Pre-engineered metal building (c 1992) with steel bar joist roof + girders? 4

[Ben29]

See image below. This is a pre-engineered metal building (circa 1992). I have not visited this building and I do not have the original structural drawings (not sure if I will obtain them). The picture is from the Long & Foster website. Basically I am trying to figure out if I should bid on a job that is associated with this building. It would be a heck of a lot easier if those were SJI bar joist in the picture.

Is it possible that the roof system was comprised of standard bar joist via SJI (steel joist institute)? Or is that just never done with PEMB systems? For instance, Butler currently offers this "Landmark" structural roof system which I feel is probably a proprietary truss system that looks like a bar joist.

Thank you everyone. I emailed the client and told them that this was a PEMB - I could tell from the photos that were available to me. I told them that if they could get the original building drawings which indicate the DL and RLL used in the design, then I could make a decision based on those numbers. But without that, I would assume that the roof is designed to the bare minimum code requirements, and thus would not work for a ballasted solar panel design.

I have not yet been paid a dime by these folks, and I probably never will. But that is how it goes sometimes. I'd rather get the bad news out of the way before I am under contract.

We worked for such a whale. Many "cake" jobs across the country for a large manufacturing firm.

Then they had PEMB failure (due to modifications made previously by someone else) and all the profit from years of work was lost in one lawsuit.

Tread carefully and limit your liability.

PEMB failure (due to modifications made previously by someone else)

This story might be apocryphal, but I heard of a PEMB that failed and the manufacturer blamed someone for building another adjacent building. They said funneling of the wind failed the building.
They must have a "Blame Others Department."
