Kieran,

Good start mate. I am expecting a uilging of that size to have a
3 phase supply, probably lead covered armoured looking at the age and
state of repair of the building.

Guessing we would need a distribution board with RCD breaker and MCB's.

As far as cabling and containment, I think it wll depend on 3 things,
load, environment and cost. We will need to be mindful of what we
can deliver and what our budget is. Better to deliver a good basic job
that run out of money trying to do fancy stuff. I think our main issues
will be luminaires on the shooting lanes, as fully protected fittings do
not come cheap. Maybe we could think about halogen floods to light the
lanes from behind the shooter, relatively cheap and bright enough for the job.

I will put some more thought into it once we have the drawings put
together, but, think about Earthing/Bonding, in an all steel shelled building
there will be plenty of it.
