Cost for concrete base
Discussion
Hi Chaps,
Can someone give me an idea of cost for a concrete base.
Dimensions 10ft x 30ft, the ground slopes by about 1ft -1.5ft over the 10ft width, it will need this side levelling up.
So cost for digging out (no dirt removal cost), hardcore and concrete plus shuttering work.
It's for a container which will eventually be clad in cedar and look quite tidy so want to get a good base down rather than a few sleepers.
Thank you.

Can someone explain these prices to me please? I’m not sure how thick a slab the OP needs but based on the length and width stated and a thickness of 1ft the total amount of concrete is just under 10m3. A quick online search suggests a price of £100-120 per m3 plus VAT so let’s say £150/m3. That’s a maximum of £1500 for the concrete. How the hell does a bloke with a shovel and wheelbarrow plus a £300 skip get that price up to £5k? It’s only takes a day.
Look at the job spec in more detail.
Ground needs laying out, levelling and dug out for the hardcore base. So that’s a couple of days with a digger and dumper to lose the spoil.
Then bring in the hardcore, put it down and compact it. Another couple of days with the 2 bits of plant.
Then build the shuttering, another couple of days to bring in the ply, cut it up, lay it out square then brace it all.
Before you get to the concreting.
Now look at all the man days and materials above and add the VAT.

At 21cm deep concrete you’d need 6m2 or 27cm deep you need 8m2 of concrete so 6 or 8 x £130 = £780-£1040
You’d want reinforcing mesh sheets c £300
12 tons of sub base 12x£45 £530
7 scaffold boards at £25 = £175
Digger, dumper and driver to dig out / level hardcore £280 (8 hrs @£35 hr)
Wacker hire £100
Level concrete upon delivery £280 (max) half day x 2 people
So circa £2700 + vat approx

Yes, thats a reasonable list of some of the costs. You would also need someone to accurately install the shuttering etc, and have access to all of the small tools and fixings required.You’d want reinforcing mesh sheets c £300

I would also assume the Op does not have the skills or experience, nor does he have access to labour who would deliver the project in the limited hours to complete the job you have allowed.
Therefore you want a contractor who must expend approx £3k, bring his plant and labour to site, have access to all of the small tools and fixings, guarantee his work, hold adequate insurance, and pay all of the relevant taxes on the transaction. They might also like to make some money on the job.
So I would suggest a contractor like the above will not be short of employ. I would think £4k is more than reasonable.

Just to check, we are referring to a concrete base for a shed, aren’t we? I just wanted to check I haven’t stumbled into an obscure section of Pistonheads where you’re designing some kind of super gun to fire 600mm shells at the Russians.
It’s a proper concrete base for something of substantial weight, that needs to be built onto sloping ground. He wants (correctly) a decent job. We’re not talking about 75mm of mix held together by a few planks. The shuttering alone will need a decent amount of time put into it to ensure it doesn’t fall apart under the pressure of (literally) 20 tons of mix.It’s not a base for a shed. HTH.

To clarify, it's not a shed, it's a shipping container holding about 5 tonnes of agricultural machinery. I want it to last a very long time, be level and fit for purpose. I shall clad it, so more weight. I don't want half a job.I probably have the skills to do it but not the time.
Here’s a thread showing some idiot doing a very similar thing a couple of years ago.
It’s a not inconsiderable amount of effort and materials.
