bonding and grounding of steel tube framed fabric cover buildings

Question asked by Brad Boltz on Dec 15, 2017

We are adding power to two steel tube framed fabric covered buildings and need to properly bond and ground/lightning protect all metal objects. Is there a standard/code for this structure or best practice information as I have looked and found absolutely nothing. We are looking at 4/0 copper conductor to all the steel and an additional ground rod as a minimum right now. Thank you for any info you can provide.
