The electricians drilled a few 7/8" hole through one of our LVL's. I checked and per a Roseburg Forest Products booklet holes up to 2" are permitted as follows:

No more than 3 holes.
Square and rectangular holes are not permitted.
Does not apply for cantilevers.
Hole to be centered on height of beam.
Holes (if more than one) must be a minimum of 4" clear distance between holes.
Hole must be at least 2 1/2 times height of beam away from load bearing point.

"On purpose"? Did you talk to my plumber? I accidentally drilled though an ABS drain pipe when doing the low voltage pre-wire.
