You better have a slab that can at least take 1.5 times the load you put on it!

But bear in mind it is just my little engineering brain that tells me this. Load plus safety.

I also think you should make the support wider than the 1.5 m.

I'd go with a concrete slab with cement in it. But again not sure about this.

Hopefully you can give us some more information about the die head and the surroundings as I might miss some vital information from your post with my answer . . .

Without knowing what the ground conditions are, how about a dozen concrete railway sleepers laid huffalo-dowd?

you might be fine but consulting a website such as this isn't your smartest choice. no one here knows what the original soil conditions were, no perk test, no slump test, no PSI ratings on the concrete that was used, no reinforcing data, etc, you simply have a diameter which resally tells you nothing.

1" thick steel will work fine.

Since you give no useful information, make it 2" steel just to be safe.

First off, the OP has not shared a great deal of info.

The biggest question in my mind is whether this slab is on-grade, or a suspended one?

Also, why is the OP using 2 different measurements systems? Or is that METRIC TONS in lieu of standard English tons? It makes a great bit of difference!!!!

No in-situ soil composition data and allowable soil bearing strengths. No mention of concrete and rebar types and strengths. No mention is the piece of equipment is rotating or not....vibrations (due to equipment going out of balance...and yes that is a primary design condition concern!) will undoubtedly increase the size of a foundation or a suspended slab. Will vibration isolators be installed?

My list goes on and on......

First, where to you want to do this?

(Who/what) agenc(y/ies) (has/have) approval authority to permit such a structure?

What local, state, regional, and/or national Codes apply?

Where is the (geotechnical report)?

Why is there not a consulting (Structural Engineer) involved yet?

How does the proposed slab (fit) into the existing facility as said facility currently (operates)?

What is the range-of-activity of the proposed (equipment), after installation?

Etc., etc., etc, ...
