Earth Bag Foundation for a metal building?

I was wondering if anybody has a good idea about connecting an earth bag foundation to a metal building? I am looking at buying a metal building from Duro Span Steel Buildings. I am not planning on putting it on a concrete slab. I want to have a crawl space underneath the building. The steel building that I am thinking about getting has steel base plates (I will attach the base connector manual below). I am wondering if there is a way of either attaching a concrete layer on top of the earth bags to have base plates sit on. Or doing it with wood? Base plates have to sit on a 10" width foundation. Thanks for taking the time to read this and/or responding.

I am getting the Q series
Q35-17 Model 35’ Wide x 40’ Long x 17' High

Number of arches: 19

I hope someone with more experience will be along to provide a more substantial answer, but wanted to suggest you take a look at this: http://www.earthbagbuilding.com/articles/bondbeams/bondbeams.htm#reinforced

This concrete bond beam would generally be used atop a wall and then have a roof attached to it; how much alteration of the earthabg wall and/or the bond beam would be required to sit an entire building atop it, I do not know.

Dillon Nichols,

Thanks for the response. That link was awesome. Now the question is will it be strong enough to bare the weight of the metal building? The metal building is an arched building (quonset hut). Hopefully an engineer can respond.

Hey Phillip,
Concrete bond beam, wood or metal sill plates are all appropriate options. Depending on the q hut finishing and insulating plans, I personally
Would hit up my local scrap yard for some appropriate, maybe welding angle into a ladder type plate. But they all can work. Consider also strapping or pegging short rebar as attachment.
Kelley Hart built a Scoria bag footer and stem wall under his old q hut (subsequently covered in Scoria bags to insulate the metal building). It can be seen here:http://www.earthbagbuilding.com/plans/carriagehouse.htm
