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
Building a skyscraper? Why do you need the slab 11 feet deep? Hoover dam
is not much thicker.
Careless errors happen no matter the cost. Could be a $5 item or a Hubble
telescope. I know one guy that order things in feet using the ' symbol when
he meant inches and the " symbol. Boy, did he feel stupid afterwards.
Material has to be around $30,000 +++ if it was solid concrete. I can't
imagine the cost of taking it out and hauling it away, unless it was a
matter of moving a short distance and using hte old material as filler for
Dear OP (Zzyzx)_
Something thing defintely wrong with your description of the situation
or the situation itself
54' x 58' x 3' tapered to 11' is approx 800 yds of concrete (3.3
Think would be ~90 trucks! I don't think so.
A massive multi-lane concrete overpass can be on the order of 1500 yds
The structural engineering test lab where I worked had a floor 50' x
80' x 2' thick & a reaction wall 80' x 21' x 3' thick
Even at only $100 yd monolithe you're talking would be about ~$80k just
for the mud.
Perhaps the real situation is end wall & side walls then back filled &
covered with a slab; a much more cost effective way to generate that
Assuming 6" slab & walls the same configuation would be about 80 yds,
much more resaonable
I have never seen residential detail as you describe
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.
