Since when?
Design criteria baked into international building code is quite robust; not just naive static load, but wind, snow, seismic activity, fire/flood/termite resistance, etc. are all considered. That's a far stretch from something that can "barely stand".
Since always

“Barely stands” in this context is “Barely passes code”, as in “any idiot can build a bridge that stands, it takes an engineer to build a bridge that barely stands”.
