Wikidata contains other height values. The ranking uses the explicitly identified architectural height in the linked measurement source; tip, roof and proposal heights are not interchangeable.

Project evidence, construction records and the limits of what is documented. A named consultant’s role is kept separate from the architect, contractor and local engineer of record.
A project-team technical narrative has not yet been verified for this building. The evidence register below identifies the recorded details and the information still needed for a full account of its structural and construction systems.
| Topic | Recorded information | How to interpret it |
|---|---|---|
| Structural system | Not confirmed | The frame description needs to distinguish gravity support from wind and earthquake resistance. Read the engineering guide ↗ |
| Main structural material | Not confirmed | A material label does not establish steel grade, concrete strength, fire protection or connection details. Read the engineering guide ↗ |
| Basement levels | Not confirmed | Basement count does not establish pile depth, founding stratum, bearing pressure or the excavation sequence. Read the engineering guide ↗ |
| Elevator count | 54 [source] | Car count does not establish passenger capacity, speed, zoning, redundancy or peak traffic performance. Read the engineering guide ↗ |
| Construction start | Not confirmed | A start year can refer to enabling works, foundations or the main construction contract. Read the engineering guide ↗ |
| Structural topping out | Not confirmed | Topping out marks a structural milestone; facade work, commissioning and occupancy can follow later. Read the engineering guide ↗ |
The directory records 450 metres of architectural height and 89 above-ground floors. The highest occupied level has not been confirmed here. Measurement source ↗
Dividing architectural height by floor count would include the crown and any unequal floor heights. It cannot be used as a typical floor-to-floor dimension, a measure of slenderness or a structural design input.
Foundation tests, core and column sizes, construction-stage stability, creep and shortening allowances, wind-tunnel results and facade movement tolerances need project-specific evidence. Their absence here does not imply that the project lacked those studies.
Height bars use the same scale. They do not represent building shape. Measurement source ↗
