RE: Pre-Engineered Metal Building Foundation - Ballpark Design

Bill:

We have also noticed that unless it is a large project, it is difficult to
get a metal building manufacturer to give us preliminary reactions. We have
resorted to running our own frame analysis  with conservative loads (don't
forget to seriously look at uplift since this condition sometimes controls).
I would much rather be conservative with footing sizes the first time around
then to go back later and explain that the loads from the metal building
manufacturer were different than what we first assumed.

As far as pier details, I make them as generic as possible. I detail the
pier so that the contractor must provide a pier size that is equal to the
column base plate size plus say 6 to 8" (whatever you prefer), but it not
less than say x" by x" ....with minumum reinforcing of..... This puts the
contractor on the hook for the correct pier size. He must coordinate the
actual pier size with the shop drawings of the metal building manufacturer.

Good Luck!

Subject: Pre-Engineered Metal Building Foundation - Ballpark Design


Greetings.

I'm running into these kinds of jobs from time to time where a developer or
owner wants to proceed with a building which is all or part a metal
building, and needs as much engineering done as possible to get the building
permit, expedite the schedule, and sometimes even for financing.

So, we have an architect's plan, and it has been sent to the metal building
vendor(s) for a quote. We have a geotechnical report. And it's enough for me
to get about 80% done with the foundation, but what I'm finding is the metal
building guy doesn't want to bother with any sort of preliminary design,
understandably, because he doesn't even know if he's getting the contract.
So of course I have no reactions, no base plate dimensions, etc.

I have to explain to the contractor/owner/developer/whatever that I can get
"almost there" but not all the way, and they are puzzled because, of course,
they think all this stuff is just cook-book and only needed because they
can't get a permit without a sealed drawing. Most of the time they're
patient (with the subtext "man, these engineers are a hard bunch to deal
with"), although a few times they've been downright hostile ("I've never had
this problem before. Are you SURE you know what you're doing?")

Anyway, I wonder if anyone else sees this from time to time, and how you
deal with it?
