220,000 yards of fill
(OP)
Does anyone know how long it would take a grading contractor to move and compact 220,000 cy's of fill. All the fill is coming from the same site and will not have to be moved more than 1,000ft (this would be the longest haul.)

That said, it took about 4.5 months. Try to set it up so the contractor can use really big trucks!

second - determine the cycle time to excavate, haul, place, compact and return for another
third - estimate how many pieces of equipment could be mobilized - call your local contractors to see what they say
fourth - determine hours per day/per week/per month etc you can work.
Assuming 10 scrapers, moving about 50 yards per hour per scraper - you will move about 4,000 yards per working day. With no down time you could do it in about 11 or 12 weeks

Of course, if the site is bigger your production could be much more than 4,000 yd3 per day -

RE: 220,000 yards of fill
Firstly, and I am assuming that this is a given, is that you have a complete understanding of the project. In other words, you have done the geotechnical and design and understand what needs to be done.
Secondly, now you have to think as a potential "contractor". You will have to assess how the project is to be tendered (locally, regionaly, nationally) and from that point try to estimate the availability (and size) of earthmoving equipment.
Thridly, now will be the task to reasonably estimate how the job is to be done. By this, you will have to develop a methodology and think about how the most competative bidder would do the job. I have awarded low bids to contractors whom have work 24 hour shifts to complete earthwork components of highway construction. 200,000 yd3 may or may not be a monumental task, but it will depend on local conditions and equipment. If there is a completion date, then it will make things a bit easier, but if you are trying to determine a reasonable completion date, then I suggest using my method.
It also would be advantageous to sit down and speak with a few contractors on their ideas or approach. You may get some valuable insight for your purposes.

Both KRS and Focht hit on aspects of the process that need to be considered. Depending on many factors, it could take from 3 months to 3 years. more information is needed to provide a reasonable estimate of the time.
