Thank you for that. Seems like the specific engineer(s) responsible for those particularly calculations, and any engineer tasked to review those calculations should bear some personal responsibility and consequences in addition to the firm.
Quite a few decades ago - when I was just a tyke - my father worked for an engineering consulting firm. Even though he wasn't an architect, it somehow fell to him to design some sort of industrial building or warehouse. He looked up the information he needed to on things like roof spans and snow loads, and drew up a design which was subsequently turned over to the customer, who hired a separate construction company to build it according to plan.
They didn't.
Sure enough, after a heavy snow, the roof collapsed. Hungry lawyers came to the consulting company, and my Dad was called on the carpet. He and the management team went out to the site and my Dad noticed - the building deviated
significantly from the blueprints he'd prepared. Something along the lines of substituting 5" beams for the specified 8" beams AND increasing the spacing. Since my Dad's company had nothing to do with inspecting or managing the actual construction, the lawyers shook their heads, went away, and the customer went after the construction company instead. Dad ultimately came out "smelling like a rose" - he didn't even have to testify since the deviations from his blueprints were so egregious..
Dad shortly thereafter quit that engineering consulting company - he didn't much like their readiness to throw him under the bus, and he figured if it happened once, it could happen again.
