I'd say it comes from some of (order of most to least imo, but I'm only mid level so take what I say accordingly):
* physical processes have a fuzzy good enough. The bridge stands with thrice its expected max load. It is good enough.
* most software doesn't have life safety behind it. In construction, life safety systems receive orders of magnitude more scrutiny.
* physical projects don't have more than 20 different interdependencies; there's an upper limit on arbitrary complexity
* physical projects usually have clearish deadlines (they lie, but by a constant factor)
* The industries are old enough that they check juniors before they give them big decisions.
* Similarly, there exists PE accountability in construction
