House slab cost - 247m2

[col5555]

at a guess, somewhere around the $18,000 mark for the job, a lot can depend on how much the concreters charge, you need to shop around, some deal only in house slabs and can be reasonably priced
reo, bar chairs, trench mesh etc shop around, prices can vary widely, you may find yourself easily saving a few hundred $$, garden / building supplies (here at least) usually carry reo, trench mesh etc

On them money my quote is $18000.00 exactly. The puzzling thing is I spoke to a guy around the corner from me who had his slab poured around 3 months ago and his slab was 300m2 and he paid $13000.00. Same class site with thickenings and footing detail. The contractor did not use a pump but this is costs around $1000.00 ??. Looks like I have some more homework to do.

We had a shed slab done. It was 7.5 x 12, with thickened edge all round and cost a tad over $75/m2. That included 4 rather deep post footings. It was a level site, pretty easy access, and the concreters did everthing.

That works out to be $43 a square meter. Sounds like someone is telling porkies. Thats pretty much cost,if that, and a good way to go broke. Slabs aren't fun to do and can be tricky, not to mention hard work. There is only one chance to get it right. Any one can concrete but not everyone can get themselves out of the &^@# if things start to go pear shape.

Looks like the prices vary slightly in different places in Oz. On average, $80-$85 seems the norm. Supply and demand plays a big factor by the looks of it.

Uhmm, correct me if I'm wrong here Ivan, but I think Ivan's slab is for a shed with steel frame and cladding, therefore termite protection would not be needed.

As long as he doesnt line it with plaster, or use any wooden cupboards around the penerations and also uses some sort of wiring in the walls that termites wont chew through, i guess he maybe alright.
If its just a shed

I have costed everything up and I get $12173.78 in materials only.
45m3 @ $187.00 m3 inc gst m3 = $8415.00
26 sheets trench mesh @ $32.67inc ea = $693.42
17 sheets SL72 mesh @$80.08inc ea = $1361.36
chairs 100 qty @ $38.50
Boom pump 3 hrs $1137.50
Mini Excavator 4 hrs $350.00
70 qty N12 ties @ $2.50ea $175.00
These prices are retail and I am sure a regular costomer would get them cheaper.

Would 3 hours be enough for a boom pump to pour 36.7m3
They normally pour footings one day then thickners and slab the next.

So would labour normally be $5826.22??

What about formwork, and vapor barrier ? Also levelling of site by bobcat and placing sand. Hire/wear & tear on formwork and helicopter. Maybe they're making a lot of money, maybe they're not.

I never happy unless I have a VIBRATOR.

Settles the Concrete down nice;
and easier to get to flow rather that TOO much Shovel work.


$100.oo per day PLUS Transport

up here
Transport $80.00
BOTH WAYS

Formwork!

If it is not right, then the whole thing is kaput.

A friend did his own, and when the mix was poured, it collapsed.

Pumps usually charge min 4hrs plus travel. Plus around $4-$5.00 per cubic.
"They normally pour footings one day then thickners and slab the next"
Thats two days so far without allowances for formwork, slab prep and ground works.
Seems to be at least 4 days work at around $350 per man with all legals included. (w/c, super etc...). Say three men per day. $4200.00 so far. Fuel, formwork, all equipment for the right job (trowelling machine, laser level, nails, pegs etc...
Profits are getting smaller. I reckon they are right on the money with that quote.

Hi All,
I recieved a quote the other day for my house pad and I was a bit shocked as my estimation was no where near what the quote come in at and I was generous in my allowances.
What do you think the following job would be worth.

247m2 slab area
45m3 of concrete @$209.00 m3 = $9405.00 (over the phone price at retail) they said can do better as so much concrete
79 metres of external footings 300x350 to be dug
145 metres of thickinings 300x300 to be dug
trench mesh
N12 ties
SL62 mesh
WPM
chair bars

I have been told that this amount of concrete will require pumping and the footings/thickners will be machine dug.
What would the reo/mesh/wpm/chair bars/ties be worth appx Ok! and average labour cost.

Where abouts in Perth are you? I'm in Carramar and I need quotes to do a concrete pour on my limestone block extension................. also around the side of the house ............ as well as a pad leading up to a new garage. The patio needs backfilling and compacting too.

In total it will be roughly 300m2 give or take.................. any idea cost-wise ........... and can you recommend anyone in Perth?

[col5555]

Cant recommend anyone at the moment,still sorting it all out sorry !.
Can let you know once I have sorted it all out.

an example, a person off the street will be charged about $170 - $180 per m3 for concrete, a high volume account customer can get the same concrete for $100 per m3, that is a $3k saving, SL72 reo, $55 a sheet etc, so the cost of materials could well be down to the $7k mark, as for formwork, it is not as if the contractors buy all new formwork for each and every job... as for labour, quite common for that to be about the same price as the cost of materials. So if the quote is $18k, they are working aon about $9k for materials, not bad for a couple of days of work for a crew of 5 or 6 (do remember though, house slabs are a big job to do right, not a job for the home handyman to tackle, thats for sure)

Concrete pump - slab of Jim Bean & Cola + $100
Mini excavator - slab of Jim Bean & Cola + bottle of chivas regal

of course, it helps to get these rates if they are mates
