One-week construction time-lapse with closeups: Week 12 of the Ⓢ-series
Вставка
- Опубліковано 31 лип 2024
- Week 12 in the ongoing Ⓢ series, which follows the construction of a new 13-story senior living building in San Francisco. This is a #construction #timelapse with various closeups and "sub-time-lapses" at various speeds, condensing the week of April 20 - 25, 2020, into about 54 minutes.
This episode turned out a little longer than I was expecting, setting a new record for the longest video of this "Ⓢ series". Perhaps I should have shortened things a little more, oh well. There are a lot of long, wide shots in this episode.
We see multiple H's being installed - we know that this channel's logo will be embedded in that building forever! All around the elevator shaft, which might possibly be more than just an elevator shaft, I'm guessing there might be a structural component to it as well due to the amount of rebar and columns around it.
More columns go up (both rebar placement and concrete pumping), and we see the start of the journey upwards as the #shoring for the next floor up from ground level is started on. On Tuesday, the front of the two concrete pumping towers (high rise pumps) gets its top (boom) and is actually used to pump #concrete for the first time. There's a small concrete pour of what looks like the start of a skateboard park, but I assume is actually going to be a ramp down to the lower parking level.
The street is being cut up, although that may not be directly related to this building, it may be part of a separate "Bus Rapid Transit" project that is going on, or could be a combination of both projects, I don't know.
In an unfortunate sign of the times, we see the check-in procedures that the workers go through these days, including having their temperature checked and verifying that they have a face mask. They get a wrist band and are allowed entry if they pass. Although, just as I see out in the general public, I do notice some wearing their masks incorrectly (inexplicably covering their mouth but not their nose, or only covering their chin) and a few not wearing any mask at all - same sorts of things I see anywhere else.
We usually just skip past the nighttime hours in these videos, but this time we watch the security guard making his rounds in the wee hours of Tuesday morning, and on Friday morning at 2 am we notice someone abandon a nice little cart in the alley for some reason, that gets snatched up on Friday.
And various other activities scattered all throughout the episode. Hope you find it entertaining!

Good morning from the U.K.
No better way to start my day.
still watching.. have not missed one yet
If there is an earthquake or tornado I want to be in that elevator shaft. Jeez.
I've started to get interested in your uploads and look forward to seeing the next each week, Great Job .....
I guess im asking the wrong place but does anyone know of a trick to get back into an instagram account?
I stupidly forgot the login password. I appreciate any tricks you can offer me!
@Misael Benton Instablaster =)
@Arlo Musa Thanks so much for your reply. I got to the site on google and Im in the hacking process atm.
Takes a while so I will get back to you later when my account password hopefully is recovered.
@Arlo Musa It did the trick and I now got access to my account again. Im so happy:D
Thanks so much, you saved my account!
@Misael Benton Happy to help xD
Another amazing video for the best construction channel on UA-cam keep up the great work I love your vids
I watch these videos before going to bed because I find them calming. Anyone else? Really liked the nighttime segments in this one!
And before someone asks...the guy was spraying a release agent on those forms so that the concrete wouldn’t adhere to them. Think greasing the pan.
Amazing, looks like a thousand things going on all the same time. Well done construction workers. Stay Safe!
Holy freakin' rebar!
The elevator shaft looks like a bombproof shelter
Yeah it's hell of a bunker!
I'm glad to see the health checks at the gate in the morning, good on them.
Love the Fedex Freight truck, as a driver for the same company I can honestly say "Been There Done That" darn those trees .It's always appreciated when the crew helps you get in and out ,love these videos.
Please continue to post long video
They are very interesting and informatif
The guys using the vacuum after the tile saw reminded me of the movie DUNE when the Spice trader arrived at the Emperor’s Palace.
Hello H C, great video just amazing. Lots going on as always, all the workforce getting on with the job, huge respect to the guys tying in the massive amount of rebar, the woodworkers for preparing the floor and the form's for the huge concrete pour that is coming. It is also good to see the medical checks at the site entrance. Continue to stay safe 😷 and thanks for sharing.
Pretty awesome looking concrete reinforced steel columns they're building.
At 17:00 you see a partially--poured round column that has the rebar cage too close to the edge of the concrete and should be repaired/repoured before any further pours happen. Looks like the dobies shifted when the placed the form and nobody checked before the pour. But I doubt anyone is paying attention as sure don't see much independent supervision.
I wonder why they did not use spacers?!
I love watching this channel with the time lapse construction of hospital
I really love watching that kind of videos.
wow... they don't take half measures with the rebar for the elevator shaft. More steel then concrete.
Robert van Rees, they aren’t just for the elevators. I’m sure they are providing a major part of the shear protection for that part of the building.
A short note of appreciation for all your fantastic time-lapse videos. We're viewing your entire library.. The music for this release was particularly appealing. Cheers from Vancouver, Canada.
Welcome. Be sure to pace yourself!
Another top notch video 😀 THANK YOU 🤪
At 19:53 it becomes clear what the "H" structures of re-bar are for. Notice the large number of bars forming an "X" through the crossbar of the "H." Their diagonal placement is to resist lateral movement, which comes from earthquakes. We saw those diagonal rods being driven into the structure in several earlier closeup shots, but this one makes their purpose clear.
Great progress this week
I love watching this channel here is Brazil
Nice video as always. And really cool the divisions on the timeline with 'sub-titles' nice touch.
I think that YT is doing that. It's new.
Am I seeing things? It took a truckload of concrete to fill the pipe.
Great video ,much appreciated
Good vids keep up the good work.
and the start of the south end goes UP 04/20 10:00 4/22 the first floor form base is laid 1:00 . Now the structure has definition to it , basement ...check....first floor layout ...check bravo ! good coverage!
Ha day 2.... 04-21-20 my Birthday. Good vids keep up the good work.
acabei de ver aqui do Brasil as 23:03 hs do dia 30/05/2020 mais um belo, eficiente e um verdadeiro show da construção americana parabéns a todos e até a próxima......
its a good idea with the climbing harnes and the Nail bags.
Thanks for showing how the concrete got to the tower. I was mystified how that works.
Спасибо автору за такие прекрасные ролики!
You're welcome!
Very nice vedio..
I really admire the accuricy of the rebars works.. Imagin a heavelly congusted steel cage insertion and fixing to the steel dowels smoothly and precisly!!
inanzitutto complimenti per questi video sono molto interessanti dal punto di vista tecnico mi piacerebbe vedere la fine
Hi, is it usual in the U.S. that they didn't use spacers between the formwork and the rebar (e.g. at 6:30 rebar in the tube or at 17:12 the very unequal thickness of concrete on the left and right of the right pillar) ?
Here in germany we need to use spacers almost everywhere to ensure a defined miniumum coverage of concrete over the rebar.
Without being on-site it's impossible to know if it's centered or not. I think there is so much rebar, it is virtually a rigid wall. '' Centering'' it may be redundant or impossible. There may be something we can't see.
@@firesurfer Hi, without spacers the centering of the rebar will be random! And the right concrete coverage is important for the strength of the components in addition to its resistance to fire and corrosion.
@@stainfels1685 After looking at it again, that looks like #8 bar. The braces are more than enough to center it.
Why don't they just steel errect like the hospital?
Красавчик, автор. Прям залипаешь на просмотр. Особенно радуют моменты всяких смешных или странных моментов. Формат недели самое то!
Mais um episódio hein parabéns a todos 🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷
You have to do a compilation video of the stretches they do in the morning to some 80s music. Reminds me so much of those work out shows they used to have, At 2x speed its even funnier.
great video! How many floors in that hospital ? First floor looks very high :)
great concrete flow charts. Wondered about it indeed :)
super.
Long show but a great show!!! Sometimes I wonder are my eyes getting old and slow OR just time lapse is too busy/fast because I couldn’t hardly see where 1 round of concrete was going!!! Also concrete pumping towers are class just interested to see how concrete gets to them!!!Great to see COVID-19 protocols are taken seriously but they they share the same pen signing in.....🤔🤔 oh and I love commenting 😃
Muito bom
Incroyable combien de béton et d'armature de métal utiliser !!!!
An anthill !
Good evening from israel, it seem that the worker are professional and they keep their safety.
🤣🤣🤣🤣🤣 Good morning from Germany, there is nothing safe or profesional.
They built the hospital with steal beams and this one is being built with concrete. How does this work? Which method is better and doesn’t this method take longer to build?
super
Small question re the Bigge crane: do the counterweights automatically move back/forth depending on the weight/reach of the load?
No, they do not move. Interesting idea, though. But the load is moved in and out while the crane is rotating and moving the load into and out of position, so they would have to keep moving in and out continually all that time in concert.
Did not know there was such a thing as a concrete tower um dispenser.
What building is the video shot from. Is it from your apartment and if so where was the hospital construction videos shot from?
Strange how there are no spacer blocks on the steel cage going into the "Sonotube " 5-35 to 6-00 , a shot of the column at 16-13 shows the steel is not central due to the lack of spacers/ wheels
Yes, and that under the special codes for buildings in earthquakea areas. And also the fire resistence doesn't get better with that!
It's externally braced and centered by the long steel poles that you see at 6:56.
@@firesurfer, Those "poles" as you call them do nothing to center the rebar within the the Sonotube columns . all the props do is steady the rebar nothing more or nothing less
@@jeffreyloftus3617 Bull, they definitely center the rebar. That rebar is so thick it only needs to be centered at the top.
This is for the front line workers...!!!
42:32 they poured extra thick footing on already placed raft and that was in slope too what was that for
Parking garage ramp
Where was all of that concrete going Tuesday morning? They put many trucks into that green pump there with the FedEx truck. Where did it go?
They are placing the left third of the rear wall. At about 18:40 you can see the crew work their way out from behind the rear white concrete tower and start working on the area to the left of that tower. Before that you can see the rebar on that section of wall, and a little later it's covered with concrete. They are using the method where they form just the back side, then spray the concrete over the rebar, smoothing face of the wall as the work. They start way in the corner early in the morning, but are too low to be seen because of the forms for the other walls in that area.
What is the building in the lower left across the street, they open early, lights come on at 4 every morning
Tesla store on the corner.
does the crane operator and whoever is directing him work in quadrants or assigned sections? How does he know where to put the different loads? "put it over here" doesn't work when he's up there and you are down there...somewhere.
Radio, Duh.
@@firesurfer I didn't ask how he got the information. I asked how he knows where to move things. "radio, duh" does nothing to explain how he knows exactly where to move loads. "go to the truck on the side" says nothing. "move it to the pillar next to the wheelbarrow" also says nothing. who has the radio? he's a LONG ways up there. how can he see exactly who has the radio?
saying radio does not tell me what type of information he is getting to do his job.
Please explain further how he communicates with the ground and what types of information he is getting to know where to pick up and where to put it down.
@@AffordBindEquipment You should be able to figure that out by yourself. There are several people with radios, I believe they hand off control to particular people on command.
ie; ''Hey, Joe you're up next. Tell him where you want it.''
It doesn't need to get more complicated than that.
What are the white lattice columns for?
Not sure, but I think you're referring to the concrete pumping towers? Also sometimes called "masts". At about 18:00, one of them gets its "placing boom" installed.
This may be a stupid question but where is the concrete coming from at the 37:04 mark. I mean I see it is coming from the tower in the middle of the project but where is it pumped from? Ive never seen a central tower concrete pomp on a job. Great vidoes...keep them coming....I have also never seen a project like this done by placing everything on a concrete base instead of driving multiple pilings as a foundation.
Disregard my question, I stopped the video to ask the question and you answered it in the next 30 seconds in the video...
Usually, they don‘t use a concrete pump truck, but a „trailer pump“. Here are some pictures:
www.bauforum24.biz/forums/topic/31235-frankfurts-opernturm-wachst-mit-betonpumpen-und-klettermast/
Might be a repeat question, what’s the large structure of rebar with the big “H”s, it seems like overkill to me but I’m sure I has a major purpose. I enjoy watching the progress. Thanks from Wisconsin.
The ''H'' look is just a coincidence. The horizontal pieces are for beams.
That is the elevator shaft
Adam Baker that’s what I was thinking, wasn’t sure , thanks
The huge structure of rebar is a set of shear walls, whose job it is to stabilize the building during an earthquake. They have been placed around the elevator shafts, no doubt because that's a natural place to put immovable walls where they won't interfere with flexible use of the floor space.
25:53 White track on right ally arrive in 4pm. Wait 2 hours. Gone loaded. Driver will be angry.
i like nighttime jazz music.
15:53 or so... he does a river tie... that that was just a Midwest thing.... lol
00:25 stretch it out.....get ready for the day
so if u want to steal from a construction site just hide in the middle of the site since secruity dosnt patrols that area 🤔
They have their own separate people.
Uffff first again!!
ok
Xx
first
43:51 👎🏻
Yes, this effects of any kind ruins the details for sure. No need for such effects in a footage like this. I mean, everyone is here for the details, aren't they?
This job is on San Diego
This job is in San Francisco
I am interested in the way you came into this conclusion!
OSHA OSHA OSHA OSHA ... I am scared as a German about all these safety flaws! Looong way to go America! Nothing to be proud of in your Country.
Can you please write down your comments on the safey issues in points? So we can learn from them? This will be helpfull... Thanks
What problems, specifically.
@rats arsed Wrong guy, not enough sarcasm. sooo, lame.
Yeah, we havent cared what you think since WW1.
