What do you guys do?

We want / need use "FIRST FLOOR SUBFLOOR" over F.F.E. for our dimensioning.  As a solution to the spot elevation issue we had (spot elevations reading "100-0 3/4") we opted to omit the finish floor out of our floor assembly and move all of our doors 3/4" above this level.

the problem is that i now see dual lines below the doors.  Obviously this was unintended.  And it makes sense they are there... So the only option i think i have is to add the finish floor back into the floor assembly and deal with the spot elevations being off by 3/4".

Is there another way to achieve what we're trying to do, or do we just need to adapt to seeing 100'-0 3/4" for a F.F.E. versus a 100'-0" T.O. Subfloor.

Thanks!

hi,

im confused but I want to help,

we normally model it separately (not as an assembly)

one floor type for Subfloor, and one floor type for FINISHES

for the spot elevations, we will tag the FINISHES, spot elevation can show both/or either top and bottom elevations.

so we will have 100'-0 3/4" and/or 100'-0" (on your example)

hope it helps

We don't typically reference "finish floor".  Our floors are the structural floor with sub-base.  Typically, this is what all interior framing is built on so the level is set to the top of this floor.  That means all doors and walls and woodwork is referenced off this level and that is really how we build typically.  Ceramic floors / carpet (if shown) / RVT and wood wood be thin floors modeled on top of this floor.

Obviously, if you have raised computer floors (we add a new level) or some form of floor thicker that 1/2", you may do something different.

That sounds like the solution... We'll model a second floor on top of the sublfloor.  it would be pretty easy to do so. It makes a difference in our stairs.  They need to go from Basement (Slab On Grade) to First Floor Finish Elevation (not subfloor).

Thanks guys!

I'm not sure why i did not think to model the finish floor seperatly then have the spot elevation read "bottom of".
