A 2x4 might take 30 seconds longer to combust, true, but it’s impracticable to clean up every little pile of sawdust at the end of the day, particularly on projects at the scale of this one. Regardless of whether there are piles of sawdust lying around (there are on every stick-built project, with the exception of ultra-luxury residential, and then only if you have an OCD Construction Administrator), every wood-frame project is a tinderbox waiting to go up until it’s gyp-boarded and has exterior sheathing in place.
(I say this as a building industry professional with several years of wood-frame and concrete structure Construction Administration under my belt, in sectors from multi-family,like the project in the video, to ultra-luxury single-family).
