Steel Beam Boring?

Typical Architect/Engineer, they always leave it to the Contractors interpetation and when it fails, they say it was not done as it was drawn or intended. ha. ha.

Of course, the architect/engineer could say "typical contractor, can't read drawings", and in this case he'd be right.

Well, I guess I asked for that one Richard, didn't I? ha ha

Model building codes and typical job specs refer to AISC and AWS specifications for steel fabrication, which require that any interior corners ("re-entrant" corners) on cut steel ... such as the corners of the hole in the diagram Marcel posted ... be rounded, with the radius depending on the application/materials. In addition the cut surface must be reasonably smooth (2,000 u" or less).

I agree that the left side of the hole should also show rounded corners and/or that radius call-out should say "Typical". However, builders still need to know and follow the AISC/AWS fabrication specifications.

But any steel holes or cut-outs should be designed.
