John,
What sort of material is that in them I-Beams?.
Is it some sort of Laminated Timber?.
I was always told that all penetrations though large wooden beams, had to be on the centre-line of the vertical width of the beam.
I'm told that the compressional forces on the beam materials are zero at this point.
Sorry to pick holes in your work, mate. [Linked Image]
