Garage Foundation Cost

Good luck!

This floor is bulletproof. I have a 7000lb lathe and a 5000lb mill on one end and it hasn't budged or cracked. I really had a tough time deciding to spend the extra money making the floor that 1" thicker, using rebar instead of mesh, ordering the 4000# mix and giving them the extra few bucks for the fiber reinforcement. In the end I would have been an idiot not to have. It was worth every penny I spent.

Don't waste time with the wire mesh. If it is light enough to handle without a crane it is nearly worthless. Rebar can be blocked up and doesn't end up sinking to the bottom or floating like the mesh will. The rebar cost me about $50 LESS than mesh for my shop. You have to buy complete rolls of mesh and I would have wasted about a half roll.

Due to everything going up in the last year, you might add about 25% to that figure. Count on $4000 and you'll have money left over if you do it right.

I just built a 25 x 30 enclosed shop with 30 x 50 open (total area was 30' x 75'). The concrete for the 25 x 30 and 4 more footings cost me $4700 to complete.

I would think you could do it for 3-$4,000.

On the concrete, just take the dimensions of your form(s), I'll use the slab for example, say 30'-0" x 40'-0" = 1200 sq ft. x thickness of slab = 6" divide 6" into 12" ( 12" = 1 foot ) you get 0.5 as a decimal to multiply so 1200 x 0.5 = 600 cu. ft. divide by 27 ( 27 cu. ft. in one cu. yd.) = 22.2 cubic yards of concrete x $90.00/cu. yd like it is around here = $1998.00 not including reinforcing like 6"x6" woven wire mesh, or rebar, and this does not include forming, placing, finishing, stripping of forms. Also with this quantity I'd order 23cu. yds., hate to be short, so a little extra is not included usually 1/2 to 1 yard over will suffice, been there done that, just the cost of doing business

If you do plan some sort of knee wall, take the dimensions and multiply to get the cubic footage, of say a footing and the wall, then do the above math to get the cubic yardage, if the wall is 12" thick, then multiply by 1 to get the cubic foot volumn, less then 1 foot or 12" take that thickness dimension and divide by 12 to get the decimal equivalent of the thickness to plug in for the cubic foot volume. Most likely you will contract it out, and if so, at least you can get an idea of material cost up front, then ask the contractor how many days to do the job, you can then plug in his estimated labor cost and arrive at an accurate number to compare with others, also helps you from getting gouged, some of these guys will throw a high number at people just to see if they will bite.
