Calculating Pier column diameter

[Tommy5725]

Hi all,

I'm just getting ready to build a Perka hybrid building model 4000. My codes officer required New York State stamped plans for snow loads, wind loads, and all that. I received those today. I live in central New York.

I was wondering if anyone knows foundations and load requirements? The codes officer seems willing to hear out what I have in mind. But I don't really want this thing to fall down either, lol. So being I've got the building plans and loads I was hoping to find somebody that could take a look at those numbers and give me an idea what size cement piers I should go with. Or, at least a ballpark. Ground is clay/gravel.

Thanks for any help,

Hire a structural engineer licensed in NY.

To expand on JLNJ's post - this forum is for professional engineers (or junior engineers on that career path) to discuss technical problems and collaborate to find solutions. What you're asking is for us to do our job for free. We're not going to do that for a number of reasons - we all want to make money and won't start undercutting our New York brothers and sisters by doing it for free because we don't want people doing that for potential clients where we are, and because we don't want to be held liable when our free internet advice is misapplied.

The idea that the code official would require engineered plans for the superstructure but let you wing it at the foundation seems dubious. He may be willing to hear you out, but I have a feeling he'll still come back and say "That sounds great! Now show it to me on a sealed foundation plan and we'll issue the permit."

Best bet is to find a local structural engineer to design the foundation.

Okay. Thank you for your time and the explanation. If you have a number of someone in Central New York I'd be happy to give him a call thank you.

Tommy, try google.

Lol, I tried that. most of them aren't even structural engineers even when that's what you're searching for. And the ones that are I'll say that they do something different. Being I don't need stamp plans I'm just looking for somebody to pay to look at the numbers and give me an idea of what diameter the cement needs to be. I already know it's got to be 48 in deep to go to the frost line, codes told me that. All I need to know is what diameter and what size rebar. The perk of people that sold me the building said that they'd have stamped engineered plans for the foundation for an extra $1,800 on top of the $1,200 I paid for the stamped engineered building plans. Seems like $1,800 for somebody to tell me what diameter cement peers just a little bit ridiculous. But hey it's the world we live in. Thanks for your help.

Seems like $1,800 for somebody to tell me what diameter cement peers just a little bit ridiculous.

If they have to visit site and do some soil testing to determine the foundation design, $1,800 sounds OK to me.

I couldn't agree more.
