Drilling 2" hole through steel beam...
(OP)
There are 4 existing steel beams supporting the roof of a structure. The beams are 42" x 3/8" web with four L's that are 6"x6"x5/8". The beams are 60' long clear span. The client is wondering if he can drill 2" holes through the beam to install a stormwater drain. There would be 5 holes drilled in the beam approximately equal spaced along the 60'. Can someone steer me in the right direction to where I can begin to determine if a 2" hole can be drilled through the beam and if it needs to be reinforced. Thank you.

So as long as the holes are in the middle third of the beam he should be all set right
