What if the engineer who "stamps" the software is outsourced to a 3rd party company that has the necessary certification to avoid gross negligence. So the engineer has followed the protocol as det my law and has done everything right, they can't be liable.
Happened at my uni, look at the comment below.
You’re hung up and confused by certifications, which are a different animal. Look up what PE license actual are and how they function.
You can’t just outsource a design for a bridge to avoid responsibility. If that bridge is being built in California, an engineer who is licensed in California ultimately has to stamp the design, even if all the design work was done elsewhere.
