Miami - Broken Roof Trusses
Miami - Broken Roof Trusses
(OP)
The company I do some work for has a one story building in Miami. Wood walls, and wood trusses. About (5) trusses have chords that are broken. The span isn't huge, only about 36 ft or so.
They are getting bids from contractors for doing the roof and truss repair.
My question is this: In Miami, is this something that would trigger an engineers stamp of approval to repair broken trusses with plywood gusset plates? I haven't had much experience down there with this, however, a recent truss issue in Oregon required my stamp of approval before the contractor could build.
Thanks.

I'd say call them, but you're likely to want to blow your brains out right after that.

I spoke with one of the contractors earlier and he said he does little truss fixes like this quite regularly in Miami and hasn't had any issues with the building department asking for engineered calcs. Seams a little surprising down there but every place is different.

"2303.4.5 Alterations to trusses.
Truss members and components shall not be cut, notched, drilled, spliced or otherwise altered in any way without written concurrence and approval of a registered design professional. Alterations resulting in the addition of loads to any member (e.g., HVAC equipment, piping, additional roofing or insulation, etc.) shall not be permitted without verification that the truss is capable of supporting such additional loading."
So trusses are okay to repair by anyone as long as the repairs do not add additional loads, cut, notched, drilled, spliced or otherwise altered the truss?

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

But yes it should be engineered. I also wonder what would break the chords.

Maybe an alligator was lifted into the sky by a tornado and dropped onto the roof a few years ago?

Are you really going to repair broken chord members with plywood gusset plates?

Might be easier to just replace the trusses. They are replacing the roof tile anyway, so to remove part of the old sheathing underneath and drop a couple trusses in might be the best way to go.

In this question is probably the answer. Seen it happen a lot.
