Footings

OK, I didn't find a good place to put this so here is the best spot.

Just scored a 40 foot Sea-Land container for storage, now here is the problem.

It will sit on a good solid footing at the front (the end with the doors) but will be 28 inches off the ground at the back end, it by it's self it weighs in at 8200 pounds.

So taking the old engineering standing of 1/2 the weight (4100 pounds) in the front and 1/4 on each footing in the back (2 footings with 2050 pounds on each) and lets say another 2000 pounds divided between all.

How big should the 2 end footings be???

I come up with a 16" x 16" x 6" base and 12" diameter columns , does this sound right to anyone else?

i think it depends on how much weight you are going to put in it.

Holy Moly. If I were you I would ask someone in your area. The soil will be the determining factor.
