Just got a bid for a 32x28 6 inch pad $6000

I have removed a lot of concrete and the only place you find wire mesh is on the bottom and rusted. 95% rebar here.

I've installed a lot of concrete and we used a lot of wire matts. We used chairs to support the wire in the pour but we still had guys pulling wire as the pour was dumped. We did a lot of the Walmart stores as they were coming into the state. Ten and twelve thousand square foot pours were common.

When we use it, I'm always pulling it up, our lazy foreigners. Not so much.

30 cubic yards, figure you want at least 10% overage so 33 Cubic yards. Local price is 125 a yard so about $4,200 in Concrete. Not sure if you were planning on doing it yourself or having it done, no idea how concrete guys price out their work.

I had fiber in my floor.The floor cost me about $14,000,if I did it for somebody else, it would of cost them around $20,000.
Strait 4000 pound concrete cost me around $110 to $125 per yard with delivery charges.

I just got a quote awhile back for a building I have with 4”, 4500# concrete. Came back at about $4.50 a sq ft. That is concrete and labor.

I have no employees anymore,I do hire subs at $36 per hour ,and sub myself out at $36 to $52 an hour.I do carry Workers comp on my subs.That cost about $3.60 an hour for each hour they work.I am a very small company that has been in business for about 21 years.I have never even had a business card, nor sign on my truck.I have been paid in full for every job I ever did, and have never had a signed contract.

I do a 1400 sqft floor on Monday that is 5 inches of 4000 psi concrete with 10 gauge wire for $4.25 a sq ft

I just checked on a slab yesterday,160.00 a yard delivered, and a two week wait. Average cost here to have it done with rebar is going to run at least 6.00 a square foot. If I could get the slab done for 3-4.00 I'd build a much larger pole barn.

Al,must be NY prices .I can’t find it much cheaper around here .

Easily 28K here, and no one would pour only 4" thick. Concrete is like gold in this neck of the woods

We would not pour it 4" thick. If you figured 6" average should cover you.
should have some rebar if a steel building.
Around here you could probably get it in the $17,500 ballpark.

It looks like the price varies a lot depending on where. I guess I need to get some quotes from around here after what some have said I may go 6 inches.

Get a couple quotes if you can. Go with 6” and 10ga. wire. Get references if you don’t know the contractor. Look at some of their work!

I'd talk to a local engineer. Given your climate, and depending on your soils, you may be ok with four inches.But I would absolutely include reinforcement with rebar and/or mesh

Drainage and compaction are as important as what you put in the concrete. A good heavy base will make all the difference.

I paid $12/sq ft last summer. Nice stamped colored concrete and they had to buggy it in

What are you parking on it, use????? Your floor is only as good as your base.

Guys that did mine use 2+6 forms and you get 6 inches of concrete. The grade dense grade to the specs THEN set the forms on top of that . Most set forms then fill with rock then pour. Once the forms are set no more rock put in
