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).

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.

residential / hotel

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.

About Trump International Hotel & Tower

The Trump International Hotel & Tower stands at 401 North Wabash Avenue in Chicago, the site of the former Chicago Sun-Times building. The tower includes the 339-room Trump International Hotel, 486 luxury condominium units, 9,300 square meters (100,000 sq ft) of riverfront retail space, 960 parking spaces, restaurant, banquet space, health club, spa, lounges and a ground floor beautified by a landscaped riverfront public plaza and a riverfront promenade.

The tower creates a significant new addition to the Chicago skyline and changes the way in which individuals experience the Chicago River. Shaped to reflect its orientation along the riverfront, the tower’s width is sensitive to its urban surroundings. The south side of the tower parallels the river bank, enabling the structure to connect with Chicago’s north–south grid. Adding to the tower’s sculptural quality, the building’s massing is lifted by 12 meters (40ft), opening up an expansive, landscaped promenade that steps down, like terraces on a hillside, for three levels until it meets the Chicago River. This promenade establishes a pedestrian connection between Michigan Avenue and State Street. By providing public assembly spaces and retail activity at the river’s edge, the tower will connect two bustling areas together: North Michigan Avenue and the Loop.

The tower relates to its neighbors through a series of setbacks, the first of which occurs on the east side, at a height that is essentially the same as the cornice line of the Wrigley Building. The next setback, on the west side of the tower, relates to both the height of the residential tower to the north and Marina City, to the west. The third and final setback is on the east side of the tower and relates to the height of the IBM Building immediately adjacent.

The lateral structural system for the Trump Tower consists of a concrete core and outrigger system. Concrete was chosen as the primary structural material to take advantage of its ability to provide a stiff frame with high damping. The tower foundation consists of a three meter (10ft) thick mat supported on rock caissons. It is believed that the 3,823 meters cubed (5,000 yd3) mat foundation pour represented the largest single self-consolidating concrete placement in North America to date.

As part of the tower’s sustainable strategy, Chicago River water is used to cool the building. The building’s cooling system returns the water back into the river, unlike buildings with conventional cooling towers. A computerized-control system regulates the temperature and ventilation of the building, determining how much the air must be conditioned. Partial green roofs can be found on the tower’s terrace levels. Each of the 3 meter by 1.5 meter (10ft x 6ft) curtain wall panels are made of thermal-pane glass encased in aluminum, with a thermal coating that helps retain heat in the winter and cool air in the summer.

Early on in the design and development of the project, the client identified the desire for a project with phased occupancy. The occupancy phasing was incredibly unique—while the bottom 30 floors of the hotel were completed, occupied and functioning, construction continued on the remaining 60 floors. This phased occupancy required a concerted effort of the project management staff to meet regularly with the City of Chicago inspectors and Building Department heads.
