New construction
I have not seen this type of design before, looking to identify what it is called and more specifically what the horizontal 2 x 4’s are called that are installed between truss, 1 is damaged. Included is 2 pictures.
from client during build with red circle
from my inspection.
Any concerns with this damaged 2x
Those are piggyback trusses installed over regular trusses.
They set on top of furred 2x4’s at 2’ o. c. The damaged one should be replaced if it impacts the bearing of the top truss and also provides lateral stability of all the trusses also.
Piggyback trusses are utilized when there is a height restriction on transporting over the highway.
They don’t have typical structural attachments that we see in this area either. Those 2x4’s are permanent lateral bracing… the damaged 2x4 looks like significant damage… new construction, you need the TDD’s to provide your client with the best information.
