I have the impression that this EE will be responsible for design as well as installation and maintenance,that being the case I would require that he have his PE license so he can seal/approve the design drawings.I am also a firm beleiver that the EE should be responsible for the installation and testing of the design,thus I would expect him to know the order of the bolt, lock washer, flat washer and nut.
Just my opinion of course.
