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.

concrete
Height

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."

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).

Floors Below Ground

The number of floors below ground should include all major floors located below the ground floor level.

# of Apartments

Number of Apartments refers to the total number of residential units (including both rental units and condominiums) contained within a particular building.

55
# of Elevators

Number of Elevators refers to the total number of elevator cars (not shafts) contained within a particular building (including public, private and freight elevators).

2
Tower GFA

Tower GFA refers to the total gross floor area within the tower footprint, not including adjoining podiums, connected buildings or other towers within the development.

About 100 11th Avenue

A crystalline architectural beacon along the shore of the Hudson River, 100 11th Avenue utilizes a multi-pane panelized façade system to impart its signature shimmer to Manhattan’s West Chelsea neighborhood. The main structure is clad with a panelized curtain wall system consisting of 1,650 windows, each a different size and uniquely oriented in space. Conceptually the tower is completely clad in clear glass, while outside views into the apartments are limited as light reflects off the randomly-oriented windows. Rather than reflecting one image, the façade reflects multiple images at the same time. Within the apartments, the floor-to-ceiling glass frames individual views as opposed to panoramic views. The shape of the building owes its uniqueness to curved long-span slabs that contour the corner of 19th Street and the Westside Highway.

The lower six stories of “podium” are encased by a double curtain wall system. The main building façade continues from the sixth floor down to the ground, while a second façade (the Street Wall) is offset 4.9m (16ft) towards the street. The atrium space created by these two faces is filled with an intricate mix of steel framing, concrete cantilevered walls, columns and balconies. This results in an indoor space in which trees are suspended overhead.

An elevated garden is located at the back of the building, supporting up to 2.4m (8ft) of soil and trees and incorporating a skylight opening. The space is structured with a 50.8cm (20in) thick slab spanning 10.7m (35ft) over a swimming pool below. To accommodate the unique façade weight and provide for the long clear spans, the typical 23cm (9in) slab thickens to double in depth at the curved edge of the building.

The building’s lateral loads are resisted using a combination of core shear walls and elongated columns located throughout the building. In addition, studded structural steel was used at concrete link beams to accommodate large beam shear forces, and to limit beam depth. The main core is connected to two columns via in-slab outrigger beams at the curved edge to help minimize building deflections during earthquakes. The seven lateral columns dually provide support for the complex balcony structure that defines the lower stories.
