A supposed structural engineer on a Caribbean island has done some strange work
(OP)

Besides this strange square meant to cast within the butt there is a four foot length of I beam augers into the ground without any rebar webbing cast directly with concrete. He intends to utilize these to attach ibeam posts about 10ft high and support a floor slab of concrete foundation about 15 cm thick and 900 m2. He has created 4 corners with these and two central ones.
I am quite confused

There is no way we can give proper answers without seeing the bigger picture. It may be that the guy is actually a genius, or a horrid engineer. Without seeing the rest of the intent of the structure, we do not know.

The 900m2 building is divided into two with half having an excavated basement and half at ground level(benched land)
Both halves have 6 butts as shown in the pic laid in auger holes about 4-5 ft deep with smaller ibeams connecting the butts and cast with concrete (with out rebar, just ibeams in concrete). The intent at ground level is to cast a foundation slab of concrete on top of this support.

Maybe not how I'd do it, but I can see how it could work.

Otherwise, if the files are large, can you put them on a sharefile site and then link the URL with the link attachment?

(Not saying I could personally do it better, but I also don't advertise my ability to do so and get paid for it...)
