Let me know if you think this is sturdy enough.
Building my 10'x14' shed in the near future. I was planning on going with a slab but we got a lot of rain recently and found my entire lot floods like a retention pond so I need to get my shed up in the air, the old one had 10 inches in it... YUCK!
I was thinking of doing 12 concrete piers in a 4x3 pattern so no span is more than 5'. The piers will be 48" deep, 42" in the ground so they are to the frost line and 6" above to prevent water damage. I was planning to use 2x6s for the floor joists with 3/4 plywood for the floor using 16" OC construction. Do you think this is beefy enough to park my 750# lawn tractor on? Also do you think I need and if so what size support beam to run under the 2x6s and sit on top of the concrete piers? Or should I just beef up the 2x6s and skip that level? I cannot find much online about this, it is a popular deck construction method but people do not really park their lawn tractors on their decks!
I would like to keep the shed floor construction as "slim" as possible so I don't have to build I giant ramp while obviously having it off the ground so I am keeping as much of the bottom dry as possible.
P.S. Not a professional by any means but I am having it built by one. I just like to do my homework beforehand!
