I haven't seen any specs for a footer on a lift yet but I could always be wrong.You should get the footer info from the lift company before you pour the floor. Pretty sure you will need footers for lift.
Thanks, I hope explaining the process helps some people in the future. It has taken a lot more effort and planning than I expected.Great! I'm also planning to build one.
Ya, it is weird that they aren't really specific about it. BendPak is the only one that was super specific especially if you have inadequate pad and have to cut in a pad. So far from everybody I have talked to and researched I am way good. I even hit up a guy selling lifts on FB and he said what I had spec'd was plenty.Surprising that they don't call it out, my oops. Maybe they are deferring to the Engineer, I would.
The gray area in between is where all those gray hairs come from. If the standard footing is 2x2 feet, then the load capacity of the footing should be at least 10,000 pounds (2 ft. x 2 ft. x 2,500 pounds per square foot), and perhaps even more if the soil has a bearing capacity in excess of 2,500 psf. You can probably support a little bit more given that 2,500 psf is a fairly conservative soil capacity (unless you built on muck) If your column load is more than 12,000 pounds, or if you’re not really sure there is a 2x2 footing, put in a new one of adequate size.
