I understand the idea but there's a threshold of diminishing returns when putting too much pressure on a position. Lots of doctors work with lawyers in mind, and will refuse tasks because of risk. Other fields have similar subpar performance due to high responsibility stress.
We need to increase quality but not at the expense of people working.
As a former civil engineer, at least in the US you need a license from the state to stamp a design before anyone will build it, so accountability is built into the process.
Its actually stressful and the pay isn't that great. I did mostly landfill design which is a little different, but slope stability and retention pond calculations were always checked and double checked.
Though there is always ongoing maintenance which would be the owner responsibility.
