Beam splits: ?? / by Scott Newland

We're wondering about some splits in the sides of both glu-lam beams, only noticed recently.  Is this normal for such large members, due to low winter humidity and the long-term drying out of the lumber?  I've asked the engineer at the firm that manufactured them.  Stay tuned!
