    Default Estimate cost of garage slab please?

    Hi guys,

    I was just wondering if anybody know's what a fair price for a concrete slab in Sydney would be right now.

    I am getting a metal kit garage built soon and the slab is 6.0m x 12.0m.
    It is 100mm slab with a 200mm deep beam across the 12.0m front edge.

    I would appreciate if anybody could give me ideas on what they think is a fair price to prepare and lay the slab, mesh and everything included. The site is almost flat already.

    I have been given a price by someone for $8500 cash and he says that only really covers costs and they are putting very little profit into that price.


    Thanks

    Adrian

    Hi aabb,

    Thanks for the reference, but how does that help me?
    I'm not looking to do it myself as I just don't have the time.

    Thanks

    Not Sydney but my shed is the same size and cost me $40000.00, that was everything, base, mesh, chairs, concrete 100mm and 150mm in places deep and labour.
    That was about two years ago.
    $8.5 sounds a bit steep.

    Thats one helluva slab!!!!:eek:

    juliussee I had a slab for a shed done about the same size 12 months ago. Total $7300. I think the rate was $65 per sq M and $68 per ln M for piers with a 200mm thickened edge. (+GST of course)

    Rough guide, work out how much concrete you need, get the price per cubic meter double it and add $90 per sheet of reo

    Roughly 8.5 meters of 20mpa concrete at about $150m3 (melbourne) so about $1200 for concrete

    Reo, f72 around $90 per sheet x5
    bag of 50/65 bar chairs about $20

    So a rough price would be somewhere around $3,500 - $4,000 I would guess.

    Or you could do it yourself for about $2,000 (I did my 6m x 7m slab, ranged from 150mm - 300mm thick for under $800 - got the 25mpa concrete cheap

    Thanks for the replies guys.

    It seems that prices can vary greatly.
    Looks like I'll just have to get a few quotes and take it from there.

    Thanks

    We just did 80m2 for a cricket net and I charged the client $5K as there was a bit of muddling around... muddling...get it...Oh brother .

    $8500 cash is a very expensive but I haven't seen the site and some jobs can run to that much.

    The cricket net was easy because the guy who boxed out the slab area in the Bobcat was a genius!

    Cheers

    Best way is if possible . Ask around as some of your mates will know a granno . Ask for the cash price with you supplying the labor . Put on a BBQ and Crownies for about 10 mates . 1 granno and your mates will do it easy . $8000 is very rich though . Plus check his work . I've seen some shockers lately .

    We had one done here in Canada for about $3000 but I guess shipping would be expensive

    wow . I built my own shed 12m x 8m for that price ( $8,000) complete , roof ( G.I. ) , trusses , slab , walls etc . mind you that was 12 years ago . I did it all myself though .
    As stated earlier $4,000 sounds right for materials but I reckon labour would be on top of that . Just my opinion .

    Adrian,
    Afew months ago 3-4 (approx) I had a slab 5 x 6 mtrs x 200mm thick, 82? reo (3 sheets) was used, a level site but needed a bit of fill (old pool) cost was $5400. So adding the extra for yours seems about right give or take a few buck's!....

    5 x 6 x 0.2 = 6m3

    6 x 12 x 0.1 = 7.2m3

    $8,500.00 cash is very high....(just trying to give a general tip here)
