Re: 57 Paint Brush Way, Joist Bottom Flange Cut Out, Downstairs Bathroom
Grid Line 4, Between Grids A and B On S3.0.
ISSUE DESCRIPTION: A 11. 7/8” BCI 6000 1.8 floor joist has been cut to allow
passage of a plumbing drain for the fixtures shown in the image in this letter. The cut
extends through the joist, and partially through the top member of the double top plate of
the non bearing 2x6 wall located directly below the joist. The cut is depicted in this
photo:

RECOMMENDATIONS: I recommend adding two single lamination LVL headers at
the cut joist and just severe the member entirely, as depicted in the sketch below. The
hangers for the LVL’s would be an IUS1.81/11.88. The I joist that receive the LVL
header ends would need to be packed out per the BCI recommendations (see attached
sketch). Additional information regarding packout lengths etc. can be found on the BCI
website.
Sincerely,
