nodrog 0 Posted March 25, 2019 Can anyone tell me what the components of the Floor Structure(L) are? (example: 2x12 + 5/4 + 1/2" sheet rock) I am having difficulty relating this to my actual slab home built in Houston in the year 2000. Share this post Link to post Share on other sites
solver 625 Posted March 25, 2019 The standard floor structure is 3/4" OSB, and 11-7/8" I-Joist. 12 minutes ago, nodrog said: I am having difficulty relating this to my actual slab home built in Houston in the year 2000. You should build a slab for your first floor, if that's what you are asking about. Share this post Link to post Share on other sites
nodrog 0 Posted March 25, 2019 No, I am not asking about the slab. Why is the Floor Structure(L) set at 12 5/8" ? It is a constant variable that should be changeable for each floor. Why is it 12 5/8" ? Do I I need to adjust my Finished Floor(K) to account for this arbitrary constant? Share this post Link to post Share on other sites
solver 625 Posted March 25, 2019 Only Pro has the ability to change framing -- other titles are stuck with the default. If you need a thicker floor, then yes, adjust the finish floor thickness. Share this post Link to post Share on other sites
