saturated composite lumber
(OP)
Does anyone have experience dealing with parallam beams tji's that have become saturated on site during construction? I-Level literature and their reps imply that everything will be fine once the members dry out, but some members are swollen and delaminating, so I'm not so sure. Intuition tells me the wood/glue bonds must be damaged with a corresponding reduction in strength and stiffness.

I would also contact your client (Architect and/or owner) about the whether they want to allow the use of the materials without a clear statement by the manufacturer that they are still under warranty.
I am not sure, even than, that I would want to take the responsibility for the members. I could review the information given, to see if it meets the specifications.

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.

Saturated lumber - esp "engineered" is usually pretty much ruined. For one thing - even if it somehow maintains it's strength ( and I doubt that) - it will never be dimensionally correct again!!! It expands and won't "go back"

As mentioned above, a little wet is a whole world different from totally saturated. Also, I have seen engineered lumber's dried state after being totally saturated, it doesn't revert to its original dimensions.
