House slab cost - 247m2

[col5555]

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.

somewhere between 40k and 60k for all that i'd guess. rule of thumb about $300 per mt2 with footing trenches pumped.

[sol381]

That seems a bit rich. I was quoted recently between $100- $120 m2. even at that price they are making good money. If you can get someone under $100 you`re doing well.
You seem to have a massive amount of thickening beams for a slab that isnt huge. It is a P site or are you just over engineering.

I've just had my Slab put down.....[Green Dreamed it].... Sorry; back on track

Slab:
It was 100mm - 125mm Thick;
12M x 12 M..........144M^2
MAIN Building:
9M x 12M including the Trenches were Visqueened

Awning:
12M x 3M......No Visqueen

There was a total of 216 metres of Footing which was poured in-situ with the slab.

Trenches were every 3 Metres......because of Highly Reactive clay...here it is either FLOOD or Drought....Grrrrrr!!!

Included were:
F72 Reo
Trench Reo
Chairs etc, etc, etc
also Drainage for Shower, Laundry tubs, Floor Waste and toilet
40mm Conduit for POWER

COST - about $10,000 - $12,000,
I don't know the final Cost,
as They are trying to hit me for Double a few items.

Double GST on the Garage Kit
Double Cost for Extra Gravel and BobCat
Exorbanate charge for the mounting of the Electric Roller Door Motors...10-15 Minute Job,
AND
I have done it myself elsewhere, ALONE
and a couple of other 'EXTRA Costs'

No!
Not yet passed over any $$$$,
Will,
but will hold some back

[Ivan in Oz]

So that works at about $80.oo to $85.oo M^2

Should there be any difference between a House Slab and a Garage Slab?

I think not

One local built his Garage to live in while he builds his House AND Remains on Site. All above board

It is a class S site,they found clay at 1000mm depth, I am filling a further 300mm.
The engineers specify 1st thickner 4.0m from external wall then at 5.0m centres and under internal walls if more than 1.0m from a thickner.
The house pad is 14m wide and 25m long.

[Dirty Doogie]

$85 a mtr 2 ??? Unbelievable !! THE $300 figure I gave was from a builders quote guide and includes excavation, pumping, reo, underslab treatment and approvals/certifcation. I dropped the final figure to about 200 mt2 becuase companies will do deals.


So how much was your quote? Day rate for Leading hand concretor around here is $800 - a laborer - $400.

[Ivan in Oz]

DD,
No Pump;
The concrete Truck could drive right around the Slab.

No real 'Treatment' either
Just had the Pad levelled 3 Months earlier
and ordered a few STORMS to wet the Pad down

[Dirty Doogie]

Hi Ivan - yeh I noticed from your pics access would have been eesy peesy - but still - I think you got a good deal.

Cheers

what sort of termite treatment did you use for your penetrations?

[Ivan in Oz]

No treatment required that I know of,
though he might have done it
Just that I don't know about it, YET!

Concrete Slab,
Galvanized Steel frame,
Colourbond Walls and Roof.

I'm not an Owner Builder.

The Timber comes later when I start to Play

If you are getting a builder then he might of had it done,
if not you might be in trouble there.
find out ASAP

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.

[peter_sm]

Cost me $100 per sq/m (90 sq/m) and that was with contracter doing all digging, me doing formwork and mesh along with brother-in-law who is a builders labourer. I had to get a pump, as the truck could only do from front. BIL did screeding and floating of slab.

I would have expected I saved $20 per sq/m, so if I was quoted $120 I would find it reasonable, now I know what is involved.

This was for a slab very similar to what you described.

I would hope they would do better, $160 - $180 is what I would expect to pay (retail)

79 metres of external footings 300x350 to be dug
145 metres of thickinings 300x300 to be dug
trench mesh

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
