Concrete slab cost

[Scotty370]

Just another aside: I cannot image owning a garage/shop/storage, combo, without a concrete floor that I can roll an Engine lift, use a creeper, or stow a back-hoe, box-blade, bucket on a wheeled dollies, even a 'wheeled' welder. I know that everyone's budget is different, but I think that after the Show tickets, the dinner and the wine, that the "happy ending", is the concrete floor.......... ~Scotty

I have a simple plan that I am going to modify slightly. The original plan calls for a wooden floor on skids, however, I am going to pour the slab then put in a five course run of block (40") then build the stud walls up from that. I am doing this to increade the ceiling height to accomodate putting the tractor inside for maint.

Like most folks, I don't want to break the bank, but want it to suit my needs.

Just poured my slab in December. 50X75 for the building and 25X75 paving for the lean to. 30" perimeter beams with interior beams at 25' centers 30" deep. All concrete is 4000psi with #4 rebar on 16" centers. Slab and paving at 5" plus. Stirrups at 30" for the beams. I bought all the materials and hired out the labor from some customers of mine. The total cost was $3.05/sf. The best quote I had for this project turn key was $6.00/sf. Concrete was 68/cy and the pump truck ran an extra $500. I used 800cy of select fill that I borrowed from my future pond using my 5083 and a 3cy scraper. I probably spent $1500 on fuel and excavator rental for the dirt portion. Had I hired everything out it would have cost around 40k, but final receipts are just a bit over 20k. The building has 16' walls and 2:12 pitch with 3-12x12 roll ups and 2-10x12 rollups. Finished it off with 4-walk throughs and windows. Total cost for building with slab and pad is $65,000. Then there is the water well and 1000lf of underground primary and 400amp service. Need to install the third mid-valve so I can hook up the hydraulic post hole digger and start fencing.

Man Aggie- I feel like I'm building a 'Refrigerator Box' by your standards! (But at least it's a 'MayTag')!:laughing: ~Scotty

Let me add the suggestion to not scrimp on what you want.
Visualize what your ultimate goal is and go for it. The $100 saved now becomes $400 to correct later and entails years of wishing it was done more to desires from the get-go.
This is a great thread with some wise advice.

Whether you are building refrigerator box or distribution center do it right. Concrete can not be fixed with a welder or duct tape. And remember, your foundation is only as good as the soil that supports it. If you have high PI clay, then use a minimum of 2 feet of select fill compacted correctly with the right moisture. Don't skimp on reber either. Wire mesh is for sidewalks, not foundations. Use 1/2" on 16" centers. Conctete slump is also very important. Make sure it is a 4 or 5 since watered down concrete loses a lot of strength.
I built bridges for six years and played with a lot of mud. Feel free to ask any questions.

Aggie- I hope you took my comment in the 'humorous' vein, that it was intended! I was trying to say that a 28x40, was a postage stamp as opposed to your endeavor. That said, I will take you up on your offer of advise. First, no-way I can handle a 2' sub-base, but I would like your 'take' on the use of foam over the top of compacted (6-8") crusher. KennyD took that approach, and I kind of like it! If you search out his posts, he has a great photo portfolio......~Scotty

Last year i had an engineered slab, 40 x 60, poured. 4 loads of material for the pad, 4 ft perimeter beams, #5 rebar in the beams and #3 in a 1'x1' grid. 100 yards of concrete.

$24k

Black land is great for growing crops, not so good for concrete.
