What Kind of Foundation?
 
I'm building a new house and the pad is ready. There's about 3' of new/loose fill on one side and 2' on another. I think I've ruled out a monolithic/post tension, since it doesn't sit very deep. I've been told I should go with a footing/stem wall, and put piers on the two side with the loose fill. Are the piers necessary if the footing is deep enough? Any other suggestions? Thanks!

Were not even allow to build a monolithic slab in my area. Not even a garage.
A stem wall will help to get the walls higher and away from the grade. If you look around at some of the older post you will see where there's dozens of people with slab on grade homes with water getting in under the walls and rotted siding.

I'm at a loss when you say the pad is ready,then go on to say you have loose fill on two sides and also don't understand the footing/stem wall with piers on the sides with loose fill,when a foundation is poured it's usually four sides all the same configuration,can you draw a diagram or post a pic of what your asking about,your entire post is a mystery to me,and i would say others also as your not getting any replies

Here's the lot. Sorry, I haven't made my question clear. I know the footing goes all around. My question is the two side in the pic where the pad has been "raised" to make it level, the 2' and 3' arrows. This is what I'm calling "loose" dirt (not original, not yet compacted.) Because it's freshly graded, do I need a deeper footing and therefore a taller stem wall to get down to more stable soil? Thanks for replies, sorry I haven't been clearer.

I think you need to get a better set of drawings, specifications and over-all design to save money and future questions or conflicts as you go on.

Call a designer, architect or engineer as soon as possible.

Makes more sense now,that whole pad needs to be compacted before they'll dig for the footings,and the piers you refer to are more than likely going to be inside the foundation spaced in the center equally on the long demension,i'll attach a link with pics so you can get a better idea of what it looks like,i think the bottom pic will apply to your job.
