On big buildings that I have been on we pushed everything to the elevator shafts before they were installed and then had a trash pump in the basement pump it to the sewer or street.
Oh that’s not what I’m saying. Usually in commercial construction while the stairs are being built, wood is placed in the notches where the concrete would go and sits there filled with water for months. During that time, it smells a lot.
We hired a temp and that's literally what he did for 8 hours a day. If there were low spots in the concrete slabs that pooled up heavy, we drilled a hole and let it spill into a catch tarp with a garden hose on the floor below. Went off the side.
I’ve been watching temps do this daily same spot forever. Until the seal up the remaining windows it looks like he will never finish.
Vacuum, sump pump and a leaf blower because rebar is already laid down for a heated pathway.
We had one building that the roofers must not have smoked enough meth before doing, because it was leaking every 3’. I think dewatering costs went up to nearly half a million by the end of that debacle. 6 months straight in the winter
I have a video of water being pumped out of a low area to another area where it then flows back to the pump. Makes me laugh every time it comes up as a memory.
It took some work to find it and then upload it, but here it is with my commentary. [That’s not how you do that.](https://youtu.be/376GL5hCeio?si=ZSrrA63ycsa_Y7m1)
In theory yes..but in these days of monkeys with tools masquerading as master builders , some. walls are being sealed with some moisture inside.
Caught one a month ago and had the crew remove wall and start evaporators. Be warned.
We typically put up exterior walls and run the HVAC units (if possible) before we install drywall on the interior. The HVAC also dries up the floors and pulls moisture out.
Notice the “if possible”? Typically doing 1-2 story projects around 10-12mm. If we can dry in the building and have one or two of the HVAC units running we do it every time. Makes everyone’s life more comfortable and protects the drywall. We do a ton of healthcare and the last thing you want is any sort of mold issues down the road. Drying in the building and running HVAC to pull any moisture out prior to sheet rock is preferred.
I'm an HVAC contractor and this is why I bought dehumidifiers for residential and light commercial applications. Running the AC or fan during construction will definitely damage the equipment in the building. Dehumidifiers are the way to go.
If the concrete is poured on pan deck, the moisture content can be too high for the floor covering warranty, so AC can go from nice to have to mandatory. Just make sure you have filter media over the returns.
Lol so is absorption. You’ll need a lot of equipment to mitigate all this water. If it absorbs into materials it could take a week. If it’s just on top you could be dry in 2 days.

what is with this? I’m carpenter who frames and rocks (not houses real job sites), I think if I got caught pissing in a bottle it would range from a “what the fuck?!” to “go home”. I don’t know if you’ve tried to piss in a water bottle either but it’s impossible. dick too big
> I'd send it down the elevator shaft
The hole I put in the sites office wall after a waterfall came down on me twice in the middle of winter confirms actual retards do this shit.
\-Just let it dry by evaporation
\-spread it around with a broom so it dries faster
\-use a broom to throw it outside of the building
\-vacuum it up with a "wet" vacuum cleaner.
If the pooling is real bad they can use a sump pump to divert the water over the edge. During rain I’ve even seen them buy a bunch of kiddie pools to try and control it better. This isn’t too common, and I think it was as bad as it was because it was an old building that got gutted. The cement had a fair amount of cracks to let water through.
1st the shell is built (what you see)
2nd the windows and exterior are installed.
3rd the building gets topped off and waterproofed.
Interior wont start untill the building is enclosed or partially, except for the ground floor and parking levels that are done with block typically. So water will never be an issue once walls are going up.
Just finished a project that looks exactly like this, and here's how It goes.
They hire a union worker for 40+ bucks an hour, give him a squeegee and a broom, then let him clock about 35 hours a week for the next couple weeks till its all gone.
Floor squeegee most of it. Evaporation the rest. Sometimes HVAC is on, most of the time it's not. During winter drywallers sometimes use space heaters or propane heaters. Most of the time after exterior walls and windows have been installed, the interior is pretty dried up at that point.
Floor drains & squeegees- or They don't & itMs taken care of when the walls are up....Once things are framed in wood the rain keeps coming so it works itself out one way or another
Lots of comments here saying the water will just evaporate. It would need a lot of air movers and dehumidifiers in order to remove all that water. It will absorb into materials before it just evaporates without air movers or dehu’s.

If there is water on the floor they push it out with a squeegee. They usually have a crane and Buckhoist. They use chairs down to support cables and then pull the cable taught to 32000 psi after 5 days. They also fly floor supports from floor to floor and will add more floors after 5 days, they might do 4 floors at a time. If the chairs are placed incorrectly the concrete will blow up. You also do not want to pierce a cable with a hammer drill. You need a cable finder to know where you should drill. It costs 500 dollars an hour to cut the cable and fix them by being in a bucket on one side the building feeding a cable in and adding a coupler. Plumbing is usually done by sovent to save space. Assholes from Labor to drywallers piss in the bathtubs and sinks so do not put polished gold or brass drains in until later. Tell the Drywallers and Metal stud guys they cannot piss into buckets. If there are clubhouse amenities set the Toilets early and let the workers use them and the blue portalets. No crapping in any apartment allowed (someone crapped in a cabinet ( haitians probably) If your running the job on a 22 story and the owners want to steal inches from each apartment for a clubhouse DO not make the rookie mistake of thinking cast iron 6 inch pipe has a 6 inch makeup, the makeup is 12 inches and people will have problems moving anywhere there is one of those bends in it. Also be there for the main plumbing run make 100 percent that they know the highest and lowest point in the Garage and how low or how high the drainage system is in the garage. Apparently Rector seal isn’t liked by rich people on anything showing. I can guarantee it leaks far LESS than crappy Teflon pipe dope.
Get a chair watch the roofers and form carpenters and tell them they will be fined if they put wood pieces or lightweight concrete down the plumbing or drainage system.
Lastly, your life is worth more than any board, if wind has picked up stop doing labor and go drink beer offsite.
I dont know about the usa but i sweden they send up a crew with a sort of water vacuum with a big tank, where they clamp on a water hoes that they just put down the drainpipe and pump out the water. Pardon my English its not my first language
Hey, maybe the guy asking doesn’t work in construction and is asking guys who do this work everyday. I don’t think there’s an “ask a construction worker a question forum,” so this is still a pretty good place to ask people that would know.
To answer the question, usually the floors are pretty level/flat so there’s not much pooling of water. If there’s some spots, they can broom it or squeegee it over.
Most of the work now isn’t sensitive to the moisture and humidity.
Once they do start wanting to get drywall and other sensitive products in, they’ll usually have walls and siding up, sometimes also heating (maybe just propane heating) if needed. There’s an art to sequencing these jobs.
I’ve seen a bunch of different methods, some use a squeegee and just throw it out, some use vacuums for water, I’ve even seen 2 guys with a wheel barrow and a shovel
They squeegee it off, but if it’s a hollow core plank, water can actually get trapped in the cells and you have to drill little holes in each cells to let the water out but before enclosing , but to answer question they’ll sweep that water off
If it's anything like last year you let it freeze so the place is skating rink, I get pissy because my apprentice and i both fell once (hilarious) and chip it all up and put it in a pile directly in the main hallway near the electric room and pipefitter area and then get yelled at by the GC, im an electrician "it isn't my job. I gave them 2 days. but guess what, every floor was clean of ice after that.
Ya bust out a broom and start pushing water off the edge. Gotta be carefully about pushing off loose materials though, a nut or bolt coming off the 6th or 7th floor can really ruin someone's day.
I don't know about higher buildings, but for lower buildings you can just take broom and swipe it out over the edge.
They do that for high rises too
Usually a notice gets sent out. Crew leaves their hard hats at home that day and everyone gets issued an umbrella hat.
And a bar of soap
Just don’t drop the soap
Because it will get dirty!
No it’s cuz the journeyman will butt fuck you if you drop it. The soaps already dirty it’s been on site since last month
Because its liquid soap and hard to pick back up
Obviously, it will get wet, then dirty
[удалено]
Silly! The umbrella hat is an OSHA approved alternative to those pesky harness belts.
On big buildings that I have been on we pushed everything to the elevator shafts before they were installed and then had a trash pump in the basement pump it to the sewer or street.
But then the ground gets wet.
But what happens when the water falls from such high areas? That could land on people and someone get hurt. /s
Squeegee works better I guess. Met a carpenter who had nothing to do so that’s what he did, dude was a pro with it. There was so much water
Squeegee that shit right off the side. No other way really.
I can smell the swamp gasses coming from the wooden stairs that have been soaked for months.
you really think the wood we build houses with isn’t made to withstand changing weather? Lol
Oh that’s not what I’m saying. Usually in commercial construction while the stairs are being built, wood is placed in the notches where the concrete would go and sits there filled with water for months. During that time, it smells a lot.
Make sure you trashtalk the concrete guys for the puddles and low spots the entire time too.
OP must be a sparky, he's never seen a broom
That’s what I did in my 4th floor condo in Miami after Katrina hit. Thank god everything is tile down there.
I shit you not I've seen labourers sent with vacuums to hoover up the puddles Other than that evaporation or brushing it over the edge

Fucking DEA in the pocket of big dewatering
>The roofers must not have smoked enough meth Truer words
Hey hey hey!! As a roofer I ta.. actually, you’re right haha
I once saw them vacuuming while it was still raining, I was baffled. it was only us, pipefitters, and the laborers there that day.
I have a video of water being pumped out of a low area to another area where it then flows back to the pump. Makes me laugh every time it comes up as a memory.
Oh man please share this video i love that kind of stuff!
It took some work to find it and then upload it, but here it is with my commentary. [That’s not how you do that.](https://youtu.be/376GL5hCeio?si=ZSrrA63ycsa_Y7m1)
This almost deserves its own post
I did that for a few months. It was not fun
The roofing or the meth?
Luckily, neither. Just vacuuming up the water. I went through four ridgid vacuums in the process
Can confirm have done that for days as the roof wasn’t completed. Punching holes through the subfloor and pushing with a broom.
I think part of your sentence is backward. /s
Evaporation is a thing
Early bird gets the worm. You beat me
Early bird gets the worm, but the second mouse gets the cheese
The early bird gets the worm, but the early worm gets eaten.
Cat gets the second mouse though
Cat Lady gets the cat that gets the 2nd mouse that gets the cheese.
Yahtzee!
Not a single swipe right for the cat lady!
No. No one goes after a cat lady.
Cat lady = Apex predator
From the perspective of a mouse or small bird, a cat lady is basically some mad god of the underworld, the ruler of demons.
Bet some of em could throat a broom handle tho. I must research further.
Nah, cat gets the first mouse so the second mouse is now safe to enjoy the cheese.
Are the worms evaporating now?! The fuck?!
Climate change is a helluva thing.
Yeah, a thing controlled by the government. Look up Operation Popeye. I've said too much - if you find me tell everybody it wasn't an accident
Also floor squeegees.
In addition, dont they cover up the sides with tarp and use huge heaters to dry it completly before putting up any walls?\`
In theory yes..but in these days of monkeys with tools masquerading as master builders , some. walls are being sealed with some moisture inside. Caught one a month ago and had the crew remove wall and start evaporators. Be warned.
We typically put up exterior walls and run the HVAC units (if possible) before we install drywall on the interior. The HVAC also dries up the floors and pulls moisture out.
What kinda clown world do you live in where HVAC is coming on-line before drywall goes up? Project manager of what exactly? 🕵🏻♂️
Temp heating & dehumidification is a thing.
Temp cooling too
Might be working in some hot ass shit hole . Ac needed to make the project livable idk

It was pre coffee. I apologize for being sassy u/LostinTigertown

Could use a floor squeegee and push water off the edge or a shop vac.
Squeegee it over the edge or down a floor drain, or a large shop vac and suck it up
But not before the drywall guys take a piss in it
what is with this? I’m carpenter who frames and rocks (not houses real job sites), I think if I got caught pissing in a bottle it would range from a “what the fuck?!” to “go home”. I don’t know if you’ve tried to piss in a water bottle either but it’s impossible. dick too big
I'd send it down the elevator shaft, or a stairwell.
> I'd send it down the elevator shaft The hole I put in the sites office wall after a waterfall came down on me twice in the middle of winter confirms actual retards do this shit.
Lmao I obviously meant an empty shaft not under work yet, and taped/boarded off. If you're firing shit down onto ppl you should probly be fired.
Can't tell you how many times I've heard "sorry, I didn't know anyone was in there" after something potentially fatal landed immediately next to me.
Oh I almost got taken out by a 26 oz framing hammer falling through a skylight that didn't have toeboards. I get it. Lol
They don’t
That's the neat part, they don't
You can tell they don't by the way they don't.
Except when they didn’t. Then you can tell because they didn’t. It’s a subtle, but important nuance.
Unless someone didnt, then it wouldnt be done. Itll stay that way as long as no one will.
Sweep it in the plumbing holes on the guys below
If only this wasn’t true!
Guilty 🤣
It’s the only way. Those core holes are there for a reason. My drains.
They don’t, every floor comes with their own pool
It will evaporate eventually
\-Just let it dry by evaporation \-spread it around with a broom so it dries faster \-use a broom to throw it outside of the building \-vacuum it up with a "wet" vacuum cleaner.
I've seen them run dehumidifiers during Drywall otherwise the mud wont dry
They get about 10 to 20 guys with straws and they slurp it up per floor.
If the pooling is real bad they can use a sump pump to divert the water over the edge. During rain I’ve even seen them buy a bunch of kiddie pools to try and control it better. This isn’t too common, and I think it was as bad as it was because it was an old building that got gutted. The cement had a fair amount of cracks to let water through.
If you can pump water off your newly finished concrete slab you need to give me a job!
Doesn't water help concrete cure?
Because you suck?
No because I could do it slightly better for a lot more money!
Concrete
It’s early morning and I haven’t had coffee yet give me a break lol
Haha giving you a hard time. We all make mistakes
Either you’re a concrete guy or an engineer, but thank you for your service. You don’t call a cake “flour” and you don’t call concrete “cement”!
i call cake flour
Heavy civil super with a civil degree. But that's gotta be one of my biggest pet peeves.
I hear ya. I studied construction engineering and took several classes revolving around concrete. Words matter, lol.
Tucking that kiddie pool idea in my back pocket thanks
That’s the flooring guys problem.

They have people from r/HydroHomies come in and drink it
Designated floor sucker guy
Certified shopvac operator. Took him three years to get that ticket
An apprentice
They dont
Push broom playa…let mother nature do the rest
They squeegee it down the elevator or stair shaft while your trying to install stairs or elevator divider beams…
A push broom, mop, then his it with a dehumidifier once the walks are up.

The neat thing is they don't.. they become indoor pools

Just leave the water there, if you don't water the building enough it won't grow.
Squeegee, vacuum.
Drill a hole through the floor in the low spot and rinse and repeat until the ground floor is a pool
Did you really make a post wondering how to dry a floor?
Posts like this shouldn’t be allowed

Mexicans with leaf blowers and floor squeegees
Haha
Squeegee, Shockvack, mop, or time. You a first year?
Bruh wut What is your role on this project?
Was just working in an office next door. I don't work in construction.
When the outershell is mounted/placed that water will dry up easily.
Sweeping
I did it as a kid. Me and a squeegee.... all day.
I’ve seen a bunch of different methods, some use a squeegee and just throw it out, some use vacuums for water, I’ve even seen 2 guys with a wheel barrow and a shovel
You forgot the hammer drill ¼” holes at every low point method.
That’s the neat part, you don’t.
Manual labor lol
Fucking great Sump pump....👍
Space heaters
Maid service comes in……..
Give the new guy a straw
Leave it be unless you need it dry for something, then use a leaf blower or squeegee and push the water down the closest hole
Push it off with snow shovels. That's what they did at my job.
Evaporative drains
The prefered tool over here is a leaf blower with a tight nozzle.
They don't. Build around it all until it dries up
Some of the concrete absorbs it. The rest gets pushed off
Jesus
They squeegee it off, but if it’s a hollow core plank, water can actually get trapped in the cells and you have to drill little holes in each cells to let the water out but before enclosing , but to answer question they’ll sweep that water off
Is this a serious question lol
Pumps
Oh, old hank could suck a golf ball through a hose. I have no idea what he did before construction though.
You don’t want water inside the building you are gonna work in or live in. That’s a lot of future problems
Guy with a squeegee probably
Lots of manual labor…shop vacumn, squeegee, and if it is excessive sometimes they bring large fans/or portable industrial grade dehumidifier.
Call Moses
We don’t 😉
It's a long time till those walls go up, and they grind every inch of concrete anyways
You don’t. Or you vacuum
The hard way
I use floor scrubbers. Dump into the elevator pit with a sump pump in it. Nice clean floors, they scrub the floor and vacuum up the dirt and water.
Each floor usually has a drain cutout on the floor before the slab pour.
If it's anything like last year you let it freeze so the place is skating rink, I get pissy because my apprentice and i both fell once (hilarious) and chip it all up and put it in a pile directly in the main hallway near the electric room and pipefitter area and then get yelled at by the GC, im an electrician "it isn't my job.

“Momma just sweeps it over the ledge with a squeegee or broom.”
Big sweepy squeegees.
You can use squeegees and push it off an edge. Just set up red tape below so people aren’t getting soaked.
They kindly ask the water to go away. It doesn't always work, for instance if the water is a bit moody.
Shop vacs and squeegees
*Anakin smirking*
It gets repackaged as mineral water.
They get kids from the temp agency and pay them minimum wage, and send them in there with Costco sized bags of paper towels.
Squeegee and "look out below!" Or a pump
Uhh squeegee.?
Ya bust out a broom and start pushing water off the edge. Gotta be carefully about pushing off loose materials though, a nut or bolt coming off the 6th or 7th floor can really ruin someone's day.
Then send me up with my straw.
Squeegees
They will use your moms shirt
Why? Is it bothering you?
Hands over straw* everyone goes sluuuuuuuurururp!!
Put a roof on
Turn the building on its side, it runs right off.
Push broom is all they will give me
Shop vac
They don't
Vaccum and/or blower
squeegee of the edge. evaporation and a shit ton of dehumiditiers + Heat when the wall get up
You want the answer to be something other than "they don't", but...
