What you needs to do is put in a couple ground rods around your house.
Since this is a new construction, you may consider running a counterpoise
around the structure, hook up a few ground rods on this counterpoise. Bond
the foundation rebar to the counterpoise. Make sure all the metal panels of
the structure are electrically bonded together and bonded to the
counterpoise.
Then
Put in a proper lighting protection system of Air terminals and down
conductors. Also bonded to the counterpoise.
Then if you puts up a tower and antenna cable grounding bulkhead (at the
entry point to the house, these should also be bonded to the counterpoise
too.

Seems to me that the steel skin is all the air terminal I need, no?
I do wonder from reading several commercial sites discussing specs
for lightning protection that I might be better off locating the
tower right next to the house versus 75 feet away -- the umbrella
of protection thing?
As for additional grounds a building perimeter under 250' repeatedly
was only spec'd for two ground rods "preferably as far apart as
possible" attached to the metal structure.
Based on input from here and the commercial web sites I am thinking
I'll put a 10 foot ground rod at each corner, two at 20 foot
spacings along the side, and bond them all to the steel channel.
I will ask the builder to exothermically weld the rebar to the
anchor bolts at those locations ... just for good measure.
I will tie the entry plate to this system in addition to its
own three 20 foot rods.
That otta cover it, no?
Thanks! & 73, doc kd4e
