ouch on the Helipad, sorry.
On the FBO. I feel for airports, we need those things which are important to pilots. FBO's are of great importance as essentially every general aviation flight will terminate at an FBO - outside the home airport. These are facilities which host boarding for private jets - often luxury hotel style lobbies with fireplace, seating, tables, etc... also, planning rooms, coffee/tea/snacks. Very different from a "fuel station" as the fuel often arrives to the airplane in a truck. Fixed fuel stations are appropriate for self-filling stations. But should be distinct from motor petrol imo.
