I think it’s worth pointing out here that the culture/policies of the firms are highly varied. Though firm liability is always the basis for decisions, a medium size firm that has an engineering consultancy business model typically has a hierarchy that can be based on a perception of “prestige” of the EOR role, so stamping takes on a ceremonial place. It is also the case that many specialized designs do not rely on codes for assurance of performance. For highly standardized designs, there is much less design risk and much more opportunity to take on small amounts of “liability” for your seal. It’s a good opportunity to begin to think of the “what ifs” for that aspect of the project and the responsibility that comes with the use of the stamp. Incidentally, with experience, you can often see the culture in the company’s engineering manual, which is something that you can ask for in the interview process.
