Need help to measure

[ger]

Hi need help to
measure cubic metres of soil
digging a hole for a pool
7.5 metres X 3.5 metre
1.9 metres deep one end 1.2m deep other end
how many cubic metres of soil will be
excavated??

Thank you

(((1.9 - 1.2) / 2) + 1.2) * 7.5 * 3.5 = 40.6875

You'd have to add for the thickness of the concrete as well though.
Assuming that it's 150mm thick, your calculations would be:
(((2.05 - 1.35) / 2) + 1.35) * 7.65 * 3.65 = 47.46825

somewhere between 70 and 80 cubic metres if you are figuring to get rid of it depending on soil type

thanks canetoad
it is half topsoil half clay
I was told it is 110 cubic metres
by the excavation co
sounds too much to me
they charge $2.20per km percubicmetre
to throw away

looking for cubic metres of soil
to be thrown away

Thanks

I was told it is 110 cubic metres by the excavation co, sounds too much to me

pawnheads' figures are close enough to be called the figure to work by, about 4 - 5 tandem truck loads.
I would be asking them how the heck they came up with their 110 cubic meter figure.

they charge $2.20per km per cubic metre to throw away

I would be happy to pay that (based on the approx 40m3) (if I had to pay

Where abouts are you ?

That's just the volume in ground, and there's no denying that it bulks up, but it certainly wouldn't double in volume. I'm no expert, but I'd guess about 20% for your average garden variety dirt. If it was very sandy, then you'd get bugger all bulking, but that's not very common.
Canetoad might be close to the mark for all I know, but 110m3 sounds way over the top to me. It sounds like a nice figure if I was getting paid to remove it though.

The last 2 jobs I have done have had swimming pools completed before I started my work (organised by client) and they both were told as horror stories, both by large Vic pool company. Basically said they were arrogant and a pain to deal with, dramatically increased prices and markups galore. When things were questioned they threatened legal action, the last client was a builder and found that the pool was 150mm smaller all the way round than specified, and coping that is not level all the way round, but they apparently have photo's that make it "100% accurate" to prove the work was done well

[Canetoad]

If you are concerned just count the truckloads. Most Bobcat combos use a ten metre tipper. It always throws me for a loop how much comes out.

for sure, hence the '4 - 5' tandem truck loads working on about 10m3 per truck load

the '10m3' figure comes from the weight on the load rather than the volume, but yes, count the truck loads. I would doubt it would get past 50m3 though (ie: about 5 trucks worth).

[pawnhead]

Terrian's got a compactor, and he spends a lot of time in the back of trucks whacking down each bucket load as it goes in. (Sorry. I couldn't resist that one. )

I'll leave this one between you guys because I'm no expert.

na, just know that around 10m3 wil take the average tandem up to its' legal weight limit

that and a 1/2 decent excavator operator will get the 10m3 in

when has that stopped anyone

I was at work at the time
my wife was there so she
has no idea on truckloads

Thank you
