If you need to figure out truck counts, I would...
If you have 1.5 TN/CY in place, 1.35 TN/CY in the truck seems reasonable, depending on the material though, because 1.5 or 1.35 TN/CY seem a little light to me. I'd use something between 1.4 and 1.5 for loose density. The yard where you are getting the base ought to be able to give you a good...
I have consulted on quite a few litigations that involved a variety of grading related issues. One problem I have seen as an estimator for grading companies and as a consultant is a disconnect between the estimating for a project and the reality of a construction project. If things get too...

I have been a big Agtek guy for years. I have seen too many engineer volumes out...
