site regrading question
site regrading question
(OP)
I have 350x150 industrial site. Site will be located open field industrial site.
Natural grade slope of the site is 5%. I have to re-grade it to 2%. The issue is I'm coming up with a huge net cut (7500 cu yd) and also the fill height near the existing road is 9 feet. The existing road doesn't have any ditch.
I can play with these numbers, if want net volume cut reduced I have to increase fill height near the existing road.
Is there an acceptable ballpark number for both fill height and net volume cut for this site?

the issue with that is i will have a very high fill height near the existing road.
from the existing road, my access road is 10% slope maximum and that will be the lowest point of site.
if the site is 100' from existing road, then i can balance the cut and fill easily.

even with 10% slope, i'm still getting a very huge volume cut.
if i use less than 10% slope, i'd have a bigger cut volume.

I don't think client would want the truck going in and out the site to go around but I can suggest that.

I agree with most other comments, sounds like your second option is to raise the fill to balance the site and use a longer access road. You can show your client both options and let them decide if they want to pay to haul off the extra material in order to shorten the access road length. It's generally not your job as an engineer to make these decisions, but it is your job to present all the feasible options to your client. You also should be prepared to present estimated costs for both options, which means you need to be knowledgeable about local unit prices for earthwork, asphalt, etc.

Nothing but the haul off as far as I'm aware.
Just so you're clear, at 12cy per truck you're talking about 625 dump trucks worth of material you want to haul off. Guessing a five minute cycle time that's 52 working hours of excavation. Plus you have to find a place to landfill it.
If there's another major fill project nearby you can sell the dirt to, it might be a real benefit. If not, I'd try to balance the site.
