24x30 concrete prices

[Svrdram]

Hey guys, I'm trying to roughly figure out what its going to cost me in material on my future garage build. I'm in the detroit metro area, garage is going to be 24x30 4in slab "3000psi" with a foundation 12" wide by 42" deep. Any info would be greatly appreciated!

Im in the Chicago area and a good price would be right around 15k. As long as u dont have get a pump truck can get machine into to dig footing or anything crazy. Just get at least three estimates and im sure they will be all over the place.

A good quick gauge to use is $250 average cost per yard for concrete and labor combined and you should be reasonably close. The cost could be a little more or less. This does not include site work.
24x30x3"=6.67 yds 7 yds @ $250 yd =$1750.
24x30x6"=13.33 yds 13.5 yds @ $250 yd = $3375.

Mine was almost identical, but 24x40:

Concrete work was $7400 start to finish, including digging, rebar, etc. (in Idaho)

i cakulated 24 yard of concrete. 14 in stem wall and 9 in slab that 24 yards, concrete around here running about 100 dollars a yard $2400 for just concrete. you never mention the footer size. that just concrete, no labor, no rebar.

 

[brownbagg]

that 24 x 40. i dont like the layout. too much wasted space. i would of left the plumbing out, put the small door on the side. have one big over head door. that way you get two cars in there. with the bathroom, not enough room to work on one car

Mine is 24x40 and I love it!

I'm out of space though and I'm building another shop to go along with it. I didn't build this one. It was here from the previous owner.

It is not your shop, so your opinion is of no value to me.

Got a price today of $8600. Roughly $2200 in the foundation, $2500 in the slab, $800 in block work and $2500 for 2 trains of gravel, site work and final grade around the shop and yard. Of course some prices weren't broken completely down such as renting 2 buggies, extra laborers to drive then ect.

The foundation is including the footings. Its a straight pour thats 42 inches deep 12 inches wide with one corse of block.

So went to the building department tuesday morning at made a revision on my plans. Its now going to be 24x32 with a 24x20 pad in the front and 8x24 pad in the back. Total price including site work, 120yds of sand, concrete and block work, digging a trench so I can run my gas, water, electric and final grading $10,000.

 

[joes169]

I think that's a relatively fair price, and here in SE Wisconsin, actually on the cheap side for the amount of work you're getting done.

 

[Svrdram]

Yea, I was giving a number of a guy to call from a good friend for a second estimate. He told me the guy Nick works for Poisen I think its spelt, anyways the company does alot of the dot bridge building here in michigan so he knows his ****. So u call him up and start telling him what I want done and he goes "I think I've been out to this site, are you Vince's neighbor?" Turns out he works with the original guy who qouted me. Was really nice and broke down all the prices, said whats killing the job is that they have to buggy all the concrete 300ft and its over 30yrs of concrete.

 

[joes169]

Sounds like "Nick" may be doing the work on the side, so he should be able to do it quite a bit cheaper than legitimate contractor. Make sure you get a written contract that spells everything out, and don't pay him in cash...........

 

[Svrdram]

Both the guys doing actually concrete work I just found out do road construction. And they have a full crew working for them during the day, fully licenced and insured contractors with a day job. "Nick's" partner is a neighbor that lives 2 blocks away. Trying to support the local guys.

 

[Svrdram]

Let me ask you guys a question, I just finished up a "manifold" consisting of 2 pieces of 2" and 2 pieces of 1 1/2" grey sch40 pipe to run all my electric (2") water (1 1/2") cable, phone and ethernet (1 1/2") and gas is the finial 2". I was offered the use of the mini excavator ,that the guys brought over for the footings, to dig my trench and run my pipe. So I went and bought all my pipe but I'm wondering if there is anything wrong with running the yellow PE gas line in the pipe?

 

[Svrdram]

So far so good

I just poured my own last month for my garage addition in central illinois. I added a 26x30 4" thick with a 12"wide x 36" footing. I used 10 ton of rock as a base and about $350 in rebar. All together I spent $2300 in material and did it all myself with some friends and it turned out great. Lots of work but well worth it. On top of that, I had to get a mini-ex to dig out the footing for half a day rental. I know labor is expensive on concrete jobs and you will also add up when paying for excavation work. But if you can do anywork yourself it will save you $. Good luck in what you do and I'm sure you'll be happy with the end result.

 

[Svrdram]

Yea, I'm going to be doing all the building and electric but I'm currently working either 6 or 7 days a week with 10 or 14hr days. At that rate it would take me weeks if not months to get the concrete finished. I think they said I'm going to be close to 30yds with my sidewalk and locally concrete (6 bag mix) is $110 delivered over 6yds. Plus 115yds of fill sand which is $24 a yard delivered. So thats $6060 not including equipment rental, mesh, rod and block. After breaking everything down I feel comfortable with what I'm paying, don't take me wrong I'd much rather only pay half that but thats not going to happen in my case.

I had a 32x40 poured two months ago and it ran $8900 with the 42" footer, 3 rows of block, and a 5 inch slab. I would say your price is real close.

How much site work was involved? We did have a talk after my neighbor use her drive to allow access to my back yard for equipment and cement trucks to save us time. He said that should knock about $800 on the price to save on renting a buddy and time.

I have access on my other side of my property but its where all my drains run to.

 

[Svrdram]

So I got a call from my concrete guys this morning said that they would be by this afternoon to pour the footings. Said that the trucks are scheduled to be there at 4:30, so I get out of work at quarter to 5 and I'm home at 5. Walk around back to find to cement trucks in my back yard.

 

[joes169]

Are you sure this isn't a side job for these guys? I can't figure out any other reason why a contractor would pour so late in the day.

And btw, where is the vapor barrier, and what's with the humped up sand in the slab?

 

[Svrdram]

Ok, I'll break it down. They both have full time jobs and are licenced contractors with a full time business (2 crews) but since they both live in the area they personally took on my job (we have a close knit neighborhood). Today they were just pouring the footings, going to come back and do the block work then regrade the sand and compact it. Then I need to get a another inspection before pouring the slab. It will have 2 layers of 40 mil vapor barrier and 2 layers of road mesh (the thick stuff) as well as a carved out area where the hoist is going (6" thick).

 

[Svrdram]

Came over early and started the block work. They own all the equipment pictured but had to rent a mini excavator since he blew out the pump in his not to mention his 10yd dump and backhoe he brought over to do the prep. They are not just "on the side" guys.

Any updates?

Took me a while to figure out why this guy would even post this considering you said that you were only pouring the footings.
Truthfully, still haven't figured it out.

I just had a 24'4"x 30'4" slab poured in Texas, yesterday with footers 10" wide by 18"deep. Labor, materials, everything, $3,750
