With my old school ways I was about to start digging and filling sono-tubes. Then I discovered these helical piling thingies. Don't know yet how many needed or how expensive to install, but apparently they go in extremely fast. Somehow I get the impression that many will be needed for the same job, so the cost is probably higher considering the shmancy twisteroo required to put them in. Apparently they conform to Nat. Build Code, but nobody seems to use them locally--What's up with that.

I guess I'm as curious as answer # 3; though I realize full well that many single level houses are built off ground level. I assume the rest of the structure exists that way already?
Even for the Sono Tubes however; I'd want to check with Zoning and code regs, people before doing anything. Certainly not knowing at all where you are; soil; composition; budget; etc. it's difficult to arbitrarily advise.
Many places around the country, and here in Florida in some locations; PILING houses are often built just high enough to offer crawl space, and often the PILINGS aren't much more than appropriate depth footers; and concrete block.
Early in this decade I rehabbed a small house in the woods in WA. State, built in 1905 on just the stumps of the trees cleared to the size of the house. The ground was rocky and compacted; but I just did footers and block.
I'd probably determine how the rest of the structure is built, and go from there. I hardly think it neccesary to do pilings on every floor beam; but there again; code and zoning may be what dictates.

Hey Thank though you were talking about trailer tie downs, but used the (research your answer) at the bottom of the page. I do not know anything about the HC pilings but do you live in a swamp. Why would you need piling for a 12.5 ' addition. Here in Florida you can get by with a concrete footing. But if you are building by a permit I would guess that you had to get bearing tests to see how much the ground would hold. I guess that a lot of the stuff that I learned over the years have changed after the hurricane

Helical piles are proprietary and depending on the "Authorized Installer" can be more expensive but should not be as they are better than the old fashioned way. Much less excavation needed. Most companies will provide engineer stamped drawings for liability, finance and insurance paperwork. I have seen them used both under and over, often depends on if an Architect is involved.

I can't really help you with how many you'd need, but a reason why they may not be used might have to do with insurance. Some insurance companies will not insure you if your property doesn't conform to their own building code. This is something you should probably check in to before building.

This may be 7 years too late, but any local contractor who wants to see the engineered blueprints before giving a quote are most likely good contractors. Helical pile pricing is extremely dependent on amount of piles needed and depth required, as well as other important factors like size, capacity, etc. As frustrating as it is, it is irresponsible and and frankly, impossible, to give an accurate ballpark estimate for helical pile installation without the engineering, and any contractor that is willing to give you an estimate without it should not be trusted.
