NEED A FAST RESPONSE ON THIS ON
This picture came from a townhouse I did today that was built in 1982. On the right side of every truss the builder had cut the top web and then tied it back together with a gusset plate on each side. There was no support under the cuts at all. I did find a spot that looks like it could be a sign off by a SE.
Comments please.

Peter,
I have seen endless truss packages come from the manufacturer designed and built that way. The metal gussets are designed for that purpose and if installed properly (machine pressed into place not hammered) are strong and adequate.
I would not be concerned.

I would think that if they were machine pressed, they would be more uniformed. The first one in the picture appears to be pressed almost above the truss. As I said in the photo I attached, it looks like the sheathing is separated from the truss in the spliced areas.
I wonder what it looks like from the roof?

They came that way from the truss manufacturer. I see this all the time. Cut trusses are a problem when a section has been removed from one of the chord members and the truss is acting like a rafter and not in concert with all the other parts.

I agree that the trusses were built per design. It is normal for the trusses to be cut in the exact same spot, as your photo shows. They set up a template and layout each truss individually. Then they have a huge roller (or press) run back and forth over the truss. Then they repeat.
By the way, if you have a multiple ply truss, the breaks should not line up. Also, multiple trusses should be nailed or bolted together at regular spacing (8d at 12" o/c). The spacing at the top chord, bottom chord, and/or webs can be different.
By the way, I was the engineer of record for a truss company for a year or so. I learned more than I ever wanted to about trusses...and what can go wrong.

The fact that there is a gap above the nail plate indicates that the truss was built that way. The gap is there because the nail plate held the plywood away from the truss during installation of the plywood. I see poorly aligned nail plates on trusses frequently. I would not have written this one up.
With regard to the plywood clips, between 1986 and 1993 I was on several professional framing crews, and we never used them. I am not sure how long they have been in use.
