Having never worked with steel in my life (apart from when I made
a small hammer in CDT in school) I'm just trying to prepare myself
for the worst and have a few questions:-

1. How do you go about drilling big holes in RSJs?

Drill a ring of holes, then join them using a larger bit, or
use a tank cutter type saw.


2. Is it possible to cut RSJs?

Yes. Hacksaw or angle grinder, go through both flanges and
stop cutting 3/4" before the two cuts meet on the web, twist
each end and the steel will shear.
