the carpet guy was replacing some carpet. it's laid down on a plywood subfloor. i noticed one gap in the laid down panels that you could peek into the basement thru.
you could also get a ruler thru the gap & measure the plywood thickness.
i was shocked to realize it wasn't that thick.
the panels are stamped 23/32, and tongue and groove - google'ing it - it seems the 23/32" is the same as 3/4 - but these panels are NOT even close to being 3/4" thick ...
now i must be missing something here in the way thickness is depicted.
should the panel really be 3/4" thick (ie. measured on a ruler), or is there some "trade" custom in measurements of plywood subfloor thickness that is used ? i would imagine an actual 3/4" thick plywood panel would be a very heavy dead load on the joist.
it actually measured on the ruler a little less than 1/4" thick - and the blueprints call for a standard 40 psf load limit.
