anyone know a rough current price for concrete per m3 ?

Starts at around $160 for a concreter, you wont find much cheaper, unless they buy a lot more but im not sure how much more it would drop by. Some pay $180 or $190

I just got a 6x6 slab put in for about $2600 for my shed

Depends on the strength you need,mix design, the distance from the batch plant and volume.
Minimum cartage rate of 3m.
Mini mix dearer.
Ring around for best price,everyone is keen atm.

Yeah 6m x 6m

ok so lets say average $175 per m3.

ok 18 x 10 ummm 5 inch? I wont be driving any heavy vehicles.

so where was I? oh yeah 18 x 10 x 0.127 = 22.86m3 = $4k just for concrete

x 2 the price for reo, plastic and labor only the concreting itself. My team and I will be doing the digging, leveling, compacting, plastic, foam separators etc...

yeah 8k is doable. My half bro does sheds and has been doing for well over 20 year, he actually built my shed. Got some friends of his who do concreting for a living which will join the project
at a mates rate dam I feel cheap. My half bros idea I swear!

Always a good idea to get the subgrade checked by the floorlayer before reo goes down,nothing worse than lack of cover.
Plenty of excellent floorlayers about will work for collin ash.
At 180m/2 you will need a few men,may need to factor in a concrete pump depending how solid the ground is.

going rate around albury for crete about $180m3 place and finnish $22-$35 per m2 no earth works. its a good time of the year to get helpers in as theres not much on, concrete pump costs bout $130 an hour minimum 3 hrs $5m3 wear charge and $3 a klm.

hmmm great to be in the know

Got mine done nearly three years ago but keeping in mind i lived in north qld and everything is more expensive
12 x 18 bonded beam slab reinforced in roller door bays with 2m cubic hoist reinforcing beam = 30odd metres of concrete, cost $185 a metre plus milage surcharge, helicopter finished, 6 workers and bobcat hired $24k job in 8hours kinda makes you feel sick when you look at it that way
never the less love the concrete floor good jobs cost money
probably should add that it was increased hardness concrete and had slower cure additive put in to reduce cracking

f**king hell! that expensive as hell

We have man power with several people, which only 1 or 2 are being hired at a mates rate anyway. My half bro has a vibrating roller, excavator, normal vibrator plate.

He also can get all the GST back for me as heel can put it under his business. So we estimated 8.5k with extra 500-1000 buks in case whatever and this was estimated on a 20 x 15 slab
so when i measured it and got 18 x 10, realistically we got 7-8k but I have 9-9.5k anyway.

I wont be doing it in 8 hrs. the preparation will be a week or 2.

Amazing how it pays to get quotes. 5 years ago now, building house and shed at the same time, shed is 12 x 18, house slab similar area, quotes varied from 20k to over 40k. I got both and another for water tanks with uprated concrete for about 24 all done.

lol you can add another 10-14k on that price for other quotes. Gee I love north QLD.....

yeah quotes are varied but the top end dudes all seem to hang around the same usually bout $65 m2 all up but this can vary as the site and soil changes and who the quote is for, double it if its for a teacher or triple for a university lecturer!

I have been recommended I should only need 3-4". yeah right, so i talked to my half bro who was and engineer for over 30 years and did sheds on the side and still does.

He recommended 5" he has 6" in his 2 sheds which has a massive fork and 10 ton truck and few 10 ton lathes and he even used to have a 35 ton lathe.

No problems at all. its all in the base preparation. hell I could go 6" for extra 500 buks.

I may have a hoist one day? possibly a small fork? for what I don't know. Yeah the shed will only be for cars. I do plan for a gantry system but that's nothing to do with the slab.

Your brother is right, subgrade is the key. Its almost like body work, the prep really makes the finished product. 100mm is not out of the question for a light weight slab.

It surprises me that no-one has mentioned the importance of STEEL in all of this. Without reo., concrete is not much good - no matter how thick!

and an edge beam with steel as well

9-10 grand even with mates rates is cheap. I paid 26 grand 26 years ago doing my house slab which is 210 m2. Granted its near Canberra and Pub rates apply even if your not one of them.

Your budget is missing BEER all concreters drink their weight in beer immediately the job is screed. I believe the rate increases for mate rates. M

as mentioned steel is only for crack control in a ground slab, however i did a slab afew years back that was 350mm thick top and bottom sl101 mesh for a forge around here that supports 40 tonne manipulator that picks up red hot 15 tonne billets and on occasion drops them! so far so good!

Of course reo is for crack controll, concreye is good in compression but rat shit in tension, if your ground moves then the top of the slab will be either in compresion or tension and the bottom of the slab will be in the opposite situation, delete reo in slab on ground at your own risk. Hear endeth the lesson.
