That argument is, excuse my language, bullsh!t. I wouldn't sign off on it unless the timbers were massively overdesigned and I knew that I could make the job work with absolutely lousy wood. 

The best thing to do is to make him get the timbers graded and accept a letter of grading from a properly trained expert.  Let him know that if the grade is weaker, he'll have to pay for a re-analysis and may still need to get stronger timbers based on your new analysis and the timeber grade he has.

I designed a small wood dock structure supported on 8"x8" timber elements. In the contract documents, I specified that the each piece of lumber shall have a grade stamp of grading agency.

The contractor provides timber elements without any stamp, arguing that the timber are "rustic" elements.

Is that argument acceptable?
