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.

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).
These are firms that consult on the design of a building's façade. May often be referred to as "Cladding," "Envelope," "Exterior Wall," or "Curtain Wall" Consultant, however, for consistency CTBUH uses the term "Façade Consultant" exclusively.
Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

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.

Almas Tower is the centerpiece of the Jumeirah Lake Towers Free Zone, a multi-tower office high-rise development. Designed to house the Dubai Diamond Exchange, Almas Tower, or “Diamond Tower” in Arabic, takes inspiration from the unique shape of diamonds. The two-story podium that houses the diamond exchange is one of the building’s most architecturally striking features, with eight triangles inspired by the facets of a cut diamond jutting out from the core.
Along with its podium, the tower is significant for its use of two separate but overlapping conformations attached to a single core. In plan, this unique design appears as two diagonally offset ellipses that converge along their east-west faces. Because the southern component is 12 stories taller than the northern component, the tower has a built-in vertical asymmetry that informs its design. An 81-meter spire attached to the southern mass further distinguishes it from its northern counterpart and marks it as the main structural element of the building. The northern mass appears rounded with a roof slanted to the east, while the southern mass – though still rounded – appears straighter and slimmer with a roof slanted to the west.
Along with visual differences, both conformations have design aspects that address various environmental needs. The northern face is designed to maximize cooler northern sunlight via semi-transparent glass, while the southern face protects against heat gain with a high-performance finish.
The building’s design incorporates high-degrees of flexibility in order to accommodate the needs of the client, including office floors with no less than 80 percent usable space and column-free offices. Ultimately, Almas Tower’s efficient design and expressive configuration make it a unique edition to Dubai’s crowded skyline.
