I have a 5 unit office building being built in my area. The walls are concrete and the roof is metal. There are iron girders and rafters around 14' above the floor supporting the roof and a drop ceiling around 9' above the floor.
Per section 250.104(C), do you feel this "structural metal" needs to be bonded? I question as to whether or not this sturctural metal is "exposed" per NEC definition and if it is really ever likely to become energized. There is no roof access from the inside of the building nor is there any equipment attahed to these metal parts.
