Yeah, construction tends to be a young person's game, unless you get into management/supervision or design. There are exceptions, though.

Technically he's inside the the railing system and is not exposed to a potential fall. Just the same, he would have some explaining to do if he had a close call.

I do high rise concrete forming in Toronto and winter we work in -25 c depending on height of building, colder higher up with wind chill and summer 30c this summer I’m in hole 60ft down it feels like 45c+ some days with humidity. Still love the job

In middle east temp is around 50 degree c imagine the conditions there

That seems surprisingly cool for San Francisco.

AH! Great catch.

Strangely they do almost the same things on every floor!!

@@HospitalConstruction it's almost like they're required to do that

@@HospitalConstruction But you manage to capture different details each week!

but .... a new floor every week. It gets interesting after the 12th floor. What will come next? 13 or 14 ;-)

@Construction Watcher - I do try to vary it a bit, but by the nature of things there will be repetition, that's just the way it goes. Some people don't watch every episode though, so repetition isn't necessarily all bad!

Today he has a new job. He controls "barriers and supports"

I suspect he's the safety guy.

Good eye!

Usually the uppermost 4-5 floors are supported until the concrete is completely dried out and as the building grows taller they remove the supports and use them for the new floors above.

Gradually, in future episodes, you'll see them start to remove the supports on lower floors, and then eventually, start doing interior walls and so forth.

“Re-shoring” is typically required for at least two levels below the working deck. Because these guys are nearing a one week cycle(I am assuming this is their goal) the amount is time it takes for cycle is the same amount of time the 2nd deck down doesn’t need re-shoring any more. It’s all about strength of concrete. It typically takes concrete 28 days to reach its designed strength. But only a week or so to reach a strength suitable for no extra shoring. Also, “green”, “wet”, or “new” concrete weighs more than cured concrete. So the shoring is got multiple purposes.

Pre-tensioning is a common prefabrication technique, where the resulting concrete element is manufactured off-site from the final structure location and transported to site once cured. It requires strong, stable end-anchorage points between which the tendons are stretched. Post-tensioned concrete is a variant of prestressed concrete where the tendons are tensioned after the surrounding concrete structure has been cast on site. The tendons are not placed in direct contact with the concrete, but are encapsulated within a protective sleeve or duct which is either cast into the concrete structure or placed adjacent to it. At each end of a tendon is an anchorage assembly firmly fixed to the surrounding concrete. Once the concrete has been cast and set, the tendons are tensioned ("stressed") by pulling the tendon ends through the anchorages while pressing against the concrete. I hope this helps.

Work week in the US for this type of work is typically Monday through Friday sometimes with occasional Saturday overtime (normally paid at 1.5 times the hourly pay rate but can be more (2x or 2.5x in some cases for Holidays, etc.) The schedule of work days may vary due to deadlines or other factors such as weather or material delays as some things such as concrete pours of this scale often may have longer lead-times for the supplier to meet and must occur on specific dates. I'm sure it may differ by region/company/or possibly union rules, but lunches are typically 30 minutes or 1 hour.

Pockets in walls below support the beams that support platform for forms to sit on. I do this work in Toronto.

@@crooked-mouthjr7557 Thanks.

There probably exposed on the lower levels. The square ones will probably be covered with framing and sheet rock.

The round ones will be visible as an architectural element or feature.

Concrete Formwork

To do what exactly !@@crooked-mouthjr7557

That is a gray, PVC pipe commonly used as an electrical conduit. It is definitely not any type of a concrete form. One can only guess why it is being placed within the column.

That's exactly what it looked like , and as you say it's baffling as to what it's going to be used for especially as it was sleeved into another piece of pipe which didn't appear in any previous videos

Actually, it does appear in other videos, we just didn't notice. It's in many of them. you can see it in Week 22 at 37::54, Week 21 at 1::18, Week 20 at 1::15, Week 19 at 11::25, Week 18 at 6::37, Week 17 at 2::48, Week 16 at 0::34, and in Week 15 at 0::36. The earliest I've found is Week 13, where we can see them installing the rebar for this column on the foundation slab, at 3::23. The conduit is in the rebar cage when it is installed. You can clearly see it sticking out of the rebar in Week 14, at 2::40. I can't see where the bottom of the conduit is in those shots. In Week 10 we see the rebar in place in the foundation slab. No sign of conduit to that column under the rebar mat. The best shot of that area may be at 20::57, where there is no sign of conduit, though the view is obscured some by the tree. At 46::49 we can see the rebar for the base of the column coming out of the slab. Is that a conduit in the middle? If so, why isn't it visible at 20::57?

?

It’s set before concrete is poured, if existing structure then drilling and epoxy is needed to add rebar

It says right on the top of the description - 13 stories.

@@constructionwatcher5381 thanks mate

I don't know the GC. Like it say in the description at the top, it's in San Francisco.

Handel Architects did the design. handelarchitects.com/project/1001-van-ness is the web page for the project. Oryx Partners is the site developer and they drew the permits. The site may have changed hands at some point, with Atria Senior Living now the owners.

weird disturbing comment !😐

@@amazingpulsation9325 This is not strange for us, such is life in Russia. Everything is good in America, but we are beggars here.

Сергей Иванов Lmao nothing is good in America...

@rats arsed I have a job, but in Russia they pay $ 411 per month for it.

@rats arsed I don’t buy vodka, I don’t know how much it will be, but you have to pay for an apartment $ 69, 1 liter of gasoline $ 0.6. We still get paid for work.

Ну так кто вам запрещает строить!?
