I have a challenging project upcoming. The scope involves installing a complete new lightning conductor (surface run) of an 18th storey building. Any advice on the best cost-effective way to run the conductors ?
Have a professional with experience and training plan and perform this task.
Asking an internet forum how to properly install lightning protection on a high rise building just doesn't sit right with me, nor would it with the owners of that building or their insurance company.
Put a couple rods on the roof connect them with a wire and throw the roll off the edge. Then open a few windows and either use duct tape or velco to attach the wire to the building. Done, collect $35K and go get lunch.
NFPA 780 is a perfectly valid engineering standard. There’s an IEEE one but 780 is more nuts and bolts oriented. It’s not a regulatory requirement in US but it is a consensus standard. It holds the same status elsewhere in the world.
I agree with getting a professional involved. I would also visit a building that has this type of system installed to get an idea of what it would take.

I have never installed a lightning protection system. I have seen them specified in RFPs. I think the only one I've seen around here is the Erico (now Pentair) brand.
I read through their literature in order to make sure I didn't mess anything up when working around it installing rooftop equipment. Not saying I'd do it without consulting with an engineer experienced with it, but it really doesn't seem like there's all that much to the design. Look in this guide from Caddy for the rolling sphere method for laying out the air terminals, the little lightning rods:
Seriously?
What is the building material?
Is it a skim surface with a 2 inch layer of foam under it?
Does the building have a suspended aerial platform to clean windows?
If it does then what training is needed to run platform or is this like installing generator and and another trade is needed ie do you need to have someone run the the machine for you?
You need to shut off surrounding area around work?
Your project is easy if you have access to an aerial platform if not then you are ****ed because no electrician is going to be in a bosum chair clipping supports to hold wire in place
