They said the calculations were wrong. The error may have been in one of several stages—design, drafting, etc., I can’t remember exactly. The calculations were not reviewed after the point at which the error occured.

That's gonna hurt.

Speaking as a retired design engineer.... 'those kind of things damage engineering careers'.

Question for any structural engineers: Isn't it SOP to load test any new designs?

They don’t know in which stage of design the error occurred. It is hard to believe these calculations aren’t checked and rechecked a few times along the way.
