Not sure if this helps but I just priced a concrete pad for a new warehouse (50x100, 8” pour) and it’s gonna be close to $50k. That includes some pretty deep footers though and 1 6x6x6’ footer for a jib hoist.

I haven’t priced the building yet though. I’m thinking it would be better to buy the building kit from the manufacture and contract out the labor to erect.
