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."
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).

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).
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.
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.

Material Supplier refers to organizations which supplied significant systems/materials for a building project (e.g. elevator suppliers, facade suppliers, etc).

This past decade, “student skyscrapers” have re-emerged at or near university campuses and city centers. As such, the vertical dorm is making a comeback after...
Het Strijkijzer is a fully pre-cast residential tower with an L-shaped plan. Sited on a triangular site of only 37 meters by 34 meters (121 by 111 feet) at one of The Hague’s busiest intersections, the building takes cues from The Flatiron Building in New York City (1902) in its form. The building contains luxury apartments and studios intended to provide an affordable housing option to young adults and students. There are also many public features on the first three levels, and a Grand Cafe surrounded by an outdoor gallery on the top floor with separate elevator access.
With the small site completely occupied by the building, there was no room for a construction staging area, and as such innovative construction methods were developed. Two different companies prefabricated the concrete floor and wall pieces. The delivery trucks would have to meet on the highway and ensure they were driving in the correct order so that when they arrived at the site, the parts could be taken from the trucks and installed on the building immediately. This led to an incredible construction speed of two floors a week.
