re: Cost of pouring concrete for patio

Why would he need a 6" slab for a patio?
Jesus!

Don't forget 1 mat of #4 rebar on 12" centers suspended approximately 1/2 way into the slab and either trowel in or saw cut a contraction joint every 10 feet about 3/4" to 1" deep to prevent cracking.

Right now, I think concrete is about $116 a cubic yard.
$116/yd your getting screwed big time

ACI recommends 13' so 12.5' should be good enough.

The house is built on a 4" slab but hey lets add a 6" thick patio with no load to justify it.

I wouldn't pour anything less than 6" if you want it to last. If you want to slap some #3's or #4's in there it couldn't hurt. Some wwm T and B would probably suffice. Anything less than 6" thick you're looking at the slab moving or cracking especially in south LA

Houses also have footings and grade beams dumbarse...

I know. I would venture to say I have built more of them than you.
It would be cheaper and better to pour a shallow footing on the patio than to pour a 6" slab.

Yeah but we put em every 10' unless it's an odd sized slab, but you are correct 12.5' should be plenty.

I don't associate with mud divers but if a client asks me to do some paving it's gonna have a shovel (skirt, for the ladies) beam.
Also, I don't see how a deeper slab helps. Cracking is a tensile problem and only reinforcing will solve it.

I've gotten in the habit of using 12.5' because it works well for construction and expansion joints using increments of 25'. Still, it just depends on the situation.

Don't forget to dowel it into the existing slab your pouring next to.

Correct and spend that money on a shallow footing to help prevent washout instead of wasting it on adding 2" of unneeded concrete.
Not to mention that a footing will do more to prevent the settling he mentions than an extra 2" will do.

I don't even know why you bother speaking to these peasants.

Yeah we do mostly large industrial stuff and it's never a square or rectangle so we tend to cut em closer just to be on the safe side.

I would agree with that. A 6" grade beam along the perimeter combined with a 4" slab would probably work just fine. Just be prepared to reinforce the GB's with at least 2ea #4's all the way around.
FWIW I'm an industrial guy. Don't have much experience with smaller at home projects. I do agree with the guy who mentioned the Home Depot employees tho. As long as you can supervise and know what you're doing.

Make sure you have expansion joints in the appropriate places.
I think you know what you're talking about but in no way does he need an expansion joint

600sqft at 4" with a 8" deep by 6" wide will get you to need about 9 cuyd's which roughly will cost $900 give or take.
figure $100 for formwork
figure $250 for rebar
figure $700 for labor
figure $160 for tax
looks like $2100 plus or minus a couple hundred
this is assuming you set set the forms and rebar
if not add another $300
also, put a little bit of expansion pad if butting up to other existing concrete.
and have the place and finish guys sawcut a couple of control joints every 8x12 (or any variation but not to exceed 13' an any way) area to control cracking
