Re: 3/8 inch shear panels

It would be ethically correct to contact the engineer and discuss your point before going to the Client.  In Canada we are obliged to inform the engineer that we have been retained to review his/her work.  Personally I find it professionally and humanely better to first review the discrepancies with the engineer.  The engineer may then, on his/her own recognizance  "rectify" or revise the details to conform with the third-party input.  No-one gets "pissed off" (unless there is a battle of wills) and the resulting design may be improved.
