Routing heat ducts through engineered joists?

[interalian]

My basement renovation is finally underway. Yay!

I want to re-route two 5" heat runs through engineered joists to eliminate the need for an ugly bulkhead in the main room.

I've done a little research and have found that cutting holes is permissable but no closer than 4' from the point load/bearing wall/beam to preserve the vertical load rating on the joist. The proposed re-routing would work within this restriction. My joists are 12" nominal with 9" web.

Can anybody confirm? Location Canada if that makes any difference.

Thanks in advance!

Call the manufacturer of your I-joists...they are the ultimate authority about what will work WRT the allowable size and location of any holes in them.
