Unfortunately I expect you’re right. I think I’m really thinking more in terms of a new addition that can be designed from the beginning to accept that load, but I don’t really know how likely that is to come together, or what non-obvious problems there might be with that (e.g. obvious: no plan to build significant addition in near future; non-obvious: everything I don’t know about flight-path design). I wonder how the load of a helipad compares to the load of another floor?
