I’m looking at having some concrete work done but I don’t know what would be a reasonable price. I’m looking at having a pad poured about 24ft x 30ft and either 4in or 6in thick. What do you guys think would be a decent price to pay for something like this?

Thanks.
 
Plan on $8-12 per square foot and you will be close. Your pad area is 720 sq. ft. So figure around $8k with all the work of prep, base, forms etc.

I just did 750 sq. ft. of pavers and it was $12k. Pavers cost about 50% more than just straight concrete.

Wow. The building I’m looking to put on it is only $10k I wasn’t aware it costs that much

It depends on the prices in your area and how much prep and form work is required. It could be half of that if everything works in your favor. Get some quotes.
 
$125.00 a cubic yard delivered 6 yd minimum. Seems to be average in these days. 24x30x.5=360/27=13.3cy 13.3x125= $1,666.67 this is without call outs for footers or Ramps.

That’s just the raw materials. Add in prep work, base, forms, etc and it is easily 3-4x that unless you do it yourself. If footers for the building are required, maybe a bit more.
 
I won’t be using footers or ramps. I know I’ll have to have dirt brought in, the site has quite the slope. I know I’ll have at least one guy come out this week for a quote

Yes this is a bare minimum for concrete I always try to add 10% waste factor as well. It’s all situational dependent you must of course account for your form work, aggregate, WWF or rebar, high chairs, plastic, expansion joints. I assumed he was doing the work himself. Hopefully, he has access for delivery of a standard truck and doesn’t need a pump truck.

I’ve thought about having it pumped. Not a lot of access for a truck to the site. But it is quite expensive.
 
Just helped do my neighbors driveway addition...11’x44’, $3k finished.
480 sq. ft, OP has 1.5x that...$4500 doing some of the work himself. The numbers are consistent.
 
If having dirt added because of slope, make sure of good compaction, other wise cracking will occur. Also, after fill and compacted, it is a good idea to wait for settling, even after compaction, some say up to a year for best results. It is best to pour onto virgin ground, can scrape off a layer, but be careful of adding fill to level.
 
I agree with Ddaddy in post #7
Get some estimates.
The cost of concrete and labor is different from area to area and contractor to contractor.
What we tell you could be way off from where you are.
Could be more or less.
You could multiply the length by width by thickness of the slab
That will give you the cubic footage then divide by 27 that will give you the cubic yards.
Then call the concrete company to check the cost per yard of concrete.That might give you a better idea.

The guy that does our concrete work compacts every 3” of fill. He does government work at the Air Force base and that is their requirement. You can literally drive the bobcat on the compacted sand and not leave tracks. He is very meticulous about every step of the job, and his 80 yr old Dad helps him, he has been in the business for over 60 years. They are a mule team for sure. They also insist on 12” block for every job, and laboring for them on jobs exemplifies the word “labor”.

Ahhh?
No footings and a slope.
Dude you need to talk to someone in your area that does concrete for a living. Not your neighbors slack jawed cousin.
Buildings that set on top of a concrete slab need structural support, ie footers.
You dont want to spend the money and end up with a piece of crap.
I have built several shop and storage buildings, do it right or dont do it.
 
A basic pad is a simple procedure. Kitty and I did the last bit I had added on before I put the shop up and our section is every bit as good and smooth as the contractor that did the first part. You can work wonders with a 2x4.
 
I worked on a concrete crew for a summer in '69. So I had a bit of experience.

My 1500 sq. ft. shop floor cost $2K when I had it done in '94.

Years later I wanted a parking pad and a driveway poured in front of my shop.

I borrowed some forms and set them up myself. My son was working construction so I got him and three buddies to do the pour and finish work for lunch and a case of beer. Two 30x30x4" pads for $800.00... was the only way I could afford to do it.

Manufacturing of the building does not require footers
 
It’s a prefabricated steel building. Uses 2.5”x2.5” 12ga steel as the framing
That sounds like alot of weight to sit on a slab without footings.
I am not familiar with that type of construction.
Good luck with your project
