Pole Building-Pad

[CBOT]

Hey there!
We are planning to have a 40x50x16 with a 12’ shed roof on one side. I’d like to elevate the building site about 12-15”. The guy who came out to bid the project said we could use pit run/bank run to build up most of it and then finish it off with some 3/4” crush road base. After spending all of last summer drilling post holes for fencing, the last thing I’d want to run into is pit run?! Do these skidsteers with augers just blast through rock? Thats my main question. Do people typically build a pad using 1-5” pitrun? I just want to make sure I am understanding him correctly. Pit run is the last thing I want to run into, but it is way cheap in my area so I want to make sure I’m not getting overly excited.
Thank you!

Nope. I have a pile of worn out auger bits to prove it.

I'll bet he is not really getting that you plan to drill through his new pad for structure poles or he doesn't care since he will not be doing the drilling. Without knowing who is building for you, I will tell you that some pole buildings utilize a mount above the slab for attaching the poles to. I know Morton offers that option, similar to how a metal red iron building is installed. I do not know if a footer is required around perimeter with that style construction.

I need more information before I can confidently offer an opinion.

Start with your location.

We will be building in Northern Idaho. These guys set a the posts in cement and in the hole. They don’t use a bracket system on top of the cement base.

A normal auger? No. But here we have a ton of limestone and a medium to large skidsteer with a ROCK auger - absolutely.. That's what we use for post holes here. Takes a lot of pressure, but rock augers cut it.

If you're on something harder than limestone, no idea.

Depends on the rock, my contractor had a rock bit, it went about as far as the standard bit. I ended up digging them with my mini-ex. I had to bring my grade up a little, I used 3/4 crushed minus as it was the cheapest at the closest pit. Hauling to my site can get costly otherwise. Here is a pic of one of the holes, 16 of the 24 were like this, solid red basalt and ripped it out 4 or so inches at a time.

I have limited experience building pads, but the ones I have been involved with were #2 crusher run limestone compacted in 6" lifts. The building I am pricing now will be a minimum of 10" stone at one end and ~24" at the other.
