Foundation for modular field office

[Hoboneer]

For the purposes of foundation, would you treat a modular field office (think shipping container type with a door and window) as a regular structure and provide footings with a minimum depth for frost per local code?
Or you would you think of it as an "equipment pad" and just do a slab with a perimeter haunch?
The office will be permanent.
Does the code address this anywhere?

I think the answer is obvious
It's a permanent field office - you should design footings as per a regular structure
Presumably frost is an annual event so you'd hardly want this thing to be heaving annually?

Short answer: if the soil frost free material , just excavate the top soil and provide a slab with a perimeter haunch,

Long answer : Pls look Int.Res. Code ,FOR ONE- AND TWO-FAMILY DWELLINGS and provide more info.( frost depth, soil type , GWL ..= to get better responds.

Check out shallow foundation design for frost protection.

It seemed obvious, but when I started thinking about it in terms of an equipment pad it became confusing. Why aren't we concerned with heaving for equipment pads? What guides the slab with haunch design for those?
