Bank of America Tower
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.

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."

249 m / 816.8 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).

249 m / 816.8 ft
Occupied

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the highest occupied floor within the building.

229.9 m / 754.2 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).

55
Floors Below Ground

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

# of Parking Spaces

Number of Parking Spaces refers to the total number of car parking spaces contained within a particular building.

110
# 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).

30
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.

Under-Construction Chicago Skyscrapers Acquire New Tenants

Real estate investment firm Heitman has inked a lease for 60,000 square feet (5,600 square meters) at Riverside Investment & Development and Howard Hughes’ under-construction...

About 110 North Wacker

Located along the South Branch of the Chicago River, 110 North Wacker was constructed upon a trapezoidal shaped site presenting design challenges in creating desirable lease spans while accommodating for a publicly accessible riverwalk of at least 9.1 meters (30 feet) in width, as required by city ordinance for any riverfront development site. These challenges were addressed by placing the building core within the center of the composite structure and taking the unusual approach of staggering the core walls to maintain a 13.7 meter (45 foot) span of leasable office space on each side of the building. This staggering of the core walls is then reflected in a series of rectilinear setbacks along the west façade, maintaining an orthogonal 1.5 meter (five foot) planning module throughout the building while providing for the equivalent of 14 corner offices per floor.

The building structure is composed of column-free floor spans framed with steel beams linking the central reinforced concrete core to a series of steel perimeter columns which transition into three trident shaped trusses on the riverfront creating an arcade for the riverwalk, which in conjunction with a small pocket park to the north, provides for 50 percent of the site being open-air public space at street level.
