There are no changes to the web hole chart in our BCI® joist literature, but there are a couple of edits that have been made to the “Large Rectangular Holes in BCI® Joists” table shown below the main web hole chart (page 7 of the Eastern Specifiers Guide).
The illustration below highlights the changes, and the updated Eastern Specifiers Guide is available within BC Connect® software and www.bc.com, or directly from this link:
