This 3 inch hole in each of these joists will be acceptable because the 11. 7/8" BCI 6000 1.8
joist (16 inches on center) has the capacity to span the entire joist length without considering
the center
bearing wall as a bearing point. Per the BCI hole schedule for 11. 7/8" I joists, we can have a 3
inch dia. hole so long as we are no closer than
1 ft 7 inch from an END bearing support. We are more like 6 ft from the end reaction, so we are
good.

Hey Mic,
We ran into another issue at the Coon Residence. The electrician drilled a 3 inch hole
through the floor joists clouded below. I included some photos in the attached with some
measurements (3 inch diameter hole, approximately 6 inches to center of each hole). Let me
know if you want to get on the phone tomorrow to discuss or if you need any additional
information or photos.
Thank you,
