unit price of earthwork

[Silty]

Hi all,
Can anyone help me in preparing price estimate for earthwork for building a large embankment.
I know how to get unit price for material and haulage from pits, but is there any rule of thumbs about how much placement, compaction, and QC will cost.
The site is far from my area of work and I do not know any contractor in that area.
Thanks for your replies

In the states I'd use the Internet to search for contractors and then call one or two of them for some help. Chances are they might look at this as a possible job and thus will be quite helpful. It always is nice to have friendly relations with contractors, because never know about future contacts.

Thanks Oldestguy, I appreciate your reply and will contact them.
Is there any rule of thum that how much QA/QC of an earthwork project should cost?
Thanks

Testing cost is ighly variable. It depends on the owner and his policies. A strict owner and a fancy job is more expensive than a municipality or public agency that is pinched for costs or a job that might not be high value,etc. Again, those contractors may give some idea, but finding a local testing firm and describing the job, you might get some usable results, again depending. Google search for "Soil testing" and locality.

Don't forget you may need QA/QC at the source of the embankment materials as well as at the site of placement.

Thanks for reminding me, I will consider pit sampling as well.

strict owner and fancy job:
Contractors QC - $1.7 million for 1.5 million yards of earthwork, which included full time inspection, sampling and testing with field lab
total bid - $33 million

owner had his own QA program

Are you looking for cubic yard cost for soil importation and exportation -

The cost of moving earth is related to the distance from the x to y. A truck costs depending on where you are $50 to $100 per hour, determine the haul distance and how many trucks required. The remainder of the project is pretty easy to estimate as they all wait on the trucks to arrive. The truck delivers its allowable highway haul weight of lets say 20 tons which equates to 10 m3 using the good old 2,000 kg/m3 estimate or use the anticipated compacted field bulk density.

The other parts include dozer/excavator, compactor, grade control/survey guy, nuke guy, lab tests per so many cubic metres. These items wait on the trucks for a daily rate and are efficient when paid by the m3 and slow when paid on time and materials.

In my area general rule of thumb paying by the m3
close and cheap material $30/m3
about an hour roundtrip and screened or crushed material $60/m3

I would also recommend looking up public government tender results in your area to determine what the contractors are bidding.
