Truss Mod & Repair

[itmw]

Hi,
I'm working on a project where I really "need" to carve out a half inch of wood from an existing wood floor truss in a house. There is a plumbing interference that would be much, much easier to work by trimming the wood truss member.

But, I know a little better than to just go shave a half inch off the side of the 2x4 diagonal member of the truss. I don't want the house doesn't fall down. The truss has 2x4s with metal plates.

I was considering adding a new member (2x4) parallel to the one that will be trimmed, and using adhesive (liquid nails) to join with the existing members. That can work at one end (where the metal plate doesn't interfere) but not the other side (metal plate covers where the new wood will go).

I see two options: (a) remove one side of the metal plate to install the support, then re-install, or (b) trim the end of the new wood to fit within the metal support.

The first requires removing an existing truss part of an installed truss (is that okay?), while the second wouldn't be using the full strength of the new supporting member.

Any thoughts or guidance? I think the "patch" will actually be overkill, nut would this be an "engineered" repair? I know these things must happen in residences a lot, but not sure how much people cringe at the thought.
Thanks in advance,
tmw

I am sure you won't be writing such number of lines if you and the owner have not looked at making a bend on some pipe ... is there any possibility of doing that without offending some too exquisite ownership or reviewer? Mechanical services sail on structural systems, point. This is not to say they are less important, just that one can't compromise life safety by just some debatable ideas on how an installation must be made, there being unbuilt alternatives. Here the home is in place, so think again in what way not to affect the structure.

For stubborn decisionmakers, you may do almost anything, such removing the connection plate. When you do this kind of things, you first support everything that is needed to the ground to ensure that no problem is going to occur. For there are those that are so daring, proud and willing to risk that have left this world in the intent.
