|---|---|---|---|---|---|
| Steel-Frame Skyscrapers (skyscrapers_steel_frame) | enabling | 90% | textbook | Skyscraper frame systems were enabled by early steel-frame structural systems, which are a direct technical precursor. |
|
| Electric Elevators (electric_elevators) | required | 88% | textbook | Elevator systems are the enabling vertical-transport technology for practical high-rise development. |
|
| Electricity (electricity) | enabling | 68% | expert_inference | Electricity provides a capability that enables this technology without being the only possible path. |
|
| Plumbing (plumbing) | enabling | 68% | expert_inference | Plumbing provides a capability that enables this technology without being the only possible path. |
|
