]

Thanks again for another high quality and enjoyable video. I know nothing about concrete. I am amazed at the speed this concrete seems to initially set, support the drive-on floats, achieve a super smooth finish and then have construction materials dropped back in via the crane. None of the garage/shop builds I've seen ever progress like this. Can anyone speak to the type of concrete or pour methods that achieve these results and how they differ from smaller residential type projects?

[@ShouldersMoondog549]

Pretty cool the camera on the crane hook!! Now the operator can see what he's picking!! I sure hope that they get the personal elevator installed soon!! I'd be tired by the time I got to the working floor!! :)

Would love to see footage from that camera angle.

[@constructionwatcher5381]

Thanks again for another great week with amazing editing, as usual. Any chance of getting a 1x view of the tower crane tower moving as it swings around with a load? At high speeds we see it move quite a lot, but it's difficult to see how fast that movement is in real time.

[@HospitalConstruction]

I'll keep that request in mind. The crane actually moves fairly slowly, as often does the attach and detach process, so including much of that at normal speed would increase the video length quite a bit. But maybe there could be a separate video or something, don't know.

[@davidhamann1300]

love the music this week, some great mellow tunes. if possible, could you get them cutting the cables after tension we have seen all steps, except for this one. Thanks and keep up the good work.?

[@constructionwatcher5381]

I was going to post the same thought. We have several great shots of preparing and tensioning the cables. Then at 42:12 we have a good shot of grouting up the holes. But what we haven't seen them cutting the cables off, and whatever they do that creates the little dimple you see before he fills the hole.

[@MrPapiray23]

Wow that concrete set fast, they can put scissor lift on it only in a few hours.

[@nickboomer4566]

Cement is only one of the materials used to make concrete.

[@Bill_N_ATX]

Nick Boomer , his point is still well taken. Yes, it’s a pretty hot mix. It’s not your average house slab mix that gives the crew an hour to get around to troweling it off. This one is full of plastisizers and other additives to let it pump smoothly and set up fast. Plus they have the advantage of working in the cool side of the Bay Area. It’s not a hundred plus degrees so they aren’t playing Russian Roulette with their mud.

[@maximunpayne92]

the might have a hardener in the mix so it sets faster

[@nickboomer4566]

My point was more that it's not cement. It's concrete.

[@sydneyshinshi]

@@nickboomer4566 Yeah we got your point

[@jims146]

How much is the smoke from the wild fires effecting the cameras to record the construction?

[@HospitalConstruction]

Because I'm a month or so behind real time, you'll start seeing effects from that in a couple weeks. The first thunderstorm that started it all occurs on Sunday, the last day of the next episode (Week 28).

[@itsallspent]

I think it be a prank . They nailed my lunch box to the bench one day .

[@HDRONES]

Parabéns pelo excelente trabalho! Congrats from Brazil for the great job! Could you explain how many cameras are used to capture the images and what software are used in video edition? You really do a great job! In your first videos I've watched I thought you used just one camera picking up pictures at a time interval, like 15 seconds. But now I imagine You capture real video and apply super speed on it. Very very good!

Any know how far over budget they are with all of overtime? Pouring the concrete and the steel guys working till 6:00 or 7:00 P.M. That is real expensive.

[@gilron9585]

great video! what happens if you don't do the pre tensioning ?

[@davidhamann1300]

the slab would eventually crack and crumble from the load. concrete is good under compression, not so good under tension. the blue cables help hold the slab in compression.

If it is who I think you're referring to, I think it is an electrician who just happens to be standing there for a bit. The guys doing electrical and conduit work are usually the ones with the blue helmets. (Although, they don't have a monopoly on blue helmets.)

[@user990077]

Can anyone out there tell me why they are using concrete as opposed to steel? All the formwork, rebar and post tensioning cables seem so labor intensive I see little advantage with concrete. +

[@davidhamann1300]

i think it was just the way they designed it. both types are sound, it just all comes down to $$$. have you watched the first hospital being constructed? if so, the MOB is a combination of concrete below grade and steel above.

[@user990077]

@@davidhamann1300 Yes, I did watch that earlier series. They did not have to build the temporary deck, etc. Thanks for info.

[@jeffreyloftus3617]

Two points where did the pump section come from 42-50 and where is the access from floor to floor given that there is no footage of stairs having been put in yet

[@constructionwatcher5381]

The pump towers are fixed height, maybe 3 stories or so. They are just lifted up and the base anchored to a higher floor. There is a good shot of this three or four weeks back. There are no doubt several construction stairways. One is visible at 14:25, behind and to the right of the crane tower.

[@HospitalConstruction]

The lower floors have stairs installed already, they're just not really visible from our vantage point. One of the early episodes in the series (I don't remember exactly which one) showed some of the stairs being delivered, and in fact the next episode (Week 28) will also show some stairs being delivered. The upper floors have access by ladders. In some episodes in the future I hope to be able to catch shots of stairs being installed, but so far have only gotten a tiny snippet.

[@constructionwatcher5381]

The top of one of those ladders is visible at 8:27. It's barely sticking out of the box that one worker has his left hand on, to the left of the two porta potties.

[@CapApollo]

90% humidity.... wow..

[@HospitalConstruction]

Because of the fog and being surrounded on three sides by water, San Francisco tends to be cool but humid. There are occasional exceptions, such as the period coming up soon when the wildfires start.

[@gilron9585]

Thanks again, Just curious. The same workers are going to work inside the lower floors of the building later ? (after all upper floors are done).

[@informeddissident]

Some of the companies may have additional contracts beside just the base work. I've worked many projects where the concrete carpenters also provided labour until completion. Most of the work is specialised though and requires separate contractors

Look how shitty the rebar amount is in the first hour pour on Monday!!!! Looks like it was missing 99% of should have been there but yet there just poured!!!!

[@constructionwatcher5381]

On these floors the reinforcement is provided by the blue post-tensioning cables. The rebar is concentrated around the columns to transfer the floor load from those cables to the columns. Look back a few weeks and you will see the same pattern on all the residential floors. They used a different design, with lots of rebar, on the lower floors which will be commercial space and "public" space for the residents.
