Looking at getting an ensuite extension put on house, size is approx 1.5 x 3 meters. Have had quotes ranging from 6.5 up to 13 thousand for the slab.
Has anyone recently had concreting done and can comment on the going rate at the moment. I understand trades are in high demand at the moment but the price seems high for such a small job.
Concrete Slab Cost
Comments
have thought about it, am doing everything else apart from the plumbing and slab. don't really wont to risk doing a bad job on the slab and having it come back years later and bite me in the ass. not something you can really fix later on.
It's party time for tradies at the moment. I'm watching some new house builds take over 12 months. Previously in my area the time from breaking ground to key hand over was four months absolute maximum The progress on them is absolutely glacial. Supply of workers is low and demand is high, so prices have skyrocketed.
certainly appears that way, just seems like a lot of money for such a small job
It is possible to do it yourself, but you may need to think about a few things (1) Compaction of the underlying soil & getting it measured and certified (2) Position, quantity & type of reinforcement bar (3) position, routing of plumbing (4) Any cross fall/drainage requirements (5) Tie-in with existing house structure
If you’re comfy answering & dealing with all that, you should be fineMost concrete slabs for class 1 buildings/extensions require you to follow engineer specs and get inspected/signed off by the building certifier (at least they do in NSW). Usually need a professional and it usually costs more because of the need to do piering into the ground and/or screw piers etc. You would expect to pay more because concreters pretty much have to book the whole truck and pay for a minimum amount of concrete regardless of the size of the job.
Check out the hipages website for current estimates on concrete/concreting. Supply is approx $300 per cu. m. of slab grade (20 MPa). Laying could be up to $100 per sq. m.
You have 4.5 sq.m area, and 0.9 cu.m volume if 200mm thick slab. Laying $450 and supply $300 equals $750 total. Current labour/supply shortages might mean higher costs, but surely not a jump to 6-13k dollars.
Two local cement works in my area don't seem to have any shortage of trucks on the road, so I don't think there's any real shortage on the supply side.
Even 20 years ago you wouldn't get a structural standard slab of 4.5sqm laid for $750. Your maths isn't how it works in reality.
Hmm odd you say that. I had a 13m x 9m slab laid for a colorbond farm shed about 10 yrs ago. Total cost for the slab was $10k, located on the coast 100kms south of Sydney.
Regardless of material costs, various other costs will be similar for a 5sqm and 105sqm slab - eg, getting the concreter out of bed in the morning, they're not getting up for less than a grand, likely more if they can't fit in another job on the day.
so, 4.5m2 x .2m = almost 1m3 = avg $10,000 = WTF
50/50 chance any of those quotes are going to botch the job.Watch 20 youtube videos. Rewatch the one's with a clue.
Do it yourself. Save $9000 and tons of heartache. sselecirP
Cost? About tree fiddy.
Just to give you all an idea of what current cost are, this is from the 6.5 quote.
for the 20MPA concrete just by itself has been quoted at 1,000
and the concrete pump is 1,500
Machine to dig, Bin to take away excess dirt. Rebar F72 mesh, Pods they'll have to fill where the plumbers jacked existing slab to tie in waste DWV.
You'd be lucky to get a 6mtr Skip for $700 before they even start to dig.Idiot rings a brickie
"hello I just reversed into my letter box and knocked out 4 bricks can you come and fix"
Yeah tomorrow arv $200 cash
I thought you brickies only got paid $2 a brick!
You could do it yourself?
