I don’t disagree with any of the substance of what you said (as someone who has also had tangential experience in sewer rehab work), but it’s worth pointing out that ASCE has a vested interest in constantly throwing out the “nearly failing” grades. I have never taken those reports seriously (even as a card carrying member) and I suggest nobody else do it either.
