This will leave room for future settle or sag. Good luck!
Thanks for the reply. I am not too concerned with the beams sagging, causing a crack in that location because that is where existing walls run the width of the house, it has been 5 years since construction, etc: although your idea does not sound like a bad one.
I am not worried about the holes per se, more concerned that inserting anchors might crack the floor when I install them. The more I think about this, the less concerned I am I guess.
