Bricks, Masonry, Asphalt and Concrete - Single pour

I've done horizontal pours and vertical pours, but I've got a customer who wants a small project done, and I want to make best use of a delivery. It is a 3" slab measuring 8' x 17' outside a basement entrance. However on one end is a small 4' high sloped run off area of dirt. The basement is a monolithic pour. I want to take off that monolith with a 9" thick wall, extending out 8' and 4' high to prevent run off from getting on his new concrete.
Now, the question, can I form it all up and make the wall and horizontal pour at one time? I don't have a problem doing it, but I just wondered if continuous pours are ever made like that? Or should I suck it up and do the wall and floor separately? If so, I will have to hand mix it, due to the minimum delivery from a truck. If I can do both at one time, I can call in a truck.

It would be better to do them seperately.

Normally I am not a "why" person, just ask my wife. But it would help to know why.

If I'm reading your question correctly, the wall and slab would be poured at the same time in basically an "L" shape. At the bend in the "L", the concrete will crack the length of the wall (re-entrant corner).
If the wall was poured first, expansion joint material would be placed against the wall before pouring the slab. This would allow the slab to move up and down with frost heave or temperature fluctuations with no cracking along the wall. Also, the size and weight of the wall would necessitate a proper footing under it.
Edit: Okay, I see you're in Georgia. Disregard the frost heave thing. The other info about cracking and weight is still valid.

Makes sense on the difference in the lift of the two portions. I guess I will have to hand mix the stuff. Crud! Wouldn't mind the wall cracking from the horizontal slab, as long as the crack went vertical. I am trying not to have a lateral crack for water to seep through. I guess I should pour the footing and wall first, then the slab.

Ahhh chandler...yer not going to be doing the mixing yourself are ya? Isn't that what helpers are for?

Well, really my helpers will be loading it into a mixer. I will watch it turn and count the revolutions and drink coffee. I believe that's how it goes.:p

I KNEW it! You may have to place the order..but someone else will prob be responsible for pickup/loading or delivery.

I know what really bothered you was just the time issue.

Like a piece of glass, huh?..............................

Clear as mud....

chandler are you a contrator??

Yes, but in remodeling, repair and restoration. I don't normally do new construction, which this would fall under.
