There are no provisions in place to climb the curved glass of the spire. Servicing the LED units is not as simple as 'changing a lightbulb', as the curved glass would actually need to be removed in order to accomplish that. How is the climber supposed to do that? What are they supposed to do with the removed unit? How are they supposed to actually climb curved glass? It is not possible to do what you say with the way the building is currently designed.
They use suction cups. That simple.
