I'm not quite sure what you mean by this statement.  Are you implying that if
you did a calculation based on Ultimate Strength (load factor) design the
calculations would show that the precast concrete plank is not strong enough?
 Yet, a manufacturer will state that their plank is sufficient for the
application?  How do the masonry walls you mention play into this?  Do the
planks calculate out for uniform load, yet not with localized partition
