Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

Structural Material
Steel
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.

Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

Height
Architectural
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."

330.0 m / 1,083 ft

To Tip
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).
330.0 m / 1,083 ft
Floors Above Ground
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).

NIKKEN SEKKEI LTD
Architect of Record

Usually takes on the balance of the architectural effort not executed by the "Design Architect," typically responsible for the construction documents, conforming to local codes, etc. May often be referred to as "Executive," "Associate," or "Local" Architect, however, for consistency CTBUH uses the term "Architect of Record" exclusively.

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.
WSP
Peer Review

The Peer Review Engineer traditionally comments on the information produced by another party, and to render second opinions, but not to initiate what the design looks like from the start.
Aurecon
Project Manager

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.
Mace Limited
Main Contractor

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.

About One Za'abeel Tower 1

The One Za’abeel development takes the idea of the “gateway” to a new level. The two towers, containing office functions (Tower 1, 330 meters) and residential / hotel functions (Tower 2, 235 meters), are positioned on either side of an elevated highway. A horizontal “Link” structure connects the two towers and proceeds past the edge of Tower 1 in a dramatic cantilever, providing additional structural stability as well as a signature event space. The Link, suspended 100 meters above the ground, offers a choice of attractions, including restaurants, lounges, cafes, bars, and observation deck, a gym, a spa, a pool, a banquet hall and a rooftop terrace.

The superstructure for the hotel and residential floors of both towers is comprised of a concrete core-and-outrigger system, which allows different column grids for each function. The system is based on a 3-meter module. The Link structure is a perimeter diagonal tube, with sufficient vertical and torsional stiffness and strength, so as to provide column-free space on its upper level.

The podium inclines from ground level to the roof, and is abundantly crowned with greenery and water bodies. The lobby of the hotels and serviced apartments is located on the lower levels of the slope, with welcoming views over water features, greenery, and the Link above. The top surface of the podium is richly landscaped, covering the entrances and drop-offs with shade.
