I don’t think it happens often. Though Lawsuits are not uncommon in civil engineering. When I worked as an EIT (passed the state engineering exam, on way to becoming a Profesional engineer), our office did an analysis on someone else’s slope stability calculations, because the slope wasn’t stable and they wanted to figure out if it was done properly. Civil engineering designs have a clear paper trail and the buck stops with the engineer who signed and stamped the drawings.
