Thanks again. They will be using a rock subgrade. I should have took some pics but we cut a hill down @ 12 ft to get to the elevation they wanted. The owner, who was running one scraper, wanted the building to sit on 'virgin ground'. We basically cut it down to about 6" above grade then did like td25c mentioned and parked one scraper and had that guy just shoot grade and paint how much we needed to cut on the ground until we got down to 1-2" above grade. Then we just used one scraper mainly because the other scrapers had a lower center cutting bit on them. We did get it within 1/2". Since then we have gotten @ 5 inches of rain. Other than one little puddle @ 1" deep and @ 4' in diameter the rest of the pad was high and dry.
