Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest point of the building, irrespective of material or function of the highest element (i.e., including antennae, flagpoles, signage and other functional-technical equipment).
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."
Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.
The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).
The number of floors below ground should include all major floors located below the ground floor level.

Usually involved in the front end design, with a "typical" condition being that of a leadership role through either Schematic Design or Design Development, and then a monitoring role through the CD and CA phases.
The Design Engineer is usually involved in the front end design, typically taking the leadership role in the Schematic Design and Design Development, and then a monitoring role through the CD and CA phases.
The CTBUH lists a project manager when a specific firm has been commissioned to oversee this aspect of a tall building’s design/construction. When the project management efforts are handled by the developer, main contract, or architect, this field will be omitted.
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

The main contractor is the supervisory contractor of all construction work on a project, management of sub-contractors and vendors, etc. May be referred to as "Construction Manager," however, for consistency CTBUH uses the term "Main Contractor" exclusively.
Other Consultant refers to other organizations which provided significant consultation services for a building project (e.g. wind consultants, environmental consultants, fire and life safety consultants, etc).
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

Upon completion in 2012, Keangnam Hanoi Landmark Tower was the tallest building in Vietnam and was a redefining moment for the city of Hanoi, which at the time had very few tall buildings. The 72 story building is comprised of offices and is the tallest in a three building complex featuring two 49 story residential towers with curved facades to maximize views. While the complex is located on the western edge of the city, the placement positions the development within the center of a newly established central business district.
In order to construct the complex in the soft soils of Hanoi, 980 piles with diameters of up to two meters across were drilled deep underground in a process which took longer than one full year during the construction phase. The reinforced concrete frame of the 72 story tower utilized post-tensioning which allowed the structure to rise as quickly as of one floor every five days, a rate which is faster than what would have occurred with conventional construction techniques. Cladding the tower is a double glazed façade, producing a desired modern aesthetic for the exterior which combined with an intelligent building systems technology, provides a high level of energy efficiency. At the peak of construction, the worksite employed as many as 8000 people at one time.
The base of the Keangnam Hanoi Landmark Tower is attached to a shared podium structure containing shops, a department store and a cinema from which all three towers then rise. The main tower then is comprised of offices on floors 12-46, serviced apartments on floors 48-60 and a full service hotel on floors 62-70. The uppermost 72nd floor contains an observatory with a panoramic view of Hanoi and its rapidly growing skyline.
