There is no way your concrete is 11 feet deep. You may have a
wall that is 11 feet deep with a 4" or so slab on top, but the
concrete is not that thick. You need more information for anyone
to answer your question.

You would need to know:
Cost to excavate footing
cost in concrete and labor to pour footings
cost to form and pour walls
cost to fill and compact slab sub grade
cost to pour and finish slab
cost of reinforcing

and the cost to remove the first one

A 3,000 sq. ft. slab about 4" thick would be $9,000 at $3/sf. I
doubt you would get it much cheaper than that. The concrete alone
comes to about 37 yards @ $100/yard.

I'm very curious how much it cost my builder to pour a slab. The
reason I'm
curious is that they had to demolition it because they put it in
the wrong
spot. I have heard that concrete has gone through the roof, so I
don't
understand the carelessness.

The slab size has a 54'x58' footprint and has a depth of 11'. It
looks like
a wedge, so it starts off at about 3' at the front of the house
and
continues to the back of the house where it is 11'. Just a
ballpark estimate
will do.

Thank You,
